Snippets Vault

http://www.mpgh.net/forum/160-tools/...l-release.html

The Snippet Vault:
The Snippet Vault is a Stickied thread created in a effort to answer
those small questions before they have to be asked.

The rules of this thread is simple:

• This thread is open and will stay open.
• This thread is stickied and therefore can be posted in > 7 days.
• You can post in this thread, but if you post anything it [b] contain]/b] a snippet of code as well.
  for the sake of keeping it uniform
• This section is not for "How to Run Visual Basic .NET" or "Download Visual Basic .NET Express from" , It will be used for Snippets of code only.
• If you leech the snippet, Give credit, (even if it is MSDN Standard)
• Check the posts before yours, don't post existing snippets or alternatives to snippets, it is not needed and will be removed.

Post your Snippets here and share them.

For our purposed when I say Code snippets that includes Very short tutorial (like add 2 text boxes and goto code)(Nothing extensive, save those tutorials for the tutorial section.) or a few lines of code to accomplish something Small.

My Snippets (gathered from my tutorials)

- Note: Some code snippets are MSDN standard.

Just another collection of code snippets from me to you.
(also check out my UI Snippets)

Use this as a "Quick Reference Guide" when you need to remember "how to it"

Print a Textbox

* Every where I go , I see all this complex code, and all these Imports and just ugly code, I think a rumor started along time ago that printing a single textbox was hard and required system.drawing and ever since then, everyone just copied and pasted everyone else's code and slightly modified it and called it as thier own. I am here to break that rumor

Simple Print TextBox 1


[highlight=vbnet]

PrintDocument1.PrinterSettings.Copies = 1
PrintDocument1.Print()
[/highlight]

Then Add this

[highlight=vbnet]

Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

e.Graphics.DrawString(TextBox1.Text, TextBox1.Font, Brushes.Blue, 100, 100)

Here is how to Create your own sleep method which will pause what you want to pause, but still allow the application to function

[highlight=vbnet]

Private Sub Sleep(ByVal PauseTime As Double)

Dim Tind As Int16
For Tind = 1 To PauseTime / 50
Threading.Thread.Sleep(50)
Application.DoEvents()
Next

End Sub

[/highlight]

Note: the Application.DoEvents Will allow your application to function normally during sleep


Now you can call a "proper" Sleep

[highlight=vbnet]
Sleep(time to sleep)
[/highlight]


Changing XML Node Values


[highlight=vbnet]
Dim root As XElement = XElement.Load("Location\Filename.xml")
Dim xt As XElement = (From el In root.Descendants("Node1") _
Select el).First()
xt.SetValue("New Value")
root.Save("Location\Filename.xml")
[/highlight]
You can do this dynamically as well by using the value fields with combo-box data or textbox values, etc.


Create A Tab Delimited Text File with listcheckedbox

I notated everything to help you get the basic understanding, Hope this works without special encoding. (as far as the .gct is concerned)

Using ChecklistBox

---- Add Two Buttons
---- Add One TextBox
--- Add One CheckedListBox

Button 1 Text should be - Add
Button 2 Text should be - Save as .GCT

Button One Click Event

' This adds the item of textbox1.text to your checkedlistbox
[highlight=vbnet]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CheckedListBox1.Items.Add(TextBox1.Text)
End Sub
[/highlight]

Button Two Click Event
' This Calls the sub SaveCheckedlistBox which will save the checked list box of your choice
' The format is SaveCBox(clb)
' CLB = the name of the checkedlistbox you want to save as tab delimited
[highlight=vbnet]
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
SaveCBox(CheckedListBox1)
End Sub
[/highlight]

Now add this code below the above

' This is the part of the sub that saves the checked listbox as a .GCT Text file, with tabbed delimited format

[highlight=vbnet]
Private Sub SaveCBox(ByVal clb As CheckedListBox)
' Declares Save dialog as a new instance of Save File Dialog
Dim SaveDialog As New SaveFileDialog
' Allows us to add extensions, if this is false then extensions would be *.* All Files
SaveDialog.AddExtension = True
' The default extension is set to .GCT (the format you are looking for)
SaveDialog.DefaultExt = ".gct"
' This sets the save as combo-box items
' The Format is "Description|Extension"
SaveDialog.Filter = "GCT Files|*.GCT|All Files|*.*"
SaveDialog.FilterIndex = 0
' Sets the Text on the Title
SaveDialog.Title = "Save List Box as GCT"
' Saves the listcheckedbox as a .gct in tab delimited format.
If SaveDialog.ShowDialog = DialogResult.OK Then
Dim sw As New System****.StreamWriter(SaveDialog.FileName)
For i As Integer = 0 To clb.Items.Count - 1
Dim t As Boolean = clb.GetItemChecked(i)
sw.WriteLine(clb.Items(i).ToString & ControlChars.Tab & t.ToString)
Next
sw.Close()
End If
SaveDialog.Dispose()
End Sub
[/highlight]

Run Application from Resources

Name Space
[highlight=vbnet]
Imports System****
[/highlight]

Now this in a button click (or whet ever triggers the event)

[highlight=vbnet]
Dim RPath As String = Application.StartupPath & "\File.exe" 'File.exe will be a temp name given to your exe, you can make it anything you want, or keep it as is.

' Will create the file with the given name
Using CreateFile As New FileStream(RPath, FileMode.Create)
CreateFile.Write(My.Resources.YourResource, 0, My.Resources.YourResource.Length)
End Using
' Start the application
Process.Start(RPath)
[/highlight]

Note: "Your Resource" in my code example above needs to be the EXE name without the exe extension, so for example, if you add notepad.exe as a resource, then the code would be

[highlight=vbnet]
Dim RPath As String = Application.StartupPath & "\File.exe"

Using CreateFile As New FileStream(RPath, FileMode.Create)
CreateFile.Write(My.Resources.Notepad, 0, My.Resources.Notepad.Length)
End Using

Process.Start(RPath)

Extracting specific piece of string between brackets:

Suppose this is the string:

"[Hello][Bye]CakeBuster[Dead]"

The following function will extract 'CakeBuster' from the above string.

[highlight=vbnet]Dim Source As String = "[Hello][Bye]CakeBuster[Dead]"
Dim _1 As Integer = Source.LastIndexOf("[")
Dim Ex1 As String = Mid(Source, 1, _1)
Dim _2 As Integer = Ex1.LastIndexOf("]") + 2
Dim FinalExtraction As String = Mid(Ex1, _2)[/highlight]

A little explanation:

Dim _1 As Integer = Source.LastIndexOf("[")

This line gets the index (number) for last "[".

Dim Ex1 As String = Mid(Source, 1, _1)

This will store the string up to last "[" but not after that.

Dim _2 As Integer = Ex1.LastIndexOf("]") + 2

Similarly this will get the last index of "]" in the new string which is Ex1 now !!

Dim FinalExtraction As String = Mid(Ex1, _2)

Finally, extract the word you need by starting the string from "]".

Here is a string manipulation library from CodeProject:

Just create a new module named 'StringFunctions' and paste the following code in it:

[highlight=vbnet]Imports System.Text

Module StringFunctions
'Retrieves the path part of a full filename
'C:\Folder\file.exe -> C:\Folder\
Public Function GetPath(ByVal Full As String) As String
For i As Integer = Full.Length - 1 To 0 Step -1
If Full.Substring(i, 1) = "\" OrElse Full.Substring(i, 1) = "/" Then 'Find the rightmost \ or /, which should be cut off the file part
Return Full.Substring(0, i) & "\"
End If
Next
Return ""
End Function

'Retrieves the name of the file from a filename
'C:\Folder\file.exe - > file
'OR
'file.exe -> file
Public Function GetName(ByVal Full As String) As String

Functions are:

GetPath(<Full Path>)
The function retrieves the path part from the full filename like, C:\Folder\file.exe -> C:\Folder\.

GetName(<Full Path>)
It retrieves the name of the file from the full filename like, C:\Folder\file.exe - > file, file.exe -> file.

GetExtension(<Full Path>)
It retrieves the extension of the file from a filename C:\Folder\file.exe - > exe, file.exe -> exe.

RemoveExtension(<Full Path>)
It removes the extension from a filename like, C:\Folder\file.exe - > C:\Folder\file, file.exe -> file.

GetFullName(<Full Path>)
It removes the path from a filename like, C:\Folder\file.exe - > file.exe.

IsCapitalized(<String>)
It checks whether a word or sentence is capitalized like, Word -> True, This is a sentence -> True.

IsLower(<String>)
It checks whether a word or character is in lower case like, word -> True, Word -> False.

IsUpper(<String>)
It checks whether a word or character is in upper case like, word -> False, Word -> False, WORD -> True.

SwapCases(<String>)
It swaps the cases in a string like, word -> WORD, Word -> wORD, WoRd -> wOrD.

AlternateCases(<String>)
It alternates the cases between letters of a string, the first letter's case stays the same like, Hi -> Hi, longstring -> lOnGsTrInG.

IsAlternateCases(<String>)
It checks to see if a string has alternate cases like, lOnGsTrInG -> True.

IsMixedCases(<String>)
It checks for mixed upper and lower cases like, string -> False, String -> True.

CountTotal(<String>, <Chars>)
It counts total number of a string or character in a string like, hello, l -> 2, hello, he -> 1.

RemoveVowels(<String>)
It removes vowels from a string like, remove -> rmv.

HasVowels(<String>)
It checks to see if a string contains vowels like, hello -> True, rmv -> False.

IsSpaces(<String>)
It checks if a string is nothing but spaces like, " " -> True.

IsNumeric(<String>)
It checks if a string has only numbers like, 12453 -> True, 234d3 -> False.
I know that there is already an existing IsNumeric function, but the existing one takes the input parameter as an Object, so in theory, this function should be faster for larger strings because it takes the input as a String.

HasNumbers(<String>)
It checks if the string contains numbers like, hello -> False, h3llo -> True.

IsAlphaNumberic(<String>)
It checks if the string has numbers and letters like, Test1254 -> True, $chool -> False.

IsLetters(<String>)
It checks if the string contains only letters like, Hi -> True, Hi123 -> False.

Initials(<String>, <Capitalize>, <ReturnSeparator>, <Optional Separator = " ">)
It returns the initials of a name or sentence.

* Capitalize- To return the initials as lower or upper case.
* ReturnSeparator - To return the initials with the original separator (John Smith, a space is the separator, so return J. S. or J.S.).
* Separator - The character that marks the separation of words (John Smith, space is the separator (default)) John Smith -> J. S.

Title(<String>, <Optional Separator = " ">)
It capitalizes the first letter of every word in the string like, the big story -> The Big Story.

IsEmailAddress(<String>)
It checks if a string is in a valid email address-format like, name@place.com -> True, hahaimfaking -> False. (The function works by assuming the last part is no bigger than 3 letters (com, net, org).)

IndexesOf(<String>, ByVal [Char] As String) As Integer()
It returns all the locations of a given char in a string like, Hello, l -> 2, 3, Hello, o -> 4.
This function works with an ArrayList and then converts it to an Integer array, if you prefer the ArrayList it can be easily modified.

CharRight(<String>, <Position>) As Char
It gets the char in a string at a given position, but from right to left like, string, 0 -> g.

CharMid(<String>, <Position>, <Start>) As Char
It gets the char in a string at a given position from a given starting point, and reads from left to right like, string, 0, 2 -> r.

InsertSeparator(<String>, <Separator As String>)
It inserts a separator after every letter like, hello, "-" -> h-e-l-l-o.

InsertSeparatorEvery(<String>, <Separator>, <Count>)
It inserts a separator after every Count letters like, hello, "-", 2 -> he-ll-o.

Substring(<String>, <Start>, <End>)
This is a function that works the same way as the default Substring, but it takes Start and End parameters instead of Start and Length.

Reverse(<String>)
It reverses a string like, Hello -> olleH.

PasswordStrength(<String>) As Integer
It is a borrowed function. It returns a rating for how strong the string is as a password. (Max rating is 100).
The credits for the original function goes to D. Rijmenants, this is just a VB.NET version. If there is any problem with copyright or whatever, contact me and I'll delete this. This is just an interesting function that took me a long time to find, so I thought it'd be useful to include it here.

Split(<String>, <Optional Don't Account for Quotes>, <Optional Separator>)
This function is newly added (on 9/27/05). Thanks to j1webb for the idea. This is just like the default Split function, but it keeps everything inside the quotes, intact. For example: 'This is a "very long" string' would return 'This', 'is', 'a', 'very long', 'string'. A limitation of this function is that if there's a quote inside quotes it will mess up. The quote symbol is " by default, but it can be changed to look for ' instead.

Hope this helps !!!

Here's a simple but useful one. These are 2 easy ways to convert a color from a string.

[highlight=vbnet]Color.FromName("Blue") 'Whatever color name you want in those brackets

This is my memory editing snippet. Just place this code inside a module and use it in your programs if you wish Unfortunatly, i had coded this module in vb6, so not every command will work with vb.net. You may translate if you wish, i just ask that you re-post for others to use.

Alright. In order for this to work, im gonna show you a quick example using that cheezy little Pinball game that comes with Windows XP.

lets say we turned the game on and made a button that we set the button command to this: [highlight=vbnet]
Private Sub Command1_Click()
Call WriteALong("3D Pinball for Windows, Space Cadet", &HA12EF4, 999999)
Call WriteALong("3D Pinball for Windows, Space Cadet", &HB8AEBA, 999999)
End Sub
[/highlight]

Basically what the code means, is that i Called the function "WriteALong" from the module that is just above. "3D Pinball for Windows, Space Cadet" is the window title, &HB8AEBA is the address. "999999" is the value you set that specific address to.

*Note: Add &H instead of the 2 00 (two zero's), Here's an example: Your address is 00L1FD4. You need to replace the 00 (two zero's) with an &H , then you would get this: &HL1FD4. If there is only 1 0 at the beginning then just replace it with an &. If there are no zero's at the beginning then this rule does not apply.


And thats it!

oh and p.s. This is basically how people use VB and make trainers for games and such.

Reading the header of a .mp3 file to get the Artist/Year/Album/Title.

Create the following class:

[highlight=vbnet]Imports System.IO

Public Class MP3TagData

Private _Artist As String
Private _SongTitle As String
Private _Album As String
Private _Year As String

Public ReadOnly Property Artist() As String
Get
Return _Artist
End Get
End Property

Public ReadOnly Property SongTitle() As String
Get
Return _SongTitle
End Get
End Property

Public ReadOnly Property Album() As String
Get
Return _Album
End Get
End Property

Public ReadOnly Property Year() As String
Get
Return _Year
End Get
End Property

Public Sub ReadFromFile(ByVal filename As String)
' Bereits vorhandene Werte l?schen.
Me._SongTitle = ""
Me._Artist = ""
Me._Album = ""
Me._Year = ""
Dim fs As New FileStream(filename, FileMode.Open)
' MP3-Tag lesen.
fs.Seek(0 - 128, SeekOrigin.End)
Dim Tag(2) As Byte
fs.Read(Tag, 0, 3)
' ?berpr?fen, ob ein Tag vorhanden ist.
If System.Text.Encoding.ASCII.GetString(Tag).Trim() = "TAG" Then
' Titel.
Me._SongTitle = GetTagData(fs, 30)
' K?nstler.
Me._Artist = GetTagData(fs, 30)
' Album.
Me._Album = GetTagData(fs, 30)
' Jahr.
Me._Year = GetTagData(fs, 4)
End If
fs.Close()
End Sub

Private Function GetTagData(ByVal stream As Stream, _
ByVal length As Integer) As String
' Daten lesen.
Dim Bytes(length - 1) As Byte
stream.Read(Bytes, 0, length)
Dim TagData As String = System.Text.Encoding.ASCII.GetString(Bytes)
' Nullen abschneiden.
Dim TrimChars() As Char = {Char.Parse(" "), Char.Parse(vbNullChar)}
TagData = TagData.Trim(TrimChars)
Return TagData
End Function

End Class[/highlight]

On button click_event or wherever:

[highlight=vbnet] Dim MP3Tag As New MP3TagData
Dim Dateiname As String = "C:\test.mp3"

Try
MP3Tag.ReadFromFile(Dateiname)
Catch ex As Exception
MsgBox(ex.Message.ToString)
End Try


Dim album As String = MP3Tag.Album
Dim artist As String = MP3Tag.Artist
Dim title As String = MP3Tag.SongTitle
Dim year As String = MP3Tag.Year[/highlight]

@Above, I'd suggest using Phenix module since it is working with the process and not with the window name.

Here is a module with code for encrypting and decrypting strings.

Here is another module. This time its for setting debug privileges in the case that you dont have them.
And here is a module for DLL injection on 32-Bit OS's

First add this function:

Then this sub-procedure:

Then call it from whereever you want like:

Snap Form To Screen Borders:

This feature allows you to drag your window near the screen border and have the window automatically get pulled towards that border like a magnet. It's Perry Marchant's implementation of VB.NET.

■ Import this namespace to the form:

[highlight=vb.net]Imports system****ntime.InteropServices[/highlight]

■ Declare the following:

[highlight=vb.net] Private Const mSnapOffset As Integer = 35
Private Const WM_WINDOWPOSCHANGING As Integer = &H46

<StructLayout(LayoutKind.Sequential)> _
Public Structure WINDOWPOS
Public hwnd As IntPtr
Public hwndInsertAfter As IntPtr
Public x As Integer
Public y As Integer
Public cx As Integer
Public cy As Integer
Public flags As Integer
End Structure
[/highlight]

■ After that add these sub-procedures to the program:
[highlight=vb.net]Protected Overrides Sub WndProc(ByRef m As Message)
' Listen for operating system messages
Select Case m.Msg
Case WM_WINDOWPOSCHANGING
SnapToDesktopBorder(Me, m.LParam, 0)
End Select

MyBase.WndProc(m)
End Sub

Public Shared Sub SnapToDesktopBorder(ByVal clientForm As Form, ByVal LParam As IntPtr, ByVal widthAdjustment As Integer)
If clientForm Is Nothing Then
' Satisfies rule: Validate parameters
Throw New ArgumentNullException("clientForm")
End If

' Snap client to the top, left, bottom or right desktop border
' as the form is moved near that border.

Try
' Marshal the LPARAM value which is a WINDOWPOS struct
Dim NewPosition As New WINDOWPOS
NewPosition = CType(Runtime.InteropServices.Marshal.PtrToStructu re( _
LParam, GetType(WINDOWPOS)), WINDOWPOS)

If NewPosition.y = 0 OrElse NewPosition.x = 0 Then
Return ' Nothing to do!
End If

' Adjust the client size for borders and caption bar
Dim ClientRect As Rectangle = clientForm.RectangleToScreen(clientForm.ClientRect angle)
ClientRect.Width += SystemInformation.FrameBorderSize.Width - widthAdjustment
ClientRect.Height += (SystemInformation.FrameBorderSize.Height + SystemInformation.CaptionHeight)

' Now get the screen working area (without taskbar)
Dim WorkingRect As Rectangle = Screen.GetWorkingArea(clientForm.ClientRectangle)

' Left border
If NewPosition.x >= WorkingRect.X - mSnapOffset AndAlso _
NewPosition.x <= WorkingRect.X + mSnapOffset Then
NewPosition.x = WorkingRect.X
End If

' Get screen bounds and taskbar height (when taskbar is horizontal)
Dim ScreenRect As Rectangle = Screen.GetBounds(Screen.PrimaryScreen.Bounds)
Dim TaskbarHeight As Integer = ScreenRect.Height - WorkingRect.Height

' Top border (check if taskbar is on top or bottom via WorkingRect.Y)
If NewPosition.y >= -mSnapOffset AndAlso _
(WorkingRect.Y > 0 AndAlso NewPosition.y <= (TaskbarHeight + mSnapOffset)) OrElse _
(WorkingRect.Y <= 0 AndAlso NewPosition.y <= (mSnapOffset)) Then
If TaskbarHeight > 0 Then
NewPosition.y = WorkingRect.Y ' Horizontal Taskbar
Else
NewPosition.y = 0 ' Vertical Taskbar
End If
End If

' Right border
If NewPosition.x + ClientRect.Width <= WorkingRect.Right + mSnapOffset AndAlso _
NewPosition.x + ClientRect.Width >= WorkingRect.Right - mSnapOffset Then
NewPosition.x = WorkingRect.Right - (ClientRect.Width + SystemInformation.FrameBorderSize.Width)
End If

' Bottom border
If NewPosition.y + ClientRect.Height <= WorkingRect.Bottom + mSnapOffset AndAlso _
NewPosition.y + ClientRect.Height >= WorkingRect.Bottom - mSnapOffset Then
NewPosition.y = WorkingRect.Bottom - (ClientRect.Height + SystemInformation.FrameBorderSize.Height)
End If

' Marshal it back
Runtime.InteropServices.Marshal.StructureToPtr(New Position, LParam, True)
Catch ex As ArgumentException
End Try
End Sub[/highlight]
