Help please [c# windowsforms hotkeys]

err

Code:

[DllImport("user32.dll", SetLastError = true)] public static extern bool RegisterHotKey( IntPtr hWnd, int id, KeyModifiers fsModifiers, Keys vk ); [DllImport("user32.dll", SetLastError = true)] public static extern bool UnregisterHotKey( IntPtr hWnd, int id); const int F11 = 0x0312; protected override void WndProc(ref Message message) { if (message.Msg == F11) { timer1.Enabled = true; } base.WndProc(ref message); } public enum KeyModifiers //enum to call 3rd parameter of RegisterHotKey easily { None = 0, Alt = 1, Control = 2, Shift = 4, Windows = 8 }

im trying to add another hotkey...... F12 but im having trouble i dunno what f12's number is like f11 is

Code:

const int F11 = 0x0312;

what does F12 equal? 0x "here?"

If it is C#

your actually looking for the Virtual Key, same as Vb.net ,

[php]
VK_F12 = 0x7B
[/php]

And someone correct me if I am wrong, but you are following a tut,

The Value you are setting is for a hotkey, not specifically for f11

You could also add

[php]
if (message.Msg == F12)
{
timer1.Enabled = false;
}
[/php]

Because im total noob and google pulls up shit like what i was using but thanks.

Go to your own site.

You shouldn't need anything more then you already have.

So If I am Correct , Your code should look like this

[php]
[DllImport("user32.dll", SetLastError = true)]
public static extern bool RegisterHotKey(

IntPtr hWnd,
int id,
KeyModifiers fsModifiers,
Keys vk
);
[DllImport("user32.dll", SetLastError = true)]
public static extern bool UnregisterHotKey(
IntPtr hWnd,
int id);
// Changed this
const int WM_HOTKEY = 0x0312;

protected override void WndProc(ref Message message)
{
if (message.Msg == F11)
{
timer1.Enabled = true;
}
// added this
if (message.Msg == F12)
{
timer1.Enabled = False;
}

base.WndProc(ref message);
}

public enum KeyModifiers //enum to call 3rd parameter of RegisterHotKey easily
{
None = 0,
Alt = 1,
Control = 2,
Shift = 4,
Windows = 8
}
[/php]

OK thanks...this has helped me greatly..but f12 and f11 arn't called ill try and fix

I VM(ed) you some tutorials on working with Global hot keys in C#, Plus threw in a tutorial on Low Level Keyboard Hooks which should help as well.

Anything else , let me know

Next shouldn't have to look stuff up for you. :l

I always just use GetASyncKeyState() and just plugin the proper keycode. Saves a lot of time. You can call it within C# by importing it:

Code:

[DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true)]
public static extern short GetAsyncKeyState(int vkey);

To be honest though I know they way java works and there is probably a much simpler way. Also you really need to learn how to use Google & MSDN How to trap keystrokes in controls by using Visual C# ... cuz damn.

The good thing is I understand the basic concept of C# because in design and layout it is identical to vb.net , and CSS and some PHP knowledge helps alot.

I am learning Objective C, because I am developing Iphone Apps, and typically I do it with CSS, Java and Html, but I really want to do it in it's native language, so this is good practice.

I wasn't aware. Are C# and Objective-C much alike? All I know is Obj-C is used for all of Apple's stuff.

Objective-C

[php]
MyType *myType = [[MyType alloc] init];
[myType myTypeInstanceMethod:10];
[/php]

C#
[php]
MyType myType = new MyType();
myType.myTypeInstanceMethod(10);
[/php]

Obviously not the same, yet similar enough, not that I need Object C for Iphone applications, You can run a stand alone application built in HTML/CSS/Java or even Flash (not that that's really a good idea, the flash part) and with Html,css,java you can still access every feature of the Iphone/Ipod/Ipad,(Yay WebKit) but it just feels "Cheap" to me, like i should just do it in Objective C,

Objective C looks ugly o__O

Help please [c# windowsforms hotkeys]
