NOPing in Visual Basic?

Hey guys im trying to make a hack for a game using blubbs memoryhack dll thingy
But was wondering how would i nop the address?
Example:

Code:

CAHack.SetMemory(&H374B4594, &H90, 6)

Address: &H374B4594
NOP: &H90 (just guessing here)

Length of bytes: 6

Yes it's for CA I enable the checkbox fine as soon as i go to reload CA crashes :\
The addie is no reload btw

Cheers Jàzzà

[php]CAHack.Nop(&H374B4594,6)[/php]

Should work...

EDIT:
I get Access is denied on my 33bit machine
But on my 64bit machine i get no error just CA crashes :|

I also did the "try" function and catched the error but it came up with a whole lot of code, that wasn't necessary

Run VB2010 as admin?

You don't have to, and apparently by what acid_buRn said, that CA deosnt allow access memeory via external programs :\

If your running on Vista or 7 , your application DOES require escalation

I can't speak much to CA, but I can tell you how your OS works

The address you're trying to write to may be in a page with some access rights that you may have to change the write anything.

Use VirtualProtectEx, set the access rights of that page to PAGE_EXECUTE_READWRITE.

I haven't seen that namespace before |:

It's part of Windows API...

[php]
Declare Function VirtualProtectEx Lib "kernel32.dll" (ByVal hProcess As IntPtr, ByVal lpAddress As IntPtr, ByVal dwSize As IntPtr, ByVal newProtect As Integer, ByRef oldProtect As Integer) As Boolean
[/php]

You can remove protections before allocating memory using PAGE_EXECUTE_READWRITE.

I seriously Recommended everyone here takes some time to look into all the platform Invokes.
