I've been trying like crazy to get this stupid PostMessage deal to work.

Here's my code:

Code:

int _tmain(int argc, _TCHAR* argv[])
{
   HWND hHandle = FindWindow(NULL, _T("Untitled - Notepad"));
   cout << hHandle << endl;
   int x = MapVirtualKey(0x5A, 0) << 16;
   cout << x << endl;
   cout << GetLastError() << endl;
   PostMessage(hHandle, 0x100, 0x5A, x);
   cout << GetLastError() << endl;
   Sleep(1000);
   PostMessage(hHandle, 0x101, 0x5A, x);
   return 0;
}


When it runs, it gives me a valid handle, and a valid Virtual Key, and both GetLastError()s return 0. However, when I go check notepad, the text is still the same. What am I doing wrong?

Damn.

Is there an easy way to just send something to the selected control?

I'm trying to loop through running programs and send a key-combination to it. Notepad was just an example.

Code:
HWND hHandle = FindWindow(L"notepad", NULL);


^ You might want to use the class instead of the window title aswell.

Ok, now I never got this.

When using classes in FindWindow, it's referring to classes as things like when you create your own class while programming, right? If so, how do you know the class--do you just kinda know?

Edit:

GetClassName! Surprised

Edit again:

I hate the fact that C++ has no default string. -__-

Ok, so I have this:

Code:

char *cname;
int wee = GetClassName(hHandle, cname, 81);


This gives me the error that it can't convert char * to LPsomething or other.

I tried the L macro that noz mentioned, and VS said that it didn't exist. -__-

Edit once again:

Damn, that's retarded. Changed it to a TCHAR *, and it built fine. -__-

Edit:

I hate this stuff.

When using this code:

Code:

   HWND hHandle = FindWindow(NULL, _T("Untitled - Notepad"));
   cout << hHandle << endl;
   TCHAR *cname = {0};
   int wee = GetClassName(hHandle, cname, 81);
   cout << GetLastError();
   cin.get();


I get the error 998, which VS tells me is

Code:

Invalid access to memory location.

I don't know if you got it already. But here is how it worked for me:
Code:
h := FindWIndow('notepad', nil);
h := FindWindowEx(h, 0, 'edit', 0);

(ye you see delphi though)

There's a great program called WinSpy with which you can easly check for classes or other things in a window. Too bad it's german...Sad

Well the thing is, I'm not having trouble with the API itself, I'm having trouble with the C++. x_x

Thanks though, I'm talking to Renko about it on MSN

I did make one that i saw long time ago at internet.

It's like that one you just posted, just that this one have less features, just the pointer move one it's avalible. Which also tells you the Class.

I will post since i feel like i will not lose nothing.

The Extension 'rar' was deactivated by an board admin, therefore this Attachment is not displayed.
