I'm making a program and one of my functions needs access to one of the variables (hwnd) in my main function (WinMain). If I keep hwnd in WinMain I get a compilation error because my function can't access the other variable (duh). And then if I set hwnd to be a global variable I get some weird runtime error.

HEAP[Dll Injector.exe]: HEAP: Free Heap block 166df0 modified at 166e04 after it was freed
Windows has triggered a breakpoint in Dll Injector.exe.
This may be due to a corruption of the heap, which indicates a bug in Dll Injector.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while Dll Injector.exe has focus.
The output window may have more diagnostic information.

GetIndexName
| Code: |
void GetIndexName() {
char ExeFile[255];
int index = SendMessage(hList, LB_GETCURSEL, NULL, NULL);
if(index != LB_ERR) {
SendMessage(hList, LB_GETTEXT, (WPARAM)index, (LPARAM)ExeFile);
SetDlgItemText(hwnd, IDC_PROCESS_EDIT, ExeFile);
}
}
|
My global variables
| Code: |
/* Make the class name into a global variable */
char szClassName[ ] = "DllInject";
HWND hList;
HWND hwnd; /* This is the handle for our window */
char path[MAX_PATH];

you still haven't posted your whole code but i think i know the problem. Do it like this.
Make a new global variable
HWND hWND;
In your winmain function,after WM_INITDIALOG or WM_CREATE or just at the start of function, add
hWND = hwnd;(hwnd should be the winmain hwnd parameter/argument).You can use hWND anywhere now  .
Hope it helps.

Thanks STN it's working now. But now I have a weird bug. Basically I'm trying to make it so when you click or double click on a process name in the list box it will list it out in my process name edit box. But the bug is, is that it will do that. But you have to click/double click and then hover your mouse over a button to make it list it o.o Anyone know how to fix this?

Make sure you filter it like this or else any notification the window sends will execute that function.
This was an example from the process list i made for my attempted CE which i gave up on

Now it doesn't do anything. Or am I filtering it wrong?
| Code: |
case WM_NOTIFY:
switch(LOWORD(wParam)) {
case IDC_PROCESS_LIST:
GetIndexName();
break;
}
break;
