Posted: Sun Nov 02, 2008 4:29 am Post subject: C++ problem closing

so ive got this code im trying to test out :

Code:

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <commctrl.h>
#include <stdlib.h>

BOOL CALLBACK DlgProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
UNREFERENCED_PARAMETER(lParam);
switch(uMsg)
{
case WM_INITDIALOG:
   DWORD dwStyle = GetWindowLong(hWnd, GWL_EXSTYLE);
dwStyle = dwStyle | WS_EX_LAYERED;
SetWindowLong(hWnd, GWL_EXSTYLE, dwStyle);
SetLayeredWindowAttributes(hWnd, 0, (255 * 70) / 100, LWA_ALPHA);

   return TRUE;

}
return FALSE;
}

void stuff(){
for (;;) {
   Sleep(100);
}
}

int main(void)
{

HINSTANCE hInst = GetModuleHandle(0);
WNDCLASSEX wcex;
ZeroMemory(&wcex, sizeof wcex);
wcex.cbSize = sizeof wcex;
wcex.hbrBackground = (HBRUSH)(COLOR_3DFACE + 1);
wcex.lpszMenuName = 0;

wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = DefWindowProc;
wcex.hInstance = hInst;
wcex.hIcon = LoadIcon(0, (LPCTSTR)IDI_APPLICATION);
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.lpszClassName = L"WndClass0";
RegisterClassEx(&wcex);

HFONT hfont0 = CreateFont(-11, 0, 0, 0, 0, FALSE, FALSE, FALSE, 1, 0, 0, 0, 0, L"Ms Shell Dlg 2");
HWND hwnd = CreateWindowEx(WS_EX_WINDOWEDGE, L"WndClass0", L"Test", WS_VISIBLE | WS_BORDER | WS_CAPTION | WS_DLGFRAME | WS_SYSMENU, 0, 0, 392, 224, 0, 0, hInst, 0);
HWND hCtrl0_0 = CreateWindowEx(0, TRACKBAR_CLASS, 0, WS_VISIBLE | WS_CHILD | WS_TABSTOP | TBS_BOTH | TBS_NOTICKS, 99, 67, 192, 62, hwnd, 0, hInst, 0);
SendMessage(hCtrl0_0, WM_SETFONT, (WPARAM)hfont0, FALSE);

CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)stuff, 0, 0, NULL);
return 0;
}

BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
            )
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
      DisableThreadLibraryCalls(hModule);
      CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)main, hModule, 0, NULL);
      break;
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
      break;
}
return TRUE;
}

and thats all it is

so why does it close the window as soon as it opens

i inject the dll, the window flashes, and then is gone

im guessing theres something really simple ive missed here, anyone know?

I don't see a message loop? Replace the 'CreateThread(..., stuff, ...);' with a normal message loop.

Code:

case WM_CLOSE:
   EndDialog(hWnd, 0);
   return TRUE;

case WM_DESTROY:
   PostQuitMessage(0);
   return TRUE;

Try adding in those cases

Oh lord thats not right at all. I just noticed that your lpfnWndProc = DefWndProc yet you have DlgProc as the message loop. You should set the lpfnWndProc to DlgProc

ok, still doesnt work, not sure why still, now it doesnt show up at all

Code:

#define WIN32_LEAN_AND_MEAN
#include <windows.h>

UNREFERENCED_PARAMETER(lParam);
switch(uMsg)
{
case WM_INITDIALOG:
   //DWORD dwStyle = GetWindowLong(hWnd, GWL_EXSTYLE);
dwStyle = dwStyle | WS_EX_LAYERED;
SetWindowLong(hWnd, GWL_EXSTYLE, dwStyle);
SetLayeredWindowAttributes(hWnd, 0, (255 * 70) / 100, LWA_ALPHA);

   return TRUE;

case WM_CLOSE:
EndDialog(hWnd, 0);
return TRUE;

case WM_DESTROY:
PostQuitMessage(0);
return TRUE;

}
return FALSE;
}

void stuff(){
for (;;) {
   Sleep(100);
}
}

BOOL main()
{
MSG Msg;

HINSTANCE hInst = GetModuleHandle(0);

UpdateWindow( hwnd );

while( GetMessage( &Msg, NULL, 0, 0 ) > 0 )
{

}
return Msg.wParam;
}

What are you trying to do? Are you trying to make something from a dialog? Very confusing... It looks like you're trying to mix dialogs with Win32. You obviously exported the C++ source code from ResEdit so just use that to create your window.

This works for me.

Code:

#define WIN32_LEAN_AND_MEAN

#define ID_CTRL 100

#include <windows.h>
#include <commctrl.h>
#include <tchar.h>

HFONT hFont = CreateFont(-11, 0, 0, 0, 0, FALSE, FALSE, FALSE, 1, 0, 0, 0, 0, L"Ms Shell Dlg 2");
HINSTANCE hInst;
HWND hCtrl;

void stuff()
{
for(;;Sleep(100));
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
DWORD dwStyle = GetWindowLong(hWnd, GWL_EXSTYLE);
UNREFERENCED_PARAMETER(lParam);

switch(uMsg)
{
   case WM_CREATE:
      dwStyle = dwStyle | WS_EX_LAYERED;
      SetWindowLong(hWnd, GWL_EXSTYLE, dwStyle);
      SetLayeredWindowAttributes(hWnd, 0, (255 * 70) / 100, LWA_ALPHA);

      hCtrl = CreateWindowEx(0, TRACKBAR_CLASS, 0, WS_VISIBLE | WS_CHILD | WS_TABSTOP | TBS_BOTH | TBS_NOTICKS, 99, 67, 192, 62, hWnd, (HMENU)ID_CTRL, hInst, 0);
      SendMessage(hCtrl, WM_SETFONT, (WPARAM)hFont, FALSE);
      CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)stuff, 0, 0, NULL);
   break;

   case WM_CLOSE:
      DestroyWindow(hWnd);
   break;

   case WM_DESTROY:
      PostQuitMessage(0);
   break;

   default:
return DefWindowProc(hWnd, uMsg, wParam, lParam);
}

return FALSE;
}

int MainLoop()
{
HWND hWnd;
MSG Msg;
WNDCLASSEX wcex;

ZeroMemory(&wcex, sizeof(wcex));

wcex.cbSize = sizeof(wcex);
wcex.hbrBackground = (HBRUSH)(NULL_BRUSH);
wcex.lpszMenuName = 0;
wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = WndProc;
wcex.hInstance = hInst;
wcex.hIcon = LoadIcon(0, (LPCTSTR)IDI_APPLICATION);
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.lpszClassName = L"WndClass0";

if(!RegisterClassEx(&wcex))
{
   MessageBox(NULL, _T("Class registration failed!"), _T("Error!"), MB_ICONWARNING | MB_OK);
   return 0;
}

hWnd = CreateWindowEx(WS_EX_WINDOWEDGE, L"WndClass0", L"Test", WS_VISIBLE | WS_BORDER | WS_CAPTION | WS_DLGFRAME | WS_SYSMENU, 0, 0, 392, 224, 0, 0, hInst, 0);

if(hWnd == NULL)
{
   MessageBox(NULL, _T("Window creation failed!"), _T("Error!"), MB_ICONWARNING | MB_OK);
}

ShowWindow(hWnd, SW_SHOW);
UpdateWindow(hWnd);

while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
   TranslateMessage(&Msg);
   DispatchMessage(&Msg);
}

return Msg.wParam;
}

BOOL WINAPI DllMain(HMODULE hModule, DWORD dwReason, LPVOID lpReserved)
{
if(dwReason == DLL_PROCESS_ATTACH)
{
   DisableThreadLibraryCalls(hModule);
   CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)MainLoop, hModule, 0, NULL);
}

return TRUE;
}

EDIT:
If you want to add code, say to a button. In your windows procedure add the WM_COMMAND notification. And then a switch statement to wParam. Like so:

Code:

. . .
case WM_COMMAND:
switch(wParam)
{
case CTRL_ID:
//Code here
break;
. . .
}
break;
