Dialog in two sizes

[TimoVJL]

I wanted to have a dialog that can maximize to screen.
Let me know other ways to do that.

Code: [Select]

#define WIN32_LEAN_AND_MEAN
#include <windows.h>

#ifndef DLG_MAIN
#define DLG_MAIN 1001
#endif

LRESULT CALLBACK MainDlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);

#define MAXCTRLS 3
RECT aRect[MAXCTRLS]; // normal
RECT aRect2[MAXCTRLS]; // maximized

int __cdecl WinMainCRTStartup(void)
{
HINSTANCE hInstance = GetModuleHandle(NULL);
//int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow)
//{
return DialogBox(hInstance, MAKEINTRESOURCE(DLG_MAIN), NULL, (DLGPROC)MainDlgProc);
}

LRESULT CALLBACK MainDlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_INITDIALOG:
{
RECT rect;
RECT rect2;
GetClientRect(hwndDlg, &rect);
GetClientRect(GetDesktopWindow(), &rect2);
float iAspectRatio = (float)rect2.bottom / (float)rect.bottom;
for (int iC = 0; iC < MAXCTRLS; iC++) {
HWND hWnd = GetDlgItem(hwndDlg, 4001+iC);
GetWindowRect(GetDlgItem(hwndDlg, 4001+iC), &rect);
ScreenToClient(hwndDlg, (POINT*)&rect.left);
ScreenToClient(hWnd, (POINT*)&rect.right);
MoveWindow(GetDlgItem(hwndDlg, 4001+iC), rect.left, rect.top, rect.right, rect.bottom, TRUE);
CopyRect(&aRect[iC], &rect);
aRect2[iC].left = rect.left * iAspectRatio;
aRect2[iC].top = rect.top * iAspectRatio;
aRect2[iC].right = rect.right * iAspectRatio;
aRect2[iC].bottom = rect.bottom * iAspectRatio;
}
}
return TRUE;
case WM_SIZE:
for (int iC = 0; iC < MAXCTRLS; iC++) {
if (wParam == SIZE_MAXIMIZED)
MoveWindow(GetDlgItem(hwndDlg, 4001+iC), aRect2[iC].left, aRect2[iC].top, aRect2[iC].right, aRect2[iC].bottom, TRUE);
else
MoveWindow(GetDlgItem(hwndDlg, 4001+iC), aRect[iC].left, aRect[iC].top, aRect[iC].right, aRect[iC].bottom, TRUE);
}
return TRUE;
case WM_CLOSE:
EndDialog(hwndDlg, 0);
return TRUE;
}
return FALSE;
}
