C++ CreateWindow size action

I use : to create a new HWND

But requires the strike code for the window HWND chance his size

ex:
bool HWND (chance size)
{
x = windowX
y= windowY

}

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   HWND hWnd;

   hInst = hInstance; // Store instance handle in our global variable

   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
      CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   if (!hWnd)
   {
      return FALSE;
   }

   ShowWindow(hWnd, nCmdShow);
   UpdateWindow(hWnd);

   return TRUE;
}

Hi Nadir Van Thielen,

you have two possibilities:

1. Just pass wanted position and size of the created window as parameters 4 to 7 when calling CreateWindow
2. Use MoveWindow or SetWindowPos, i.e. just call this before the call to ShowWindow:

 // replace x and y with the dimensions you want to use
 SetWindowPos( hWnd, NULL, 0, 0, x, y, SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE );

Open in new window

Hope this helps,

Oky, i understand more now ,

but what i need is when i resize the from window that the text box change to the max format of the screen.

do i need to make a extra void or bool for it.

wand now is no control over it

   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
      CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   if (!hWnd)
   {
      return FALSE;
   }

   ShowWindow(hWnd, nCmdShow);
   UpdateWindow(hWnd);

   return TRUE;
}
...
...
hwndEdit = CreateWindowExW(WS_EX_CLIENTEDGE, TEXT("Edit"), NULL, WS_CHILD | ES_MULTILINE , 1, 1,800, 400, hWnd, (HMENU) NULL,NULL,NULL );
        ShowWindow(hwndEdit, SW_SHOW);

Open in new window

Ok, so you want to re-size the edit-control in case it's parent window (i.e. a resizable dialog) is resized, right?

If so you have to implement a message handler for WM_SIZE in the parent window, whenever this message is passed to that message handler the passed parameters contain it's client-size which you can use to change the size of the edit control (with SetWindowPos as shown above) - you can find a simple example for such a WM_SIZE message handler i.e. at https://learnwinapi.wordpress.com/2012/01/08/lesson-5-window-message-basics/#packed_arguments.

thank you.

you might consider of splitting points if more than one question helped. my comment actually was intended to be an addition to the solution already posted by ZOPPO.

Yes, Sara, generally I agree, but this time I think it's ok without splitting points, because I had the same thought the other way round at https://www.experts-exchange.com/questions/29044969/C-multi-line-text-box.html where you gave a lot of helpful extra information without recieving any points - so now it's balanced :o)

sarabande

actually it is now 2:1 for me ;-) (i am a perfect counter)
