Resize C++ console Window

Fergal20

Hello there,

Can anyone tell me if its posible to resize the console window in Borland C++ Builder 4 from within the code. I'm trying to make it bigger than the default size.


Thanks in advance.

I don't think you can do that from your code.

I Remember reading about this in one of Mike Blazcksak's books. I don't think there is a simple way; you may be able to kludge it by doing a FindWindow() call using the command window title which will be something like c:\\mydir\\myapp.exe and sending a series of WM_COMMAND messages to emulate the menu items which do the same thing, there may be some other specific windows APIs to do the same thing.

Just curious, why do you want to anyway?

I have to display a graph on the console screen and I want the screen to be bigger!

Hiya,

I use VC++, a little different than Borland C++ 4.0 but it may be done in a similar manner...

This is how you resize the window in VC++

LRESULT CALLBACK WndProc(HWND hWnd,UINT Message,WPARAM wParam,LPARAM lParam)
{
static HDC hDC;
static HGLRC hRC;
int width,height;

switch(Message)
{
case WM_CREATE://create your window
hDC = GetDC(hWnd);
g_HDC = hDC;
SetUpPixelFormat(hDC);
//set up pixel format need to write this yourself

hRC = wglCreateContext(hDC);
wglMakeCurrent(hDC,hRC);
Initialize(); //set up what is in the window

return 0;
break;

case WM_CLOSE://when the window is closed
wglMakeCurrent(hDC,NULL);
wglDeleteContext(hRC);

PostQuitMessage(0);
return 0;
break;

case WM_SIZE:

height = HIWORD(lParam);
width = LOWORD(lParam);

if(height == 0)
height = 1;

return 0;
break;
return(DefWindowProc(hWnd,Message,wParam,lParam));
}

That is for VC++ using a windows application...
I'm sure it is something similar in borland
