<p>I have an MFC app which I have been working on for a few weeks now, I want to manually set the dimensions of the main frame when it is loaded, can someone give me a hand with this, specifically where to put the code as well?</p>

<p>Thanks!</p>

Find your screen size with ..
```
```
CRect rect;
SystemParametersInfo(SPI_GETWORKAREA,0,&rect,0);
screen_x_size=rect.Width();  
screen_y_size=rect.Height();
```
```
use these values to calculate the X and Y size of your window then ..
```
```
::SetWindowPos(m_hWnd,HWND_TOPMOST,0,0,main_x_size,main_y_size,SWP_NOZORDER);
```
```
Where
```
main_x_size
```
and
```
main_y_size
```
are your sizes.
