Setting a permanent size to a control

23-Sep-01 9:30

I wanted to know how to set a permanent size to a control.

I have a dialog type application that is set to be 300x400 pixels in size, (the reason I permanently set the dialog box to this size is so that no matter what, if the end user sets their desktop to "Large fonts" the dialog always stays 300x400, I have other reasons too but you probably dont want me to go into them Poke tongue | ;-P

) the problem is that the controls on the dialog box are enlarged. How can I permanently define the size of the controls so they never change?

Thanks
Rob Jones

Well, the coordinates and sizes of controls in .rc resource files are expressed in dialog base units, which are related to the default font size the user has chosen on the "Display Properties" box. This is so by design, and the guys from Microsoft regard it more as a feature rather than a problem. So, if you want to have all the controls back to the positions they should have in what you consider to be "normal font size", just add some code in OnInitDialog() to iterate over all of them and resize them (both position and dimensions) according to the scale factor lNormalDialogBaseUnits/::GetDialogBaseUnits(), where lNormalDialogBaseUnits is the value returned by ::GetDialogBaseUnits() under normal conditions. I'm afraid there's no other way to do it. Good luck.

Thanks for the fast response.. I'm pretty new to VC++, I have found in the .rc file my controls with the dimensions.. And I see the function GetDialogBaseUnits().. I just dont quite understand lNormalDialogBaseUnits .. Is this something I have to create my self? Right now I have in my OnInitalDialog(), GetDialogBaseUnits(); How do I point it to something that holds the demensions I want?

Can you provide me with a small sample of code..

Thanks again for all your help!

What I do is run the app in small fonts, and use Spy++ to get the position and size of all the controls. Then in OnInitDialog(), use SetWindowPos() to position the controls back to those original sizes and positions.
The fonts will still be larger though, so watch out for text that runs off the controls. You may have to mess with the font as well, or shorten any text that's too long in large fonts.

Thanks,
I tried GetDlgItem(IDC_EDIT)->SetWindowPos(NULL,x,y,w,z,NULL);

And everything seems to be ok.. I will take your advice and open spy and get the position and sizes of all the controls and go from there.

Thanks for everyones help.. If anyone still has a different way of doing the same thing I would still like to see other ways Smile | :)

Thanks again!!

I'm afraid I cannot provide you with any consistent piece of code as I don't have a compiler at hand from where I am right now... I assume your problem is that you don't like how your dialog looks like when the user changes the font size of the system. So, set the font size of the system to what you're used to work with and write down the value returned by ::GetDialogBaseUnits(): This is what I call lNormalDialogBaseUnits, and it should be stored in your program as a constant. the ratio lNormalDialogBaseUnits/::GetDialogBaseUnits() is then the factor by which you have to shrink (or expand) controls to bring them back to the positions and sizes you intended in the first place. The code for doing that thus resembles this (be warned I've written this on the fly and chances are it won't even compile):

CWnd* pChildWnd = GetWindow(GW_CHILD);

while (pChildWnd)
{
	CRect windowRect;
	pChildWnd->GetWindowRect(windowRect);

	CString strClass;
	::GetClassName(pChildWnd->m_hWnd, strClass.GetBufferSetLength(32), 31);
	strClass.MakeUpper();
	if(strClass==_T("COMBOBOX"))
	{
		CRect rect;
		pChildWnd->SendMessage(CB_GETDROPPEDCONTROLRECT,0,(LPARAM) &rect);
		windowRect.right = rect.right;
		windowRect.bottom = rect.bottom;
	}

	pWnd->ScreenToClient(windowRect);
	windowRect.left = windowRect.left *  lNormalDialogBaseUnits / ::GetDialogBaseUnits();
	windowRect.right = windowRect.right * lNormalDialogBaseUnits / ::GetDialogBaseUnits();
	windowRect.top = windowRect.top * lNormalDialogBaseUnits / ::GetDialogBaseUnits();
	windowRect.bottom = windowRect.bottom * lNormalDialogBaseUnits / ::GetDialogBaseUnits();
	pChildWnd->MoveWindow(windowRect);
		
	pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT);
}

(The skeleton of this I got it from a Microsoft sample called PRPFONT you can find in the article "PRPFONT - How to Set CPropertySheet Fonts".)

What do I set lNormalDialogBaseUnits to?

For example in the microsoft example they set TEXTMETRIC to lNormalDialogBaseUnits;

Sorry for all the questions.. But thanks for all the help Smile | :)

ActiveX

23-Sep-01 7:25

Hi,

I try to implement an ActiveX that creates a thread (through AfxBeginThread). This thread is calling a custom event. When I try to terminating the thread, it makes an uncaught exception. Even, when I try to communicate from the custom event with the activeX (by testing a property for example), I get a memory problem.

How can I solve these problems ?

Should i use any other method and if yes which one ?

thank you very much for your help.

OnNcPaint()

HI
I hope someone can help me

I want to draw a button left to the [x]-button of a dialog, how can I do this?
I know that I need to use OnNcPaint to achieve this and OnNcHitTest to find out whether the user clicked this button.
But I don't know how to draw at all.

HI ALL

My Code goes a little bit like this:

func1() { func2(); }
func2() { func3(); }
func3() { func4(); }

func6() { <code>throw;</code> }
 
void thread_main_func()

try { func1(); }
catch (...)

}
}

Do I need and how to clear the call stack ?

Sorry, did I forget to specify ? Stroustrup states that try/catch/throw unwinds the stack for you.

I don't know of any way of doing it yourself, actually.
