Hi!!
I have a problem and I'm not founding the solution..

I send a fax via Office Outlook from a vc++ program.
My problem is that if I send it with a profile that hasn't got the coversheet, outlook puts however a white page before my fax only with the line "Subject:...".

I think that I ought to set a mapi property, but I have no idea of what!!

thank you

How do I know which font is used in dialog box

I would expect that if I use:
CClientDC dc(this);
inside the code for a dialog box it would pick up the font used for that dialog box. In fact, it doesn't. I had to add:

currFont.CreatePointFont(80, "MS Sans Serif", &dc);
oldFont = dc.SelectObject(&currFont);

and then it measured the text extent correctly. (I got the font name and size from the dialog template.)
Clearly, it won't change unless I change it in the project, but I am curious to know how to pick up the information "automatically".

Any suggestions? Thanks,
Ilan

Thanks. I didn't think it was that simple.
It must be internally this.GetFont(), otherwise I don't know how it could figure out which font I want.

In any case, it works....

You are right - CWnd::GetFont() returns current font for window. This font is not selected automatically in compatible DC on creation.

As an aside, i ran into this earlier this week in a WinCE (PocketPC 2002) app i was working on.
I found that calling CWnd::GetFont() for a CDialog window always returned NULL.

Turns out this is expected (from MSDN WM_GETFONT for WinCE):
The WM_GETFONT message does not return a font handle if the message is sent to a dialog box created by the DialogBoxParam, DialogBoxIndirectParam, CreateDialogParam, or CreateDialogIndirectParam functions.

Exception occurs when dynamically creating control

Hi,
I have derived a class from the CEdit and overided the function PreSubclassWindow(). Inside this function, I called the SetFont function.

The control works fine if this class is made as the control varaible type. But when I Created a object and called Create() function it throws exception

I found its because of the SetFont in PreSubclassWindow.

Is there any way to get ride of this?
or
Is there any function/message for Edit box(other than PreSubclassWindow)where i could do initialization after the window is created?

Plz help
Thanks in advance

We will not get this message while if we create a memeber variable for a control( While creating memeber variable it internally calls SubCalssWindow).

Thank u nibu but did u followed the step below?

1)Create a dialog based application
2) Derive a class from CEdit say MyEdit
3)In the MyEdit::PreSubclassWindow(), set the font.
4)Place button in the dialog and add function for it say OnButton1().
5) inside OnButton1, write
MyEdit *pEdit = new MyEdit;
PEdit->Create(WS_CHILD|WS_VISIBLE,CRect(0,0,100,100),this,1); // here the exception occurs

Yeah you are right...

Try this...

1. Create a registered windows message...

2. Now use PostMessage(not SendMessage) to generate this message...

3. Now inside the handler for this message write the required
initialization code.

Thanks to Nishant

You should do this inside PreSubClassWindow().

ya currently i have implemented this technique. But this message arrive after the WM_SHOW message has arrived. So some times we can see the font changings( i.e The edit control becomes visbile with actual font and the suddenly it font change.)

Thanks nibu

If it is within a dialogue use the OnInit function.

Change the subsystem to WINDOWS.

This is how we change it...

Project
--Project Properties
---Configuration Properties
----Linker
-----System
------SubSystem -->Change this to Windows (/SUBSYSTEM:WINDOWS)

Can you modify WinMain to _tWinMain

int APIENTRY _tWinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow
)
{}

This happens because of UNICODE compilation...

Did you make sure you included the appropriate files into your solution? You can get linker errors if you happen to forget to include the appropriate files (to your solution,) or if you forget to add the appropriate libraries to the properties tab in your project. Make sure those are correct since that has caused me some time in debugging.
