Am not sure i completely understand what you are trying to do but check out this[^], if i am correct than it should help (you will need ON_WM_CTLCOLOR_REFLECT for your case i belive). Good luck.

Hi,
I have a problem in resolving the issue of GetFont() used in dialog box class for getting font but its returning NULL in one of the dialog class but its working in all the other dialog box classes.. The error comes in using the getlogfont() function where it crashes.. What could be the problem as it works fine in other dialog classes ... ?? please reply soon ...

the code which i am using is
CWnd* p_Wnd;
CFont* pFont;
pFont = p_Wnd->GetFont();
LOGFONT m_lFontBold;
pFont->GetLogFont(&m_lFontBold);
I am getting error in getlogfont in debugging mode. As far my understanding the getfont() isn't returning the handle to the object that is why there is an assertion problem in getlogfont(). But the same code is working properly in different dialog boxes.

pleaz use a valid CWnd* p_Wnd...
p_Wnd = this;
Press F1 for help or google it.

If you check the documentation[^] for WM_GETFONT (CDialog's GetFont is a wrapper around that), a NULL value means your dialog is using the system font. Otherwise, if you are not testing this in debug mode (so you don't get a debug assert) then you simply get a NULL back if you call GetFont on a dialog that has not been created, as far as i know at least. (Ok, if you run it in debug you still get the NULL back if your dialog wasn't created, but you would also get a DEBUG ASSERT FAILED notification...)

In the code you have shown you never initialize p_Wnd to anything...but i will assume that in the actual code segment you do. So what is the difference between this dialog and the others? How do you create it? When/Where do you ask for its font?

I am using this code in oninitdialog function to set up the bold font on initialization of dialog. There is no difference in other dialog boxes and this one for setting up the fonts. I havent initialized the pWnd in this code and in any other initdialog functions but still that works.

I have attached the control of dialog box to the cwnd object using getdlgitem()..
|
|
|
|
|
So you say you call GetFont thorough an uninitialized pointer and it works???? That doesn't sound normal...

hey i have initialized the cwnd object by passing the control of the dialog box static text using getdlgitem() function
|
|
|
|

And you did the same thing in all your dialogs, retrieve the handle of a static on the dialog in OnInitDialog, attach a CWnd to it, call GetFont on it, and it gave you a valid CFont pointer except for this one, identically implemented dialog? Can't think of anything smart, sorry...maybe someone else has a better response then.

hey after doing some research work .. This problem is changed to the static text only.. The problem seems to work on the button controls but when i use static text for the cwnd object initialization to get the font then it crashes in the getlogfont function... so give me some insight for this....

My guesses are as follows:
-since the documentation for WM_GETFONT says that a NULL return value means the control is using the system font, a NULL from the static control must mean it is using the system font.
-possible that the static control will use the font of its parent window to draw text unless it gets a different font explicitly set to it via WM_SETFONT, and that is why you get the NULL back, meaning that the static doesn't have its own font set, it will use its parent's.

so why is it working for the button control and not for the static text control... and also this static text control thing do work in different dialog classes.. and I havent explicitly called the WM_getfont for those classes....

-because of their different implementation i supose

-CWnd::GetFont(), which is inherited by the CDialog, is just a wrapper around WM_GETFONT, if you call it, WM_GETFONT is sent to the control, and on the handle it returns CFont::FromHandle is called, you can check that yourself if you take a peek at CWnd::SetFont's implementation (try right-clicking it in visual studio and select "Go to definition" or somesuch)

Hi All
How to Convert character to other character like german,dutch etc. which user can change a language during run-time, for example, selecting it from menu.Can any one help me

I think there is no easy method to do this. You have to store each language strings separately and use them based on the language selection from menu.

There is no nay dll for this work.

Sorry. No

It's not clear exactly what you mean. I sounds like you might want to add the ability to change the language of you application dynamically at runtime, but this is only a guess.
