Hi.
In my app I have an button which is owner draw. The strange thing is happening I can't set it's font?
NONCLIENTMETRICS ncm;
ncm.cbSize = sizeof(NONCLIENTMETRICS);
SystemParametersInfo(SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS), &ncm, 0);
MaliFont.CreateFontIndirect(&ncm.lfMessageFont);
m_Graph.SetFont(&MaliFont);
MaliFont is an CFont member variable.
m_Graph is my button.
To be honest Button ctrl is only a base for my graph ctrl I'm displaying. There is no way I can set font using that graph ctrl, I thought I can set it using base class (CButton).
???

If your button is owner draw then you have to draw it yourself: I suppose it doesn't make sense changing its font via CButton::SetFont.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi and thanks for yours replay!
My CButton ctrl is owner drown! How do You think I should set/create/draw font?
Thanks again.

Well, are you getting any errors along the way?
does the ncm block get filled with sensible values?
Is MaliFont getting a good m_hFont?
And (my suspicion) is MaliFont created only on the stack in the member function you are cutting and pasting code from? If so, its destructor will be called, destroying the font before the button control even tries to use it...
Maybe make it a member object of some dialog class that contains the m_Graph object?
Iain.
Edit:
Or C Pallini is correct and you're not using GetFont in your owner draw routines to actually USE the font you set...

Well, my guess was a possibility too!
I'd have bowed down before your magnificence [*] if I'd seen your post before making mine.

Rude? Why rude? It's my title, after all.

Thanks to all for posting.
The answers:
1. I'm not getting any errors, code execute correctly only the font doesn't change!
2. nmc is filled with sensible values.
3. MaliFont is an member variable of my dialog class('OnInitDialog()'), not created in the member function.
Thanks again guys

In your first post you say this button is owner draw. If so, and you are drawing it yourself, then it is up to *you* to draw with a changed font.
Try turning off the owner draw stuff, and using setfont as previously described. If that works, then the problem is in your owner draw code.
Or maybe you're forgetting to do:
pOldFont = pDC->SelectObject (&MaliFont);
pDC->DrawText (...);
pDC->SelectObject (pOldFont);
(or similar) in your drawing code.

I have complied an application with Visual Studio 2003. It works well with 32 bit os on a 32 bit machine.
But it crashes when run on Vista 32 bit os on a 64 bit machine.
Any clues on how we can debug our application on Vista 32 bit. (As we cannot install Visual Studio 2003 on Vista).
Any help on this is highly appreciated

The problem might be due to UAC. Turn off UAC[^] and try to debug.

Jijo.

Debugging Tools for Windows[^].
This includes WinDbg (which in many ways has a better debugger than VS). Build your app with debug information (either in Release or Debug mode - you can have debug info in either - Release/Debug really implies 'Optimised' or 'Not optimised'!) then run using WinDbg.
The UI is pretty good, having most of the debug & source windows that VS has.
HTH!!

I am writting idl file for my project. It is not allowing me to use FILETIME. if I include the windows.h , then it gives me the compiling error like:
1>C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\winnt.h(280) : error MIDL2003 : redefinition : INT
1>C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\winnt.h(684) : error MIDL2003 : redefinition : Int64ShllMod32
1>C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\winnt.h(684) : error MIDL2025 : syntax error : expecting ; near "{"
1>C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\winnt.h(686) : error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation
If i am not including windows.h , compiler giving me the error:
1>.\TestRPC.idl(178) : error MIDL2025 : syntax error : expecting a type specification near "FILETIME"
1>.\TestRPC.idl(178) : error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation
can anyone tell me how can i resolve this error ?
Thanks

Hi Vijay_k,
it's hard to answer this without looking at your code, but is sounds like you are missing a #pragma once or #ifdef...

I'm not surprised - header files can't always be #include'd into IDL files. You could try...
- Copy & paste the definition of
FILETIME into your IDL file. - FILETIME is really just a 64-bit integer (but defined using a struct because Microsoft C didn't used to have 64 bit integers. IIRC). So, just use an IDL 64 bit integer - I think that's called a
hyper? You could then convert to and from FILETIME when calling the functions defined in your IDL.

Hi
I have an MDI application developed in VC++. We make a build using Install Shield. We are installing build on XP m/c on client sites. The build gets install properly. But while running on some m/c one of my application (this does injetction in processes) is crashing. But the same is running fine on other m/c.
Can anybody provide any suggestion on this.
Thanks

Find out where / why it is crashing?
What is the difference in the eco system?
Does it not run at all, or does it only crash when you do something?
What is that thing? Does it depend on network settings? etc.
Have a look at www.sysinternals.com (redirects somewhere on msdn) and dig up debugview. Then litter your suspect code with OutputDebugStrings to
narrow down your search.
Or you could build your release code with symbols (should be able to google this) and use remote debugging to catch the crash in action.
Iain.

Thanks for you reply. It was a problem of anti virus. we have uninstalled anti virus and it runs properly. It was giving "R-6025 pure virtual function call" error and crashing. Can pls let me know how any anti virus creates problem to any application.

Hi All
I have a Application which have two dialog.I am calling login dialog on Main dialog in OnInitDialog().It's running Successfully.My Dialog application is running in background.when i click on exe of application then login dialog is open.But problem is when i click on Cancel button of login windows(i am useing this function on cancel button OnCancel()) then my main dialog is open.Then i try to write exit()in Cancel button then application is closed.
I want to set option like this,when i use cancel button then only login windows will close.No effect on main dialog.
Plz help me

Then don't bring your login dialog up from your main dialog's OnInitDialog, do that BEFORE you even try to bring up your main dialog. As far as i know if you use DoModal to display a dialog it will be shown after OnInitDialog (and i guess some other message handlers) has exited.

Thanks for reply
i am also try to use in .cpp file before CWinApp::InitInstance(); but result is same.If give me some tips to solve that problem.Thanks in advance

Let me get this straight. What you want is that your main dialog is created, and IF your login dialog is closed with OK, you want your main dialog to appear on screen, but if it is closed with CANCEL you want your main dialog to still exist BUT not be shown on the screen?

You can call EndDialog() and return immediately from OnInitDialog(), instead of calling exit()

|
|

Can you describe me with some example? I am calling login dailog on like this
Clogin dlg;
dlg.domodal();
OnInitDialog.
Plz help me
|
|
|
|
|
Like this, if my understandings are correct... 
BOOL CMainDlg::OnInitDialog()
{
CDialog::OnInitDialog();
...
...
CLogin dlg;
if( dlg.DoModal() == IDCANCEL )
{
EndDilaog( 0 );
return FALSE;
}
...
}
