I haven't used CWinXPButtonST but I have used CButtonST and it sounds like maybe the button isn't flat (Highlight only works on flat buttons).. You may have to do something like m_bButton.SetFlat(TRUE);...
Hope this helps,

Texts in titles of all windows are getting smaller and smaller when I have the fonts of controls in one window such as buttons and statics changed. I wonder how the operation on this window affulent all the windows on desktop ---- the whole OS, even after this window has exited.
my code is below:
// CDlg is derived from CDialog
BOOL CDlg::OnInitDialog(){
CDialog::OnInitDialog();
// m_button is a child button in CDlg
SetFont(&m_button, "Times New Roman", 12); // see below
m_button.SetFocus();
return false
}
CDlg::SetFont(CWnd* pWnd, char* strFont, int nSize){
CFont font;
LOGFONT logFont;
memset(&logFont, 0, sizeof(logFont));
logFont.lfHeight=-nSize;
logFont.CharSet=DEFAULT_CHARSET;
strcpy((char*)logFont.lfFaceName, strFont);
font.CreateFontIndirect(&logFont);
pWnd->SetFont(&font);
}
Maybe I should have keep the "font" variable until the dialog is ended, but the problem above still exists when I allocate memory from heap (malloc()) for "font" and "logFont". Can you change the fonts of all windows on desktop?

Make CFont a member variable of the dialog class. Fonts will then work. At least they did for me when I had this problem.

Yes, the font variable lifetime should be longer. Just make it a data member of CYourDialog - no need for malloc or new.
LOGFONT is needed only to call CreateFontIndirect. It can be a local variable.
Have no idea why your app changes the systemwide settings - does this happen only if you call CWnd::SetFont?

I have an application that shows a splash screen for 5 seconds, the splash screen is deleted and a dialog box should be shown. The problem I had was that the dialog box would be behind everything else (the edit box inside the dialog would still have focus, which is correct). To solve this, in the OnInitDialog of the dialog I set the window position and size etc and set the first parameter to wndTopMost. This worked up to a point. The dialog is now on top and the cursor is flashing in the edit box where it should, BUT the box itself still doesn't have focus and you have to click on it before you can type in the edit box. Any ideas how to rectify this?
Thanks in advance for any help,
Nick

This is probably a problem with splash screen which is disabling your dialog window. Check if splash calls EnableWindow.

I was actually using the splash class wrongly and putting a line of code in the wrong place (doh), thanks for the help though,

I noticed in various program loops that allocating a buffer with the new operator didn't seem to work each time. I mean it did work but partially, I sometime have partially allocated buffers (?).
This:
char* pBuf = new char[iVariable];
is not safe. When iVariable is a constant, like MAX_PATH it always succeed but not when it has a dynamic value.
I admit, I seldom test if the allocation succeded or not but the buffer is always allocated but not on the entire sequence (?). Maybe doesn't the new operator allocate contiguous memory blocks and then a pointer operation (pBuf++) is not safe ?
Then, I wonder when I should use malloc instead of new to get sure the buffer is allocated ?

malloc() is for C programs, new is for C++ programs. You can never be sure that your allocation succeeds, always check the result! If the allocation succeeds, the memory block is always contiguous and the size you requested.

malloc() is for C programs, new is for C++ programs.
This is too strict. One can safely use malloc/free in C++ program. Just don't mix malloc with delete and new wih free
- what was allocated with new should be deallocated with delete, malloc() should be accompanied by free().

char* pBuf = new char[iVariable];
is safe, at least when iVariable is correctly initialized. If iVariable contains bogus bits, the buffer size may be too large to fit on the heap. In such case, operator new fails and returns NULL on VC6 or throws bad_alloc exception on standard-conforming compilers.
the buffer is always allocated but not on the entire sequence (?).
I don't understand what do you mean.
Maybe doesn't the new operator allocate contiguous memory blocks
It allocates contiguos block of size passed in iVariable.

Hi, thank you all for replying.
the buffer is always allocated but not on the entire sequence (?).
I mean that I was reading a file buffer and I read the beginning of the buffer but the buffer is empty before the end of it, so I suppose it was partially initialized.

I found out the problem: iVariable ;((
I used the size of another -smaller- disk file (i used it to load a file buffer in memory). The "smaller" makes all difference and actually did the partial buffer load that I noticed.
Anyway, I'm now sure that new and malloc have the same usage and that they both create contiguous memory buffer.
Sorry and thanks  )

In OLE/COM Object viewer My object present in the folder : Automation Objects but if I try open it by press on the + , I gets the messageBox:
------------------------
CoGetClassObject failed
class not registered
REGDB_E_CLASSNOTREG(..)
------------------------
I try to register it again by: regsvr32 <dll filename="">
but I get error message that the LoadLibrary failed .
(the path is clearly ok !).
What can I do ?

According to MSDN
Q. What are the reasons an ATL server might fail to register?
The following also applies to ATL 3.0:
A. The following are the top three reasons an ATL server might fail to register:
You built your project with _WIN32_WINNT=0x400 (the default), and you are not running the ATL server under Windows NT 4.0 or you do not have an up-to-date version of Oleaut32.dll. To solve this problem, run "DUMPBIN /EXPORTS OLEAUT32.DLL" and search for UnregisterTypelib. If it is not there, then your server cannot run. Remove this #define statement from Stdafx.h if you want to run the ATL server under Windows 95 or older versions of Windows NT. Alternatively, you can use LoadLibrary and GetProcAddress so that you can run optimally under both Windows 95 and Windows NT 4.0. The Oleaut32.dll that ships with the Internet Explorer 3.x is up-to-date.
You built your project as MinSize and Atl.dll is not properly installed on the system. The correct version of Atl.dll must be copied and registered by Regsvr32. There are Windows NT and Windows 95 versions of Atl.dll. The Windows 95 version runs under Windows NT. However, since it does not use the UNICODE APIs, it is slightly less efficient. Unless you build your project as MinDependency, you will need to install the correct version of Atl.dll and run Regsvr32 on it before you install your server.
You built your project as UNICODE, and you cannot run it under Windows 95.
The following are the steps to troubleshoot:
For a DLL server, run Regsvr32 in the debugger. Open the Project Settings dialog box and click the Debug tab. In the Executable for debug session text box, enter the full path to Regsvr32.exe, such as C:\Sharedide\Bin\Regsvr32.exe. In the Program arguments text box, specify the full path to your DLL, such as C:\Myprojects\MyFolder\Debug\MyFile.dll. Set a breakpoint at DllRegisterServer and start stepping.
For an EXE server, run it in the debugger and specify /REGSVR as its command-line argument.
I suggest if you need to ask this question again tomorrow you try to provide some more information, because it's obvious based on what you're asking that either you're not providing enough info, or you have got the right answers and want to hear something else. Have you got your books yet ?

thank you ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
So this is what I understant from all this :
*For the DLL server*
-----------------------
Open the Project Settings -Debug tab.
In the Executable for debug session text box, enter the path to Regsvr32.exe and In the Program arguments text box, specify the full path to my DLL.
Is that all ?

To be honest I opened MSDN and looked for something that sounded helpful. What the above is going to do is pass the dll path as the argument to RegSrv32, it's the same as navigating to the dll path and typing regsrv32 mydll.dll in the console.
If you don't have access to MSDN, try msdn.microsoft.com, there are a lot of articles that matched my search, you might find something more helpful there.

I tried it and I gets again the errorMessage that it failed !
I dont understand where exactly I have put a breakpoint (What means "at DllRegisterServer" ???)
|
|
|
|

If you don't have a dllRegisterServer function, then RegSrv32 is obviously not going to work.

What compile option have you used for your ATL DLL? Is it Min-Dependencys or Min-Size?
Michael

Can you explain me what means Min-Dependencys or Min-Size ?
I simply compile with f5 ,f7, ctlf7
|
|
|
|

When you choose the configuration to compile, you can choose minimum dependancy or minimum size. What they mean is a no brainer - one compiles to include all the code it needs, the other leaves out whatever it can to keep the size down. I believe this function is one you loose in min size, because there are other ways to register, but the details escapec me.
Mimi, if you logged in I would have got an email telling me you responded to my comment and I would have been able to reply sooner. Not that the other comment is no good, chances are he knows more about it than me, but I'm trying to point out the benefits of logging in. After two weeks of the same questions we all know it's you, so if you were hoping to be anonymous, you'll have to ask about something else ;0)
