Visual C++ 2003 and Profiler

Previously (ie. VC++ 6), the Profiler was only included in the Professional and Enterprise versions. Is the Profiler included in VC++ 2003 Standard or do you have to purchase Visual Studio Pro 2003 (since it's not possible to purchase VC++ 2003 Professional separately) ?

There's no profiler at all in VS.NET 2003, whatever edition (I have Enterprise Architect here). Microsoft usually links to DevPartner Profiler Community Edition[^].

Hi
Using Win32, you can use FindFirstFile and inspect the WIN32_FIND_DATA structure returned from that (and call FindClose when you leave).

In .NET, that information is available from the FileInfo class.

Why not use GetFileSize()?

The function should take only the constant pointer to the path of the file..

Ok, what's wrong with:

DWORD SizeOfFile( LPCTSTR lpszFile )
{
    DWORD dwSize = 0;
    HANDLE hFile;
 
    hFile = CreateFile(lpszFile, 0, 0, NULL, OPEN_EXISTING, ...);
    if (hFile != INVALID_HANDLE_VALUE)
    {
        dwSize = GetFileSize(hFile, NULL); // you may want to use GetFileSizeEx() instead
        CloseHandle(hFile);
    }
 
    return (dwSize);
}

Try

CFile myFile(lpszFileName, CFile::modeRead);
int len = myFile.GetLength();

Statics in tab pages on WinXP?

Hello!

I've got a property page, containing a tab view. The tab pages are a bit brighter than the normal dialogs, which seems to be correct. But unfortunately all the static controls in this tab page have the standard gray color, i.e. the one of the dialogs and not the one of the tab page.

How can I make the statics look correct?

Best regards

Try setting the static controls' Transparent property to True in the Resource Editor.

Any other ideas?

Thanks and best regards

Oh, btw, it's not only the statics. Also the buttons (edges), checkboxes and radios all look incorrect, all have that darker gray... The only things that look correct are the edit controls and the progress controls...

Best regards

OK
What are you using? VC6, VC7?
Is this Tab control MFC, eg. with CPropertySheet/CPropertyPage.
Is is dynamically created, or just the standard controls dragged from the toolbox onto the dialog in the resource editor?

Does this happen with all tab/property pages on your machine, or just the one in your app?

VC6, it's a MFC project.

I'm not using the CPropertySheet/CPropertyPage classes.

It's just dragged from the toolbox into the dialog, using the resource editor.

I'm handling the click messages on the tabs myself, to display the correct dialogs / dialog elements. I'm not using any third-party classes to do this.

It just happens in my application. In the desktop display properties for example it looks correctly.

Any ideas??

What happens if you create a Dialog-based MFC app using the wizard, with the same controls?

Sorry if this messes you about, but that's just what I would try.

Exactly the same...
- Create new MFC dialog project
- Drag-n-drop a tab view into the dialog
- Drag-n-drop a static onto the tab view
- Add a XP manifest (resource 24/1) to the project and manually add InitCommonControls()
- Build and run

The statics have the wrong background.

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

The problem that you have is that the static controls are taking the background colour of your dialog rather than the tab control. I have gotten around this problem in the past by writing an owner drawn static control.

Here[^] is a good example of an owner drawn static. It may be a bit too much for what you are doing, however you could use it for ideas.

Um, sorry about that, I should have read you post a second time to see that you do indeed mension the other controls.

Since posting Shog9 has posted a reference to an article that will solve your problem.

Have you tried altering the z-order of the controls (i.e. tab order) ?

See this article for a rather complex (but effective) method of correcting this. Then see the comments following the article for several easier methods.

Hi
suspend just pauses the thread.
You'll have to stop it by using an event, with your worker thread looking out for it and elegantly stopping as soon as it becomes signalled. Alternatively you can call Abort on the thread, but make sure the thread handles the exception thrown from this.

That's because the main thread is still running, even though there is no UI.
