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

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

I've tried this, but the static looks exactly the same as before, with the darker gray...

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.

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.

Re: problem with threads

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.

What SW_HIDE is ShowWindow does?

I want to create and drawn to CScrollView that is invisible from the user. Sould I show it using a ShowWindow(SW_HIDE)? Will this permit me to draw on it?

Re: What SW_HIDE is ShowWindow does?

Martin Koorts17-Jan-05 3:22

Martin Koorts

17-Jan-05 3:22

Hi
Yes, the standard CWnd-derived behaviour (such as ShowWindow) will work - you'll have to ensure the focus isn't set to the invisible view if you want the keyboard active, and make sure the window isn't displayed by accident elsewhere, such as a custom OnSize handler, etc.

And yes, I believe you can still process OnPaint, OnDraw messages even if the window is not visible - as you can with most messages. I would just not expect the OS to initiate these (WM_PAINT messages) as the window would not require painting in this state. That said, calling UpdateWindow forces a visit of the paint routine (SendMessage(WM_PAINT, ...) I believe).

Anyway, let me leave you to your devices.... Wink | ;-)

problem with threads

Hi again,

I just started programming with threads and I´m not sure how everything works yet...

Problem: So far I have a 2-threaded Windows Forms Application. When I abort the program by clicking the x-button I cannot recompile the program without restarting my computer. I get an error message saying:
fatal error LNK1104:Cannot open file C:.....program.exe

I guess I have some process running that I didn´t terminate properly.
Though, in the automatically generated "void Dispose" method I placed some code: myThread.suspend();
Isn´t this enough for terminating the thread, or is the problem perhaps somewhere else?

DirectShow - custom StretchBlt

17-Jan-05 2:25

Hi all,

I wonder if there is a way to implement custom StrechBlt to be used by DirectShow?
I need to zoom in a video using pGraphBuilder()->RenderFile() by setting the source and dest. rectangle.
As far as I know the zooming is done using standard GDI StretchBlt function, which gives you the ugly so called "checkerboard"-effect.
