You want to put the string which is inside a CString object into a TCHAR array of 260 chars? If that's what you mean you could use _tcsncpy like:
_tcsncpy(tchar_array, CString_object, 259);

For Windows Firewall, check INetFwMgr::CurrentProfileType Property[^]. INetFwMgr interface is supported by the HNetCfg.FwMgr COM object. For C++ sample, refer Exercising the Firewall using C++[^]

Hi, I'm trying to add a slider to my program to display the progress of a track when loading a sound file using the MCI functions.

It can seek, but I'm having a few issues.

firstly the slider does not get updated as the song plays, just remains the the same position until u slide it.

When you move the mouse over the position indicator of the slider, the playback jumps back to the position even if the track is currently playing from a different position.

I've been using the following project as an example.

http://www.codeproject.com/KB/audio-video/hmediaplayer.aspx[^]

I've added the timers, and some other things I've noticed from the example code.
Also the example is based on a Dialog class, while mine is a FormView, does that matter?

Thanks
soong

void CUCPView::OnTimer(UINT nIDEvent)
{
	CWinApp* pApp;
	pApp=AfxGetApp();

	if(nIDEvent == ID_TIMER_POSITION)
	{
		lPos = MCIWndGetPosition(m_Audio);
		//c_Slider.SetPos(lPos);
		m_Pos = lPos;
		UpdateData(FALSE);
	}
	CFormView::OnTimer(nIDEvent);
}

void CUCPView::DoDataExchange(CDataExchange* pDX)
{
	CFormView::DoDataExchange(pDX);
	DDX_Control(pDX, IDC_SLIDER1, c_Slider);
	DDX_Slider(pDX, IDC_SLIDER1, m_Pos);
}

Did you try to use SetFileAttributes with directory??
If not try it.
If yes and if it is not working what is the problem?
Did you check error code using GetLastError()??

Hello friends,
I want to convert *.pcx image into *.jpg.
I want to do this conversion using Win32 Application in VC6.0

I am able to segregate the *.pcx header format and store the raw data in BIMAPINFO
strcuture.

But I don't know the header format and raw data requirement of *.jpg format.

I want to convert ICON.pcx file into ICON.jpg file using Win32.

Please give me the suggestion or source code if possible.

Waiting for your positive reply.

CXImage is developed in MFC application. I just want to save *.pcx file into *.jpg
extension file using Win32 not by MFC.

Please give me information about;
How to save one format file into another file format.

Here's a way using GDI+...

#include <gdiplus.h>
...
    BITMAPINFO *pBitmapInfo = ...;
    BYTE *pBitmapPixelBits = ...;
    ULONG dwToken;
    Gdiplus::GdiplusStartupInput input;
    Gdiplus::GdiplusStartupOutput output;
    Gdiplus::Status status = Gdiplus::GdiplusStartup(&dwToken, &input, &output);
    if(status == Gdiplus::Ok)
    {
        Gdiplus::Bitmap bitmap(pBitmapInfo, pBitmapPixelBits);
        CLSID clsid;
        GetEncoderClsid(L"image/jpeg", &clsid);
        bitmap.Save(L"c:\\my.jpg", &clsid);

        Gdiplus::GdiplusShutdown(dwToken);
    }

...

// stolen from the GDI+ docs
int GetEncoderClsid(const WCHAR* format, CLSID* pClsid)
{
    UINT  num = 0;          // number of image encoders
    UINT  size = 0;         // size of the image encoder array in bytes

    ImageCodecInfo* pImageCodecInfo = NULL;

    GetImageEncodersSize(&num, &size);
    if(size == 0)
        return -1;  // Failure

    pImageCodecInfo = (ImageCodecInfo*)(malloc(size));
    if(pImageCodecInfo == NULL)
        return -1;  // Failure

    GetImageEncoders(num, size, pImageCodecInfo);

    for(UINT j = 0; j < num; ++j)
    {
        if( wcscmp(pImageCodecInfo[j].MimeType, format) == 0 )
        {
            *pClsid = pImageCodecInfo[j].Clsid;
            free(pImageCodecInfo);
            return j;  // Success
        }    
    }

    free(pImageCodecInfo);
    return -1;  // Failure
}

If you can use ATL, the CImage class would allow you to do the same in a few lines of code.
