I wrote below function in VC6 one year ago, maybe it can give you some hints.

BOOL CMyClass::CaptureImage(LPCSTR szFileName)
{
if (pVMRWindowlessControl== NULL)
return FALSE;

BYTE* lpImage = NULL;
if (pVMRWindowlessControl->GetCurrentImage(&lpImage) == S_OK)
{
BITMAPFILEHEADER hdr;
DWORD dwSize, dwWritten;
LPBITMAPINFOHEADER pDib = (LPBITMAPINFOHEADER)lpImage;

//创建文件供写入
HANDLE hFile = CreateFile(szFileName, GENERIC_WRITE, FILE_SHARE_READ,
NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);

if (hFile == INVALID_HANDLE_VALUE)
return FALSE;

//初始化BITMAP文件头
dwSize = DibSizeImage(pDib);
hdr.bfType = BFT_BITMAP;
hdr.bfSize = dwSize + sizeof(BITMAPFILEHEADER);
hdr.bfReserved1 = 0;
hdr.bfReserved2 = 0;
hdr.bfOffBits = (DWORD)sizeof(BITMAPFILEHEADER) + pDib->biSize + DibPaletteSize(pDib);

//写入文件头及内容
WriteFile(hFile, (LPCVOID)&hdr, sizeof(BITMAPFILEHEADER), &dwWritten, 0);
WriteFile(hFile, (LPCVOID)pDib, dwSize, &dwWritten, 0);

CloseHandle(hFile);
CoTaskMemFree(lpImage);

}

return TRUE;

}

I am using WinExec() function in a project. The WinExec function runs the specified application.

Example:
WinExec("notepad.exe",SW_NORMAL);

But i want to run Internet Explorer in WinExec(). In each and every system Internet Explorer will not be installed in same path. So, i want to know is there other way except by giving actual path..

Regards.

It is not neccessary that on every machine IE has been installed. It may be possible that user is having the other browser (mozilla, Netscape, etc) instead of IE. So, how are you handling this situation, just for curiosity.

I believe that:

WinExec("iexplore.exe",SW_NORMAL);

will execute Internet Explorer.. As IE is usually pre-installed with Windows, it is often recognised as a command line function..

For example, opening up the "Run" box in windows (Windows key+R) and typing in "iexplore.exe", Internet Explorer WILL run.

Hope this helps!

I tried this.

WinExec("iexplorer.exe",SW_NORMAL);

Cry | :((

Bus it is not working.

Because IE is not istalled in Windows Directory. In my system, it is in "C:\WINDOWS\ie7\iexplorer.exe". It is about the version also. We can`t say it is constant in all the system. So there must be other solution.

Thanks and Regards.

Hi,

The question is what do you want to achieve? Do you just want to open a browser window (user default browser or specifically IE?) or do you want to display a web site.

You should also take ShellExecute into consideration. This method allows you to also open a website using the default browser or IE directly and it shouldn't matter where your browser is installed.

Hope this helps.

Best regards

ShellExecute(NULL,"open","about:blank",NULL,NULL,SW_SHOW);

or

keybd_event(0xac,0,0,0);
keybd_event(0xac,0,KEYEVENTF_KEYUP,0);

But did you see MSDN about this function,of the MSDN

You can either let the OS decide which browser to open by calling ShellExecute() with the name of the HTML file you want to open, or you can call FindExecutable() (or AssocQueryString()) to get the full path of the associated application.

I can't get the pin category property in my directshow program, I try all pins in all filters(pSrcFilter, pMux, pMpeg2Splitter, pDecoder, etc), but every pin can't query the IKsPropertySet, it alawys return fail, so i can't know that the pin category is PIN_CATEGORY_CAPTURE or PIN_CATEGORY_PREVIEW, why? please give me some suggestion.

IKsPropertySet *pKs;
hr = pPin->QueryInterface(IID_IKsPropertySet, (void **)&pKs);
if (FAILED(hr))
{
return FALSE;
}

For pins, you'll mainly find the IKsPropertySet interface on capture filter pins.

Here's some sample code that may help:

the merit of it is 0x800200.
when I render a mediafile using graphedit,it is loaded.
But when I use Mediaplayer,it can't be loaded autoly.
