  • how to add text in external .rtf file
    C Chiew Heng Wah

    I suggest accessing the RTF file using MS Word COM APIs (if available)and to use the same MS Word COM API to save the file as RTF again after you made your modifications. MSDN has a link to the RTF specification http://msdn.microsoft.com/en-us/library/aa140277(office.10).aspx, but you might want to avoid this method as it is very tedious.

  • How can I free memory before returning the value in my function?
    C Chiew Heng Wah

    You could declare it as a global variable, outside the function instead: char ReturnArray[1024] = {0}; // put it here. char *rr(char*s) { char cc[4] = {0x00,0x00,0x00,0x00}; // char ReturnArray[1024] = {0}; // move it up instead.

  • Regarding web page content
    C Chiew Heng Wah

    Assumming the COleContainer implements a IHTMLDocument interface you will then be able to get the HTMLElement of the Body of the webpage. The HTMLElement class has many different methods for you to access the text of the webpage. If you want the HTML use the InnerHTML method, if you want the plain text, use the InnerText. There is also the corresponding OuterHTML and OuterText - depends on what you are looking for.

  • Hello all I want to capture an image from a Camera
    C Chiew Heng Wah

    Can I safely assume you are talking about a web-camera (webcam)? The DirectShow examples in DirectX SDK should work with the web-cam. Codes are included. Heng Wah.

  • Hello all I want to capture an image from a Camera
    C Chiew Heng Wah

    Try the following CodeProject article by Blas5 Title: Capture Sample with DirectX and .NET Link: http://www.codeproject.com/directx/CapSample1.asp You should also read DirectShow documentation. Also DirectX SDK has a sample program called StillCap.exe under <DXSDK Directory>\samples\Multimedia\DirectShow\bin

  • DirectShow (DirectX)
    C Chiew Heng Wah

    The Windows Media 9 Series SDK provides a number of methods to read/write/edit. Perhaps you want to have a look at Windows Media Format SDK from the following site: http://www.microsoft.com/windows/windowsmedia/9series/sdk.aspx It's not DirectShow but it's significantly smaller in size compared to the DirectX download.

(the instances may be owned by other applications).:confused: If so, is there a way to interface with these created COM objects of another application?:~ Thanking in advance for a reply.:-D

  • Capturing Video Surface
    C Chiew Heng Wah

    I can screen capture a window surface. But not a video surface being played on Media Player. I get only the frame of the Media Player and a "black" surface where the current video frame should be. This "black" surface is seeming like a "transparent" layer (I am guessing here) upon which the video frames are rendered. I am guessing it is the DirectShow surface. How can I capture the video frame?:confused:
