You need to download the directX9.0 SDK. It has documentation in their for all such things. Specifically look up Directshow, there is an example program called "playwnd" or you may be able to download it seperately. It has code in there for play back video streams, and audio.
But you will need to read the directshow info from the help to understand how to use it. Once you do though its dead easy to create complex multimedia apps.

Hi,
I have following question.
I have created Dialog based application. Now I 'd like to add a chart to the same dialog (simple chart with x and y axis -maybe sth like there is in Windows Task Menager). Is this possible to do in mfc?
Sorry for my English if I made any mistakes :/

There are two ways to handle it. Either you paint the dialog box yourself or use some ActiveX control like the one provided by Microsoft. I think better option is to use the one provided by MS. Right-click on dialog and click InsertControl... This will show you all the registered controls on your system. Use Microsoft Chart Control and this will ease your task.

What is this? Are you wanting to profile your program to find where the bottlenecks are?

Yes, you can move the images to a DLL but then doesn't that DLL become huge, too? You'd also have an extra file to ship. Why does a large EXE bother you?

You might also consider using some form of file compression on the images and then expand them into memory. I have seen VERY large bitmaps compress down to much smaller sizes. You can store the compressed images as RC_DATA and then load them from the resources, then expand them into memory. That would save you some space.

Hi all.
I've written a Visual C++ 6.0 software to calculate the Italian (Codice Fiscale) say that it is like U.S. SSN.
To calculate the C.F. (Codice Fiscale) i use a text file, comma delimited, to find City codes; it works fine.
Now I wander if is possible to embed the text file in the executable to have a compact software made of only one file. Condider that the text file is 247Kb
Thanks to all

I have searched for a way to get the instance handle of the module that my code is executing in.
AfxGetInstanceHandle function available, but only when running as an MFC dll.
GetModuleHadndle is available, but requires the path of the dllm which I don't have.
I cannot inject code in DllMain to "remember" the instance handle because I don't have
access to it.
I have a solution that is quite extensive using "Process Helper", "PE Image Helper" APIs and are quite time consuming. I hope to find a better way of doing it. Probably there exist a way for it, but I haven't found it yet.
Does anybody have a solution for it?

Actually you do. First make a call to GetModuleFileName(...).

No
This function returns the module name of the creating process, not the dll I am executing in.

If you only have to run on Windows XP or Windows 2003 then look at this one GetModuleHandleEx using the GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS flag.
