The order should be: waveInStop waveInReset waveInUnprepareHeader (for all buffers) And get rid of the Sleep() calls. There is absolutely NO reason for them. When you prepare the headers, you must initialize dwFlags (Use 0 for input buffers) as well as lpData and dwBufferLength. Also, IMO, "headersend + i" is confusing to read. I'd use "&headersend[i]".

A program written using /clr should run on any computer with .Net framework installed. Make sure that 1. The program in 100% .Net /clr then you can just install dotnetfx 2. Also check which version of .net are you targeting 3. If you are doing a mixed assembly, make sure you deploy appropriate CRT/OpenMP/ etc DLLs as well, you can distribute using vcredist.exe or MSMs. 4. And finally, you need to distribute applications built in Release mode not Debug mode. Debug DLLs cannot be distributed.

yes, I only need the message map in MFC. I want to use MFC in windows form application, not use windows form controls in MFC. Appreciate ur reply. Thx. jane -- modified at 0:46 Monday 12th November, 2007

You must ask on the (Managed) C++/CLI[^].

Jane, please note: 1. C++ and C++/CLI are case-sensitive. 2. C++ and C++/CLI classes are private by default. 3. Your CParams class is not int the p2pport namespace 4. Please use more descriptive subject line. 5. Don't disregard Mike's comments. -- modified at 19:49 Wednesday 7th November, 2007 "We make a living by what we get, we make a life by what we give." --Winston Churchill

I dont say that you can not, I made it in header with member variables and in code with the local variables. I have given you an example of that error code and the meaning. I don't think just putting the MyClass* pMC; in your Dlg.cpp will solve it. Although you can try it as well. I think is more a question about the scope and how the relationships between classes are done. Your code is not recognising the other class, there is a point where the connections break. Greetings. -------- M.D.V. If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you ;)

OK. THx.

Outstanding :) Great that it works for you :)

I see. Thx for ur reply.

I move the code in mythread.cpp to mythread.h. Then it works. I think I had the problem before just because I dont understand how to create my own header file completely. -- modified at 6:43 Thursday 25th October, 2007

There is no problem@@. It works.

You're welcome.;)

If you just launched Visual Studio and started coding then that's why you are confused. There are articles here on Code Project[^] and on MSDN that introduce managed/native issues to developers. I strongly suggest your read them. If you have read some and are still confused you should reference the article and the section that you are confused about.

I'd recommend using sprintf or ( better ) ostringstream to do this. That would also make all your code C++, instead of the one reference to the .NET libraries. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog

Yup. System::String is a Managed C++ string, while std::string is an STL string. You need a way of getting the contents of the first in a format that the STL string operator(s) can understand. You'd do better asking in the Managed C++ forum, I think. Steve S Developer for hire

Microsoft's WAV file format is well documented. A quick GOOGLEY search found this one WaveFormat[^] By the way, FCC() is just somebody's function for dealing with FOURCC codes - four characters which need to be written in order in a big-endian/little-endian integer world. Mark
