Re: How to extract each column within the data file after reading ????????? Please Help

If you're using MFC then have a look at CString::Tokenize [^] method. On the other hand, without MFC, strtok [^] maybe the way to go.

If you are using MFC, have you looked at AfxExtractSubString()?

I wish to capture some live video and preview, but PlayVideoCap example that i downloaded from Windows SDK, (DirectX) just doesn't do the job. It compiles and there is no error messages. video preview show black screen,although avi frame capturing works fine.. and video capture with VideoCap works. I wish to capture from the Capture Card as well and currently using a surveillance camera.

I am beginner in video programming C++. What possibilities of mistakes there may be? Any advice please! Any other sample codes??

Cheers,
kel

any help will be appreciated.

How to pass enum variable?

How do I pass parameter to member function from main()

class test
{
public:

typedef enum
{ FileModeText,
FileModeBinary
}FileMode;

void func(FileMode);
};

int main(int argc, char* argv[])
{
test tst;
tst.func(..)/*how do I pass here fo type enum.I would like to pass FileModeText as parameter*/
return 0;
}

Somethign like:

test::FileMode fMode = test::FileModeTest;<br />
tst.func( fMode );

should work. What exactly is the problem, compiler error, you're getting?

Hi, Thanks for your quick answer. I tried same. Now I tried with your solution. Still it is not working.I am getting following error:

error LNK2001: unresolved external symbol "public: void __thiscall test::func(enum test::FileMode)" (?func@test@@QAEXW4FileMode@1@@Z)
Debug/single.exe : fatal error LNK1120: 1 unresolved externals

There is no definition of test::func in posted code (there is only its declaration). Did you forget it?

SRKSHOME24-Jul-08 2:18

24-Jul-08 2:18

Oh! Yes.Thanks. It is working now.

You are welcome

This is telling you that the Linker can't find the implementation of test::func( test::FileMode ); the function you're trying to call. T
he simple cause of this might be that you haven't actually written it yet, more complex possible causes include that it exists somewhere the linker can't find it or the linkers incremental stupidity counter has wrapped around its 16bit vlaue limit and you just need to give it a good kicking and make it try again.

No macro that I know of but Google up "doxygen" and you will soon be able to do what you require.

Did you read posting guidelines?
For instance:

Check out this wikipedia link: Comparison of instant messaging clients[^]. There are a number of open source applications in the list. You may want to pick up one, study how it is done and then start doing yours. But trust me, this would actually be more difficult than you think it could be. Good luck with the development.
