thanks for your reply....
i tried changing the runtime libary to Multi threaded Debug /MTd but of no use .....

In that case it looks like it might me an include path issue. I still think it odd that this STL code which is distributed as source seems to be requiring the definition of a C Runtime function that isn't part of the standard interface in order to compile. Something subtle/nasty is going on here. Are you trying to mix code from VC6 with VS2002 or later? Do you have the C Runtime source installed with your compiler (it's optional)? I'd start by checking where your build is pulling its STL and CRT header files from. Perhaps one is coming from a much later SDK and the other from a compiler installation

I'm working on a linked list class for my latest project and i would like to be able to access any of it's data members just like an array. Is it possible to override the [] operator so that I can do this? If it's not possible, what would be the next easiest way to access my linked list's data members?
|
|
|
|
|
Yes it is possible to override the [] operator. I haven't got an example in front of me at the moment but it is very roughly:
<br />
CMyElement* CMyArray::operator[]( int iIndex )<br />
{<br />
}<br />

Thanks, I'll work on this :]
I'll post up some code later on when I've got it working.

On a side note: why don't you use some existing class for that ? std::list or std::vector ?
|
|
|
|
|
I didn't know they existed! :P
If I can't work this out then I'll take a look at them.

You should definitively take a look at them (maybe not for this project but at least for the next one). I agree, it looks quite difficult at a first sight but the STL is very usefull. There are some good container classes (list, vector, map, ...) which have been tested by a lot of people. So, you don't need to reinvent the wheel and come out with something that need testing, debugging and is not flexible enough to be reused.

I didn't take a very in-depth look at them but from what I saw I didn't think It would be as easy to do with them what I wanted but I'll take another peek at it tonight and see what I can get out of it.

Hi,
I need to add many buttons to groupbox and it should get the scrollbar if the buttons dont fix in to the groupbox. In .NET we can do it through Panel control. But please tell me how to do it in MFC.

You better make a data model object which is only displayed in the grid.

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 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
Error executing link.exe.

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