Hi All,
I am working on implementing a callback function in this manner :

void CALLBACK InternetStatusCallback(HINTERNET hInternet,
DWORD_PTR dwContext,DWORD dwInternetStatus,
LPVOID lpvStatusInformation, DWORD dwStatusInformationLength)

and then I make a call as

hInetOpen = InternetOpen("MY_FTP",INTERNET_OPEN_TYPE_DIRECT,NULL,NULL,
INTERNET_FLAG_ASYNC);
INTERNET_STATUS_CALLBACK inetStatusCallback  =InternetSetStatusCallback(hInetOpen 
,(INTERNET_STATUS_CALLBACK)InternetStatusCallback );
if(inetStatusCallback  == INTERNET_INVALID_STATUS_CALLBACK)
	{
		CString szErrMsg;
		szErrMsg.Format("%s: %d", "InternetData :  InternetSetStatusCallback: ",GetLastError());
		return false;
	}

The problem is that the callback function is never called.

Somethings seem HARD to do, until we know how to do them.

Hi,

I would like to freeze one column of my listview which is in report style, just like the way it can be done in excel.

If the listview has a lot of columns, to navigate to the last column we use the scroll bar. While scrolling I would like the 1st column to remain where it is and not disappear while scrolling.

Please can you give me an idea how to do this?

Thanks,
Tara

Unfortunatly you cannot do that with ListVie, you need Flex Grid or other grid control for that!

C++ is a language; VC++ is short for "Microsoft Visual C++" which is Microsoft's C++ compiler (and linker and IDE...)

MFC is a framework, written in C++, for making applications for Windows in C++ and comes with (MS)VC++.

VC++ is the environnement. Visual C++ IDE allow you to program in C/C++, or C++/CLI.

MFC is only a C++ framework that wraps the Win32 methods and allow you to handle them more easily...

VC++ = Visual C++ = Microsoft Visual C++ = IDE for developing C/C++/CLI components and applications

MFC is a C++ library (set of classes) that wraps the Win32 API (which is in written in standard C).

retain items in the list control

You know C right? You make a lot of thing in the console. But if you want to create a windows button ? a textbox ?and the things that targets MS Windows. So we need a visual API right? It's called Win32API. 32 is to say the API is for 32 bit Windows OS. It's fully "C" based.

Now C++, why do you need C++ when you have C?
C is all function oriented. When your program get into 1000s of lines . It becomes a hell. C++ has a lot of features that complies to OOD(Object Oriented design). It makes things much easier to control when projects expand out of boundary. So why not Use C++ instead of using "C" for visual programing with the Win32 API. Here comes MFC Cool | :cool:

, It wraps all your raw win 32 Apis and gives everyting as classes. You create an Object to that class, and play with it easily. MFC is the Object Oriented framework in C++.

Win32,MFC,ATL,WTL etc comes under VC++. VC is the compiler provided by Microsoft for creating these programs. So never say MFC or VC++, may be you can say.. Win32 or MFC.

how do i retain items in the list control so that even when i close the application, the items would still be availiable in the list control.

Save it to a file. At the time of retrieval just read from the file

Read the items from the list control. When you are closing your application/relevant dialog write the contents of the list to a file.
Use CFile, CStdioFile, fread() / fwrite() to put/get the data to/from the file and put it in the corresponding rows/columns of the list control when you are calling the list control dialog to display again

So have you not studied up on file I/O? That's very basic stuff, that should be mastered before advancing on to more difficult topics.
