Hi,
I'd like to do some FTP stuff without the use of WinINet. I'd like to do all the stuff myself. Could somebody guide me to some site that has more info concerning this? Thank you very much

Well, I recommend you to study the FTP RFC (dunno what number it is) and send all commands using TCP/IP. There are a lot samples here at codeproject.

Bare-ass Winsock or Berkeleys sockets is the way to go. I recently made a simple FTP client application after spending ages try to get Wininet to connect to 2 servers simultaneously, only to find out that it didn't support it. I was trying to get Server->Server transfers working so it was a bit of a pain for me, but using Winsocks it wasn't too much of a struggle.

Thanks, that's kind of what I was looking for. I looked up the RFC too but 69 pages is too much. Thanks

Simple question about Socket !

Hello,

Imagine a Client/Server chat program.
How the Server listen to clients for their requests for connecting them to it ?

I know there is Listen() function in MFC socket classes.
But where should i use it ?

Is there any special message in MFC socket classes for listening ?

Thanks in Advance !

Well, if you use MFC you simply need to call Listen() once after you have set up your socket with Create() and Bind().
Once your app is in listen mode you'll get notified about incoming client connections through the OnAccept() notification of your CSocket-derived class

Cursor doesn't change

The cursor doesn't change voer any of my windows in a MFC MDI app.
(MDI Child windows, other windows ive created)
I mean, if I put mouse over border to resize it, and then quickly move mouse over the window, the resize cursor stays.
I just wait it to change to the arrow cursor...
MSDN says that the default implementation of the cursor change message is to change to the arrow... why is it not working?

Try to implement an answer for message WM_SETCURSOR in your child frame (have a look to CWnd::OnSetCursor in MSDN).

AfxGetMainWnd()->Invalidate() is one way.

I tried, but that didn't seem to update any windows? Hmm maybe I did it a bit wrong.. I'll see...
Nope, doesn't effect the child windows...

How to judge a handle?

Hi,

I have a windows handle which is returned by third party lib, this handle sometimes is valid, sometimes isn't. I want to know whether there is method or function to judge the validity of a handle?

Thanks,
Jeff Xi

There are ways, but it depends on the type of handle that you are dealing with.

Do you have a window handle, a GDI handle, a file handle, or something else?

If it's a handle to a window, you can call IsWindow().

For other handles and Win98 compatibility, you could use DuplicateHandle() and check the error returns (don't forget to close the duplicated handle if successful.)

Detect the path where is running an application VC++

I'd like to detect the folder (path) where a my application is running
and put the data in a string. - Can somebody give me some suggestion
(without using the system() funcion)? - Thanks - giovanni.

If you mean the path where your .exe is located, you can use a function:
GetModuleFileName(...), where you put your exe module instance handle and retrieve the whole path including the exe module ("c:\windows\notepad.exe"). Then you have to simply strip the exe name and voila you have path.

If you mean the current directory for process, use GetCurrentDirectory()

Re: Detect the path where is running an application VC++

Roman Fadeyev7-Dec-02 23:59

geo_m is completely right. But I would add little remark: you can pass NULL to GetModuleFileName() to retrieve your app path. It's easier to use. Especially it is important to pass NULL when you get AppPath from DLL.

How to cut filedir from path? All functions for manipulating with filenames are placed in shlwapi.h. Their names are beginning from "Path" word. For example: PathFindFileName (Searches a path for a file name). Also you can use C++ function _splitpath

An example:

char szDrive[_MAX_DRIVE];
char szDir[_MAX_DIR];
char szFileName[_MAX_FNAME];
char szExt[_MAX_EXT];
char szBuffer[_MAX_PATH];

// get path of executable
GetModuleFileName(NULL, szBuffer, _MAX_PATH);

// split into parts, to get the Path
const char* pFilePath = szBuffer;
_splitpath(pFilePath, szDrive, szDir, szFileName, szExt);

CString strPath;
strPath.Format("%s%s", szDrive, szDir);
TRACE("File Path is %s\n", strPath);
