I have solved the problem... removing the bind() function execution. Acording with the MSDN documentation: "The bind function is used on an unconnected socket before subsequent calls to the connect or listen functions. It is used to bind to either connection-oriented (stream) or connectionless (datagram) sockets. When a socket is created with a call to the socket function, it exists in a namespace (address family), but it has no name assigned to it. Use the bind function to establish the local association of the socket by assigning a local name to an unnamed socket." I understood that the bind function is not necessary, because I only want to send datagrams with a SOCKET to server and receive the responses by the same SOCKET, and the WSAAsyncSelect function grants the data response to the app. This is correct? Thanks, Cris.

No, the UAC configuration is not enabled.

This is my code: SOCKET m_maSocketOut; struct sockaddr_in m_SockAddrOut; unsigned long m_lInet; . . void init(CString strServer) { unsigned long lInet=0; memset(&m_SockAddrOut, 0, sizeof(m_SockAddrOut)); m_maSocketOut = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDP); m_SockAddrOut.sin_family = AF_INET; m_SockAddrOut.sin_port = htons(port); struct hostent FAR* hp = gethostbyname((char FAR *) (const char *) strServer); if (hp == NULL) { lInet = inet_addr((const char * ) strServer); if (lInet != INADDR_NONE) { validIP = TRUE; byAddress = TRUE; } } else validIP = TRUE; if (validIP) { if (byAddress) { m_SockAddrOut.sin_addr.s_addr = lInet; m_lInet = lInet; } else { m_SockAddrOut.sin_addr.s_addr = *((unsigned long far *) hp->h_addr); m_lInet = *((unsigned long far *) hp->h_addr); } if (m_maSocketOut != NULL) { bind(m_maSocketOut, (SOCKADDR*)& m_SockAddrOut, sizeof(m_SockAddrOut)); WSAAsyncSelect(m_maSocketOut, hWnd, WM_EXTERNA, FD_READ | FD_CLOSE); } } } void sendData(char szData[], int len) { int result = sendto(m_maSocketOut, (char FAR *) &szData, len, NULL, (PSOCKADDR) &m_SockAddrOut, sizeof(m_SockAddrOut)); m_SockAddrOut.sin_addr.s_addr = INADDR_ANY; if (result < 0) { int erroCode = WSAGetLastError(); //erroCode = 10022 in Windows Vista!! } } Important: This error code is only on Windows Vista, but not all instalations . I don't know which the exat situation, but I observed in Business and Ultimate version. Any idea?

Hello, I have UDP app that works fine, except on Windows Vista. The error is WSAEINVAL (10022) on sendto function, and the package did not send :-( Anyone know this problem? Thanks, Cris.

Thats right... I have fixed my problem reseting the UAC configuration. But, why the UAC configuration cause this problem? []'s Cris.

Hello, I have a problem reading data from a INI file using GetPrivateProfileString method, only on Windows Vista. When I read from a CFG file no problem, but GetPrivateProfileString always return the default value reading a INI file located on Windows directory (C:\Windows). Anybody knows this problem? Thanks, Cris.

People, any idea?

Hello, I have setting a background image into a ListCtrl with SetBkImage() method. But the image is showed with a scroll, like the texts in the rows. How could I disable the scroll of the background image? I hope to put the image fixed in the background of ListCtrl. Any idea? Thanks, Cris.

Hello, I have to find how change the menu background color (menubar and menuitems), but nothing yet. On true, I want to change my dialog based app background color (I am using SetDialogBkColor() method), but the menu (I have a menu in the dialog too) continue with the default system background color. So, I only want to change the menu background color (same color of my dialog background). Could anybody help me? Thanks, Cris.

Hello, Anybody have an idea? I have find in the net, but nothing found. Please take a look in this problem ;-) Thanks again, Cris.

Hello, How could I change only the menu background color? I have subscribed the DrawItem method of CMyMenu class (derived from CMenu). Could any show me the code to do this? Thanks, Cris.

Hello, Anybody knows some skin tool to became my APP skinable? I found SkinCrafter and AppFace? Anybody knows these? Thanks, Cris.

OK, thank you again.

The problem is also build a rotine for each file format.

It's not possible. An app cannot print a document from disc directly to printer. I should do this with the app that can read the document. :-( Thanks for your atention. []'s

But this file can be a .DOC file, with image included and formatted texts (bold, italic,...), then I need to build a app that the user select any file and OK. The app should send the file to a postscript printer for convert to .PS format. Can I do this, only with my app?

But my file can be any format, not only text file. I need to print a image too. Any other idea? []'s

That's right. I need to do this programatically.

Thanks for your help. I have a printer device and a file name on hard disc. How can start a print job passing these parameters (printer and file name)? []'s
