    Re: Controls in MFC

    I suspect that it probably has to do with another stack variable either before or after "INITCOMMONCONTROLSEX InitCtrls;" which is over/under-flowing. All the ICC_xxx defines are the same size...

    No, the buzzword is "Desktop Composition". It is sort of a cache of window contents maintained by the OS to keep a better idea of what windows are doing and to improve performance. You should still...

    Re: Winsock connect to IP

    Something like this?:



    SOCKET sock;
    unsigned long ip_addr;
    struct sockaddr_in client;

    ip_addr=inet_addr("192.168.1.10");
    memcpy(&client.sin_addr,&ip_addr,sizeof(ip_addr));

    Actually, I believe it is your first line. CreateCompatibleDC(NULL) will produce a monochrome DC until some object is selected into it. Instead, try CreateCompatibleDC(GetDC(hWnd)) where hWnd is a...

    Re: VBC++ help with putting stuff into a file

    I do this habitually too. For me, it goes back to the days of writing programs on punch cards. I'm an old dog and I don't like to learn new tricks.

    Re: Need tweaking done for a SMTP Client.

    I didn't say anything about teaching. It seemed implicit in your post that you were doing this as an exercise in learning network programming.

    I just took a quick look at RFC3207 and it seems...

    Re: help :IP,subnets,broadcast etc

    The netmask is part of the IP configuration for the interface. You can't just guess. With that broadcast address, this looks like a class A network. How come you don't have the netmask information?

    Re: Need tweaking done for a SMTP Client.

    I don't know much about TLS, but doesn't that hand off the process to another port? Are you using port 25 or port 587?

    At any rate, encrypted email seems like a bit much for a learning example.

    Re: Messing with libraries bitness on link

    IA64 binaries are NOT compatible with x64 binaries in the windows world. I'm not sure what you are trying to do, but you seem to be mixing two types of binaries in your linking step.

    Re: Self-referencing header files

    Don't include the header, just use a forward declaration of the class.

    Re: Telnet Help

    That's probably the telnet server querying the client for supported options. These are established before the session ever gets to a prompt. See the telnet RFC:

    Re: How can convert a char array to CString?

    Just use CString's = operator. It will handle the conversion:



    CStringW csw; //force wide cstring regardless of UNICODE setting
    CStringA csa; //force multibyte cstring regardless of UNICODE...

    Re: Create compatible bitmap

    In this case, since you mentioned it's an 8-bit BMP, it appears that you are corrupting your bitmap by loading the pixel information into the color table area. An 8-bit BMP has a table of 256 DWORDS...

    what is the "case WM_PAINT:" doing in your button handler? It should be a separate case on the same level as WM_COMMAND. What you need to do is ONLY paint in the WM_PAINT handler (the correct one)....

    How much clearer can I state it? There is a palette in the file and a palette in the bitmap structure. Commenting those lines makes the code fail to load the palette from the file. Without filling...
