What is Socket Notification Sink ? s_k13-Aug-02 23:12 s_k 13-Aug-02 23:12  Do you know what Socket Notification Sink is ? Sometimes, when my applications crashes, the message box that shows the fatal error has Socket Notification Sink as the title. When I run Spy++ and look at windows, under my app process is Socket Notification Sink member....??? Thanks. Celebrate Mr. Cesilko! winsock Zizilamoroso13-Aug-02 23:03 Zizilamoroso 13-Aug-02 23:03  I've started a workspace without winsock support, but now, few weeks later, I want to add it. Is it still possible, and how do I do it? [VISUAL STUDIO 6.0] [MFC] [WIN98/2] Bluute tette! Re: winsock Niklas L13-Aug-02 23:10 Niklas L 13-Aug-02 23:10  Project -> Add to project -> Components and Controls and you'll find Windows sockets under C++ components. This is the easiest way in your case. Re: winsock Zizilamoroso13-Aug-02 23:17 Zizilamoroso 13-Aug-02 23:17  tnx [VISUAL STUDIO 6.0] [MFC] [WIN98/2] Bluute tette! Last reliable time at the end of the application s_k13-Aug-02 23:00 s_k 13-Aug-02 23:00  Hi, when is the last reliable possibility to send data to another application at the end of the program ? Destructor of FrameWnd, or destructor of CWinApp ?? Thanks Celebrate Mr. Cesilko! Re: Last reliable time at the end of the application Tomasz Sowinski13-Aug-02 23:13 Tomasz Sowinski 13-Aug-02 23:13  CYourApp d'tor will be called after frame window is destroyed, because application object is global and frame window is created dynamically. Of course, when application destructor is invoked you don't have any documents/views/frames.

Limiting scope of 'using namespace' Niklas L13-Aug-02 22:30 Niklas L 13-Aug-02 22:30  Going through some files from another programmer, I found that he always put a using namespace std; in his public headers. Trying to limit the scope of the using I tried to move the using clause inside the class declaration class C { using namespace std; }; but it results in a compilation error on VC6.0 sp5. But it shouldn't!? Anyone have an idea here? (I finally qualified every single item from the std namspace.)

Re: Limiting scope of 'using namespace' Niklas L13-Aug-02 22:49 Niklas L 13-Aug-02 22:49  I suppose, since you may limit the scope of using to within any other scope, like functions, other namespaces, limited scopes with a { and a corresponding }, it should be possible to us it within a class declaration. That was at least what I thought. Why may I use it within, what seems to be any other scope, but not within a class or struct declaration?

Well, you can't use it because C++ Standard forbids it explicitly: "A using-directive shall not appear in class scope, but may appear in namespace scope or block scope." (C++ Standard, 7.3.4).

Re: Limiting scope of 'using namespace' Niklas L13-Aug-02 23:06 Niklas L 13-Aug-02 23:06  Thank you. I feel better now Do you have any idea why it is has been forbidden? I can't see any clear reason. Does it introduce any problems, and if so what?

CPU Info Venet13-Aug-02 22:28 Venet 13-Aug-02 22:28  Hi All, I'm working on an application that would get system information for each machine on a network and report it back to the central database. I was looking for a function to get the CPU Speed (MHz), however couldn't find one. Are there any functions that would return the CPU speed? (Using Win API to do this.) Thanks. Regards, Venet.

CreateFont & underline pépé13-Aug-02 22:17 pépé 13-Aug-02 22:17  Hello, Is there a way to specify the position of the underline of a font ? thanx Re: CreateFont & underline Tomasz Sowinski13-Aug-02 22:34 Tomasz Sowinski 13-Aug-02 22:34  Set lfUnderline to TRUE in LOGFONT.

Re: CreateFont & underline pépé13-Aug-02 23:33 pépé 13-Aug-02 23:33  I know how to set the underline attribute, but i want to set the position (relative to the baseline) of the line. If possible ! Thanks anyway. Re: CreateFont & underline Tomasz Sowinski13-Aug-02 23:39 Tomasz Sowinski 13-Aug-02 23:39  Sorry - I've misunderstood your question. You don't have any control over position of underline drawn by GDI. You'd have to create non-underline font and draw line yourself at position of your choice.

Image Mazdak13-Aug-02 21:13 Mazdak 13-Aug-02 21:13  My database has a Image field.How can I show each image in my application?

Is it abt retrieving the image from the database or show the bitmap on the screen ? If it is abt the retrieving and assuming that you are using binary you can use the method GetChunk to read the binary data from the database. If abt the bitmap, there are a lot of articles here at CP.
