_WIN32_WINNT & _WIN32_WINDOWS Nemanja Trifunovic1-Aug-01 9:47 Nemanja Trifunovic 1-Aug-01 9:47  I saw that some (new) function definitions in Winuser.h are "guarded" by: #if (_WIN32_WINNT >= 0x0400) || (_WIN32_WINDOWS > 0x0400) ... #endif I've also noticed that afx.h sets _WIN32_WINDOWS to 0x0500. Can anybody tell me more about these macros ? I vote pro drink Re: _WIN32_WINNT & _WIN32_WINDOWS Not Active1-Aug-01 10:08 Not Active 1-Aug-01 10:08  _WIN32_WINDOWS tells what version of OS you are running. 0x0500 means Windows 2000. If you want to target systems such as NT4 you would set _WIN32_WINNT = 0x0400. You may also need to set _WIN32_IE appropriately for some IE features, like Active Desktop. Some features are not available on lower systems so they are placed in the "guarded" section to prevent their use. Printing a window v_krishnan1-Aug-01 4:33 v_krishnan 1-Aug-01 4:33  Hi, Is there any way to print a window and its contents onto the printer just like it looks on the screen without capturing its bitmap?

Re: but... Christian Graus1-Aug-01 13:17 Christian Graus 1-Aug-01 13:17  Yes, but OnOK is still called when you press it. If you deleted the Cancel button, Escape will still call OnCancel. To defeat this behaviour, override the methods before deleting the buttons and comment out the calls to the base class. If you wanted the OK button to work but not the return key you can do this: GetAsyncKeyState(VK_RETURN); // Clear buffer if (GetAsyncKeyState(VK_RETURN)) return; // Don't execute if we got here via the return key For this project, put a new IDOK button on, then override the method, and delete it again.

Thanks! Derek Resizing a FormView to the size of the dialog displayed skfnmuislædmufaæoi1-Aug-01 1:25 skfnmuislædmufaæoi 1-Aug-01 1:25  Does anybody know a way to resize a CFormView derieved class, so that it exactly encloses the dialog resource and no scrollbar are visible? I tried it on CWnd::SetWindowPos(), but this does only change the size of the View and didn't affect the frame. -------------------------------------------------- "Pseudocode is code to demonstrate a concept, not designed to be run.

" Re: Resizing a FormView to the size of the dialog displayed Tomasz Sowinski1-Aug-01 2:38 Tomasz Sowinski 1-Aug-01 2:38  I think you should control the size of parent frame to avoid scrollbars. Use WM_GETMINMAXINFO for that.

(i need them both work simultaneous) can i write something like this: ... AfxBeginThread(Function, ...) AfxBeginThread(Function, ...) ... thanks Re: Thread Bob Groves1-Aug-01 2:00 Bob Groves 1-Aug-01 2:00  Yes. You will get two threads running, each with "Function" as its main. Re: Thread 22-Jan-02 23:41 22-Jan-02 23:41  Maybe works, maybe not. I would advise you to move Function() into a class (CWinThread derived) and make instances of the class for every thread. There is a second overload for AfxBeginThread, not taking a function pointer as first param, but a CWinThread-object. Look at http://www.codeproject.com/threads/extended_thread.asp it demonstrates a similar approch mfg HintiFlo Microsoft Visual Studio 1-Aug-01 1:00 1-Aug-01 1:00  Does anybody here have faced any problem using Microsoft Visual C++ 6.0 in Windows 2000.
