Centralise Database kubbazoob8-Dec-02 5:41 kubbazoob 8-Dec-02 5:41  Hi There, I have a problem. Everytime my recordset is opened, it makes a connection to my database (Access database). Is there a posibility to make a global pointer to the database? And where should i put it? Thanks Re: Centralise Database Michael P Butler8-Dec-02 9:37 Michael P Butler 8-Dec-02 9:37  I tend to place my single database connection object into my CWinApp derived class. I then access it using AfxGetApp. Michael Fat bottomed girls You make the rockin' world go round -- Queen findexecutable() pnpfriend8-Dec-02 5:03 pnpfriend 8-Dec-02 5:03  why am I getting runtime error at function < FindExecutable(fname,path,result) > called???

I would suggest in your declaration should set LPTSTR result = NULL; then you would easily see what is going on Re: findexecutable() Michael Dunn8-Dec-02 7:27 Michael Dunn 8-Dec-02 7:27  From MSDN: lpResult: Address of a buffer to receive the file name when the function returns. You're passing result which is just an uninitialized pointer, it's not a buffer nor is it pointing at a buffer. --Mike-- Friday's GoogleFight results: Britney Spears 2,190,000 - Erica Weichers 23 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!

Martin Haesemeyer8-Dec-02 1:15 Martin Haesemeyer 8-Dec-02 1:15  Hi folks! I have a really stupid problem (maybe it is totally easy to solve an I just don't get it): I created a dlg based application with MFC, with some controls in it. One is an edit-control. And now I want that the user can enter text *with tab stops* in the edit control. But naturally the dialog manager interprets all presses of the tab key as the desire to switch focus... Now I'm totally stuck. I ovverode PreTranslateMessage, trapped WM_KEYDOWN, checked wether the editcontrol has focus, checked for VK_TAB and if these conditions were met, I send a WM_CHAR to the edit control instead of calling the base-class (pseudocode): PreTranslateMessage(message){ if(message == WM_KEYDOWN) if(message.wParam == VK_TAB) if(myEdit.HasFocus) myEdit.SendMessage(WM_CHAR,'\t'); else CDialog::PreTranslateMessage(message); } But the whole effect was generating some strange behaviour...(I also tried sending a WM_KEYDOWN,WM_CHAR,WM_KEYUP but same effect) Is there some other solution to this problem??

File properties via C++ Bats8-Dec-02 0:45 Bats 8-Dec-02 0:45  In terms of the extended properties for files (in windows 2000) is there some way to extract them via C++. The method should be: 1. Able to access the "Category" and "Comments" properties at least. 2. Not restricted to MS-only file types (like .doc etc) Any word would be grand !

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 Re: FTP without Wininet User 66588-Dec-02 1:45 User 6658 8-Dec-02 1:45  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. regards modified 12-Sep-18 21:01pm. Re: FTP without Wininet carrie8-Dec-02 6:10 carrie 8-Dec-02 6:10  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.

I looked up the RFC too but 69 pages is too much. Thanks Simple question about Socket ! Hadi Rezaee7-Dec-02 23:41 Hadi Rezaee 7-Dec-02 23:41  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 ! My month article: Game programming by DirectX by Lan Mader. Please visit in: www.geocities.com/hadi_rezaie/index.html Hadi Rezaie Re: Simple question about Socket ! User 66588-Dec-02 2:14 User 6658 8-Dec-02 2:14  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 regards modified 12-Sep-18 21:01pm. Cursor doesn't change S O S7-Dec-02 23:11 S O S 7-Dec-02 23:11  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? Re: Cursor doesn't change KaЯl8-Dec-02 21:43 KaЯl 8-Dec-02 21:43  Try to implement an answer for message WM_SETCURSOR in your child frame (have a look to CWnd::OnSetCursor in MSDN).
