Adam cabadam@houston.rr.com Conversion Matt Newman13-Jun-01 15:44 Matt Newman 13-Jun-01 15:44  I am learning C++, and I am trying to make globber (Sample on MSDN CD) and it draws a SDI window and all of its functions are LRESULT. I am trying to make it into a Dialog application for easier use but I keep getting errors. Does anyone know how I should go about converting this. Thanks in advance. -Matt Newman Win9X and NT compatibility problem 13-Jun-01 11:05 13-Jun-01 11:05  I'm working on a program that can work with both NT and Win9x. I finish the NT version first, then try it in Win9x. I found that after doing output awhile or moving the window around, the font change!!!! And also the system change too (all system dialog box font changes..).....and if I did something....Win9x asks me to terminate the program too....(this dialog font has been changed too) Moreover, when I do drawing......after the font change.....no colour can be displayed....only black and white. My question is....do i have to do anything when I migrate the NT program to win9x. Are they different? Re: Win9X and NT compatibility problem Michael Dunn13-Jun-01 12:50 Michael Dunn 13-Jun-01 12:50  That sounds like you have a severe leak that's eating up GDI resources. Win9x still has old Win 3.1 memory limitations, so that's why you see the problems on 9x. --Mike-- http://home.inreach.com/mdunn/ #include "buffy_sig" Re: Win9X and NT compatibility problem 13-Jun-01 13:00 13-Jun-01 13:00  Can you tell me what should I do??? Because i really have no idea how to fix the problem. But thanks to telling me that. Re: Win9X and NT compatibility problem Anders Molin14-Jun-01 2:55 Anders Molin 14-Jun-01 2:55  You say you do drawing. Maybe you allocate some stuff, like CreateDC() and then forget to call DeleteDC(), this could also be with brushes, pens, bitmaps and... If you do that kind of custom drawing, without releasing the resources you use, Win9x can run out of GDI resources pretty quick. - Anders Money talks, but all mine ever says is "Goodbye!" on screen drawing in other fullscreen applications? 13-Jun-01 9:37 13-Jun-01 9:37  Hiya! Is there a way to draw or write something on screen when another program, a game using opengl or directX for example, is running? If so, how?

Document Opening Jim Hewitt13-Jun-01 9:11 Jim Hewitt 13-Jun-01 9:11  I have an SDI app which stores and retrieves its contents using serialization. the app will only ever use one data document, so i want to hard code the open and save commands to save the user from using the menus and toolbar buttons. I've tried using the OnOpenDocument command with limited success......my problem is essentialy that I don't know where to place the command so that it effectively prevents the automatic doc opening in the template construction. A fairly basic question I know, but if someone could take the time to help it would be appreciated. Re: Document Opening Chris Meech13-Jun-01 9:21 Chris Meech 13-Jun-01 9:21  Try using OnOpenDocument("YourFilename.ext") in InitInstance. I'm not sure what to use in ExitInstance for the save though.

Just to make it clear I'd like something similar to the Query Design in MSAccess, so you can resize and move the control around its parent window. []'s Crercio O.

Re: COleDateTime to CString Michael Dunn13-Jun-01 8:29 Michael Dunn 13-Jun-01 8:29  You don't cast it.

CDC::SelectObject(/* Some font */) doesn't work in NT 13-Jun-01 5:13 13-Jun-01 5:13  Can someone tell me, why in Win98 CDC::SelectObject(/* Some font */) selects the proper font, e.g. Times New Roman, while in NT no selection is made Re: CDC::SelectObject(/* Some font */) doesn't work in NT Tomasz Sowinski13-Jun-01 5:37 Tomasz Sowinski 13-Jun-01 5:37  More code, please.

Use other charset ID appropriate for your locale. Tomasz Sowinski -- http://www.shooltz.com.pl
