wierd optimization action....

Recommended Posts

Hey Im having a bit of trouble with visual studio 6. Ive got a basic window shell im compiling...compiles fine in a debug compile, but with the release compile with the speed optimizations on, and you open the exe not from visual studio but from windows it just closes as soon as it opens. Its wierd. Id really like to see if I messed up with my code or is it the compiler. Im pretty confused. Heres the zip with the source and binaries....thanks http://www.ngforce.com/win3201.zip

I have downloaded your source code, and ran your Release.exe. There was no problem there. I also ran it through MSVC++ in release mode, and again, no problems.

Does it work properly in debug mode on your machine??. If not, make a break point and debug it step-by-step. Then when the error occurs, you can tell what function, or pointer, etc is causing the problem.

Im sorry I cant be of more help, but I dont seem to be having this problem

Er.

I haven''t had a look at your code, but console apps usually close when they''re done executing in Windows. MSVC adds a "Hit any key to continue" at the end of program execution to allow you to see what happens.

If that''s the case, add a getch(); at the end of your program.

Duh! ''Console apps'' are intended to be run from a pre-existing console.

Bad idea. You''re better off creating a .pif file for your app.

Care to elaborate?

This was a windows program. When I comiled with the speed optimizations on the program crashed as soon as it launched, but on the debug compiled exe it ran fine. This stopped happening when I installed service pack 6 for visual studio 6....I also had some wierd action with my resource scripts not compiling before I updated...anyone else have simular issues with XP and visual studio? Again everything seemed to be fixed after I updated it...

Differences between debug and release mode are usually caused due to (not) initialized variables.

In debug-mode, all variables are usually initialized automatically, but on release mode they just stay unchanged.

check your code for such cases, helps most of the time.

PIF files are files that are/were used to control properties of DOS programs when run in Windows - though you can use them to some extent with windows console apps. These properties include, among other things ''Close window on exit''. Even if you don''t use that, it is trivial to create an auxiliary program (e.g. a batch file) that will call your console app and add a pause at the end:

MyProg.bat
MyProg.exe
PAUSE


If you add a getch() or system("pause") or whatever at the end of your program, you will get that ''interruption'' of the program flow even if you use it within a standalone console (start command.com/cmd.exe then call your program from there) or if you use it within a shell script.

Keeping that interactive ''junk IO'' outside of your main program is a Good Thing in my book.
