Win32 Application Tutorials Not Working....

This is stemmed from this topic i made @ http://vbforums.com/showthread.php?t=430985


For Some Reason Ever Since i re-formatted my computer and re-installed everthing i needed to. Such as The Platform SDK(R2), DirectX 9 August 2006 SDK.
I havent been able to compile projects that i used to be able to compile.

For Example. This is just a simple app that prompts a mesage box upon loading.

This is the code:

VB Code:

#include <windows.h> 
 
int WINAPI WinMain( HINSTANCE hInstance,HINSTANCE hPrevInstance ,LPSTR lpCmdLine ,int nCmdShow){ 
 
    MessageBox( NULL , "Hello World!", "Win32 Tutorial" , MB_OK ); 
 
    return 0; 
}

This used to run in VC++ 2005 Express Edition(Tho idk if it was still a Beta..LOL)

Anyways....Is it just me... or do i need to get Visual Studio 2005 to fix this problem...

However... This same example works with Dev-C++. But since i want to work with DirectX, im going to stick with VC++ 2005 Ex Ed... soon to be VS 2005.

:For Those that hate double posters:
You might think im double posting... but im not.This is a totally new question surrounding an old question

So what is the error?

hehe...ooops.
forgot error...

This is using VC++ 2005 Express Edition..

So would this be fixed by installing Visual Studio 2005?

That MessageBox() call is expecting a Unicode string literal and it's getting a Single Byte Character Set literal. Putting an L in front of each string literal might resolve the problem:

MessageBox( NULL , L"Hello World!", L"Win32 Tutorial" , MB_OK );

hmm...k i'll try after work tomorrow.

Better to wrap them in TEXT(), so that it works for both ANSI and UNICODE compiles.
MessageBox( NULL , TEXT("Hello World!"), TEXT("Win32 Tutorial") , MB_OK );

*No Bump*

was there some sort of an update since august 2005?
Which is the last time i has re-installed "everything". Because i've been able to compile the tutorials from functionx.com/win32/ and gameprogrammer.org (win32 tutorials) since then.until last month...

I just find it wierd.... cuz now ima have a harder time in learning C++/Win32/DirectX

Is it always the same error or different errors?

With Every tutorial its the same error.. but i guess i cant use those tuts anymore ... and i cant find any "newer" win32 Tutorials... so its hard for me to learn.


BTW... I now have VS 2005 Standard Edition installed.(Just thought i let you know i dont use Express Edition, anymore..)



What i guess im really trying to ask now is... Know any sites/books that offer Win32 Tutorials/Examples that were published since .... Jan 2006? lol..

I tried looking thru MSDN for Win32 Examples/Tutorials... but i couldnt find any.

What error?

Old tutorials should work. Aside from the instructions on how to set up a project, it's absurd that they wouldn't. After all, old programs need to work, too.

the code in my first post used to work in VC++ 2005[Before Re-Formatting of HardDrive] and Dev-C++. But now it only works in Dev-C++. But when i do VC++ 2005 .... it errors unless i change the strings to "L"iteral strings...

So maybe just maybe... i had an option on in VC++ 2005 that made strings literal... or... im just losing my mind... since i REALLY WANT TO LEARN C++/Win32.. So that i can go onto DirectX..

also, im sorry if i keep ranting about the same thing... Its just... i want to learn... but i keep having road blocks, the size of grand canyon, in my way.

2005 has Unicode compilation enabled by default. Wrap every string literal in the TEXT() macro and it should work.
