visual studio 2008 win32 api tutorial HELP

Hi there,

I want to learn how to create win32 api programs.
Does anyone know of any tutorials that i can learn off?

I found a website but it only works with DEV C ++

This is the Code:

Code:

---


#include <windows.h>

int WinMain(HINSTANCE hInstance, HINSTANCE pInstance,
                        LPSTR lpCmdLine, int nShowCmd)
{

       

                MessageBox(NULL, "Hello World",
                "Title", MB_OK | MB_ICONINFORMATION);
               
                if (MessageBox(NULL, "Do you?", "Do You?",
                MB_YESNO | MB_ICONQUESTION) == IDYES)
                MessageBox(NULL, "Yes", "Yes", MB_OK);




        return 0;
}

---

And why do you think that only works with Dev-C++?

I have know idea but feel that you will tell me.

Is it something to with that it doesn't have;

void main()

The absence of void main() is an extremely good thing.

No, the point is: that program works just fine in Visual Studio.

When i debug it i get these errors:

Error 2 error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char [12]' to 'LPCWSTR' c:\users\tecmeister\desktop\c++\win32 api\projects\messagebox\messagebox\main.cpp 10 messageBox

Error 4 error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char [4]' to 'LPCWSTR' c:\users\tecmeister\desktop\c++\win32 api\projects\messagebox\messagebox\main.cpp 14 messageBox

Error 3 error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char [8]' to 'LPCWSTR' c:\users\tecmeister\desktop\c++\win32 api\projects\messagebox\messagebox\main.cpp 13 messageBox

Warning 1 warning C4007: 'WinMain' : must be '__stdcall' c:\users\tecmeister\desktop\c++\win32 api\projects\messagebox\messagebox\main.cpp 5 messageBox

Somehow you've got things set up so that it expects wide-character strings (and obviously I don't). Since I don't know where you set that up, I can't tell you how to fix it -- BUT you should be able to turn all your "string literals" into L"long string literals" by prefixing the quotes with an L. That should work.

Im sorry i dont really understand you properly would you be able to correct it for me so i can see.

Thanks for your help much appreciated.

Well, that's the thing; I did, already. Did you read my post? Did you notice how "things in quotes" became L"things in quotes"? Everything that is "in quotes" needs to have an L in front of it.

Ok now i understand

But that didnt work

Wait -- you're using Visual Studio? Why didn't you click on the Visual Studio download of sample files, instead of the Dev-C++ download of sample files?

I have found out what the problem was it was because i had to change the settings:

Here it is for anyone else who has the same problem:

Change your project configuration to use multibyte strings. Press ALT+F7 to open the properties, and navigate to Configuration Properties > General. Switch Character Set to "Use Multi-Byte Character Set".

Much appropriated tho tabstop
