Error when following tutorial

Hi, my name's Daggio and I'm new here
nice to meet you :D

I just follow a tutorial at http://www.cprogramming.com/tutorial...ogramming.html

and encountered an error like this:

1>c:\documents and settings\yadhiek\my documents\visual studio 2008\projects\cpopengl\cpopengl\belajar.cpp(5) : error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char [14]' to 'LPCWSTR'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>Build log was saved at "file://c:\Documents and Settings\Yadhiek\My Documents\Visual Studio 2008\Projects\CPOpenGL\CPOpenGL\Debug\BuildLog.htm "
1>CPOpenGL - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

and this is my code

Code:

---

#include <windows.h>

int APIENTRY WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
        MessageBox(NULL,"\tHello World!","My first windows app",NULL);
        return 0;
}

---

line 5 is the

Code:

---

MessageBox(NULL,"\tHello World!","My first windows app",NULL);

---

I don't know what went wrong, I've followed everything in the tutorial.

thanks before :D

Go into project options -> general -> character set -> change from unicode to multi-byte and it should work.

It worked! thanks Elysia :D

er....I'm allowed to write one line post if it's a thank you right?
but then again, this is no longer a one line post ^^;

Sure, if you write something useful or thank someone.

er... I encountered an error again, this time when following the next tutorial (it's at http://www.cprogramming.com/tutorial...ndows_app.html )

actually, everything worked fine... except for the window disappeared in a blink of an eye

I've read the FAQ and it suggest me three things. The first was to open in via command prompt, I've tried this and still the same... gone in a blink of an eye... literally ^^;

then I tried the next way, to stop it as if it's waiting for user input... I included the

Code:

---

#include <stdlib>

---

and right before

Code:

---

return msg.wParam;

---

I wrote

Code:

---

system("PAUSE");

---

so the last lines of my code looked like this

Code:

---

system("PAUSE");
return msg.wParam;

---

but the result is pretty much the same.. I can see the window now it's just there's also a console window with a string of "Press any key to continue..." appearing

and oh yeah... the window is not responding, I've checked this using windows task manager

any help would be appreciated :D
thanks before guys

You need to make sure the message loop is running.
As long as the window is visible and recieves messages, the message pump will continue to block.
The message pump is this:

Code:

---

        while(!done)
        {
                PeekMessage(&msg,hwnd,NULL,NULL,PM_REMOVE);
                if (msg.message == WM_QUIT) //check for a quit message
                {
                        done = true; //if found, quit app
                }
                else
                {
                        /*        Translate and dispatch to event queue*/
                        TranslateMessage(&msg);
                        DispatchMessage(&msg);
                }
        }

---

The FAQ solutions are for CLI-type apps only and won't work for GUI-apps.

it worked! thanks Elysia :D

the error turned to be a typo, I typed '=' instead of '=='

my bad ^^;

You know that if you turn up warnings to max, the compiler will warn if you use = instead of == in ifs.
