Man This Stinks

Could ne one help me here? im now gettin into windows API, and I tried to manually debug it, but I cannot snatch the error. help ne one?

Here it is:

#include <windows.h>

LRESULT CALLBACK WndProc (HWND hWindow, UNIT iMessage, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShowCmd)
{
WNDCLASS kWndClass;

kWndClass.hCursor = LoadCursor (NULL, IDC_ARROW);
kWndClass.hIcon = LoadIcon (NULL, IDI_APPLICATION);
kWndClass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH);

kWndClass.hInstance = hInstance;
kWndClass.lpfnWndProc = WndProc;
kWndClass.lpszClassName = "Alex's Window";

kWndClass.lpszMenuName = NULL;

kWndClass.cbClsExtra = NULL;
kWndClass.cbWndExtra = NULL;
kWndClass.style = NULL;

if (!RegisterClass (&kWndClass))
{
return -1;
}

HWND hWindow;

hWindow = CreateWindow ("Alex's Window", "A Blank Window", WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL);

MSG kMessage;
while (GetMessage (&kMessage, hWindow, 0, 0))
{
TranslateMessage (&kMessage);
DispatchMessage (&kMessage)
}

return 0;
}

LRESULT CALLBACK WndProc (HWND hWindow, UNIT iMessage, WPARAM wParam, LPARAm lParam)
{
switch (iMessage)
{
case WM_CLOSE;
POSTQUITMESSAGE (0);
break;

default:
return DefWindowProc (hWindow, iMessage, wParam, lParam);
}
return 0;
}

I'd Appreciate any help! thanks ohh and here are the errors....

instead of UNIT try UINT where you declare the WndProc procedure...

I could solve every error for you, but that would be of little use to you.

First I recommend you walk through your app and search for missing ; or places where you confused : and ;
I see two errors coming from that.

Then you should correct the error Arawn pointed out. UINT is an abbreviation for unsigned integer.

Next check case. C++ is case sensitive and names of the windows API follow a simple case scheme: types and constants are all capitals (1 error) and functions start with a capital and each word in them also starts with a capital (1 error).

The remaining errors (2) are follow-ups.

Alright, thaks guys, I appreciate it

And please always place your code here between code tags:

[code] Your code here [/code]

It makes it easier to read since the code is posted exactely (formatting) as you wrote it, and it makes it easier to see in a glance what's code and what not.

Ok thanks guys, im down to 1 error, and im guessing its the function begining not begining with a capital, but where?????

Code:

C:\Program Files\Microsoft Visual Studio\MyProjects\Window\Window S.cpp(43) : error C2447: missing function header (old-style formal list?)
Jan 9th, 2003, 05:07 PM
CornedBee

What are the lines around line 43? And 43 itself too of course.
Jan 9th, 2003, 05:08 PM
CornedBee

Could it be that you added a ; here?

Code:

} LRESULT CALLBACK WndProc (HWND hWindow, UNIT iMessage, WPARAM wParam, LPARAm lParam) <-- { switch (iMessage)
Jan 9th, 2003, 05:27 PM
FunyBunyFartAHH

I erased it and still has one error of the header ****ing old style
Jan 9th, 2003, 05:36 PM
CornedBee

Show me your new code.
And mark the line where the error occurs.

alright here:

Code:

#include <windows.h> LRESULT CALLBACK WndProc (HWND hWindow, UINT iMessage, WPARAM wParam, LPARAM lParam); int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShowCmd) { WNDCLASS kWndClass; kWndClass.hCursor = LoadCursor (NULL, IDC_ARROW); kWndClass.hIcon = LoadIcon (NULL, IDI_APPLICATION); kWndClass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH); kWndClass.hInstance = hInstance; kWndClass.lpfnWndProc = WndProc; kWndClass.lpszClassName = "Alex's Window"; kWndClass.lpszMenuName = NULL; kWndClass.cbClsExtra = NULL; kWndClass.cbWndExtra = NULL; kWndClass.style = NULL; if (!RegisterClass (&kWndClass)) { return -1; } HWND hWindow; hWindow = CreateWindow ("Alex's Window", "A Blank Window", WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL); MSG kMessage; while (GetMessage (&kMessage, hWindow, 0, 0)) { TranslateMessage (&kMessage); DispatchMessage (&kMessage); } return 0; } LRESULT CALLBACK WndProc (HWND hWindow, UINT iMessage, WPARAM wParam, LPARAM lParam); { switch (iMessage) { case WM_CLOSE; POSTQUITMESSAGE (0); break; default: return DefWindowProc (hWindow, iMessage, wParam, lParam) } return 0; }

It dose not really tell me where but once I saw a bue arrow right here:

Code:

LRESULT CALLBACK WndProc (HWND hWindow, UINT iMessage, WPARAM wParam, LPARAM lParam); {

The bracket under the function.

So I dont know if this helped you help me....
Thanks ne way.

transcendental

Code:

LRESULT CALLBACK WndProc (HWND hWindow, UINT iMessage, WPARAM wParam, LPARAM lParam); {

Remove the ; like CornedBee has told you.

Code:

LRESULT CALLBACK WndProc (HWND hWindow, UINT iMessage, WPARAM wParam, LPARAM lParam) {

Create a new project that is NOT a Win32 Console Application, but a Win32 Application. Console applications use main as the entry point, Win32 applications use WinMain.
