When I try to compile your code (I use Dev-C++) I get the following error:

[Linker error] undefined reference to `TextOutA@20'

There's no indication of a line or file so I have no idea what I'm doing wrong or what is wrong in your code. :unsure:

You have to link with gdi(libgdi32.a) library
And it's a Win32 Gui project. I don't have to add libgdi32.a manually, maybe you compiled it as console project? If not then add the libgdi32 library to the linker options.

Hey, Xception, that's pretty cool. The only thing I can do right now in C++ is using different controls (buttons, etc.). The clock doesn't seem that hard either. I have a question, though. When I use LRESULT CALLBACK ..., I use WndProc instead of WindowProcedure. There is no difference there, is there? If you could, please see my topic in C++ Help. I need some help from somebody who's quite a bit more experienced than the rest of us here. :)

That is pretty cool Xception. But what should we expect from someone of your caliber. :)

Dragon, you can call the window callback procedure what you want, in the window structure you tell windows the name of the callback procedure:

CODE

wincl.lpfnWndProc = WindowProcedure;   // This function is called by windows

Sweet! You ARE a good programmer Xception. Is there any chance you can make it say AM and PM other than using 24 hour time? because at the time i tried it out it said: 15:56:03

That would be a good update for it.

When I compile the script, the box around the time is in white, now my W98 settings are set so that windows and box are grey. Is there a way to alter the colour of the box to Windows settings?

Is it really that hard to read 24-hr. time? It shouldn't be that hard, though, to convert it to AM/PM time.

I'm not bad at reading 24-hour time...i'm just not used to it. it was 3:56 PM when i used it.

And 3 seconds. B)

And I'm not good in reading those AM/PM times... I live in Finland and here we use ONLY 24 hour system... ;)

I did. Now it works. Looks nice.

I'll see if I can make any sence out of that code :) .

Nice looking clock you got there, you should theme it, lol

HOLY THREAD RESURECTION!

for a minute there i thought dr voodoo had a little brain fart, then i realized it was a post from when he was a beginner. just goes to show everyone starts in a simmilar way :)

i don't understand people who ressurect topics and doesnt add anything to it except "good job" ;)
