Thank you Kaud!
I managed to read other REG_DWORD values by modifying the code with the help of your link but this specific key returns me 0.
Edit: but on another machine its working so it must...

I can read REG_SZ values but not REG_DWORD values from the registry.
Do I need another type than char* as 5th parameter of the RegQueryValueEx() function if I want to read REG_DWORD value...

OK, I found out how to debug threads. :)

OK, the crash is occurring in the "void Get_Column_Info()" function that I call by the thread "std::thread Column_Info_Thread(Get_Column_Info);".
But when I try to step into this thread by F11 to...

Thank you Victor, the Call stack window shows:

Im trying to debug a Win32 visual program because I have a "invalid pointer crash" but I cannot find it where because stepping over with F10 at a certain point debugging just stops and I cant...

So if I understand it well, the compiler knows that they are there and only going to allocate them once.

Ah, OK I get it now!
I had to calculate the 25 from the 100, so its 100+25.
Thank you Victor, I thought I would have never understood it. :)

Thank you, very informative!
That makes sense, thanks!

My 'top left' of the rectangle that I'm invalidating is actually the bottom left?
Then how come it writes to the right place when you move a window over it?

So its best to declare them in the "case" that uses them.
I think globals are bad in a large program where you use them in different places. In a small program it doesnt really matter.

I think the coords are OK because if I do this it will write to the same place.
TextOut(hdc, 20, 100, buf, strlen(buf));
TextOut(hdc, rText.left, rText.top, "ccccccccccc", 10);

Thanks a lot for the explanation!
So it's OK if I stop declaring them there and just declare them as globals instead?

I see variables declared even in professional code outside of the switch() message loop inside WndProc.
It means that they are declared at least 100 times a second again and again.
How is it a...

Im trying to refresh one part of the window with InvalidateRect but it wont get refreshed right away. It will be if you move another window over it.
What am I doing wrong?

On MSDN it says /LIBPATH:dir is the switch to add additional lib path.
In the cl.exe --help there is no such a switch.
And when I use /LIBPATH:C: I get D9002 'Ignoring unknown option' error.

I'm following this MSDN tutorial to preview video from my webcam.
I wrote the code but it's crashing on

Yes, TreeView_HitTest is the way to go. There is even a pointer to the item clicked: lpht.hItem.
Thank you very much for both of you! :)
Happy New Year!

I would like to use this solution as it seems to be the simplest but the problem is that you wont get TVN_SELCHANGED message if you click the same item again since the item is still selected.
January 2nd, 2015, 02:20 PM
Yes, I thought about that solution but the problem is that NM_CLICK detects any click anywhere in the treeview not only on the items.
How to know if the user clicked on the same item and not just...
