I would suppose in Win32 code you would do the following Wink | ;)

void CWnd::ScreenToClient(LPRECT lpRect) const<br />
{<br />
	ASSERT(::IsWindow(m_hWnd));<br />
	::ScreenToClient(m_hWnd, (LPPOINT)lpRect);<br />
	::ScreenToClient(m_hWnd, ((LPPOINT)lpRect)+1);<br />
	if (GetExStyle() & WS_EX_LAYOUTRTL)<br />
		CRect::SwapLeftRight(lpRect);<br />
}

In the world of MFC there is a function ScreenToClient(which will convert the rect), but in Win32 it doesn't quite work the same.

Right. CWnd::ScreenToClient() makes two calls to ::ScreenToClient(). This is what that article is doing, too. That appears to be the biggest difference from how the one I referenced works (aside from it being MFC).

Dynamically Increasing Arrays

Hi,
had raised a querry for this yesterday, though dint ne good ideas, so thought would share some info I found after trying out all possible things...

To create a dynamicly increasing array of objects, that is the arraysize should increase dynamically. You can follow the below steps in .NET environ

1. Create an arraylist eg
ArrayList arrayObj = new ArrayList();

2. Add the objects in arrayObj
arrayObj.Add( obj1, obj2.... );

3. Copy this arraylist to an object array of the specific class as under

ClassA[] obj1 = new ClassA[arrayObj.Count];
arrayObj.CopyTo( obj1, 0 );

Now obj1 is an array of objects of type ClassA !

Cheers!

damn !!!

you never said you were working for .NET ! WTF | :WTF:

simply because you asked this on Visual C++ forum, you got C++ answers.

if you wanted MC++ (Managed C++) code, then you should have asked this in the C++/CLI forum[^], which is dedicated to the new Managed C++ Visual C++ compiler mode...

But hey look at the bright side, all got to know some .NET info as well eh!
If my query caused some brainknocking...sorry for that!

though this forum has always helped me!!!

I'm not seeing the correlation between the question and the answer. Confused | :confused:

The code snippet that you've provided does not look like "a dynamicly increasing array of objects." It looks like one object array being copied to another. Could you not have just used std::array for this? It allows for dynamically growing/shrinking of the array.

How to paint overlay graphics

Gaboni24-Feb-06 0:57

Hi,

I want to paint some overlay graphics upon a game screen (the game works with directx). I've tried to paint directly in the game HDC, but there's a lot of blinking because the game constantly paints upon my drawing (and viceversa).

How could I paint to eliminate the blinking? Would I have to use directx?

Any help will be highly appreciated.

Do all printing into a bitmap. When the picture is complete copy the bitmap (or parts of it) to the screen. That gets rid of al the blinking.

I might be able to give you some code, depending on what kind of class you are printing into.

You could run IE using the debugger. In project settings, in the Debug tab, it says "Executable for debug sessions". Just enter the path for iexplore.exe, and then you can find the problem using the debugger.

I think it could be like repositioning code or drawing code causing the problem, but using the debugger will indeed help.

this is this.

If you get to the source, then in one of the debug windows, there is a combo-box which shows the current context. It shows the current file or function where the assertion failed. You should see down in that combobox, where your file is. Then select your file from that list, the topmost one. That will show you the exact line which caused the assertion failure. I cannot say much about it because I do not have Visual Studio right now. But look in that combobox, you will find the file, the function, and the exact line where the assertion failed.

this is this.
