Is it a good idea to create an STL iterator which is noncopyable?

Most of the time, STL iterators are CopyConstructable, because several STL algorithms require this to improve performance, such as std::sort. However, I've been working on a pet project to wrap the FindXFile API (previously asked about), but the problem is it's impossible to implement a copyable iterator around this API. A find handle c...

Issues with simulating cell selection in Excel using PostMessage

Hi all, So far I've tried drag/drop motion in many applications including Visualization software (moving time slider left/right), Photoshop-Paint (drawing) etc. I need some more testing before I make sure that my system works and it failed in Excel. I'm using the code below to send the input: m.x = 215; m.y = 200 + 36 + 9 * ( currentT...

OpenGL bitmap text fails after drawing polygon

Hi, I'm using Win32 and OpenGL to to draw text onto a window. I'm using the bitmap font method, with wglUseFontBitmaps. Here is my main rendering function: glClear(GL_COLOR_BUFFER_BIT); glPushMatrix(); glColor3f(1.0f, 0.0f, 1.0f); glBegin(GL_QUADS); glVertex2f(0.0f, 0.0f); glVertex2f(128.0f, 0.0f); glVer...

Is a control tree cached after the first call to FindWindowEx/EnumChildWindows?

I noticed that if you call FindWindowEx or EnumChildWindows against a hWnd that belongs to a window that's not in the foreground, i.e. minimized, then they don't report any children. On the other hand if I first call SetForegroundWindow against the window I'm querying, and after that FindWindowEx or EnumChildWindows, they report all the ...

CodePage ID to CodePage name: GetEncoding equivalent in Delphi?

Hello all, I'm looking for a Win32 equivalent of the .Net Encoding.GetEncoding Method to be used in Delphi7. What I would like to achieve is to convert a Codepage ID (ie.: 28592) to a Codepage name (iso-8859-2 in this case). I've found a Win32 function called GetCPInfoEx, but that returns a long CodePage name, and I need the short one...

Forward declare HINSTANCE and friends

Is there a way to forward-declare the HINSTANCE type from the WinAPI without including the full (and big) windows.h header? For example, if I have a class RenderWindow which owns an HINSTANCE mInstance, i will have to include windows.h in RenderWindow.h. So everything that needs RenderWindow also has to include windows.h. I tried inclu...

::LookupAccountSid API Extremely Slow When Targeting x64 Platform (Windows 7)

During our application startup, we are making a call to ::LookupAccountSid(). When I build targeting the x86 architecture, this call is nearly instantaneous. However, when I target x64 (debug or release), the call generally takes over 40s to complete. Since this is occurring during application startup, the result is fairly unpleasant ...

Problem with Keyboard hook proc

The background: My form has a TWebBrowser. I want to close the form with ESC but the TWebBrowser eats the keystrokes - so I decided to go with a keyboard hook. The problem is that the Form can be open in multiple instances at the same time. No matter what I do, in some situations, if there are two instances open of my form, closing one...

How to include path in commandline?

CreateProcess() returns false when the commandline contains a path.I don't understand why.

The Coolest Parts of Windows API

I have noticed that there are quite a few community wikis about "Tips & Tricks" or "Hidden Features" in programming languages and APIs here at Stack Overflow. But I could not find any about my own personal favourites: Win32 API and Delphi. Therefore I start my "own" CW about Win32 API. There are (at least) two kinds of Win API users: th...

Getting lpfnAcceptEx (accpetex) to block in native C++

Hello, I've been trying to get the lpfnAcceptEX function in Win32 to block on accept. If this is not possible I was wondering if there was a flag I could accpet or some other function that I could wait on. Right now the program is simply continually creating accepted sockets with no connections behind them. Perhaps I am misunderstanding...
