How can I get the selected window(s) handle to send our user defined message. I need to send some own message, before OS sending minimize/maximize message. Is it possible to get the handle please help me. Thanks in Advance Re: how to get the window handle in windows task manager? Arsalan Malik6-Sep-04 2:24 Arsalan Malik 6-Sep-04 2:24  Use FindWindow or FindWindowEx function in API. This will take window class and name as parameter, and will give you handle, if found. You can find window class using Spy++ utility, that comes with Visual Studio.

Passing CWnd from the CDialog, the generic class constructor creates the Static controls at run time (constructor call, .create(...)). It (seems) to work fine, since the text is displayed in the dialog. My Problem now is: How do I handle messages for the static text controls, e.g. mouse_move, mouse_down. Help would be greatly appreciated Sorry, if this is the wrong place for this, not sure if it belongs in managed c++ Re: Message Maps in classes mastishka6-Sep-04 2:02 mastishka 6-Sep-04 2:02  Ok my friend for getting any messages on any control you have to go through subclassing, by that you can get complete control over any control. See artical named "Windows Message Handling - Part 4" by "Daniel Kopitchinski" in "Dialog and Windows Programming topics" of CodeProject.

OVERLAPPED Serial Communication louis6-Sep-04 0:04 louis 6-Sep-04 0:04  I am currenlty going through a former colleague's code who used OVERLAPPED I/O to receive asynchronous serial data. The program first declare a pointer variable pRxBuffer which will contain the received data. It then creates the port, then creates an overlapped event, and then reads the port which contains no data. The program then waits indefinitely using WaitForMultipleObjects function. When the data arrives, the pointer variable pRxBuffer is immediately filled with the received data without using the ReadFile fucntion (or so it seems) and prior to calling the GerOverlappedResult function. If this makes sense to someone, can you please explain to me how this is possible? How is the data transferred to pRxBuffer. Thanks Re: OVERLAPPED Serial Communication soundman326-Sep-04 1:28 soundman32 6-Sep-04 1:28  That's how it works. Basically, the initial ReadFile tells windows: here is a buffer, and here is the overlapped event is where I want you to tell me when you've filled the buffer. There should also be a check on the return of ReadFile to check if the data has already arrived (which is possible).

I can't seem to find anything on it on the web. Re: How to write a plugin for IE User 66586-Sep-04 1:05 User 6658 6-Sep-04 1:05  Search for "Browser Helper Object" or "BHO". You will find some examples here at codeproject.com as well. regards modified 12-Sep-18 21:01pm. Re: How to write a plugin for IE Anonymous6-Sep-04 20:50 Anonymous 6-Sep-04 20:50  Here's a great article to start with (if you're familiar with COM). If you're not, you might want to brush up on COM before tackling a BHO project. You're always free to develop a BHO in raw C++ however, ATL is the preferred method. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwebgen/html/bho.asp Does this answer your question? or, did I completely misunderstand your post.

Re: Plss!!!Help!!!! in parallel interfacing in visual c++ soundman326-Sep-04 1:36 soundman32 6-Sep-04 1:36  If you are using Win95 or Win98 then you may be able to do it using assembler. If you are using NT/2K or XP then things get more tricky. Basically, you need a driver to allow direct access to the parallel port (which is not normally allowed). I used one ages ago, which you could give a range of I/O addresses, and you could read or write to them via a DLL. I can't remember what it is called, but Try googling for "parallel port access windows driver". Re: Plss!!!Help!!!! in parallel interfacing in visual c++ CoreyCooper6-Sep-04 14:02 CoreyCooper 6-Sep-04 14:02  I've sucseffuly used a general purpose device drive called "TinyPort". It's good, but it warns you that it is relativly slow, being that it is general purpose, not specific to a device.
