assume that I have some project that can support hot key and this project is running.Then I open another program for doing something.
While I'm using this program the first program will can't use hots key because now the focus is on the program that I'm using it.
If I want to make it always support hot key although I use another program.
How I do for this case?

I want to create bitmaps and save them on the hard disk.
May be i can start with 1.bmp, 2.bmp.... so on.
Basically on one webpage there is slideshow.
i want to find this window of webpage ,
I want to initiate a timer (same as the webpage interval at which slide changes) , at this timer event I want to capture the slide or web window as bitmap and save it on harddisk at any path.

One of possible method of capturing parts of HTML content can be based on the screen-capture operation, performed for maximized and on-top browser. In this case you do not need to find the window which contains the HTML content. Just save the image of the screen. You can also capture only the needed region of the screen.

For screen-capturing operations, see http://www.codeproject.com/dialog/screencap.asp[^].

For saving bitmap to a file, see http://www.geocities.com/krishnapg/bitmap.html[^] or http://www.codeproject.com/bitmap/drawing2bitmap.asp[^].

And what is your watchog supposed to do exactly ? And what is the 'resolution' you want to achieve ? (remember that windows is not a real-time OS).

A while ago, I wrote a simple little app which would look for a file in a marticular location - e.g. c:\MyFolder\MyWatchdogFile.txt". If it wasn't there, the app would restart the PC using ExitWindowsEx(), with the correct parameters set. If it was, it would remove the file.

I arranged for the Watchdog app to check for the file every minute, and my main application to write the file to the folder every minute as well.

This did work for me, however, some of you super programmers may find problems with this?

I hope this helps!

finding default application for a file.

A minor suggestion - an application I worked on created the file every minute (say), while the checking application checked every 2.5 minutes. Just a little extra buffer in case there is a small time overrun, but the creating program recovered without hanging.

What do you want to do exactly ? Execute the program to open the file ? Then you can simply use ShellExecute for that, the file will be opened by the correct application.

If you want just to retrieve the name of the app (for example), then you have to look in the registry but I cannot help you more on that.
