Hai all

I'm using the active desktop Interface to get the current destop item count using the function GetDesktopItemCount(&count,0);

But on my desktop there is more than 10 things and the count value got by GetDesktopItemCount() is '1'.Why is it so.

Please reply.

My OS is XP.

Thanks in Advance
Robs

You can use a mutex object.

How can I simply read/write specific values from an Excel spreadsheet (e.g. case at Row2; Column2) using C++?

That's all what I need to do and I'd rather not use the cumbersome classes that I've seen posted here.

Help please, I've been stuck on this for ages!! D'Oh! | :doh:

Using Excel Automation is by far the easiest method.

When the EOF is reached, the Read() function will return 0.

You can do it in a dialog based application. Use two edit controls to get the data.

But what do you meant by "separate window in a grid"?

Sorry I wasn't clear about the grid part...What I meant was like suppose it's the location of two points then to represent it on a X-Y plane...

Means you need to show a point in graph like control? Then you may have to go for a custom control.

If this window is to be created at runtime, use CreateWindow().

Playing AVI directly that is inside in a bigger data file

Hi,

Is that possible to use MCIWnd or any other Lib to play an avi file that is part of a bigger data file and the starting disk offset is known ?

For example I am trying to make this

copy /b text.txt+movie.avi final.dat /b

This creates a new binary file that is the joint of the files text.txt and movie.avi. I know that text.txt is 10 bytes long and in the 11th byte it starts the AVI movie. Is that possible to play it directly (without extracting it) within final.dat ?

Regards,

sdancer75
