This won't work when ActiveDesktop is enabled. You need to use IActiveDesktop COM object to solve this.

1. From the look of my desktop, I dont think I have ActiveDesktop enabled. How do I confirm if it is enabled?
2. Does the IActiveDesktop COM object's way of setting the wall paper help in both the cases - ActiveDesktop is enabled and disabled?
3. FYI, I downloaded Virtual Desktop manager from http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx. I can change the wall paper in a desktop, but when I switch between desktop it doesnt seem remember and restore the wall paper that I changed. Have you used this, any idea why it doesnt work, is it a bug?

thanks!

Getting Hex value from Edit box ?

31-Jan-06 0:32

Thank u very much

Hi,

I have a dialog application where user enters hex values in CEditbox.
Is there a editbox where we can create a member variable of type HEX??
for CEDIT, only int, long, byte etc are possible but not HEX.
the hex value can range from 0x00 to 0xFFFFFFFFFFFFFFFF
in this case.

Any clues on how to do this???? Confused | :confused:

Sub class CEdit and make a CHexEdit for yourself.

I thought about that, but not sure of how to do that. Is there a code I can refer or has someone done something similar to this?

I did check that.
It validates the user entry and makes sure that user enters valid hex code, but does not solve my problem. It does not have a member variable which can give me hex value.

30-Jan-06 23:54

Now common man...

If you have the hex code in the edit box can't you just get the text from the text box. That's all you have to do. Lol Hmmm | :|

There are hordes of articles in CP related to CEdit. Just search for them trust me you won't be disappointed.

Actually it says it will do that but it is missing several key points.

there's no particuliar type to store hexadecimal values.
the answers of Owner Drawn are good enough. if you'r not satisfied, please detail the points you need help on, because nobody will do the whole job for you...
