Can you give more details of your problem? I did not get it exactly...

I have three list boxes that i need to update(write strings to) on the completion of a loop execution.
the problem is that i need to write to the list boxes in a worker thread
as the values to be written are calculated there.
Also the problem is i have other threads runnin that interface with the parallel port(this is inside a DLL). using AddString in the main MFC thread affects the execution of the hardware interfacing thread for some reason.
Now while writing to the list boxes using AddString my other thread does not write to the parallel port???? is there any reason why this is happening...

Try to give some free time to other threads also... 
Write a Sleep( 1 ) in the loop that fills the listbox. And let me know the status.

no no the listbox is updated outside the loop just after the loop finishes execution..
and we need to fill only one value in each list box in every thread.
|
|
|
|
|
OK... then I suspect it is a heavy calculation. You can try the sleep there.

Why? This is a recipe for disaster. A thread should not interact with a GUI component that it does not own. Have it post a message to the owning thread instead.

i have a GIF image i need to extract its R G B values from the color Palette and combine them to a one hexidecimal value .how can i convert the 3 colors of each pixel to one hexidecimal value?

I think you already have the value as COLORREF. Then you just want it print it in hexadecimal, right?

no i have 3 values one for the R value (for e.g 128) , one for the G value and one for the B value i need to combine the three values to form a hexidecimal value for the color as whole in c# language
|
|

Try this:
COLORREF colour = RGB(r, g, b);
where r, g and b are three colour components.
For printing in hexadecimal mode:
printf("%06X", (DWORD)colour);
For obtaining red, green and blue components back, use GetRValue, GetGValue and GetBValue.
|
|
|
|
|
CString str;
str.Format("%02X, %02X, %02X", rVal, gVal, bVal);
Somethings seem HARD to do, until we know how to do them.

is RGB macro of any use! since COLORREF is defined as DWORD!

Hi All,
I would like to write an application which should receive a message when the current active window loses focus. For example, consider MS-Word is active now. As soon as somebody opens IE then word window will lose its focus. At this event my application should get a message. And after sometime when this IE gets minimized I should get another message. Basically my application should be able to receive messages when different window events happen.
Is this possible? Can somebody give me some information?
Thanks,
Sandeep

He needs to watch the focus change... not the focus loss...

Do it this way,
Get the active window and store in the a variable :- activeWind.
Now keep checking the GetActiveWindow() window against the activeWind, If it differs, take that as an Event, and update your activeWind will this help you?, but there should other simpler ways
<marquee scrollamount="1" scrolldelay="1" direction="up" height="10" step="1">--[V]--
