You may create a picture control and set the bitmaps to it with the particular time stamp

may you will get any idea from it

and for conversion of the bmp to jpeg see the following link

Knock out 'T' from CAN'T
You 'CAN' if you think you 'CAN'

You need to convert bmp files to jpeg or you need to create video file?
Can you be more specific store each converted jpeg file to a new folder.?

Puja,
Set a timer, have a picture control.
name your jpegs as jpeg1, jpeg2..... jpeg1000

for each interval play next form the jpeg name and put it in picture control
it may have movie effect.

if you want to create movie with your jpeg files you can use AVIFile Functions
but you need to convert from jpeg to hbitmap and then size output file is big because use from bitmap

also I suggest see MCI Functions maybe it is some helpful to you

You can solve it by setting a timer of a small delay on selection change and processing the change in the timer event. Notice that this timer should be deleted first in the OnTimer.
Eg.
OnSelChange()
{
SetTimer( IDT, 50, 0 );
}

OnTimer(UINT id)
{
if( id == IDT )
{
KillTimer( id );
ProcessSelection();
}
}

Hi,
this seems to be one option but then again there is perfomance problem.
i want to avoid calling the calculation function which is bulky for each items. it will be batter to call it in one struch after all the items ater is changed due to some user interaction.
can you suggest some messages which will be trigared after all the item change messages are send?
thanks in advance

Hi ,

Maybe this will help you :

void YoutClass::OnItemchangedListCtrl(NMHDR* pNMHDR, LRESULT* pResult) 
{
	NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
	if(pNMListView->uNewState)
         {
           //Do whatever you need here
         }

With best regards,
Eli

hi..
thanks for the suggestions
but there are problems ..i am using the
void YourClass::OnItemchangedListCtrl(NMHDR* pNMHDR, LRESULT* pResult)
function currently to know the change of items state. but here when user select a huge no of items using the shift + end key or using some other key insted of doing it after all items are changed we can do it only one by one.This will afftect the performance . it will be batter if i can track some message which is trigared after all selection changes are domne.
Is there any message which is faired after all selection related changes are done?
please do help ..

renaming you .dsw file will not work..
try this
in the visual c++ ide.
go to Project > Settings.
in the tab control select "Link" tab.
here you can see a section called "Output file name"
change the output file name here. you can give what ever you want...

^-^
