Hi

Using The free VisualC++ with DGK.

I am having a frustrating time trying to sort out some irritating problems that I think are to do with a command not being completed before the next line of code is executed. Is that possible??

For example if I call dbDeleteBitmap(10) followed imediately by dbSetCurrentBitmap(0) the SetCurrentBitmap(0) does not work.

If there are some other time consuming lines between then it works!

Is there a DoEvents type command that could help?

Before you called dbDeleteBitmap(10), the current bitmap was 10 ?
Its odd tough, could you post a little app as a example?

Hi

Yes Fersis the current bitmap was 10 prior to delete.

I get the same result if the deletebitmap(10) follows the setcurrentbitmap(0) unless there are some other time consuming events between them.

I will try to recreate the problem on a small app later,(boss says work), but the segment that is causing me problems is
i=1;
while(i<11){
if (dbBitmapExist(10){dbDeleteBitmap(10);}
dbCreateBitmap(10);
dbSetCurrentBitmap(10);
dbCopyBitmap(9,10);
//draw on 10
dbGetImage(i)
}
dbSetCurrentBitmap(0);

if (dbBitmapExist(10){dbDeleteBitmap(10);}


tests if bitmap(10) exitscreates a bitmap, copies an existing bitmap into it, getImage then deletes the bitmap

Hello again!

I now have a workaround for the problem for anyone who encounters a similar thing to this one.

In my case if I use bitmap(0) before deleting the previous bitmap then all is well.

So following dbSetBitmap(0);
dbPrint(" ");
dbSync();
dBDeleteBitmap(10);
