It's a C++ MFC app that I am developing in. Basicly the loop snippet looks something like this; pElem is a pointer to an IHTMLElement iProg is an integer that contains a progress bsText is a formated BSTR that contains the string to put in the innerHTML [code] do { iProg = GetCurrentProgress(); ... //string formating to put number into BSTR. e.g. "10%" pElem->put_innerHTML(bsText); }while(iProg != 100) [/code] The code works except that the display only updates when I move the mouse over the embedded IE control

Sitting in a tight light probably isn't a good idea. Try calling UpdateWindow() on the View. Neville Franks, Author of ED for Windows. Free Trial at www.getsoft.com

Hi, Yes i already tried that and it didn't work. If you think that being in a tight loop will be a problem how else could you do something that needed to be updated often. Another thing that i forgot to mention is that this happenes in a different thread than the IE Windows message loop. Ceri

There are various problems doing GUI stuff from secondary threads with MFC. I would try doing the updates from the main thread. In the secondary thread Post a message to the main thread and add a Message handler and get it to do the work of updating IE. That should fix it. Neville Franks, Author of ED for Windows.

Done a postmessage with a custom message and it worked fine. Thanks. I think that is a bit silly mind, I think that the message loop is a little slow. Although it's OK in this case. Ceri

But I haven't tried updating the HTML control this way. You might want to through in an UpdateWindow(). Or maybe your tight loop is using too much CPU. ;) Neville Franks, Author of ED for Windows.
