Skining framework and CComboBox

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello

I have a MDI project using the Codejock skining framework and i encounter some problems when using a CComboBox.

Although I know it's not good practice I am forced to fill a lot of ComboBoxes (many times) with a lot of strings (15000+). The problem is the filling is very slow  then using the skin framework. 

I attached a test project, a simple dialog project:

20090205_050056_combotest.zip

when not using the skinning sytem the time for loading 15000 items in the combo box: 703 miliseconds

Then just add this line:

XTPSkinManager()->LoadSkin(_T("Office2007.cjstyles"));

and the time for loading is 12062 miliseconds. That's huge!

I give my user the possibility to filter the combo so even if a only have about 2000 items it is still unacceptable to go from instantly to 1.5 seconds...

Release version isn't better either. And this is on my quad core Xeon machine I don't even want to imagine what happens on slower machines. I'm working on this for the  last week with no success. I absolutely need both things working.

	Hi, For such long operations always use SetRedraw API: pControl->SetRedraw(FALSE); ... pControl->SetRedraw(TRUE);
