ok, I must be having a brain freeze here... I have a ComboBox with 6 items and I'm trying to bind the selected item to an integer value. Its not working, I suspect its because the ComboBoxItem's are strings. I don't feel like making a list in code behind just to fill this little box, so is there a way in xaml to tell the comboboxitems t...
I am trying to use this function from a COM API which enables the window to receive drops (as in drag & dop) from another application. It is pretty straightforward in Windows Forms and works: public void EnableDropSupport(System.Windows.Forms.Form form) { IntPtr hwnd = form.Handle; _comAPI.RegisterDropWindow((int)hwnd); } But I...
I'm working on adding a Flash app to a Surface application. It looks to be working just fine (overlaying the Flash app with an almost transparent Surface window to catch the Contacts). However, if I want to call a Flash function in my SWF (using .CallFunction), I get a E_FAIL exception. It is suggested that a callback function in the SW...

I have a TextBlock that is in a Grid that is an ItemTemplate for a ListView. I have the items so that they grow when the window is resized, but I cannot figure out how to have the TextBlock be limited to that size.

I have a GridView in a ListView contained in a ScrollViewer element. I understand WPF draws only the visible data at runtime, for example on scrolling grids only the visible rows are drawn initially - my problem is that I don't have as much power as on the desktop on a portable device I am developing for, so my WPF ListView - which scr...

This part will be a room correction algorithm which currently takes about 10 seconds per channel to run in Matlab. It has to be written in C/C++, since it might be ported to a DSP late...
Now I am aware that I probably need to use a ListBox and can use the GroupStyle stuff which completely 100% fits my needs. Only thing is that I've been told that: "Whenever a "GroupStyle" is set on the control, the panel that layouts the items changes from VirtualizingStackPanel to StackPanel (this is a hack in MS code)..." I will nee...
Currently I'm using a System.Windows.Media.DrawingGroup to store some tiled images (ImageDrawing) inside the Children-DrawingCollection property.
