My application requires that a certain windows hotfix has been applied in order to work correctly. Is there any way I can include this hotfix in my application install? If there is, how do I stop the hotfix from running again if a newer version of the software is installed?

Hello. I Have a listview with several items in it. How do I get the listview to scroll down when another item is added? In winforms, I could just call ensurevisible() on the item in question, and the listview would scroll, but (even though MSDN says to the contrary) there is no EnsureVisible...

I have an application that has multiple background threads that loop for tasks eg every 10 secs etc. I obviously also have my gui thread that the users interact with. In this particular market (epos) there is absolutely no delays allowed, but sometimes ( and it can be days of use before this...

I have an application that creates a number of Buttons on a canvas, and then sets them all to invisible. Unfortunately it seems that as soon as the appliaction has loaded these buttons, my cpu maxes out for a good few minutes. I know it is related to these buttons because if I comment out the...

What are the thought of you guys on the databinding in wpf? Do you prefer it or the winforms databinding that we're more used to? I tend to prefer the winforms way at present, however the databinding of properties throughout the hierarchy of the xaml document certainly does interest me...

Any chance of a wpf/ net3 area of the forums yet?

Is there an easy way to read XML from a string variable into a dataset? At the moment, I am having to write the XML from the String out to a text file, and then read in the XML from that file using the .ReadXML(Filename) method. I find it bizarre that the dataset has .GetXML so that you can...

Hi Guys Forgive me if this is easy or anything like that, I am a GDI+ newbie. I have a form that dynamically loads and displays buttons, up to 30 or 40 on one screen (it's an EPOS program) However, if i set a background image on the form, it can take up to a second or 2 for the system to...
