• Windows Forms ClickOnce on a locked down Terminal Server

  I've been asked to get a ClickOnce application working on our Windows Server 2003 terminal servers. Note: I am not the application developer - just the guy trying to get the app running.  I can make suggestions to the developer but they are a third-party. Some background : The terminal servers are load-balanced and publicly accessible (no guest access) so we have them locked down; although not as tightly as *I'd* like...  ...Show All

• Visual C# Merging namespaces as one

  Is it possible to merge multiple namespaces as one The reason I want to do this is because I want to inherit someone elses control, but use my own namespace. Using my own namespace stops the UI design tools from working. What I need is to be able to make C# think my control exists within the other name space, while still existing in my namespace. Maybe I'm asking for to much. Namespaces exist to create seperat ...Show All

• Visual Studio Express Editions Active X Problem

  Newbie alert...Apologies in advance. I encounter problems w/ applications that appear to point to an issue with "Active X" e.g. Norton will not fully load, Turbo tax will not finish, Logitech VideoCall will not work. The common symptom is that the app reaches a screen where nothing appears inside an area where data s/b. The apps are working, no freeze up, no errors.

On Dispose of the form, we call ClearBindings as described in: http://msdn.microsof ...Show All

  I apologize if the answer to this question is obvious but I am getting a new machine (64-bit CPU) and I want to avoid as many problems as possible. I find it confusing that some of the System Requirements show Windows XP SP2 but do not show x64 explicitly. I intend to work with the Feb CTP, Visual C# Express, 'Orcas' and the VS 2005 Extensions; and possibly the SQL Server 2005 Express. I would appreciate any guidance as to whether I sho ...Show All
