• .NET Development X509 key not loaded correctly for FTPS server authentication ?

  I have written an FTP service in VB.NET. Am attempting to add SSL authentication. I believe it is either not doing the handshake correctly, or else it does not like the way I loaded the server certificate.  Let me paraphrase the salient portions of code to show what I am doing, and the resulting exception: Public SSLCertificate As X509Certificate SSLCertificate = New X509Certificate("D:\TEMP\MyPrivateKey.pfx", "myprivatekeyspassword") Priv ...Show All

• Visual Studio Team System Not Getting "Test" Menu after installing TF Client

  I'm sure I'm not doing something fundamentally simple, but after installing the "Team Foundation Client" from the Beta 3 Refresh MSDN December 05 shipment I get no "Test" menu in Visual Studio. My understanding is that creation of unit tests and everything else test-related is done from that menu. Should I be installing something else, or is there a way to get that menu to appear by switching on some setting ...Show All

• Windows Forms Paint Event Problem

  I have a Windows application that overrides the Paint method to change the presentation of the form. Basically, it paints a red border around the edge of the form. I also have a couple of panels that fill up the form. One is docked to the left and the other fills the remaining space. Each of these panels also has an override to the paint event. The overrides are in the Form1 class. The problem: The project solution compiles and runs just ...Show All

  I am making my first steps in C#. I am used to another object oriented language (VDbase plus) but not .NET. I designed a form under Windows Applications. There is a button on it.

• Smart Device Development Updating UI from thread: Control.invoke()?

  Hi, I'm experiencing some difficulties writing my first application for pocketPc. The program should run on a dell axim x51v with windows mobile 5.0. (I'm using vs2005 professional.)

  Hello - Form f = new Form(); ... DialogResult dr = f.ShowDialog(); ... After retrieving the dialog result, how can I increase the speed at which the closing form dissapears and the underlying (parent) form refreshes/repaints itself It appears as if panels dispose of themselves one at a time...
