• Windows Forms Testing Methodology

  I was wondering if the experienced developers out there would mind sharing their thoughts on how they test their critters.  I'm currently planning on creating some test harness' so that I can write some nunit tests, but I can foresee some potential pitfalls related to code access security etc.   What I'd like is: 1.  If you have some code out  ...Show All

• Windows Forms How do you refresh data bound to a DataGridView

    This should be easy... but I don't know how to do it. I have created a DataSet that is bound to a DataGridView so that the DataGridView displays the data in my DataSet.  If my DataGridView is called dgvStudents, the following code DOES NOT do the job: dgvStudents.Refresh(); I can see the grid itself flash and refresh(), but the data behind the grid is not being refreshed, so new items in the database (added by another process) are not being displayed in the grid. How do you do this   Possibly I should post this as a new thread but I believe I'm running into a similar situat ...Show All

• .NET Development how to check if datetime in SQLDateTime range

  I want to validate some dates. I was just using datetime.parse but I can still get a sqldatetime overflow error if the date is not in the permitted range. How can I check for this The SqlDateTime data type has static MinValue and MaxValue members, which return the minimum and maximum SqlDateTime values. So you could convert the string to a DateTime, and then use the static MinValue and MaxValue properties to write code like... DateTime mydatetime = ... if (mydatetime < SqlDateTime.MinValue.Value)   MessageBox.Show("Too small"); else if (mydatetime > SqlDateTime.MaxValue.Value)   Messag ...Show All

TAPI: After initializing TAPI and veryfing the device's capabilities I made the following call: phoneSetHookSwitch(hPhone, PHONEHOOKSWITCHDEV_SPEAKER, PHONEHOOKSWITCHMODE_MICSPEAKER).

• Visual Studio Team System Portal Documents CheckIn Checkout Via TFS Client

  Hi, I have a question regarding Documents checkin and checkout via TFS Client. As you know, methodology docs are created on the Team Portal. Document checkin checkout mechanism works perfectly fine if you perform it through the portal. But the problem is, we can not perform the same exercise in TFS Client. It is not possible to checkin and checkout a document and put your comment related to it if you perform it in TFS Client. You can save a document in TFS Client but it only creates a new version of the document without any comment on the portal. We need to perform checkin – checkout mechanism of a document in TFS C ...Show All

• Visual Studio Express Editions Winsock Socket Help

  Are there any premade multisocket classes All I have seen are ones that accept one connection. Are there any that allow multiple ones Are we talking about TCP If so, the programming model is that you create a socket that listens to incoming connection. Each time someone connects to your socket, you call AcceptSocket or AcceptTCPClient and get a new socket where you can communicate with the client. Check out TCPListener and TCPClient respectively...
