• Visual C# Dynamic assignment of Data Objects

  I'm trying to make all of the assignments dynamic in my MDI application. The MDI form takes care of loading the connection string. Opening a new form child, My app reads in a text file, processes each line and writes records to a temporary table. The datagrid then connects to this temp table. How do I open a connection, insert records and then finally bind the data grid I can see how to bind the grid to an adapter/dataset but I need to insert before. Thanks, Mike Re 1) Use 2 seperate DataAdapters. Since the various commands of the DataAdapter will store the query to fetch the data. Hence if they are tw ...Show All

• .NET Development Asp.Net codebehind files

  Can two web form have a single codebehind file. Yes, but the IDE does not like it. It would be better to create a class that derives from Page and then derive each of the web form code-behind classes from your derived class. So for example a page named Orders.aspx and a page Customers.aspx would have code-behind classes named Orders and Customers respectively. Both Orders and Customers classes would derive from your CustomBasePage class instead of Page. The CustomBasePage class would derive from Page. All of the code that the pages share could be placed in CustomBasePage and inheritance would let both pag ...Show All

• .NET Development Suspending the main thread from an event handler, given Thread.Suspend() is deprecated

  Since Thread.Suspend() is deprecated (and that seemed like my best bet), I'm trying to find a way to solve a problem I've been having. Essentially, I've got code running in a main thread, and event handlers handling events occasionally. What I want to do is pause my main thread whenever an event handler fires so that only my event handler executes, and the main thread waits until the handler is done to continue processing. Does anyone know a good way to do this Thanks! It already works that way... Event handlers that are activated by the main thread execute on the main thread. Event handlers invok ...Show All

• Visual C# & Operator

  What exactly does the & operator do I am trying to convert the following to VB.Net: uint x = 50000; short y = 0; y = (short)(x & 0xffff); Thanks A single & is the bitwise AND operator, so ANDing 42 (101010 in binary) and 56 (111000 in binary) you would end up with 40 (101000 in binary). In VB.NET, that code would look like:         Dim x As UInt32 = Convert.ToUInt32(50000)         Dim y As Short = 0         y = Convert.ToInt16(x) & &HFFFF Just for note, the & in &HFFFF is required as ...Show All

• .NET Development Installing Framework 2.0 has made server unstable, trashed old COM components

  We are running Server 2003 for our critical server applications.  We have been updating a number of core software pieces to VS2005 / Framework 2.0. This software is installed and pretty much working as it should. The PERPLEXING issue to me is that I have antique VB6 COM components that are failing after adding Framework 2.0 to this server. Usually when the component is done after a lengthy process, and is returning to the caller. The VB6 component seems to have completed successfully, but the exception "Object variable or With block variable not set" is being thrown to the calling script. It apparently is thrown to ...Show All
