• Visual Studio Express Editions database saga

  I am at my wits end. I am trying to create a program that will add users to a database. I have read the various posts regarding the output file and have changed the Copy To Output File to Copy Never. I have also tried Copy If Newer. The database still does not retain my changes/additions. The code I have used is shown below. Code Here... Private Sub AddUser_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddUser.Click Dim newUserRow As Database1DataSet.Table1Row newUserRow = Me.Database1DataSet.Table1.NewTable1Row newUserRow.Name = nameBox.Text newUserRow.Password = Password.Text Da ...Show All

• Smart Device Development infrared!

  Hi. I want to be able to send data (hex codes or whatever) using the infrared ports. I have imported the System.Net.Irda reference and able to access the IR classes. However, I do not wish to connect to a device but rather send data. The device I am sending data to will be a dumb device really, just as a "reciever"... this can be a remote control recieving box or a TV IR reciever for example. IS it possible to do this how I cannot seem to find a way in the .NET classes as it seems you have to connect to the destination then write data to the stream. Thanks! You will not be able to communicate with a TV IR receiver through your standard ...Show All

• SQL Server Port 1433

  Hi. I'm trying to deploy AdventureWorks sample reports on the local server. Prior to opening the solution file in BI Dev Studio, the data connection does have a red cross on it in the closed state.

• Visual C# Access Web Form member from it’s hosted windows user control

  Hi. I have a web app that uses a IE hosted windows user control. I would like that, somehow, lounch an external event from that hosted control that I could catch in my web form’s code behind or set a web form’s member value. Does anybody know how to do that I would appreciate any suggestions! Thanks in advance! First off you need to define your interface. This is a simple interface declaring the events you will fire, and any properties/methods you will access from the web page. It needs to be visible to COM, so use the following as a template: [GuidAttribute("1F98211C-7A71-4588-8D4A-AD85CA80BAE7&q ...Show All

• Visual Studio 2008 (Pre-release) DLinq Extensibility for Custom ADO providers?

  As we're thinking about writing our own ADO provider library (connection, command, reader, adapter etc.) I was just wondering how extensible you are planning to make DLinq and how it will fit in with the current ways of extending ADO. Any pointers to documentation on the subject would be very much appreciated. Thanks, Trev. I am not sure I understand the specific aspects on extensibility you are talking about. Here is what we have and are planning: What we have in the preview: 1. Interop with ADO.NET SqlConnection 2. .NET framework transaction model - that is *the* transaction model for DLinq and he ...Show All

• .NET Development Calling the GC.Collect method

  I have a code like this : public void SetFrmLoginNull() { frmLogin = null ; GC.Collect(); } This method is in FrmMain. But when i run a code analyzer from some tools i have, it's said that i shouldn't explicitly call GC.Collect(); b'cos it had side effect. I just need some comment from you all regarding this topic. Any Comment You should not call GC.Collect() yourself, because it has indeed a negative impact on performance. I think you should only call it, if you know that you've allocated a lot of memory that is not used / referenced any more at the time you call gc.collect, ...Show All

• Visual Studio registration of COM dlls fails in dynamic clearcase views

    Hi all, we have a problem, since we migrated from VS2003 to VS2005. Our project contains several COM DLLs, but the registration of these DLLs fail with the error message: error PRJ0019: A tool returned an error code from "Performing registration"   Registration on the command line also doesn't work. Our build runs in a dynamic clearcase view. When I copy the build output to local harddisk, then registration succeeds. It also works, if I use a snapshot view, but our build process requires a dynamic view. When I build the DLLs using VS2003, there's no problem registering them in a dynamic view. The a ...Show All
