• .NET Development raising an event via reflection

  Using reflection is it possible to check if an event has a handler and more importantly raise that event. I have a string with a value of the event and the object instance which I need to fire. Thanks for the VB example. Seems a lot of folks are stuck on this issue. Here is a c# flavor of it. public event EventHandler<EventArgs> MyEventToBeFired; public void FireEvent(Guid instanceId, string handler) { // Note: this is being fired from a method with in the same class that defined the event (i.e. "this"). EventArgs e = new EventArgs(instanceId); MulticastDelegate eventDelagate = (MulticastDelegate)this.GetType().GetField(handler, ...Show All

• Windows Forms DataBinding a TextBox to a field from a related table.

  I have a Master/Detail table related with a relastion. The Parent Grid Shows the Master records, and the Detail Grid shows the related records as it should. The Detail Grid is on a tab, and the second tab is a number of TextBoxes that I want to bind to the detail table so it can be edited. The databinding is done with this line of code: this .txtTask.DataBindings.Add( "Text" , this .DataSet, "Customer.relCustomerToTask.Customer" ); No error is thrown, but the textbox fails to show any data, and does not seem to actually be bound. I cannot find a reason for this not to work as expected. Like I mentioned above, the grid to show the detail table works fine, so it should be a simple matter to bind the textbo ...Show All

• SQL Server How to hide subtotals if only 1 row in group?

  Hello, I have established a group so that I can provide subtotals following the presentation of the group's detail rows. I'm finding that many of the groups have only one row and my subtotals just echo what was already presented on the detail line. The overall effect is confusing to the user and a real vertical space-waster. Can someone give me a technique or expression for hiding subtotals when the group size is 1 but showing subtotals when the group size is >= 2 If I hide the group when the group size is 1 row then the one detail row is hidden as well, no Thanks! BCB But I just want to hide the subtotal line. Won't your approach hide the one detail line that belongs to the group as wel ...Show All

• Visual Studio Team System changing TFS workgroup to TFS trial

  Hi everybody, I've installed TFS workgroup edition in over company, And so far it's works OK (haven't added a lot of code to the source control but then again our server does not meet the minimum requirments :) The problem is that in the next couple of weeks we are going to hire another programmer and we already use 5licenses.

• .NET Development How to empty a table in a database

  Hi, I use VB 2005 Express edition. I want to empty a table in a MS Access data base and set the primary key to 1 for the next entry. How can I do that Thanks! In your CompactDatabase statement there should be a space between "Data" and "Source" in your source database connection string. In addition, if I recall correctly, the destination file cannot be the same as the source. You will probably need to specify a different destination file name. If you want to retain the same file name you can delete the source and rename the destination after compacting. ...Show All

• Visual Studio Team System Can I use load tests to get these results?

  Hi, I've been trying to figure out how do use the load tests to achieve what my team needs. I've asked different questions and got very usefull answers, but still can't quite figure out how to get the results we need. So, I decided to just describe what we need and hopefully someone knows how to do it or will send me in the right direction. We have a web application that we host for our clients. We suspect that there's a memory leak in one of the pages. Over time, our .Net application has to be restarted and we suspect that it's due to the memory leakage. We would like to use Visual Studio load tests to find out the relationship between how many times this page gets loaded and how much memory is being used (to see that the more the p ...Show All

• SQL Server Audit All SQL Queries against all or specific databases

  Hello, I have a problem. I suspect a certain user in my company is using the SA account to log into Databases and run queries(query analyzer) to gather information this user is not suppose to view. The problem I have is this is an IT person so they know the SA password. How can I log specific or all queries run against all databases/tables/fields to find out exactly what this person is doing/seeing Or if there is an alternative to find out this information Please advise Hi, Well they are only running these in Select statements. These are not stored procedures. So I am assuming the SQL profiler would work with capturing the data on the database / hostname /application, etc. If you have a good ...Show All
