• Visual C# How to delete a control during runtime?

  Hi, I would like to know how to delete a control when the user presses the Delete key on the keyboard (For example, there is a label in the form, and the user clicks on it and presses Delete). I was trying to use the KeyEventArgs but it always gives me an error message stating that it is not set to an instance of an object.. There is no real way of finding out which control was clicked upon in runtime mode - and besides you cannot select a label control during runtime AFAIK however to remove the control in an easy way: this.Controls.RemoveByKey( "ControlName" ); you can perhaps go through each control in the Controls collection and see if the control has focus, if so, remove it with ...Show All

• Visual C# Creating and Displaying graphs and charts in C#

  I was wondering if there were any prebuilt chartting functions in VS2005 or the .NET framework as a whole Or would I be required to purchase one of the many 3rd party tools out there If the latter is the case, have you got any ideas for a quality, clear-display, student-friendly version. Thanks. You could use Crystal for generating reports or Visual Studio Tools for Office for linking Microsoft Office. If those aren't right for you, you should try finding a third party tool. There are some open source solutions. - Charlie ...Show All

• .NET Development FileLogTraceListener class - implementation ?

  Hi friends, Anybody tried using the FileLogTraceListener class for data logging to text files I've been reading this and getting more confused. If any noble, generous soul can explain it to me or better still share the code snippets to make it work I would be highly obliged. Thanks, Kunal I would strongly recommend not creating FileLogTraceListener in your code when you need them, but to follow the standard method and create a correctly configured TraceSource -- e.g. for the example below TraceSource ts = new TraceSource("mytrace"); [or VB syntax]. FileLogTraceListener is not intended to be created directly in the code, and I think it would create more problems in the future (and less flexibility), than doing ...Show All

• SQL Server Copying a report to another report in same solution

  How can I copy a report and all its supporing queries and make a duplicate so that report1 and report2 are duplicates. Report 2 will be little different than report1 but the basic queries and parameters will all the same. I can then edit the report layout to what the new report will look like. I do not want to have to cut/paste one object at a time. Is there a better way You can do this directly from within Visual Studio. Right click on the report you want to copy (in Solution Explorer) and select 'Copy' (or you can just highlight your report and hit Ctrl+C). Then press Ctrl+V. This will create a new duplicate report with 'Copy of ' prefixed on the report name. Hope this helps. Jarret ...Show All

• Windows Forms How can I get tableadapter to process dynamic sql 'select' queries?

  Environment: Sql Server 2005 express, VB 2005 express, .Net 2.0 I want to get a tableadapter to execute a query like the following: Select * from dbo.table where lastname > bbb and lastname < ffff Each time I execute the tableadapter, I want it to use the current query I have constructed for its retrieval logic. Essentially I want to provide the whole query and not just a portion of the query to the tableadapter. Is this possible/practical or do I need to abandon the tableadapter and look in another direction TIA Gary Thanks for this solution.. It works great. I was using TableAdapters, and bringing back all data, then running a 'Select' statement against the DataTable... Unfortunately this was f ...Show All

• Visual Studio 2008 (Pre-release) Problem with MEX WSDL

  Hello, I was trying to use an WCF web service from SQL Server Integration Services (SSIS). This web service returns an array of int and an array of a data contract. The WSDL is provided by MEX. There are 4 schemas xsd0-xsd3. xsd1 imports xsd2 and xsd3. And the WSDL imports all xsd files. The problem is that SSIS doesn't like the double imported schemas. So It doesn't work. After manually editing the wsdl and removing xsd2 and xsd3 it works. Are the twice imported schemas a bug Or is this standard conform Thanks, Uwe A Web Service is used by SSIS with a WebService Task: Define HTTP connection to URL for the Mex-WSDL: ... wsdl.
