  Hi. I want that you think with me... When i put a try-catch exception handler block in an application what i expect from it i expect that it will handle the error and begin the normal flow of the application. Now, you aswer me, why it doesn’t work in this scenary : I have one Form1 (Project > Add New > Form, nothing different), and another Form2 and one Form3. i’m proud of my creativity for names. Form1 : private void Form1_Load( object sender, EventArgs e ) { try { new Form2().Show(); } catch (Exception ex) { MessageBox.Show("Error calling form 2" + ex.Message ...Show All

• .NET Development get an URL from an ".lnk" shortcut

  Holla Again, I'd like to know how i can get the url from a shortcut. thanks a lot; Internet shortcuts have a .Url file extension and are just Ini-like text files.

• Smart Device Development Updated images for Windows Mobile 5?

  Does anyone know when or if the Windows Mobile 5 images included in the Pocket PC or Smartphone SDKs will be updated I suspect the versions in the SDKs are not the same as the versions included with WM5 devices. Thanks, Frank The SDK has Magneto AKU0.0 version and the most recent AKU is 2.1. Is there something in particular that you need out of a later AKU There are currently no plans to release 2.1 (the volume of changes is not high between the two versions), but that can change if there is customer demand.

• SQL Server SET IDENTITY_INSERT

  We have created an "AdminUser" with the bare minimum rights for the activites it will need to do. One thing the "AdminUser" will need to do is a "SET IDENTITY_INSERT ON/OFF". I understand that for this user to be able to do this they will need ddl_admin rights. But that gives them all kinds of permission that I don't want this user to have. Is there a specific permission I can give the user so they can do the "IDENTITY_INSERT" I tried "GRANT create table to AdminUser" but that didn't work. I tried "GRANT alter any database DDL trigger to AdminUser" but that didn't work ei ...Show All

• Visual Basic Drag and drop between VB 6 app and VB.NET app

  My client is using a migration approach whereby they are only migrating small pieces of the application at one time - using COM interop to handle the integration until all of the pieces are migrated. One of the pieces that has been migrated needs to be able to drag and drop onto a form containing a VB 6 User Control that is using OLEDragDrop internally. Is there any way to get the drag and drop to work between VB 6 and .NET Thanks! Since there are quite a few people who have reviewed this topic - I thought it worthwhile to post that this actually DID work. We have successfully implemented drag ...Show All

• SQL Server raw file source avoid bad data?

  I want to have a data flow like this: 1. raw file source 2. validate data or conditional split 3. sql server destination there is some bad data in my raw file.  by bad data I mean datetimes that are out of the range that sql server can handle. this should be simple right so debugging script components does not work nice. all the time I have wasted with integration services already. I could have hand written a console c# app to to the same thing I was trying to do with integrations services. I think I will wait for integration services 2.0 by that time it might be actually usefull. ...Show All

  I defined a report through the Development Studio of SQL server 2005 which has got a grid and a chart in its layout.
