• Visual Basic can't register Microsoft.InteropFormTools.dll

  Hi all, I'm probably doing something wrong, but I'm having a problem with the toolkit dll. The VB.net part (of the hello world sample) works fine, but if I open the project in VB6, I'm getting a 'missing reference: toolkit dll" error. If I manually try to add the reference, I get an other error : can't add reference. What I'm a doing wrong Greetz Geert Hello Paul, Thnx for the answer....problem solved. The real problem was that I use VB.NET on my Laptop, but VB6 runs in a (MS) virtual PC, so I thought I simply have to copy the "hello world.dll" and the "toolkit.dll" to the VPC, but this one failed.....but following your tips, I installed the toolkit (also) in th ...Show All

• SQL Server Removing Weekends??

• Windows Forms Form won't click - is this another change from VB4?

  Probably another stupid question (all I ever ask!). My VB4 program allowed the user to click the background of the form to alter the background picture. In VBS, I put code into form event "click", run the program and the code does absolutely nothing. Put the identical code onto a button or label and it works fine. Does this mean that VBS won't let you click the form itself (The 'click' event shows in the list of form events, so am I missing something ) Andrus42 The purpose of VB Studio is to make old programmers feel their age... Thanks for the response. In a sense it's a relief - it's VBS rather than me doing something totally stupid (makes a nice change), Thanks for the work-around - a panel s ...Show All

  I've got a simple grid (DataGridView), bound to datasource in a strongly-typed dataset  (appStronglyTypedDS).   When I populate the grid, and delete all the rows, one-by-one,  the very last row never seems to delete.   I do see  both the '>' and '*' icons in the very first column of that row and the values are all cleared.   But when I shutdown the app and restart, that last row, comes back.   Here is the code for my UserDeletingRow event handler: private void dataGridView9_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e) {   // -- just to check how many rows are in grid   MessageBox.Show(dataGridView9.Rows.Count.ToString());   // ----------- ...Show All

• Visual Basic prevent null exception from occurring

  Hi there, I'm fairly new to VB.NET and love it but I'm not sure how to prevent a null exception from occuring. I can use the Try ... Catch to prevent the program crashing but I would prefer not to use this method. Is there a way to test for this without throwing exception I need to return a blank value for objUserInfo.Properties.Item( "mail" ).Value for example if nothing is found. I'm building a string from data gathered in active directory to output to a CSV file. It seems if a value is blank then an exception is thrown.
