SSIS VB Script Task Inside a For Loop Container

Hi all, I'm learning SSIS, so sorry if this question is too primitive. I added a For Loop container to control flow and then added script task inside the For Loop container. I also added a variable and initExpression @x=1, EvalExpression @x<4 and AssignExpression @x=@x+1 , and added a simple script for testing System.Windows.Forms.MessageBox.Show (Dts.Variables("x").Value.ToString()); The exact same script and process work fine when I use C# , but in Vb.net it only displays the first increment of x and SSIS keeps running without displaying message box for x increments

Are both of the script tasks in the same package? Just wondering if they are sharing @x

Thanks for the reply , but as I explained the issue I have is when supply a variable from outside. C# code works as expected but VB.net only displays the first incement of variable x.

Yes and you also said that you used the exact same code for both. With the two different languages that can't quite be true. So how about posting more info like your actual code and people can post better answers for you.

Here is a working example of both languages. Notice the subtle differences. I have these running in a "test" package in sequence but they are not utilizing a variable from outside the script. I leave that as a final exercise to the op. First C# public void Main() { // TODO: Add your code here int someX = 1; MessageBox.Show(someX.ToString()); while (someX < 4) { someX++; MessageBox.Show(someX.ToString()); } Dts.TaskResult = (int)ScriptResults.Success; } And now VB Public Sub Main() ' ' Add your code here ' Dim someX As Integer = 1 'MsgBox(someX.ToString()) While (someX

In VB.net System.Windows.Forms.MessageBox.Show (Dts.Variables("x").Value.ToString()) In C# System.Windows.Forms.MessageBox.Show (Dts.Variables["x"].Value.ToString()); for both initExpression @x=1 EvalExpression @x<4 AssignExpression @x=@x+1 As I said I don't do anything fancy just trying to test how we send a variable from outside and see how SSIS loops through the code Both codes are suposed o display messagebox 3 times. C# code works fine , but VB code only displays first message box with value 1 a,d keeps running without showing additional message boxes.

You see the code I have posted. Start with that and get it to work. Then modify to use the external variable. It isn't a lot different. Not seeing your code, I can't see where you have made the mistake.
