I have an app that allows a user to type in code that can be executed much like vba code in the office world.I currently execute this code with the Proprietary Dexterity code used with MS Dynamics - GP.However, my users need to be able to run outside the Dexterity world.The easy answer is to allow them to type in vb scripting or vb code instead of dex code.However, I can't find an easy way to dynamically execute their code within my methods.CodeCom looked like it could be the answer, but If i'm reading it right, I would have to know what libraries the user is using in their code for vb.Thus, I thought to simply limit them to vb scripting.Unfortunately, I can't find a way to execute vb scripting from within vb, (all the articles are ancient and most links fail - thus I gotta believe there is an easier way).I'm at a deadline where I developed the prototype but trying to use sql statements failed miserably when trying to execute.
View 3 RepliesI am totally new to VB2008, so please bear with this likely dumb question.
I have seen numerous "my first program" tutorial that show you how to create your form, put controls on it, etc. I can get through those just fine.
However, I am wondering: If I compile a set of subroutines into a .exe, how do I indicate which code/sub to execute initially? I am an old school programmer (remember COBOL?), and we always had a starting point; a set of code execute, that initiated execution of other subroutines, functions, etc.
I have dabbled in VBA for Excel, and MS Access, and even those, you indicate in the interface, and menus you create, that first bit of code that brings up the menu, or perhaps the program's main interface.

I'm trying to accomplish something fairly simple in VB that I do everyday in JavaScript.I need to parse text between two strings (HTML tags mainly) that have multiple occurrences.
Sample Data:
<tag>test</tag>
<tag>test2</tag>
<tag>test3</tag>
If I wanted to grab the data in the 2nd <tag> in JavaScript I would simply do this:
var result = string.split('<tag>')[2].split('</tag>')[0];
And the only way I seem to get that to work in VB looks like this...
Dim from = string.IndexOf("<tag>")
Dim [to] = string.IndexOf("</tag>", from)
Dim result = string.Substring(from + "<tag>".Length, [to] - from - "<tag>".Length)
I have some code that access an API out on the web. One of the API's parameters allows me to let them know that I am testing.I would like to only set this parameter in my code when I am testing. Currently, I just comment the code out when I do a release build. Is there an automatic way of doing this based on the build configuration?

I have another procedure called after the loop that does not execute when the loop completes. Please advise as to what I am doing wrong for the code not to execute after the loop in the if/then/else statement or why it is not executing if I remove the if/then/else statement and just placed the called sub after the loop or why the code does not go back to the form load event and then call the next called sub.[code]

Basically that line just figures out the grade no major code work there, what I want to do is execute that specific line with different variables without running the whole application and navigating to the point in the application which for this segment would be completing a 150 question exam, or coding some #temp page and running it from there.

The check box list has an event called "ItemChecked" or something, which triggers when an item is about to change its checked status.
So, it is before the check occurs.I couldn't find an event that occurs after the item has changed.. I want to execute some code only when an item is checked or unchecked.
