I have a multiline (> 50 lines) textbox containing plain text. I want to add either a session variable to the text in this box. In asp I would have done it by putting in <% %> code blocks but in .net I am getting the following error: "Code blocks are not supported in this context". I assume therefore that this would need doing in code behind.Is there a quicker way than putting all the text from the textbox in a string in code-behind and then adding the variable on like this? I would like to keep the text in my aspx page if possible.

USERNAME ICOUNT IAVERAGE DATE_LOGGED

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)
