Execute Complex Code From String (For Loops And References)?

Apr 22, 2010

This is perhaps something that may or may not be feasable in VB.Net. I would like to give my end-user the flexibility to add segments of code to my program, save it to a text file and then run it whenever they need it. This will ease the burden of upkeep; rather than compiling all my code and releasing that at short intervals, I can just let the user update the portion of code they want without having to re-compile the tool.

[URL]

But that does not seem to include variable reference. So if I wanted to add the following code, it won't run.

Dim myText As String = "For n as integer = 1 to 10000" & _
vbCrLf & "me.label1.text = ""label"" & n" & _
vbCrLf & "Next n"
AxScriptControl1.ExecuteStatement(myText)

It would be great if I could run something like that, where as long as all the variables were defined, it would run like compiled code.

Using The Web Service References Tool 2.0 For Sending And Receiving Complex Data (arrays Of Objects) VBA?

Jul 9, 2009

I used the tool about 3 years ago to create the classes for a webservice client to send or recieve arrays as complex data. Now i have to update these classes, since there are additional informations, that have to be exchanged. When i use the tool now with the new wsdl-files, it does'nt create the classes for complex data (structur, IGCTMObjectFactory), but only one class for simple data. In addition i have to establish a new client, that sends an array of complex data and receives another array of complex data. I tried to build the classes manually combining the client that sends an array with the client, that receives an array, but I failed.

In my spare time i give myself programming stuff to do. Today i want to write a function that goes through a string, if the string contains any numeric value the function must return false, if the string has any special characters it must also return false else return true. For example the following strings would return as follows:

String Return Value

Regex - Tokenizing A Complex String (a Snort Rule) With Regular Expressions (.NET)

May 21, 2011

I need help from the Regex wizards out there. I am trying to write a simple parser that can tokenize the options list of a Snort rule (Snort, the IDS/IPS software). Problem is, I can't seem to find a workable formula that breaks apart the individual rule options based on their terminating semi-colon. The formulas that I have cooked up grab all options between parenthesis into a single capture group.

I am using the excellent RegExr tool at the GSkinner site with some of the below sample rule options from Emerging Threats (I parsed off the rule header -- that's easy to tokenize):

[Code]...

I had to play with a few example regex's that work with quoted strings. Finally realized that I am staring at negative look-behinds that avoid quotes that are escaped. This seems to solve any other escaped character, too, because escaped characters only appear inside unescaped quotes.

Convert Code C# To VB - Function References?

Mar 31, 2009

I have some C# code I'm trying to convert to VB.NET. There are some external dependencies I'm referencing in each project. The C# line is

TWriteFileCommand writeFile = (TWriteFileCommand)CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile);

I don't really understand what the TWriteFileCommand in parathesis after the equal sign is for in that statement. When I try to do it in VB.NET, I keep getting errors because I can't get a reference to the CreateCommand function. The closest I've gotten is this:

Dim MyAppBase As OPSupport.App.AppBase
Dim writeFile As TWriteFileCommand
writeFile = MyAppBase.CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile)

However, I have a green underline after the equal sign @ MyAppBase that flags an error "Variable MyAppBase is used before it has been assigned a value. A null reference exception could result at runtime."What am I missing? Why in the C# code is the instance fine and what do I need to get the equivalent instance in VB.NET?

Loops - Cannot Convert String To Integer

May 7, 2011

I need to work with a loop, from my understanding a loop takes an original number and performs a mathematical operation until it reaches the goal that you set IE: do until >= (variable). I am trying to make my loop add the numbers in my string then decide what to do from that sum. I am trying to make a game of blackjack and if your 2 dealt cards >= 17 then a my message box appears. If they are not >= 17 then it will add my 2 dealt cards which are rand1+rand2 and then add card that gets drawn when I click my hit button and decide then decide if it is >= 17 If hitting causes you to go over 21 a message box will display saying you went over. My error message shows as cannot convert string to integer (10 2 4). I want those numbers to be added together.

Public Class Form1
Dim presentvalue As Integer
Dim randomcard As New Random()
Dim blank As String
Dim rand2 As Integer
[Code] .....

I think I should start my loop here and have it be something like blank + cardrnd but I do not have the correct formula and I was checking to see if it added correctly by using an if statement.
'test for adding the number string
If CDbl(blank) >= 17 Then
MsgBox("Do you want to hit on " & CInt(answer) & "?")
End If
'Do Until blank >= 17
'answer += cardrnd
'Loop
End Sub

Monthly Payment Calculation, For Loops To Do While Loops?

Oct 8, 2011

the purpose of the program is to display the monthly payments on the loan.My homework is to use do while loops instead of for loop.Here is the code for the for loop.

Option Explicit On
Option Strict On

Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.

Repetitive Code That References Components Of Main Form?

Jun 10, 2009

I have a lot of repetitive code that references components of my main form. I wanted to create a separate module (correct terminology?) for all this code to be contained. I cut the offending code and pasted it into my new module, changing each label reference, etc to form1.label.click

Form1 was then underlined and I get this message:Handles clause requires WithEvents variable defined in the containing type or one of its base types.I think I'm headed in the right direction, but what exactly am I looking for? Here is a sampling of the code that I would like to keep in a separate place other than Form1.vb:

VS 2008 - Adding References While Dynamically Compiling Code

Jan 27, 2010

I am using CompilerParameters to dynamically compile code... The problem is when I use:
cp.ReferencedAssemblies.Add(CompilerPath & "est.exe")
to add a reference to test exe ... (where CompilerPath is the full path name)
Compiler Path is not the Compiler Application Path

I get an error when compiling stating that:
vb
"Could not load file or assembly 'test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."
If I put it in the test.dll in the "compiler apps" path and then call ReferencedAssemblies.Add with the full path it works.

When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.

How To Execute Code Dynamically

Aug 4, 2010

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.

Indicate Which Code To Execute Initially?

May 17, 2009

I 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.

.net - Execute Code Before Splash Screen?

May 4, 2012

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)
