Here is my code
Dim provider = New Microsoft.VisualBasic.VBCodeProvider()
Dim parser = provider.CreateParser()
parser is always Nothing. I know the Method CreateParser is obsoleted. How to create a VB code parser?
Does microsoft have documentation on how to use VBCodeProvider and codedom or any .net book that provide detail on how to use it. i tried to use it to compile program on the fly but never work. It always gives me an errors such as path to the string or file not found.

View 3 RepliesI am having difficulty dynamically compiling a DLL for use with Silverlight 3.0. My goal is to take some rules provided by my users and compile them into a DLL for custom editing purposes.I created a Silverlight class library project in Visual Studio to get the command line for compiling a Silverlight class library. Based on that and the many examples for compiling VB using the VBCodeProvider, I came up with the following method for comping code in a string to a DLL:
Public Function Compile(ByVal code As String, ByVal assemblyName As String) As CompilerResults
' set the compiler parameters
Dim parameters As CompilerParameters = New CompilerParameters()
parameters.OutputAssembly = assemblyName
[code]....
This does not compile with the following error:vbc : Command line (0,0) : error BC2010: compilation failed : 'Member 'IsNumeric' cannot be found in class 'Microsoft.VisualBasic.Information'. This condition is usually the result of a mismatched 'Microsoft.VisualBasic.dll'.'
I've looked and, in fact, the Silverlight version of the class Microsoft.VisualBasic.Information does not contain member IsNumeric. So I appear to be picking up the correct libraries using the sdkpath option. But I have no idea why I'm trying to call that method in the first place.how to successfully compile source code dynamically into a Silverlight compatible class library?
I'm trying to dynamically compile some VB code in my C# project and I'm running into an issue with the VBCodeProvider. It doesn't seem to be honoring the OptionInfer flag that I'm putting in the providerOptions Dictionary.
My code looks like this:
var providerOptions = new Dictionary<string, string>();
providerOptions.Add("CompilerVersion", "v3.5");
providerOptions.Add("OptionInfer", "True");
var provider = new VBCodeProvider(providerOptions);
I set my CompilerParameters.TreatWarningsAsErrors to True, and I get the following error:
Variable declaration without an 'As'clause; type of Object assumed. However, all is well when I put the "Option Infer On" text at the top of my dynamic source code. Am I using the wrong providerOptions key or value? Is there some other setting somewhere else?
I'm having trouble with CodeDOM and the VBCodeProvider.I want to generate an abstract class with a MustOverride ReadOnly Property.

What does the 128 error code mean ? The version of vbc.exe used is the one in the .NET 2 (SP2) folder. Forcing the compiler to work in a new dedicated temp directory does not help (we update TMP and TEMP env variable on runtime, we checked that each vbc use a dedicated temporary folder based on process id and some static counter)

Why is the VBCodeProvider.Parse method in VS2005 not implemented? Is there an equivalent function?
View 2 RepliesI just realized I used my non-partner account the first time, and I want to make sure I receive priority support. In addition, I found out more about my problem and made a much clearer example.Basically I'm having problems getting a dynamically compiled vb.net "script" to find external references (even though they are being added by fully qualified path). I also tried adding /libpath to my compiler options, and still it cannot find the assemblies.[URL]..

I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu
If menuData.Children IsNot Nothing Then
menuData.Children.AddRange(GetChildren(menuData))
End If
Next
If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:
Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu
menuData.Children.AddRange(GetChildren(menuData))
Next
Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))

I've got my text files read into an array.Which was step 1 .My code so far is:
Note: textSKU is just a text box. No event handler associated.
Private Sub BtnSeacrch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSeacrch.Click
Dim objCA As New System.IO.StreamReader(ofdCA.FileName)
System.IO.StreamReader(ofdWarehouse.FileName)[code]....
The message box is mostly just to test to see if it's finding the line. And the problem is it's returning -136.Which I'm pretty sure can't be a value in the array ( actually very sure, as I tested it just to be sure, and it says it's out of bounds).I know it's in the array, as when I change returnvalueCA to a...7 for example, it outputs the correct line from the .csv file.
Edit: Index was outside the bounds of the array. is what the debugger says, as it's trying to output the value of SKUSheet(-136)

Recently (I have no idea when) App.Path in VB6 started to return a URI rather than an absolute path for the location. Instead of returning something like "C:program filesmyapplication it has begun returning "\sacoc$program filesmyapplication"Has anyone else noticed this?
It breaks a whole crap-load of my code.It seems like MS, in their infinite wisdom, have decided there is some security breach with the way it was returned before - just guessing.
I want to get the row count of my datagridview. I currently use this code below. But the RowCount value is &H7. I have 7 rows displayed in the datagridview. The code below seems to work, but I don't understand what &H7 means. Does it have something to do with Hexadecimals?

I set the culture to Hungarian language, and Chr() seems to be broken.
System.Threading.Thread.CurrentThread.CurrentCulture = "hu-US"
System.Threading.Thread.CurrentThread.CurrentUICulture = "hu-US"
Chr(254)
This returns "ţ" when it should be "þ" However, Asc("ţ") returns 116. This: Asc(Chr(254)) returns 116.Why would Asc() and Chr() be different?I checked and the 'wide' functions do work correctly: ascw(chrw(254)) = 254

I have a WPF application that uses a third-party library to perform a specific task; this library, in one of its methods, executes the statement Assembly.GetEntryAssembly().

One of our technicians asked my to write a small library file in which he would pass a filename and an integer. The library would load the text file and find the integer in the text file referenced by the file name and return a string back to his program. He is working in a third party application that uses VB as its scripting language.So, not wanting to worry about the .net install on some of the older machines that he has his equipment installed on I decided to take a crack at C++ (VS 2010). I am doing applications development in C# and the last time I compiled any C++ code was in VS 6, but I though how hard can it be? Well I am typing here so things have taken a decidedly wrong turn. I started out with the C++ Side.
#include <WTypes.h>
#include <comutil.h>
#include <string.h>the BSTR. Tried SysAlloc, didnt work.
[code]....
If I pass a String to a BSTR as a parameter then pass it back again (like the file name) then the VB side reads in the entire string.
I wrote a vb program that would prompt the user to enter a number and then enter the exponent value they wanted the number raised to. When they clicked button 3 it did the calculation. everything worked perfectly.
Now I need to change the program. I must create a function in a module and then call that function from button3 click event. I have tried several different ways and even though it seems to "work", it keeps returning an incorrect value![code]...
