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.

I am trying to add some scripting to my VB.NET 2010 Windows Forms Application.I have figured out how to compile and execute VB.NET code stored in an external script file from within my app using Microsoft.VisualBasic.VBCodeProvider.CompileAssemblyFromSource and InvokeMember. I can also pass and return parameters to the code in the script file.In VB6 using the VBScript Host control, I could expose instances of objects in my app to the code in the VBScript.How do I do this in VB.NET?I'd like to expose a form object (the main form for my Windows Forms Application) to my VB.NET script.I don't want to pass the form as a parameter via InvokeMember.[code]

I'm not sure I understand the point of CompilerParameters.ReferencedAssemblies. I thought they could be used in place of using Imports statements.I'm obviously wrong because even if I set CompilerParameters.ReferencedAssemblies.AddRange( {"System.dll", "Microsoft.VisualBasic.dll"}) I still need to use Imports System and Imports Microsoft.VisualBasic in the script for it to work.
Are the Imports used only so that I can use MsgBox() instead of Microsoft.VisualBasic.MsgBox()?What if my script "Imports Something.OrAnother" from an assembly called Something.OrAnother.dll. Do I need to scan the script looking for all of the Imports statements and then add them (plus ".dll") to the CompilerParameters.ReferencedAssemblies before compiling?

I am reinitiating again with these great topis on .Net. Mainly VB.Net. A friend of mine shared source projects, but can not compile. It is composed of a project that creates an .exe file and more than one project that create a DLL that are been used during the program execution. The thing is that project 1 (that creates DLL1) has a reference to DLL2. Normal I would say. But what surprised me is that project 2 (that creates DLL2) has a reference to DLL1.
More complex? Let's say that the program has 6 different projects (that creates 6 DLLs) and each of those has a reference to the others and viceversa? DLL1 has a reference to DLL2, DLL3, DLL4, DLL5 & DLL6. DLL2 has a reference to DLL1, DLL3, DLL4, DLL5 & DLL6. DLL3 has a reference to DLL1,..... and on and on. How to compile successfully these DLLs?

I have an .exe file in C++ (gunmake.exe).And... Check it out:
Dim dirNow As String = Directory.GetCurrentDirectory()
Dim dirFile As String = dirNow & "systemgunmake.exe"
FileCopy(dirFile, "C:GunMake2sharpgunmake.exe")
That's what I'm doing to work with my .exe in VB.net.Is there a way to put my .exe into VB.net code?I say. All in one .exe by VB.net?No need to use the two files. :X

I wanted to provide programming support for an application I made. So I used System.CodeDom compiler and it allows me to execute vb.net code on the fly.The way it works is :
- I call the engine and pass references and code that it needs to run
- The code is able to access public subs
- results are obtained after processing completes.
[code]I want that if the code is being executed by user on seperate threads at the same time then their values should be independant. Right now this is not possible as module has been used and not classes.What I want is -> create object of class RunCode, it runs user code and returns. Thus the age variable in class runcode is not tampered with if at the same time another code is executed. But for that module module1 has to be a class also and how can user call Age sub if its a class. I mean user should be able to call all subs/functions by name and it should work like it was working right now.

I am dynamically creating and adding a ComboBox to a specified column in DGV. I also set a DataSource, DisplayMember and ValueMember for the created ComboBox. Somewhere else in my program, I select a number ( let's say 5 ) and based on that number I want to change the SelectedIndex of the current ComboBoxColumn ( I actually loop through the Columns collection ).I tried something like this in a event handler I created:
vb.net
Private Sub combobox_validated(ByVal sender As Object, ByVal e As System.EventArgs)
Dim combobox As System.Windows.Forms.ComboBox = sender
Dim colIndex As Integer = combobox.Tag
[code]....
You will notice here, that I'm not actually trying to change the .SelectedIndex property, but the Value of the current cell.How do I reference the actual ComboBox?

Over and over i keep getting stuck on the idea of adding references to a project. I was looking about visual studios 2010, i clicked the project menu tab, and then scrolled to add reference. When i would click on it, it would bring up a large list to choose from. So, my issue is as follows. I am told to reference via my compile error message a few items. I thought i found the elements i was looking for and pressed OK. When i would try to run, it would still give me the errors.
What am i doing wrong? Am i not doing something correct?
here is my error code, and i looked it up, but for some reason, as stated above, i must not be referencing correctly?

I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements
this is what the code looks like:
vb.net
Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit
For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1
column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp
[code]....
The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.

I'm following an article (here) and stuck on the following:"Once you have created this class and compiled it, to use it in an ASP.NET Web application, start by adding it to the Web application's References folder."
Ok, so do i now need to compile my vb class file into a .dll and reference it from the BIN folder? If so how do i compile the vb file? I'm running VS 2005 .net 2.0

After reading a couple of tutorials, it seems that basically NET works quite like java. All the IDE's produce an intermediate code that I have to distribute, and which NET compiles at runtime to machine code and then executes it. Leaving aside the question why so when NET works only on Windows platforms, I have some other more practical questions:Is it possible to directly compile to machine code targeted at specific platform like XP 32-bit or Win7 64-bit?

Is one able to compile VB 6 code in Visual Studio.NET ? In other words, is it backwards compatible with older VB code?Since I know there is a difference between managed code (.NET) and unmanaged code, I am wondering if Visual Studio.NET is able to compile unmanaged code as well?

I've been using this article [URL]to add into my code the ability to compile code a user enters into a text box. I was wondering if anyone knows a way that I can pass in a variable that exists in yhe program that I have written. So the idea is in my program I have a variable, let's say a filename, that is used. The user of my program is writing their own program in a text box. When I compile the program they have written I want to be able to pass the filename from my program into theirs.

I did a search for "How do I implement Serial COM Port communications? and found a response by Xiaoyun Li which was last posted on April 10, 2009. Xiaoyun's response included sample code. My intent has been to get a clean compile on the sample code, then test it, then expand the code into a real application. I am down to a single error message, which I can't figure out how to resolve: "Method 'Public Sub DoUpdate()' does not have a signature compatible with delegate 'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'." [code]I marked where the error occurs in the code with *** to the right of the error line.The code is attached to a simple form, Form1 which contains a single text box, TextBox1.It appears to me that the code needs a Delegate statement, but I can't figure out how to code it or where to put it.d.

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?

In one of my forms witch I imported from VB2008 there are all properties saved in the *.resx file. One Property, of the Type System.Windows.Forms.Keys, can contain the Value 'Ctrl+F1' witch compiles fine in VB2008, but not in VB2010. To reproduce, simply add the following to any resx file:
<data name="cmdFenster.ShortcutKeys" type="System.Windows.Forms.Keys, System.Windows.Forms">
<value>Ctrl+F1</value>
</data>
It will compile fine with VB2008, but not with VB2010. Notice: The VB2010 also generates this Code in the resx file

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.

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.

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:
