Programmatically Compiling Code From Within A VB Project
May 7, 2009
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 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.
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:
I am using 8 different vb projects in one solution, beside this I am also using one 3rd party control ion all the projects, while compiling the application it takes around 5 minutes to build the project, While building the application I have observe that it uses lc.exe file which is used for "Reads text files that contain licensing information and produces a .licenses file that can be embedded in a common language run time executable." at this point it takes too much time.
when i compile the project and run it get the error Project Project has encountered a problem and needs to close. If you were in the middle of somthing, the information you were working on might be lost[ Close ]
How do i compile my vb project?I tried to compile , but i'm not sure which setting i should put and what i shouldnt.i did tried publishing, but i'm not sure which path of location to be publish and i put c:/ as the path and i can't load the database.The location of my db path in the string.[code]
My app bundles a set of VBScripts (UTF8 text files) into a VB.NET assembly. I used to embed the script code into the classes as String members, but this is proving to be a poor design. I want to include them as resources instead. What's the best way to add resources to the CompilerParams?
What I've got so far (excluding all the error checks):
Dim comParams As New CompilerParameters() comParams.OutputAssembly = DLL_Path comParams.ReferencedAssemblies.Add("System.dll")
[Code]....
The CompilerParameters contain fields for EmbeddedResources and LinkedResources, but from the examples I found so far these seem to pertain only to framework resources???
I have a problem with one of my projects that has only just started occuring this morning.I am using VS 2010.I get errors on every form that has a VS generated dataset, similar to;
me.<dataset> = new <namespace>.<dataset>() and with events <dataset> as <namespace>.<tableadapters>.<tableadapter>
I just tried to convert some of my Projects from VB2008 to VB2010 RC, but got compiling Errors while compiling the resX Files. Seems like the reason are ImageLists/Icons, since if I remove them the files compile fine. I already tried to edit the Forms witch are showing the Errors with the Designer. The Designer changed the Content of the resX file lightly, but the error was still present Here the Error(German Version): 'FormsfrmUserTmpBUTable.resx : error RG0000: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.' I recall a similar error in the Beta, but since I can't find it anymore, I guessed it was fixed.
I have a simple Win App VB project with a single form in it. I also have an Active X component which I am adding onto this form. This component is made in C++. On building the VB project i get the message "COM Reference 'CPPLib' is the interop assembly for ActiveX control 'AxCPPLib' but was marked to be linked by the compiler with the /link flag. This COM reference will be treated as a reference and will not be linked." but it compiles successfully. When i try rebuilding it or opening the view designer of the form VS2010 crashes. The project is locally creating two dlls namely "Interop.CPPLib.dll" & "AxInterop.CPPLib.dll". I have made the Embed interop types False for both these references.
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 always make back ups of my projects in case I'll really really mess up on the way and want to go back to more stable version. I've tried running one of my back ups few days ago and ended up with importing pfx key canceled. What exactly is pfx key? And what do I do to have my code compiled?
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 have written a c program for calculating some financial task It accepts the input file name or path name from the user processes it and displays the output in 6 output files. i want to execute the same c -source code using visual basic .net.I want to know how to compile the c source code and execute it .
I would like to know how I could generate code from a text file in a particular format into a VB.net or C# source file.I would like my code generating program to read text file having the following format:[code]The idea is to compile the main code after the user have modified the txt file and used the code generating program. I would prefer to write the code generating program in C, python or C#.
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 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 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'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 compiling a VB Project in VS2005 with SP1. This is the error that I am getting when I build this project.
12>C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Microsoft.Common.targets(802,9): error MSB3108: Error executing the ResolveNonMSBuildProjectOutput task. An error occurred while parsing EntityName. Line 1, position 115.Microsoft.Common.targets is a file present in WINDOWS folder and used internally by VS2005 while building the projects. I am not able to get any clue why this error has come.
I'm currently working on building a program that will take a MS Access database system produced by my company and create a VB.Net project with all the forms in it (obviously the code should be manually done, but to save time the forms and controls can be produced automatically).I have tried Googling and seem not to be able to find anything about this (which probably means I wasn't searching with the right keywords), I was wondering whether anyone knows any good resources on how to create the VB.Net project programmatically as I already know how to do all the access stuff.

I have a form-based application that is still in the testing phase. As a convenience while the project is in test phase, I would like to be able to open its VB project by clicking a button on the form, instead of navigating to the directory and open the project by double-clicking its icon. (I'm lazy ) I've added a button to the form. What code should I use to open the project?
I would like to be able to change a single property for every form by code instead of doing it manually. I'm a little new to .NET development, and I thought I was on the right track with the System.Reflection class, but I still can't put all the pieces together. Here is a basic outline of what I'm thinking (pseudocode):
I'm getting a ton of errors like this when attempting to build an empty VB.NET project: 'GenerateCodeAttribute' is ambiguous in the namespace 'System.CodeDom.Compiler' Is this some problem with my .NET installation?
I have a custom control that does some work for me on async postbacks. Normally, I'd call the control directly from the presentation side using the following code on the ASPX page:
<mytag:CustomControl runat="server"> html (or other text) goes here </mytag:CustomControl>
In entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ).What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3.
To be more specific ,from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do? To give the ability to create dynamic table fields those steps will not be sufficient. In all 3 steps database , table and table columns are fixed. There is no way that a user can create new tables or columns dynamically. http:[url].... in this post , it shows how to create manual db, tables and etc using SQL but it is based on ADO.NET but I want Entity Manager to do that.
