VS 2010 Forcing VB To Use A Specific .net Framework?
Feb 10, 2010
I used to write code at a previous job in lots of languages, VB just one of them. At my new job I am tasked with writing code again. I have picked up VB 2010 express to get started and will move forward from there. The problem that I am facing is that 2010 uses the .net 4.0 framework. This is too new for the add-ins to support.
It follows, my question: Is there a way that VB .net 2010 can be forced to use a specific .net framework? Can I tell it to use the .net 2.0 for instance?

Ok a simple question, I should know the answer but I am embarrased to ask. How do I get the .Net 4.0 framework deployed with my application when I publish it.Instead of having to download it on other pc's. Im sure its just a tick box in the preferences/settings somewhere.

I was messing with my program as I was having trouble getting it installed on machines without VB Express installed already. I adjusted the .Net requirement to 3.5 as I figured more people would meet that requirement without additional installs and now I get this error on my program when trying to change settings.Any idea how to get this set back up correctly.I'm on a Windows 7-64bit machine, using VB Basic 2010 Express.[code]

I'm creating an updater for an IP address, and I need to ensure that only one instance is running on the computer. This is to prevent (or at least make it more difficult for) having multiple tunnels running (it's an updater for an IPv6 tunnel).I've seen various ways of doing it in VB 6.0 and early .NET, but nothing that deals with .NET 3.5 or VIsual Basic 2010.

I have a question to ask you. All of the programs that I made always worked perfectly in my PC. But, whenever I test it on another PC, it requires a thing like... Microsoft .NET Framework Version 4. Which is really annoying, cuz that thing installs in 15 minutes. I mean, can I do something about this? Is this common?

My application seems to require .net framework 4 to run. Hence not working on standard XP installations until .net 4 is installed. How do I make it so that it only needs 3.5, or whatever XP uses natively?

I have made an application with VS2010, meaning it requires .NET framework 4 to run properly.If the program is ran on a machine with .NET framework 3.5, it returns an error stating I should install 4.

I started a project in VB 2008 and the target Framework was obviously not 4, like it forces in VB 2010. The issue is the computers this application is being deployed to have 3.5 as the latest .NET Framework.

I am having a few dramas with running my completed project on another computer. I created my project using Visual Studio 2010 (Microsoft Visual Basic 2010 Express).The error messages I get say that the program is unable to access the .NET framework. This is because the .NET framework is not loaded onto the other computer and loading it is not an option.I've done some searching on the internet and I found instructions for going from a dynamic library to a static library and building, rather than publishing the finished product for C++ 2010. So, I assume that I need to do something similar but I haven't been able to apply this to VB 2010 Express.The finished product needs to be self-contained, so that the .exe file has all the libraries and compilation instructions it needs.So, is someone able to tell me how to link up the files I need and re-package my project so that it works on any computer that runs Windows.

I understand that I need to run ... corflags.exe /32BIT myapp.exe against my VB .Net app if I want to make sure it's associated 32 bit dll's will be forced to run as 32 bit on 64bit computers.
If this will work this looks like a good idea to me since I don't have the opportunity to recompile them on a newer Visual Studio that supports targeting 32bit. But I have a couple of questions...
Question 1:Is there an easier way to get the corflags.exe program without having to download the whole .Net Frameword 2.0 SDK?
I guess this is what I need to download if there is no easy way to get the corflags.exe file...
Download 1:Microsoft .NET Framework Version 2.0 Redistributable Package (x86)

I'm running Visual Studio 2010 with the Dot Net 4.0 Framework. I've been running around everywhere looking for the answer and haven't found anything. All I want to do is be able to access the Tags and Comments of an image file through my code. I've tried a bunch of different things but to no avail.
Dim dra As IO.FileInfo
My.Settings.Properties.ToString()'didn't work
dra.Attributes.ToString()'didn't work
IO.File.GetAttributes(fullPathFile)'didn't work
[code].....
And a bunch of others that I don't feel like undoing to.

I've been working on a new application and realised that I want the target framework to be 3.5 (4.0 isn't rolled out yet). So, I changed it and now when I try and debug I get the following error:
"An error occurred creating the form. See Exception.InnerException for details. The error is: Unable to cast object of type 'System.Windows.Forms.SplitContainer' to type 'System.ComponentModel.ISupportInitialize'."
I really don't want to have to delete and recreate the splitContainer....

I'm struggling a bit with Entity Framework 4.x. Let's say I have a model called Product. It was generated from a database table. There is a field in this entity called CreatedDate. The MySQL database has a default value for the current timestamp. I don't want Entity Framework to set this field when inserting or update the table. Problem is, I can't seem to figure out how to tell EF to exclude this field from being sent back to the database, but still retain it as a field to be viewable in the application.

I have built a Dll and a Windows Service in vs2010. Both are targeting the .net 3.5 framework, but when I install it on the server it installs fine, but for some reason it targets the 2.0 framework and any time the methods fire that are using linq it crashes out with a clr20r3 error system.nullreferenceexception. Not really sure why it's not targeting .net 3.5.

I just read this post url...Post #2 by jmc states indicates the use of Entity Framework instead of typed datasets.when jmc says something I usually pay attention. I have a large app that I've been converting from VB6 to .Net and I've used mainly typed datasets.It's a single user app that uses an Access database. I'm have no problems retrieving the data from a table or multiple tables and I'm very happy with its preformance.Is it worth scapping what I've done and learn how to use Entity Framework? I should add that I'm near the end of my programming career not the beginning.

I am using VB.Net 2008 Express on Windows XP, and am trying to use WM_LBUTTONDOWN in one of my programmes.
CODE:
This appears to work correctly, in that it goes to the Exit button and I can see the effect of WM_LBUTTONDOWN and WM_LBUTTONUP, but the programme does not actually exit; it just sits there with the Exit button highlighted. I added all the TimeDelay() subs to see whether it needed the extra time.
I also made the following changes, and again, it goes to the Exit button and I know that it is on the button using Spy++, but the programme does not actually exit
CODE:
How do I force it to exit?

Is there a way to force a form to be active and shown?
From another form i am doing:
Me.Hide
Form2.Show
When this code is run, the Form2 is minimized.
I've also tried:
Me.WindowState = FormWindowState.Normal
in the load event, and it still loaded it in minimized mode.
