Is there any way to make my programs use a lower version of net.framework other than the newest version 4 that comes with VS2010?I use my programs within a closed network and there isn't an easy way for me to install any software since I'm not the administrator.
View 3 RepliesI can create a brand new empty console app in Visual Studio 2008 and add a reference to c:myfilesCrystalDecisions.Enterprise.Framework.dll and verything works just fine.If I do the same thing with the same file in Visual Studio 2010 (after changing my targeted framework to 3.5), I get the error that "CrystalDecisions.Enterprise.Framework.dll or one of its dependencies, requires a later version of the .NET Framework than the one specified in the project." In Visual Studio 2010 it won't work unless I change my targeted framework to 4.0. How is it possible that a DLL could be incompatible with version 3.5 of the framework in VS2010, but compatible in VS 2008?

It appears that the executable application I created can only be run on a computer with .net 4. How can I compile/create the executable to run on a computer with .net 2?
View 3 RepliesI just updated to VS2010 SP1, but I cannot be certain this problem didn't exist prior to the update.When I build my project the version in /bin/debug builds, but nothing builds in /bin/release. I do not remember making any changes that would affect this, but nothing I do now will get the release version to build.
In the Application settings under "Compile" I have Configuration set to Release and the Build output path is "binRelease For Debug I also have Configuration set to Release.
There doesn't seem to be anything else left to change/adjust - but no matter what I seem to do nothing builds in the bin/release folder.
I would like to build a text string that is the build version of my program. In VB6 I would use the values retrieved from App.Version.Major/Minor. I have looked for something similar in VS2010 VB but unable to find it. I did find information on the .NET framework, but I am looking for a build version of my program.

View 4 RepliesI am writing my first application in VB 2008 Express with .NET Framework versions 2.0, 3.0 and 3.5 installed. When completed, I assume the application will need to check whether it is running under .NET Framework version 3.5 or later. I have not found any properties that I could get which would give me this information about the environment in which the application is running. Is this something that the non-user code in which my application is wrapped by the IDE checks, or is it something that I have to check myself within the application ? If the latter, how would I do that ?

Is there a way to check if the necessary version of .NET framework has installed and if it has not installed to display a custom message explaining the user what is the problem and how to download the required version of .NET framework in order to make the application work?

View 8 RepliesI need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).
I'm writing a code that will check if .net framework 3.5 SP1 is installed before installing the program.The command I found googling around was System.Runtime.InteropServices.Runtime Environment.GetSystemVersion..I wasn't able to verify the correct .net framework version using this command.I'm currently running 3.5 SP1 and this command is showing v2.0.Is there another way to get the correct .net framework version?
View 2 RepliesIs it possible to reduce the version of .net framework of my application. For example: Host using my application have .NET 2.0 I make changes in my app so that it always run as .NET 2.0 not the latest .NET 3.5
Or another idea i have is to deploy .NET 3.5 in installation package i.e. if he runs my app and it detects .NET version and if its not .NET 3.5 then .NET 3.5 installer should open else my app should run.
I'm trying to add functionality to my application that will disable buttons and checkboxes depending on what version the OS is when the app is launched. I made a test app to test this but unfortunately I can not get it to work. Here is my code:

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?
View 23 RepliesI have an application that will not load unless my local SQL Server is running on an Vista Home Premium machine. This started after a .Net 1 to .Net 4 conversion. I am using a sub main sub that is not being called (msgbox is not fired when entering the app), however, I see the app through taskmgr with increasing memory usage, but then the app is removed from the list. By design, if the program cannot locate a SQL Server a form pops up with a connection box to locate the SQL Server for the app. How it determines if it has a valid connection is the program looks for a connection string in the registry, then attempts to connect to it, however, none of this code executes because of the failure to enter into the sub main.The two machines I have tried the 32 bit app on
XP Pro: Failed / Using SQL Server 2008 Express
Windows 2003 Server: Works / Using SQL Server 2008 Developer
Both machines have .Net 4 Client Profile with Extended?
Mainly I ask this because I don't want to distribute both versions, and if I need to instal a 64bit .NET on an x64 PC and a 32bit .NET on a 32 bit PC then I would need to make this check in my loader application to download the correct version for the correct PC.

I wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?

View 2 Repliesconfirm the forum for this question about Visual Web Developer 2010 Express. I found a VWD Express forum, but it was in Spanish... Lo Siento. My issue is selecting a down-level, 3.5, framework version as I create a new project/website. I have figured out how to CHANGE the target framework version once the website/project is created. I have the 3.5x installed on the system and available. The articles I have seen discussing this issue, refer to a framework version selection drop list in the new project creation dialog/wizard. I do not have that option.

I have a VS2010 solution (upgraded) that has two projects, an EXE and a DLL. In both the Target framework versions are 4.0. When one look at the references of the EXE project, one can see that the System.dll (and System.Core.dll and so for) references to the v4 version (the latest); however, in the DLL project the references points to the .Net Framework v2 version. Why is this happening? How can I make all my projects to point to the v4 libraries?
