I made a small program which i have sent to all users in my network. Unfortunately i forgot about older versions of framework.
Is there a quick and easy way to add older versions compatibility of framework to my project?
I don't think this is possible but thought I'd just double check...
I have a class library project (i.e building this project results in a DLL being created) and I add a reference to this DLL in several of my other applications. This DLL project targets .NET Framework v2.0.
However, some of these apps that use the DLL target .NET 2.0 (or 3.5) and some target .NET 4.0. But because .NET 4.0 does not include 2.0 and 3.5 in it, its possible for someone to have .NET 4.0 installed but not .NET 2.0, therefore meaning that they won't be able to run my app because of the reference to a DLL that requires .NET 2.0.
So the solutions as far as I can see are: 1. Include .NET 2.0/3.5 as an additional prereq for my .NET 4.0 apps... ewww. 2. Create a copy of this DLL project and make it target .NET 4.0 then in my .NET 4.0 apps add a reference to that rather than the .NET 2.0 version.
So far I've been using the second option, which is working fine but its just very annoying having to remember to copy and paste any changes I make in one version of the DLL project into the other one.
So is there any way I can have a single DLL project but have it build 2 versions of the DLL, one targeting .NET 2.0/3.5 and one targeting .NET 4.0? As I've written this down I've just realised I could always build the solution, copy the DLL out to another folder, then change the target framework and build it again to get the new DLL but that's still not ideal.
Using VS 2010 Ultimate by the way in case that makes any difference to the options I've got available
I have some project that written in .net 3.5 environment. But there still some dependency to .net 2.0 .How I can find this dependence parts of the code that use the old API ? I just want to update all code to 3.5 version.Project written in vb.net.
View 4 RepliesThe software I design is for Win XP and older versions such as Win 98, ME, 2000 etc. I currently use VB6 and Win XP for development and packaging, the problem I encounter is that if I use the deployment wizard in XP, the setup will only work on an XP machine and I need to copy all my source to an older machine and use the wizard again to create another setup file which will only work on the older operating systems. Is there a way to rectify this in VB6? If not, does the new VB account for this and be able to make a setup file for older operating systems as well as XP?

View 1 RepliesI've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
As far as the configuration:
Vista:
.Net Framework 1.1
.Net Framework 1.1 SP1
.Net Framework 1.1 SDK

Compatibility Between the 32-bit and 64-bit Versions software of .net2010

View 1 RepliesI have been again blessed with legacy code made (presumably) with vs 2008. It's a Visual Basic project with a dependency to SQLite. The actual problem is that it is needed to install and run on Windows 7. Now, I have VB 2008 express in which I opened the project and tried to run it. It threw an exception which was most likely due to the fact that SQLite.dll doesn't support Windows 7 (and/or 64 bit environments). The exception was System. BadImageFormatException. (ddl version was 1.0.65.0)
I read somewhere in the internet that in order to run it in Windows 7 you need to have newer version of it. I downloaded it and managed to change the reference to newer one. Now in the SQLite site it says it requires .net version 3.5 or 4.0. I know that I can change the target framework to 3.5 or even 4.0 but do I need to change some of the old references in the project properties? All the references seem to be to 2.0 libraries. Like System 2.0.0.0 and path to X:windowsMicrosoft. NETFrameworkv2.0.50727System.dll. Does this actually mean that the application is using .net 2.0 although it target framework would be 3.5 or 4.0?
And most importantly do I need to convert my application manually or by using some tool to .net 3.5 or 4.0 in order to get it running with new SQLite dll which requires 3.5 or 4.0?
How come software created in an older framework version won't run on a newer framework version? Actually whenever i try to run some old specific software having .net 3.5 framework on my PC they show they needs .net framwork 1.1 . What a bad thing?My newer version of Photoshop ans Ms office open all lower version files.

View 7 RepliesI have compiled a successfull application in VB 2010 using .NET 4.0. Because my workplace only supports .NET 3.5 i compiled the app under that framework, and I get the following error:
Error1Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. Line 123, position 5.C:\\My Project\Resources.resx123
Now under that line I have the following code:
<data name="Presentation1" type="System.Resources.ResXFileRef, System.Windows.Forms">
<value>..\Resources\Presentation1.jpg;System.Drawing.Bitmap, System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a</value></data>
I didn't write this code, i believe that it was automatically created when designing my app. It looks like something might not be supported, but am not sure.
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.
View 7 RepliesI am developing an application using VB.Net which is a simple executable which is to be run from a network drive of our company servers. Most users can access this executable without issue - others however can open the executable but have no connection to our database (even though when running the executable off a local drive such as C:, the database works no problem).
From some posts I have seen this might be a CAS issue - however our IT department suggest the issue might be down to different version of the .NET Framework being to blame. Firstly, is this the issue? Secondly, how can I develop my application to work with different versions of the .NET Framework? Surely this doesn't mean developing many different executables?

View 5 RepliesI believe one or more versions of VB.Net did away with "default instances" for Forms.
1) Was it in the 2003 or 2005 version(s)?
2) With the more recent 2008 and 2010 verions, is it possible to use a template or
change one of the files in the project so that default Form instances are not created?

View 3 RepliesI have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).

To the board: Lately I've been getting Runtime error 3447 ("The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32 for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error") when attempting to open a certain program (not one that I designed, just downloaded and installed). I installed this program in January 2009, but this error began happening only this past July. someone else to information about the files vbajet32.dll and expsrv.dll. One site said that the problem was probably caused by the file expsrv.dll being absent, but I checked my System32 folder, and it's there. As far as I can tell, it has always been there (the computer was made in 2008, and as I said the program had always worked before). Vbajet32.dll is also there. I tried uninstalling and reinstalling the program, but error 3447 still occurs. I also tried uninstalling the program and installing an older version, but 3447 is still there.
I tried replacing expsrv.dll, thinking it might have been corrupt, but that didn't help, and I cannot register that dll anyway. I can't figure this thing out. Both of the files are there, and I didn't change any settings or anything anywhere between last January and this July. By the way, I am on Vista.
confirm 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'm looking around and I "think" I'm reading conflicting statements about MonoDevelop's ability to support a VB.NET project. Some places say it's not possible yet, and other places say that you can with MonoDevelop V2.10... unfortunately I can't seem to find this elusive v2.10.
Do any of you know if this is currently possible (even if I have to install a beta)?
I've been passed a solution that has a vb.Net 2.0 project that references to a .Net 3.5 library. The library compiles with out problem but the vb project does not. It complains of missing objects which are in the library which are correctly added in the imports. Also I see a yellow yield sign next to the reference library also when I add the reference it complains of the framework version difference. Any help is apritiated. Also I'm using VS10. Imported the projects with no errors. A colleague has this working on VS9.

View 4 RepliesI created a small application and an installer project for it. I can install and also run it, only thing htat i dont like is that during setup, it downloads .NET Framework 3.5 SP1 and this takes long sometimes. I want to have it on the installation CD later.
I have seen in the installer's detected dependencies, that there is the 3.5 framework contained and it has a InstallURL property = [URL]..I am a little confused about all the Framework stuff on this site - so just 3 simple questions:
1) which file exactly do i have to download,
2) where to put it and
3) what to write into the property InstallURL then? (Maybe needed to change also other properties)?
I'm facing a major problem with a Deployment Project I created to install one of my applications.I am using the ENGLISH IDE of the Visual Studio 2008 - even though my end users will have German environments. This is why I set the
Localization = German
Property in the Deployment Project's Properties. The UI of the generated setup is German, so all's fine there. However, the setup installs the ENGLISH .Net Framework. I have not found any way around this.The problem are at least twofold:
1. An English Framework on a German PC might cause instabilities.
2. It's a big flaw to see UI inconsistencies (i.e. the UI and Setup of the application is German while the NET Framework shows certain elements in English, e.g. the DisplayName property of cultures)how can I get the project to install the localized .NET Framework?
In vb.net 2008, when I start a new project, it defaults to "Enable Application Framework." I add the following code to a button click handler to the main form in the new project:
Dim k As Integer
Dim s As String
For k = 1 To 5000000
s = Mid(s & k, 1, 30)
Next k
End Sub
Then, when I try to break execution to debug using the pause button, I get the message "No symbols are loaded for any call stack frame. The source code cannot be displayed." If I uncheck the "Enable Application Framework" project option, it breaks and debugs properly. (This also happens with other code not just this example).Is there a way to disable the Application Framework by default in a new project?Is there a setting that will allow a project with Application Framework enabled to break and debug? Did I mangle the installation? This is a recent VS2008 installation. Is there some option I should have selected during installation?
