Upgrading .Net Project From Framework 1.1 To Framework 4.0?
Feb 2, 2011
I 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).
I have upgraded a solution with several projects inside from VS2005 to VS2010, and because of a dependency issue I updated all projects to target .NET Framework 4.0. One of the VB projects now doesn't load two of its forms. I got an error:
[Code].....
Another form loads perfectly. The DependentVBProject builds fine, and is set as a dependency for the startup project.
Before upgrading to .NET Framework 4.0, this project loaded fine, but something else that had it as a dependency did not build (because of other 4.0 dependency).
I am work on VB.net 2003 Framework 1.1 for last 3.5 years in windows Application.We are currently migrating to VB.net 2008 framework 3.5, but i don't know about the features which related to ADO.net and which is important to performance. I know linq to SQL but our architecture is made in .net 2003 so we should follow this.Any features which is very important to enhance the performance?
I've developed an application using VB 2008 Express and there are some customers using it,of course they have framework 3.5 installed.Can I upgrade to VB 2010 but keep target of my project to framework 3.5 (there is a option on Compile tab to chose target framework version),is it a good idea or not ?
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
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.
I want to start my project with a sub main by disabling the application framework. The problem is that if i do this then the application starts and then exits in a few moments. Is there a way which could hold it until the last form is closed.
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.
I have VB.NET Window based project built on .NET 3.5 Framework that is working on the Windows7 32 bit System but when I try to run this same application in Windows7 64 bit System it gives an error message: "System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)"
I 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 work for a small company and we are planning to build our own framework using .net . For example if a dropdown is placed in the form and set the custom property to Users, then the users list from db from has to populate. The developer will drag and drop the custom control and set the connection string in config file. Other things are to be managed by the framework.
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?
I am attempting to publish a project I have just finished on a DVD. The problem I have is a lot of the computers this project will land on, have no internet capability.
How then do I get things loaded on their computers such as "MS .Net Framework 4 Client Profile" and the Powerpack dll?
I am trying to upgrade a project that was originally designed in Vb6. I am trying to bring it forward to Visual Studio 2010 beta. One problem that I am having is that the testbox.locked property is no longer supported. What would be an appropriate property to use in this case?
I have to update and old VB project made with Visual Studio 2005 that uses Crystal Reports to Visual Studio 2010. I've installed the Crystal Reports plugin for VS 2010. I can compile the program under VS 2010 but when I run it and try to generate a report I get many errors popping up from the Crystal Reports Viewer. When I compile and run the project in Visual Studio 2005 (with the old Crystal Reports plugin that comes with it) everything works fine.
The problem is caused by SQL Expressions that are SELECT statements that are not enclosed in parenthesis. This is a problem because there are ~250 SQL Expressions like that in the report file (and it's not the only report with this problem). When I look at the .rpt file in Crystal Reports 10 and use Database -> Show SQL Query the SQL Expressions have parenthesis around them despite there being no parenthesis around these statements in the SQL Expression Editor. When I do the same in Crystal Reports 2008 the SQL Expressions don't have the parenthesis included.
Is there a way to make Crystal Reports 2008 or the plugin in for VS 2010 automatically include the parenthesis around SQL expressions, or was this feature removed? If it was removed, is there anyway to enclose the SQL expressions in parenthesis other than editing each one manually?
if an app created in Visual Basic 2008 can be installed on a machine that has the 2.0 framework installed?Are the frameworks backwardly compatible? I'm basically thinking about a no frills basic type of app with no calls that would make a conflict on the lower framework.
is it possible after compiling the exe to make it a standalone exe that does not need the .net framework to be installed on the clients machine, because some clients have IT policies that forbid them to make installations. most of my applications are Ms access + vb.net so is there a way to give the customer the db with exe & no other installation steps are needed.
Now when I comment these, the application is executed flawlessly, but when included program requires Framework 2.0 SP2 upgrade, I searched MSDN for this but looks like this is available from Framework 1.1
I dont want my users to upgrage to SP2 for such minor things but cant also remove this from my code, Is there an alternate to achieve similar ServicePointManager settings without a Framework Upgrade?
I am on windows vista 32bit.I installed .NET4 and my projects will not open.I had to uninstall and go back to 3.5 w/ SP1.Is .NET4 not yet "complete" and compatible with VisualSutdio 2010 Ultimate?
I know you from microsoft but can you stopto all those old threads that related to flash and browser because you are pushing new threads to the back. If you want to post something that can benefit the forum members, just post in
I want to attach .net framework 2.0 file in wix.how can i?so whenever client want to install the msi then it will install the framework directly.so how can i bind the framework in msi package?
Basically, i am trying to determin if an application made for 1.x will run on a computer with just one copy of the .NET framework installed which is a higher version than what i am targetting, ie: it only has one copy of .NET 2.0, or 3.0, or 3.5 or 4.0 - has one copy of either of these and thats it, the hypothetical computer would not have 1.0 or 1.1 installed.
I create a project with DB Ms access on .NET Framework3.5. and I make it exe. this application doesn't work on XP, so I Downloaded NET Framework3.5 to work.My question is: can I change the .NET Framework from 3.5 to 2.0 after create my project.
