I want to update the project with some new functionality but I want to keep the original intact.What's the best way to go about creating a new project with copies of all the files and resources from the original, but with paths that all point to the new copy?

A colleague has written a useful tool. He wrote it as a standalone tool, but it works even better as an includable dll, though it needs a bit of other functionality for it to be a really good drop-in component. What I am wondering is whether a project can be compiled as both an exe and as a dll?
There are alternatives, such as having a dll version and an exe version, since the dll version needs to include a few different methods that the exe version doesn't need, but this alternative sucks, since it would mean changing two sets of code.
Another alternative is to build the dll, then change the exe to be a project that references the dll....and does nothing other than calling one method in the dll. That kind of sucks, too, but not as bad.
I want to be able to use his module in some of my programs, and it really should be built as a component rather than a standalone app, but I want to know whether there are other options that I haven't considered.
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 thought would be a simple google search but apparently I am not searching correctly - or something...
Does anyone know if I can do this? I would like to start working with 3.5 however all the projects I am doing are still in 2.0
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 have an application that uses a Microsoft DLL (Microsoft.ComponentStudio.ComponentPlatformImplementation.dll) which is used for OS deployment and accessing the catalog files. Version 6.0.0.0 is specific to the Windows Server 2008 catalog files. The newer version 6.1.0.0 is specific to Windows Server 2008 R2 catalog files. Attempting to access a catalog file with the incorrect version results in an exception.
My application (VB.NET using VS2005) needs to be able to access either version of these catalogs - I'd be happy with two executables (one for each catalog version) but obviously I don't want to maintain two sets of source code for each. Specifying both sets of DLLs in the project reference is not possible as the DLL names are identical. I'd rather not have to manually add and remove the DLL references each time I want to a build. As far as I know the interfaces etc are effectively identical between the two.
I 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?
I was recently looking at some of the other .Vb files in VB.Net 2008 Express Edition.
By the way, just so you know I could install a full version of Visual Studio if need be from;
2203, 2005, 2008 or 2010
I am using using Visual Basic Express edition 2008. How can save / save as my project in different version when I make changes to the code? i.e. save the same project whenever I make a change in the code and keep the previous version of the code for future reference?
View 3 RepliesASP.NET pros out there can answer this question. I have a single web application that contains a website and a web service - both have several assembly references in common (data access layer, utilities, etc) - however, recent changes made to the web service will require different versions of the common assemblies, versions that the website won't work with (in case you're wondering, the website is some legacy 1.x .NET code that explodes when using the newer version assemblies.)
allow my web service to reference one version and have my website reference another? I can obviously have only one version with the same name within the bin folder.(P.S. - It just dawned on me that I could probably compile and reference the common assemblies with a different name, and place those in the web app's bin folder - but that sounds really fugly...)
I am a vb6 enthusiast willing to try NET. I am confused by all the versions and the fact that limitations of the 'free' version are not spelt out. My requirement is to be able to convert vb6 applications (possibly, but don't mind a manual rewrite), to write applications (not for tablets or phones yet) that I can use myself and possibly publish to others. I would like to allow printed reports for my financial applications. I will have a small home network up soon but ability to operate on a network is not critical. I do NOT want to download a 'free' version and find that it is crippled one way or another, like allowing development but not publication.
Whether the 'free download' is OK, and which one (Express?), or point to a site where the versions are clearly laid out.
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.
What is the best way to make a program that works with multiple versions of Microsoft office? I own office 2007, so my program uses the office 2007 com objects. When I try to use my application with office 2003, I get errors related to the com objects. Does Microsoft have com objects that are compatible with multiple versions of office?
View 2 RepliesFirst of all, I wasn't sure whether this was VB.NET or General Developer content... It's not technically about VB.NET code, but it's not very general either since it is specifically about Visual Studio. Feel free to move it if required.A while back I realized that all of my database connection code was getting very biolerplate. had 'developed' my own method of connecting to an Access database and storing the results. Basically, for each table I create one 'Manager' class and one 'Entity' class. The Entity class represents a single record in the database and has properties for each field.

View 8 RepliesMy project will be a collection of 3 projects that have similar GUI's and call on common assemblies. I want my project to contain 3 executable files when published that will load one of the designated smaller projects. Each of the smaller projects is designed to perform a different task, yet they are all similar in terms of looks and how the user interacts with the program. The best way to picture it would be MS Office. All the office programs (excel, word etc..) are part of the same package, and look similar but they perform different tasks. You can load any of these programs by opening the relevant .exe file, which is exactly what i want to do with my application.
