Generally, people here won't answer such general questions. What you need to do is write some code and then post a snippet explaining what specifically you're stuck on.

Yes. Now choose which question you want to fit that answer to.

So I can choose a question and your answer will be "yes"? Let me think of a good one then.

How would the client know which one to choose? In other words, if you (as developer) don't know what the correct version is, then how should a user, unaware of the code and it's dependencies, make that choice?

It's technically possible, yes Thumbs Up | :thumbsup:

But again, why would you punish the end-user like that?

A client might not necessarily be a user. It could be something that uses IoC or a plugin based system with very tight rules about selection. Alternatively, it could be a clueless randomly selecting DLLs in the hope they'll do something useful.

I am still thinking where would this prompt come at? Immediately after Bios checks? But then how would that 'Select File Dialog' crop up? A variant of chicken-and-the-egg problem!

Becoming database-independant takes more than 'just' changing the connectionstring. In some cases you'll have to use a different Connection object. Once you passed that hurdle, there will be another one where you find that Oracle speaks a different kind of SQL than, for example, MS Access.

I wrote a small example that imports data some time ago, that can be used as a starting point[^]. Good luck Smile | :)

i have .net 3.5 in my client and in other machine i have .net 2.0 without development tools like visual studio or other
i want to debug a large scale windows application developed in C# and .net 2.0 .

i used msvsmon in target machine and i want to attach the process (win service in my project). i can see it in my 'attach to process' window's process list and i attach it . but it does not work.

Make sure you have the .pdb files available for the assembly you're trying to debug. If for some reason it doesn't automatically load the symbols, open the Modules window, right-click your assembly name and select "Load Symbols" and select the pdb file. Make sure the source code you have open, the pdb file, and the assembly versions all match up, otherwise you won't be able to load the symbols or hit any breakpoints.

tnx Dybs
after attaching i see this message on every breakpoint.

The breakpoint will not currently be hit. no symbols have been loaded for this document

does this is for .pdb files ?

Try running the Service under a different account.
