I am trying to make a program that can search a directory on the local computer for a certain file and then replace all of the occurrences of that file in the directory and the subdirectories. How can I do this?

Look at the MSDN documentation on the DirectoryInfo[^] class. There's a link to the class's member functions and properties at the bottom. There's also a File class in System.IO you might want.

Thanks, I got that working.
Now I have another question, Can you reference files in the projects references? Like type in a path and it opens a file in the resources.
|
|
|
|
|
To my knowledge, the "Project References" section is only for other assemblies referenced by your project (i.e. another class library). I'm not too familiar with how to use other resources in a project at the moment.

in first go i would say no
if you put more details of your requirement then we may think an alternative

I have a C# web service that is creates a file in c:\inetpub\mdws\dwnld. If the web service needs to recreate or delete the file I get the following;
Server was unable to process request. ---> Access to the path 'C:\Inetpub\mdws\dwnld\catwoman.bbd' is denied.
I was receiving this error when doing File.Copy. I was able to create the file by using a FileStream/BinaryWriter. If I try to create the file again I get this error. I'm using FileStream(path, FileMode.Create, FileAccess.Write). I get the same result if I try to do a File.Delete(path) if the file exists before trying to create.

Maybe the file is being used by another process, have tried to delete it manually?
|
|
|
|
|
Make sure all reader and writer classes which use the file are closed or not. It will never allow to delete the file until and unless those reader or writers are closed.
Either you love IT or leave IT...

I've been working on MatLab,but turns out Im required to write using VB or C++.The huge matrices are kind of a challenge for me.Any suggestions?

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 
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 was visualizing Windows asking an end-user what version of HAL.dll to use

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!

Such a system is guaranteed to be a catastrophic failure.

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
