is it possible to divide a large csharp project into smaller parts (at runtime)that can be compiled independently..........if possible then how to make parts and how to link those compiled parts to generate an exe of the project

I'm not positive, but I think afte the 1st compile, only the changed parts are recompiled on build unless you specifically request a complete rebuild.

How to: Build a Multifile Assembly[^]

In short you use the commandline tool csc.exe to create multiple modules from your code files, then link them together with al.exe

Sorry, I would have replied sooner but I was waiting for you to ask the question again in another post. Poke tongue | ;-P

Unless you are writing a compiler, ie. re-inventing the wheel, then use what is available. You can invoke the csc.exe program from within your code.

i am going to implement distributed compilation of csharp project and i cant manage to divide huge project into smaller compileable parts..........i need some help on it...........i have posted it again in detail which is

i have made a program that works as follows
1->i browse some csharp project and open the main .cs file
2->the program compiles that project and reports errors as we compile in .net compiler
i want to make my program work in this order
1)select a project of csharp
2)the program should divide the project into independently compileable parts
3)then it should display a list of those parts
4)on selecting one part it should compile that part
5)then after compiling all parts on selecting one by one it should link all the seperately compiled parts to generate exe and show the output

With this you can read a ListView and a Treeview from another process.

Catching Exceptions

Unusually for me I'm asking a question...

What is your policy on catching exceptions and why?

What I mean is do you catch exceptions as soon as you can, or do you let them unwind their way up the stack before catching them? What criteria do you use for deciding when to catch an exception?

I like the enterprise library model. You decide whether to catch the exception or rethrow based on configuration.

I will catch exceptions if there is something I can or should do in response to that exception. Sometimes I'll just catch an exception, log the exception details somewhere, and then throw it back up the call stack so that other call sites can do what they need to do with it.

Enjoy the weekend,

Most simple exceptions like validating input and the like I do on the spot. Most complicated situation what I run into in libraries, I'll usually let bubble to the using application, so they can be logged. Those types of exceptions I like to have a full stack trace for tracking the application break.

I guess for me, it all depends on whether or not it's an exception I'll want to investigate and need all the information I can get. Most exceptions in an API library I let bubble.

True - It is just unusual for me to be initiating a thread in this forum.

Weird - It looks like the forum messed up - This was a reply to Josh's post.

Yup, I agree with that - Users not being the most loquacious when it comes to describing the details of what went wrong it can be very useful.

Thanks for your response.

Yeah me too, I usually find what I'm looking for in articles or google. Most of what I can't find there, I assume nobody has attempted. And I assumed that was a response to Josh.

But it's lots of fun surfing for questions I can answer, helps stroke my ego. Poke tongue | ;-P

You should catch them as soon as you can deal with them but no sooner.

So I Wouldn't write:

<br />
catch(Exception e){}<br />
or <br />
catch(OrSomeFileNotFoundException e){} //Unless you can deal with it, don't catch it.<br />

Makes sense to me.

i have a folder view which list all my folders in a tree view form. My requirement is, after selecting a folder if i send a delete command it has to delete all folders and its contents. Problem is only after deleting the files in the subfolders,i can delete the folder. i need to do an recursive search. Urgent.... plzzzzzzzz reply. I am using c# windows application.
e.g
1
11
12
121
122

hi i did but then its not working properly..... if i select a node. the rootnode.nodes property is not taking the subfolders of the child node....

1
11
12
13
131
132
14

in the above the 131 and 132 nodes are not accecible.... they r not coming under the collectios..... plzzzzzzzz help me..

thanks a lot in advance......cheers.

If you use the method above, and pass it node '13', it will process '131' and '132' before doing 13. You're not using the treeView.Nodes are you?

What ever owns the 1, 11, 12, 13 & 14 nodes (treeView or another node) won't have 131 and 132 in it's Nodes collection, node 13 will. A TreeNode object has a Nodes colleciton just as TreeView does. That's why the method above accepts a TreeNode, and pocesses it's children before itself.

Maybe I don't fully understand you question.

Hello,

I am using standard OpenFileDialog window. Is there a way to suppress (disable) the New Folder button, so that the user does not have the ability to create new folders?

Thank you.

I don't see a 'New Folder' button in the OpenFileDialog, so i can't help you there. But if you are using the FolderBrowserDialog, set the ShowNewFolderButton property to false.
