Hi:
I am programming in C# and wondering if there is a simple way to have direct communications between 2 programs on the same PC.
Here's the scenario I am thinking of:
1. Program a and program b are installed in a machine
2. progA is launched
3. progA needs some information and launches progB if needed. If progB is already launched, progA does not relaunch progB, but uses the active instance of it.
4. progB provides the information to progA.
5. progB is available for any other program progC etc. that want to call it for information
6. progB terminates only when the machine is rebooted.
I hope my weak terminology is still comprehensible. Please could you give me tips on how to launch progB from other programs and how to leave it on (not be a child of the lauuncher), and how to initate communication with progB if an instance is already running.
Regards, smurfy

This seems to be a typical multi-process application. I prefer to implement them as server/client.
1) Build Program B as a service on Windows. Program A(or C) can easily check if the service is running. Launch the service if it's not running.
2) Implement an IPC channel between Program B and Program A(or C).

Launch Program B as a service or spawn it as a separate process. Either way, Program B will be on even when you close Program A.

Through IPC, like socket or shared memory.

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.

i am not using command line i am using the compiler class

Sorry, I would have replied sooner but I was waiting for you to ask the question again in another post. 
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

Hi guys! Help please I am a newbie in C#, I have been working on an application and was working fine on MS Visual C# .Net and then yesterday I downloaded and started converted the application to MS Visual C# 2005.

I Posted a lot of times asking for this, and searched in many ways and I could finally find this article!!
With this you can read a ListView and a Treeview from another process.

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

There's nothing wrong with that! That's what these forums are for, after all. 
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.

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.

Exceptions are debug-time notices to the users of your code

Hi,
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

 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.
