Ok, thank you for your response.

I knew there had to be a way to use Math.Round and get the answer, but i wasn't clever enough to think of your equation. Thanks for the response maybe now I'll be able to finish my homework. Smile | :)

Well....I would suppose you do something like this

int number = 57;
int remainder= number%10;

//If you always are rounding up....51, 52, 53, & 54 become 60 and not 50
//then simply add remainder to your original number.
//If you are wanting to round down in these situations, you need a simple 
//switch(not the literal coding keyword switch...I mean a logical switch...an  
//if statement)
if(remainder< 5)
{
   number += remainder;
}
else
{ 
   number -= remainder;
}

That will probably give you the best results...and if you're doing this for homework, that's probably the way they wanted you to do it in the first place

This is my take, it's easier than the other ones:

int bla = 57;

int rem = (bla % 10);
bla += (rem == 0) ? 0 : 10 - rem;

Help with Getting info on a running process

UTRocketFan3-Oct-06 5:22

I have created a windows service that looks for the existence of a running process and if the process does not exist it will start it. So far this works great, however I have a scenario where sometimes this process will be running multiple times for different customers. When it is kicked off for a customer, their ID is passed as an argument when the process starts up. Is there any way to see what arguments are being used in a running process? I have looked at using remoting, but it seems like overkill to get the info that I need. I also looked at setting the MainWindowTitle so I can look at that, but that doesn't seem to work either. In a nutshell, I want to say is process A running, Yes then for who?

Any help would be appreciated.
Thanks

Sean

Couldn't you just use a Mutex. Have the process create a Mutex with a name that includes its customer Id. If the expected mutex exists, the customers process is running.

This may be simpler than running through all the processes and has the added benefit of preventing duplicate executions of an individual customers application.

The mutex looks like it will work great. Thanks

Maybe you mean Process.Username property? It's available only in .Net 2.0 though.

Question on Visual Studio & Project References

malharone3-Oct-06 5:17

The project I'm currently working on high level has 3 primary projects:

<solution>
|-> Definitions [dll]
|-> ClientConsole [exe]
|-> ServerConsole [exe]

Definitions project has no references. ClientConsole is an exe that will be distributed on clients and references "Definitions" project.

ServerConsole is an exe that will be distributed on server(s). But the requirements allow, server to present itself as a client and thus be an acting "client".

My question:
How do I add "ClientConsole" as a reference to the "ServerConsole" project as the server needs to be able to instantiate the client related objects (UI, other classes). The "Add Reference" fails since "ClientConsole" is of type exe.

I can NOT make "ClientConsole" a class-library and add a new additional EXE project just for launching the ClientConsole.

I have tried all of the following:
1. Keep ClientConsole an exe, and as a "Post build event" on "ClientConsole" project to copy and rename itself as a DLL to the references folder of "ServerConsole" project. This does not work because ...
a) Visual Studio locks the DLLs and thus the new DLL cannot be copied to the destiation folder
b) Even if VS does not lock the file, the intellisense will not reflect the changes in ClientConsole when editing code for ServerConsole when "ClientConsole" is updated

2. Change ClientConsole to a DLL project, and add it as a project reference to ServerConsole. I'll have solved my issue with intellisense and VS picking up the correct DLLs. And as an icing on the cake, set the "post build event" on "ServerConsole" project to rename the "ClientConsole.dll" file to "ClientConsole.exe". This is an ideal solution for me, but this also bomb because ...
a) when the client is compiled as a DLL, the entry poing info "Main()" is not defined so renaming the DLL to an EXE throws error that it's an invalid Win32 app.

I'm sure I'm not the first one to encounter this error. What do you suggest?

Thanks,

Why not?

State the obvious and suggest you move the relevant parts to a new Class Library and have ClientConsole become a bootstrap to the controls and forms in the new class library.

Unfortunately, where I work, it is the "Business" that makes tbe technical decision. They want to have a simplified client-side deployment process. One additional DLL and the hell breaks loose!

They've dictated that clients should have "Definitions.dll" and the "ClientConsole.exe" only. Rest of the 3rd party dependent references are already installed, so the installer only copies 2 files on the client machine.

Colin Angus Mackay wrote:

I was hoping that from the post build event of "ServerConsole", somehow I could recompile the ClientConsole as a WinExe application.

Bindingsource C# Adding New Event

JensB3-Oct-06 4:14

Hi,

We are using data-binding & typed datasets in our C# .NET 2.0 application (VS2005). We have a bindingsource which has as datasource a dataset and as datamember a datatable.
In the form we have a grid which is binded to that bindingsource. We allow new records to be created on the grid.
When the users navigates to a new row, the "Adding New" event is raised. We would like to handle this event because we need to set the key of the record to a new Guid.
We get as parameter of the "Adding New" function "AddingNewEventArgs e".
Then e.NewObject should be set. Well, this doesn't work. After setting the e.NewObject the program crashes.
It's like it does not accept my Typed DataRow. Maybe the collection underneath in the Bindingsource accepts another type?

Any ideas?

Best regards,
Jens

I did that in several data-bound DataGridViews with no problems. You don't set the e.NewObject to something. Here is how I did it.

private void MyDataGridView_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
    MyDataGridView.Rows[e.RowIndex].Cells[0].Value = Guid.NewGuid().ToString(); 
}

Do you mean the priority of the application? Where increasing the priority of the application will increase the speed of the application but if set to high it will degrade the performance of the rest of the system?

mejojo-
Thank you for your response. I forgot to specify we have not upgraded to the 2.0 framework. We are on 1.1 System.IO.SearchOption opt = System.IO.SearchOption.AllDirectories; does not seem to work.
My first attempt(b4 the post) was
DirectoryInfo di = new DirectoryInfo(@"C:\Temp");

foreach(DirectoryInfo file in di.GetDirectories())

{
Response.Write("File Info \""+file.FullName+"\""+"
");
}
But this does not go into subdirectiories. Can some one help?

What is the best option for displaying the result set to the web, DataGrid? Instead of Console.WriteLine what would I use for the web? From what I was told I a console app is done the same way from a Web App (ASP.NET) but Console.WriteLine does not display my result set.

Thanks in advance.

I was postulating here in the forum for sometimes that if you want some functionality of a certain library of .Net framework, you can install it on your machine and explicitly reference to that library. So you'd be using .Net 1.1 for everything else, yet enjoy this new feature of .Net 2.0 or even 3.0.

iamnew2C# wrote:

Sure it won't. You have to put this code in a recursive function and recall it each time.

You are enumerating Directories. I guess a TreeView would do the job.
