I have an application which sits on general users machines. What I want to be able to do is for the users to create a new directory through the application that will create a directory on a server that they do not have access to for secutiry reasons. Then the users can create a file within the new folder through the application, again which they do not have access to. The whole idea is to have an application that manages files that are able to be accessed by many users through the application / backend database, and therefore we do not want the user to be able to manipluate the folder / files by mapping to the location. Then if the user wants to work on the file he requests it through the application which then copies it locally to their machine.
The way that I can see this working is by having a service running on the server that has access to create folders and files in this location. The user can then request the creation of a folder / file through the application which then instructs the service to create the folder / file.
Is there anyway that I can pass arguments directly into the service on the server, or would I have to create an entry in a database on the server that the service is monitoring and then performs the request?2a. If I do have to have the service monitoring the database if I make the service check this every second will this slow the server down and will the server guys at a company be OK with this running this quick?I also need to be able to let the user know through my application that the folder / file has been created successfully, therefore what is the best way to do this? Again get the service to write to the database that the request has been completed? If this is the case then my app will have to poll the database continually to check the database that the request has been completed, this could slow the application down?

View 2 RepliesI will need to convert the following VB Form code to WPF C#:
// VB Me.Invoke(New FooDelegate(AddressOf Foo), New Object() {cmd})
Where Foo is just a method taking a string argument cmd.
I tried all the following in WPF C#, but all giving me exception:
//C#
dispatcher.Invoke(new FooDelegate(Foo()), cmd);
dispatcher.Invoke(new FooDelegate(Foo(cmd)), cmd);
dispatcher.Invoke(new FooDelegate(Foo()), new object() {cmd});
What is the correct formatting?

Is there any issues with this? If I'm kicking off half a dozen threads over and over? ie: I'm not using a system where the parameters will get mixed up/corrupted?
I've looked around, and if this is OK/safe to use, this seems the easiest way to get values/params into a thread.
I have written a program that performs multiple httpwebrequests. It reports in to me by writing to the console. In the past, i have used a backgroundworker for this task, but the code became ugly and bulky. Now, i use threading.thread to start the background process. However, i can't seem to find an explanation on updating the UI from the worker thread.
I've read a lot on delegates, invoke and lambda's, and i just got more confused.
Let's say, in my current program i have this line to be displayed in a textbox on my main form:

View 8 RepliesWhat is the best way to pass objects between threads? I would like to create a new thread that creates a new object : Dim myobject as newobject = new newoject Then in my main thread, I would like to use myobject. Ideally I would like to just assign to a global variable but I don't think that is possible. I think I may have to use some form of delegate function (but I think the child thread would need to complete to use a callback). The new thread will not actually end before I need the object reference in the main thread. How should I go about this?
