Hi, i have a C# project of a program. In the project i have added the windows calculator as an executable. I need to open it when a button is pressed. How can i run an *.exe from within the program?
|
|
|
|
|
Process.Start("calc.exe"); I believe (procoess.Start is definately right )

But with Process.Start() the file must be on the file system. Can i make it run without creating it - for example from a stream or from an embedded resource or from bytes???

Why, is windows calculator not on your file system ?

Use Process.Start[^], passing in the path to your executable.

Hi Everybody,
I want to perform the following actions, can any one help in this regard:
When a user is logged in to a operating system under the Active Directory, the user who have logged in and the current system name has to be saved in a table automatically by a windows service which is running in the server and connected to the Active Directory.
For this I want to get either the computers and the user who logged in / the users and the computer in which they are working in.
Thanks in advance.
Best Regards,
M. J. Jaya Chitra

WindowsIdentity currentIdentity = WindowsIdentity.GetCurrent();
Then look at the Name property on the currentIdentity object.
Is this what you mean?

hi
I want to know whether the node which i am adding dynamically to a treeview is present already or not .
I dont want to use database for it .
Thank you

You will need to write a recursive method which iterates through all nodes of your treeview and checks if the node you are adding is present or not.
|
|
|
|
|
thank you i have written a recursive method and it is working but slow ...
i was looking for a simple method..
*** Why EXPERTS behave like a fool ***

What do you mean by simple? I don't think there is any other way rather then using a recursive function, you can just try to optimize it.
You could also maintain a HashTable or Dictionary variable where you will store all nodes that you add and check whether the node you are adding is already present but in that case your application will need more memory. If performance is your priority you can do it but if your priority is memory usage then you should go with recursive function. It depends on the situation.

quite simple...use
treeView1.Nodes.Find()

Good Day,
Say I have a simple application that copies files to another folder and I'm using File.Copy to recursively copy the file.
Is there a way to query the the progress of the File.Copy method?
Thanks!
