Call Function In Parent Form?

I will need call function in the main form. what's the right way to do this?
now, I pass the main form when create the class. but I guess the right way is to raise the event in main form.

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?
Sep 14, 2010I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

Nov 24, 2010I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.
