Hello Experts

I have windows application developed in vb.net.
I am uploading a file in FTP and so it take a while to Upload.
At this time, I want to make the form look that it is doing something, and I don't want user to click on anything in the form. It is not just progress bar. It is something related to progress bar where user should not be allowed to click on the form controls. How can this be done?

could you post the code you used to do the uploading to the FTP server(without the username and password)

MasterCodeon 19-Dec-14 14:58pm

oh and does the progress bar have to move?

sudevsu 19-Dec-14 15:08pm

I don't need progress bar to move but I just want to make the form look like "it cannot be clicked" you know how apple does little circle while updating the phone. I want the form like that.
And Yeah by the way, I didn't do much with keeping the File in Server. I just used File.Copy("sourcepath","destinationpath"). That's it.

ah ok.
i have never seen an iPhone update but i do know how to disable all the controls in a from at will, would that partially solve your problem?

sudevsu 19-Dec-14 15:17pm

Yeah that will.

Solution 1

ok so what you want to do is first you want to define a variable stating weither or not the controls on the form are enabled like this(its a Boolean variable):

VB

Dim FormEnabled As Boolean

then when you want to enable or disable the form controls you just illiterate through the Controls property of Me:

VB

If FormEnabled = False Then
    For Each Item As Control In Me.Controls
        Item.Enabled = FormEnabled
    Next
Else
    For Each Item As Control In Me.Controls
        Item.Enabled = FormEnabled
     Next
End If

and then before you run this if statement you set the Boolean to either true or false like this:

VB

FormEnabled = True
''Or
FormEnabled = False

if you would like i can improve this post with this control disabling method integrated into your code if you give me your code.
Waraning: this will disable all of the controls in the application until you reenable them.
tell me if this helps,

Well, I tried doing this, But the form controls are enabled to true even after doing this. Moreover Form says "Not responding" till the file is properly placed in FTP and then shows as normal form once files are placed in FTP. This is weird and killing my Friday :-/

MasterCodeon 19-Dec-14 15:54pm

and are you using the System.IO.File class?

MasterCodeon 19-Dec-14 15:51pm

well right before the line of code that uploads your file to the server set the "FormEnabled" variable to true

sudevsu 19-Dec-14 16:02pm

I did this way before you posted the code. I didn't get it done. I mean it goes to not responding and comes back but not the way we are thinking it should. May be it does this because There is lot of load of FTP Server. I think I need someother ways

MasterCodeon 19-Dec-14 16:07pm

that might be it but it also might be the fact that you are doing the file copy on the same thread as the application it self.
i had that same problem when i would use the System.Speech to do Text to Speech.
the UI would freeze up until the program stopped speaking.
so i asked how to fix it here and the answer i got was that i had to use the SpeakAsync method instead of the Speak method.
this is due to the fact that SpeakAsync will run the TTS(Text To Speech) operation on a different thread than the UI(or sometimes called the Winform, Application) thread.
I looked and there is no CopyAsync methods so of you know how try running your Copy operation on a separate thread.

MasterCodeon 19-Dec-14 16:09pm

sorry i meant to say: so if you know how to, try running your Copy operation on a separate thread.

sudevsu 19-Dec-14 16:12pm

Oh yeah that's true I am doing it on same thread. I don't know how to copy from a different thread. If you have any ideas let me know I would try that.

here is an article i found on codeproject that might be of big help:
http://www.codeproject.com/Articles/16174/Multithreading-Backup-Utility

and also you might try using a BackgroundWorker

MasterCodeon 19-Dec-14 16:21pm

wow why couldn't i have found this article when i actually needed it?
this article has explained mutlithreaded applications in a way that seems soo simple to me and i get it!
man that would have been nice a while back

MasterCodeon 19-Dec-14 16:17pm

a BackgroundWorker is a control you can find in the toolbox in the designer, if you didn't know.

Philippe Mori 19-Dec-14 17:56pm

Why disabling all controls and not the form itself? Or put controls in a panel? That way, user can minimize or move the main window. In such case, you have to prevent closing.
