how can i do two things at oncce

Hi

I am tring to write a small ftp client in vb.net, i can get it do download file using wininet.dll and ftpgetfile to download the file, but as the files i want to download may be large i need some sort of progress indicator to show how much of the total is downloaded.

i have tried using the file size.maxvalue indicatiors, but this won't work cos when i call the ftpgetfile, the system is stuck until then entire file is downloaded. how can i make this so it has a progress bar or shows the user how much has come down.

any help would be much appreciated

cheers

You need to do some multithreading. You need to put the download operation on a seperate thread. Here is an article on the MSDN library site that should give you more information than you need to do this:

Have fun.

Well threading in .net is cool but good http/ftp dlls should provide events to allow for download progress checking.

You should fire the application.doevents method every now again so that the screen gets updated.

You could also use a timer, and place the doevents in a timer.

You shouldn't have to do that in VB.Net, at least not for what is being asked.

For the problem at hand, having the download process and checking on a seperate thread is going to be ideal. You don't want something locking up the main form, and a seperate thread will do this. Have an object fire events to the main form telling the current status of the download. Then handle the UI implementation there.

You are right, it is messy and it will sure to be a problem later.

Creating another thread is the best solution.
