iOS Question FTP question

[moore_it]

Hi all,

when i download several files from and ftp server, my program in debug works fine, instead in release mode download some files and waiting forever
I need to slow the download process with a for cycle ...

It's true ?
Or a bug ?

Thanks

Can you post your code?

 

[moore_it]

sure

This code work fine in debug, infinite loop in release

 

[Erel]

Can you try to build a small project with only the relevant FTP code that reproduces this issue?

Where exactly is the infinite loop? In FTP_DownloadCompleted?

 

[moore_it]

when i try in debug mode the FTP_DownloadCompleted work fine i don't know where is the loop.
If you want i give you ma server account for testing ...

 

[moore_it]

if i insert a for cycle type in ftp_DownloadCompleted

for i = 0 to 100000000
next

also in release work fine ....

when i try in debug mode the FTP_DownloadCompleted work fine i don't know where is the loop.
If you want i give you ma server account for testing ...

Please try to reproduce it in a new project with only the FTP related code.

There are several problems in your code:
1. 1ms interval is too short for a timer. It may cause the main thread to be blocked by this timer.
2. Your code actually creates many timers with this interval:

Case "WP" 'work in progress
     myTimer.Initialize("tim",1)
     myTimer.Enabled = True

You are creating a new timer with this interval each tick. You don't need to initialize a new timer for the timer to continue ticking.

3. It is not really a problem however the timer is not needed here at all. Use the DownloadCompleted event to update whatever you want to update.
