Threading library for optimising compiler

[Cableguy]

I think I will go with a separate executable handling the datafile and cheking the dates....
As I understand, and please confirm this, if I use something like my about panel as a pop-up, the code will NOT be halted...as it hapens qith a message box....Correct?

In that case you might want to use the Process object in the threading library, rather than B4PPC "Shell", as Process can tell you when the separate app terminates and you could then pick up the results from a file.

Your about panel seems to NOT halt the main code of a B4PPC app.

Thanks Agraham...
All good news, but I do not need to do a process separation, because the checking is simple...then I just take the data and have it pop-up...
It will be a "silent" app, as it will be minimized and only show in the taskbar...
Thanks for all your input...
If you'd like i can post the code as far as I have it, but it is in portuguese language, but fairly simple to understand..
I plan to have the "Main" app ready tonight...

I assum that it will use the same data file as the main app. You will need to check what happens if this silent app tries to open the file at the same time as the main app (and vice versa) trap any errors and account for that in the code of both apps.

I think I have it covered, as I use the Loadcsv method of the table control, so the file lock should be kept to a minimum, and since the silent app will be running at a known time, the user will know when NOT to husle the Main app...
Still I will post my app so that, if you be so kind, take a look and share with me your thoughts....

Sorry - bad practice - NEVER rely on a user to do the right thing

Hi, agraham! It seems that your library is not work with HTTP library...
On the device, attached code raises an error

Please read the help, Thread pitfalls -> GUI operations, and look at the sample app. You cannot access GUI controls from a thread without causing an error. This is why I provided thread events. See this mod to your original code which now works.

Thanks for you reply, agraham, but in my Glofiish M700 your code still causing an error

UPDATE: Hmm... This error calls "NotSupportedException" :-) and if i ignore this error (choose to continue), the html code appears in TextBox...

[agraham]

I assume you mean that an error occurs when you run the modified 11.sbp code I posted. Next time please be more exact in describing exactly what you see happens rather than just saying an error occurred.

There is no error trapping in the thread in that code. In production code a thread subroutine should always have an errorlabel statement to trap errors otherwise B4PPC error handling will try to put up a message box from the thread which will itself cause an error as it is running on the threads' thread, not the GUI thread. Please try the attached code which should run without error in all situations - at least it does on my device.
