Code to "wake up" a mapped HDD on a server

Votuc

I am trying to display a PDF file on a client computer through the RTC from a mapped drive on the server computer.

I am using HYPERLINK() which works sometimes and other times does not. I believe this is because the mapped folder is not ready to be accessed fast enough.

What could I do to force the mapped hard drive to be ready (perhaps save over a file each time?) then perhaps a <timer> function to wait 5 seconds or so to make sure it is ready before the HYPERLINK function? :-k

I don't believe it has to do with it accessing it fast enough.
Do you receive an error message?
If it doesn't open - go to My Computer & see if it says "Network Drive" or "Discontected Network Drive".
If it's disconnected you need to double click on it to reconnect.

I believe on your server, does it have file server role?, that you can set a setting on shared drives that does or does not disconnect login users depending on what you want. Or you can set a time limit.

Can't you use UNC paths? Which eliminate the whole mapped drive problem.

I am not sure how to do that. I see an example of FILE.OPEN in the Help files:

Variable: TestFile
Data type: File



TestFile.TEXTMODE(TRUE);
TestFile.WRITEMODE(FALSE);
TestFile.OPEN('C:\temp\simple.xml');

How do I alter this to display a PDF? I tried simply changing the file path to my PDF file and I got an I/O error.

UNC (Universal Naming Convention) paths are presented in the format \\sharename\folder. An example might be \\fileshare\datafolder.

In your example you would define a text variable, assign the UNC path to it, and pass it to the create call.

Variable: TestFile
Data type: File

Variable: FilePath
Data Type: Text (100)

FilePath := '\\fileshare\datafolder\simple.xml'
TestFile.TEXTMODE(TRUE);
TestFile.WRITEMODE(FALSE);
TestFile.OPEN(FilePath);

of course you need to specify a valid UNC path for your network. You can use Network Neighborhood to browse and then copy and paste the path

If you want the file to be opened in the default application, then you'll have to use the HYPERLINK-function like this:

HYPERLINK('\\fileshare\datafolder\simple.pdf');
