Hello Experts , in my code I wrote code to print a Document like below

Print()

{

IF NOT TryPrintDocument(Path,Name) THEN
ERROR('Not able to print %1. \\ERROR: %2',Path+Name, GETLASTERRORTEXT)

}

[TryFunction] TryPrintDocument(PathP : Text;NameP : Text)

{
ProcessStartInfo := ProcessStartInfo.ProcessStartInfo(PathP+NameP);
WITH ProcessStartInfo DO BEGIN
Verb := 'Print';
CreateNoWindow := TRUE;
WindowStyle := ProcessWindowStyle.Hidden;
END;
Process.Start(ProcessStartInfo);
CLEAR(ProcessStartInfo);
CLEAR(Process);
CLEAR(ProcessStartInfo);

}

But While running this code I am getting error

Error :

Not able to print C:\Temp\test.pdf.

ERROR: A call to System.Diagnostics.Process.Start failed with this message: No application is associated with the specified file for this operation

Hi, a bit of a guess - maybe just check that the system has a default printer?

If not, then do you know what line it errors on, and what kind of variable is ProcessStartInfo?

Hello Lars Lohndorf-Larsen

In my system default printer is setup.

I am getting an error at Process.Start(ProcessStartInfo); Line

and ProcessStartInfo is DotNet Variable .

Hi,

Thanks for more details. What sub type is the DotNet variable? Maybe if you can attach or copy in the whole object (exported as txt)? And would we be able to reproduce it?

Subtype of ProcessStartInfo DotNet Variable is --> System.Diagnostics.ProcessStartInfo.'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

Hi, and thanks for more details. I can also repro now. I am pretty sure that this is a setting in Windows as for example mentioned here https://stackoverflow.com/questions/21032151/no-application-is-associated-with-the-specified-file-for-this-operation-vb-net . You will see that the code works fine on a .docx file, but not on a .pdf file. And you see the same if you right-click these types of files in Windows Explorer - .docx has a "Print" option. .Pdf doesn't.

I don't know if you need to install another pdf renderer - mine is set to MSEdge, or mabye somewhere in registry can fix it, but you need to get Windows to add a "print"-action to pdf documents somehow. Sorry I am not sure about how to do that but I hope this helps you forward and let us know if you find out,

/Lars

Repro code:

//Print()

Path := 'c:\temp\';
Name := 'Doc.docx';
Name := 'Test.pdf';

///IF FALSE THEN
IF NOT TryPrintDocument(Path,Name) THEN
ERROR('Not able to print %1. \\ERROR: %2',Path+Name, GETLASTERRORTEXT);

///TryPrintDocument(Path,Name);

MESSAGE('Done.');
END;

}
CODE
{
VAR
ProcessStartInfo@1000 : DotNet "'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.ProcessStartInfo";
Process@1001 : DotNet "'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.Process";
Path@1002 : Text;
Name@1003 : Text;

[TryFunction]
[LineStart(15)]
LOCAL PROCEDURE TryPrintDocument@1(PathP@1000 : Text;NameP@1001 : Text);
BEGIN
ProcessStartInfo := ProcessStartInfo.ProcessStartInfo(PathP+NameP);
WITH ProcessStartInfo DO BEGIN
Verb := 'Print';
///Verb := '';
CreateNoWindow := TRUE;
///WindowStyle := ProcessWindowStyle.Hidden;
END;
Process.Start(ProcessStartInfo);
CLEAR(ProcessStartInfo);
CLEAR(Process);
CLEAR(ProcessStartInfo);
END;

Just one more thing:

If you need to research this further in non-NAV forums, then C/AL example won't help much, so below is C# code that can reproduce the same thing completely outside of NAV, in case it can help you bring this up in Windows / c# forums.
