Delete file on Client

lollygag · 2011-11-01

Hi

Here is my problem.

User wants to link a file on their pc (using the RTC).
When link is saved the file is uploaded to the server, and the link is changed.
File on the client needs to be deleted.

I have sucessfully (after lots of trial and error) managed to upload the file and change the URL in the link. However I cannot seem to delete the original file from the client.

Any ideas greatly appriciated...

Yes, this RTC client is strange in a way.

Could you show how you did the upload and change? I want to do something simular. I have some code for the delete on the client. Will let you know tomorrow.

You can create an instance of the FileSystemObject on the client side through automation and use it to delete the file.

Hi

How do I create an instance of the FileSystemObject on the client side?

I can see this option for dotNet but not Automation. And I only see the FileSystemObject as an automation.

Am I missing something really obvious? :oops:

@lollygag
Could you show me the NAV source code of what you did?

    PROCEDURE EraseOnClient@1000000023(VAR vPtFileNamePath@1000000001 : Text[1024]);
    VAR
      LaScriptControl@1000000003 : Automation "{0E59F1D2-1FBE-11D0-8FF2-00A0D10038BC} 1.0:{0E59F1D5-1FBE-11D0-8FF2-00A0D10038BC}:'Microsoft Script Control 1.0'.ScriptControl";
      CR@1000000002 : Text[1];
    BEGIN
      IF ISSERVICETIER THEN BEGIN
        IF CREATE(LaScriptControl,TRUE,TRUE) THEN BEGIN
            CR := ' '; CR[1] := 13;
            LaScriptControl.Language := 'VBScript';
            LaScriptControl.AddCode(
            'set fso = createobject("Scripting.FileSystemObject")'+CR+
            ''+CR+
            'function FileDelete(thisFile)'+CR+
            'if fso.FileExists(thisFile) then'+CR+
            '  fso.DeleteFile thisFile'+CR+
            'end if'+CR+
            'end function');
            LaScriptControl.Eval('FileDelete("'+vPtFileNamePath+'")');
        END;
      END ELSE BEGIN
        IF EXISTS(vPtFileNamePath) THEN BEGIN
          ERASE(vPtFileNamePath);
        END;
      END;
    END;

Haven't tested it yet. Will do later this day when opening my project

Thank you mdPartnerNL, that works great. Below is the code you requested.
I hope this helps.

MoveRTC()
FileToUpload := GetFilename(URL1);
FolderName := GetFoldername(URL1);

PurchSetup.GET;
PurchSetup.TESTFIELD("Attachment Sharename");

FileVar.CREATETEMPFILE;
FileVar.CREATEINSTREAM(IStream);
DOWNLOADFROMSTREAM(IStream,'','<TEMP>', '',MagicPath);
FileVar.CLOSE;

FOR i := STRLEN(MagicPath) DOWNTO 1 DO BEGIN
  IF MagicPath[i] = '\' THEN BEGIN
    MagicPath := COPYSTR(MagicPath,1,i);
    i := 1;
  END;
END;

IF ISCLEAR(FileSystemObject) THEN CREATE(FileSystemObject,TRUE,TRUE);

FileSystemObject.CopyFile(FolderName + '\' + FileToUpload,MagicPath + '\' + FileToUpload);

UPLOADINTOSTREAM('','<TEMP>','',FileToUpload,IStream);
 
NewFilepath := PurchSetup."Attachment Sharename" + GetFilename(URL1);

FileVar.WRITEMODE(TRUE);
FileVar.CREATE(NewFilepath);
FileVar.CREATEOUTSTREAM(OStream);
COPYSTREAM(OStream,IStream);
FileVar.CLOSE;

URL1 := NewFilepath;
IF MODIFY THEN;

GetFilename(str1 : Text[250]) : Text[250]
WHILE STRPOS(str1,'\') > 0 DO BEGIN
  i+=1;
  str1 := COPYSTR(str1,STRPOS(str1,'\')+1);
  IF i > 50 THEN ERROR('');
END;
EXIT(str1);

GetFoldername(str1 : Text[250]) : Text[250]
FOR i := STRLEN(str1) DOWNTO 1 DO BEGIN
  IF str1[i] = '\' THEN BEGIN
    str1 := COPYSTR(str1,1,i);
    i := 1;
  END;
END;
EXIT(str1 + '\');
