Upload files without prompting for filename

sbs · 2013-01-03

Hi

For this pojeckt am I using NAV 2009 SP1.

I want to upload all files in a folder into nav. In classic this works fine but now I want to use rtc...
I can get rtc to upload a file but I always have to choose my file first. (I don't want to do that)
Is there a way to upload every file in the folder without asking anything of the user?

like this in classic

InFile.SETRANGE(Path, SalesSetup."My File Folder" + '\');
InFile.SETRANGE("Is a file", TRUE);
IF InFile.FINDSET THEN BEGIN

// here some code for taking care of the textfile...

REPEAT UNTIL InFile.NEXT=0;

I think there is no way to use file virtual table on client, as code is execute on middle-tier. You can use windows scripting host automation (instantiated on client) to list folder contents.

sbs · 2013-01-03

Thank You,
do you happen to have an example or link to look at how to use this automation?

Look for azwierzchowski reply.

That solution works fine... in classic.
There was also a solution for RTC if you have 2009 R2, unfortunately we are using 2009 sp1

This should work ok for rtc, just define windows scripting host variables to be run on client.

sbs · 2013-01-10

How do i define windows scripting host variables to be run on client? :?:

The program stops on the line
LautFolder := LautFileSystemObject.GetFolder(MyFolder);

All above have helped me a bit on my way, but ...

If I try to run it in RTC I got the following error: Could not compile assembly...

I have commented out code and it run fine if I comment out these two lines
WHSFile := FilesCol.Item(i);
ltxtFileName := WHSFolder.Path + '\' + WHSFile.Name;

Any ideas?

Here is my code:

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

// If the folder does not exist, exit
IF NOT WHSFileSystemObject.FolderExists(MyFolder) THEN BEGIN
CLEAR(WHSFileSystemObject);
EXIT;
END;

WHSFolder := WHSFileSystemObject.GetFolder(MyFolder);
WHSFiles := WHSFolder.Files;

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

// ========================================================================
// Use a VBScript to fill a 'Microsoft Scripting Runtime'.Dictionary
IF ISCLEAR(Script) THEN
CREATE(Script,TRUE,TRUE);

Script.Language := 'VBScript';
//variable LautFolders is visible in script as FoldersByName
Script.AddObject('FilesByName', WHSFiles);
//variable FoldersCol is visible in script as FoldersById
Script.AddObject('FilesById', FilesCol);

//copy objects using VBScript
txtCR := '';
txtCR[1] := 13;
txtcode :=
'dim f1' + txtCR +
'For Each f1 in FilesByName' + txtCR +
' FilesById.Add (FilesById.Count+1), f1' + txtCR +
'Next' + txtCR;
Script.ExecuteStatement(txtcode);
CLEAR(Script);
// ========================================================================

FileCount := FilesCol.Count();
FOR FileInt := 1 TO FileCount DO BEGIN
WHSFile := FilesCol.Item(i); <---- Here is the problem!
ltxtFileName := WHSFolder.Path + '\' + WHSFile.Name;
// ==========================
// Here you do what you want to do with the file...
// MESSAGE(ltxtFileName);
// ==========================
END;

CLEAR(FilesCol);
CLEAR(WHSFileSystemObject);

Can you please post c# assembly? I think c/al -> c# translator messing up with your code. Would be interesting to see how this looks in c#.

sbs · 2013-01-14

Hi

I don't know how to do that :oops:

ppavuk · 2013-01-14

set your server to debug mode (google howto edit config)
after first client run somewhere under "C:\ProgramData\Microsoft\Microsoft Dynamics NAV\60\Server\MicrosoftDynamicsNavServer\source\" on server machine you will find c# files for each object.

for me this line isn't looks good:

filename = new NavText(150, wHSFolder.InvokePropertyGet<String>(@Path)+@\+wHSFile.InvokePropertyGet<String>(@Name));

I am not a c# expert, but what happens if you just hardcode path in c/al, something like

filename := 'c:\temp\test.txt'

Looks that c/al -> c# translator can't convert your expression into valid c# code.

sbs · 2013-01-22

thanx

but it fails even if i comment away that line, it is the line before that that is the problem.

And i can't hardcode it to something - the whole idea is to get those filenames :-)

I have now tried the same code in 2009 R2 and i get the same errortext

deV.ch · 2013-01-22

What do you try to achieve with the VBScript part? Do you need the files in a specific order?

ppavuk · 2013-01-22

The thing is - you need to find out line which can't be compiled in c# and change it to make it compilable.

deV.ch · 2013-01-22

The OP said which line produces the error:

FileCount := FilesCol.Count();
FOR FileInt := 1 TO FileCount DO BEGIN
WHSFile := FilesCol.Item(i); <---- Here is the problem!
ltxtFileName := WHSFolder.Path + '\' + WHSFile.Name;

I would like to know why you even need the whole VBScript part? Why not looping over the WSHFiles Collection?

sbs · 2013-01-22

yes, I tried to do that
WHSFile := WHSFiles.Item(i);

But then it complains over my parameters.
the WHSFiles are sorted by names - and I don't know the filenames

all files are there
FileCount := WHSFiles.Count(); works fine
I just don't can't get the names from them :roll:

deV.ch · 2013-01-22

Please have a look at this, especially page 2 (if you don't have already) http://www.mibuso.com/forum/viewtopic.php?f=5&t=7855&start=15

If you can, i would recommend using .Net interop instead. There you don't have such limitations. The collections work as expected in the System.IO Namespace you will find all you need (Directory Class which returns file names as string)

Or if you must stick to automations, try the "Microsoft Shell Controls And Automation'.Shell" instead.

MSShell	Automation	'Microsoft Shell Controls And Automation'.Shell	
MSFolder	Automation	'Microsoft Shell Controls And Automation'.Folder	
MSFolderItem	Automation	'Microsoft Shell Controls And Automation'.FolderItem	

Create(MSShell, TRUE, TRUE);

MSFolder := MSShell.NameSpace('C:\Temp\');
For i := 1 TO MSFolder.Items.Count DO BEGIN
  MSFolderItem := MSFolder.Items.Item(i);
  Message(MSFolderItem.Path);
END;

sbs · 2013-01-22

Thanx,

In the thread it says that .NET only works with R2, I am using 2009 sp1.
But I will try "Microsoft Shell Controls And Automation'.Shell"

What do you try to achieve with the VBScript part? Do you need the files in a specific order?

No specific order. I just want the name of all the files in a specific folder.

sbs · 2013-01-22

=D>

The MSFolder version works!

Thank You all for your suggestions and links

Here is my final code (anyway "final" before put into real context)
