Thanks Klaas for your reply. Issue has been resolved. There was an issue with AOS service account.

Hi Ajit,

What is the error you’re getting?
Are you using a local path (C:\…) or UNC path (\\server\…)?
Is it possible to copy your code here?

I want to delete files using WINAPIServer in AX 2012. When I change class run on type to “Client” then its is working but when I am changing to server, it doesn’t work. Any pointer would be helpful.

Thanks,
Ajit

Hi Ajit,

Can you try the same as Micheal (comment 8), a try/catch to capture the .net exception.
This might point you to the problem.

Hi Klass,

I am using below code for moving file from one location to another location. Location defined on parameters

In Location – \\ServerName\FolderName
Out Location – \\ServerName\Out Folder Name

But I am getting – ClrObject static method invocation error.
I am ruuning code on server. Any help will be appreciated.
Tell me if I am doing something wrong here.

permissionSet.add(new FileIOPermission(fileName,#io_read));
permissionSet.add(new InteropPermission(InteropKind::ClrInterop));

[path, filenameL,fileExt] = fileNameSplit(filename);
fileNameTo = CustParameters::find().CSVArchieveLocation +’\\’+ fileNameL + ‘_’ +strrem(strrem(date2str(SystemDateGet(),213,2,1,2,1,4),’//’),’ ‘) + ‘_’ + time2str(timenow(),3,3)+’.csv’;

permissionSet.add(new FileIOPermission(fileNameTo,#io_Write));
CodeAccessPermission::assertMultiple(permissionSet);
System.IO.File::Move(fileName,fileNameTo);
CodeAccessPermission::revertAssert();

Thanks,
Ajit

I am having this warning being logged in the Event Viewer. Does this problem may cause stability issues in the server? Because after a number of entries, it goes down unexpectedly …

Any help will be appreciated.

It’s kinda strange.
You are right, @”C:\” works fine.

But for example @”\\serverName\Share” does not.
In windows explorer I can access those shares and share permissions are set for Everyone.

It’s clearly a network permissions problem.

I’ll do some more research and keep you posted.

Hi Matic,

I tested you code like this and it ran fine:

static void klForGetDirs(Args _args)
{
Set permissionSet;
System.Array files;
int i, j;
container fList;
str filename;
;

permissionSet = new Set(Types::Class);
permissionSet.add(new FileIOPermission(@"C:\", "r"));
permissionSet.add(new InteropPermission(InteropKind::ClrInterop));
CodeAccessPermission::assertMultiple(permissionSet);

files = System.IO.Directory::GetDirectories(@"C:\");

for( i=0; i {
fList = conins(fList, conlen(fList)+1, ClrInterop::getAnyTypeForObject(files.GetValue(i)));
}

for(j=1;j<= conlen(fList); j++)
{
fileName = conpeek(fList, j);
info(fileName);
}
}

I think the error “ClrObject static method invocation error.” indicates that the parameter you provide to the function is incorrect. Try a fixed path ‘like @”C:\” to see if that works. Then you know that is (or isn’t) the problem. As I’ve said in previous comments, AX behaves a bit strange when it come to filepaths (and escaping those slashes), I have trouble figuring that out too :).
