Creating Share not working porperly for W98/me

[Fritz]

I am creating a share for my app-folder:


Imports System.Management

On BTN_CLICK:

Dim apath As String = IO.Directory.GetCurrentDirectory()

Const IsFileShare As Integer = 0
Const Max_Connections As Integer = 10
Dim Share_Info As String() = {apath, "MyApp", 0}
Dim Win_Shares As ManagementClass = New ManagementClass("Win32_Share")
Try
Win_Shares.InvokeMethod("Create", Share_Info)
Catch ex As System.Management.ManagementException
MessageBox.Show(ex.ToString)
Return
Finally
Win_Shares.Dispose()
End Try
MessageBox.Show("Share: " + Share_Info(0) + " succeed!")

This works fine for W2000/XP. It also creates a share on Win98/Me, but ReadOnly. And of course like that the App will not run on client machines.

I have also tried with APIs, all kind of stuff, also with VB6 code, but the code above still works best, except for this silly little detail, and I cannot find a way to change the ReadOnly-mode to ReadWrite.

Anybody got an idea?

It might have something to do with the ACL. Try forceing the permissions on the creation of the share.

Yes, of course, I think it has to do with the ACL. But I find no way to force it under W98. If I use API, there are 3 different structures:

shi_2 - for W2000/XP
shi_502 - for NT/2000/XP
shi_50 - for W95/98/Me

And the shi_50 just seems to have no entry for ACL or security descriptor. I simply dont know enough about these declarations and the help stuff also is only confusing me.

As I said: the WMI above at least does everything right for W2000/XP (and NT too I think). And in W98/Me it creates the share, but ReadOnly.

I am trying a workaround now, calling the file properties dialog, so the user can at least set the share without having to search the file first. That works but its not really a fine way.

I have already seen these articles. This works all with the netapi32.dll and the shi_502. But W98/Me only accept svrapi.dll and the shi_50. Also in W2000/XP there is no need to declare ReadWrite permissions because any share is ReadWrite. The Items concerning permissions only handle with passwords and thats not the problem.
