Creating a remote share using WMI in C#

Ben Taylor

Hi There,
I was wondering if anyone can help me with the following problem:
I have written an app to easily create a share on a remote computer utilizing WMI, however I cannot seem to get it working, I end up with a "Provider is not capable of the attempted operation" error. I have full admin access to the remote server so permissions should not be an issue. Any help or suggestions would be greatly appreciated. Below is the code in question:


try
{ 
ManagementPath winSharePath = new ManagementPath("Win32_Share");
ManagementScope winShareScope = new ManagementScope(@"\\server01\root\cimv2");
ManagementClass winShareClass = new ManagementClass(winShareScope,winSharePath,null);
ManagementObject shareObject = winShareClass.CreateInstance();
shareObject["Path"] = @"E:\Test";
shareObject["Name"] = "TestShare$";
shareObject["Type"] = 0;
shareObject["Description"] = "Test Share Description";
PutOptions shareOptions = new PutOptions();
shareOptions.Type = PutType.UpdateOrCreate;
shareOptions.Timeout = TimeSpan.MaxValue;
shareObject.Put(shareOptions);
}
catch (Exception err)
{
MessageBox.Show(err.Message);
}

Cheers
Ben

hello,
here is my code.

Dim moSearch As Management.ManagementObjectSearcher = New Management.ManagementObjectSearcher("Select * from Win32_POTSModem")
            '' get serach data
            Dim oc As Management.ManagementObjectCollection = moSearch.Get()
            '' list of every modems install in computer
            For Each m As Management.ManagementObject In oc
                '' check modem status
                '' status "OK" means ready to use
                If m("Status").ToString() = "OK" Then

                    ''' properties list
                    ''' http://msdn.microsoft.com/en-us/library/aa394360%28VS.85%29.aspx
                    If m("Name").ToString & "[" & m("AttachedTo").ToString() & "]" = oldNm Then
                        Dim p As String = m.Item("Name")
                        m.SetPropertyValue("Name", newNm)
                        Dim moo As New Management.ManagementOperationObserver()
                        Dim shareOptions As New Management.PutOptions()
                        shareOptions.Type = Management.PutType.UpdateOrCreate
                        shareOptions.Timeout = TimeSpan.MaxValue
                        m.Put(shareOptions)
                        'm.SetQualifierValue("Name", newNm)
                        Exit For
                    End If
                End If
            Next
for above code i got error like "Provider is not capable of the attempted operation", when i call put function.

any solution.

Figured it out! I was using the wrong method I should have been using the InvokeMethod of the ManagementClass object. Correct code is below incase it helps anyone else.
ManagementPath winSharePath = new ManagementPath("Win32_Share");
ManagementScope winShareScope = new ManagementScope(@"\\server01\root\cimv2");
ManagementClass winShareClass = new ManagementClass(winShareScope, winSharePath, null);
ManagementBaseObject shareParams = winShareClass.GetMethodParameters("Create");
shareParams["Path"] = @"E:\Test";
shareParams["Name"] = "TestShare$";
shareParams["Type"] = 0;
shareParams["Description"] = "Test Share Description";
ManagementBaseObject winShareResult = winShareClass.InvokeMethod("Create", shareParams, null);

Cheers

if you want to test your code without running your app.
