Problem running remote process using WMI [modified]

Hi,

I urgently need to get this program running. I'm trying to remotely connect to a server using WMI (which is all fine) and then run an executable as a process on the server.

I currently get the error "Public member 'string' on type 'Uinteger' not found". I think this is something to do with the InvokeMethod line, as most examples have 'null' where it has 'Nothing'. However null is not allowed in VB.NET 2005 - it suggests using system.dbnull which doesn't work either.

 <br />
' Get the object on which the method will be invoked<br />
                    Dim processClass As New ManagementClass<br />
                    processClass = New ManagementClass("Win32_Process")<br />
                    processClass.Scope = scope<br />
                    ' Get an input parameters object for this method<br />
                    Dim inParams As ManagementBaseObject = processClass.GetMethodParameters("Create")<br />
                    ' Fill in input parameter values<br />
                    inParams("CommandLine") = patchcommand 'This is a string containing the command<br />
             <br />
<br />
                    ' Execute the method<br />
                    Try<br />
                        Dim outParams As ManagementBaseObject = processClass.InvokeMethod("Create", inParams, Nothing)<br />
                        Dim obj As Object = outParams("ReturnValue")<br />
<br />
                        'Check for an error<br />
                        If obj.ToString <> "0" Then<br />
                           'Error occurred<br />
                        End If<br />
                    Catch ex As Exception<br />
                        'This catches any other errors from trying to run the process<br />
                        MessageBox.Show(servername & " - Error running process - " & ex.Message & vbCrLf & ex.ToString)<br />
                       <br />
                    End Try<br />

Thanks. I've edited the title. I'm not looking for source code by the way, I just posted my code to show how I'm trying to do it.

I think the code is correct except for that one line being wrong in some way.

I've changed the way I'm doing it now. I'm getting a return code of 9 but I can't seem to find out what these codes mean.

New code -

Dim processClass2 As ManagementClass = New ManagementClass("Win32_Process")
processClass2.Scope = scope
Dim inParams2 As ManagementBaseObject = processClass2.GetMethodParameters("Create")
Dim startup As ManagementClass = New ManagementClass("WIN32_ProcessStartup")
startup.Scope = scope
inParams2("CommandLine") = patchcommand
inParams2("ProcessStartupInformation") = startup
Dim outParams As ManagementBaseObject = processClass2.InvokeMethod("Create", inParams2, Nothing)


'Check for an error
If (outParams("ReturnValue").ToString) <> "0" Then
    'Add error to listview
    Dim itms1 As New Windows.Forms.ListViewItem.ListViewSubItem _
        (itmp, "Could not start process. Error code " & (outParams("ReturnValue").ToString))
    itmp.ForeColor = Color.Red
    itmp.SubItems.Add(itms1)
    itmp.Checked = True
    'Skip to next file
    GoTo skipfile
End If

I suggest you check the contents of your patchcommand variable.

Thanks very much for the codes.

I'm not sure about the escape characters in the variable. It's set to -

patchcommand = " ""\\server\folder\folder\WindowsServer2003-KB958644-x86-ENU.exe "" /quiet"

And I want it to run "\\server\folder\folder\WindowsServer2003-KB958644-x86-ENU.exe" /quiet

I've tried it with \\\\server\\folder\\folder\\WindowsServer2003-KB958644-x86-ENU.exe which also seems to fail.

The usual error code that comes back is 9 now - I was getting 8 before I started mucking around with escape characters.

There is a PrintDialog class. Use that.

Hi all. I am currently looking to insert a value into a memo field in vfp using a odbc connection but keep getting a error (ERROR [22018] [Microsoft][ODBC Visual FoxPro Driver]Data type mismatch). Does anybody know if this is supported by the odbc connection object or does anybody have sample code to do this. The sql is correct this thing just fails with the odbc connection.

You say that the SQL is correct, what type of database have you tested it on? The reason I ask is because I believe that the required type of data can vary between database engines.

If you haven't done so already (and I apologise if you have), I would test the SQL on the VFP database directly.

I notice multiple booleans that appear as single character strings ('T' or 'F'). Are those
fields actually character type or boolean type? In VFP .T. and .F. are used to indicate
booleans. If you are using parameters for the ODBC command and assign a boolean value to them it should handle them for
you, but if you are specifying their values in the command text then you may need to use the VFP boolean syntax.

Hope in one hand and poop in the other; see which fills up first. Hope and change were good slogans, now show us more than words.

FindFile file type question

Hi all,

I am new to vb and I am trying to get the file type of every file found during findfile here is my code:

iSearchHandle = FindFirstFile(SrcDir, pFindFileBuff)
    If iSearchHandle <> INVALID_HANDLE_VALUE Then

        strFile = TrimNull(pFindFileBuff.cFileName)
        Do While strFile <> ""
            Do While FindNextFile(iSearchHandle, pFindFileBuff)
            strFile = TrimNull(pFindFileBuff.cFileName)
            If strFile <> "." And strFile <> ".." Then
            strFile = strDir + "\" + strFile
            'strLen = Len(strFile)
            
            fileType = Right$(strFile, 4)

I tried using Right$ to get the file type for example "TonyRobertson.ppsx", ,"version2.5.0.doc", "IMIT031211_TonyRobertson.ppt" and "MARBLES.G4"

by using that I get ppsx, .doc, .ppt and S.G4, is there another way to get the right format?

Thanks,
Jj

Hope you are using VB6.
There are two options to get the file type e.g.
1. Split the filename using (.) dot character and get last element in array.
2. Use FileSystemObject, that provides a lot more options on file information. For more information : Click[^]

PS: If you are using VB.NET then there are lot of utility classes in System.IO Namespace[^]
