Well, I'm not sure...
Normally, I get the 'Name' attribute, but, my code is written to allow the user to select the desired attributes. When I selected 'ShareName', I had no errors.
Have you confirmed that you can get the sharename using the WMICodeCreator?
|

|
|
Yeah, and the crazy thing is that I can see the list of sharenames in the creator, but when I execute the code (from the creator), it gives an access denied error, and fails.

Ok, I figured it out. Some printers don't have share names (because they're a local printer, or for some other reason). Those printers that don't have share names would return a null result for their share name, and that is what was causing the error. I changed the query to have a where clause: "WHERE ShareName IS NOT NULL", and that fixed the issue.

i = cmd.ExecuteNonQuery()
MsgBox("record inserted")
Catch ex As Exception
End Try
cn.Close()</code>

you can use this code also:
Public Function Query(ByVal SQL As String, ByVal OLEDBCon As OleDb.OleDbConnection, ByRef DS As DataSet) As Integer
Dim DA As New OleDb.OleDbDataAdapter(SQL, OLEDBCon)
Query = DA.Fill(DS)
DA = Nothing
End Function
Public Function Execute(ByVal SQL As String, ByVal OLEDBCon As OleDb.OleDbConnection) As Integer
Dim com As New OleDb.OleDbCommand(SQL, OLEDBCon)
com.ExecuteNonQuery()
com = Nothing
End Function
this is your connection string:
Dim con As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; " & _
"Data Source=sample.mdb")
code of your button save:
dim strInsert as string
try
strInsert="Insert into table1 (field1,fields2...) Values('" & txt1 & "','" & txt2 & "'...)"
con.open
Execute(strInsert,con)
MsgBox("Record Saved")
con.close
end try
my code is simple.

You can't really intercept them without writing your own packet sniffer ad reassembling the traffic yourself.
The other way to do it is to stop the Messenger service that comes with Windows and write your own replacement for it, taking over the TCP/IP port that it normally listens to.

You do know that explorer.exe is the process that give you your desktop, right? Why would you want to stop that?

Hi,
I am trying to execute the the function "RegSetKeySecurity" from advapi32.dll in VB Script.
for creating the object i am using wshAPIToolkitObject but i am getting the error...
"WScript.CreateObject: Could not locate automation class named "wshAPIToolkitObject.ucATO"
code :
Set oATO = WScript.CreateObject("wshAPIToolkitObject.ucATO")
lResult = oATO.CallAPI("advapi32.dll", "RegSetKeySecurity", hKey, SecurityInformation, pSecurityDescriptor )
please help me...do i need to have some dlls ?
or i need to register some dlls ?

It would appear that you either don't have this library installed (it's not part of Windows) or you do have it and it's not registered properly (use REGSVR32).

can anyone tell me how to connect to an access database and then add a feild to that database.
any help with this would be greatly appreciated as i literally don't have a clue how to do it.

what are you using ? adodb ? adodc ?
adding field/column ? why dont you make it directly in access ? or did you mean insert value of your table's fields ?
you can use sql - INSERT command to insert value of fields
and ALTER for add and drop column...
if you're using adodb.. here is the connect function
<br />
Function connect() As Boolean<br />
Dim strConnect As String<br />
connect = False<br />
On Error GoTo errHandler<br />
strConnect = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\dbpakar.mdb;"<br />
Set conn = New ADODB.Connection<br />
With conn<br />
.CursorLocation = adUseClient<br />
.Open strConnect<br />
End With<br />
connect = True<br />
Exit Function<br />
errHandler: Debug.Print "ERROR! error number: " & Err.Number & ", Description: " & Err.Description<br />
End Function<br />
dont forget to declare the conn , e.g
<br />
Public connVP As ADODB.Connection<br />
if you're using adodc, then just set the adodc's property.
sorry if this isn't the answer that you're looking for- i misunderstood it then..
