As the others said. Furthermore having progBar.Increment(1) execute for every item is another waste: if you hope your app to handle 190,000 items in say 19 seconds, then you are updating the progress bar every 100 microseconds, you would need bionic eyes to see all these updates (assuming infinite resolution for your display).
I suggest you let the progress bar work at 1/1000 of the current setting, so reduce its Maximum by 1000 and call its Increment() only once every 1000 items handled.

The progress bar was actually just so I could see that the thing was working at all. It'll eventually be either removed or as you say, have it's increments drastically reduced. The latter is the most likely.
Even with the progBar incrementing every list item, the app now runs through 150,000 items in about 30 seconds - instead of 3 or 4 minutes. Ultimately, the app will be pulling data from about a dozen lists, most with less than 30,000 entries and some with only a couple hundred. There will be only two or three "giant" lists. But I didn't want it to take all day when using them.
Thanks!

Hi.
I have got a DLL with from one of our software providors that queries a particular info from an IP. This code has been written in c++, and i like to call the function from VB.
I have registered the DLL with regsvr32.
I have created a new vb project, and added reference to the COM object ( found afer i registered it)
The referenced DLL are now found in object browser named "PrinterAccessLib"
The class i would like to use is named CONFIG
When i look in the object browser, i can see the function GetStatus like this:
Sub GetStatus(ByVal P_szIpAddress As String, ByRef P_szBuffer As String)
To me is looks like the sub should update the variable status, but when the sub has been called, it is still ""
I do not get any errors, and i can see with a network sniffer that the DLL comunicates with the printer.
What am i doing wrong ?
Here is the code using the dll sub:
Public Sub Main()
Dim status As String = ""
Dim ip As String = "155.209.118.123"
Dim ObjPrinterStatus As New PrinterAccessLib.CONFIG
ObjPrinterStatus.GetStatus(ip, status)
Console.WriteLine(status)
End Sub
Thanks
Best regards
Bjorn.

A COM object is a black box. If there's a method and you're calling it, we can't help you any further, you need to talk to the vendors of the dll to find out why it's not responding to your call in the manner you expect.

This is no way a beginner's job.
AFAIK you will need to use P/Invoke win32 api for this.

Hi,
I have a Treeview with 3 nodes under the root. My aim is to check the 2nd node whenever any child nodes under 2nd node gets checked. How could you do that?
Thanks.
What a curious mind needs to discover knowledge is noting else than a pin-hole.
|
|
|
|
|
There's an event that gets fired when the node is checked. Loop back through the .Parent property until you reach the node at the second level, and check it

use BeforeCheck or AfterCheck event

Hello all
I'm trying to include the a Grammer check into my app; one of the approaches that I've come across is using MS.Words' but it seem that I'm facing somedefficulties that I can't figure out;
mports System.Runtime.InteropServices
Public Class Form1
Inherits System.Windows.Forms.Form
' Invokes either the spell or grammar checker.
Private Sub SpellOrGrammarCheck(ByVal blnSpellOnly As Boolean)
Try
' Create Word and temporary document objects.
Dim objWord As Object
Dim objTempDoc As Object
' Declare an IDataObject to hold the data returned from the
' clipboard.
Dim iData As IDataObject
' If there is no data to spell check, then exit sub here.
If TextBox1.Text = "" Then
Exit Sub
End If
objWord = New Word.Application() // My problem is here as it shows that it is not defined
objTempDoc = objWord.Documents.Add
objWord.Visible = False
' Position Word off the screen...this keeps Word invisible
' throughout.
objWord.WindowState = 0
objWord.Top = -3000
' Copy the contents of the textbox to the clipboard
Clipboard.SetDataObject(TextBox1.Text)
' With the temporary document, perform either a spell check or a
' complete
' grammar check, based on user selection.
With objTempDoc
.Content.Paste()
.Activate()
If blnSpellOnly Then
.CheckSpelling()
Else
.CheckGrammar()
End If
' After user has made changes, use the clipboard to
' transfer the contents back to the text box
.Content.Copy()
iData = Clipboard.GetDataObject
If iData.GetDataPresent(DataFormats.Text) Then
TextBox1.Text = CType(iData.GetData(DataFormats.Text), _
String)
End If
.Saved = True
.Close()
End With
objWord.Quit()
MessageBox.Show("The spelling check is complete.", _
"Spell Checker", MessageBoxButtons.OK, _
MessageBoxIcon.Information)
' Microsoft Word must be installed.
Catch COMExcep As COMException
MessageBox.Show( _
"Microsoft Word must be installed for Spell/Grammar Check " _
& "to run.", "Spell Checker")
Catch Excep As Exception
MessageBox.Show("An error has occured.", "Spell Checker")
End Try
End Sub
Private Sub btnSpellCheck_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnSpellCheck.Click
SpellOrGrammarCheck(True)
End Sub
Private Sub btnGrammarCheck_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnGrammarCheck.Click
SpellOrGrammarCheck(False)
End Sub

Are you getting any error message?
I guess you need to use fully qualified names.
जय हिंद

|

Yes it is an error message ...
|
|
|
|

You need to specify the fully qualified name as I had mentioned before ie use
Microsoft.Office.Interop.Word.Application .

I've done what you have mentioned; I appreciate your help...and now it says on the error message "Error Expected" what does it mean?

When I start my program, it gives me error on this line.
.SubItems.Add(MyDataReader("A2".ToString))
"Overload resolution failed because no Public "add" can be called with these arguments"
Don't know what hte problem is........
Here are the code
Public Function FillListBox(ByVal Sqlstring As String)
ListBox1.Items.Clear()
ListView1.Items.Clear()
Dim OleDbConn As OleDbConnection = New OleDbConnection(ConnString)
OleDbConn.Open()

Dim MyDataSet As DataSet = New DataSet()
Dim MyOleDataAdapter As OleDbDataAdapter = New OleDbDataAdapter()
MyOleDataAdapter.SelectCommand = New OleDbCommand(Sqlstring, OleDbConn)
MyOleDataAdapter.Fill(MyDataSet)
MyOleDbCommand.Connection = (OleDbConn)
MyOleDbCommand.CommandText = Sqlstring
MyDataReader = MyOleDbCommand.ExecuteReader
Do While MyDataReader.Read
ListBox1.Items.Add(MyDataReader("Luidraad"))
Dim MyItem = ListView1.Items.Add(MyDataReader("luidraad".ToString))
With MyItem
.SubItems.Add(MyDataReader("A1".ToString))
.SubItems.Add(MyDataReader("A2".ToString))
.SubItems.Add(MyDataReader("A2".ToString))
