A label does not have a MaxLength Property, but it would probably be safe assumtion that it's a 32bit integer number. So a label would have 2^32 maximum characters. (4294967296 possible characters) **EDIT** [Here](http://vbcity.com/forums/t/76219.aspx) is a link that leads to an article with a custom marquee control.

Talk about bringing back dead threads... You have less or to many columns in your insert. If less on purpose, you will have to set the values to their columns. Example: Dim sqls As String = "INSERT INTO table (column1, column3, column4) VALUES ('val1','val2,'val3')

You can try py2exe and call the exe from the vb.net application. Example: Process.Start("pathToMy.exe")

You can try something like this: For i = 0 To ComboBox1.Items.Count - 1 e.Graphics.DrawString(ComboBox1.Items(i), PrintFont, Brushes.Black, horizontalPrintPosition, verticalPrintPosition) 'Leave some space for the next item. verticalPrintPosition += 5 Next

Are you posting a code contribution, or requesting help? If you are requesting help, it might be wise to ask a question when you post. =)

I have searched for a distributable for the same purpose... It came down to installing CR on the machine.

Though a little high in cholesterol, shrimp are a great source of protein with low calories. Grilled/Steamed shrimp (3oz) can net about 85 calories with 18g of protein, but with 120mg of cholesterol.

You can split the contents of the textbox, storing them in list (of string) and remove the element, then rebuild the string. Example: Dim str As New List(Of String) 'Assuming you are using a , seperator. str = TextBox1.Text.Split(",").ToList str.Remove("test") For i = 0 To str.Count - 1 If i …

Try something like this: For Each lviItem As ListViewItem In ListView1.Items If lviItem.Text = ComboBox1.Text Then TextBox1.Text = lviItem.SubItems(0).Text TextBox2.Text = lviItem.SubItems(1).Text End If Next

Something like this would do the trick: "INSERT INTO destinationTable(Itemname,Itemcode)" & _ "SELECT sourceTable.ItemName, sourceTable.ItemCode " & _ "FROM sourcetable WHERE sourcetable.Column=Value"

Try something like this: Dim lviNew As New ListViewItem With lviNew 'NOTE: ' I always assign my unique values to the .Text property. ' This will make it easier to compare against a database. .Text = TextBox1.Text .SubItems.Add(ComboBox1.Text) End With

I am not seeing a handler for the form close event, is something firing off - or is it not being handled? As for currency, try this: txtPrice.Text = CDec(txtPrice.Text).ToString("C") As for the navigation, are you scrolling, or clicking to the next entry?

Does your report cycle through the listview's items? If so, just execute the report on the listview's selcted items. Example: For Each itm as ListViewItem in ListView1.SelectedItems 'Do Work Next

After looking at your code, I do not think that you are receiving this error from this chunk of code. **Possibility** One of your substrings from the listviewitem is a string where you are trying to store Quantity. Can you please give an example of your data. OR Can you …

If the quantity is an auto number, it will not be changeable. Other than that, just wrap your values that are strings in the correct casts or 's. Example: 'If quant is an int the listview try Cint(Me.ListView1.Items(0).SubItems(3).Text) 'Or OleDa.UpdateCommand.Parameters.Add("UPDATE [Inventry] SET [QTY] = [QTY] - '" & Me.ListView1.Items(0).SubItems(3).Text & …
