I got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

2------Boris
3------Bill
Whien I enter "B" in text5 and run following codes then it show error message as IndexOutOfRangeException was unhandeledThere is no row at position 0I have two question
1) Why it does not select name begins with "B"
2) If it has no row then why it does not exit sub.
str = "select sno,name from employees "
str &= "where Name Like '" & (TextBox5.Text) & "%'"
cmd2 = New SqlClient.SqlCommand(str, con)

I basically made a listbox, a button, and a popup window. The button openes the popup window, in that window you type some text, press "OK" and the text gets added to a list box. Simple right? Guess not...-Textbox1 is the textbox in wich you input text.-Label1 is the label on the popup window that tells you what to do. It's text is either "Edit name:" or "Input name:"This is the function if you click "OK".
If Label1.Text = "Edit name:" And Textbox1.TextLenght > 0 Then
Form1.name_list.Items.Remove(Form1.name_list.SelectedItem)
Form1.name_list.Items.Add(ime_osebe.Text)
Else

My program reads a 3rd party data text file and I give the user the ability to add a row. The problem I am having is one users text file contains an extra tab at the end of each datarow thereby creating an extra column when i view it in DataGridView it gets labled "NoName"
Moving foward I get the following error upon trying to isnert a new datarow. The INSERT INTO statement contains the following unknown field name: 'NoName'. Make sure you have typed the name correctly, and try the operation again.

The above code stops running at the point of the da.fill line with the error that the specified table does not exist.In my limited knowledge so far to me it looks like the operators table exists as it showing in the Solution Explorer.
