I tried to create textbox at run time depending on the value input by the user. I used a for loop to effect the creation but when I run the code only the one textbox is displayed.Please how do I ensure that all textboxes are displayed and the form expands proportionally.
The code is here below:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim x As Integer, b As Integer
If (IsNumeric(txtdata_num.Text)) Then
x = CInt(txtdata_num.Text)
Dim st As New System.Windows.Forms.TextBox()
For b = 0 To x - 1
st.Location = y
st.Name = "textboxA"
st.Size = New System.Drawing.Size(40, 10)
st.Visible = True
Me.Controls.Add(st)
y = New System.Drawing.Point(st.Location.X + st.Size.Width + 10, st.Location.Y + st.Size.Height + 10)
MsgBox("my name is " & st.Name)
MsgBox("my locattion" & st.Location.Y & st.Location.X)
MsgBox("my width" & st.Size.Width & st.Size.Height)
Next
End If

Dim x As New TextBox
x.Location = New Point(20, 350)
x.Size = New Size(100, 20)
x.Name = "a"
Me.Controls.Add(x)
Dim y As New TextBox
y.Location = New Point(120, 350)
y.Size = New Size(100, 20)
y.Name = "a"
Me.Controls.Add(y)
its worked whatever the name is , the two testboxes have the same name

hi
if the column department defined as string then the syntax is
("department = 'igls' ") you must put the single quote around the string

HOw can i print preview of print my text file in vb.net?
Thanks
................

More info-- are you trying to open a text file then print it out to a printer. If so
you could just print it to a text box and use the printpreviewdialog control.
depending on the file size you may want to use a stream reader to populate a listbox line by line. Then print each line to the the print document.

Can u give me an example?
Thanks
