There is a much faster way to get data into an Excel file using the Excel range and an array. You can build an array easily from a datatable Dim _r As Integer = _tbl.Rows.Count Dim _c As Integer = _tbl.Columns.Count Dim _arr(_r, _c) As String 'add header For i As Integer = 0 To _c - 1...

Not sure why you would want to do it, but try this: For Each c As Control In MyBase.Controls If c.GetType() Is GetType(VScrollBar) Or c.GetType() Is GetType(HScrollBar) Then c.Visible = False End If Next c This assumes that you are extending the DataGrid as an inherited control...

You can probably get what you need using the ComboBox.KeyUp event or similar.

Try searching for Threads about DataGridViewCheckBoxColumn and DataGridViewButtonColumn. I'm sure this has come up before, but it's not something I'm familiar with. Glad to be of help with the first bit.

OK, I decided to completely re-read everything you've posted - realised that you just want to dump an array into a textbox - adapted your Sub Private Sub PrintArray() Dim str As String = "" Dim r, c Dim character As Char For r = 0 To 23 For c = 0 To 79 str += vt100(r, c) Next...

If you try Textbox1.text.insert(1,"foobar") when text = "" then you will get an out of range error as there is no chr in position 1. The StartIndex is zero-based, so to insert text at the start use Insert(0,"foobar") I think you are getting confused with the height and width properties. The...

Do you know where to find the .exe that your project has created? This is saved as ...ProjectFolder\bin\Project.exe For example if my projectfolder is C:\myCalculator\ The executable file will be C:\myCalculator\bin\myCalculator.exe You should be able to add a shortcut to this file to your...

What are you actually trying to do? There may be a simpler solution than refering to this hidden control directly.

You could set the datasource to a dataview and set the .Table property to your DataTable dim myDataView as New DataView myDataView.Table = myTable myDataView.Sort = "" myDataGrid.DataSource = myDataView myDataGrid.Refresh Personally, I would put this in place as a quick fix and then work on a...

Oops - should have read TextBox1.Text.Insert...

I think I see where you are going wrong. If you want to insert text ie. data(i) in a certain position in the text use TextBox1.Insert(StartIndex, Value) The Selection... properties are more for the GUI so that the next keyed or pasted text will replace the selection.

Try RichTextBox.SelectionStart = 0 You may also need to set SelectionLength to zero if you want to insert text rather than replace the selected text

Glad to help - this is a pattern that you will use a lot when working with collections: dim obj as new Object 'set some properties for obj Objects.Add(obj)

This approach should work... Dim node As New TreeNode(Str.Text) node.Tag = drData.item("Entry_Id") OpenNode.Nodes.Add(node)

Try over_Comp.GetUpperBound(0)
