Using an on-screen keypad

I am a complete newbie to programming and I need to work out how to use an on-screen keypad to enter values into a text-box. I'm not sure how to get the numbers to appear without erasing previously entered numbers. I know this is very basic but can anybody help?

Let's see the code your using. If your replacing everything in a TextBox when you hit a button, you're probably not assigning its Text property correctly.

I'd put this at an intermediate level task. On the surface, it looks really easy, but you have to have more than just a passing knowledge of how focus and selection works and how to track it properly.

If this input method was to be used in multiple places, it would be better written as it's own control.

This is not a good idea. The parent form should open all of it's child forms. Child forms should not be opening sibling child forms.

It can be done, but makes for spaghetti code:

Dim myForm As New Form3
myForm.MdiParent = Me.MdiParent
myForm.Show()

Hi
Move the cursor to the variable for which you are searching the declaration and then just press "F12" function key and you will be on the point where that variable is declared.

Export Datagrid to CSV

Hi All

The attached code fills a DataGrid for me from a CSV file. My App manipulates the data and represents it to the use. I then want to export to csv.

How is this done???

Private Sub FullImport(ByVal CommString As String, ByVal AnotherCommString As String)
Try
'Dim fi As New FileInfo(OpenFileDialog1.FileName)
Dim fi As New FileInfo(myFileName)
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Text;Data Source=" & fi.DirectoryName
Dim objConn As New OleDbConnection(sConnectionString)
objConn.Open()
Dim objCmdSelect As New OleDbCommand(CommString & "[" & fi.Name & "]" & AnotherCommString, objConn)
Dim objAdapter1 As New OleDbDataAdapter
objAdapter1.SelectCommand = objCmdSelect

objAdapter1.Fill(objDataset1, "Import")
DataGrid1.DataSource = objDataset1.Tables(0).DefaultView
objConn.Close()
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try
End Sub

When people make you see red, be thankful your not colour blind.

how to make label visible at runtime ?

hello I laid out on my form two labels which post the contents of my variables (just to help me debugging). I would like to reveal or to hide those labels using a combination from keys (like : ctrl + HDE) while the application runs. Do you know a way for doing this?

First step is to set the forms KeyPreview property to True. Then, handle the keypress event with something like this:

Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyPress<br />
    If e.KeyChar.Equals(Chr(8)) Then 'press Ctrl H<br />
        Label1.Visible = False<br />
        e.Handled = True<br />
    ElseIf e.KeyChar.Equals(Chr(21)) Then  'press Ctrl U<br />
        Label1.Visible = True<br />
        e.Handled = True<br />
    End If<br />
End Sub

This code will hide the label with Ctrl H, and show the label with Ctrl U.

Roy.

well, i'm not sure abt what are you asking abt but if i understood you , i think you want to use shotcuts to show or to hide labels

well , this is a event named "keydown"
i will write some thing here but this is not the right code cuz i don't remember all
this methode accepts two parametrs the first code : is to recuperate the ascii code of the button you taped at

& shift do the same thing but just for Ctrl & shift

you can know the ascii code of the button you taped by showing the parametre code in a textbox

private sub form_keydown(code ,shift)
textbox1.text = code
end sub
when you know it just change the code in the methode

private sub form_keydown(code ,shift)
if code = .... and shift = .... then
label1.text = ....
end if
end sub
end sub

it is hard to explain just in the furom
i hope you understood ma english Poke tongue | ;-P

ciao

try to be good if you can't be the best
