On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If

View 15 RepliesHello,
So I'm trying to create a function that will remove certain characters (defined by me and may be subject to change later) from a string leaving only numbers. Reason-being is I have some textboxes that I format as phone, SSN, and accounts numbers based on string length, and when I click or tab back into the textbox I need to make sure those formatting characters get removed so when I re-exit the textbox the proper formatting takes place. I am able to accomplish it by calling CleanUp(), below,
Public Sub CleanUp()
TextBox1.Text = TextBox1.Text.Replace(")", "")
TextBox1.Text = TextBox1.Text.Replace("(", "")
TextBox1.Text = TextBox1.Text.Replace("-", "")
TextBox1.Text = TextBox1.Text.Replace(" ", "")
TextBox1.Text = TextBox1.Text.Replace("$", "")
End Sub
but the problem I have it this obviously only works for Textbox1, not any textbox I want to apply it to. I want to be able to call CleanUp() from textbox1.gotfocus, textbox2.gotfocus, textbox3.gotfocus, etc... .
I've tried
Dim Box as Textbox = Textbox.text
Box = Box.Replace(")", "")
Box = Box.Replace("(", "")
Box = Box.Replace("-", "")
Box = Box.Replace(" ", "")
Box = Box.Replace("$", "")
but get the error "Reference to a non-shared member requires an object reference" (blue squiggly under "Textbox.Text" (VB 2010 Express) which I can't seem to find anything relevant to this by searching for that error.
Thanks for your help.

View 4 RepliesI have two tables that are related to each other in a 1-1 relationship (each row in the main table has exactly one corresponding row in the second table).I also have a winform in which I'd like to show the main table in a datagridview, and for each row selected in the grid to show the fields of the corresponding row of the second table in various textboxes below the grid.

I've got a micro controller with 4 channel ADC that I want to make a program for. It will be for data logging. I want to take each channel and display it in 4 textboxes to begin with.Later I like to do some conversions of the data to show temperature , use a lookup table and a few other things in each of these boxes, but at first I'd just like to concentrate on getting the data split into each box.The chip output is 8 bytes . The first two are the channel select and the next two is the data. Output of the chip is in ASCII. I don't want to send to the chip, just receive.If I view the output in decimal I get 1xx 2xx 3xx 4xx (xx being the data to display).
