I am trying to show the square root of the number entered in the textbox. when the user presses Q (Uppercase), the square Root should be shown (in the textbox). I did manage to get the sqaure root, but the problem is that when I press Q the Letter Q is also typed in. For example, if I enter 25 in the textbox and press Q then I get Q5 as the result. Is there any work around to this problem ? Below is the code that I have used.
Private Sub Textbox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar = Chr(81) Then '81 for Letter Q
Dim root As Double = Math.Sqrt(Val(TextBox1.Text))

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

View 8 Repliesmy OCR copy text to a TextBox with at end, acts like enter key. Is it possible to replace it to something or remove it? For example, I want to copy number 1000 to my text box with OCR but I get 1000(its a little different boxes, I couldnt copy exact ones here). And I cant do
TextBox2.Text = TextBox2.Text.Replace("", "")
, because is an "enter key" and what I get looks like that:
I am trying to do this but it doesn't work:
VB
Dim str As String = "07" & GetBetween("Stephen 0761234567", "07", vbNewLine)Dim op As String = "lol" TextBox1.Text.Replace(str, op)
GetBetween is just a function to match something between something else. That works fine, the string (str) sets as 0761234567 just like I want but when i try to replace the text it doesn't work.

View 3 RepliesWhile my user is typing text into a textbox i want the characters " to be replaced with ' '. The thing is, when i put ' ' in the replace code, it thinks it is a comment so i cannot run the code without producing an error.Also in my multitext box, everytime i write text and hit ENTER, save and then load it back again, the last line ends with a comma, so:
Line 1
Line 2,
When the text is written to the file i read from, it will show like this:
"Line 1Line 2",
So i need a way of trimming ", when the apostrophe " and the comma , are together. My code already trims "".
Is it possible to replace string characters using the delimiter and limit of a split function?
For example you have this string "1,1,1,1,1"
I wish to replace sentence number 2 into the string "2" between the "," character so that will be limit number 1.
So the result would be "1,2,1,1,1".

View 3 RepliesI'm using the Oracle command dbms_output.get_line to retrieve output from a stored procedure. Once my code runs the command, I'm retrieving the results through a buffer string, 32000 bytes long.Inevitably, this string will have Oracle line breaks (chr(10) and chr(13)) in it that I'd like to replace with Environment.NewLine so I can display the output in a standard Winforms textbox.Here is the code I've been using - I don't recall exactly where I got the Oracle command right now, but if I find it, I'll add the link.
Dim cmdGetOutput As New OracleCommand("declare " & _
" l_line varchar2(255); " & _
" l_done number; " & _

This is one of those "seems obvious" as how to do, but came across interesting side effect in implementing. I'm trying to keep two text boxes syncronized when information is updated. In this example, I will be using txtStartDate and txtEndDate. If the txtStartDate is changed, then the txtEndDate should should be updated. Likewise, if the txtEndDate changes, I want the txtSartDate to be updated. The side effect I'm comming across is that when I set them up under the TextChanged event for both, the events seem to retrigger against each other indefinately (endless loop?). Am I using the wrong event? Is this a task for a delegate?
View 3 RepliesI'm using VB 2005 and MS Access 2000. I have a process that does some "stuff" with the data, re-queries the database, re-populates the form then displays a messagebox indicating that the process has completed. My issue is that after clicking OK in the messagebox, that whatever textbox the cursor was in prior to starting the process, now has all the text in it highlighted. If I don't show the messagebox then this doesn't happen. And if I don't call the process that repopulates the form controls, this doesn't happen. There's no code in the app that selects the contents of the textbox so is there a property somewhere that controls this?

View 4 RepliesEssentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
