I'm trying to create a backspace button. For it, I have:
If Len(TextBox1.Text) > 0 Then
TextBox1.Text = Left(TextBox1.Text, Len(TextBox1.Text) - 1)
End If
I get the error: 'Public Property Left As Integer' has no parameters and its return type cannot be indexed.How do I, first off, solve the error, and then, make it functional?

My program consists of a TextBox and a Submit Button. When I press the submit button, the entry in the Textbox will be copied to the active window (notepad for example).I would like to let my program executes the "Submit Button" when I'm already on notepad. So I do not need to switch to my program to Press the Button, but instead, when pressing the BackSpace button on notepad, the submit button of my program will be executed.I hope I gave enough details, I do really need to know how to do that.By the way, I heard that we can load the content to cach or something like that, i did not really get the point... But maybe "cach" and "load" will give you more ideas...

View 4 RepliesI have 3 text boxes that update with each other. One the user inputs the text, two the text is used for translation and instantly deleted, and three displays the translated text. If I need to backspace the code updates the translation adding double of each letter I delete. I need a way to skip all of the application code every time the backspace key is held. My current code here (full dictionary cut to save space).

Suppose I have a Microsoft Expression Blend. Is it possible to create a custom control (such as a button) in MSE Blend and then import it to visual basic 2010?For example, I want to create a custom shape button (different from what is available in the toolbox in VB2010) (like for example a pen-shaped button) in MSE Blend. Can I import it to VB2010 to be used with Windows Forms Projects? If yes, how?

1. Something similarly I want with another button - when I click button2, I want to remove specific object - let say panel2, not hide it.
2. The second thing is that I want to put text from my textbox into excel, but in specific row. I would like to do that with word file as well. I would like to put text form my textbox in specific table, or row, or line. I only know to put text into a file.

View 4 RepliesI'm writing an in-house intranet application in ASP.NET and VB.NET. My 'customers' are beginner to medium-level users. All of our browsers are IE8 and above, standard.The application works great, except for one thing. The backspace key. When a user types an invalid number into a textbox, a RegularExpressionValidator and ValidatorCalloutExtender fire off and notify the user. Perfect. Except that, when the user closes the popup warning and notices the cursor is still flashing in the textbox, he/she feels it's time to hit the backspace key and delete that pesky field value.
Unfortunately, the browser interprets this action as a desire to go 'back' into the page history. My boss is screaming. His bosses are screaming. I have a headache.So, how can I turn off this behavior? I still need the backspace to eliminate characters in the textbox, but nothing else. Company policy here: Backspace is to delete characters from the screen. Nothing more, nothing less.
can i disable backspace in my keyboard in vb 2005.

View 3 RepliesIs there any way to exchange backspace with delete key. I hav used this code in key_down event of rtb
if e.KeyCode = Keys.Back then
SendKeys.Send ("{DELETE}")
endif
but now it works as both backspace and delete.
You need to test for the backspace character, and if it's there, fix up the input.Maybe something like this:
If Right$(TxtQP.Text, 1) = vbBs Then
TxtQP = Left$(TxtQP, len(TxtQP)-1)
End If
Or is the backspace not showing up in the string, but as the input character kicking off your procedure?
Below is the code I am using to restrict user from entering any other characters except for the predefined ones. But using my code I cannot hit backspace.
How to include backspace also ?
Dim s As String = "0123456789$"
If s.IndexOf(e.KeyChar) = -1 Then
e.Handled = True
End If

View 1 RepliesI have built an addin for outlook that has a usercontrol shimmed into the interface. Everything works wonderfully EXCEPT for one textbox on one subpanel of the control. I have tried everything I can think of, but have not been able to resolve the issue:
The textbox *(A regular System.Windows.Forms.Textbox) functions as you would expect in any application with one exception. It will NOT accept the backspace key. So much so that the KeyDown, KeyPress, KeyUp events will not even fire when I press the backspace key. There does not seem to be any parameter suppressing it, and the control has focus. What is even stranger is that it works completely fine if you hold down the shift key while pressing the backspace key.

I am busy with a Windows Forms application.The purpose of the application is to convert Excel documents to HTML format so that they can be published to a website.I have most of the code finished and the application is looking really good.I have although encountered a problem. On the Form I have created an Export, File and Edit button.With the edit button I would like the user to be able to select whether they would like to save the 1st,2nd,3rd sheet and so forth.
I would like to create a window/Form within the edit button that would say something like "select excel sheet" along with a save button where the required sheet number could be saved or selected as a standard save procedure everytime.I know that I need to do this with the settings.settings control. I have tried numerous ideas up until now but it continues to baffle me.
