I'd like to make a textbox that accepts only numbers, but not integer, but rather double.I've read here about e.Handled = Not Char.IsDigit(e.KeyChar) and it works, but again, it can be used only for integer, since it declines decimal point.Another thing I've read here is If Not Double.TryParse(TextBox2.Text, value) Then .... and it would work fine, except that it allows only decimal comma instead of point.

I am writing a math game for my brother in Visual Basic to help him with double digit numbers(both adding and subtracting).Normally you solve a problem by writing right to left on a piece of paper. Is there any way of setting the text box to do this?
For Example:
58
+ 18
You would type in the text box '6' followed by '7' so it would read '76'I set the right to left property but it does not do what I want it to do.
found that Visual studio Basis not have a 'Package and Deployment' project type, andVisual studio professional Trial Edition is a temporary solution and also I remember that the license agreement says that Trail Editions

View 1 RepliesI would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

View 1 RepliesI want to programmatically set the focus to the last row (bottommost, its only one column wide) in the DataGridView control for Visual Basic. How can I do so?
So far, I have tried DGV.Rows.GetLastRow(DataGridViewElementStates.Selected)
without success, though I did not expect that to work. It absolutely must select that last cell. Otherwise, the application is nearly impossible to use!
Here is a screenshot of what I am making with this: [URL]..The "Paste Clipboard Contents" button only pastes into the selected cell, though I guess I could find a workaround.
I am working on an assignment, so need to pass the file to the instructor. I thought I remembered a way to input a placeholder character(s) that tells the computer that the path is flexible until the point where I declare the actual path.
For example: if the directory is C:documentsMyProjectinDebug on my machine, and is F:usersownerclass assignmentscis101StudentAMyProjectinDebug on the instructor's machine, can I put a "wildcard" type of character that points to the ...MyProjectinDebug file that will work on both machines in the Initial Directory property?

I am looking for special tag codes that can be used to define certain words in a diffierent font format, like bold, italic, etc. I have a special command that accepts initial tag and end tag to these special words.So, these tags must be interpreted by textbox in VB to turn some words in bold, for instance, and change back to normal font after those words.
The command I have is:
textbox.text = data_base_name.FieldByName("field_name").HighlightedString(index as long, start_tag as string, end_tag as string)
The effect in the textbox should be like this:
Example of special word in bold.Any one knows about the existance of these special tag codes? I wonder if there is something like old DOS Codes, or ANSI, that can be recognized in VB textboxes.
In a label box, I want to list a couple of websites, email address along with some text. How do I go about it?
Potential uses- As a Help > About dialog box where websites, email of the author can be listed.
To make things as easy as possible for the user, and encourage visiting of the mentioned websites.
Simple text will be ignored, while standard blue color, underlined text with hand mouse-cursor will need no thinking on user's part.
The idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.
View 1 RepliesThe title pretty much precisely asks the question, but I shall repeat;
When I double click on a form control while in the design view in a Web Application project within Visual Studio 2010, say a 'button' or a 'submit' for example, it inserts a javascript function into my .aspx file. When I do this at work it automatically creates an event handler for the control in the code-behind.How do I change this to that setting? I have used '/resetsettings' already, and other answers to similar questions do not solve my problem. I have reinstalled, gone through every menu I can find (though I may have missed something)I don't want to type those event handler subroutines every time!
