Im trying to keep a running total within a text box. The code I am using is
RunningTotal.Text = Txtbox1.Text + RunningTotal.Text
WHen I do this, RunningTotal.text only adds the content from txtbox1 onto the end, so I end up with something like " 1.50, 1.50".
Every time I hit Add, i just get another 1.5o added onto the end of the existing 1.50, 1.50.
i am using vb.net 2005, in my window form i have textbox as txtbox1 and txtbox2. if i entered any text in txtbox1 and press my tab button the txtbox2 should display the same text as txtbox1 .
View 2 RepliesI am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.
I'm using Visual Basic 2005 Express Edition and I was just wondering if someone could help me out with a few things? I'm making a Notepad-type program just to clarify things.1. I have a button which adds text to my RichTextBox1 (excuse the name), but when you click it it adds text to the end of the script. I want to make it so the text is added where your "cursor" (the blinking thing which lets you know where you're typing) is, at the current part of RichTextBox1. At the moment I'm using:
RichTextBox1.Text = RichTextBox1.Text + "The text I'm adding" If anyone could tell me the code to make it put "The text I'm adding" at your current cursor that'd be great.
2. I have a Save As button and a Save button. When you click Save As and save the file it works 100%, when you click Save and you haven't saved previously then it works 100%, but after you have saved the file and then click save it doesn't overwrite the file. Here's the code for Save:
[code]...
So if anyone can tell me the code that's needed so it will overwrite the current file 3. I have a FontDialog but I have no idea what the code is supposed to be to make RichTextBox1's font change after you click Okay in the FontDialog.
How can I create a separate class that has the function that adds dynamic text box, so that I will just call that function to my main form. I have the code below that does add dynamic text box but it is already inside the button of my main

I have a Save() function as shown below;
Code:
Public Function Save() As Boolean
Dim valid As Boolean = True
Dim Message As String = String.Empty
[Code].....
What I want to do is when The toolbarbutton1 is clicked it checks for the
Save () - if txtprojend.Text = "" then it displays the message. So far, it does that but then it closes the form. I don't want it to close the form unless the user adds text in txtprojend, as it is a mandatory field.
Is there any way to make the AppendAllText so that it startes a new line before it adds the text?

View 3 Repliesis there any way to get a numberupdown text to show the value "+" so if the value is a positive number then it adds the plus sign in front of the digits.
example:
2.00 would become +2.00
3.25 would be +3.25
as when its negative its
-2.00
-3.25
It already adds the negative value when its negative of course.

I am trying to take the amount entered in a text box and save that to a sql database in decimal format. The field in the table is set as decimal 7,2

myCommand.Parameters.AddWithValue("customer_contribution", Convert.ToDecimal(CType(Me.FormView1.FindControl("CustomerContributionTextbox"), TextBox).Text))
I've also tried it without the Decimal conversion and end up with the same results.
myCommand.Parameters.AddWithValue("customer_contribution", customer_contribution)

View 7 RepliesI have created an app which will email text from a rich text box to the chosen email address.
obviously richtextbox.text however if the text in the rich text box is formatted (e.g a color) then obviously this doesn't sent as it is merely transferring the 'text'. Also if the rich text box has an image within it that will not send either.
How will I go about making it send everything within the rich text box via email?
