I'm having some trouble getting my button to erase the text that is in the textboxes when I hit it. I thought it would be something like txtAnswerText.Text = "" in side of the Next1_Click sub but that didn't do anything at all.

View 2 RepliesI am confused about how to make a button able to clear the text in all textboxes. I know in c# I can just say textbox1.Clear(); but this won't work in this case.

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

[URL]...In this program, you need to insert two Textboxes, four labels and one button. Click the button and key in the code as shown below. Note how the various arithmetic operators are being used. When you run the program, it will perform the four basic arithmetic operations and display the results on the four labels.Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

View 14 RepliesI dynamically create buttons on a form and use the button text as ids so that I can pass that to an SQL query to pull saved data about that button when necessary, but I also use an image over buttons that have information saved about them. What I need to know is how do I keep the text on the button from appearing when there is an image assigned to that button? By default vb.net shows both the text and the image and no TextImageRelation values allow for the image to take precedence. I tried changing the text color to transparent, but the outline of the text is still visible through the image. Is there anyway to keep the text value as it is but just show the image on the button?

I would like to create a button that clears textboxes and comboboxes when it is clicked. For example when 'btnClear' is clicked then txtDate gets cleared (i.e. txtDate is 22/05/2000 then when btnClear is clicked it has nothing in it)
I have already tried
txtDate = ""
and
txtDate = Nothing
but an error comes up.
I created a form with 2 labels 2 textboxes and a button. Basically it is a login from. When I launch the form it shows the blinking cursor in the 1st textbox(this is ok) but when i try to type nothing happens. Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.
View 12 RepliesI have started learning a bit about programming. "Create a new project, and add two text boxes and a button to the form. Write code that, when a button is clicked, places the text in the first text box into the second text box. Hint: Use the Text property of the TextBox controls." Now I am trying to look at it logically do I put the same text in both textbox properties and write code that says if it is visible in one it cant be in the other or declare the text in the code, either way I am a bit stumped, but feel if a stick with it it will click and i will be writing my own code in no time.
View 8 RepliesI am trying to save new data every time and then I have to edit it or load it. here is a screenshot you might get some idea by looking at this:
First I will input data (in all textboxes) using create button which will be stored then If I want to edit any thing I will input only the part number and press search. the stored data will come up. I will edit it and update it (Load button is update). Now I can save it in txt file and load it using regex but the problem is edit. I can not edit. If i create a database I cannot save 100 parts (or may be more) in one database so it might create too many db files. So is there any other option I can save parts detail then load it and edit it without create so many dbs?
this application I'm writing is for Employee Data. I have 7 texboxes and 1 combo box.With the file menu I have used that function to save info inputed in one texbox. However for this application I need to use btnSave button to save the record.

How can I implement this with a button?
I have to make a calculator for school but I'm in a big dilemma. :( The thing is, I have this calculator with three textboxes and of course digits and operators. There's two input textboxes, txtInput1 and txtInput2 and then there's the buttons from btnZero to btnNine. My operator buttons automatically do the calculation and the output comes in txtDisplay which is disabled (so that you can't write in it).
And the problem is here, I want my btnZero to btnNine move their textvalue to my txtInput1 and txtInput2 as long as they are selected (so the cursor is blinking in it). Now I use "txtInput1 = txtInput1.text & btnZero.text" sure that works, but only for one txtInput. If I can't solve this I'd have to make all the buttons twice. ;( (Edit: If I press my operator button then "txtDisplay.text = (txtInput1 "operator" txtInput2)")
I have two forms in my project, Form1 and Form2. In Form1 there is one TextBox called Text1, and in the Form2 there is TextBox called Text2. I have one button in Form1, called Button1. When I click on Button1 I want that Form2 open and in Text2 is text from Text1.
Code for Button1:
Me.Hide
Form2.Show
Form2_Shown:
Text2.Text = Form1.Text1.Text
And Form2 open but in Text2 there is no text.

Basically I have an application that has 2 textboxes and a button. What I am trying to do is when the button is clicked, it takes an entered string from box one (which is validated to only accept numbers) adds 235 to it then converts it to hex and finally reverse the string and sets textbox two equal to that value. Note that the final string has to be eight digits so the string may needed to be padded with zeros before the string is reversed. With that said how could I go about doing this? Also I do plan to add 2 more textboxes and another button to undo this process but I am thinking if I can figure out do it one way writing the code to undo the process shouldn't be too hard.

View 8 RepliesI was looking for some better way of coding to populate all text boxes and make them visible once a button is clicked. I have a letter like format on a page with labels displaying address, name etc and it was recommended that on this page some of the information should be able to be edited. The idea I had was to keep the labels displaying the information but then when the edit details button is clicked the labels disappear, text boxes will appear and be populated with the same text as the label to allow the user to edit the details.
I seem to repeating lines of code but changing one thing each time on page load
Dim Sname As String = Request.QueryString("Name")
lblStuName.Text = Sname
tbStuName.Text = Sname
tbStuName.visible=false
[Code] .....
On edit button
tbStuName.visible=true
tbAddress.visible = true
etc..
On the save button
sqlStatement = "UPDATE StuTable SET Name = '" & lblStuName.Text & "', Address = '" & lblAddress.Text
My code seems very repetitive in many parts, I was looking for a better coding style to do this.
