View 4 RepliesI'm building a program in which it asks for your name and age and determines a ticket price based upon these details. I want it to show the person's name, then their age, (jump down a line) then their ticket price, and then it jumps down a line to show the next person's name, age and ticket price. Issue is, when it's meant to jump down to show the next person, it just completely deletes the last person's details.I'm using this line of code:
TxtFareShow.Text = (Name & Age & vbCrLf & Price) & vbCrLf
How do I fix this?

I have a bit of a dilemma - in the ComboBoxColumn, I have added various numbers from 0 to 11. I need people to be able to type into the ComboBoxes in that column if the Combobox doesn't contain a value they need.I realise that I have to change the ComboBoxStyle to DropDown but am not sure how to. Also, for each row in the ComboBox, I believe I have to add the item that the user typed to the ComboBox list items for it to save but am also unsure how to do it.

View 3 RepliesI'm trying to create a text box that sends information to the registry. As an example, the user types "Value1" into the text box, and presses OK. The value in the text box (aka "Value1") goes to:
My.Computer.Registry.SetValue("HKEY_CURRENT_USER\TestKey",
"TestKey", "Value1")
I have a simple in VB/ASP.NET form containing two text boxes, I am attempting to apply some validation to the first text box using JavaScript. This is the first time I have attempted this and am having some trouble.I have a label beside the text box stating an error, this labels visibility property is set to False. I wish the labels visibility to turn true if the text box is empty when the user loses focus.For this I have used the onBlur option within the tags of the text box. It then calls the JavaScript function and should set the label to Visible but it does not. I have tested to see if it is entering the function by using an alert instead and that works. The problem seems to be trying to alter the visibility property of the label.
Here is the portion of my code:
The JavaScript:
function myRegEx(frm) {
if ( boxUsername.value == "" ) {
invalidUser.visible = True;

how to edit a text file that I have placed in a folder inside my application. The path to the file is "G:MyStuffEvolution_ Data_Extraction_v1Text Filess.txt" and I use a StreamReader to edit the file. However, once the file is edited, if I open the file in Microsoft Visual Studio 2010, the file is empty. Can anyone tell me how I can change? I also fear that once the application is deployed, the file path will no longer work as it will no longer be on my G: directory.Help Is A Click Away - http:[URL].....
View 6 RepliesI have a file in a certain place. I'm making a script with a button in it. For understanding. Let's say the text file has this written in it:
"ABC"
in it, How would I make it if I pushed one of the buttons, it would change that "ABC" to:
"CBA" ' Or anything else random "BCA", "CAB", etc.
and then save it?note I am using Microsoft Visual Studio 2010 so no VB v6.0?

I want to add nodes that behave in a similar fashion as when you add new folders in windows explorer. i.e. right click > new folder > then the new folder is added and highlighted as New Folder so that as soon as the user types they are overwriting the folder name.
I can add a new node as a child node of the node I have selected and label it "New Node" but I can't figure out how to select the new node and have it highlighted so that when the user types, they are overwriting the "New Node" text.
I have tried this but it doesn't work.
Private Sub AddProjectToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddProjectToolStripMenuItem.Click
Me.trvProjects.SelectedNode.Nodes.Add("New Node")
Me.trvProjects.SelectedNode = trvProjects.Nodes("New Node")
Me.trvProjects.Focus()
End Sub
I have a text file called: list.txt This is a list with all kind of lines like this:
14II_ARM_S_CLO_CLO_CLOVERIDS_PROPITEM_TXT_01194611IK1_ARMORIK2_CLOTHIK3_CLOAK=TRUE==200050000====PARTS_CLOAK=1==11=1===11_NONE Ofcourse every line has different numbers and letters.
The complicated bit is this:
I want to let Button1 check whats in TextBox1.Text and search "list.txt" for it. When it has got a match (there is only ONE of these numbers in list.txt).For example TextBox1.Text = "IDS_PROPITEM_TXT_011946". And I search for that so I find the line above. Now I want 3 other textboxes which show the 21st, 22nd, 23rd column/number after "IDS_PROPITEM_TXT_011946". And they should be editable by changing those 3 textboxes and clicking the apply button.How can I best do this, and please give a little example.
I have two text files, first text file looks as follows
File1
String1 String
String2 String
String5 String
String8 String
These fields match some of the fields in my File2, but here there is an extra column which shows a numeric field for that row.

I have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.
What I have so far:
If Val(txtEntered.Text) < 0 Or
(IsNumeric(txtEntered.Text) = False) Then
MsgBox("Sorry, but letters are not allowed!")

I'm new here and I'm trying to make a little program with Visual Basic (2010 Express Edition).The purpose of this program is:
1) Load the text file lines and split them into a constant and a value
2) Edit the text file lines values
The content of the text file is like this:
[Code]...
This basically split every lines in two parts: the constant ("Name", "Surname", "Age", "Hair") and the values ("Mario", "Rossi", "50", "Black").Now about the second point, I've added a Button1 which should take the Textbox1/2.Text and the Combobox1 selected item and replace the values(aka separator(1)) in the text file. The problem is I don't have any idea at the moment how to do it. What method should I use?
I have a button (btnAdd) that adds the content of a textbox (txtName) to a textblock (lblName). I want to add a date to the textblock when btnAdd is pressed but I want it to be a different font size and colour. So far my code looks like
lblName.Text = txtName.Text " " + DateTime.Now
I only want DateTime.Now to be a different size and colour. Is this possible? Instead of a label I need to display it in a listBox. My new code:
listBox1.Items.Add(txtName.Text " " + DateTime.Now)
Is there a way of putting a block of text (ie a paragraph) without using the label tool?
