VbCrLf Keeps Replacing Text In A Text Box When It's Meant To Be Displaying The Next Block Of Text Below It?

Mar 14, 2011

I'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?

Editing Text In A DataGridViewComboBoxColumn?

Jul 31, 2008

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.

Mar 22, 2010

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?

Treeview - Add New Node And Select Text For Editing

Jun 27, 2009

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")

VS 2008 Reading And Editing Text File?

Jul 23, 2010

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.

Block All Special Characters Entered In A Text Box?

Sep 26, 2011

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!")

VS 2010 Editing Text File Specific Lines?

Feb 13, 2012

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:


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?

Combobox Bug - Text Typed In Combobox Appears In Another Control (textbox) On The Form?

Feb 20, 2012

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls.  For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button.  I have no issues reusing the shared user controls, in this case.  My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.

Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists. 

The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource.  Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality.  Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today.  I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly).  Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening.  At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

JQuery - Retrieving Info From HTML Input Text Block

Now I need to retrieve that info with VB.Net and ASP.Net. I just changed the HTML input box to Textbox. Then added the OnTextChanged function call when the text is changed, and called a function that stores that date into my class.

As such:
Start date:
<asp:TextBox name="startDate" ID="startDate" OnTextChanged="startDate_TextChanged" runat="server" AutoPostBack="True"></asp:TextBox>
I tried to go with asp:TextBox before, but for some reason JQuery didn't work on it.
