[2005] Setting ForColor On Text From A Disabled Textbox + Removing The Right Bar
Jan 7, 2009
As some of you are aware of, I am fairly new to VB.NET. I am trying to learn as much as I can. I have a textbox which is set to multiline. It's setup to accept a maximum of 500 characters (10 lines of 50). First of all, since it's size is fixed, how can I remove the right bar on the left as im not using it (the scrolling bar).
#2, once a user click on a button, I disable the textbox and display the text. I can set the background color, however it looks like when the textbox is disabled, text is gray and can't be changed. A fix I found is to use a label and hide the textbox, but are there any easier way ?

Private Sub CopySelectedNodes(ByVal nodes As TreeNodeCollection)
For Each node As TreeNode In nodes
If node.Checked Then
'MessageBox.Show(node.FullPath)
Me.CopySelectedNodes(node.Nodes)
[Code] .....
This does not work, I want to loop through results so the textbox1 will be like 151,154,3,151, and I want to remove the last.

I am writing an app that writes notes, inserted by the user, to a txt file. The app saves that notes to a txt file, and when opening it reads the file and shows the already inserted notes. However, I want the user to be able to delete some of those notes...but I can't seem to do it...this is what I have:
VB
Dim file As New FileStream(data_path & "notes.txt", FileMode.Open)
Dim text As String = Nothing
Dim reader As New StreamReader(file)
[Code]....
It goes fine, but the text.Replace(value, "") line doesn't seem to work. I've also tried text.Remove(0) but it doesn't removes the line...it looks like it has no effect.

I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?

I have a small requirement and that is as follows:
I am populating a ListBox using stored procedures and the ListBox is populated as follows:
lstItems.DisplayMember = "emp_name"
lstItems.ValueMember = "login_id"
lstItems.DataSource = accessFunction.getEmployees
The ListBox gets populated correctly. After it is populated, i have a CommandButton and on the click event of the button, i want to remove selected items from the ListBox. So in the click event of the CommandButton, i have written the following code:
lstItems.Items.Remove(lstItems.SelectedItem)
After selecting an item from the ListBox and when i click the CommandButton, i get an error as "Items collection cannot be modified when the DataSource property is set".
how i can delete items from the ListBox.

I have a multi-line textBox disabled through vb.net :
myTxtA.enabled= false
The html it outputs :
<textarea name="myTxtA" rows="10" id="myTxtA" disabled="disabled" style="width:99%;">
...
</textarea>
That's the source code I get through the browser but the textArea is still editable in the browser. There is no javascript modifying myTxtA, and the only other reference to myTxtA in my codeFile is the following :
If somethingNotHappeningHere Then
myTxtA.ReadOnly = True
End If
I can't see why my textarea is still editable. Can the class of the div containing the textArea modify its behaviour ?
PS: I am not concerned about if the data is sent or not. I'm just looking for the textArea to be uneditable.
Edit: Same problem on IE7 and Firefox 3.5
Edit 2: When I copy all the html source from my browser into a new html file the textarea is properly disabled...

I'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True
textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
UPDATE:I tried to use WIN32 API but it didn't work as expected:
Imports System.Windows.Forms
Imports System.Runtime.InteropServices
Public Class TestTextBox

I guess in simpler terms what I am trying to do is get the post value of a disabled textbox to use in a SQL insert statement when the form is posted. I need to get the value of a text box that is disabled with javascript. Ultimately I will use the value as a parameter of a SQL insert statement. I have read that I need to get the value by doing something like this:

I've been searching all over the interwebs this afternoon trying to find a way to change the color of a disabled text box. As it stands, I'm still working on my first program (A very simple, select a shape from a combo box and input values and the program gives you the area) and I have it working well enough, I'm just working on cleaning up my code and changing that disabled text box color. As it stands, the default disabled color is very similar to the enabled color, and I don't want to just change the enabled color. I'd rather change the disabled to work with the scheme a little better.

im using iTextSharp to read a PDF (both password protected and not), i was able to get most of what i need but ran into a problem when the document that im trying to read has some disabled text select (this is the feature where you cant copy-paste the content of a PDF file)what im working on is to render the content of the PDF in HTML form so that i can highlight whichever is needed and group the selected text to whichever category it fits (like tagging a word or a sentence)i checked every byte which was extracted from the PDF but it doesnt contain any of the unselectable text?
Code:
Imports iTextSharp.text.pdf

ok so I am already able to send certain text to the webbrowsers textbox on pageload. NOW I want to add text to it if I push button2. basically I want my program to add more text to the webbrowsers textbox only in certain cases.
here is the code I have to add to the textbox in the webbrowser (it doesnt have a "name" so I have to do it like this):
vbcode
Dim HTML4 As HtmlDocument
Dim HTMLI4 As HtmlElement
HTML4 = WebBrowser1.Document
[Code].....
for my testing I am doing the above on a button1.click. So HOW could I successfully add text to that textbox in the webbrowser if I did a button2.click? For example, if I wanted to add the text: "Billy loves to play baseball". does that make sense?? I tried putting the same code in a button2.click command and all it does is erases and replaces the text into the textbox. I want to add it to the text that is already there.
