How to update the text from the TextBox control? Consider a TextBox that already contains the string "Wel"
To insert text in the TextBox, I use: TextBox1.Text = TextBox1.Text.Insert(3, "come")
And to remove characters from the TextBox: TextBox1.Text = TextBox1.Text.Remove(3, 4)

I have a couple of dropdown lists like this
<asp:DropDownList runat="server" OnSelectedIndexChanged="Update_ddls" AutoPostBack="true" ID="ddl1" />
<asp:DropDownList runat="server" ID="ddl2" />
[Code]...
I also have a function called Update_ddls which runs OnSelectedIndexChanged that looks like this
ddl2.Items.Remove(ddl2.Items.FindByValue(ddl1.SelectedValue.ToString()))
Which removes the selected item in ddl1 from the second dropdown but if I keep changing the ddl1 item then ddl2 won't have any items left in it.
Is there a way to re-add the previously deleted items in the Update_dlls function without re-databinding because if I re-databind I lose the selected item in the ddl?
Here is my code to insert h2 tags and remove them around selected text:-

I have a form with four checkboxs and a textbox for an id number.I also have two tables in a database. The first has a column for the users Id, Name, and a column called Points.The second has a column for Id and one called Letters.What i want to do is, after the user enters the id number, and the user clicks checkboxA it should add a certain number, lets say 5, to the "points" cell for that id#(in the first database), and it should put the letter "a" in the "letters" column (of the second database) for that id number. Also, if a user deselects a checkbox it should remove the "a" from letters and subtract 5 from points.Also there will be different letters in the "letters" cell, so i cant just clear it, but i have to remove the specific letter.

I need to remove a letter from the string each time it loops through the string until there is only 1 letter left in the string.
I got that little function(I changed the name of variables)
Private Function everythingLinked(ByRef myClass As cls, ByVal found As Boolean) As Boolean
If Not found AndAlso myClass.checked = False Then
myClass.checked = True
[code]....
I want to rewrite it so it would only be loop and no recursion and I'm currently lost?I'm passing a class to this function(with a starting value for found as false) to know if it is linked to the middle of the tree. The class got an array with a maximum of 4 link to other class and it can be circular(this is why I have a checked_link boolean).It does the recursion until there is no more link(return false) to check or until it find the middle link(return true).
edit?for an example, this
in pos 0 got link with 1
in pos 0 got link with 6
in pos 1 got link with 0
[code]....
middlepoint would be pos 15 the code above can prove that every position can be linked with the middlepoint so initial arg would be
everythingLinked(random pos, false)
and in this case it would be always true
I use the removeRange function to remove a couple elements from a list, but the Count of the list seems to be intact, so I assume it didn't work the way I expected it too.... so, how do you remove elements? I mean, reduce the list's Count value ultimately.
View 3 RepliesI have a website where people send each other messages Recently I noticed that sometimes the same message is sent more than once
For example, a message is sent four times within three seconds or twice within a second.I do not understand how this could happen, once the user clicks on the button that sends the message .So all the window switches and a message showup saying "the mail is sent successfully." I checked that if the user refreshes the page after it sends a message, then really the message is sent again.But I do not think that's the case, becouse the message is sent twice within one second.I am writing in vb.net and using mysql data base.Maybe it's related to the queue for the db, i do not know.Here's the code:
Function calls:
Call GlobalFunction.update_mailbox_table(user_id, receiverId, txtMessage.Text, private_picture)

I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:

secondFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "2.txt").Split(vbNewLine)

This is related to "Next form won't display" topic.

This may sound a daft question but how can you remove the caret from a textbox after the text has been entered without having to use the mouse to click outside the box.The reason for this is I have a textbox which when the user clicks the mouse on it a virtual keyboard allows them to enter text which is then displayed in the textbox. If the user got it wrong and wanted to reload the virtual keyboard they have to move the mouse outside the box, click and then re-enter again.
