Detect If A Character Is Inputed In Wrong Place By User?
Jan 19, 2009
Below is the code i am using for user input which works fine apart from one thing that i can not work out how to do.I want to detect if a user had inputed a character in the wrong place. The correct input is:
D:Folder name
The incorrect input is:
D:Folder name
How would i detect the extra '' at the end?
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
Select Case Doc.Text
Case ""
MsgBox("Invalid Path")

I'm trying to include a user control in an aspx page, it works fine, but my control does position itself where I want it and always appears at the very top of the page. Could it have something to do with the masterpage? I've tried registering the user control in the master page, but I don't know how to reference it in the content page.[code]

I have a byte array that I'm encoding to a string:[code]Then I write that to a file via IO.File.AppendAllText.If I open that file in 010 Editor (to view the binary data) it displays as this:47 43 44 53 79 73 74 65 6D 73 3F 0A 01 32 31 36..The original byte array contained 89 at position 11, and the encoded string contains 3F.If I change my encoding to Encoding.Default.GetString, it gives me:47 43 44 53 79 73 74 65 6D 73 E2 80 B0 0A 01 32 31 36.

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

I have a String with 15 places that I would like to split into 3 pieces: (First 3 digits), (next 3 digits), (remaining 9 digits).
How in VB2008 can I do that? Everything I have read so far indicates seperating by a certain character (ie: "," or " ") but no mention of character place. Seems like a simple thing, but after 2 hours of searching I'm still coming up empty

I am using this line of code to place a special character in a textbox at the cursor location:
Me.RichTextBoxPrintCtrl0.Text = Me.RichTextBox.Text.Insert(cursorloc, "ῳ")
It works good, but after it has been done, if you try to undo the action by pressing control Z, for example, it is not undoable. Is there a way to make the action undoable?

so in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.
For example, I'd take in a line of the series of lines: hello:world@yay
I'd want to break it into three separate strings of "hello", "world", and "yay".
How would I do such a thing in VB.NET?

I'm writing a program and it's got a textbox for the user to enter values. Since the textbox text property should only be a "number", my program need to detect invalid charaters like "*/&()$" and tell the user to only enter a number. Does anyone have an idea how to do that?

Is there a way to detect a Chinese character in a string which is build like this:
dim test as string = "letters 中國的"
Now I want to substring only the Chinese characters. But my code is database driven, so I can't substring it, because the length is always different. So is there a way I can split the string, from the moment I detect a Chinese character?

How do I make a regex that can detect a certain character string that is either all by its self in a line, or separated by white space.
If I have the line:
"ot"
Or the line
"sdf gdfg dv ewrsef fvdf ot sdfsd sdot"
I want to be able to detect the 'ot', except for the one that is 'sdot'

I am currently making a boggle game, I have done finished every aspect of it expect the spell check bit. I have been searching the internet fruitlessly, and have only found spellcheckers but none of the results allow the program to know the word is wrong. So what I want my program to do is after the user has pressed done or the timer runs out, it checks the items in listbox1 and if it is wrong then puts the item in listbox2.

I don't like validating through the TextChanged event either as I believe that to be the cause of some issues. Doesn't the Textchanged event validate on each time a letter is typed?

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

We are using sAMAccountName for User Id in active directory ,but the sAMAccountName active directory attribute is taking only 20 characters.So now I am trying to use "user principal name" (UPN) as a User Id in my application .what are the merit's and demerit's of using UPN in place of sAMAccountName for user Id.Also I have seen when I create the Email Id as a User ID then all the right characters along with "@" sign are saved in the domain name dropdown list. Can I use the "user principal name" (UPN) to save user ID in my application with email Id type names with this active directory functionality.

I have a user control which is essentially a main menu I can place it into my MasterPage hard-coded, but I don't want that, I want to be able to dynamically place it with the code behind of the MasterPage.
<controls:mainMenu ID='MainMenu1' runat='server' />
So what I am looking to do is something like
if **condition is true ** _ response.write('<controls:mainMenu ID='MainMenu1' runat='server' />')
Of course, I know that won't work, but how would I place the control based on a condition in code behind on the master page?
