I am trying to auto tab to the next text box after my limit of characters has been reached in a text box. Visual Basic 2010 Can this be set in the properties? I have 7 boxes, each allowed to hold only one character.
View 5 RepliesI'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

Okay, I've got a datagridview in my WinForms app that auto-builds the column list from a datatable schema. It's working fine, except that it allows the user to enter values too long for the database field. For example, I have a "name" field that is defined in the Sql-Server database as a varchar(50). Is there any way to limit that cell (column?) so that it only accepts 50 characters? Right now it lets them enter anything and throws an exception later.

View 4 RepliesI'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...
When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?
I'm just now starting to work on something that works 'like' an ide, where it will auto space my text as I type. I really JUST started and I'm not sure if I'm even doing it remotely like I should. anyways, what I'm doing is on TextChanged (eventually I'll just do it on newline but that can wait) it gets the contents of the text box, puts each line into a string array, trims the excess whitespace, see's if it has a keyword in it, and then adds some whitespace to it if it does.I know I'm doing something wrong with either my declarations or my error handling. Mostly because i'm not sure how to work with string arrays, can you help me with my syntax?[code]

I am in a need of a Regular Expression to restrict input to only certain characters in a text box. The text box can only allow 0 or 1 "+" sign at the beginning and at no other position. The text box can only allow 0 or 1 ":" sign not before the "+" sign. The text box can allow any number of 0-9 digits.

I'm trying to create my own custom "inputbox" (can't think of VB.Net term for the VB6 input box).
Anyways, I'd like to have a label & a textbox on my form along with 2 buttons. I want to let the label to grow based on the text that is in it. I know it has an autosize feature to it, and guess I can use that, how do I limit the width so that once it hits that limit it goes to a new line so that if I have a message or a question to pose to the user, it doesn't get too wide. Kind of like MessageBox.Show.
It'll be Label at the top, textbox under that, and the two buttons under that. I'd like the textbox to move up/down based on the size of the label, and the buttons to do the same along with the window not becoming too wide.

I have a big issue which I have been struggling with for days now. I have a richtextbox where users Can input text and print it.
My problem is that i don't want to allow more than one page to be printed so i need to prevent the users in inputting more text than what fits to one page.
I have word wrap set to True which means that i really can't count the lines since they are determined by number of return/enter hits. I can't set the character to a max because blank Lines and spaces Can cause this to differ very much.
What i really need i a way to prevent the users in inserting more text than would fit inside the richtextbox frame and the frame may not be resizeble.

i tried this
TextBox3.Text.Remove(3)
I'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

The text will not have any special characters or numbers, just alphabet letters.

View 4 RepliesI need to limit the 1 line text entered in a XtraGrid repository editor to its column fixed width. I cannot use a monospaced font and MaxLenght because this field will be shown in a report.In KeyPress event handler I tried to create a Label, put the string on it and compare its PreferedSize. Width to the column's Width. It almost worked well but is not easy to control Paste operations if I have to remove the exceeding chars (f.ex.: if I change the text value, the cursor jumps to 0).I also tried using ActiveEditor. CreateGraphics. Measure String but cannot get it to draw(measure) the text the same way DevExpress does.If I could catch a Before_WordWrap event it would be a solution.
View 1 RepliesI want to limit the Textbox to a range of characters in VB. For example, I want the user to enter strings from 5-7 characters. I know how to limit the Textbox to a certain number of characters by MaxLength but that will give him the option of writing just 3 or 4 characters which I don't want to allow that from happening.
View 4 RepliesI have 200 dynamic textboxes.
I am trying to limit the user input to exactly 5 characters ( not more, not less ), and numeric only.
I have been trying this :
Private Function txtValid()
Dim str As String
For Each txt As TextBox In Panel1.Controls
[Code]....
But it always shows the last messagebox. Not all 200 textboxes will be filled in, so I suspect that it may have something to do with that, but I just need to stop the user from entering alphabetical characters, and the entered field must have a length of 5
what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.
Is there a limit of characters for DocumentText of the WebBrowser control? When I try to copy it to the clipboard, it is always truncated.
View 14 RepliesBasically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work
