Limit The User Input To Exactly 5 Characters?

Mar 11, 2011

I 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

VS 2010 : How To Limit Maskedtextbox Input

Feb 25, 2011

I have a maskedtextbox that i want to limit character input in it but i can't manage to figure it out.The date type is "yyyy-mm-dd" and the mask is "1300/00/00" (it is not gregorian calender, it is persian )In the TextChanged event i am changing the bindingsource filter.Because of this i don't want the user enters invalid date. For example the user enters 9 in here : "1300/90/00" i want to prevent this from happening before TextChanged event occur. (the place isn't important i just want to stop user from entering an invalid month or day)I have tried the KeyPress event but i don't know how to detect where in the textbox user is entering a character.

Note that i know already how to validate and i have a code for that but the TypeValidationCompleted event occur when user does all changes and leave the textbox.

Prevent A Textbox From Receiving User Input?

May 5, 2010

Preferably without turning the "Enabled" property to false, because I still need to output text from it.

I made a custom control in which there is a textbox but I want it used only as an output control, for showing text and stuff. Problem is that as soon as my form opens up the focus is turned to the textbox and I cannot catch my keyboard events on the form anymore(since the other controls are pictureboxes). I need a way to make this box "unclickable" or any way in which it is impossible to attribute the focus.[url]...

Runtime Added Textbox Not Accepting User Input

Dec 23, 2009

I have a form, with lables and textboxes added at runtime. The labels and textboxes are added properly on form load and display as expected. The form allows tabing into each of the textboxes, but the textbox does not allow user input.

Is this a problem with the way I show the form to the user? >> this particular form is called (frmname.show) from a different form -- If I test this form directly, without being called from a different form, it allows user input in the textboxes. Is it because of the properties I used to create the textbox? >> properties used were - .name, .size, .location, .tag

Richtextbox-how To Limit Input Of Text

Mar 11, 2010

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.
