I have several text boxes (1-4) that I need to limit to ONLY numbers.
I need a minimum value of 1 and a maximum value of 99999.
I just don't want letters or special characters ($,#,%,@) to be allowed. Numbers only.
I wanted to set a maximum limit of characters of textbox in the properties but i can't find where it is located unlike in vb 6.0 you can set the characters in maxlength...

View 5 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
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 RepliesDo multiline textboxes have a character limit?Someone who was using my program said that he has some textfiles that are about 50 KB and when he goes to copy/paste that data into a multiline textbox, he only gets about 31.9KB of the data.My MaxLength property says 32767, which basically matches the 31.9 KB, however, most of what I read on the internet says Multiline Textboxes can hold unlimited characters and that MaxLength is actually ignored when a textbox is in multiline mode.

First method check only numbers with decimal point. second method check only A to Z or a to z with some specify charecters. In java it is very easy by the parse INt methods or use class.

View 3 RepliesI figured there would be some simple way to set up some textboxes to allow ONLY numbers or ONLY characters, however I haven't found an easy way yet.

View 1 RepliesEssentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

View 3 RepliesI need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If
Next
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?

Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.
I'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 ?

I know that the topic is kind of weird, but I will explain that here. I am reading text from a text box and inserting that into a listbox. I am wanting to read what the user inputs into the text box and add a character between each character they type. Here is what im wanting to do written out[code]...

I have a Form with 4 Textboxes. The Textboxes are multiline. To write the contents of the 4 textboxes, I did the following.

How do I read to or populate the Textboxes using StreamReader or StringReader or other means?
So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?
