I have a string which at some point contains the set of characters in the following format [123]. What I would like to do is get the characters between [] but the characters in between are never the same length.
View 4 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.

i have been trying to remove special characters. i am not able to remove many crlf in middile of the string.
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.
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 ?
View 4 RepliesI 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]...
View 4 Repliesexample. i have 2 textboxes and if there empty it says "Incorrect Information", but how do i make it that like when a person enters something into the textbox1 it can be 3 values minimum.. like it could be eather 2 letters 1 number or what ever just more than 3 values (no special characters), and on the password.. 6 values minimum (no special characters).

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?

View 3 RepliesThis is my first post at the forums, if I did something wrong making this topic Okey so here is the deal. The program task is to take 50 codes including letters and numbers. Take them and insert them into a webpage(webbrowser1) witch is designed to deal with these codes(3 fields). To check if the codes is valid etc.
Here is what I got :
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox1.Text)
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox2.Text) '
WebBrowser1.document.GetElementById("Website textbox ID here").SetAttribute("value", TextBox3.Text) '
What this does it takes textbox1.text input(first part of code) and inserts in the first field at the website.The to others to exactly the same.But instead of having 3 diffrent texboxes I want it like in this pic.
I have been asked to read text out of a Word document, convert to UTF-8, then write them to an xml file with their character codes. On a scale from 1 to 10, I have about .0001 experience with encoding, so I will try to explain and answer questions to the best of my knowledge.

The string displays correctly between the characters, however I do not wish to see these characters. Here is my code that I used from a serial comm chat. P.S. this displays on two lines, the characters that I'm asking about are on the second line.

While my user is typing text into a textbox i want the characters " to be replaced with ' '. The thing is, when i put ' ' in the replace code, it thinks it is a comment so i cannot run the code without producing an error.Also in my multitext box, everytime i write text and hit ENTER, save and then load it back again, the last line ends with a comma, so:
Line 1
Line 2,
When the text is written to the file i read from, it will show like this:
"Line 1Line 2",
So i need a way of trimming ", when the apostrophe " and the comma , are together. My code already trims "".
