What do I use to find the position of a certain character in a string? Lets say I had a number 12345.6789 I want to know how far the decimal point is from the left? Of course the position of the decimal will change as the number will change.

I want to get every character one by one and put it in array.I tried to use Split function but I think there is no delimiter for such kind.
My problem seems simple but I can't find an answer for it.I need to be able to pull a phone number (string) from an entire string. example: "My phone number is (xxx) xxx-xxxx, call me as soon as possible."
Its obvious to me that the phone number should be able to change depending on who you are talking too. So the question becomes, how do i search for the phone number's format within the above string?

I have tried a Replace(text, Chr(196), Chr(45)) but it isn't working so it can't be 196. Is there a tool or something where I can copy this character and paste it into the tool and it will tell me what char code it is?

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
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 somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.

I have an existing invoice module that displays its items in datagridview. The datagridview also contains DataGridViewComboBoxColumn. The problem with the datagridviewcomboboxcolumn is that it has too many records which results to performance problems. And the datagridview itself poses some performance problems dealing with the data.
An idea is playing in my mind to redesign the module, and i want to ask some of your suggestions on other alternatives for datagridview that can display and handle many records at the same time and can handle each row that has datagridviewcomboboxcolumn with also many records.To illustrate concretely, the datagridviewcomboboxcolumn contains the Product Items and the datagridview itself contains records and details such as quantity, rate, total amount of the product item selected.
Does VB have an equivalent to the @ symbol in C# to quickly and efficiently escape a SQL command line string?

I think VB has a way of doing this, but for the life of me I can't find it. I want to search through a string for anything contained between two certain characters, e.g between 2 | characters. I'm not sure if I want to split the string at this point, but I only want anything contained between the two | markers. So for example if the string reads |ABC|DEF I only want to retrieve the ABC, but not the DEF as it's not completed yet.
View 3 RepliesI want to be able to find both spaces using the indexof method. Here's my code so far. Basically the program will turn the string "Will Smith" to "Smith, Will" But I noticed when I type in a name with a middle initial or middle name "Will J Smith" I would get "J Smith, Will" And I want to be able to find that second space when its there and apply a code that would produce "Smith, Will J" When there is a second space. How would I go about doing so?

Basically what I'm trying to achieve is to extract all the words within a piece of string and transfer that from one text box to another text box.
An example piece of the string would be
<laugh:894u8438:4434:words>
However the words within the string will never remain constant and the characters before and after will change. Is there anything that will read the string and take a word from the string without it being pre-programmed. The string it is reading from is uploaded from a text file.
