I have a streamreader that is reading a file that has the possibility of having the contained information being separated by either a space, a semicolon or a comma, or even a page break.How can I check for all those things and then place them in a array?'I know this is the way to check for one character, how do I add on to this?
arrDataHolder = txtDocument.Split(CChar(","))
My form has a texbox where user enters an ID. IDmust be4 chracters in length andof the form: begins with either "E" or "e" and the next 3 chracters cannot be "all characters".
Example:
E102 - corect
e3ff - correct
[code].....
I need to check if a character is a valid Key (type) in VB.NET (I need to turn "K" into Keys.K, for example). I am currently doing this to convert it:
Keys.Parse(GetType(Keys), key, False)
How can I check if a StringBuilder contains a certain character or string? There is no Contains method like the string class has.
View 8 RepliesSometimes when backing up an sql file using phpmyadmin (database stuff), for some reason it forgets to double up a single quote, resulting in an error when loading the sql file back into the database when required. A line in such an sql file looks like this;[code]As shown in the example, phpmyadmin did double up the quote in "you're" as it should, but it forgot to double up the one after "27", resulting in an error.As you can see it's like this (*value*, *'value'*, (and so on) but beforehand I can;
A) Never know how many values are in such a string
B) Can't simply split the values by "," because the value itself can hold a comma aswel.
It would be easy if every value was like this; *'value'* because then I could split by " ', ' " but that's not the case, and I also never know what location the values not enclosed in single quotes are. I also can't simply double up all single quotes in the entire string because then it will also double up the ones that are enclosing the values, resulting in an error during upload again.So yeah, what I need to get done is single out all the values with regex ($1, $2 etc.) and then string.replace single quotes in those values but *only* if said single quote is not preceeded or followed by another single quote, else it would become a tripple quote resulting in an error again.
I am trying to check if a users input contains any special characters from a list, does anyone know who I would go about doing this?
I've tried the LIKE operator:
Dim sMatch As Boolean = tTitle.Text Like "[-/,.:;*?""""<>|&'[]^%£$()_+=!#]"
but doesn't seem to work, i think special characters are used for settings.
Is there a RegEx i could use for this??
How would I check a given string for the presence of any match with a character listed in another string. I'm just looking for a binary result.
In other words, how would I write the VB.NET function called IsPresent in the following code snippet?
Result = IsPresent(AnyString, MyTestString)
For example, if MyTestString = "XYZ" then I want the following results for the given AnyString values:
MUTTON, Result = No
BUZZ, Result = Yes
HAPPY, Result = Yes
FISH, Result = No
How to check the Single byte character (e.g. English) and Double bytes character(e.g. Chinese) ?
Since I want to printing out their code which are representing in Hex.
However, Single byte character is using 2 digits of Hex. And Double bytes character is using 4 digits of Hex.
So, how can I check them and output with more readable pattern ?
input likes: 微軟 Microsoft output likes: B74C B36E 4D 69 63 72 6F 73 6F 66 74
Is there a way I can check the place of the character in a line or string? For example: I want them to guess 1214 So how would I make sure each character is in the right place?

View 3 RepliesI am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

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.

View 7 RepliesIn my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.

i use this code to split a words:
Dim sWord As String = "Word1~Word2~Word3~Word4"
Dim sResult As String() = sWord.Split(New Char() {"~"c}, StringSplitOptions.RemoveEmptyEntries)
so that a messagebox can show
Word1
Word2
Word3

but how about if the character to split are 2 or more character instead of "~"? because sometimes "~" is used in some documentation.. i prefer to user "!~!" or "D-:" in splitting words..
