Here there are 2 wild characters (') in the text. When i try to insert this text in database, the problem is comming. The whole string should be inserted as it is, as well as to be retrieved as it is.

Recently I have started my computing course at college. I had little programming knowledge (as I'm more of a 'web developer') and it has come to the point of us learning some of the basics.I downloaded VB at home, and have been learning by myself when I have the chance... but I've hit a wall Basically, I have to create a program that searches for a character within a string.I managed to do this at college, but it has slipped my mind... So I could use some help The specification we have to meet is:An event (such as a button being clicked) must use a function to return something.The function must use the mid() function
From this, I've come up with:
Public Class Form1
Dim string1, searchterm As String
[code].....
The layout of my program is effectively 2 text boxes (named input1 & searchterm), a Label (named Output1) and a button (named search).ow, My problem (I think) is due to the mid().I'm not entirely sure I've used it correctly.

I know this has been answered before but I am having trouble with it still. I am trying to find if a textbox has an "x" as the first character. I am trying to use the left(string, 1) command as described in a couple other threads to just test the first character on the left but the only left function I can find relates to the left coordinates of the textbox.

Basically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted.
My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was.

I am Looking for a combobox that does a full search and O mean by that the following :
It starts searching data upon inserting or adding new character to the textbox of the combobox and vice-versa, which means that if I moved back by deleting a character then it starts searching again selecting the first data resembles the textbox. In another way I want a combobox class does exactly the same as combobox in Encylopedia.

I am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.
using the
WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'
produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.

I've done this, the way i've always done it .. 100's of times before.. and now on this one form... bombs out... and will not linkup ...I have a DGV with 101 columns, and on this form only one of the coulmns requires a ComboBox (Drop Down List). It's the run's Status, and is one of three values..Pending, Running, Complete... so i'm loading the Combobox Datasource with a List (Of {Object}), like i do on several other DGVCombo Boxes within the same project.. (other forms)

I am trying to read the file contents using
System.IO.File.ReadAllText
After reading the file contents the special charaters gets replaced with some garbage characters like "?".
To eliminate this I have used encoding along with above method
System.IO.File.ReadAllText(strFile, System.Text.Encoding.ASCII)
But still it is not working.

I 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.

In 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.
