Store Special Characters From User Input To Sql DB?
Jun 24, 2010
I have a field that the gets a case title. Requirments are to be able to use any of these special characters in any order in the title.
,,.,:,;,",(,),'
i.e. (test, case.) "title" with; 'special: chars'
I can't just take that string from the test box and put it into the sql statement. It will error.
I need to be able to 'escape' the special characters to play nice with sql server 2005
Public Shared Function Format(ByVal str As String) As String
'Format = Regex.Replace(str, """", """""")
'Format = Regex.Replace(str, "'", """'")

Essentially 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 am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

Someone gave me a link to a Multi-User TCP Chat application once, but, there is a flaw in it, where it wont do special characters, such as Alt+1 will become a different character to the server than the one that was sent. Even I tried to see if the output was usable but it sees it as multiple chars, when it is only 1, and I can't find a link between what it sends and what the character is, so I can't just tell it based on whats sent what the char is, because I see no relation, I would have to type it out for each and every special character.

I 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

how to pass user entered data (from a textbox) to an array? All the examples I have found show how to populate an array with predefined values. Heres what I've got, its messing and not close to what I want.
Private Sub AddButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddButton.Click
Dim AddNumInteger As Integer
[Code].....
When the users clicks the add button the value they entered in the NumAdd textbox is sent to an element?

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

for example if a person types in multiple characters that represent a certain image in the input box for example if i type "tom" in the input box each letter represents a different image. Can i display those 3 images on the form somewhere? this is what i have so far...
Dim character As String = InputBox("Please enter a word")
I know that much but im not sure how i can connect the letter with a image for example
PictureBox1.Image = My.Resources.pic02

I've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„¢ or â€" etc"
When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.Here's how I build the text file (where feedStr is a StringBuilder)
objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()

buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case I want it to be written in c# or VB.NET

I have a text file, the file is sent to me, but this file has a particularity, because between characters get special characters, as if the file was a binary file.I put a screenshot. I need to pick up and replace these characters by the character "-", those chracters are at position 13 to 18 on all lines. And sometimes there is a "\n" character that makes it split the line, and this should not happen.

In C# you can use to ignore the special characters:
string myString = "this is a " string";
that would work as one complete string... in VB, doing that does not work...Anyone know the equivalent of to ignore special characters for VB

I've received a text file in which the text is like this, ãYAHOO.COM. When I'm debugging in Visual Studio, the value I see for the character is "�"c. Firstly can anyone tell what is the character before yahoo. Is it a special character or some html character, and what is the character that I'm seeing in VS while debugging.So it goes like this, the ascii value of the character turns out to be 63.But when I write the value to a file it generates 3 characters whose ascii values are above 127.
