Sql - Escaping Special Characters Combinedly At VB Code And Oracle?
Apr 6, 2012
In SQL I had to alias my column header with some text containing special character, So to mask these characters {}, I had to keep them in double qoutes.
eg: select column1 as "{Ctrix}" from table; When ran in sql the result is
{Ctrix}
-------

The problem that I got was while passing the same above query in the code that I had written in VB.strSQL="select column1 as "{Ctrix}" from table;" The query is getting truncated and giving error. Please help me, how to handle this properly at sql/vb... which satisfies both.

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 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

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.

I have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.
What I have so far:
If Val(txtEntered.Text) < 0 Or
(IsNumeric(txtEntered.Text) = False) Then
MsgBox("Sorry, but letters are not allowed!")

To automate mailmerge function in word, i need to join different elements to complete the mailmergedatasource. In one of these file are words with special characters like ©, §,¨, .... When openng these files for reading, streamreader transfoms the characters to unreadable signs. When i give a type to use to open like ASCII, Unicode,it works for one or tho characters but not for all. I have the same problem when the character is read correctly, with streamwriter output to a textfile. Word cannot read the textfile and ask to define which type of coding should be used. In most of the cases not all the characters can be converted to readable characters.
