Web Forms :: DropDownList FindByText With Special Characters?

Aug 24, 2010

I have a dropdownlist which I dynamically select a list item using findbytext as long as there are no special characters. One entry in the list starts with a percent symbol which I have been unable to dyncamically select. I have confirmed that there are no spaces in the list item and have hard coded the query with the string to try to find the problem. FindByText("% Increase") I believe it has something to do with the special character but have been unable to identify a method to work around this.

VB
If
Not ddlColumns1.Items.FindByText(strDefault)
Is
Nothing
Then
ddlColumns1.Items.FindByText(strDefault).Selected = True

How To Fix Special Characters In String

Aug 3, 2010

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()

Special Characters In SQL-Query

Jul 21, 2010

I'm fairly new to ASP.NET and have the following problem:

I add data to an Access database through a form on a aspx.-page. Now my problem is, if the user enters characters like " or & the syntax of the SQL command i send to access changes and the whole thing crashes. :-(

It should nevertheless be possible to write special characters in the Access database. How can I do that??

Seconde question:

I put a GridView under my form to display the data entries from the access database to the user. This GridView has 3 Options in every Line at the beginning (Edit, Delete and Select) by default. OK, when i klick on Delete it comes the following error message (hand-translated from german into english ;-] )

"Deleting is not suppoorted from the datasource "AccessDataSource" unless the DeleteCommand is not specified.

[NotSupportedException: Das Löschen wird von der Datenquelle "AccessDataSource2" nicht unterstützt, sofern nicht DeleteCommand angegeben wurde.]

The equvivalent error message appears when I klick on the "Edit"-Button...
How do I have to specified the Delete and EditCommand?

.net - Put Escape Character Before Special Characters Using C#?

Aug 15, 2010

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
