I have a datagrid control with a list of names that it retrieves from a MySql database. I can search through them until i have one result. I want to be able to Display a groupbox control when the number of results is equal to 1. Also, in the groupbox i have a button that when clicked will delete this user from the server and their information from the mysql table called "employee". when the user is deleted i'll display a confirmation message in a messagebox, and reload the table with the updated list. so far the only two problems i have are showing the groupbox when the results are equal to 1 and deleting the user from the sql server based on the name of the search result

In mysql this character 💀 cause error Incorrect string value: 'xF0x9Fx92x80'
Samples of these characters are from [URL]
Say I want to analyze data from the web and found some strange character
how to remove this character 💀 ??
The occurance is rare.
In fact, how to know all characters that may be problematic for mysql and remove that? I am not saying escapeable characers. I am saying characters that are neither numeric, alphabeth, or chinese scripts, or punctuation. Characters that's totally bizarre.

Basically I'm using the following code to access a php file I created that creates an XML formatted page.
xmlFile = XmlReader.Create("http://www.serysoft.com/webservice.php", New XmlReaderSettings())
The purpose of webservice.php is simply to access my MySQL DB and put the relevant data in tags. Then I use:
Dim ds As New DataSet ds.ReadXml(xmlFile) vi.user_version = currentVersion
[Code]....
To stick the information in a dataset then read that information into a Public Structure I have created. This is all contained inside a DLL which is being referenced by my main program.
The issue I'm having is that in the SQL DB, the "notes" field is a BLOB. I have information that needs to retain line feeds. However, when put into the XML format, it loses the line feeds and becomes one line.
Do I need to talk to someone about PHP to get this done? Or is there some known way to handle such a thing as far as XML goes?
