OK, Marvin, try this: string temp = textBox1.Text.Replace("'", "''"); string sqll = ("select uic,namehu,phyaddress,contactinfor,emaila,joinedon,expireson from clientinfor where namehu LIKE '%" + temp + "%' or phyaddress LIKE '%" + temp + "%' or uic LIKE '%" + temp + "%'");

Incidentally, you can always use the same code whether the string in the textbox contains apostrophes or not. If it doesn't, then Replace will have no effect.

right

Vulpes · Answer

I take it you mean apostrophe rather than hyphen. When you search for a string s, say, try searching instead for: s.Replace("'", "''") In other words double the apostrophes.
