I wonder that when I try the searching, it gives double values of all the items on the database, like it had inputted the given data twice during insert into-event.. What's the issue?
My one doesn't work. I will begin typing a search and then the values in the data grid view will disappear and it will show just the grey background and stay like that until I close the whole program. Help please!
thanks to help me…………………

where in the world did you find datagridview1?
ColumnName not found please help
After following step by step your tutorials, kind sir, I have encountered a rather uncanny error. It appears that, after deleting the line "Dim dbDataSet As New DataTable" and declaring it as a global variable, if you press the "Load Table" button, it stores the table multiple times. I do not know for sure if this is the main issue, but after copying the line back to it's original place, everything seems to work out pretty good 🙂 Thank you for those helpfull tutorials, once again and don't take my commentary as a malitious one, please. Just wanted to point out a possible error 🙂 Have a nice day!
