This was brought up yesterday.
You do NOT modify the controls on Form1 from Form2. Form2 shouldn't know anything about Form1, nor should it care. All it should care about is the data that it's supposed to manipulate.
If you're showing Form2 using ShowDialog(), then Form1 creates an instance of Form2 and waits for Form2 to be dismissed. Form2 exposes any data that it should as public properties or as some data object. Form1, when it gets control back, looks at the data in Form2 properties or in the data object that it modified and then modifies its own controls accordingly.

What did you expect you were going to get?? Something that does it for you automatically??
This article[^] is about as generic as you're going to get.

try to check the value of your txtbox... maybe it is getting a null string or space that is why your database is returning all the data...

Hi,
Dim bDel as Boolean
Dim strSource as string
Dim strTarget as string
...
bDel = ...
If File.Exist(strTarget) Then
If bDel = True Then
File.Delete(strTarget)
Else
MsgBox ("File Already Exist!")
Exit Sub
End If
End If
File.Copy(strSource, strtarget)

SELECT * FROM Persons
WHERE FirstName LIKE '%la%'

plz help

Hi,
You could simply use the following:
Dim strSQL as STring
strSQL = "SELECT * FROM Persons WHERE FirstName LIKE '%" & TextBox1.Text & "%'"
...
But this is not a secure way, SQL Injection could be possible here!

As the previous poster mentioned, the solution given is susceptable to SQL Injection Attacks. You should learn to defend yourself from them. Please read SQL Injection Attacks and Tips on How to Prevent Them[^]

Hi, I get the error message '(' expected on the line Dim _buf As Byte() = CByte.parse(_cmd.ExecuteScalar()) . I also get the error message saying that _buf is undefined on the line Response.BinaryWrite(_buf)in the following code.
Try
_con.Open()
Dim _cmd As SqlCommand = _con.CreateCommand()
_cmd.CommandText = "select logo from" + " pub_info where pub_id='" + id + "'"
Dim _buf As Byte() = CByte.parse(_cmd.ExecuteScalar())
'stream it back in the HTTP response
Response.BinaryWrite(_buf)
Catch
Finally
_con.Close()
End Try
I tried enclosing _cmd.ExecuteScalar() with one more ellipsis but that didn't help. I also tried changing Dim _buf As Byte() to
Dim _buf() As Byte and
Dim _buf As Byte.
Neither of them solved the problem. Please help me determine what is causing the error. Thank you in advance for your help.

It should be:
Dim _buf As Byte() = CByte(parse(_cmd.ExecuteScalar())

I see several problems with this code snippet:
"select logo from" + " pub_info where pub_id='" + id + "'" Why are you concatenating "select logo from" and " pub_info where pub_id=" ??
This is a better approach:
string.Format("select logo from pub_info where pub_id='{0}'", id) Only one string is declared and no concatenation takes place.
CByte() attempts a conversion from something to a Byte, not an array of bytes. If the scaler execution is returning an array of bytes then with option strict off you should be able to just assign it. If you want to program decently and switch option strict on then the following would assign it:
Dim _buf As Byte() = DirectCast(_cmd.ExecuteScaler(), Byte()) If you get an invalid type / cast exception then the result of the query is not a byte array.
Finally I see a Finally clause in use to close the connection, which is great. But why is there an empty Catch ? It's not needed.
Hope this helps.

This is a better approach:
string.Format("select logo from pub_info where pub_id='{0}'", id)
That will work, but it is still subject to SQL injection attacks.

True, assuming you pass the value from the UI to the data layer unaltered.
So either use a sproc or:
StringBuilder sb = New StringBuilder(id)
sb.Replace("\", "\\")
sb.Replace("'", "\'")
...
string.Format("select logo from pub_info where pub_id='{0}' ESCAPE '\'", sb.ToString())
Something like that will work I believe.
