VB 6 need help

unsa.on pagcheck if naay blank or empty sa database?

you can do it via recordset object

e.g.

if trim(recordset.Fields("IDNo"))="" then
msgbox "Empty or NULL"
end if

OR

do it in sql statement

recordset.open "SELECT * FROM table WHERE field1 IS NULL",activeconnection
if NOT recordset.EOF then
msgbox "Empty or NULL"
end if


I hope I help you with a simple solution

bro naa ko prob gamay about sa vb, ngano mo "object required" mani sya bro kung magbutang ko txtidno.setfocus sa formload?any idea?....

Private Sub Form_Activate()
'Ari ibutang imong set focus sa txtbox
End Sub

i'll try this. ako man gud ibutang sa module kay gamiton nako sa update ang clear. mas easier kung ibutang sa form.

Kung gusto ka ibutang sa module ang clear, d ay gamayng function para ana:

Public Sub ClearDataField(frm As Form)
On Error Resume Next
Dim ctrl As Control
For Each ctrl In frm
If TypeOf ctrl Is VB.TextBox Then
ctrl.DataField = 0
End If

Next
End Sub

Inig tawag nimo sa function: ClearDataField Me

Me is the form.

Happy Coding!

unsa code for mo auto caps ang input?

how to use try catch if naay mo error?

unsa code for mo auto caps ang input?

Create the handler for the Keypress event of the control, assuming it's a Textbox, you can manipulate the KeyAscii as you please, e.g.

private sub myTextBox_Keypress(KeyAscii as integer)
   KeyAscii = Asc(UCase$(Chr$(KeyAscii))) ' Untested code for upcasing a character
end sub

how to use try catch if naay mo error?

If this is still VB6, only On Error statements that are available. You can do something like:

function myFunc()
on error goto myErrorCatcher

    ' some code here
myFuncExit:
    exit function

myErrorCatcher:
    ' apply logic on what to do with each error, possibly display it to the User
    ' if err = 2051 then etc.
    MsgBox "[" & err & "] - " & err.Description

    ' you can use Resume, Resume Next, Resume <goto_pointer>
    ' e.g.
    Resume myFuncExit
end function
