How to convert HTML into MSAcess(mdb) using VB6.0
Please Help me

There is no logical way to convert HTML code into a database. You have to explain what it is that you want to accomplish.

Sir/Madam,
I wanted to know the basic difference between shadows and overloads.
As show function is predifined.If I use show function in the following way.
Private Shadows Sub show()
End Sub
Private Overloads Sub show()
End Sub
Please illustrate the difference between them.Also In which situation , I should use shadows and overloads
Thanks and Regards

For example you have a base class:
Public Class Exhibitionist
Public Sub Show()
End Sub
End Class
and another class which derives from the Exhibitionist class:
Public Class SpecializedExhibitionist
Inherits Exhibitionist
---A)
Public Shadows Sub Show()
End Sub
---B)
Public Overload Sub Show( ByVal fullInfo As Boolean)
End Sub
End Class
- with version A) you can call
SpecializedExhibitionist_Instance.Show()
- with version B) you can call
SpecializedExhibitionist_Instance.Show()
SpecializedExhibitionist_Instance.Show( true )
Shadows means, that the Function "Show" of the base class is "cloaked"
Overloads means, that you add a new "Show" function with other parameters

Sir/Madam,
I invoked a component class into the solution.Then , wrote a line of code
Inherits system.Windows.Forms.ComboBox
This arises a following problem.
Base class System.Windows.Forms.ComboBox specified for class completereadonlycombobox cannot be different from the base class System.ComponentModel.Component of one of it's partial types
Please help.
Thanks and regards

Sounds like you have two files for this class, you need to set the derived class to be the same in both. This usually happens if you start with a control, the framework uses partial classes to hide all the autogenerated code from you

Sir/Madam,

Inhetits system.windows.Form.Combobox.
Base class System.Windows.Forms.ComboBox specified for class completereadonlycombobox cannot be different from the base class System.ComponentModel.Component of one of it's partial types
Please help.

Not sure what else I can say. Your class is defined in two files, and they are deriving from different things.

how to write code to allow only numerics
|
|
|
|
|
Place the following code in the text box's Keypress event:
Private Sub Text1_KeyPress(ByVal eventSender As System.Object, ByVal eventArgs As System.Windows.Forms.KeyPressEventArgs) Handles Text1.KeyPress
Dim KeyAscii As Short = Asc(eventArgs.KeyChar)
If KeyAscii = 13 Then KeyAscii = 0 'Prevents the system from beeping
If KeyAscii = 8 Then GoTo EventExitSub 'Allow use of backspace key
If KeyAscii < 48 Or KeyAscii > 57 Then KeyAscii = 0 'Ignore other keys
EventExitSub:
eventArgs.KeyChar = Chr(KeyAscii)
If KeyAscii = 0 Then
eventArgs.Handled = True
End If
End Sub

Eldie's strategy is correct, but it can be done with a simple function that you can then use in any other textbox also:
Public Function TrapKey(ByVal KCode As String) As Boolean<br />
If (KCode < 48 Or KCode > 57) And KCode <> 46 And KCode <> 8 And KCode <> 44 Then TrapKey = True<br />
End Function
Next in a textbox's keypress event:
Private Sub MyTextBox_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyTextBox.KeyPress<br />
e.Handled = TrapKey(Asc(e.KeyChar))<br />
End Sub
The different numbers in the function (the same ones that Eldie uses) represent different characters:
48 to 57 are numbers and the others are things like tabs, points, commas, etc. You can add or remove these extra numbers from the function depending on what you need.
have fun with it,

Hi Pradip,
What exactly is the problem? I hope you have some code that isn't working, because you can forget about someone providing you with a ready made application, if that is what you were hoping for.

Hi Pradip,
Allright then, if I understand you correctly, you are opening two different forms (f.e. FrmSalary and FrmBreakDown), and you need to pass data from each form to the same table.
Basically you can use two approaches:
1. write the data from the Salary form to the table, either direct, or via a dataset, and include some sort of record key, pass the key to the second form, for example by public variable. Then, based on the key, pass the data from the Breakdown form to the table.
2. same as approach 1, but first pass the whole thing to a temporary table, validate all data, or integrate some sort of user-approval step (the whoops step), and then copy the data to the table.
Hope this helps you,
Johan

Where have you heard the terms ? What is it you're hoping to find out ?
I've never heard of object based technology. Have you tried google ? Do you know what OO is ?

hi,
i know what is object oriented technology. i saw this in important questionnare from xyz site.
"VB.NET is object oriented where VB is object based". how can we explain this statement?
thanks,

OK - the answer then is that VB is crap. Object based is a way to make excuses for the fact that it's not OO. It knows about objects, but it's not OO, because it wasn't fully designed right. There is no design trade off, no reason to want 'object based', it's just a name for why VB sucks so much

Handle the keypress event and if char.isnumeric and char.iscontrol are both false for the char passed in on the event, set handled on the eventargs to true
