There's no equivalent control in VB6. You'd have to write it yourself. You can use the Regular Expression library that comes as part of Windows Scripting to make your life a bit easier. There's all kinds of RegEx strings that'll validate an email address for you.
I don't have any example code, because I stopped using VB6 when .NET was in Beta...

- In such case u can use the .NET 'RegularExpression' in VB6.0 through the COM Interop.
- Using the 'RCW' the .NET Namespaces can be used in VB6 also.

hi friends,
My problem is how can i use my barcode judget using PS2 connection.? my project built in Visual Basic 6. Please help me.

Normally, these things are attached in-line with the keyboard, so any output that comes from the barcode scanner is treated exactly like you typed it at the keyboard. There's really nothing to do...

Barcode scanners usually come as either Serial connection or keyboard wedge. If yours has a ps2 connection it will be of the keyboard wedge type. All the ones i have seen require some sort of setup which is normally done by scanning codes from the book that comes with it (Setting character sets and leading character sort of thing).
What this means is that whenever you scan a barcode the output should appear in whatever application you have open eg notepad, word or even outlook. This means that what you need to do is capture the string into a textbox so typically you could put a mesaage on screen sating "Scan Product" and set the focus to an invisible textbox ready to accept the input (can be invisible if you want but it must have focus).
You will need the setup books or you wont be able to set the character set or set a character to prefix the actual barcode so your application knows there is a barcode.
In general keyboard wedge scanners are pretty easy to set up and use so read the documentation with the device and you should have no problems.

Here is a combox control in a winform.
I want to select an item of it by code.
How to do ?
Thanks!

you have the choice between the following :
MyComboBox.SelectedIndex = 2 'to select the 3rd item in the list
MyComboBox.SelectedItem = AnObject
MyComboBox.SelectedValue = AnotherObject
TOXCCT >>> GEII power
[toxcct][VisualCalc]
|
|
|
|
|
I want to initial the value when loading a winform.
Actually , I do not know the Index of then combobox.
I only know the ID and the Name of the combobox item.

I think this code does your request.
ComboBox1.SelectedIndex = 2
The other properties can not be used as a target of assignment
Ex:
ComboBox1.SelectedValue.ToString() = "choice2" 'Items of ComboBox1 :choice1,choice2..etc..

are you sure you can assign a constant that comes from ToString() ???
i don't believe.
Moreover, ValueMember does not contain only strings...

Here what i wrote:

Ex: (example for the expression at the upperside)
ComboBox1.SelectedValue.ToString() = "choice2" 'Items of ComboBox1 :choice1,choice2..etc..

yes but, why don't you write
ComboBox1.SelectedValue = "choice2"
instead of
ComboBox1.SelectedValue<font color=red>.ToString()</font> = "choice2"
TOXCCT >>> GEII power

I think it may be a bug of vs.net 2005 beta 1.
|
|
|
|
|
I hope this will help you
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Dim list As New ArrayList
With list
.Add("John")
.Add("James")
.Add("Jack")
.Add("Jimy")
.Add("Jombo")
.Add("Jimbo")
End With
End Sub

I use console.write("xxx") in my project.
But there is nothing in local output.
How to find the text?
vs.net 2005 beta 1.
|
|
|
|
|
The Output tab, although it's most common to use Trace.Write(xxx) to debug code.
|
|
|
|
|
There is some internal information in the output tab.
However, there is nothing about my output.
|
|
|
|
|
Console.Write() as its name says, writes into a cosole window.
the Visual Studio output window displays some debug informations, as it has been said to you already...
if you want to write text there anyway, replace your Console.Write() with Trace.Write()

|
|
|
|
The Trace.write() do not show text in output tab ,too.
|
|
|
|
|
|
There is only debug mode in vs.net 2005 beta 1.
|
|
|
|
|
don't know if you've solved this but use
debug.write("string")
then look in local
