If objValue IsNot DBNull.Value Then
Dim strvalue As String = objValue.ToString().Remove(0, 6)
Integer.TryParse(strvalue, intValue)
intValue += 1
End If

DESCRIPTION
membuat warna
Example 18
Example 18.1
The Code:Dim strColor As String
Private Sub RadioButton8_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton8.CheckedChangedstrColor = 'Red'End Sub
Private Sub RadioButton7_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton7.CheckedChangedstrColor = 'Green'End Sub
Private Sub RadioYellow_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioYellow.CheckedChangedstrColor = 'Yellow'End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.ClickLabel2.Text = strColorEnd SubAlthough the user may only select one item at a time, he may make more than one selection if those items belong to different categories. For example, the user wish to choose T-shirt size and color, he needs to select one color and one size, which means one selection in each category. This is easily achieved in VB2008 by using the Groupbox control under the containers categories. After inserting the Groupbox into the form, you can proceed to insert the radio buttons into the Groupbox. Only the radio buttons inside the Groupbox are mutually exclusive, they are not mutually exclusive with the radio buttons outside the Groupbox. In Example 18.2, the users can select one color and one size of the T-shirt.Example 18.2
Dim strColor As StringDim strSize As String
Private Sub RadioButton8_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton8.CheckedChangedstrColor = 'Red'End Sub
Private Sub RadioButton7_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton7.CheckedChangedstrColor = 'Green'End Sub
Private Sub RadioYellow_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioYellow.CheckedChangedstrColor = 'Yellow'End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.ClickLabel2.Text = strColorLabel4.Text = strSizeEnd Sub
Private Sub RadioXL_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioXL.CheckedChangedstrSize = 'XL'End Sub
Private Sub RadioL_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioL.CheckedChangedstrSize = 'L'End Sub
Private Sub RadioM_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioM.CheckedChangedstrSize = 'M'End Sub
Private Sub RadioS_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioS.CheckedChangedstrSize = 'S'End Sub
