I have created a DEMO project to illustrated what I am referring to. I have a simple form, the button is set to Enabled False in the property inspector. When the user complete the form controls(fields) the button is Enabled. Everything seem to be working except the following:
When the user completes all the field, they must type twice in the MaskedTextBox for the button to be Enabled.
Even though there is no actual characters typed in the box because of it's restrictions, why do I need to type twice in the MaskedTextBox before the button is Enabled. Here is my code:
Public Class frmActivateBtn
Dim blnCheckName As Boolean, blnCheckPet As Boolean, blnCheckColor As Boolean, blnPhoneCheck As Boolean
Function turnTestButtonOn()
If blnCheckName = True And blnCheckPet = True And blnCheckColor = True And blnPhoneCheck = True

View 1 Replieshow to enable the "import" button when at least one of the checkboxes is checked.I have two buttons : "Deselect all" and "Select All" for the checking of the boxes, to import the specific files' data they want to Excel. (the files are in listbox, and the checked boxes is for selecting the files' parameters that they want to see in excel)
One option:When the user deselect all, the "import" button is suppose to be disable to prevent the user from importing the files' data parameters.
2nd option:(if i do not want to disable the import button) or show message that they have to select at least one box and at the same time, prevent the import button to work if there's no checked checkbox. So my deselect all button code :
Code:
CO2checkbox.Checked = False
NH3checkbox.Checked = False
DBcheckbox.Checked = False
[code]....
but the button still remain disabled if I click "unchecked all" button and then checked at least one box. how do I enable it?And how do i...show error message and prevent the files' data to be imported when the user click "import" when there's no checked checkbox if I choose the alternative option of using message to alert them without disabling the button and yet prevent importing of data?
PS: If I did not click "deselect all" button but click the "select all" button, the import button is enabled and working.

My program is required to remove/change the item when they select it and clcik remove. Either that or a try and catch, that will stop it from throwing errors when there is no item selected.
