View 2 RepliesI have this form with a bunch of input controls. I have code working that will disable them all like I want, but need to work with the if/then statement portion. Basically, it's a "History" form for patients. There's a date field for each entry, and if that date doesn't match the date you're accessing the form I want it to disable all controls so you can't edit the form. So it would have to check the current date with the date that is on the form. Then I also want to have an override button that will ask you if you want to enable all controls anyway, which I can probably figure out. There is some older VB6 code (I think) but I know nothing about VB6 or how it translates.
I think this is the portion that does what I want in VB6:
Private Sub DATE_DblClick(Cancel As Integer)
Call Setdate
Exit Sub
Dim sysDate As Date, Response
sysDate = VBA.Date
[Code] .....
How to have the program check the current date with the date in this form. From there it's probably just a simple if/then statement to fire off either sub. This date control on the form is a DateTimePicker. Maybe I just have to compare that to the system date but I still don't know what to call for that.

Working the first time with a CheckedListBox.
Question: is it possible to disable an item of the box so you can't change the value of the checkbox.
Take the following fundamental code:
Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
btnStop.Enabled = False
'Lengthy code procedure
btnStop.Enabled = True
End Sub
I've just notice that when I click on a button, and try to disable it in order to avoid the user clicking on it several times during process (or disable the entire form for that matter), the application somehow records the subsequent clicks and processes them after the button has been re-enabled. But that's not the behavior that I want at all. I just want to disable any user interaction with the button (or the form perhaps) until processing of the Button_Click event is completed. How can I do this?

View 5 RepliesThe instructions I'm following indicate that when user clicks the Add This Item menu item for a new order, the customer information should be disabled so that the state cannot be changed until the next customer.I've tried to validate that all the customer information fields are filled when user clicks Add This Item menu item. The trouble I was having was that even when you were alerted that you didn't fill one of the fields, you clicked on the message alert and then the customer fields were disabled before you could fill the empty one.
I've tried to make an if statement which checks if some are empty to alert else if they are filled then disable. This doesn't work either. I get Conversion from string "" to type 'Boolean' is not valid. I'm not advanced enough to understand this. I just know boolean means true or false or yes or no. I'm not sure the best way to handle this situation. I don't even know if locking the user out is wise since they might have wanted to correct something wrongly entered but my instructions are to validate that the fields are filled and then disable the customer information. I need to follow the instructions exactly.
This is what it looks like:
Private Sub AddThisItemToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddThisItemToolStripMenuItem.Click
