Android Question B4Xpreference Dialog

[bluedude]

Hi,

How can I disable the ok or cancel button during launch of the dialog?

You need to provide more information on what you are trying to do.

If you want to validate the data then use the IsValid event.

There is not more information, I just want to disable one of the buttons based on some logic. I understand validation but that's not what I'm referring to.

 

[Erel]

You can pass empty strings to the Show method to remove buttons.

Cool, thanks!

Hi,

Smal question about IsValid event. I want to do a httpjob to validate. However, this can only work when using Resumablesub in the http sub that I use. This however does not work with the IsValid event because it needs to be a Boolean while B4A asks me to change it to Resumablesub.

All should happen when the dialog is open. Otherwise I have to open and close the dialog all the time when a value is not valid.

Any suggestions?

You can return any Value in your resumeable sub. Even a boolean.

Resumeable subs that return a value.

Sub Button1_Click
   Wait For(Sum(1, 2)) Complete (Result As Int)
   Log("result: " & Result)
   Log("after sum")
End Sub

Sub Sum(a As Int, b As Int) As ResumableSub
   Sleep(100)
   Log(a + b)
   Return a + b
End Sub

For ANY other question you should start a new thread. NEVER post multiple question in the same thread.

That's not the issue or question, I understand that. However, the IsValid event cannot be changed/is not supporting ResumableSub it seems.

The IsValid event is not called with Wait For so it cannot be a resumable sub. You can use the source code and modify it to be called with Wait For.
