IsNumber() not finding number

6 posts in this topic

Please tell me what I am doing wrong.

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>


GUICreate('test')
$input = GUICtrlCreateInput('', 10, 10)
$button = GUICtrlCreateButton('TEST', 50, 50)

GUISetState(@SW_SHOW)



While 1
    
    
    $msg = GUIGetMsg()
    If $msg = $button Then
        If IsNumber(GUICtrlRead($input)) Then MsgBox('', 'Number True', GUICtrlRead($input))
    EndIf
    If $msg = $GUI_EVENT_CLOSE Then Exit
WEnd

All by me:

"Sometimes you have to go back to where you started, to get to where you want to go." 

"Everybody catches up with everyone, eventually" 

"As you teach others, you are really teaching yourself."

nitekram,

When you read an Input you always get a string, so

IsNumber(GUICtrlRead($input))

will always fail.

If you need to limit the Input to numbers, use the $ES_NUMBERS style. Look in the Help file under <GUICreateInput - style - See GUI Control Styles Appendix>.

If you need number which include negatives and decimal points, things get a bit more complicated (because you need RegExs) but it can be done. ;)

Cannot find $ES_NUMBERS ? Can you tell me what #Include I need?

Perhaps StringIs* is easier?

nitekram,

1. Open the Help file.

2. Go to the GUICtrlCreateInput page.

3. In the Parameters section look for "style"

4. Click on the link in the right-hand box - "GUI Control Styles Appendix".

5. Sixth style down: "$ES_NUMBER - 0x2000 - Accepts into the edit control only digits to be typed".

Note that you need to #include <EditConstants.au3> as it says at the top of the style listing.

; ---

Authenticity,

Good catch, I had not even thought of that. But if the Input has to be a number, I would still prefer the style.
