help 'formatting' an edit box

Recommended Posts


I have a small gui with an edit box and a few buttons, the buttons are '0.2' '0.5' & '1'.

So when I click 0.2 it will display 0.2 in the edit box, if I click it again it will add another 0.2 and display 0.4 in the edit box etc.

This is working fine, here is my main function so you can see...

Func _Function()
$ReadEnteredControl = GuiCtrlRead($INPUT_ENTERED)
$Add20toEntered = ($ReadEnteredControl +"0.20")
GUICtrlSetData($INPUT_ENTERED, $Add20toEntered)

where $INPUT_ENTERED is the variable name of my edit box.

This works fine but how can I format the edit box to display 0.20 (so 2 decimal places instead of 1) as at the moment it only shows 1 digit after the .

Firstly, I strongly recommend that you convert the current content of the edit to, and write the value to be added in, number format when performing the addition - use Number to do this. Letting AutoIt decide the conversion for itself when carrying out mathematical operations can cause problems - particularly comparisons. ;)

Then when you rewrite the result, use StringFormat with the following "format control":

$ReadEnteredControl = GuiCtrlRead($INPUT_ENTERED)
$Add20toEntered = Number($ReadEnteredControl) + 0.20)
GUICtrlSetData($INPUT_ENTERED, StringFormat("%.2f", $Add20toEntered))
That way you always get 2 decimal places. :)

Thats excellent thanks, works perfectly -  I had to remove the ) after the 0.20 though 'cos I got a bracket error as there wasno opening bracket for it.

Thanks a lot
