Output double to dialog edit control

[Matthew]

Hello, I am trying to use Sendmessage from macro to output a double amount (.50) to the dialog, but it keeps rounding it up to 1
What do I need to specify instead of i to have it output it correctly - I tried d but it did not work.

Function _15_4_HOT

Code:

Copy      Help

,case WM_COMMAND goto messages2
,case WM_APP
,sel wParam
,,    case 10
,,    SetDlgItemText hDlg wParam F"{lParam%%d}"
,,,,case 22
,,,,SetDlgItemText hDlg wParam F"{lParam%%i}"

Kind Regards
Matt

;; G number will depend on numeric size and how mnay decimal places you will need

double cannot be easily passed in lParam, because lParam is too small. Easiest is to store the value in a global variable.

double+ g_456
g_456=9.5

double+ g_456
SetDlgItemText hDlg wParam F"{g_456}"

Thanks Kevin.

Not sure what I am doing wrong. The balance should be 999.50, but it is displaying as:

   

I used the example your provided for two decimal places.

Got it! Thanks very much Kevin and Gintaras, that looks like it will work.

Then use SendMessage just to update dialog, and let lParam be 0 and not used.

Or convert to string when sending message. Then don't need to change anything in dialog code.

double d=1.5
SendMessage ... ... ... F"{d}"

Oh okay, I got it to work with your first example, but that looks cleaner.

Thankyou!
