ACTION ( cFile:=cGetFile( "*.*", "Select a file" ),;
iif(Image_size(cFile), MsgAlert( "Dimensione non consentita" ),;
cTabImage:= relativePath( cFile )+cFileNoPath( cFile )) ,;
aGet[3]:refresh())


....

FUNCTION Image_size(cImgname)
LOCAL oImage
local lreturn :=.f.
DEFINE IMAGE oImage FILENAME cImgname
cWidth := ALLTRIM(STR(oImage:nWidth()))
cHeight := ALLTRIM(STR(oImage:nHeight()))
oImage:End()

IF val(cHeight) >16 .and. val(cWidth) >16
MsgAlert( "Height : " + cHeight + CRLF + "Width : " + cWidth, "Image-size" )
lreturn :=.t.
else
lreturn :=.f.

Maybe missing ?
FREEIMAGE.DLL is needed to display other Formats.

#include "FiveWin.ch"
#include "Image.ch"

no uwe
if the oimage is closed and before he not saved the values of sizes of image then he cannot show these value
the error is on image_size() function or on the get there is an error

I made and here run ok:

@ 40, 10 SAY "Image:" OF oDlg SIZE 21, 8 PIXEL
@ 38, 39 GET aGet[3] var cTabImage OF oDlg SIZE 145, 12 PIXEL



@ 38, 186 BUTTON oBtnSel PROMPT "=>" OF oDlg PIXEL SIZE 10, 12 ;
ACTION ( cFile:=cGetFile( "*.*", "Select a file" ),;
iif(Image_size(cFile), MsgAlert( "Immagine non consentita.@@@ Sono consentite solo le immagini@@@ con risoluzione 16X16 con formato BITMAP" ),;
cTabImage:= relativePath( cFile )+cFileNoPath( cFile )) ,;
aGet[3]:refresh())




FUNCTION Image_size(cImgname)
LOCAL oImage
local lreturn :=.f.
DEFINE IMAGE oImage FILENAME cImgname
cWidth := ALLTRIM(STR(oImage:nWidth()))
cHeight := ALLTRIM(STR(oImage:nHeight()))
oImage:End()

IF val(cHeight) >16 .and. val(cWidth) >16
MsgAlert( "Le misure dell'immagine selezionata sono:@@@ Altezza => " + cHeight +;
CRLF + "Larghezza => " + cWidth, "Dimensioni immagine selezionata" )
lreturn :=.t.

OR GOOD THIS:



@ 38, 186 BUTTON oBtnSel PROMPT "=>" OF oDlg PIXEL SIZE 10, 12 ;
ACTION ( cFile:=cGetFile( "*.*", "Select a file" ),;
iif(Image_size(cFile,16,16), MsgAlert( "Immagine non consentita.@@@ Sono consentite solo le immagini@@@ con risoluzione 16X16 con formato BITMAP" ),;
cTabImage:= relativePath( cFile )+cFileNoPath( cFile )) ,;
aGet[3]:refresh())



//USAGE Image_size(NAME OF IMAGE,HEIGHT OF IMAGE , WITH OF IMAGE)

FUNCTION Image_size(cImgname,XF,yf)
LOCAL oImage
local lreturn :=.f.
DEFAULT XF:= 16,;
Yf:=16
DEFINE IMAGE oImage FILENAME cImgname
cWidth := ALLTRIM(STR(oImage:nWidth()))
cHeight := ALLTRIM(STR(oImage:nHeight()))
oImage:End()

IF val(cHeight) >XF .and. val(cWidth) >YF
MsgAlert( "Le misure dell'immagine selezionata sono:@@@ Altezza => " + cHeight +;
CRLF + "Larghezza => " + cWidth, "Dimensioni immagine selezionata" )
lreturn :=.t.
else
lreturn :=.f.
endif
RETURN lreturn

Thanks Silvio

I tried your code.

But it does not show the picture in the button, something perhaps like:

oBtnSel:SetFile( cImgName )
