Dialog if examples

You can use conditional IF statements to control most of the dialog elements and commands inside a dialog window.

INPUT example with IF statement

first_var=1
if first_var=1 then INPUT 65,  017, 70, 24, w1, 10

will only show the input box when first_var = 1

first_var=1
second_var=1
if first_var=1 then if second_var=1 then INPUT 65,  017, 70, 24, w1, 10

will only show the input box when first_var = 1 and second_var = 1

CHECK example with IF statement

first_var=1
if first_var=1 then CHECK 070,  044, 070, 24, "Cross", dir1,  0

will only show the check box when first_var = 1

first_var=1
second_var=1
if first_var=1 then if second_var=1 then CHECK 070,  044, 070, 24, "Cross", dir1,  0

will only show the check box when first_var = 1 and second_var = 1

IMAGE example with IF statement

is_inch=1
if is_inch=1 then IMAGE 265, 35, 100, 100, "inch.bmp"
if is_inch=0 then IMAGE 265, 35, 100, 100, "metric.bmp"

when the variable is_inch=1, show image "inch.bmp", if variable is_inch=0 then show image "metric.bmp"

IMAGE example with IF statement and using ON_EVENT

is_inch=1
if is_inch=1 then IMAGE 265, 35, 100, 100, "inch.bmp"
if is_inch=0 then IMAGE 265, 35, 100, 100, "metric.bmp"
ON_EVENT radio1, image1,show

Will display image1 only if radio1 button is selected, image1 will hold either "inch.bmp" or "metric.bmp" based on if the variable is_inch is 0 or 1
