get_last_error

audio_form object

This method will return the error code for the last operation.

int get_last_error()

Parameters:
None.

Return value:
The Error code of the previous operation.

Remarks:
Every time a method is called, the error is reset. Therefore you must call the get_last_error method directly after the call to the method you are checking.

Example:

// Make a simple form with a few buttons and cause a deliberate error.

#include "form.bgt"

audio_form form;

void main()
{
form.create_window("Example Form", true);
int ok=form.create_button("OK");
int cancel=form.create_button("E&xit");
while(true)
{
form.monitor();
wait(5);
if(form.is_pressed(ok))
{
form.get_text(ok);
alert("Information", "The error code is "+form.get_last_error());
exit();
}
if(form.is_pressed(cancel))
{
exit();
}
if((key_down(KEY_LMENU))&&(key_pressed(KEY_F4)))
{
exit();
}
}
}
