about general report function

[linbl352]

hi,

Does anybody have an idea about how to write a general report generator module?

Right now, I can create a report file by coding the specific position on a page. codes like following:
print_textbox(F ile, Page, 100, 100, 200, 300, "Hello");
It means It prints the string "Hello" at the location starts from (100, 100) to(200,300 ).
So, If I want to print the text at another location, I have to change the numberic data one by one. That is repeated work.
Does it have any solution for it to reduce the times of modifying numberic data?

Thanks

Not without more information. I think you description of what you already have is too limited, you presumably don't just print "hello" each time. Post a larger section of pseudo code.

In general if you have to change a output you are always going to have to provide a different input (unless you code is envoking undefine behaviour in which case just changing you hat might well do the trick).

If, as I suspect you are printing a report with multiple times and you want to be able to shift all the items down 1 line (say) but only have to make 1 change then you should create a function that prints all items relative to a supplied orign, then to alter the position of everything all you need to do is alter the origin supplied to the function.

Instead of

print_textbox(File, Page, 100, 100, 200, 300, "Hello");
print_textbox(File, Page, 100, 100, 300, 400, "World");
print_textbox(File, Page, 100, 100, 400, 500, "Wibble Banana Jellyfish");
 

try

 
print_report( origin_x, origin_y )
    print_textbox(File, Page, origin_x+0, origin_x+0, origin_y+0, origin_y+100, "Hello");
    print_textbox(File, Page, origin_x+0, origin_x+0, origin_y+0, origin_y+100, "World");
    print_textbox(File, Page, origin_x+0, origin_x+0, origin_y+0, origin_y+100, "Wibble Banana Jellyfish");
}
 
print_report( 100, 200 )

yes. this is a solution of that problem.
But, if I change the orientation style from portrait to landscape when I print the report, I have to change the parameters in function print_report(10 0,200). If there are many print_report(10 0,200) calls, It will cost much time on doing that multiple job.
So, What I am looking for is automatically adjusting the postion according to the paper's size( width and height )
