Postmessage Problem...64 bits problem

Hi,

i am using win32::guitest package since 2 weeks...

but one problem i am finding is putting the values in the PostMessage();

it takes 8 bytes as the last parameter.How to send it as the 8 bytes in perl??

8 bytes are like this ...lower 4 bytes for the x coordinate and upper 4 bytes for the y coordinate of the windows component in a gui.

I have x and y coordinate values but my question is "how to put "yx" value in perl"....if the

x=34
y=45

i want like this 4534...(34 should take 4 bytes) after that 45....how to do????
