2. find where i can use TwipsPerPixelX(Y), in VB.net it is no longer to support this function(s). but i find it in msdn 2003 (the URL is ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.2052/vbcon/html/vbup2038.htm)
it is written that we can use TwipsPerPixelX in the name space VB6. ie. VB6.TwipsPerPixelX, i tried,but it cannot recognize the VB6 namespace. then i write the code in the VB6, and let VB.net change it automatically, i can see "VB6" in the code in use. i don't know the reason.
do you have some ideas? thx.
