Ok Ganesh listen up, The printer resolution is far more than screen's resolution.
So you need to calculate the number of times Printer resolution is greater than Screen's
So get printers Resolution use
int xPrnRes = GetDeviceCaps(hPrinterDC,LOGPIXELSX);
int yPrnRes = GetDeviceCaps(hPrinterDC,LOGPIXELSY);
Get Screens Res
int xScrnRes = GetDeviceCaps(hScreenDC,LOGPIXELSX);
int yScrnRes = GetDeviceCaps(hScreenDC,LOGPIXELSY);
Get Ratio
double ratio_x = (double)xPrnRes/(double)xScrnRes;
double ratio_y = (double)yPrnRes/(double)yScrnRes;
ok so if you have an image of say 100x100 px on screen and you want to print it the destination image will be of 100*ratio_x and 100*ratio_y
so instead of using BitBlt you have to use StretchBlt to stretch the Bitmap
You know you're obsessed with computer graphics when you're outside and you look up at the trees and think, "Wow! That's spectacular resolution!"

1>.how to get the item handle by its name/string?
->I guess you cannot, what if two nodes having same name? Instead try using GetItem and GetNextitem function.
2>.how to know the item stay at which lay? for example: Lay1Item1 stay at lay 1, root is 0,BB is lay 2
-> SetItemData may help.

Silly question, had a lok in the MSDN but could not find any thing that satisfied my curiosity, how long can a command line be? I´m asking because I am passing a path to a file,plus an SQL query to an external process (using create process), so can I expect any problems regarding a very long SQL query...
Thanks in advance
Phil
bum... and I thought I´d got rid of all the bugs

from stdlib.h on VS.NET
/*
* Sizes for buffers used by the _makepath() and _splitpath() functions.
* note that the sizes include space for 0-terminator
*/
#define _MAX_PATH 260 /* max. length of full pathname */
#define _MAX_DRIVE 3 /* max. length of drive component */
#define _MAX_DIR 256 /* max. length of path component */
#define _MAX_FNAME 256 /* max. length of file name component */
#define _MAX_EXT 256 /* max. length of extension component */
Hope these help
