问题 I create one page workbook files in eclipse and need to open the print dialog box and print these files off.

问题 I need to print a photo (.jpg) from the command line in Windows 7. I have tried using lpr to no success, and found methods for Windows XP like the following: rundll32 shimgvw.dll ImageView_PrintTo /pt myPhoto.jpg "myPrinter" This doesn't work (not surprising), and my hours of Googling has turned up nothing else.

问题 I am using the following code to print a page within my application... <html><body onload=""window.print();"">" sHtmlBody = sHtmlBody & "<body>" The window.print() is working fine.
