3. VC print Excel:

Call the print function of shell:

Note that a printer has been installed on the machine. The printed output is sent to the default printer. In addition, shellexcute can be used to print Excel and Word, and replace the corresponding file name.

ShellExecute (null, "print", "C: // temp // test.xls", null, null, sw_hide );

ShellExecute (null, "print", "C: // temp // test.doc", null, null, sw_hide );
