\nThe COle­Initialize<\/CODE> class is just the OLE\ncounterpart to\n\nthe CCo­Initialize<\/CODE> class we saw some time ago<\/A>.\n<\/P>\n
\nAll the program does is take the file name on the command line,\nasks the shell for the corresponding data object,\nthen puts that object onto the clipboard,\n\nerasing what was there before<\/A>.\n<\/P>\n
\nOnce the data is on the clipboard, our job is done so we exit.\n<\/P>\n
\nNo, wait!\nIf you exit while your application has data on the clipboard,\nthat clipboard data may be lost.\nThe documentation for Ole­Set­Clipboard<\/CODE>\nnotes:\n<\/P>\n
\nIf you need to leave the data on the clipboard\nafter your application is closed,\nyou should call Ole­Flush­Clipboard<\/B>\nrather than calling\nOle­Set­Clipboard<\/B>\nwith a NULL<\/B> parameter value.\n<\/BLOCKQUOTE>\n
\nTherefore, we stick in a call to\nOle­Flush­Clipboard<\/CODE>\nbefore exiting.\nThis forces any delay-rendered content to be rendered immediately,\nbecause we ain’t gonna be around to delay-render it no more.\n<\/P>\n
\nNote that the file on the command line must be fully-qualified,\nbecause we pass it straight to\nGet­UI­Object­Of­File<\/CODE>,\nwhich expects a fully-qualified path.\nFixing the program to allow relative paths (and to actually\nprint error messages and stuff) is left as an exercise,\nbecause Little Programs don’t deal with annoying details like\nerror checking and reporting.\n<\/P><\/p>\n","protected":false},"excerpt":{"rendered":"
