实验: ProcessShellCommand自定义
对于Dialog， 是没有ProcessShellCommand的, 可以自己分析完, 存起来要用的时候再用.
对于sdi, mdi, ProcessShellCommand是要打开文档的.
CMyCommandLineInfo cmdInfo;// 自定义了命令分析类
MyParseCommandLine(cmdInfo);//自定义分析函数
// Dispatch commands specified on the command line
if (!MyProcessShellCommand(cmdInfo)) //这里怎么对应OpenNewDocument?
return FALSE;
//看见过一个sdi 的Demo, 自定义了命令行分析, 没注意. 那时我的应用是Dialog.
现在我直接按照标准的内容填写CCommandLineInfo cmdInfo,
ProcessShellCommand(cmdInfo)返回FALSE. 实际上要打开的文件名已经传过去了.
如果不判断ProcessShellCommand(cmdInfo)的返回值， 程序是可以正常打开文件.
问题找到, 打开的文件必须存在.
