<br>内容：1最简单的可用WinExec<BR>The WinExec function runs the specified application. <BR><BR>This function is provided for compatibility with 16-bit Windows. Win32-based applications should use the CreateProcess function. <BR><BR>UINT WinExec(<BR> LPCSTR lpCmdLine, // address of command line<BR> UINT uCmdShow // window style for new application<BR>);<BR> <BR>2复杂一点可以用<BR>CreateProcess<BR>The CreateProcess function creates a new process and its primary thread. The new process executes the specified executable file. <BR><BR>BOOL CreateProcess(<BR> LPCTSTR lpApplicationName,<BR> // pointer to name of executable module<BR> LPTSTR lpCommandLine, // pointer to command line string<BR> LPSECURITY_ATTRIBUTES lpProcessAttributes, // process security attributes<BR> LPSECURITY_ATTRIBUTES lpThreadAttributes, // thread security attributes<BR> BOOL bInheritHandles, // handle inheritance flag<BR> DWORD dwCreationFlags, // creation flags<BR> LPVOID lpEnvironment, // pointer to new environment block<BR> LPCTSTR lpCurrentDirectory, // pointer to current directory name<BR> LPSTARTUPINFO lpStartupInfo, // pointer to STARTUPINFO<BR> LPPROCESS_INFORMATION lpProcessInformation // pointer to PROCESS_INFORMATION<BR>);<BR> <BR>3当然可以用<BR>ShellExecute ShellExecuteEx <BR><BR>

<br>内容：可是还有问题，<BR><BR>如果被调用的程序不是命令行程序，怎么传递参数？<BR><BR>比如有一个图象显示程序，现在另一个可执行程序想调用它显示图象。想调用的时候就传一个文件名过来，让前者立即显示。<BR><BR>这个怎么办？求助
