在VC程序中调用exe文件或者批处理文件方法总结

在VC程序中调用exe文件或者批处理文件的方法：

一、使用system函数。

该函数可以直接使用，调用exe程序或者bat批处理程序

例如：CString strCommand("d:\\test.bat");

system(strCommand);

二、使用ShellExecute函数

该函数可以将调用的窗口隐藏或者显示。

HINSTANCE ShellExecute( HWND hwnd,

LPCTSTR lpOperation,

LPCTSTR lpFile,

LPCTSTR lpParameters,

LPCTSTR lpDirectory,

INT nShowCmd

);

三、使用CreateProcess函数

std::string strCommand = strApp + "\\PerDecodeX2ap.exe";

PROCESS_INFORMATION pi;

STARTUPINFO si;

//初始化变量

memset(&si,0,sizeof(si));

si.cb=sizeof(si);

si.wShowWindow = SW_HIDE;

si.dwFlags = STARTF_USESHOWWINDOW;

char buff[256];

sprintf(buff,"%s",strCommand.c_str());

BOOL fRet=CreateProcess(NULL,

buff,

NULL,

NULL,

FALSE,

NORMAL_PRIORITY_CLASS|CREATE_NO_WINDOW,

NULL,

NULL,

&si,

&pi);

if (!fRet)

{

LPVOID lpMsgBuf;

FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |

FORMAT_MESSAGE_FROM_SYSTEM |

FORMAT_MESSAGE_IGNORE_INSERTS,

NULL,

GetLastError(),

MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language

(LPTSTR) &lpMsgBuf,

0,

NULL );

AfxMessageBox( (LPCTSTR)lpMsgBuf);

return FALSE;

}

四、使用如下封装好的函数（自己写的），尝试各种方法去启动可执行程序

CommandExecuter(const char *szAppName, const char *szCmd)

{

char szWorkPath[256] = {0};

char szCommand[256] = {0};

int j = 0;

//从配置文件中取参数

STARTUPINFO si = {0};

PROCESS_INFORMATION pi = {0};

si.cb = sizeof(si);

if ( szAppName != NULL && strlen(szAppName) > 0 )

{

memset( szWorkPath, 0, 256 );

GetSystemDirectory(szWorkPath, 256);

szWorkPath[3] = '\0';

strcat(szWorkPath, "Program Files\\");

strcat(szWorkPath, szAppName);

if(_access(szWorkPath, strlen(szWorkPath)) == -1)

{

strcpy(szWorkPath, szAppName);

}//if(_access(szWorkPath, strlen(szWorkPath)) == -1)

strcat(szWorkPath, " ");

strcat(szWorkPath, szCmd);

if ( CreateProcess( NULL,

(char *)szWorkPath,

NULL,

NULL,

FALSE,

0,

NULL,

NULL,

&si,

&pi ) )

{

CloseHandle( pi.hThread );

CloseHandle( pi.hProcess );

return;

}

if ( CreateProcess( szAppName,

(LPSTR)szCmd,

NULL,

NULL,

FALSE,

0,

NULL,

NULL,

&si,

&pi ) )

{

CloseHandle( pi.hThread );

CloseHandle( pi.hProcess );

return;

}

if ( (int)ShellExecute ( NULL,

NULL,

(LPCSTR)szWorkPath,

NULL,

NULL,

SW_SHOW ) > 32 )

{

// 启动成功了

return;

}

if ( (int)ShellExecute( NULL,

NULL,

szAppName,

(LPCSTR)szCmd,

NULL,

SW_SHOW ) > 32 )

{

// 启动成功了

return;

}

}//if ( szAppName != NULL && strlen(szAppName) > 0 )

else

{

if ( CreateProcess(NULL, (char *)szCmd, NULL, NULL, FALSE,

0, NULL, NULL, &si, &pi) )

{

CloseHandle( pi.hThread );

CloseHandle( pi.hProcess );

return;

}//if ( CreateProcess(NULL, (char *)szCmd, NULL, NULL,

FALSE, 0, NULL, NULL, &si, &pi) )

ShellExecute ( NULL, NULL, (LPCSTR)szCmd, NULL, NULL,

SW_SHOW );

}

}
