C++中调用.EXE一下

C++中调用.EXE高手指点一下
用C++编写一个调用.exe文件来处理图片的程序  
该.exe文件处理程序需要用convert.exe   a.jpg   -compress   b.tiff   命令  
ShellExecute(handle,   "explore ",   path_to_folder,   NULL,   NULL,   SW_SHOWNORMAL);函数能写这个程序么  

include   <shellapi.h>  

#include   <iostream>  
using   namespace   std;  

int   main()  
{  
ShellExecute(handle, "open ",   "C:\\Program   Files\\ImageMagick-6.2.7-Q16\\convert.exe ",   NULL,  
NULL,   SW_SHOW   );  
system( "convert.exe   a.jpg   -compress   none   b.tiff ");  

cout < <   "我的功能是运行一个记事本. "   < <endl;  
return   0;  
}  
这样对么   我怎么运行不出来啊   错在哪里   帮改一下

[解决办法]
#include <windows.h>

简单啊
CreateProcess(_T( "C:\\Program Files\\ImageMagick-6.2.7-Q16\\convert.exe "),
_T( "a.jpg -compress b.tiff "),
LPSECURITY_ATTRIBUTES lpProcessAttributes,\\NULL
LPSECURITY_ATTRIBUTES lpThreadAttributes,\\NULL
BOOL bInheritHandles,\\ true or false
DWORD dwCreationFlags,\\ 其他参数见sdk或msdn
LPVOID lpEnvironment,
LPCTSTR lpCurrentDirectory,
LPSTARTUPINFO lpStartupInfo,
LPPROCESS_INFORMATION lpProcessInformation
)

[解决办法]
#include <string>
#include <windows.h>

using namespace std;

int main(int argc, char* argv[])
{
PROCESS_INFORMATION ProcessInfo;
STARTUPINFO StartupInfo={0};
string strCmd;

strCmd = "C:\\Program Files\\ImageMagick-6.2.7-Q16\\convert.exe a.jpg -compress none b.tiff ";

CreateProcess(NULL,
(char*)strCmd.c_str(),
NULL,
NULL,
FALSE,
CREATE_NEW_CONSOLE,
NULL,
NULL,
&StartupInfo,
&ProcessInfo);


return 0;
}
