关于ShellExecute使用出错

switch(choice)
{
case 1:
ShellExecute("NULL","open","G:\\11game\\11Game.exe","NULL","NULL","SW_SHOW");
break;

为什么会提示错误：“error C2664: 'ShellExecuteA' : cannot convert parameter 1 from 'char [5]' to 'struct HWND__ *'”


困扰很久了，其他几次用的都没有问题，最近写另一个软件，怎么就出问题了？
求解！ C ShellExecute
[解决办法]

ShellExecute(NULL,"open","G:\\11game\\11Game.exe",NULL,NULL,SW_SHOW)
