再问有关外部程序的调用？

[billfranck]

HANDLE hProcess;
STARTUPINFO startInfo;
ZeroMemory(&startInfo,sizeof(startInfo));
startInfo.cb = sizeof(STARTUPINFO);
startInfo.lpReserved = NULL;
startInfo.lpTitle = NULL;
startInfo.lpDesktop = NULL;
startInfo.dwX = 0;
startInfo.dwY = 0;
startInfo.dwXSize = 0;
startInfo.dwYSize = 0;
startInfo.dwXCountChars = 0;
startInfo.dwYCountChars = 0;
startInfo.dwFlags = STARTF_USESTDHANDLES;
startInfo.wShowWindow = 0;
startInfo.lpReserved2 = NULL;
startInfo.cbReserved2 = 0;
startInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
startInfo.hStdOutput = GetStdHandle(STD_OUTPUT_HANDLE);
startInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);
int soundserve;
PROCESS_INFORMATION procinfoserve;
ZeroMemory(&procinfoserve,sizeof(procinfoserve));
soundserve=CreateProcess(NULL,"..\..\CCIR\EPDM.EXE",NULL,NULL,TRUE,0,NULL,NULL,&startInfo,&procinfoserve);
if (soundserve>0)
{
DWORD dPids = procinfoserve.dwProcessId;
hProcess = OpenProcess(PROCESS_ALL_ACCESS,FALSE,dPids);
}
方法一（上）


方法二（下）



//ShellExecute(NULL, "open", "你的文件,带路径", NULL, NULL, SW_NORMAL);
//ShellExecute("open", NULL, "EPDM.EXE", NULL, "..\..\CCIR", SW_SHOWNORMAL);
*/
ShellExecute(NULL, "open", "D:\PROGRAM\CCIR\EPDM.EXE", NULL, NULL, SW_SHOWNORMAL);

}


为什么都没有反应？？

[billfranck]

以上方法都是热心人提供可我太笨了，不知怎么用？
嵌入我的程序都没有反应？
不知为何请指教！

[Lonelywolf1899]

方法2比较简单，"D:\PROGRAM\CCIR\EPDM.EXE", 换成你要执行的程序的路径就好了。
也可以用WinExec()，参数和ShellExecute差不多的。

[3996906]

代码实在看不出来问题~~~~~~~~~~~

[int64]

Look：

AnsiString PathName;
PathName = ExtractFileDir(Application->ExeName); ///得到本可执行文件 的路径
PathName = PathName + "\\FFSL.exe";
HINSTANCE hInst = ShellExecute(GetDesktopWindow(),
"open",
PathName.c_str(),
NULL,
NULL,
SW_SHOWNORMAL);
if (hInst <= (HINSTANCE)32)
Application->MessageBox("程序打开失败!","错误",MB_OK);

[铖邑]

CreateProcess(NULL,"..\..\CCIR\EPDM.EXE","EPDM",NULL,TRUE,0,NULL,"..\..\CCIR",&startInfo,&procinfoserve);

[constantine]

怎么看都是我的代码，哈哈！我这里可以，你那里有问题？？

有个可能，你的路进有错误，你加多一句判断，看看你要打开的文件在不在

[wenyongjie]

String addpath=ExtractFilePath(Application->ExeName)+filename;//打开指定路径的文件名
ShellExecute(Application->Handle,"Open",addpath.c_str(),NULL,NULL,SW_SHOW);

[Maconel]

很正常啊，就是路径里应该是
“D:\\PROGRAM\\CCIR\\EPDM.EXE”
要用\\来代替\

[3996906]

我靠
怎么就没注意他写的单“\”呢？

[billfranck]

AnsiString PathName;
PathName = ExtractFileDir(Application->ExeName); ///得到本可执行文件 的路径
PathName = PathName + "..\..\CCIR\EPDM.EXE";
HINSTANCE hInst = ShellExecute(GetDesktopWindow(),
"open",
PathName.c_str(),
NULL,
NULL,
SW_SHOWNORMAL);
if (hInst <= (HINSTANCE)32)
Application->MessageBox("程序打开失败!","错误",MB_OK);


为什么总是“程序打开失败”
我的可执行文件就是EPDM.EXE 路径也对为什么还是动行不起来

[billfranck]

HANDLE hProcess;
STARTUPINFO startInfo;
ZeroMemory(&startInfo,sizeof(startInfo));
startInfo.cb = sizeof(STARTUPINFO);
startInfo.lpReserved = NULL;
startInfo.lpTitle = NULL;
startInfo.lpDesktop = NULL;
startInfo.dwX = 0;
startInfo.dwY = 0;
startInfo.dwXSize = 0;
startInfo.dwYSize = 0;
startInfo.dwXCountChars = 0;
startInfo.dwYCountChars = 0;
startInfo.dwFlags = STARTF_USESTDHANDLES;
startInfo.wShowWindow = 0;
startInfo.lpReserved2 = NULL;
startInfo.cbReserved2 = 0;
startInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
startInfo.hStdOutput = GetStdHandle(STD_OUTPUT_HANDLE);
startInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);
int soundserve;
PROCESS_INFORMATION procinfoserve;
ZeroMemory(&procinfoserve,sizeof(procinfoserve));
soundserve=CreateProcess(NULL,"..\\..\\CCIR\\EPDM.EXE","EPDM",NULL,TRUE,0,NULL,"..\\..\\CCIR",&startInfo,&procinfoserve);

if (soundserve>0)
{
DWORD dPids = procinfoserve.dwProcessId;
hProcess = OpenProcess(PROCESS_ALL_ACCESS,FALSE,dPids);
}



提示:1. cannot convert 'char *' to '_SECURITY_ATTRIBUTES"
2.type mismatch in parameter 'lpProcessAttibutes' (wanted '_SECURITY_ATTRIBUTES *' got 'char *')
3.'hProcess' is assigned a value that is never used


请指教

STARTUPINFO startInfo;
ZeroMemory(&startInfo,sizeof(startInfo));
startInfo.cb = sizeof(STARTUPINFO);
startInfo.lpReserved = NULL;
startInfo.lpTitle = NULL;
startInfo.lpDesktop = NULL;
startInfo.dwX = 0;
startInfo.dwY = 0;
startInfo.dwXSize = 0;
startInfo.dwYSize = 0;
startInfo.dwXCountChars = 0;
startInfo.dwYCountChars = 0;
startInfo.dwFlags = STARTF_USESTDHANDLES;
startInfo.wShowWindow = 0;
startInfo.lpReserved2 = NULL;
startInfo.cbReserved2 = 0;
startInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
startInfo.hStdOutput = GetStdHandle(STD_OUTPUT_HANDLE);
startInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);
int soundserve;
PROCESS_INFORMATION procinfoserve;
ZeroMemory(&procinfoserve,sizeof(procinfoserve));
soundserve=CreateProcess(NULL,"..\\..\\CCIR\\EPDM.EXE",NULL,NULL,TRUE,0,NULL,NULL,&startInfo,&procinfoserve);
if (soundserve>0)
{
DWORD dPids = procinfoserve.dwProcessId;
hserveProcess =OpenProcess(PROCESS_ALL_ACCESS,FALSE,dPids);
}

试试看，

[constantine]

hserveProcess =OpenProcess(PROCESS_ALL_ACCESS,FALSE,dPids);
改为hProcess=OpenProcess(PROCESS_ALL_ACCESS,FALSE,dPids);
定义全局变量HANDLE hProcess;//这样你才能关闭啊

if(FileExists("..\\..\\CCIR\\EPDM.EXE"))
ShowMessage("EPDM.EXE");
CreateProcess（.........）
看看，是不是真的有你的文件存在，我这里一直都没有问题，我还是认为你的路进可能有问题
1和2我这样写都没有看过，3不用理了，你没有用到hProcess变量而已，如果你有

if(hProcess>0)
TerminateProcess(hserveProcess,0);

这样关闭你打开的exe文件的话就不会出现了，可以在onclose中写
