I want to send the double quote character to my CreateProcess function. How can I do the correct way? I want to send all of this characters: "%h"
CreateProcess(L"C:\\identify -format ",L"\"%h\" trustedsnapshot.png",0,0,TRUE,NORMAL_PRIORITY_CLASS|CREATE_NO_WINDOW,0,0,&sInfo,&pInfo);
Here is the full code:
int ExecuteExternalFile()
{
SECURITY_ATTRIBUTES secattr;
ZeroMemory(&secattr,sizeof(secattr));
secattr.nLength = sizeof(secattr);
secattr.bInheritHandle = TRUE;
HANDLE rPipe, wPipe;
//Create pipes to write and read data
CreatePipe(&rPipe,&wPipe,&secattr,0);
STARTUPINFO sInfo;
ZeroMemory(&sInfo,sizeof(sInfo));
PROCESS_INFORMATION pInfo;
ZeroMemory(&pInfo,sizeof(pInfo));
sInfo.cb=sizeof(sInfo);
sInfo.dwFlags=STARTF_USESTDHANDLES;
sInfo.hStdInput=NULL;
sInfo.hStdOutput=wPipe;
sInfo.hStdError=wPipe;
CreateProcess(L"C:\\identify",L" -format \"%h\" trustedsnapshot.png",0,0,TRUE,NORMAL_PRIORITY_CLASS|CREATE_NO_WINDOW,0,0,&sInfo,&pInfo);
CloseHandle(wPipe);
char buf[100];
DWORD reDword;
CString m_csOutput,csTemp;
BOOL res;
do
{
res=::ReadFile(rPipe,buf,100,&reDword,0);
csTemp=buf;
m_csOutput+=csTemp.Left(reDword);
}while(res);
//return m_csOutput;
float fvar;
//fvar = atof((const char *)(LPCTSTR)(m_csOutput)); ori
//fvar=atof((LPCTSTR)m_csOutput);
fvar = _tstof(m_csOutput);
const size_t len = 256;
wchar_t buffer[len] = {};
_snwprintf(buffer, len - 1, L"%d", fvar);
MessageBox(NULL, buffer, L"test print createprocess value", MB_OK);
return fvar;
}
I need this function to return the integer value from the CreateProcess.
