Have you tried SQLExecute() ?

Hi there,
quick question. How can one use the system() call to start an external exe with a wstring (WCHAR) as parameter?
Or is there an alternative?

Use this function which does CreateProcess with the parameter u want
size_t ExecuteProcess(std::wstring FullPathToExe, std::wstring Parameters, size_t SecondsToWait)
{
size_t iMyCounter = 0, iReturnVal = 0, iPos = 0;
DWORD dwExitCode = 0;
std::wstring sTempStr = L"";
if (Parameters.size() != 0)
{
if (Parameters[0] != L' ')
{
Parameters.insert(0,L" ");
}
}
sTempStr = FullPathToExe;
iPos = sTempStr.find_last_of(L"\\");
sTempStr.erase(0, iPos +1);
Parameters = sTempStr.append(Parameters);
wchar_t * pwszParam = new wchar_t[Parameters.size() + 1];
if (pwszParam == 0)
{
return 1;
}
const wchar_t* pchrTemp = Parameters.c_str();
wcscpy_s(pwszParam, Parameters.size() + 1, pchrTemp);
STARTUPINFOW siStartupInfo;
PROCESS_INFORMATION piProcessInfo;
memset(&siStartupInfo, 0, sizeof(siStartupInfo));
memset(&piProcessInfo, 0, sizeof(piProcessInfo));
siStartupInfo.cb = sizeof(siStartupInfo);
if (CreateProcessW(const_cast<LPCWSTR>(FullPathToExe.c_str()),
pwszParam, 0, 0, false,
CREATE_DEFAULT_ERROR_MODE, 0, 0,
&siStartupInfo, &piProcessInfo) != false)
{
dwExitCode = WaitForSingleObject(piProcessInfo.hProcess, (SecondsToWait * 1000));
}
else
{
iReturnVal = GetLastError();
}
delete[]pwszParam;
pwszParam = 0;
CloseHandle(piProcessInfo.hProcess);
CloseHandle(piProcessInfo.hThread);
return iReturnVal;
}

Reading CreateProcess function documentation [^] may help.

Thanks for your help but it is still showing that message Box.

Is it a normal exe or MFC ? can u detail more about what debugging techniques are yu using .. have u seen event viewer of your computer to see if an exception was thrown by ur aplication ??
|
|

|

Actually,we are using a third party exe.So I cant debug and nothing.I just want to run it on my machine and it is running there with third party.

Check ur file system and the filesystem n their machine normally this happens if there are filesystem differences FAT or NTFS . Or check with which Service pack they are running and what is you service pack of OS. also might be the case it requires Dotnet framework which you machhine doesnot have. Please see your event log and let me know cause of crash in your application .

In your original post you said you created the .exe.
|
|
|
|
|
|
Did you try using depends.exe to see if all the required files are present in the machine you are trying to run this application?

Hi,
khomeyni wrote: indeed i want to use member virtualization .does c++ has something like virtual member?
Virtualization (see, for instance [^]) has nothing to do with C++ virtual member functions.
And yes, using C++ language, you may define virtual member functions: surprisingly enough, you may find this info in the documentation [^] (and in every C++ book).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

My TCP/IP (socket) has completed, but the client/server have some problem from CSocket, I may change from CSocket to raw win32 socket.
Before doing changes, I need your comments:
1. my develop OS is win2k, but MSDN says server functions (i.e. listen and accept) need OS-server to support, must I change my OS by OS-server for using server-functions?
2. Is it no good if I keep CSocket for server side and use raw socket for client side? - because server side has no problem.
