Well I've initialized it as COINIT_MULTITHREADED in CoInitializeEx() but it doesn't work as hoped. I use the same IWbemServices pointer (all initializations done just the first time) to run an ExecNotificationQuery with different WMI queries. However my ExecNotificationQuery fails. The two queries work fine if done individually but I can't seem to be able register for two separate WMI events separately.
If I do the whole initialization again for my 2nd query then I get an error in COM security initialization.
Code Snippet:
HANDLE hres;
hres = CoInitializeEx(0, COINIT_MULTITHREADED);
if (FAILED(hres))
{output something}
hres = CoInitializeSecurity(NULL,1,NULL,NULL, RPC_C_AUTHN_LEVEL_DEFAULT, RPC_C_IMP_LEVEL_IMPERSONATE,NULL, EOAC_NONE,NULL);
hres = CoCreateInstance(
CLSID_WbemLocator,
0,
CLSCTX_INPROC_SERVER,
IID_IWbemLocator, (LPVOID *) &pLoc);
hres = pLoc->ConnectServer(
_bstr_t(L"ROOT\\WMI"), // Object path of WMI namespace
NULL, // User name. NULL = current user
NULL, // User password. NULL = current
0, // Locale. NULL indicates current
NULL, // Security flags.
0, // Authority (e.g. Kerberos)
0, // Context object
&pSvc // pointer to IWbemServices proxy
);
hres = CoSetProxyBlanket(
pSvc, // Indicates the proxy to set
RPC_C_AUTHN_WINNT, // RPC_C_AUTHN_xxx
RPC_C_AUTHZ_NONE, // RPC_C_AUTHZ_xxx
NULL, // Server principal name
RPC_C_AUTHN_LEVEL_CALL, // RPC_C_AUTHN_LEVEL_xxx
RPC_C_IMP_LEVEL_IMPERSONATE, // RPC_C_IMP_LEVEL_xxx
NULL, // client identity
EOAC_NONE // proxy capabilities
);
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecNotificationQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM ..."),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
Then I use pEnumerator->Next within a loop and cleanup.
I run this function twice in separate threads.Ideas?

Hi all,
Is it possible to get client IP from the socket handle to which it is connected.
If possible please let me know.

Hello I have the following code but it isn't working as expected, can't figure out what the problem is.
Basically, I'm executing a process (a .NET process) and passing it command line arguments, it is executed successfully by CreateProcess() but CreateProcess() isn't passing the command line arguments
What am I doing wrong here??
int main(int argc, char* argv[])
{
PROCESS_INFORMATION ProcessInfo;
STARTUPINFO StartupInfo;
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ;
LPTSTR cmdArgs = "name@example.com";
if(CreateProcess("D:\\email\\smtp.exe", cmdArgs,
NULL,NULL,FALSE,0,NULL,
NULL,&StartupInfo,&ProcessInfo))
{
WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
CloseHandle(ProcessInfo.hThread);
CloseHandle(ProcessInfo.hProcess);
printf("Yohoo!");
}
else
{
printf("The process could not be started...");
}
return 0;
}
Hey one more thing, if I pass my cmdArgs like this:
LPTSTR cmdArgs = " manzoor10@gmail.com";
I get the error:
Object reference not set to an instance of an object
then CreateProcess returns TRUE but my target process isn't executed.

good morning
Not sure it will solve your problem but did you notice that lpCommandLine is an in out parameter ?
in MSDN Help i found the following information:
The Unicode version of this function, CreateProcessW, can modify the contents of this string. Therefore, this parameter cannot be a pointer to read-only memory (such as a const variable or a literal string). If this parameter is a constant string, the function may cause an access violation.
Hope this will help.
Regards
Franck

This:
http://bobmoore.mvps.org/Win32/w32tip46.htm[^]
may give you some insight but I'm not sure.
I always use CreateProcess by concatenating the app name and the arguments and set this as the second parameter (first parameter set to NULL) and it has never failed.

I suspect your command-line argument is being interpreted as the executable name. See the CreateProcess[^] documentation:
Console processes written in C can use the argc and argv arguments to parse the command line. Because argv[0] is the module name, C programmers generally repeat the module name as the first token in the command line.
While that's talking about C programs, .NET programs conform to that as well. Add an argument before the e-mail address and you should find it all works.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

You shouldn't be giving him any importance (take a look at some of his recent posts). You could just mark it down instead.

In C run-time libs is there a function that renurns if the given string is a directory or a file name?

Thank you very much, your solution is the right one for C run-times.

Nope. However, you may find these functions [^] useful.

I'm quite sure of the opposite, now. 
I've to admit, I erroneously read 'path' as 'name' (i.e. more caffeine is needed this morning)
