Not able to create a new child process using ZwCreateProcess!

[kiddo]

I am trying to create a new process from current running process,am doing this with the zwcreateProcess function.(just for testing purpose).check the code below

 HANDLE fileHandle;
    OBJECT_ATTRIBUTES ObjectAttributes;
    UNICODE_STRING InputString;
    InputString.Buffer = L"C:\\users\\Tommy\\MyEXE.exe";
    InputString.Length = wcslen(L"C:\\users\\Tommy\\MyEXE.exe")*2;
    InputString.MaximumLength = InputString.Length +2;
    ObjectAttributes.Length = sizeof(OBJECT_ATTRIBUTES);
    ObjectAttirbutes.ObjectName = &InputString;
    NTSTATUS status = ZwCreateProcess(&fileHandle,PROCESS_CREATRE_PROCESS,&ObjectAttributes,GetCurrentProcess(),true                ,NULL,NULL,NULL);

status - Invalid Parameter

Any suggestions/help is appreciated.

Your DesiredAccess parameter is wrong. http://msdn.microsoft.com/en-us/library/ms684880%28v=VS.85%29.aspx

And maybe you didnt initializie the ObjectAttributes correctly.

i am using this:

#define InitializeObjectAttributes(p,n,a,r,s) \
{ \
	(p)->Length = sizeof(OBJECT_ATTRIBUTES); \
	(p)->ObjectName = n; \
	(p)->Attributes = a; \
	(p)->RootDirectory = r; \
	(p)->SecurityDescriptor = s; \
	(p)->SecurityQualityOfService = NULL; \
}OBJECT_ATTRIBUTES ObjectAttributes;
InitializeObjectAttributes(&ObjectAttributes, 0, 0, 0, 0);
