I'm trying to read from an USB HID device, I know how to do it in C# using DLLImport hid.dll, but I want to do it from C++, this way I don't have to declare all the structures, etc, and just include the headers files.
So I downloaded the WDK and then when including the headers files and linking the libraries I'm getting a lot of errors:
#include <windows.h>
extern "C" {
#include <hidsdi.h>
}
int main(){
}
Errors (6 out of 163):
Error 1 error C2065: 'PASSIVE_LEVEL' : undeclared identifier c:\winddk\7600.16385.1\inc\api\hidpi.h 302 driver
Error 2 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int c:\winddk\7600.16385.1\inc\api\hidpi.h 303 driver
Error 3 error C2146: syntax error : missing ';' before identifier 'NTSTATUS' c:\winddk\7600.16385.1\inc\api\hidpi.h 303 driver
Error 4 error C2143: syntax error : missing ';' before '__stdcall' c:\winddk\7600.16385.1\inc\api\hidpi.h 303 driver
Error 5 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int c:\winddk\7600.16385.1\inc\api\hidpi.h 303 driver
Error 6 error C2377: 'NTSTATUS' : redefinition; typedef cannot be overloaded with any other symbol c:\winddk\7600.16385.1\inc\api\hidpi.h 303 driver
OK so I read somewhere that I have to upgrade the Windows SDK too, I had the Microsoft Windows SDK v6.0A, I downloaded and installed the windows SDK v7.0. But then looks like I have two SDK now? How I properly do the SDK upgrade in visual studio?
I very much appreciate your help,
Thanks, Carlos
I found a solution, don't know why this is working, but it is!:
In Visual Studio go to:
Tools->Options->Projects->VC++ Directories and then Show directories for: include files.
Add this folders:
C:\WinDDK\7600.16385.1\inc\ddk and C:\WinDDK\7600.16385.1\inc\api
Now here is the trick that solved the problem for me and I don't know why, because seems odd but here it is:
C:\WinDDK\7600.16385.1\inc\ddk -> This directory have to be the first directory in the list!
C:\WinDDK\7600.16385.1\inc\api -> This directory have to be ABOVE "$(WindowsSdkDir)\include" BUT BELOW "$(VCInstallDir)include"
Example:
C:\WinDDK\7600.16385.1\inc\ddk
$(VCInstallDir)include
$(VCInstallDir)atlmfc\include
C:\WinDDK\7600.16385.1\inc\api
$(WindowsSdkDir)\include
$(FrameworkSDKDir)include
