Hi,

I would like to know if anyone knows any example (in C++) to read data from keyboard, as the HID examples. My application has no windows.

Thanks,

Seabra.

Hi Martin,

How you defined the method that initializes the device?

Thanks,

Rodrigo.

Hello Martin,

Right. Now, my comprehension improved. But is not lacking in its previous code set the variable m_bStopping flag to FALSE, at start of thread?

What is the exact point where this should be done?

Thanks,

Rodrigo.

Hi Martin,

I believe that you didn't see my previous message ... Could you give me the definition of the method IsStopping?

Thank you very much...

Rodrigo.

Hi Martin Soch,

Where is the definition of the method IsStopping()? I would like to know what this method means in your code...

Thank you very much for your attention help me...

Rodrigo.

Hi sochm, I'm trying to do exactly the same as you did in your application, including the asynchronous handling of device, but I am working with only one. I have tried several combinations of parameters of methods ReadFile, WaitForSingleObject and GetOverlappedResult, however, no sucess. During the ...

Sorry, a line is hidden. case ERROR_IO_PENDING: BOOL bPending = TRUE; while(bPending) { if (!GetOverlappedResult(pDev -> handle, &overlapped, &ntransferred, FALSE)) { switch (dwError = GetLastError()) { case ERROR_IO_PENDING: cout << "ainda pendente..." << endl; break; case ERROR_I...

Right. The error is that driver of SpaceNavigator was off. After connecting the driver, the current error is: "ERROR_IO_INCOMPLETE" if (FALSE == ReadFile(pDev -> handle, pDev -> buf, pDev -> capabilities.InputReportByteLength, NULL, &overlapped)) { switch (dwError = GetLastError()) { c...

I understand. However, I tried to use:
The function GetLastError returns the value "6"... What I do?

Thanks.

Hi, In HIDTest example, the application is in a loop that gets the coordinates of translation and rotation of Spacenavigator. In my application, I tried to adapt the same code and strategy to read the coordinates of the device, however, as my application already makes use of a main loop that updates...

Hi ngomes, I know how to operate the event handlers in general, however, for most it has tried, I could not do the correct use of methods hr = __hook (...) mentioned in the documentation of 3DxInput API. Me seems that I need them to capture the events generated by the SpaceNavigator. Considering the...

How I do to receive events of device???

Hi, I have a doubt. In my application, I connected the SpaceNavigator, but I don't understand how to link the event handlers to connexion device. Someone could help me? #include "spacenavigator.h" #define UnknownDevice 0 using namespace std; CComPtr<IUnknown> _3DxDevice; CComPtr<ISensor> g...

Ok alexus.

If you have the code in C#, maybe I can convert it to C++
