If your hWndMain is NULL, your CreateWindow isn't working. A NULL hWnd will cause your SiOpen to fail. Jwick, thank you for the reply! I compared my code with the demo code and found that my code was compiled with Unicode. So I just changed it to default and made it compiled again, then my test cod...

SOrry jwick, I have got a new problem. My test code can not initialize spaceball and connect to it. By debugging the code, i found that my hWndMain and devHdl was always 0x00000000 and didnt change ever. I also debugged demo code 3DxTest32, and found the value of hWndMain changed after execution of ...

oops, i forgot it. now it compiled!
thank you jwick!!!

You are probably getting link errors because you are mangling the names in one place and not in another. I don't know what code you are using. What are some of the names of the functions? To change to C++, change the extension to .cpp, compile, and correct any compiler errors <G>. I change the name...

You can call C from C++ or you can change the code to C++. To call C from C++, enclose the declarations in an extern "C" {...} section. Hey jwick, thank you for the reply. I'v tried the extern "C", i can build the lib. but when i link it to my test.cpp, some link errors showed u...

now i am trying to build a static library for spacemouse so that i can simply use it when my application need to connect spacemouse and get data from it. I have two kind of input data A & B, here A means the data getting from spacemouse. if the system detect A is available, application will use ...

You may have to read up on the HID API. The code is long but fairly easy to understand (IMO). The code reads all the descriptive data from each device into an array. The array is loaded in the order the devices are discovered. The code then attempts to wait on all devices with usage page 1, usage 4...

Yes of course the HIDTest code lists the information for all your devices, but only, I think, prints out the values for the first device in the list. Since your USB bus can constantly have a different arrangement of devices, you need to look at each device descriptor to figure out which one you wan...

If you don't want a windows main loop, you should use the HID API. There are examples posted in the forum. Thank you jwick, for this reply! I have tried HID example, I downloaded the Winddk and complied HIDTest code successfully. But when I run that code, there only showed some figures in the conso...

Hello everyone, I am trying to integrate 3d spacemouse to simulate a joystick. I have the code for joystick mapping, and it was written as a console application.(including a main.app in which there is a main() function). What I need to do is only get the data of spacemouse translation & rotation...
