[solved] run another program in the background?

[FlyingBear]

is it possible to call another program in the background?

I'n doing a project that uses .net to control a camera. the camera is nikon, which has a sdk. unfortunately, the sdk is an unmanaged dll, from the research I did, people complained that it is difficult to use it in .net. actually, no1 has example. but the sdk has sample in vc++. so, I'm thinking maybe can build the control program by vc++, then use vb.net or c# to it and run it in the background. so, I do not have to mess the dll to .net.

is this a good choice? or, not really? how to do it? if I use a console program, how to avoid popping up the cmd window?

thanks
