Hi,
I am calling a DLL(from third party) function that is communicate will pc comm port. The DLL function is using sin/sout which written in C language.
When i call this functions(open port, send/get data and close port) continuely(within timer control), it had cause many prblem to my app. I found that it will cause my system clock become late after i run this over night, and my app will not stable, always perform illegal operation. I also found that when perform the communication work with comm port, when my form minimize,it will cause illegal operation.
Actually i did it in Visual basic, and i wish to know is it if i do it in VFP also will get this problem ?
