I think thats the problem, many ms apps try to solve problem, which is nice, but the problem is they dont give any hint about what they are doing.
However this doesnt happen when the SAME library to connect is used by ordinary application, only when it is used by .net object hosted in IE (oh yah, the connection setting is also included in the library, the caller (ordinary app or .net object hosted in IE) just call the function in library without parameter at all). So there should be some thing different regarding the network handling between ordinary application and IE. Ill try to find it out, meantime is there some one already knows how IE handles this differently?
Tx again in advance
