Methods used by the DLL call
Public class ImportDLL

HLib=LoadLibrary (DLLPath);
Thinking id card read DLL have dynamic library RdCard. DLL relies on sdtapi. DLL WltRS. Two DLLS,
Now with this method call without dependence on other DLLS are no problem, but call RdCard. DLL returns 0, call you don't succeed
Find a lot of way doesn't work, also tried to use LoadLibraryEx effect is
Request to people! thank you

Send the wrong section, the code is the c # oh, the DLL directly to follow LoadLibrary to write good,
Also need to be aware that DLL is 32 and 64 - bit version, if the original poster is a 64 - bit system, compile time to choose the 32-bit version of the X86 mode,

Problem again and again, updated, and finally found the client calls the DLL devices to read data, is not so easy,
New problems come out again: javascript + activeX how call the DLL, because there is no ocx,
Only provide DLL
Wait for... .
