关于jawin的一个问题，用过的人请进，在线等。。。。

[conning333]

I can run successfully of the demo programe:

FuncPtr msgBox = new FuncPtr("USER32.DLL", "MessageBoxW");

msgBox.invoke(0, "hello", "jawin", 0, ReturnFlags.FAIL_ON_FALSE);

but if I change the “USER32.DLL” by another dll,I receive the error message :

org.jawin.COMException: 8007007f: ???????¨????ò??

I have place the dll to “c:\window\system32” and have use the “regsrv32” command to register it.

我也用过,的确换一个其他dll就会出错
他的demo中提供2种调用USER32.DLL的方法
给我感觉jawin只能调用固定的几个dll
up一下,请高手指点~

dll文件有两种：1。封装函数；2。封装对象。
如USER32.dll即是封装了函数。
你出的那个错误应该是未找到你指定的函数名。
你可以下个dll查看器(ViewDll)，查看一下你的dll文件有哪些函数接口。如果只有四个函数(如DllGetClassObject)那么它就是封装了对象。

推荐你使用NJawin(New Jawin)是jawin的新版本。
它包括jcomgen.exe可以生成所封装对象的.java类文件。
