本程序实现vb创建真正的全局dll 步骤： 1.为所要产生的dll编写.def文件 2.编译代理LINK，产生LINK.exe，然后将vb工具下的LINK.exe改名为LINKlnk.exe，将我们自己产生的LINK.exe放过去 3.编译manthlib，产生manthlib.dll 4.可以测试产生的dll可全局调用了。 注意生成dll路径也要指向vb工具目录-Vb realize this procedure to create a true global dll steps: 1. For the resulting dll to the preparation. Def files 2. Compilers Deputy LINK, have LINK.exe, then vb tools LINK.EXE renamed under LINKlnk.exe, our LINK.EXE generated their own place over the past 3. compilers manthlib, have manthlib.dll4. to test the overall situation can be generated by calling the dll.
