解决不了了，郁闷

你的InitInstance跟MyRegisterClass 在哪实现啊？
我是没看到……………………

[CrazyAzreal]

如果是IniInstance和MyRegisterClass没实现的话，不是出这种错误提示的。。。我一般在写dll后，调用这个dll，把头文件引入，然后使用dll的函数，才出现这种错误，一般是忘了在dll里导出函数。
要么另一种情况，也是出现这种错误，就是你的类声明里定义了函数原型，而却没有这个函数的实现，就会出错，印象中是这样的

哦，楼上大侠，这个两个不是API函数吗？直接调用不可以吗，还要自己写实现部分吗？本人是菜鸟，望指教。我以为这两个函数和LoadString()一样，直接可以用的呢，望给确认。还有，如果是API，那么相应的头文件是哪个啊，怎么在MSDN里查呢？谢谢

大侠们，帮帮偶啊，偶要郁闷死了

[孤必有邻]

这两个函数好象没有实现(函数体)呀,自己写个简单的实现,再编译
