请教高手：VC中加载MinGW生成的Dll总是失败？

[fuyulin888fly]

HINSTANCE hdll;
hdll=::LoadLibrary("C:\\windows\\daemon.dll");
hdll=::LoadLibrary("libmsn.dll");
第一个调用是windows下自带的dll，还回值hdll非NULL(即正常)；
第二个调用是gaim下的dll，还回值hdll始终是NULL(异常)，不管用绝对还是相对路径，也试过AfxLoadLibrary也是同样结果。下面是libmsn.dll前面的一点信息：

[珍惜生命远离CPP]

先GetLastError看看什么错误

libmsn.dll这个dll是否依赖其他dll?

[fuyulin888fly]

尝试了LoadLibraryEx好像就可以了,为什么?

[DentistryDoctor]

你看一下错误代码是多少？

[fuyulin888fly]

LoadLibrary 的错误代码是126.像下面这样就dll加载没有问题了,但是调用dll里的函数出现Unhandled exception: 0xC0000005 : Access violation:
代码如下:
typedef gboolean (*PFun)(GaimPlugin *plugin);

HMODULE hdll;
hdll=::LoadLibraryEx("libmsn.dll", NULL, 1);
PFun gaim_init_plugin;
gaim_init_plugin = (PFun)GetProcAddress(hdll,"gaim_init_plugin");
GaimPlugin gmPluginGaim;

gaim_init_plugin(&gmPluginGaim); //在此处产生异常
