界面分成多个DLL小组并行开发

[大雄猫]

我试了一下,使用mfc.总是会有错误提示.然后我把全部的文件放在主程序里面,就什么事情都没有了.一分成DLL就有错．我也照着微软的提示做了．

大家谁有过这方面的经验？

[大雄猫]

谢谢,我试试

怎么分？我们有自己的底层界面库，也没出什么问题啊

估计什么地方搞错了吧！我也是这么做的，好像可以

你做的dll是扩展dll吗？标准dll不能导出类

[大雄猫]

我在DLL里面做了一个对话框,想把它做为子窗口,放在主程序的父窗口里面.在dll的接口处传入父窗口的窗口句柄,结果子窗口的创建过程出错,好象是判断父窗口的句柄是无效的.然后在退出时也是出错.

// Note!
//
// If this DLL is dynamically linked against the MFC
// DLLs, any functions exported from this DLL which
// call into MFC must have the AFX_MANAGE_STATE macro
// added at the very beginning of the function.
//
// For example:
//
// extern "C" BOOL PASCAL EXPORT ExportedFunction()
// {
// AFX_MANAGE_STATE(AfxGetStaticModuleState());
// // normal function body here
// }
//
// It is very important that this macro appear in each
// function, prior to any calls into MFC. This means that
// it must appear as the first statement within the
// function, even before any object variable declarations
// as their constructors may generate calls into the MFC
// DLL.
//
// Please see MFC Technical Notes 33 and 58 for additional
// details.
