执行Dll期间进度条不显示 [英] Progress bar increament during execution of Dll

问题描述

大家好，
使用dll进行大型项目实施的出色技术，但很难实施，但存在很多里程碑式的问题.

新的早晨，我的新DLL问题！!!!
__________________________________________________________________________________

当我通过编译实现dll时，出现了一些代码.
就像我根据用户选择创建一个.cpp和.h文件，然后使用GNUIM g ++和c ++编译器进行编译. 一切都很棒！
但是当我考虑到Progressbar时出现了问题.
那就是随着编译进度，我会根据编译文件增加进度栏.
但是编译会保留maitain dll，因此我如何根据DLL项目中的文件编译来增加主调用项目的进度栏.

Hello All,
Greate techonology using dll for big project implementation but so hard to implement with lots of milestone problem.

New morning my new DLL problem!!!!
__________________________________________________________________________________

As i implemented dll fro compilation some code.
Like i create a .cpp and .h file as per user selection and compile i with GNUIM g++ and c++ compiler.
Things work greate!!!
but problem arised when i consern Progressbar.
That is As compilation progress i increase progressbar as per compilation files.
but compilation has saparate maitain dll so how i increase progress bar of main calling project as per compilation of files in DLL project.

这是控制反转的问题，请参见http://en.wikipedia.org/wiki/Inversion_of_control [ ^ ].

就您而言，问题是:您的DLL提供了一些要在主机应用程序中使用的资源.如果您的应用程序是唯一的因果关系来源，那么您将无法解决问题，因为只有您的主机应用程序会触发呼叫.您需要倒转情况:您的DLL需要调用某些东西来触发事件，从而在主机的UI中呈现一个步骤.解决方案是回调方法. DLL中的类应接受回调并调用此回调(让我们说"OnProgressStep")；主机应用程序应提供回调代码.

This is a problem of inversion of control, see http://en.wikipedia.org/wiki/Inversion_of_control[^].

In your case the problem is: you DLL provides some resource to be used in a host application. If your application is the only source of causality, you cannot solve your problem, because only your host application triggers a call. You need inverted situation: your DLL needs to call something which triggers the event presenting a step in the host''s UI. The solution is a callback method. A class in a DLL should accept callback and call this callback (let''s say "OnProgressStep"); a host application should provide a callback code.
