DLL函数未被执行 [英] DLL functions not being executed

问题描述

我为我正在处理的相机项目编写了一个DLL。 DLL是相机和更大的软件应用程序之间的接口。当它包含在测试Windows项目中时，DLL工作得很好，但是当我尝试将它合并到主
软件应用程序中时，它失败了。

I wrote a DLL for the camera project that I am working on. The DLL is an interface between the camera and a larger software application. The DLL works perfectly when it is included in a test windows project, but when I try to incorporate it into the main software application it fails.

我正在尝试的功能要执行的是初始化摄像机并打开一些设置，但这会失败。

The function that I am trying to execute is to initialise the camera and turn on a few settings, but this fails.

我确保DLL输出路径是正确的，但我想知道如何测试是什么出错了？ 我还应该注意什么？ 我已经看过关于检查在运行时加载的模块的帖子，但是我的DLL似乎永远不会加载
即使正确初始化相机也是如此。

I have ensured that the DLL output path is correct, but I wondered how I can test what is going wrong?  What else should I look out for?  I have seen posts about checking the modules that are loaded during runtime, but my DLL never seems to get loaded even when the camera is initialised properly.

Hi WithSPDev,

感谢您在此处发帖。

>> DLL工作正常它包含在测试Windows项目中，但是当我尝试将其合并到主软件应用程序中时，它会失败。

请提供有关如何调用这些函数的更多信息DLL。什么是DLL的类型和主要的软件应用程序？

Please provide more information about how you call these functions in DLL. And what's the type of the DLL and your main software application ?

可执行文件以两种方式之一链接到（或加载）DLL：

An executable file links to (or loads) a DLL in one of two ways:

隐式链接

明确链接
