阅读注册表 [英] Reading the registry
本文介绍了阅读注册表的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
好的，我真的需要一些帮助！我不是最好的C程序员，但通常可以找到自己的方式.但是这个让我难过.我工作的公司使用开源程序从我们的会计软件打印PDF文件已有大约6年的历史了.该程序最初是用V $ C 6.0编写的.现在，根据Abode的终极知识，他们决定更改发布Adobe Reader 10.x时在程序中使用的功能的名称. (我了解他们的原因，但是...)我找到并下载了该程序，然后将该程序导入了VS 2005 C项目.我能够对其进行修改以与Adobe 10.x一起使用，但不适用于Adobe 9.x或更低版本.我进行了一些研究，发现Adobe在Windows注册表中添加了应用程序名称，因此我要做的就是读取注册表项并完成操作.现在，在处理了2天之后，我为无法将其编译为程序感到沮丧.我不知道自己缺少什么，将不胜感激！在下面的代码中，您可以搜索"adobeversion"，并且可以看到我正在尝试执行的操作.我正在尝试使用RegistryKey类，但是出现编译错误.我知道这很长，但是我觉得最好看整个程序.
再次感谢！！
OK I really need some help here! I am not the best C programmer out there but I can usually find my way through. But this one has me stumped. The company I work for has been using an open source program to print PDF file from our accounting software for about 6 years. The program was originally written in V$C 6.0. Now in Abode''s infinate wisdome they decided to change the name of the function that was used in the program when Adobe Reader 10.x was released. (I understand their reason, but...) I found and downloaded the program and I imported the program into a VS 2005 C project. I was able to modify it to work with Adobe 10.x but it would not work for Adobe 9.x or below. I did some research and found that Adobe was adding the application name in the Windows Registry so all I had to do was read the registry key and be done with it. Now after working on this for 2 days, I am frustrated that I can not get this to program to compile. I do not know what I am missing and any help would be MUCH appreciated! In the code below you can search on "adobeversion" and you can see what I am trying to do. I am trying to use the RegistryKey class but I get compile errors. I know this is long but I felt it would be better to see the entire program.
Thanks again in advance!!

</filename>Just trying to read between the lines here, so please bear with me...
I note your reference to C and your programming abilities, I then notice a word that gets my attention - ''class''. Hmm, is this an attempt to use a class from a C program I wonder?
I checked MSDN here[^], finding that the RegistryKey class appears to be for .NET
Also, the reference to "Registry.ClassesRoot" made me suspicious that code was being mixed from both C and .NET C++.
Given that you appear to be using plain win32 api functions, I''d suggest a look at the Registry functions for win32 at msdn. They''re over here[^].
