推荐答案

我从这里以FYI的身份获得了此信息:
http://www.codeproject.com/KB/vb/VBFileAssociation.aspx [ ^ ]

因此，访问注册表并打开HKEY_CLASSES_ROOT部分.

然后，找到.pdf
的密钥
默认值列出了它的文件类型.

然后，在同一部分中打开该类型文件的密钥.

此键的子键为shell，子键为open，子键为command.

此命令列出了用于打开文件的默认程序(在我的情况下，它列出了"C:\Program Files\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe" "%1").

而且您没有指定VB的版本(VB6或.Net)，而是在此处介绍了使用这两种方式访问​​注册表的文章:

I got this info from here as an FYI:
http://www.codeproject.com/KB/vb/VBFileAssociation.aspx[^]

So, access the registry and open up the HKEY_CLASSES_ROOT section.

Then, find the key for .pdf

The default value lists the type of file that it is.

Then, open up the key for that type of file in the same section.

This key will have a subkey of shell which has a subkey of open which has a subkey of command.

This command lists the default program used to open the file (in my case, it lists "C:\Program Files\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe" "%1").

And you didn''t specify which version of VB (VB6 or .Net) but here''s an article that explains accessing the registry using both: Accessing the Registry with VB6 and VB.NET[^]
