你误解了。 * Access *没有Treeview控件。 Windows有一个

TreeView控件作为Common Dialog库的一部分。要在

中使用此控件，Access意味着添加对外部非本机库的引用，这是使您的Access应用程序依赖于外部库<
的一般做法br />
是要避免的。这是因为版本控制和其他DLL Hell。问题

将破坏你的应用程序。


常见的对话库刚刚经过MS修订后的其中一个

各种版本（通常）彼此不兼容，所以它b / b
是考虑添加引用的最差外部库之一。

幸运的是，几乎全部公共对话库的功能可以通过API调用复制，因此无需添加对它的引用。

不幸的是Treeview不是其中之一。 br />

现在...... MS有可能在最近的

年内稳定了通用对话框库，因此在Access应用程序中使用它会更安全，但是由于使用较新版本的Access，因此不会是
。这将是由于你（和你的用户）

所有使用相对较新的Windows风格。如果你可以指望那么你

可能没问题。我个人在访问应用程序上避免使用任何外部引用

，除非绝对没有其他方式，只有在我的公司应用程序中才能获得

我有一些想法并控制什么是或者没有安装在目标PC上。

对于一般分发的应用程序来说，几乎肯定不会发生麻烦。

几乎肯定会发生。 />

You misunderstand. *Access* doesn''t have a Treeview control. Windows has a
TreeView control as part of the Common Dialog library. To use this control in
Access means adding a reference to an external non-native library and it is the
general practice of making your Access app dependent on external libraries that
is to be avoided. This is because of versioning and other "DLL Hell" problems
that will break your app.

The common dialog library has just been one of those more often revised by MS
with the various versions (usually) not being compatible with one another so it
is one of the worst external libraries to consider adding a reference to.
Fortunately, nearly all of the functionality of the common dialog library can be
replicated with API calls, making it unnecessary to add a reference to it.
Unfortunately the Treeview is not one of these.

Now...it is possible that MS has stabilized the common dialog library in recent
years and therefore it is safer to use in your Access app, but this would not be
due to using a newer version of Access. It would be due to you (and your users)
all using a relatively new flavor of Windows. If you can count on that then you
might be alright. Personally I avoid any external references on my Access apps
unless there is absolutely no other way and only then on my corporate apps where
I have some idea and control over what is or isn''t installed on the target PCs.
For an app that will be generally distributed it is just not worth the hassles
that will almost certainly occur.

Rick，

感谢您的回复。

由于预期Treeview Control仍然存在问题，我昨晚从头开始创建了

a treeview想要的（可能是4小时）工作）

使用一个连续的表格，一个临时表，四个存储过程和

Wingdings字体和100％复制Windows的功能

ActiveX Treeview控件，但也提供图形按钮式对象

的下拉列表。我的版本有两个类似节点的级别，但是

对于可以添加的数量没有限制。此外，它非常快 -

加载约100个级别，10,000条记录。任何对

如何完成感兴趣的人，我会提供更多细节...

Rick,
Thanks for the reply.
In anticipation of the Treeview Control still being an issue, I created
a treeview wannabe from scratch last night (maybe 4 hours work) that
uses one continuous form, one temp table, four stored procedures and
the Wingdings font and 100% replicates the functionality of the Windows
ActiveX Treeview control but also aloows graphical button-like objects
for the dropdowns. My version has two node-like levels though there
would be no limit to how many can be added. Plus it''s extremely fast-
loading about 100 levels with 10,000 records. Anyone interested in how
this was done and I''ll give more details...

Lauren，我想很多人会对完成感兴趣-all-in-Access

替代TreeView。您是否考虑过将其发布到某个地方？

在您进行了更多测试后可以使用它？如果您决定这样做，首先发布它作为测试版版本来限制抱怨。

Lauren, I think many people would be interested in a done-all-in-Access
substitute for the TreeView. Have you considered posting it somewhere and
making it available after you have done a bit more testing? Release it first
as a ''beta'' version to limit the gripes, if you decide to to so.
