Excel 的 Form Controls & 之间的差异ActiveX 控件 [英] Differences between Excel's Form Controls & ActiveX Controls
问题描述
为什么 Excel 中有2 种类型的控件?(2 个按钮、2 个组合框、2 个复选框等...)
表单控件和ActiveX控件之间有什么区别?我应该使用哪个?
我在网上找到的一些代码示例可以与我的控件一起使用,但其他代码示例则不能.怎么来的?
我如何处理每种类型,如何区分?
围绕 Excel 可用的两种控件类型存在[永恒的]混淆 - 对比术语em> 被不同的在线资源使用.
这只是对 Form Controls 和 ActiveX Controls 之间差异的一般概述(基于帮助我最终弄清楚的旧笔记找出差异!)访问包含的链接以获取有关每个控件的更多详细信息,包括代码和示例项目.☺
(改编自我的原始帖子.)
例如,让我们比较两种类型的组合框.在某些编程语言中,类似的控件被称为下拉菜单" 或下拉列表".在 Excel 中,我们有一个 "Form Control Combo Box" 和一个 "ActiveX Control Combo Box":

ActiveX 控件事件
ActiveX 控件有一个更广泛的事件列表,它们可以设置为响应这些事件.
要将事件分配给 ActiveX 控件,请右键单击该控件并选择 View Code
.在 VBE 中,您可以粘贴代码,或从 VBE 窗口右上角的下拉列表中选择特定事件.

控制用户表单上的事件处理:
事件也可用于用户窗体的控件中.由于只有 ActiveX 控件可以放置在用户窗体中,因此您将需要进行更多编码 + 更多功能"的权衡.
ActiveX 控件添加到用户表单的方式与添加到工作表的方式相同.请记住,分配给用户表单本身(即背景)的任何事件都将在控件覆盖的任何区域中被阻止",因此您可能需要将相同的事件分配给控件以及用户表单.
例如,为了让这个用户表单响应MouseMove
表单上的任何地方,同样事件代码应用于用户表单、文本框、选项按钮和框架:

Why are there 2 types of controls available in Excel? (2 buttons, 2 combo boxes, 2 check box, etc...)
What's the difference between Forms Controls and ActiveX Controls? Which one should I use?
Some code samples I find online work with my controls, but others do not. How come?
How do I work with each type, and how can I tell the difference?
There is [eternal] confusion surrounding the two types of controls available to Excel — exacerbated by the contrasting terminology used by different online sources.
This is only a general overview of the differences between Form Controls and ActiveX Controls (based on my old notes that helped me finally figure out the differences!) Visit the included links for more detailed information about each control including code and sample projects. ☺
(Adapted from my original post here — now closed)
Overview:
There are two types of controls: Form controls and ActiveX controls:
Both types of controls can be used on worksheets but only ActiveX controls can be used on userforms.
Form controls are part of the Shapes collection (just like Drawing Objects), and thus are referred to like:
ActiveX controls are basically part of the worksheet and are therefore referred to like:
Both types of controls can be created, modified and deleted from either the worksheet, or programmatically with VBA, however, the 2 types of controls have slightly varying syntax when using VBA to refer to them.
Some sites discuss also discuss a Data Form. This is nothing more than a userform made specifically for data entry/manipulation of data, so it would've made more sense to call them (the more familiar sounding) "Data Entry Userform".
Office documentation also occasionally refers to a worksheet as a form. While this is technically correct, don't let this confuse you. Think of the word "form" as being used in a general sense:
Two Types of Controls
Form Controls
ActiveX Controls
The two look, behave, and are controlled similarly, but not identically. (List here.)
For example, let's compare the two types of Combo Boxes. In some programming languages, comparable controls are referred to as a "drop-down menu" or "drop-down list". In Excel, we have a "Form Control Combo Box", and an "ActiveX Control Combo Box":

☆ "Default name" applies to controls created manually. Controls created programmatically do not have (or require) a default name and therefore should have one assigned immediately upon creation.

Control Availability
This image below shows which common controls are generally available for use in Worksheets and User Forms.
Other factors may affect control availability.

About ActiveX controls and related Security Concerns
An ActiveX control is an extension to the VBA Toolbox. You use ActiveX controls just as you would any of the standard built-in controls, such as the CheckBox control. When you add an ActiveX control to an application, it becomes part of the development and run-time environment and provides new functionality for your application.
An ActiveX control is implemented as an in-process server (typically a small object) that can be used in any OLE container. Note that the full functionality of an ActiveX control is available only when used within an OLE container designed to be aware of ActiveX controls.
This container type, called a control container or control object, can operate an ActiveX control by using the control’s properties and methods, and receives notifications from the ActiveX control in the form of events. The following figure demonstrates this interaction:

Option Buttons (Radio Buttons)
In Excel, the two types of radio buttons are actually called Option Buttons. To further confuse matters:
the default name for the form control is
OptionButton1
.the default name for the ActiveX control is
Option Button 1
.
A good way to distinguish them is by opening the control's Properties list (on the ribbon under the Development tab, or by right-clicking the control and choosing Properties
, or hitting F4), because the ActiveX control has many more options that the simpler form control.
Option buttons and checkboxes can be bound together (so only one option at a time can be selected from the group) by placing them in a shared Group Box.
Select the group box control and then hold Ctrl while selecting each of the other controls that you want to group. Right-click the group box control and choose
Grouping
→Group
.
The first two links below are separate sets of instructions for handling each type of option button.
HANDLING CONTROL EVENTS:
Form control events (Click
event only)
Form control events are only able to respond to one event: the Click
event. (More info here.) Note that this section doesn't apply to userforms since they use only ActiveX controls.
To add a procedure for the Click
event:
Right-click the control and choose
Assign Macro...
In the 'Assign Macro` Dialog:
Select an existing procedure, and click OK, or,
Create a new procedure in the VBE by clicking New..., or,
Record a new macro by clicking Record..., or,
to Remove the assigned event, delete its name from
Macro Name
field and click OK.
(Click image to enlarge.)
To rename, edit or delete existing macros, hit Alt+F8 to open the Macro
interface:
ActiveX control events
ActiveX controls have a more extensive list of events to which they can be set up to respond.
To assign events to ActiveX controls, right-click the control and choose View Code
. In the VBE, you can paste in code, or choose specific events from the drop-down list at the top-right of the VBE window.
(Click image to enlarge.)
Control event handling on a userform:
Events can also be used in controls on userforms. Since only ActiveX controls can be placed a userform, you'll have the "more coding + more functionality" trade-off.
ActiveX controls are added to userforms the same way as they are added to a worksheet. Keep in mind that any events assigned to the userform itself (ie., background) will be "blocked" in any areas covered up by a control, so you may need to assign the same events to the controls as well as the userform.
For example, in order to make this userform respond to MouseMove
anywhere on the form, the same event code was applied to the userform, textboxes, option buttons and the frame:
VBA EXAMPLES
Add/Modify/Delete a form control option button using VBA:
Sub formControl_add()
'create form control
Dim ws As Worksheet: Set ws = ActiveSheet
With ws.Shapes.AddFormControl(xlOptionButton, 25, 25, 100, 100)
.Name = "cOptionButton1" 'name control immediately (so we can find it later)
End With
End Sub
Sub formControl_modify()
'modify form control's properties
Dim ws As Worksheet: Set ws = ActiveSheet
ws.Shapes("cOptionButton1").Select
With Selection 'shapes must be Selected before changing
.Characters.Text = "wxyzabcd"
End With
End Sub
Sub formControl_delete()
'delete form control
Dim ws As Worksheet: Set ws = ActiveSheet
ws.Shapes("cOptionButton1").Delete
End Sub
Add/Modify/Delete an ActiveX command button using VBA:
Sub activexControl_add()
'create ActiveX control
Dim ws As Worksheet: Set ws = ActiveSheet
With ws.OLEObjects.Add("Forms.CommandButton.1")
.Left = 25
.Top = 25
.Width = 75
.Height = 75
.Name = "xCommandButton1" 'name control immediately (so we can find it later)
End With
End Sub
Sub activexControl_modify()
' modify activeX control's properties
Dim ws As Worksheet: Set ws = ActiveSheet
With ws.OLEObjects("xCommandButton1").Object
.Caption = "abcxyz"
.BackColor = vbGreen
End With
End Sub
Sub activexControl_delete()
' delete activeX control
Dim ws As Worksheet: Set ws = ActiveSheet
ws.OLEObjects("xCommandButton1").Delete
End Sub
Add/Remove items from a form control combo box:
Sub ComboBox_addRemoveItems_FormControl()
Dim ws As Worksheet: Set ws = ActiveSheet
'add item to form control combo box
ActiveWorkbook.Sheets("Sheet1").Shapes("Drop Down 1").ControlFormat.AddItem "abcd"
'remove all items from from form control combo bo
ActiveWorkbook.Sheets("Sheet1").Shapes("Drop Down 1").ControlFormat.RemoveAllItems
End Sub
Add/Remove items from an ActiveX combo box:
Sub ComboBox_addRemoveItems_ActiveXControl()
Dim ws As Worksheet: Set ws = ActiveSheet
'add items to ActiveX combo box
ActiveWorkbook.Sheets("Sheet1").ComboBox1.AddItem "abcd"
'remove all items from ActiveX combo box
ActiveWorkbook.Sheets("Sheet1").ComboBox1.Clear
End Sub
