能用Controls.Add动态生成控件数组吗?

fishyx 2003-11-18 04:22:00
我想要生成一个控件数组,同时,我希望控件的名称要由变量获取(用load就无法做到),例如根据要求要在不同的情况下生成com1(i)控件或com2(i)控件。
我知道如何用Controls.Add动态生成控件,但不知道是否能生成控件数组。目前我只知道该方法可以动态的设置控件的名称,如果有其他的方法,请给出代码示范。
问题解决,一定给分!

Option Explicit

Dim oControl(8) As Object

Private Sub Form_Load()
Dim i As Integer
Dim aleft As Integer
Dim atop As Integer

aleft = 10
atop = 10


For i = 1 To 5
Set oControl(i) = Controls.Add("VB.CommandButton", "MyButton" & CStr(i))
oControl(i).Left = aleft
oControl(i).Top = atop
oControl(i).Width = 2000
oControl(i).Height = 700
atop = atop + oControl(i).Height + 50
aleft = aleft + oControl(i).Height + 50
oControl(i).Visible = True
Next i

End Sub

上面代码是生成一组的button按钮的。同时递高的。你可以看一下。

你可以用控件的Index属性,没有这个属性的空件当然不行了!
在窗体上放个控件如:image1控件,把index属性设成0,
然后你在代码重要动态生成控件只需要image1(i),然后定义其位置(left,top)
即可动态生成控件。

可以搞定

既然是动态加入控件,干吗还需要用控件数组?
倘若你只是希望通过名称来管理这些控件,那么用一个集合或者集合集即可,例如:
dim myControls as new Dictionary
if not myControls.exists (controlName) then
myControls.add controlName, new Dictionary
end if

myControls(controlName).add controlIndex, Controls.Add("VB.CommandButton", "MyButton" & CStr(i))

此后,即可用 myControls(controlName)(contrlIndex) 来访问你所添加的任何一个控件

需要指出的是:
用Controls.Add动态生成的控件数组不能响应事件。
即你不能这样定义:
Dim withevents oControl(8) As Object
会报错

vf6.0,要考二级没系统的下哈 Microsoft Visual FoxPro 6.0 for Windows 的常见问题 这些是有关 Microsoft Visual FoxPro 最常见的问题。在您求助 Microsoft 产品支持服务之前,请先查阅这张列表。 若想打印这些附注,请从“文件”菜单中选择“打印”命令。此文档分为以下四部分: --------------------------------------------------------------------- 部分 1. 技术支持与市场 部分 2. Visual FoxPro 6.0 新增功能 部分 3. 从其他版本的 FoxPro 和 Visual FoxPro 中移植 部分 4. Visual FoxPro 常见问题 --------------------------------------------------------------------- 部分 1. 技术支持与市场 问题 1-1: 从何处可以获得产品的更新版本? 答案: 在 Visual FoxPro 的 Web 站点上即可获得产品的更新信息,其中包括有关 Service Pack 和更新的示例、向导及其他代码的信息,该站点的网址为: www.microsoft.com/vfoxpro 请定期查看该网站,以便下载产品的最新版本。 问题 1-2: 从何处可以得到有关 Visual FoxPro 的详细资料? 答案: 通过 Microsoft Visual FoxPro Web 站点是随时获得各种最新产品发布信息的最佳途径。在此站点上不仅有新的产品公告,而且还提供了产品的更新信息、技术文章、白皮书、专业开发人员设计的优秀示例、会议公告、以及与其他许多 FoxPro web 站点的各种链接。 问题 1-3: 如何获得技术支持,以及如何报告软件错误? 答案: Microsoft Visual FoxPro Web 站点已经链接到了多种联机支持选项,其中包括覆盖面广阔的有关所有产品 Microsoft Knowledge Base(Microsoft 知识库)。您还可以阅读一份有关常见问题的清单。除联机支持之外,还可以直接通过电话获得技术支持。“帮助”菜单中的选项可列出技术支持的电话号码。这些电话号码也可用于报告产品中的错误。 问题 1-4. 什么是 Knowledge Base?如何使用它? 答案: Knowledge Base 是内容广泛的论文集,覆盖了如何使用产品的各种特性、已知的软件错误及其解决方案或回避的方法、以及其他有助于使用各种 Microsoft 产品的有用信息。通过以下站点可访问整个 Knowledge Base: support.microsoft.com 问题 1-5: 是否会有 Visual FoxPro 6.0a? 答案: Microsoft 公司一向承诺为用户提供高质量的产品。如果确实需要,我们将提供 Visual FoxPro 6.0 的错误修订版。但是,修订版不会使用 6.0a 版的形式。Visual FoxPro 6.0 中任何错误的修正都将包含在 Visual Studio Service Pack 中。同时还会在 Visual FoxPro 的 www.microsoft.com/vfoxpro 或 Visual Studio 的www.microsoft.com/vstudio 的 Web 站点上发布修订公告。 问题 1-6: Microsoft 公司为应用程序的开发提供了一些优秀的解决方案。怎样才能知道应该向客户推荐和使用哪种产品? 答案: 在选择适用某项任务的产品时,需要考虑多方面的因素。Microsoft Visual FoxPro web 站点上有一份优秀的策略背景论文,它比较了 Visual FoxPro、Visual Basic、SQL Server 和 Access 等 Microsoft 产品之间的不同。 问题 1-7: 哪里可以找到 Visual FoxPro 的使用示例? 答案: Visual FoxPro 6.0 产品中带有丰富的示例,其中有一些是针对 6.0 版特有功能的新示例。与 Visual FoxPro 以前的版本不同,这些示例将与所有 Visual Studio 示例安装在一起。您必须运行 MSDN Library 的“自定义”安装来安装这些示例。在 Visual FoxPro 中可使用新的 HOME(2) 函数方便地找到已安装示例的位置。 除了产品中所自带的示例外,Microsoft Visual FoxPro web 站点还将经常提供新的示例。
