VB6选项卡不显示在窗体上

Question

我最近下载了VB6来打开一个.VBP文件，我正在转换为VB2010。我的目标是在VB6上运行程序，这样我就可以逐行遍历代码，以便调试我在VB2010中从头开始编写的程序。

该程序运行虚拟机，具有如下所示的星形形式：

但是，当我在VB6上查看启动表单时，我看到了：

如您所见，缺少标签页。当我运行代码时，调试器在涉及标签页的第一行中断（FrontWeights等是几个标签页的所有名称 （GRIDS的名称，而不是标签页） < / strong>，调试器中断“FrontWeights.ColWidth（1）= 4280 + 1000”）：

Private Sub Form_Load()
  Screen.MousePointer = 11

  Width = 10680
  Height = 6816
  FrontWeights.ColWidth(1) = 4280 + 1000

有关如何解决此问题的任何帮助？仅供参考 - 这是一个工作项目，所以我会犹豫是否要共享/上传文件。

编辑2：将VM表单更改为整个屏幕显示的内容（即菜单）

编辑3： 有一个.CLS文件，VB6最初无法加载。我手动添加没有。现在，当我运行时，我的错误显示“编译器错误：外部程序无效”

除了你之外没有人能说出发生了什么，但是 - 只是猜测 - TABCTL32.OCX中包含的对SSTabs的引用已被删除（或者被引用替换为mscomctl.ocx，因为TabStrip ......？）并且项目已保存。

至少，我可以告诉你为什么你没有看到表格上的任何其他控件，而不是第一个标签：

下面你会看到一个带有三个标签的表格，每个标签内有一个控件：

SSTabs的工作方式是将控件移到表单外部的左侧以隐藏它：

      Text1.Left = 480           Text2.Left = -74520           Text3.Left = -74520

使用记事本打开.frm文件，控件应该在那里，但你无法在IDE中看到它。

最后，根据您的项目的重要性，我相信您有两个选择：

• 在.frm SSTabs中手动恢复，然后在IDE中将控件放在另一个容器上
• 通过将左侧坐标移动75000
，在.frm文件中手动更改控件位置

我不清楚你确切安装了哪个VB6版本，为了方便起见，我在下面添加了一个完整的.frm.文件，您可以在其中查看存储的SSTabs结构。添加您需要的标签。

同样的引用应添加到.vbp文件中，位于最顶层，靠近其他文件：
