完成编辑后，如何以编程方式/自动更改Visio形状文本的文本格式？ [英] How do I programmatically/automatically change the text formatting for the text of a Visio shape after I am done with the editing?

问题描述

这是我想要的东西：
我想使用Visio来记录一个项目。我有一些包含代码示例的Visio文本框。
代码示例中有注释。评论是行评论（行以＃开头，或者是以＃开头的行末尾的位置

我需要的是让Visio更改评论在完成了该形状的编辑（文本正方形）后，自动进行另一种颜色。

从我读到的内容可以通过以下方式实现：

- 使用TheText事件和CALLTHIS（Function-name）

- 功能名称应该阅读形状的文字，并在每行上搜索＃，并将该行的文本转换为灰色，直到行尾。

你能否确认我是否正确的路径？
我是一个全新的Visio和VBA的初学者
为了测试上面我使用了一个应该移动形状的宏编辑完成

Sub Macro（）

 '启用图服务
 Dim DiagramServices As Integer 
 DiagramServices = Active Document.DiagramServicesEnabled 
 ActiveDocument.DiagramServicesEnabled = visServiceVersion140 
 
 ActiveWindow.DeselectAll 
 ActiveWindow.Select Application.ActiveWindow.Page.Shapes.ItemFromID（88），visSelect 
应用程序。 ActiveWindow.Selection.Move 0.5，0＃
 
 
'恢复图服务
 ActiveDocument.DiagramServicesEnabled = DiagramServices 
  

End Sub

而TheText事件单元格则为= CALLTHIS（ThisDocument.Macro）

一旦完成编辑，我预计形状向右移动，但没有发生
我做错了什么？

感谢很多

解决方案

尝试这个子，这不是很好您需要将代码添加到VBA编辑器中的ThisDocument模块中（按Alt + F11打开它）。

p>

实际上，TheText（）事件不会调用fo完成文本编辑后，将会修改文本：在修改文本时（只要按下一个键，格式化或调整文本大小），这将是非常低效的。

我将使用另一个事件，如EvntDoubleClick（）或者用户定义的菜单选项j来调用changeColor子。

  Sub changeColor（oShape As Visio.Shape）
 
错误GoTo Err_changeColor 
 
 Dim iLength As Integer 
 Dim iBeginOffset As Integer， iEndOffset As Integer 
 Dim oShpChar As Visio.Characters 
 
设置oShpChar = oShape.Characters 
 
 iLength = oShpChar.CharCount 
 
'主循环：我们浏览所有选择要素的文本以更改
 Do 
'查找下一个＃字符的位置
 iBeginOffset = InStr（oShpChar.Text，＃）
如果iBeginOffset = 0然后退出Do'＃Not found  - >结束循环
 
'查找下一个LF的位置，以更改颜色，直到行的结尾
 iEndOffset = InStr（iBeginOffset，oShpChar.Text，vbLf）
如果iEndOffset = 0然后iEndOffset = iLength  -  oShpChar.Begin'如果没有找到，更改所有
 
'更新部分更改
 oShpChar.End = oShpChar.Begin + iEndOffset'我们使用前一个开始位置加偏移
 oShpChar.Begin = oShpChar.Begin + iBeginOffset  -  1'Idem。我们想改变＃的颜色，因此（-1）
 
'将所选文本的颜色（从开始到结束之间）更改为绿色（9）
 oShpChar.CharProps （visCharacterColor）= 9 
 
 oShpChar.Begin = oShpChar.Begin + 1'我们不想再找到相同的＃，所以我们撤消上一个（-1）
 oShpChar。 End = iLength'我们要继续搜索直到结束
 
循环While（iEndOffset<> iLength）
 
 Exit_changeColor：
 
如果不是oShpChar没有设置oShpChar =没有
退出Sub 
 
 Err_changeColor：
 
 MsgBox Err.Number& ：& Err.Description，vbExclamation，Error
 Resume Exit_changeColor 
 
 End Sub 
  

Here is what I want to achive: I want to use Visio to document a project. I have some Visio text boxes that contain code examples. The code examples have comments in them. The comments are line comments (either the line begins with # or they are places at the end of the line beginning with #

What I need is to have Visio change the comments to another color automatically after I am done with the editing of that shape (a text square).

From what I read this can be achieved with the following:

-use "TheText" event and CALLTHIS("Function-name")

-the "Function-name" procedure should read the text of the shape and search for "#" on each line and turn the text on that line to let's say "grey" till the end of the line.

Could you please confirm me if I am on the right path with this? I am a totally beginner with Visio and VBA. To test the above I used a Macro that should move the shape as soon as the editing is done

Sub Macro()

'Enable diagram services
Dim DiagramServices As Integer
DiagramServices = ActiveDocument.DiagramServicesEnabled
ActiveDocument.DiagramServicesEnabled = visServiceVersion140

ActiveWindow.DeselectAll
ActiveWindow.Select Application.ActiveWindow.Page.Shapes.ItemFromID(88), visSelect
Application.ActiveWindow.Selection.Move 0.5, 0#


'Restore diagram services
ActiveDocument.DiagramServicesEnabled = DiagramServices

End Sub

And "TheText" event cell had this =CALLTHIS("ThisDocument.Macro")

I expected the shape to move to right as soon as I was done with the editing but it did not happen What am I doing wrong?

thanks a lot P

Try this sub, it's not very well programmed, but it should do the trick.

You need to add the code to the ThisDocument module in the VBA editor (press Alt+F11 to open it).

Actually, the TheText() event won't call the formatting function AFTER you're done with the text editing: It will be called time and again while modify the text (whenever you press a key, format or resize your text box), which would be quite inefficient.

I would use another event, like EvntDoubleClick() instead, or a user defined menu optionj, to call the changeColor sub.

  Sub changeColor(oShape As Visio.Shape)

     On Error GoTo Err_changeColor

     Dim iLength As Integer
     Dim iBeginOffset As Integer, iEndOffset As Integer
     Dim oShpChar As Visio.Characters

     Set oShpChar = oShape.Characters

     iLength = oShpChar.CharCount

     ' Main loop: We go through all the text selecting the adecuate portions to change
     Do
        ' Find the position of next # character
        iBeginOffset = InStr(oShpChar.Text, "#")
        If iBeginOffset = 0 Then Exit Do    ' # Not found -> end the loop

        ' Find the position of next LF to change color only until the end of the line
        iEndOffset = InStr(iBeginOffset, oShpChar.Text, vbLf)
        If iEndOffset = 0 Then iEndOffset = iLength - oShpChar.Begin      ' If not found, change everything

        ' Update the portion to change
        oShpChar.End = oShpChar.Begin + iEndOffset          ' We use the previous beginning position plus the offset
        oShpChar.Begin = oShpChar.Begin + iBeginOffset - 1  ' Idem. We want to change #'s color, too, thus the (-1)

        ' Change color of the selected text (between Begin and End) to green (9)
        oShpChar.CharProps(visCharacterColor) = 9

        oShpChar.Begin = oShpChar.Begin + 1    ' We don't want to find the same # again, so we undo the previous (-1)
        oShpChar.End = iLength                 ' We want to continue searching until the end

     Loop While (iEndOffset <> iLength)

  Exit_changeColor:

     If Not oShpChar Is Nothing Then Set oShpChar = Nothing
     Exit Sub

  Err_changeColor:

     MsgBox Err.Number & ": " & Err.Description, vbExclamation, "Error"
     Resume Exit_changeColor

  End Sub
