如何使用Python读写Visio Shape数据

Question

在检查Visio形状的单元格时，以下代码不会返回预期值：

costVal= shpObj1.CellsU("Prop.Cost")
print (costVal) 

[注意-这是一个问题的摘要，在我回答时被删除了，但这是一个有用的问题，因此我认为我会提出并回答它。]

要在Visio中获得ShapeSheet单元格的值，您必须询问该单元格的Result properties之一。

import os
import win32com.client

from win32com.client import constants

# this sample assumes that Visio is running, that the ActiveWindow
# is a Drawing window and that the Selection.PrimaryItem
# is a 'Decision' shape from the 'Basic Flowchart Shapes' stencil

# get the running app
appVisio = win32com.client.GetActiveObject("Visio.Application")

# selection gets you the 1 or more selected shapes and
# the PrimaryItem returns the main / primary item in that selection
# or null if the selection is empty
targetShp = appVisio.ActiveWindow.Selection.PrimaryItem

# set the cell
targetShp.CellsU("Prop.Cost").FormulaU = "=2.50"

# read the cell using its 'internal units' result property
print(targetShp.CellsU("Prop.Cost").ResultIU)
