如何使用 Python 读取和写入 Visio 形状数据

Question

检查 Visio 形状中的单元格时，以下代码不会返回预期值：costVal= shpObj1.CellsU("Prop.Cost") print (costVal)[注意 - 这是一个在我回答时被删除的问题的摘要，但这是一个有用的问题，所以我想我会问并回答它。]

Answer 1

要在 Visio 中获取 ShapeSheet 单元格的值，您必须对单元格的结果属性之一进行交互。

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)
