将标题转换为文本框中的字符串时出现运行时错误 [英] Runtime error while converting caption to string in textbox

问题描述

  Imports  AxChemDrawControl12 
  Public  类 Form1 
 
  Dim 标题 As  字符串 
 公共  Sub  Button1_Click（发件人作为 对象，e 作为 EventArgs）句柄 Button1.Click 
  TextBox1.Text = AxChemDrawCtl1.selection.Objects.Captions  
 结束  Sub  
 结束 类 

解决方案

在我看来，标题是一个数组。也许试试：

 TextBox1.Text = AxChemDrawCtl1.selection.Objects.Captions（ 0 ）

Imports AxChemDrawControl12
Public Class Form1

    Dim caption As String
    Public Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        TextBox1.Text = AxChemDrawCtl1.selection.Objects.Captions
    End Sub
End Class

解决方案

it seems to me that captions is an array. maybe try:

TextBox1.Text = AxChemDrawCtl1.selection.Objects.Captions(0)
