如何使用变量获取表单的TextBox控件的值？ [英] How do I get the value of a form's TextBox control using a variable?

问题描述

我试图通过使用变量输入对它的引用来从表单的TextBox控件中获取值。我正在输入模块中的代码。这是我尝试过的，但它不起作用。我得到字符串文本，但不是控件的值。
如何将对象的字符串引用转换为对表单上控件文本框的实际引用？

 Dim TextBoxText As String 
  TextBoxText =" frmAddEditAssets.txtProjFed" &安培; YearNumber& "。文本" 
  DepreciationFed = TextBoxText 
 frmAddEditAssets.txtDeprFed.Text =格式（DepreciationFed，" Standard"）
 

但是，如果我硬连接第二行代码，所以没有YearNumber变量，如下所示，它可以工作：

  TextBoxText = frmAddEditAssets.txtProjFed2.Text  

我做错了什么？感谢您的帮助。

您好

嗯，Form控件，TextBox，需要通过其名称来解决。

例如，Form上的默认TextBox将命名为TextBox1，并且可以按以下方式使用：TextBox的属性"Text"是找到文本的位置。

 Dim myVar1 As String ="我的朋友。" 
 TextBox1.Text =" Hello there" 
 Dim myVar2 As String = TextBox1.Text& "，" &安培;你的样本中的myVar1 
 

，确实没有涉及任何TextBox，只是字符串

I am trying to get the value from a form's TextBox control by entering a reference to it using a variable. I am entering the code in a Module. Here is what I have tried, but it isn't working. I get the string text, but not the value of the control. How do I convert the string reference to the control into an actual reference to a control textbox on a form?

Dim TextBoxText As String
TextBoxText = "frmAddEditAssets.txtProjFed" & YearNumber & ".Text"
DepreciationFed = TextBoxText
frmAddEditAssets.txtDeprFed.Text = Format(DepreciationFed, "Standard")

However, if I hardwire the second line of code so there is no YearNumber variable, like below, it works:

TextBoxText = frmAddEditAssets.txtProjFed2.Text

What am I doing wrong? Thank you for help.

Hi

Well, a Form control, a TextBox, needs to be addressed by its name.

For example, a default TextBox on a Form would be named TextBox1, and can be used in the following manner: the Property 'Text' of the TextBox is where the text is found.

    Dim myVar1 As String = "my friend."
    TextBox1.Text = "Hello there"
    Dim myVar2 As String = TextBox1.Text & ", " & myVar1

in your sample, there really isn't any TextBox involved, just strings
