c＃访问数据库的数据量错误

Question

我有一个Microsoft Access 2010数据库，我使用richtextbox将数据放入一行后有4个单词的文本格式化我得到一个错误，说“该字段太小，无法接受您尝试添加的数据量。请尝试插入或粘贴较少的数据“我确实将表格行设置为255个字符，而我只插入4个单词

Answer 1

Well, a richtextbox contains formatting information, so it will return a much longer text than what you see in the control.

See this code for example:

Option Compare Database
Option Explicit

Private Sub Detail_Click()
    MsgBox Me.RichTextBox0.Value
End Sub

Private Sub Form_Load()
    Me.RichTextBox0.Value = "Only four words really!"
End Sub

This will return:

{\rtf1\ansi\deff0\nouicompat{\fonttbl{\f0\fnil\fcharset0 MS Sans Serif;}}
{\*\generator Riched20 15.0.4481}{\*\mmathPr\mwrapIndent1440 }\viewkind4\uc1 
\pard\f0\fs17\lang1033 Only four words really!
\par 
\par }
