问题描述

当数据以自动换行显示形式填充静态文本或在mfc中不使用自动换行属性时，如何清除静态文本数据?

假设有文字说
1 2 3 4 5和

当下一个6到来时，它应该擦除1，并且文本中的数据应为

2 3 4 5 6

当下一个7到来时，它应擦除2，并且文本中的数据应为

3 4 5 6 7

而且我也想更改最近输入的字符的颜色，例如6，然后当7变为6时为正常颜色，而7应更改颜色

推荐答案

静态或非静态-与问题无关(如果您正确理解了什么是静态的). "MFC"可能意味着使用类CString，请参见:
http://www.cppdoc.com/example/mfc/classdoc/MFC/CString.html [ ^ ].

CString::Delete(int nIndex, int nCount = 1)可以使用的功能.

Static or non-static — it''s irrelevant to the question (if you understand what is static correctly). "MFC" probably means using the class CString, please see:
http://www.cppdoc.com/example/mfc/classdoc/MFC/CString.html[^].

The function you can use if CString::Delete(int nIndex, int nCount = 1).

如果要更改颜色，请使用RichEdit控件，在该控件中，您可以为锁符指定不同的颜色.参见 [

if you want to change the colors use RichEdit control, in which you can specify different colors for chracaters. see [^]

d++; //here count the number of displayed characters
if(d==28)// my static text control 28 characters fills the length of its display
{
m_Keys.dischords.Empty();//when it reaches limit empty the text
d=0;//start again from first count
}
displaychords(m_Keys.dischords);
