VB.net中代碼如何寫，當(dāng)選中文本為粗體時(shí)單擊按鈕變成正常的，反之變?yōu)榇煮w，其它不要變？
vb.net 沒用過，不過估計(jì)richtextbox控件應(yīng)該有selbold這個(gè)屬性
If RT1.SelBold = False Then
RT1.SelBold = True
Else
RT1.SelBold = False
End If
這樣就行。如果沒有這個(gè)屬性就不會了
vb將選中文字加粗怎么弄
其實(shí)純粹的文本框是不支持選中文本標(biāo)粗的，你應(yīng)該使用richtextbox控件。
文章標(biāo)題：vb.net不選中加粗 vba加粗
