如題~
除了放在wm_paint裏之外還有什麼方法可以用?
因為我是在主選單上新增一個功能dialog的對話框上面有edit的輸入
輸入後才要顯示文字故不能放在wm_paint
所以才想問各位先進還有什麼方法讓顯示文字不會因為移動視窗捲軸就讓文字消失??

你說的文字是放在哪?

是放在主視窗上~但我沒寫在wm_paint裏
因為我會先呼叫一個對話盒dialog
然後dialog上有一個edit輸入後才在主視窗顯示
可以調整主視窗的大小字就不見了~有什麼方法可以用呢?

在Form上放個label 應該就不會消失了吧?
你是用Canvas 寫字上去嗎?

我現在用ListView來顯示可是又遇到了一個問題
我想要當我按下ok時才跑出全部並不是一開始就建立..不知怎麼改
