[Database system] 222 DL : 0: 这是在学习数据库时写的一个程序，采取DAO访问ACCESS数据库的方式 1：在程序中使用了CButtonStyle这个免费类库。 2：在InitButtonSytle()中，为了使代码更短小，用循环实现了位图按钮。 // 用循环实现必须手动改动Resource.h中的定义 // 具体细节请参看源代码 for ( int nIco = IDI_JUMP, nBtn = IDC_JUMP nBtn >= IDC_LISTITEM nIco--, nBtn-- ) { CButtonStyle *Button = ButtonList.RemoveTail() Button->SubclassDlgItem( nBtn, this ) Button->SetIcon( nIco ) Button->SetInactiveBgColor() Button->SetInactiveFgColor() Button->SetActiveBgColor() }-This is in learning to write a database procedure, visit the ACCESS database DAO take way 1: in the procedure used CButtonStyle This free class library. 2: InitButtonSytle () in order to make the code more short cycle achieved using bitmap button.// Use recycled Resource.h realize changes must be manually defined in// the specific details please see the source code for (int nIco = IDI_JUMP, nBtn = IDC_JUMP nBtn
