总结
- 有inputbox，就需要msgbox("你好")
- 设置标题可用
id.属性、form.属性、me.属性、me.form.属性
- 时间可用
date、date()、now、now()
- 先看有没有定义，有定义用定义
- 设置标签颜色
id.fontColor = vbred、id.fontColor = rgb(255,0,0)、me.id.fontColor = vbred
- Select没有匹配的就执行
Case Is >= 3
- 窗体数据来自表(tStud)中的数据：
fDetail.Form.RecordSource = "select * from tStud;"
- 设置窗体背景图片:
Picture = CurrentProject.Path & "\test.jpg",Picture = CurrentProject.Path + "\test.jpg"
- 指定窗体的数据源
Form.RecordSource = "formName"
- '提示框有“是”和“否”两个选项
MsgBox "报表预览", vbQuestion + vbYesNo, "确认"
- 获取用户的点击:
a = MsgBox("报表预览", vbQuestion + vbYesNo, "确认"),If a = vbYes Then
- 只有确定按钮
MsgBox "请重新输入口令！", vbOkquit、MsgBox "请重新输入口令！", vbOkOnly
- 有
inputbox,就有msgbox "你好"
Trim删除字符串前面和后面的空格:Trim(tText.Value) & "等级考试测试"- 判断表中是否有相同的数据:
name.EOF、not name.EoF
- '将光标移到tUser处:
tUser.SetFocus
- 禁用按钮:
CmdSave.Enabled = False、 CmdSave.Enabled = True
- 标题为粗体:
Me.id.FontBold = True、Me.id.FontBold = False
- 运行宏:
DoCmd.RunMacro "MacroName"
- RecordCount返回rs中的记录条数：
rs.RecordCount
