大佬教程收集整理的这篇文章主要介绍了[VB.NET]Fill:SelectCommand.Connection property has not been initialized,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
Fill:
SELEctCommand.Connection property has not been initialized Dim dbCommand As Syste
m.Data.IDbCommand = New Syste
m.Data
.oleDb
.oleDbCommand Connection.Connection
String = Provider=Microsoft.
jet
.oLEDB.4.0;Data
source=|DataDirectory|/homeautosy
s.mdb Connection
.open() DataTab_LightOff.Clear() Dim dataAdapter As Syste
m.Data.IDbDataAdapter = New Syste
m.Data
.oleDb
.oleDbDataAdapter dataAdapter.
SELEctCommand = dbCommand Dim DataAdapter_LighOff As Syste
m.Data.DataSet = New Syste
m.Data.DataSet command_LightOff =
update [Lights] set [Off_On]= Off Where ( [Lights].[Room_Name]= Bedroom One ) DataAdapter_LightOff = New Data
.oleDb
.oleDbDataAdapter(command_LightOff,Connection) dataAdapter.Fill(DataTab_LightOff) 这是源代码,
编译的时候出现错误:Fill:
SELEctCommand.Connection property has not been initialized 这是什么原因?该怎么改? 是在移动页面上做的 目的是实现点COMMAND的控件,然后数据库中中BEDROOM ONE的那行的OFF_ON列对应的值变为OFF 如果上面的方法不对,最完写完整的另外的代码! __________________________________________________________________________ dbCommand.CommandText =
SELEct *.... ; 需要指定。 __________________________________________________________________________ Connection.Connection
String = Provider=Microsoft.
jet
.oLEDB.4.0;Data
source=|DataDirectory|/homeautosy
s.mdb Connection
.open() Dim dbCommand As Syste
m.Data.IDbCommand = New Syste
m.Data
.oleDb
.oleDbCommand(
update [Lights] set [Off_On]= Off Where ( [Lights].[Room_Name]= Bedroom One ) ) dbCommand.Connection=Connection dbCommand.ExecuteNonQuery __________________________________________________________________________
