如何从VB6中的xBase/Clipper文件中读取数据? DBF文件位于C:\dbase\clip53\PRG\stkmenu\WPACK3\ DBF文件被称为WPACKS.CFG(故意不是.DBF)
ActiveX EXE中用于打开数据库和记录集的VB6代码:如何从VB6中的xBase/Clipper文件中读取数据? DBF文件位于C:\dbase\clip53\PRG\stkmenu\WPACK3\ DBF文件被称为WPACKS.CFG(故意不是.DBF),vb6,adodb,clipper,xbase,Vb6,Adodb,Clipper,Xbase,ActiveX EXE中用于打开数据库和记录集的VB6代码: Function OpenDatabase(sFile As Variant, Optional sProvider As Variant = "Provider=Microsoft.Jet.OLEDB.4.0") As Variant ' ADODB.Connection Dim nErr As Long Dim sErr As String Dim oConnection As Object 'ADODB

我的问题是我一直得到连接无法用于执行此操作。它在此上下文中是关闭的或无效的。
当它点击oRecordSet.open sQuery,,adCmdText时(我从Microsoft站点获得)
这有点令人恼火。尝试使用最新和最好的FoxPro驱动程序。尝试使用最新和最好的FoxPro驱动程序。我需要连接DBF文件时使用的连接字符串通常类似于:
"Driver={Microsoft dBase Driver (*.dbf)};dbq=<filePath>"
“驱动程序={Microsoft数据库驱动程序(*.dbf)};dbq=”
它对我来说很好。我需要连接DBF文件时使用的连接字符串通常类似于:
"Driver={Microsoft dBase Driver (*.dbf)};dbq=<filePath>"
“驱动程序={Microsoft数据库驱动程序(*.dbf)};dbq=”
它对我来说很好。或者使用FoxPro提供程序,这样你就不必通过ODBC提供程序或丢失FoxPro提供的增强功能。或者使用FoxPro提供程序,这样你就不必通过ODBC提供程序或丢失FoxPro提供的增强功能。
