用DELPHI压缩ACCESS数据库

uses dao97,dao2000;   //引用这两个单元

{使用本函数时调用
CompactMdbDatabase('数据库原路径','数据库目标路径','旧密码','新密码',是否是97的数据库) }

procedure CompactMdbDatabase(srcDbname,dstDbname,oldpwd,newpwd:string;bAccess97:boolean=true);
var idbEngine:_dbEngine;
begin
if oldpwd <>'' then oldpwd := ';pwd='+oldpwd;
if newpwd <>'' then newpwd := ';pwd='+newpwd;

if bAccess97 then
begin
idbengine := CreateComObject(dao97.CLASS_DBEngine) as _DBEngine;
idbEngine.CompactDatabase(srcDbname,dstDbname,newpwd,dbVersion30,oldpwd);
end else
begin
idbengine := CreateComObject(dao2000.CLASS_DBEngine) as _DBEngine;
idbEngine.CompactDatabase(srcDbname,dstDbname,newpwd,dbVersion40,oldpwd);
end;
end;
