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;
