关于线程的问题.(50分)

在非主线程中用ADO可以这样:
在线程执行中,
CoInitliaze
动态创建ADOConnction和ADOQuery.
执行ADOQuery.
释放内存
UnCoInitliaze

 
在非主线程里用类似哈欠的方法，create一个TADOdataset,在excute里完成写入access里
已经连续测试了一周了，数据库有80M,似乎没有什么问题
 
哈欠:CoInitliaze ,UnCoInitliaze 主要起什么作用呢?
我直接动态创建Ado好像也可以运行.不过当前客户数只有几个.
 
我刚做了一个类似的项目，也时多线程的，我觉得还是挺好使的。
是关于串口通讯的，其中也有ADO数据处理和BDE数据处理！

哈欠,G622:CoInitialize,UnInitialize,要使用它该引用哪个单元,帮助中找不倒相关主题.
 
to g622:uses 了activex ,依然无法识别CoInitialize
* 我是在主单元中声明了一个线程类,这样添加Activex是否只需要在住单元的uses
中加一个Activex就好了?
 
哦,我知道了是因为CoUnInitialize blue Boy写错了.
 
多人接受答案了。
