Invalid Blob handle in record buffer

不想掉头发的萌新 2022-06-20 16:33:02

Delphi7使用DBGRID时有一列显示(MEMO)

搜索后推荐使用DBGRIDEH进行解决

但是现在报错Invalid Blob handle in record buffer

看到他们都说设置

Blob size必须设置成2的整数倍,如32,64,1024等等,另外blob cache最好设置成blob size的两倍。

 

但是现在我不知道如何更改这个设置

有没有好心的大佬帮忙指点一下

1、不使用DBE,用ADO就不会有这问题;
2、Blob size的修改是在注册表里,SOFTWARE\Borland\Database Engine\Settings\DRIVERS\PARADOX\TABLE CREATE键值下。你也可以直接注册表搜索关键字。
