請問怎麼升级ado组件 ??? (我在用delphi 5+oracle 8.17) 謝謝, netlib(河外孤星) ,您貼出來吧!!
我的有一部分是用olecontainer的，这样写的
var
mslr,msda:tmemorystream;
begin
panel4.Enabled:=true;
n15.Enabled:=true;
mslr:=tmemorystream.Create;
msda:=tmemorystream.Create;
olecontainer1.SaveToStream(mslr);
olecontainer2.SaveToStream(msda);
clientdataset2.Edit;
clientdataset2lr.LoadFromStream(mslr);
clientdataset2lrda.LoadFromStream(msda);
clientdataset2.fieldbyname('tmm').asstring:=TabControl1.tabs[tabcontrol1.tabindex]+inttostr(clientdataset2.fieldbyname('tid').asinteger);
clientdataset2.post;
clientdataset2.applyupdates(-1);
mslr.Free;
msda.Free;
end;
用文件的，我找到了在给你看，（现在忘的差不多了）^_^
server端; ADOConnection+ ADOTable+ DataSetProvider
client端; SocketConnection+ ClientDataSet2).升级ado组件了嗎 ???
读文件是这样的，我想这个你应该都知道，
var
mslr,msda:tfilestream;
begin
panel4.Enabled:=true;
n15.Enabled:=true;
mslr:=tfilestream.Create('\temp1.doc',fmopenread);
msda:=tfilestream.Create('\temp2.doc',fmopenread);
clientdataset2.Edit;
clientdataset2lr.LoadFromStream(mslr);
clientdataset2lrda.LoadFromStream(msda);
clientdataset2.fieldbyname('tmm').asstring:=TabControl1.tabs[tabcontrol1.tabindex]+inttostr(clientdataset2.fieldbyname('tid').asinteger);
clientdataset2.post;
clientdataset2.applyupdates(-1);
mslr.Free;
msda.Free;
end;
可能是你的数据库连接那个环节不匹配造成的，所以你在检查一下你的数据库设置
client端; SocketConnection+ ClientDataSet
