There is no such control in vs2005, you need to register, the steps are as follows:
1. First go to the C:\WINDOWS\system32 directory to see if your system has Msadodc.ocx and msdatgrd.ocx these two files (mostly not), do not download;
2. Register both the Msadodc.ocx and Msdatgrd.ocx controls in vs 2005. In VS 2005 Click on "Tools"--"Visual Studio 2005 Command Prompt", enter the following command:
regsvr32 msadodc.ocx
regsvr32 msdatgrd.ocx
Now go to Insert ActiveX contrls look, hehe, is not there a Microsoft Ado data control and Microsoft Data Grid control two new faces AH? OK, now you can use them in the project. In addition, I wrote the two controls are 6.0 versions, as early as VC + + 6.0 when they have appeared, but at vs 2005 can also be used normally. As for the later versions or other ADO controls that may exist, you can try to add them yourself.
