VB6.0 with Registered OCX control

[vhassan]

hi. Thanks for previous replies. I have registered control under Administrator privileges on window xp OS. My application use that control and it works fine. I use check if ocx control registered on machine then run otherwise show appropriate message. Now I have guest account (limited privileges) and I am unable to read/write registry values. So my application found no control registered and loads nothing. I want my application to show ocx control because it is already registered by administrator. Please tell me how can I access registered controls. Also tell can I use COM components in this regard?

I already told you, the only way to can find out if the control is registered is to NOT use the designer to drop the control on the form. You can only see if the control is registered if you use CreateObject to try and create an instance of the control. You can catch the error by running the CreateObject code right after an On Error Resume Next line and checking for the value of Err.Number.

Ditto to Dave, quit asking the same question every day. If you need additional help, reply to your previous post.

Respected replier. I am using RegOpenKeyEx(KeyRoot, KeyName, 0, KEY_ALL_ACCESS, hKey) to open registry key and check whether control is registered or not. Problem is that when I open registry from guest account I always get 5 return code instead of SUCCESS 0. Thank you.

I already told you, in your other post, that the Guest account has no rights to anything. The only part of the registry it can read in under CURRENT_USER, which won't have the component registration info.
