Question

Dear All,

I've created an MFC ActiveX control to use in web based application. In that ActiveX control, there is a method to create a folder in a selected drive e.g. (C:\MyFolder\Folder1). This ActiveX(.ocx) is working fine if i try to create the folder from HTML page (which is in local PC ) in both windows XP and windows7.

But the same not working in windows7 when HTML page is loaded from the server. It is giving error code 5 (by using GetLastError()) .

Any help is appreciated, thanks in advance.

On Windows 7 such an operation is not allowed to standard user code. You have to run your application 'as administrator' or programmatically elevate the application level of execution (there are articles here at CodeProject about it, see, for instance: "Riding the Vista UAC elevator, up and down"[^]). Or you may, simply, create the folder in a less 'protected' place.

Thank you Pallini.

But if i use same code as a standalone mfc application its working. But while using this code in an ActiveX control used by web browser to create directory its giving error.

So cannot understand what to do?

See the additional notes from jack and myself.

Your browser has different UAC permissions. Your ActiveX control inherits the brower's permissions. CPallini's note will lead you to the answer. You need to programmatically elevate the controls permissions, so that it can create folders.

You should have replied to cpp_com instead of posting a comment to cpallini.

This sounds like the problem... I would recommend moving the file to a location that Win7 is ok with since these permission schemes aren't going away and you really don't want to make your user be an admin unless he absolutely must be. +5
