    <p>Some time ago we were doing something similar, and we found that when RDC is minimized, the remote desktop session is not redrawn or accept keys or mouse events. Everything was working fine until we minimized the RDC screen. A colleague found out that this is done for performance reasons.</p> <p>Some days ago I stumbled upon this, but I haven't had the chance to try it. If you try and it works, please let me know :)</p> <p><a href="http://smartbear.com/support/viewarticle/18731/" rel="nofollow">Interacting with remote desktop when RDC is minimized</a></p> <p>Regarding your comments: I think this is another kind of issue... I understand that you need your application to work even if no one is logged into the machine. I've implemented services that are allowed to interact with the desktop, for example, to launch an application and automate it. Even no one is logged in the machine, you can still manipulate the UI, for example, with an UI automation library (or your code, I assume).</p> <p>After starting the machine, when my service and automated application are running everything works fine. Later on, the UI being automated will appear on the desktop of the first person who logs in (I was a machine administrator, I don't know what will happen when somebody with less privileges logs in).</p> <p>I don't know what will happen if the first login is done through RDC. Maybe you could try changing those RDC settings id this affects the behavior of your application. Another option is:</p> <ol> <li>Disable RDC and configure windows to Autologin with an specified account</li> <li>Connect to this machine using another remote desktop application (e.g. TightVNC)</li> </ol> <p>Does this help?</p>

    1. COThis is interesting and it looks like it will work but I need it to work such that I don't even have to remote in and my application can continue running as a SYSTEM user and still take screenshots. I'm sure there must be a setting on the remote machine to allow applications to make use of the GUI even when no user is connected!

    2. CO@Kay- Regarding my edition: We have some 'worker' virtual machines to perform this kind of work, like UI automation. I have been interacting with the UI even no one logged in. However, you have to take care with people logging into the workstation. My RDC disabling and autologin is a proposed solution for this. However, as the VM we use are under our control, we don't need to implement anything strategy to control people logins, as no one is able to use these machines. If you are in the same situation probably you don't need to do anything else than creating the service and launching you app.

    3. CONormally you should be able to create new desktops beside desktop-0 (The login one) and the user or RDC ones to do this. But I don't know how GDI drawing code will act there.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
