    <p>I am writing a kiosk application which has 6 displays hooked up to 1 PC with 2 3 headed cards. The displays are capable of only one resolution 1024x768. For whatever reason Windows 7 detects them as displays with a resolution of 1600x1200. The desktop area must be arranged is such a way that display 1 is on the left and 6 is on the right in sequential order. This is a simple solution to solve in the lab by simply using the windows display control panel to rearrange the desktop by hand. In the field after I deliver the software to drive the kiosk this will not work as windows will rearrange the desktop and resolution if say a display fails and is replaced. My software is required to programmatically arrange the desktop and resolution.</p> <p>In a perfect world I'd like to be able to make a series of win32 calls that I could wrap in a function to perform:</p> <pre><code>Set the resolution of display plugged into video card 0 port 0 to 1024x768 Set the workspace position of display plugged into video card 0 port 0 to 0,0 Set the resolution of display plugged into video card 0 port 1 to 800x600 Set the workspace position of display plugged into video card 0 port 1 to 1024,0 Set the resolution of display plugged into video card 0 port 2 to 1600x1200 Set the workspace position of display plugged into video card 0 port 2 to 1824,0 Set the resolution of display plugged into video card 1 port 0 to 640x480 Set the workspace position of display plugged into video card 1 port 0 to 3424,0 Set the resolution of display plugged into video card 1 port 1 to 1024x768 Set the workspace position of display plugged into video card 1 port 1 to 4448,0 Set the resolution of display plugged into video card 1 port 2 to 1920x1080 Set the workspace position of display plugged into video card 1 port 2 to 6368,0 </code></pre> <p>Then, I would be guaranteed that port 0 in video card 0 is on the left and port 2 on video card 1 is on the right</p> <p>Does anyone have any idea how I could do this in C++?</p> <p>EDIT 1: Updated the resolutions to be a little more clear of the nature of the problem</p> <p>EDIT 2: Updated example again to include workspace portion of the problem</p> <p>EDIT 3: Spelling</p>

    2. COMy problem is slightly different because I need to specify the resolution(and workspace location) of a display based on which port it is plugged into the video card. That question sets the resolution of two monitors regardless of which port they are on.

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.
