    <p>If you are on Windows XP you can simply add active content on your desktop.</p> <blockquote> <p>Right Mouse Button on Desktop -> Properties -> Desktop tab -> Customize Desktop -> Web tab -> New -> Location "www"</p> </blockquote> <p>Setup your URL and activate content. You will have a small on-desktop window with the picture from camera. If it will not refresh automatically then create a simple page with meta refresh afver 20 seconds and img tag with src property setup for your link.</p> <p>Im not sure if above works for Vista/7.</p> <hr> <p>Otherwise</p> <p>this will likely be useful to you:</p> <pre><code>'Set the wallpaper strComputer = "."

Setting the desktop wallpaper. Setting the desktop wallpaper style (centered, tiled, or stretched). Writing Registry entries. Moving a file into the wastebasket. Editing a file with the system's default editor. When the program starts (and when you click the Apply button), the program calls ReadFiles. That routine reads the names of the files in the indicated directory and saves those that end in BMP, GIF, JPG, and JPEG. After it loads all the file names, the routine calls RandomizeNames to randomize the list.</p> <pre><code>Sub ReadFiles() Dim file As String Dim ext As String ' Create the new file name collection. Set FileNames = New Collection ' Get the file names. file = Dir(DirName &amp; "\*.*") Do While file &lt;&gt; "" If LCase$(file) &lt;&gt; "temp.bmp" Then ext = UCase$(Right$(file, 4)) If ext = ".BMP" Or ext = ".GIF" Or _ ext = ".JPG" Or ext = "JPEG" _ Then _ FileNames.Add file End If file = Dir() Loop NumNames = FileNames.Count RandomizeNames End Sub </code></pre> <p>Subroutine RandomizeNames makes an array of indexes with one entry for each name in the FileNames collection. For i = 1 to NumNames - 1, the routine selects a random index and swaps it into position i.</p> <pre><code>Private Sub RandomizeNames() Dim idx As Integer Dim tmp As Integer Dim i As Integer ReDim Indexes(1 To NumNames) For i = 1 To NumNames Indexes(i) = i Next i ' Randomize them. For i = 1 To NumNames - 1 idx = Int((NumNames - i + 1) * Rnd + i) tmp = Indexes(i) Indexes(i) = Indexes(idx) Indexes(idx) = tmp Next i ' Point to the index to display. NextIndex = 1 End Sub </code></pre> <p>When a Timer fires, the program calls ShowFile to display the next file in the randomized list.</p> <pre><code>Private Sub SwitchTimer_Timer() Dim secs As Long Dim pic As Integer ' See if it's time yet. secs = DateDiff("s", Now, NextTime) If secs &lt;= 1 Then If FileNames.Count &gt; 1 Then pic = Indexes(NextIndex) NextIndex = NextIndex + 1 If NextIndex &gt; NumNames Then RandomizeNames ShowFile FileNames(pic) End If NextTime = DateAdd("s", Pause, Now) secs = Pause End If If secs &lt;= 60 Then SwitchTimer.Interval = secs * 1000 Else SwitchTimer.Interval = 60000 End If SwitchTimer.Enabled = True End Sub </code></pre> <p>Subroutine ShowFile checks the Style combo box and sets Registry entries to make the desktop image centered, tiled, or stretched. Next, if the file is a bitmap file, the program simply calls the SystemParametersInfo API function to set the desktop background image.</p> <p>If the file is not a bitmap file, the program loads it into a hidden PictureBox and then saves the image as a bitmap file. Then it calls SystemParametersInfo.</p> <pre><code>Private Sub ShowFile(ByVal file_name As String) Const STYLE_CENTERED As String = "0" Const STYLE_TILED As String = "1" Const STYLE_STRETCHED As String = "2" Const TILE_NO As String = "0" Const TILE_YES As String = "1" Dim had_error As Boolean ' Set the display style. had_error = False Select Case cboStyle.Text Case "Centered" If SetRegistryValue(HKEY_CURRENT_USER, _ "Control Panel\Desktop", "TileWallpaper", _ TILE_NO) _ Then had_error = True If SetRegistryValue(HKEY_CURRENT_USER, _ "Control Panel\Desktop", "WallpaperStyle", _ STYLE_CENTERED) _ Then had_error = True Case "Tiled" If SetRegistryValue(HKEY_CURRENT_USER, _ "Control Panel\Desktop", "TileWallpaper", _ TILE_YES) _ Then had_error = True If SetRegistryValue(HKEY_CURRENT_USER, _ "Control Panel\Desktop", "WallpaperStyle", _ STYLE_TILED) _ Then had_error = True Case "Stretched" If SetRegistryValue(HKEY_CURRENT_USER, _ "Control Panel\Desktop", "TileWallpaper", _ TILE_NO) _ Then had_error = True If SetRegistryValue(HKEY_CURRENT_USER, _ "Control Panel\Desktop", "WallpaperStyle", _ STYLE_STRETCHED) _ Then had_error = True End Select If had_error Then MsgBox "Error saving desktop style to registry.", _ vbOKOnly, "Registry Error" End If ' Display the file.

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.
