    <h2>BACKGROUND</h2> <ul> <li>I am writing a screen capture application</li> <li>My code is based derived from this project: <a href="http://www.codeproject.com/KB/cs/DesktopCaptureWithMouse.aspx?display=Print" rel="noreferrer">http://www.codeproject.com/KB/cs/DesktopCaptureWithMouse.aspx?display=Print</a></li> <li>Note that the code captures the the mouse cursor also (which is desirable for me)</li> </ul> <h2>MY PROBLEM</h2> <ul> <li>Code works fine when the mouse cursor is the normal pointer or hand icon - the mouse is rendered correctly on the screenshot</li> <li>However, when the mouse cursor is changed to the insertion point (the "I-beam" cursor) - for example typing in NOTEPAD - then code doesn't work - the result is that I get a faint image of the cursor - like a very translucent (gray) version of it instead of the blank &amp; white one would expect.</li> </ul> <h2>MY QUESTION</h2> <ul> <li>How can I capture the mouse cursor image when the image is one of these "I-beam"-type images</li> <li>NOTE: If you click on the original article someone offers a suggestion - it doesn't work</li> </ul> <h2>SOURCE</h2> <p>This is from the original article. </p> <pre><code> static Bitmap CaptureCursor(ref int x, ref int y) { Bitmap bmp; IntPtr hicon; Win32Stuff.CURSORINFO ci = new Win32Stuff.CURSORINFO(); Win32Stuff.ICONINFO icInfo; ci.cbSize = Marshal.SizeOf(ci); if (Win32Stuff.GetCursorInfo(out ci)) { if (ci.flags == Win32Stuff.CURSOR_SHOWING) { hicon = Win32Stuff.CopyIcon(ci.hCursor); if (Win32Stuff.GetIconInfo(hicon, out icInfo)) { x = ci.ptScreenPos.x - ((int)icInfo.xHotspot); y = ci.ptScreenPos.y - ((int)icInfo.yHotspot); Icon ic = Icon.FromHandle(hicon); bmp = ic.ToBitmap(); return bmp; } } } return null; } </code></pre>

    1. COI had a similar problem once, we were making automatic screen capturing for app documentation. But instead of using interop to get the cursor, I simply used my own cursors (in .png files). It was much simpler and we were able to get nice transparency effects (pointer shadow and stuff).

    3. CORegarding dimitar **CaptureScreen** Use DrawIconEx with relevant parameters to preserve captured icon dimensions otherwise, the custom mouse pointers of applications will be scaled down to system pointers sizes. e.g. go to Power point and make the presentation, enable pen pointer Take the screen capture with mouse - you will see this mouse cursor weird. In case of more than 2 monitors(Extended monitor) this methods captures TOTALLY TRANSPARENT image, with exception of the custom mouse cursors that are drawn OK.

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.
