Help: unwanted undo-checkout in sourcesafe

[codism]

I lose my work by a mistaken clicking on "undo check out" and confirming. Is there any way to find my modifiction back? Tons of thank for any idea.

No. If you do Undo Check Out, then you did not CheckIn.
That means that the only computer with the updated file (before the undo) is your computer. When you confirmed the "lose changes" message then your file gets overwritten by SourceSafe, and your copy is gone.

Unless you did a backup before undo check out somewhere else...
