Extract data from user.dmp?

I was using a tv capture application called WinTV from Hauppage.
When you press the "capture" button in WinTV, a picture is being saved in Windows memory. After that you can choose to save this file to the harddrive and delete the original from the memory.
I had made some - well, a _lot_ - captures with this application when it suddenly crashed and I hadn't saved these captures to files on the harddrive.
When it crashed this DrWatson thing was run.
I now have a 73 MB user.dmp file in my DrWatson folder. I don't know the size of this file before the crash.
Now my hope is that there is a way to extract these pictures from the user.dmp.
Is there a way?

A lot of programs create at tmp files perhaps you could see it this one did

Look in C:\Documents and Settings\YourProfile\Local Settings\Temp

First of all, when data is stored in system memory and the application that helds the data crash, is really all that data dumped to USER.DMP? Or is only *information* about the crash being appended to the file?

Is 73 MB a normal size of a USER.DMP file? Because there was a lot of picture data in system memory when WinTV crashed, like 100-150 pictures in 640x480 with no compression.

CrazyOne: I've checked for that, but no, there is no such tmp file. :-/

Stoner79: Doesn't look like this program actually can *view* the dump file? It can only check information of recent crashes, right?. But as I said, maybe the data (pictures) that was stored in system memory actually wasn't dumped to the file... If so, there's nothing I can do but give up...

sunray_2003: Same here - I don't think this program actually can view eventually data from the file...?


Before WinTV crashed, my allocating memory was at around 800 000 kb, after it terminated it was at around 500 000 kb (yes, I have a lot of applications/windows open at the moment :-) )
So the data was realased from memory, or it was stored in USER.DMP...

Argh, I really want to get back those unsaved pictures :-( But it seems like they're gone forever...

Unfortunately I think they are gone forever. It depends how the system is setup to do memory dump. It looks like yours is setup for a small memory dump based on the size of this file. If it was setup for a large memory dump then the entire contents of the memory would have been dumped and the file would be much larger then 73MB's. I got to think that those captures were more than 73MB's.
