What's MHTML? Microsoft HTML?

Or are you talking about the "MHT"-format (Microsofts "Web Archive" -Format)?

Anyway, you will have to render the file and then save the resulting image as a BMP.

Cheers,
Sebastian

MSHTML is the "guts" of IE - A COM object which does all the HTML parsing and such.

Can anyone tell me how to capture the WM_DROPFILES message to explorer and override the default implementation for specific cases?

Thanks and Regards,
Anil

Well, you could install a hook, and handle WM_DROPFILES, and so on....

But Explorer exposes a lot of functionality for you to hook into. You could write a drop handler for the cases you are interested in, and so on.

A good place to start is the excellent shell programming series by Michale Dunn: http://www.codeproject.com/shell/[^]

Good luck,

Iain.

There's a shell extension called a copy hook that is called when the user does file operations (not just drag/drop) in Explorer. My shell extension series doesn't cover copy hooks, so check out MSDN (search for "IShellCopyHook", which is the interface name).

Actually what I need to have is the path of the folder where the drop event took place. Is there a way to find this out? In that case I wouldnt need to override the default handling of WM_DROPFILES message.

Thanks and Regards,
Anil

A copy hook extension gets this info.

1- Yes. ( must be certain that you don't write temporary files in the same path as the executable )
2- Yes. ( search this site for examples )
3- Yes. ( don't know the API, but google or MSDN can help you with that )
4- By Clicking on the Uninstall menu item ( or button in the add/remove program control panel.
5- ??? you mean by adding a shortcut of your application to the Startup folder.
6- have a look at FindFirstFile and FindNextFile
7- don't have a clue.

From the previous answer you can see that what you are asking is possible, as I assume you are aware.

But to ask those here to do this much work for you is unreasonable.
Look around, try to do these things yourself, and when you are unable to figure something out (after trying it yourself) then ask specific questions and show what you have done, code snippets for example.

Auto deletion on reboot

Hi, I made an uninstaller, and I need to delete the uninstaller exe, and the folder where it is.

So I used

MoveFileEx((m_installDir + "UAdmPass.exe"),NULL, MOVEFILE_DELAY_UNTIL_REBOOT);

MoveFileEx, is returning OK but, I rebbot the machine and the file still there...

Any suggestions?

Thanks Big Grin | :-D

Yeap.
My application needs special permisions to delete a file?
Like when you want to force a shutdown?

I'm not sure but I think yes. But I need to check.
try with *.bat file as tell David, I think it is better.

A .bat file is going to be your best bet if you need this on all platforms. There are other solutions, but they are either limited to Windows 9x, or Windows NT, but not both. See here for more.

Check the filename - is there a backslash on the end of m_installDir?

BTW you can verify this before rebooting by looking in the reg key HKLM\SYSTEM\CurrentControlSet\Control\Session Manager, value PendingFileRenameOperations

Thanks to all for the advise, but I need to be Win ME compatible, so I'll use a .bat file Big Grin | :-D
