Have you first called CWnd::EnableToolTips(TRUE)? And since your dialog is not derived from CFrameWnd, tool tips for your edit control will not display correctly unless you provide a handler for the TTN_NEEDTEXTW and TTN_NEEDTEXTA notifications.

hi all,

I am creating application that reads data from file and again save the updated data to file. I don't want users to modify the saved file outside the application. If somebody does so, the file shouldnot be opened by the application that I have developed.
can anybody help me.

I'm not certain I understand this :

Why can't you simply use a binary format that only your application knows ? if someone else wants to mess with the file, why would your application care if they manually screw it up ?

If the file was modified by someone else, why do you not want to be able to open it with your own application ???

Did you try querying the interface for IPicture? Also, I didn't see any code for getting pElemDispatch from pColl.

hi.. my program is about to capture the dektop by creating compatible dc and compatible bitmap and than convert it from ddb to dib. But I want to compress it before storing it in DAT format. How to proceed with this

   Since you mention a specific format (DAT), it is unclear if you mean that you want to scale the image before storing it, or if you really mean data compression.

   Scaling can be done in a coarse fashion by drawing the image to a target DC with reduced target width and height values. GDI+ offers functions that may make a better quality image, as will a dedicated graphics library.

   If you really mean data compression, which should happen after the image is first converted to its target format (DAT?), then you can use a library like ZLIB[^].

   Lastly, if you meant tape backup (or other offline/removable storage) when you said "DAT", then ZLIB helps there, too.

   Peace!

Hi guys
i want to detect Floppy arrival but 'WM_DEVICECHANGE' does not work for floppy so is there anyway to detect Floppy arrival.

Actually Floppy Drive doesn't work the way CD Drive work. I mean, you could simply put Floppy in the drive, but to make Computer aware you have to click on floppy icon, which is not in case of cd drive. thats just my logical conclusion!

I think its not good way but he can uses of SetCurrentDirectory check return value if its nonzero it has floppy.

But you have to poll regularly for that.. i don't think thats good design and could present user headache, as if floppy is corrupt, it could hang the system!
