Hi,

I'm trying to create a console-like control and would like to know if that has already been done?

I'll succeed eventually, but I would appreciate discussions about algorithms, performances and otherwise potential gotchas...

More specifically, I'm curious as to how I should design the back-end buffer and the repainting or partially invalidated areas.

Cheers.

Not sure, but wouldn't an edit control do what you need? If not, please explain further what a console application is doing for you.

Well,

basically, I need to replicate the behaviour of the win32 "ConsoleWindowClass", but without the borders and menu. Just like a console-control child window that I can host in any parent window.

For a good description of the problem, see this google thread

Unfortunately, I do not know of a way of doing that. Seems like it would involve something like CreateWindow("ConsoleWindowClass", ...), but I can't say for sure.

Depending on the specific needs you are after, an edit control can be configured to do some fairly specific things (e.g., maintain a certain size, scroll, use a fixed-spaced font).

Right,

That's why I have undertaken the task to actually implement the grunge work in a custom window class of my own.

I already have a barely functional window, which is able to resize in integral multiples of the character width and height, and that implements scrolling in a sensible way.

I'm interested in design tips in how to handle the repainting of partially invalidated areas when scrolling text and that's why my original question was targeted to how I should design the control.

Also, I would somehow need to manipulate regions of texts in order to be able to cut and paste from and to my control, so that's why such design decisions are important.

When I will need to correctly handle the colors or each character, I will probably hit some other gotchas, etc.

Cheers.

Hi,

Thanks for these articles.

I will need this information in the latter part of my project, but that's not exactly what I need right now, however.

Cheers.

Changing item height in CListCtrl is not supported by control behaviour. But there is an indirect method of doing so. For this, first of all, set the font of your control to a big size (depending on how many lines per item you need), subclass your control to handle custom draw notification messages, and paint list items yourself. That is the only way according to me.

Do you mean a file that is in the Recycle Bin, or a file that is truly deleted?

I don't know if that's what the original post was asking, but I'd like to know how it can be done with a truly deleted file Roll eyes | :rolleyes:

If it's broken, I probably did it

in the old age of MS-DOS, there was a utility program called undelete.exe.
How do you think it was working ?

It was a glorified rename utility. When a file was deleted in DOS, the first letter of the filename was changed to 0xe5. Then the marker in the FAT was flagged as "available."

Me neither, hence my question.

I've not written code to undelete files since before Windows was introduced. Given the many file systems that are available today, the way it was done back in the late 80s is no doubt different than how it is done today.

Hai friends
I mean that i u delete a file in windows it first goes to recycle bin. if u further delete it it goes.. But i think it does not goes any ware instead it is removed from the file table..
i heared that some utility did it.. Nortan had released a utility for file recovery . did u know it.

i like to do it .. that i ask any knows.. Smile | :)

i think now what i earlier said is clear

you would have to browse the entiere part of the FS on the hard disk to check the deleted file.
you would also have to watch if some sectors were your deleted file was, hadn'd been overwritten by another more recent file.
no more idea... but that's quite a hard task to do !

Can u give me some site address which provide some information related to this ? It is very useful . I found yesterday that it can be done using driver programs.

There are dozens of utilities available that can recover files on FAT16, FAT32, and NTFS file systems. Unfortunately, I know of no source code. That is a realm of Windows that I have not delved into.
