Are you using Visual Studio 6 or .Net 2003

How we calculate the size of Jpeg image(not dimension),to recover the image if our system is formatted and the Original information about the size is Corrupted.

Whats the meaning of size?

Actually we want to find out the size of jpeg file in the compressed form.Because when we recover deleting JPEG file some time it is possible that the header cotaning information about size is cruptted then what we do in that case to calculate the size so we recover this jpeg file.

:|Hi all,
I want to know in an application the ID of the current mouse cursor at
any moment. I got the handle to the current cursor on server
machine and want to inform the client that cursor shape is changed
so that client can also reshape its mouse cursor.
Can i send the handle of the cursor on server to the client and
use that handle to reshape the cursor?
If not then how can i get the ID of the cursor from handle?
or any other way to do that.
Thanx

What the <blank> are you talking about. The mouse cursor belong to no application, unless it has captured it. It belongs to the system. Therefore it does not have or require an ID.

Hi,
I am coding for a project in which it is required that I draw circles of certain radius over a scanned map (saved as a bitmap) and then save the changed map.
I know how to display a bitmap. I also know how to make an independent drawing and save it as a bitmap. But how do I do both – open an existing bitmap, draw over it and then save it? Please give me some idea.
Thanks,
Tara

Hi
There are many ways to do. I am just giving one of the way. Don't know how efficient it is. Since a long back I left programming of bitmap.
any way lets try.
1. Create a CBitmap member;
2. Draw to DC as you are doing the image and the circle.
3. Explore the DrawState funtion of CDC class. i.e use this funtion to link between your DC and CBitmap.
4. Then convert the CBitmap to DIB.( you will get lots of article on net / CP )
5. Once you get hte DIB you won't have any problem to save it.
Regards
Anil

If you know how to do "...an independet drawing and save it as a bitmap". Then you already know the answer to your quesion.
Which bitmap are you saving? The one before you drew on it or the one after you drew on it.

Well, actually I learnt how to make a drawing on to a dialog box and then save the drawing as a bitmap from CodeProject. So I know how to save a drawing as bitmap.
What I want to do is:
1) Display a bitmap when the user opens it(ie. the user opens the bitmap eg. map of an industry)
2) Ask the user to click the mouse on a certain point on the bitmap
3) using that point(x and y coordinates), I do some calculations and get the correct radius.
4) Then I display to the user a circle of the calculated radius around that point on the map.
5) If the user selects 'save', I must save the whole thing i.e. the map with the circle on it, as a single bitmap.
I hope I am stating my problem clearly...
I tried creating a dc to hold the bitmap which the user opens and using the same dc, i tried to draw a circle on the bitmap... but it dosent work.
Your help will be highly appreciated. Thank you.

Try studing the
Memory bitmap class CMemBm[^]
The basic steps are:
1. Create a compatible DC. Lets call it memDC.
2. oldBitmap = Select your bitmap into memDC.
3. Draw on memDC.
4. Select oldBitmap into memDC.
The bitmap should now have whatever you drew on it. To test that it does, blit it to your client area.
If you drew on a bitmap, say using the mounse, in the client area. Then you need to get a copy of the bitmap from the client area. In order to do that you must know the client coordinates where the bitmap is located.
1. Create a compatible DC. Lets call it memDC.
2. Create a compatible bitmap, that is the same size as the area that you want to copy. Lets call it tempBitmap.
3. oldBitmap = Select your tempBitmap into memDC.
4. Bit blit the rectangular area from the client DC to the memDC.
5. Select oldBitmap into memDC.
6. Finish cleaning up.
Now tempBitmap should contain a copy that matches the area of the client you specified. To test it, just clear an area of the client and blit the tempBitamp there.
I hope that helps.

Thanks John.
I am going to try it. Hope it takes me only few days and not weeks to finially get it. Bitmaps, somehow seem to be beyond my understanding...
Thanks again.
Thank you, Anil too for your suggestion.

Hi!
I am a new member to code project and this is my first message to the forum. I am a 6th sem MCA student doing my project work in a company as part of my academic curriculum.Presently i am working on a software related to GUI testing. I am using some MFC application exe files for this purpose. My problem is that some of the exe files i am using end up with errors at the runtime. So it is my request to every member of this forum to please suggest me as to how i can get the source code of an MFC application after it is converted to exe format.

Try to open the file in notepad
if that doesn't work try to get in touch with the original coder and take him out to lunch 
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

Have you tried contacting the original developer of the application and asking them *very* nicely - you never know they might be feeling generous and let you have it... 
There is no pratical way of decompiling an exe built with c++ (something which I'm thankful of as it would probobly put me and many others out of business.) The closest your going to get is an assembly dump of the code - something which I'm guessing isn't what your looking for.
If you've got a problem with the application, contact whoever wrote it.

actually, he could decompile an exe into C/C++ code if the exe were built in debug mode...
but i doubt the guy who's asking the question wants to decompile such a thing but a release exe.

Even in Debug mode I didn't think it was possible to decompile it into anything particulary useable, but hey I could be wrong...
