This precompiled header setting isn't a per-project setting. Set it to "Use Precompiled Header" in the project and inherit this setting in all your .c and .cpp files. After this open the properties windows individually for your stdafx.cpp file and set its precompiled header setting to "Create Precompiled Header". The next step is to select all .c files and open the properties window for them and set the precompiled header setting to "Not Using Precompiled Header". Make sure that you don't include stdafx.h in your .c source files.

thank you pasztorpisti for your reply.
i configured my project to release mode from Configuration Manager and did what you earlier suggested. it builds without errors but when i run exe file, one of the serial ports does not open and gives error 0x7B (system error code). it runs fine (both serial ports open) when build in debug mode. any idea what is happening?
Regards
Jawad

That's a bug in your code or one of the libraries you use.

sorry, i didn't understand. what kind of bug we are talking about? i didn't understand the reason behind this. can you please tell me why this behavior is happening (i.e running fine in debug mode but in release mode, opens one port and not the other)?
Regards
Jawad

There are many reasons for a buggy program to behave differently in debug/release mode. For example code optimization can sometimes screw up your code even if its otherwise non-buggy. Fortunately visual C++ is quite safe in this regard so I wouldnt search for something like this. The most dangerous difference between release builds is memory management/allocation. Debug builds use special values to fill up your stack/heap memory areas when they are allocated to detect programming mistakes (like when you try to use uninitialized variables). This fill doesn't happen when you run your program in release mode resulting in different behavior. Another problem is that even if your build is in Release mode the allocated memory is filled with zeros (not the same value as in debug builds) if you start your executable from your ide by debugging it! For this reason sometimes the bug occurs only if you start the exe from outside your IDE and then attach to it with your debugger. I would search for some uninitialized variables/members...

Delete the .pch file, it's not a source file.

If all source files are in a single project then change the .c files to .cpp and try building again.

Legacy source might not compile that way and its constant hassle to upgrade some 3rd parties that come in .c files.

I know, I have been through similar exercises in the past, but sometimes it just needs to be done.

Hi,
How do I download/copy a file from a remote drive to my local drive. I know the use of API "CopyFile" but what I would like to accomplish is download a big file ~20Mb in packets of 4096bytes. Please help...

Use file I/O, reading and writing one block at a time; see CreateFile()[^] and associated functions.

Please do not ask for complete code. Converting characters to hexadecimal representation can be performed quite easily with either the printf()[^] or cout[^] functions. Neither of which has anything to do with MFC.

I think only admins can do that. Strange really, since you and I can edit questions in the Q&A section.

MS offers free versions of its developer IDE, "VisualStudio" called "Visual Studio Express". It comes with tutorials and Application wizards that help you create a simple dialog based application with just a few mouse clicks.
Note that you can get other free developer suites from different vendors; I suggested VisualStudio because you asked about MFC. Other vendors may not offer much help about MFC.
Also note that you shouldn't invest a lot of time in learning MFC unless you have to. It's antiquated, has some horrible artifacts in its API that should have been fixed 15 years ago, and it's long been replaced with .NET, and now Metro. There are also other libraries with the same functionality as MFC or .NET, some of them free.

Please help, i don't know how to get coordinates when a user click on an image.
|
|
|
|

You get them in the parameters provided with the WM_LBUTTONDOWN[^] message.

+5, You might be right but the problematic part can easily be the position of the image that is drawn with whatever method...
|
|
|
|

Well obviously knowing the co-ordinates of the image is a pre-requisite, but as with so many questions there is a serious lack of detail.

What kind of image? What kind of coordinates? Without the context its impossible to answer your question, please be a bit more specific!

All these packets are to be loaded on cars. The cars are lined in order, so that the packet could be loaded on them. The cars are also named [A, B, C, D, E,………….]. Each Car will load the packet with the same alphabet. So, for example, car ‘A’ will load all the packets with name ‘A’. Each particular car will come at the loading point only once. The cars will come at the loading point in alphabetical order. So, car ‘B’ will come and take all the packets with name ‘B’ from the shelf, then car ‘C’ will come. No matter how deep in the shelf any packet ‘B’ is, all of the ‘B’ packets will be displaced before the ‘C’ car arrives. For that purpose, some additional shelves are provided. The packets which are after the packet B, are kept in those shelves. Any one of these shelves contains only packets, having the same name. For example, if any particular shelf is used and if a packet with name X is in it, then only the packets having names X will be kept in it. That shelf will look like [XXXXXXX]. If any shelf is used once, then it could be used again only if it is vacant. Packets from the initial shelf could be unloaded from top only. Write a program that finds the minimum total number of shelves, including the initial one required for this loading process.

No, that is what you are supposed to do; this site does not provide on-demand solutions to homework questions.
