I created a new Visual C++ project of type MFC dll and added several source files to it. In Debug mode they all get compiled but in release mode only one particular source file gets compiled even though all the source files are listed. If I remove all else and keep any one particular source file then that gets compiled. Thinking I might have done something wrong I even recreated the project from scratch, and still face the same problem. I haven't seen anything more bizarre than this. I'm using VS 2008 Pro. Please help before I shoot myself.

Installshield professional for 2008
Hi
I am migrating my application from vc++6.0 to vc++2008
When application was build in vc++6.0 successfully i created the package using intallshield professional for vc++6.
Now my application is working fine in vc++2008 with no errors. I need to know wether i can use the same installshield to build the package , or there is any new version available for 2008.
Thanks

DLL with wrong missing symbols
I have a program (mrViewer) which uses the ffmpeg libraries built from zeranoe together with a bunch of other libraries. This program was compiling and running just fine. However, now it no longer is so. My problem is weird. I compile and link my program without any problem. However, when the executable is run, it complains saying __glutInitWithExit is missing in avcodec (one of the ffmpeg libraries). Now I know for sure that ffmpeg does not link with glut at all. When I run dependency walker I indeed see 3 functions undefined in avcodec (functions found in the glut library). If I use dependency walker in the glut library (freeglut btw), it shows the functions defined just fine. If I change the order of the linked libraries, sometimes the warning is different, which puzzles me more.
So I am at a loss on what to try to get my program back to working. Something in the build process is broken, but I cannot tell what.
My program is mrViewer which can be found in sourceforge at sourceforge.net/projects/mrviewer

VIsual C++ 2012: Can you compile MFC DLL/Library from source code?
I am curious if it's possible to compile the MFC source code to DLL/Library from what is provided with the Visual C++ 2012 install.
If so, where would I find this information?
Hoody Hoo!

GSM based Tracking
Hi Everyone,
I am developing Geo-Tracking application. I am tracking device based on different methods like:
Tracking based on IP address, Wi-Fi, GPS, GSM
I want to implement tracking based on GSM. I am using VC++.
Please suggest me any third party library available or windows API, using which I can implement my Geo-Tracking based on GSM.
Thanks in Advance,

Overloading exported functions in C++ DLL
I currently have a .def file
LIBRARY "MyLib"
EXPORTS
Foo
and code
int __stdcall Foo(int a);
1) can I overload this?
I'm told that I must instead use
#define DllExport __declspec(dllexport)
int DllExport Foo( int a ) {
// implementation
}
int DllExport Foo( int a, int b ) {
// implementation
}
but some platform docs say "The DLL must export functions using the __stdcall calling convention"
2) can anyone tell me if there is an important difference between the two?

What is this dreaded __missing_type__ actually good for?
Can anybody please explain to me what this dreaded __missing_type__ is actually good for?
The compiler inserts this sort of place holder if it could not load a depending type libary before, that implements that type and issues error C4772.
When compiling these generated .tli headers afterwards, the compiler of course bails out with tons of consecutive error messages.
I have never encountered a single scenario where it makes sense to use these .tli files. What makes things worse is that Visual Studio leaves these files lying around when I do a clean rebuild. So I always have to manually delete these files if I run into problems.
Can anybody outline a situation where using a type library with missing types may produce something useful?
At some point, the description of C4772 on MSDN is actually funny:
The title says: "Compiler Warning (level 1) C4772" and then further down: "This warning is, by default, issued as an error. C4772 can not be suppressed with /W0."
ROTFL! Here's your cat! But no, your cat is actually a dog and you can't make it stop barking.
Why does Microsoft say C4772 is a warning when it's actually an error?
BTW.: Before posting, I searched technet for "__missing_type__", but since the search separates the words and counted all posts containing either 'missing' or 'type', I got 807000 hits. I didn't fell like scanning all of them....

dll UNICODE/ANSI strings
I have a dll compiled with _UNICODE
I export 2 functions:
void* foo(void* str) //returns UNICODE string
void* fooA(void* str) //returns ANSI string
if the dll host calls foo and has UNICODE or ANSI strings do I need to also consider this difference in my dll?

Class and use
Hi,
I have two pieces of code I am trying to figure out what is happening here please help@
START_CLASS // Set up a schedule pointer for each model point // Schedule pregen_bonds; Schedule *pregen_bonds; END_CLASS
pregen_bonds=new Schedule;
Then later in a different function
return pregen_bonds->getvalue(t,3) * default_sale_survival(t);
is getvalue a function in the class pregen_bonds?
What is getvalue and where does it come from? If you need more code just let me know.
Thanks

Where are the "semantics constraints for default-initialization" referred in the second bullet point of §8.5/8 (N3797)?
§8.5/8 (N3797):
To value-initialize an object of type T means:
- if T is a (possibly cv-qualified) class type (Clause 9) with either no default constructor (12.1) or a default constructor that is user-provided or deleted, then the object is default-initialized;
- if T is a (possibly cv-qualified) class type without a user-provided or deleted default constructor, then the object is zero-initialized and the semantic constraints for default-initialization are checked, and if T has a non-trivial default constructor, the object is default-initialized;
- if T is an array type, then each element is value-initialized;
- otherwise, the object is zero-initialized.

VS 2013 error LNK1104: cannot open file atlsd.lib
I'm trying

following link error: <o:p></o:p>
error LNK1104: cannot open file atlsd.lib
I've not
been able to find any references to this library in the project

I'm aware that the atl libraries have changed in VS 2013 but have not been able to figure out how to correct the link problem.

VS 2013 regsvr32 buffer too small error when registering a COM dll

Why can't I use HWND from GetDesktopWindow() to draw lines on desktop screen using Direct2D
Hello everyone,
I am working on a desktop application that is somehow related to gestures.
The goal is to draw a path or a line on the desktop screen when user performs a certain gesture.
I managed to do this using GDI+ classes but I wanted to try and use Direct2D because it renders better.
I tried using ID2D1Factory::CreateHwndRenderTarget method and passing the HWND returned from GetDesktopWindow() but I can't seem to get any lines drawn on screen.
Although when using the HWND parameter in the WndProc() method, I can draw the lines on the demo app window.
Btw, I am using the DrawRectangleExample as base code for this trial.
Is there another way to draw on the desktop screen using Direct2D?
Hoping for your opinions.
Thanks and best regards,

“Preview of ” in tab group
VS 2013 C++ sometimes opens a file with a tab at the right of the tab group instead of adding it to the open tabs at the left, and if you hover the mouse over the tab, it says “Preview of <file>” instead of just “<file>”. If you drag the tab to the group at the left, the “Preview of” part of the hover label goes away. What is the point of this? Is there different functionality involved? If not, is there a way to disable this distracting behavior?
