Possibly, but much like porting from VS6 to VS2008, you may encounter conversion problems, though they may be fewer.

Hello,
In Visual Studio, while creating MFC application, we got Runtime Library setting in C\C++ node in Project Propery Dialog. It have different options, what is exact meaning of these.
|
|
|
|
|
Take a look at the options offered. In my system I have the following options:
- Multi-threaded : a static library that supports threading
- Multi-threaded Debug : as above, that includes debug information
- Multi-threaded DLL : a dynamic library that supports threading
- Multi-threaded Debug DLL : as above, that includes debug information
These are versions of the C/C++ basic runtime libraries, and are purely to support the language. You add extra libraries to your project to support Win32 and MFC/ATL as required. Note that most required libraries are added to your project when it is created by the New Project wizard in Visual Studio.

Hello All,
I am C++/MFC devloper. I have been working with dll/com/mfc from few years now, but I always have confusion, what is exact diffrence in Static,Dynamic,Shared library. Moreover when I use shared library it creates lib file and then I link with lib file to reuse source code.
My assumption about 'lib vs dll' was like '.h vs .cpp'. Is my assumption correct?
Wherever I work with multiple project I got huge number of linker errors.
Happy Programming.

You may find some useful information at Library (computing) page at Wikipedia[^].

It is a good analogy.

That's a practical problem that might be solved if you post the exact error message here.

I've to set the 'Loudness Equalization' property of the speakers to true. I'm referring to the MSDN DOC file (Vista_SysFX.Doc) from here[^]. But the compiler give error for CreateAudioMediaType() function saying it requires 3 parameter (prototype
STDAPI CreateAudioMediaType(const WAVEFORMATEX* pAudioFormat, UINT32 cbAudioFormatSize, IAudioMediaType** ppIAudioMediaType) ).
But when I follow this prototype, it gives me linker error for this function. Is there any SDK mismatch or version mismatch in DLLs?
Or is there any other alternative API to set the system speakers 'Loudness Equalization' property.
Thanks in advance.

I'm guessing at what your error is since you did not add the details here. Have you included the required library in your project as detailed here[^]?

|

Yes, I tried that.
The funniest part is any of the files (Mtype.h or Streams.h) isn't found when included, neither the lib. But when I change the function for 3 parameter, it gets compiled and fails to link. Even I was wondering about this prototype mismatch.

for this
hr = CreateAudioMediaType(&wfx.Format, &pAMTOut);
I get this error :
error C2660: 'CreateAudioMediaType' : function does not take 2 arguments
And when i change the code to this
hr = CreateAudioMediaType(&wfx.Format, wfx.Format.cbSize, &pAMTOut);
it gets compiled. But gives this linker error:
error LNK2019: unresolved external symbol _CreateAudioMediaType@12 referenced in function "void __cdecl useAPO(void)" (?useAPO@@YAXXZ)

Malli_S wrote: error C2660: 'CreateAudioMediaType' : function does not take 2 arguments
The doc is here[^], and the API takes 3 arguments. The last one is a BOOL, and you're passing the address of pAMTOut, which doesn't look cool.
Malli_S wrote: error LNK2019: unresolved external symbol _CreateAudioMediaType@12 referenced in function "void __cdecl useAPO(void)" (?useAPO@@YAXXZ)
The doc (again) says that you need to link to streambase.lib. If you aren't doing that, you should either change your project settings to link to it, or do it from your code:
#pragma comment(lib, "streambase.lib")

Yes, the MSDN doc says the last parameter is BOOL. And when I googled, I found three different prototypes.

I think it would be wise to go with what MSDN says.

...and streambase.lib you have to build. It's in the sample code and has build configurations for debug and release.

Don't have to build it. It comes with Mobile SDK 5.0
But event that doesn't match with the prototype.

I gave you a link to the documentation, and a hint, in my first reply. Did you check that you have included the correct .lib file in your project settings?

Yes, gone through it. But I already had visited them. After having googled, I posted the question here.
Anyway, thanks for your efforts.

Wow, but this is hard work.
Please post the exact code that causes you a problem along with any and all error messages as they appear on your screen. Only then can we begin to make a guess at your problem and its resolution. Before doing this make sure that you are using the proper format of any function calls, including the correct parameters, according to both the MSDN documentation (see link I provided earlier) and the actual header files in the version of the SDK that you are using. Ensure that you have included all the correct libraries in your project properties, again in line with the MSDN documentation.
Please do not waste your or our time with one liners like the above which serve absolutely no purpose.

When I modify these function calls to

it gives linker error as :
error LNK2019: unresolved external symbol _CreateAudioMediaType@12 referenced in function "void __cdecl useAPO(void)" (?useAPO@@YAXXZ)
This is what all I have in my code. I hope now this will help.
Thanks in advance.

Well that's quite clear, your function call does not match the function prototype in the package header file. As far as I am able to ascertain the correct definition is as described in this page[^] in MSDN.
Malli_S wrote: error LNK2019: unresolved external symbol _CreateAudioMediaType@12 referenced in function "void __cdecl useAPO(void)" (?useAPO@@YAXXZ)
Again this message is quite clear; the function you are attempting to call exists in an external library that has not been included in your project. Unfortunately the documentation for the CreateAudioMediaType() function does not indicate which library you need to include in your project. You could try checking the header file to see if it gives any information there. Unfortunately these functions appear to be part of the Windows Driver Kit, and I do not have a copy so am unable to offer any further suggestions.
You may like to recheck the documentation you are working from, or try posting on one of the Microsoft technical forums.

several sockets (multiple threading) on server-side share same public resource, such as user-array, for deleting, adding users etc.
sometimes, server crashes.
reason of server's crashing can't be debugged properly, but, from debug hints, I guess the reason is that when a socket is doing something on user-array but another socket start adding or deleting users on same array.
If this is real reason, how to avoid it? lock user-array? or other ways?
Thanks for comments.
