Hi, I've compiled the following snippet of code in VC++ 2005/2008: unsigned long ul = ...; signed long l = ...; l = ul; and was expecting to see a compiler warning (Warning Level set to 4), but none was generated. Am I missing something obvious here? Thanks ...

Hi all! I have a dynamic library (plugin) that uses another dynamic library (dependency). I use the dependency in two ways: a. by instantiating object from classes defined in the dependency b. by inheriting from classes defined in the dependency When doing a., there are no linking errors. But when doing b., I have a linking error stati...
When doing C# with VS2008, there is a file property "Copy to output directory". This property seems to be missing in VC++. What is the simplest way to approximate the same effect? I've been told that it should be done with custom build rules. Is this really the simplest way, and if it is, how should the custom build rule be implemented?...
Classic memcpy gotcha with C arrays as function arguments. As pointed out below, I have an error in my code but the erroneous code worked in a local context! I just encountered this weird behaviour in a porting job, where I'm emulating the Macintosh Picture opcode playback using objects. My DrawString object was drawing garbage on playb...
Hi, I would like to know if there are any ways to programmatically detect or monitor the file or folder being copied either by copy command(like on command prompt-- copy a b) or by using drag/drop(ctrl+c and ctr+v). It would be helpful if you could give some pointers( preferably some APIs in vc++) thanks and regards Dinakara K ...
When compiling these two files I am getting numerous errors. Please help me out. stchart.cpp # include "peg.hpp" # include "stchart.hpp" # include "stchart_res.hpp" external PegResourceTable stchart_ResourceTable; PEGINT gChartData [] = (100, 100, 100, 100, 100, 100, 125, 150, 175, 200, 150, 100, 50, 100...

Say I have a single project, with files A.cpp, B.cpp, C.ppp and matching header files (and that's it). The C++ files include system headers or headers from other modules. I want to compile them to a library with command line actions (e.g., using Make), using 'cl', with the precompiled headers feature. What are the steps I should do? Wh...
Hi, I'm wondering if there is a way to get better information about the location of an error in msvc (2005)? Exemple, when inheriting from boost::noncopyable in my class I get a C2248 error saying something like: error C2248: 'boost::noncopyable_::noncopyable::noncopyable' : cannot access private member declared in class 'boost::nonc...
Hello all. I searched around for the answers to these questions, but I have had little luck. So, I thought I would post them here to get some clarification. If this is a duplicate, please let me know, and I will close this. Okay, with that said, I would like to begin learning C++. I come from a C# background and I have a great respe...
Using http://support.microsoft.com/kb/240184 I'm able to open SAM, SOFTWARE, SYSTEM reg hives, but I do not know the next step to get them copied in a different backup folder? I get Access Denied when I try to use BackupRead API. Any help is much appreciated! ...
I have a very simple (currently just a main.cpp) CMake C++ project that I'm trying to build on both Mac OS X and Windows. It depends on libgsasl, which I have compiled as a static library on both platforms. Mac OS X has no problems building, and Windows doesn't complain during the build either and produces an EXE. When I try to run the ...
I rewrote a number-crunching two pages of code from C# to unmanaged C++ in my project, which with full optimizations gave a 3x speedup. I want to keep optimizing that code, but now my profiler of choice, dotTrace, can't do it, because it only looks at managed code. How do I profile the P/Invoked C++ module when it's running in the C# ap...
This is part of a series of at least two closely related, but distinct questions. I hope I'm doing the right thing by asking them separately. I'm trying to get my Visual C++ 2008 app to work without the C Runtime Library. It's a Win32 GUI app without MFC or other fancy stuff, just plain Windows API. So I set Project Properties -> Confi...

I have a 3rd party ActiveX control I want to render within other presentation technologies (Direct3D and WPF). To do this, I need the ActiveX to render to a system memory bitmap instead of the screen. I know there is a way to do this, but not sure where to start. I'm not afraid of doing any native method hooking, but I'm not sure wher...

The problem is that I'm currently using libcurl to communicate with amazon s3 for various operations, creating buckets, uploading, deleting and downloading objects. The problem is with the download function, I have set a callback function to wr...
