Hi All, This is two questions in one but hopefully trivial to a C++ developer. How can I seralize an object so that I can write it to disk and retrieve it later in C++ or if this is the wrong keyword how can I write an object as a binary stream and recreate it later? Can I use inheritance to make a hierarchy of classes serializable? w...
It has methods like CRichEditCtrl::Copy(), CRichEditCtrl::Paste() which you can call, but I can't spot any messages the control is sent by Windows telling it to perform a paste operation. Does anyone know if such a thing exists? Or does CRichEditCtrl do something lower-level like monitoring WM_CHAR events? If so can I reuse any internal ...
i would like to know the function which returns the drive where the windows has been installed. for example if we run a program with following code in windows which is installed in "C:\" temp_char = getWindowsInstalledDrive(); should return "C:\". please point me to that function if you know. it should be a C/C++ function.

I have a simple class in C++ that has an integer and a vtable: class Something { virtual void sampleVirtualMethod(); int someInteger; }; If you look at the object layout for MSVC (using the /d1reportSingleClassLayout) you get: class Something size(8): +--- 0 | {vfptr} 4 | someInteger +--- W...
We layout dialogs using the resource editor. So say I have a RichEditCtrl called IDC_RICH. And I want to link it to an instance of a custom class CMyRichEditCtrl : CRichEditCtrl, without losing the ability to set properties on it in resource editor. What's the right way? You can certainly get some functionality by creating a DDX-linked ...

I am compiling 2 C++ projects in a buildbot, on each commit. Both are around 1000 files, one is 100 kloc, the other 170 kloc. Compilation times are very different from gcc (4.4) to Visual C++ (2008). Visual C++ compilations for one project take in the 20 minutes. They cannot take advantage of the multiple cores because a project depend ...

Hi, I found a very useful answer on how to create templated graphs using boost::graph under http://stackoverflow.com/questions/671714/modifying-vertex-properties-in-a-boostgraph/950173#950173 For me, this is very convenient as long as I do all the work on the graph in the Graph-class itself. However, it might be necessary to access in...
