About code. Mostly on C++
The Chromium Embedded Framework (CEF for short) is an open source framework for embedding Chromium-based browsers in other applications. The base implementation is targeting C/C++ applications but ports for other languages exist (these include Java, C#, Delphi, Python). The nightly builds (for various systems and platforms) of CEF are available for download at https://cefbuilds.com/. These … Read more
Let’s say you have this VC++ project (or maybe more) targeting a 64-bit platform (x64 or IA64). You have the sources, everything is set. You build the solution and your project is skipped. You try again, maybe do a rebuild. The project is still skipped. You check the solution’s configuration manager, and the project is … Read more
I recently ran across a bug with an application ported to the x64 platform. After debugging the application the error turned to be due to integrals layout and casting. I think this is a typical example worth mentioning. It starts with this definition: #define COMBO_VALUE -99 which is used for a combo box with SetItemData: … Read more
If you include in a VC++ project <mapidefs.h> and <sqltypes.h> and build for the x64 platform you get a redefinition error. #include <Windows.h> #include <MAPIDefS.h> #include <sqltypes.h> int _tmain(int argc, _TCHAR* argv[]) { return 0; } 1>C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\sqltypes.h(283) : error C2371: ‘BOOKMARK’ : redefinition; different basic types 1> C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\MAPIDefS.h(1142) : see declaration … Read more
It is possible to register both 32-bit and 64-bit versions of the same COM server on 64-bit machine. This leads to several questions such as how are they registered and which one of the two is used. I will try to answer them below. But first, let’s start with an example. Example Let’s say we … Read more
I’m using Red Gate’s .NET Reflector for decompiling .NET assemblies. It’s a great tool but it lacks, at least in the free version I’m using, information about the platform architecture of an assembly. Sometimes I want to know whether an assembly was built for Any CPU, x86 or x64. The tool that help you find … Read more
I’m working on a project to port a 32-bit application for the x64 platform. The first errors that came up when building for x64 were related to inline ASM code, which is no longer supported in VC++ for x64. VC++ has an inline assembler built within the compiler, so you could write assembly code directly … Read more
If you want to port an existing 32-bit application for the x64 platform (especially since 32-bit processors will soon be history), or if you want to target x64 for a new application, the first step in building for x64 is setting up your solution. In this post I will explain what are the steps in … Read more
