Visual Studio 2008 will be confused? 回答1: Visual Studio 2010 has support for multiple .config files. It is one feature of new web application packaging and deployment system. We can create now separate web.config files for each configuration we have for application. But for 2008 there are no support for multi config files, you can workaround this by adding two config files and rename them in build time

Domino Designer 8.5.3 then tells me to change the project's compliance level to 1.5 in a quick-fix action. If I do that, the project rebuilds and nothing changes. Nothing happens if I go to the project's Java Compiler settings to set it manually, or change it in the workspace settings either. How can I get rid of this error? 回答1: There is an annoying bug in Domino Designer. The "Compiler Compliance Level" in File / Preferences will always show 1.5

I then tried to install the above egit plugins and was able to install egit and jgit but was unable to install Maven SCM Handler for EGit. I tried updating grvia the m2e marketplace and got the following error: Cannot complete the install because of a conflicting

Big Endian and Little Endian support for byte ordering

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: We need to support 3 hardware platforms - Windows (little Endian) and Linux Embedded (big and little Endian). Our data stream is dependent on the machine it uses and the data needs to be broken into bit fields. I would like to write a single macro (if possible) to abstract away the detail. On Linux I can use bswap_16 / bswap_32 / bswap_64 for Little Endian conversions. However, I can't find this in my Visual C++ includes. Is there a generic built-in for both platforms (Windows and Linux)? If not, then what can I use in Visual C++ to do byte

Preprocessor macro in parent project for use in subproject

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I have an Xcode project, which has a subproject which is a static library. I've defined a preprocessor macro in the parent project (in Build Settings), and I want it to be recognized by the subproject at compile time (I have some #ifdef statements in the subproject). But the macro is always undefined in the subproject, no matter what I do. Is it possible to do what I want? 文章来源: Preprocessor macro in parent project for use in subproject
