Parsing CArchive (MFC classes) files in Ruby

由 余生颓废 提交于 2019-12-24 23:12:10
问题 I have a legacy app that seems to be exporting/saving files with CArchive (legacy MFC application). We're currently refactoring the tool for the web. Is there a library I can look at in Ruby for parsing and loading these legacy files? What possible libraries could I look into? Problems with the file format according to XML serialization for MFC include: Non-robustness —your program will probably crash if you read an archive produced by another version of your program. This can be avoided by

How do I implement a legacy TCP/IP service in WCF and C#?

由 我们两清 提交于 2019-12-24 11:54:15
问题 I have a legacy TCP/IP service which listens for a message in a proprietary format on a socket. When the service receives the message, it processes it and replies with a message in a similar format, (classic request/reply situation). We cannot change the client calling the legacy service and we want to replace the legacy service with a new one hosted in IIS using WCF and C#. How do I implement this in WCF? Is it even possible to make WCF understand the proprietary message format? If not then

HttpServletRequest logout on old servlet-api-2.3.jar

由 非 Y 不嫁゛ 提交于 2019-12-24 11:44:25
问题 For legacy reasons we're using servlet-api-2.3.jar, in which HttpServletRequest not yet had the logout method. What do I do instead? We're also using an old version of Oracle's ATG, which contains a class called DynamoHttpServletRequest as well, but I don't know what to do with that either. What to try/read? 回答1: It depends on what the semantics of logging in are in your application. Typically, this should do it unless you're doing something exotic: request.getSession().invalidate(); I'm not

Rails 3 model mapping certain columns to different model attributes

由 久未见 提交于 2019-12-23 21:38:47
问题 I have the old legacy table called "DXFTACCTS", and I created Rails model "Account". class Account < ActiveRecord::Base set_table_name "DXFTACCTS" end The problem is that DXFTACCTS has fields like "XORFNAME" which I want to be "first_name" in the model, and so on. How do I "map" specific table columns to model attributes? Thanks! 回答1: You can use the method alias_attribute like this: class Account < ActiveRecord::Base set_table_name "DXFTACCTS" alias_attribute :first_name, :XORFNAME end alias

戴尔台式机安装win 7系统

使用相应品牌电脑进入BIOS的快捷键，进入BIOS设置 1、BIOS引导】： 传统的电脑通常都是使用BIOS引导，开机BIOS初始化，然后BIOS自检，再引导操作系统→进入系统，显示桌面。 （选择Setup是进入BIOS） 2、光盘启动： 在BIOS引导的情况下，通常使用安装光盘维护、安装操作性系统，只要找到CD-ROM（或者DVD，主板菜单不一样）使用上下键，选中此项，按回车键（Enter）予以确认，再按F10键，重启电脑，就能认光驱里面的安装光盘了。 3、u盘启动： 在BIOS引导下，u盘PE系统的操作和光驱引导设置方法类似，只要找到USB选项（有的主板是显示u盘的型号），设置为第一启动项即可，重启电脑就会读u盘PE系统了。 4、【UEFI引导】： UEFI引导的流程是开机初始化UEFI，然后，直接引导操作系统，进入系统。和传统的BIOS引导相比，UEFI引导少了一道BIOS自检的过程，所以开机就会更快一些，这也成为了电脑的新宠。 5、进入设置主界面，继续点击Boot（引导）菜单，Boot mode（引导模式）右边的就是当前的引导模式，这里默认的是UEFI引导。 6、选中该项回车，打开设置项之后，这里有两个选项：UEFI 和 Legacy（使用上下键选中），引导模式选择Legacy。 7、点击OK，确认修改为Legacy引导模式。 8、提示询问是否现在重启电脑？点击 yes

Can I throw C++ exceptions from legacy C callbacks?

由 橙三吉。 提交于 2019-12-23 07:39:03
问题 I have C++ code that uses some C libraries. The C libraries take C language callbacks. I wrote a callback in my C++ code and now I somehow need to report error from it (but it returns void). I wonder if I can throw an exception from a C callback that is used from C++ code? This is very difficult for me to understand. Thanks, Boda Cydo. 回答1: Yes, you should be able to do so. However, keep in mind it's entirely likely that the C library was not written to be exception safe, and as a result you

Why doesn't VFP .NET OLEdb provider work in 64 bit Windows?

问题 I wrote a windows service using VB that read some legacy data from Visual Foxpro Databases to be inserted in SQL 2005.

I'm getting a message the the VFP .NET OLEdb provider is not found. I researched and everything seems to point out that there is no solution. Any Help, please... 回答1: Have you tried changing the target CPU to x86 instead of

Breaking a local dependency to unit test a void method

由 让人想犯罪 __ 提交于 2019-12-21 20:55:46
问题 I am practicing with mockito, but I am a bit stuck on how to test a method that depends on a call to method in a local object. See the following example: public class Worker { public void work() { Vodka vodka = new Vodka(); vodka.drink(); } } This worker, instead of doing his job, he likes drinking. But I want to add a test to prove that he drinks while he works. But there is no way of doing so, because I must verify that the method drink() is called when the method work is called. I think

Is the .NET Framework usable on Win98?

由 岁酱吖の 提交于 2019-12-21 12:11:02
问题 I need to write a little tool for a customer to be run on Windows 98. Since this is a very small project I'd hope that I could avoid having to go native C++ and use C#. The .net Framework 2.0 download claims to support Windows 98. Are there any caveats or hitches to be aware of when installing or coding? 回答1: There are a few features that Win98 won't support such as form opacity and balloon tooltips. If you use any P/Invoke, you'll have to make sure to support ANSI versions of functions (use
