还是站在巨人肩上做学习再开发。
有两个Gantt组件都有for .Net的。
1) varChar xgantt3.1 for .Net
2) ILOG Gantt 3.0 for .Net
索性将这两个都破解了!
2006.2.9
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
varchar Gantt 3.1 activeX 组件破解，花了我一天的时间，先用Delphi7写一个实例，再用od跟踪，JMP了三次
就OK了！
2006.2.10
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
VS2005和Delphi 2006在我的本上躺着好久，差一点儿都想不起来了，一直在用Delphi7开发AutoCAD插件，没有时间来学他。
今天看来要用上他了，用Reflectorn打开ILOG License manager 程序,看到：

就想到在他基础上开发一个license generate，既可以管理license又可以当作license 生成器。
先到这儿，下次有时间再继续讲讲如何Crack ILOG Gantt for .Net.
