希望,别做,才200分,为什么做?害人吗?
不过这样也行,我给你做,给我2000元吧,放点血,让你知道一下不读书的痛,而且我还会教你好多知识
你得先补基础。
最好去学校，找计算机系的学生，抄下专业专业课程和对应的课本（说不定顺便能讨些旧课本），卖齐这些课本（一般学校里面就有书店）慢慢学。
（以下课程不全）
至少需要读一遍的：计算机导论、程序设计基础、软件工程、编译原理
重点学习的：算法与数据结构、面向对象程序设计
还有VB.Net需要一定的基础，建议先从 C++ 或 VB（版本6.0）入门
textbox同步显示，只要将数据库表的某列数据绑定这个文本框就可以实现，其他控件也是一样的。至于打印你用水晶报表就行了，挺简单的

这只是添加记录的代码，对数据库的其它操作都是大同小异！自己好好琢磨把！
随手做了个打地鼠，代码拿去吧。
下图是10x10超大窗体“打地鼠”
直接新建个窗体，覆盖全部代码，不需要拖控件，全部动态创建了。
参数都在前面几行，可以随便改。
格子宽和高是70，间距20，因此横格子和竖格子不要超过10，不然窗体会扩张到非常大的程度。
调整时钟的Interval可决定地鼠的出现频率，你可以修改变化概率 = 15这句话改变出现几率。
