来自主题: Database版 - Anybody familiar with VB ADO database
I wrote a simple VB program to work on a database. It uses ADO fuctions.
everything works fine. However, when i try to package it(using visual
studio package wizard) and install it on a clean pc (with no VB installed),
it complains about "ADO can not find provider"
What should I do?

Maybe u can try some stupid easy way,
using access , save the whole article in memo,
using VB to construct the searching fuction.
If it is just keyword search, u don't need to use SQL or other

There are several buttons in one page. It always calls the fuction no matter
clicking any button. Inside this function, how can we know which button is
clicked? In other word, how can we get value "b1" or "b2"?
The buttons in the HTML are defined like these.

来自主题: Java版 - Java IDE 选择?
Eclipse is free and has a huge user base, however Eclipse does not have a good
JSP plug in. Don't think it's a problem. Lot of developers prefer to code JSP
without using fancy IDE support.
IntelliJ is the most powerful java IDE I have ever used. The refactor fuction
is awesome. It is not free though.
So for your case, go for Eclipse.

Even many terms are vague in cs.
But these two are not vague at all when we talk about language. actually
they are one of the criteria to distinguish a type strong langauge and a
dynamic language.
aspectj by nature is just another layer of compilation. actually no aop has
ever brought dynamic variable and dynamic functions to the table.
dynamic variable and fuctions are very useful when you do not know what and
how many things you want your object to carry at compilation time.

I need to pass a cell matrix with variable size (m X n) to a own defined VBA

Range.Value2 to store the data into an assigned array variable successfully.
However, it requires the cells contain no formula. If the data in the cells

1。确定C++头文件中extern "C"声明的函数原型与C中的一致,包括参数类型在C中和C+
+中是否完全一致
2。确定这个C fuction的代码文件是用C编译器编译的,并且object文件添加到了C++工
程的连接库中
3。确定你的C++工程中其它obj中没有与这个C function同名的导出函数符号
这种问题你调试跟到c function里看一看就清楚了

the return value can be const or non-const. If the value is used as the

object. "Thinking in C++" says the temporary object is automatically const.
As a const, only the const member function can be used. However, my test

大概知道hash, hashtable的概念,主要是为了快速的lookup。
可是如果面试的时候被问到hash, hashtable,通常他们要考核的是什么?是要实现一个
好的hash fuction呢?还是要实现一个hashtable的class?
平时自己写代码的时候如果要用到一个hashtable,是不是可以用C++ STL tr1/

看了下面的链接,说是C++新的标准定义了四类hashtable,分别叫 unordered_set,
