vs有sp1补丁，pda程序也是vs2010编写的，为什么打不开？

2个回答

pda程序是什么？windows ce的程序？不可能用2010写的，肯定是2008或者以前的版本，vs2010删除了对windows ce项目的支持。

Polly Nomials 程序怎么来写
Description The Avian Computation Mission of the International Ornithologists Union is dedicated to the study of intelligence in birds, and specifically the study of computational ability. One of the most promising projects so far is the "Polly Nomial" project on parrot intelligence, run by Dr. Albert B. Tross and his assistants, Clifford Swallow and Perry Keet. In the ACM, parrots are trained to carry out simple polynomial computations involving integers, variables, and simple arithmetic operators. When shown a formula consisting of a polynomial with non-negative integer coefficients and one variable x, each parrot uses a special beak-operated PDA, or "Parrot Digital Assistant," to tap out a sequence of operations for computing the polynomial. The PDA operates much like a calculator. It has keys marked with the following symbols: the digits from 0 through 9, the symbol 'x', and the operators '+','*', and '='. (The x key is internally associated with an integer constant by Al B. Tross for testing purposes, but the parrot sees only the 'x'.) For instance, if the parrot were presented with the polynomial x3 + x + 11 the parrot might tap the following sequence of symbols: x, *, x, *, x, +, x, +, 1, 1, = The PDA has no extra memory, so each * or + operation is applied to the previous contents of the display and whatever succeeding operand is entered. If the polynomial had been x3 + 2x2 + 11 then the parrot would not have been able to \save" the value of x3 while calculating the value of 2x2.Instead, a different order of operations would be needed, for instance: x, +, 2, *, x, *, x, +, 1, 1, = The cost of a calculation is the number of key presses. The cost of computing x3+x+11 in the example above is 11 (four presses of the x key, two presses of '*', two presses of '+', two presses of the digit '1',and the '=' key). It so happens that this is the minimal cost for this particular expression using the PDA. You are to write a program that finds the least costly way for a parrot to compute a number of polynomial expressions. Because parrots are, after all, just bird-brains, they are intimidated by polynomials whose high-order coefficient is any value except 1, so this condition is always imposed. Input Input consists of a sequence of lines, each containing a polynomial and an x value. Each polynomial anxn+an-1xn-1+...+a0 is represented by its degree followed by the non-negative coefficients an , ... , a0 of decreasing powers of x, where an is always 1. Degrees are between 1 and 100. The coefficients are followed on the same line by an integer value for the variable x, which is always either 1 or -1. The input is terminated by a single line containing the values 0 0. Output For each polynomial, print the polynomial number followed by the value of the polynomial at the given integer value x and the minimum cost of computing the polynomial; imitate the formatting in the sample output. Sample Input 3 1 0 1 11 1 3 1 0 2 11 -1 0 0 Sample Output Polynomial 1: 13 11 Polynomial 2: 8 11

PDA设备，自动扫描后，输入框获取不到值
PDA设备，自带扫条码。但是无法将值输入到Ifream中的输入框中，但是去掉Ifream后 可以正常使用。但是Ifream又是必须的，如何解决？急求

Android 手持PDA 如何让扫描到的数据，跟随光标，输入到任意EditText

C#PDA 与server端用什么进行通信比较好呀？

PDA有自带的硬键盘，当有多个EditText存在时候。我点击硬键盘的回车键，跳转到下一行，我要怎么让输入法不显示。只有去点击PDA的屏幕的时候才显示输入法。还有就是当我只存在一个EditText的时候，我要多次获取这个焦点，我要怎么控制输入法不弹出？麻烦讲的清楚点，网上都是隐藏输入法的代码，但是都是根据获取焦点后才隐藏，这导致了输入法先弹出来，再做隐藏，用户体验太差。

vs2008开发wince连接数据库打开conn。OPen（）时候抛出异常
``` public static string SqlStr = "server=.;database=PDA;uid=sa;pwd=sa123"; public static SqlConnection OpenDatabase() { SqlConnection conn = new SqlConnection(SqlStr); conn.Open(); return conn; } ``` 编译的时候错误如下 ![图片说明](https://img-ask.csdn.net/upload/201601/13/1452667708_100324.png) WorkStationsId会有影响吗，感觉很奇怪 ，不知道错在哪里了。
