In the Access Project (that is, the. ADP file) linked to an SQL Server database, the access function that you frequently use is usually not supported. But most of the time, you can use a Transact-SQL (T-SQL) function supported by SQL Server. One exception is that access's null (null) functions NZ and isnull; they have similar functionality, but they are not supported by access and T-SQL. This article will discuss when and how to use these two function

should meet the following requirements:
1. the precondition is not stronger than the base class.
2. The subsequent conditions are not weaker than the base class.
In other words, when you call an object through a base class interface, you only know the base class prerequisites and subsequent conditions. Therefore, the inherited class does not require users to provide a stronger precondition than the base class method, that is, the inherited class method must accept any conditions (parameters) th
:
InfoTableAdapter adp = new InfoTableAdapter();
2. Create a memory table object
Mydb.InfoDataTable table = new Mydb.InfoDataTable();
3. query return
table = adp.GetData();
4. Modify
InfoTableAdapter adp = new InfoTableAdapter(); adp.UpdateBycode(name, sex, nation, birthday, code);
Example: display the memory dataset (Dataset) in the datagridview, add, delete, and modify the dataset, and then submit
In fact, if the paging does not require high performance, you can use

The principle is while (0 {If (! Container1.read ()){Return 0;}Startrecord --;}Int num1 = 0;If (0 {While (num1 {If (this. _ hasfillerrorhandler){Try{Mapping. loaddatarowwithclear ();Num1 ++;}Catch (exception exception1){If (! ADP. iscatchableexceptiontype (exception1 )){Throw;}

Browsers have always been the tools we use on our computers. If the browser is running too slow, you will be very unhappy. So in the use of IE browser is what we should pay attention to, in the following article tutorial share their own experience bar.
If you use IE browser, often used to watch TV dramas and so on, and hate advertising, you can change the Firefox browser. Then install a ADP plugin on the line.

In order to debug and run applications on real devices, the following steps are generally required:
If you are using an Android development phone (ADP), such as Nexus One or Nexus S, download Google's USB drive.
If you are using other Android devices, such as Sony, LG, HTC, then download the corresponding OEM USB driver.
