Are you an ADO developer who needs to migrate your knowledge and code from a PC to a Pocket PC? I'll show you the similarities and differences between ADO and ADOCE through some code instances.
This article requires:
· Microsoft? eMbedded Visual Tools.
· Microsoft SQL Server Developer Edition.
· SQL Server Windows? CE Edition.
· Microsoft ADOCE (ActiveX?) Data Objects CE) 3.1 included with SQL Server W
Access the database using adoce in EVC
I just started to develop PPC applications. Considering that I am familiar with the c ++ language, I chose the evc4.0 + Pocket PC 2003 SDK development environment. I'm glad that many things are almost the same as VC ++ 6.0, and they get started quickly. However, we encountered difficulties in database de

Mobile Service System design Mobile database SQL Server CE
Because mobile service systems need to download maintenance orders to mobile devices and temporarily save maintenance orders on mobile devices, a database system is required on mobile devices. The Mobile database system we chose is SQL Server CE.
Microsoft SQL, Windows ce Edition (also known as SQL Server CE), is a small relational database used on mobile devices. The development

15. Is the update statement in adoce and pocket access not executable?
Adoce cannot directly execute the update statement, but adoce has the update method, which can be used for implementation.

through participation in Microsoft activities. MEDC 2005 participants received development CDs for VS. NET 2005 and Windows Mobile 5 SDK.
7. Q: How is the managed code execution efficiency? Compared with the code written in Visual C.
A: The execution efficiency of managed code is certainly not as high as that of local code, but managed code also has some benefits that cannot be replaced.
8. Q: Can I use Visual Studio. NET 2003 to develop applications that can run on Windows Mobile 2005?
A: Firs
Database is a flat structure and cannot define the relationship between attribute databases. Using Microsoft ActiveX Data Object for Windows CE (ADOCE) technology, you can access the Attribute Database in capacity, or even use SQL statements to query information.

Ado
In Windows Mobile and wince platforms, Microsoft does not support ADO. But there is a community implementation that can refer to a set of
First, let's look at the simplest:
For database programming in WinCE, you can use the simple adoce + pocket access method.
The access file format in the pocket PC is. cdb. You can use either of the following methods to generate a data file in the. cdb format:
1. Program Implementation: you can write your own program implementation (this article will be published after a search on the web page ~)
2. Use ActiveSync for conversion: Create a database

The. dat file defines the Directory and file structure of the Windows CE image NK. Nib blacklist. Note that winodws ce does not support drive letters like Windows 9x/20
supported; Visual Basic. Net supports XML and XML Web Services for local machines.
Improved data model: Ado. Net far exceeds adoce; it is still the best data model
Safer and more reliable execution: EVB is a scripting language, and Visual Basic. Net is a hosted code.

At the same time, there are a variety of resources (from porting experiments to technical articles) to help developers with this transition. An example is an ove
