Features
- Small footprint assemblies provide simple deployment as well as a
rich design-time experience.
Pocket Chart FX for .NET provides a design-time experience assembly compiled
against the .NET Framework that integrates seamlessly in Visual Studio .NET,
allowing you to setup chart attributes and properties easily. This
consistency ensures that there are no features in the design time version of
the control that will not be available in the run-time version limited to
work in the .NET Compact Framework and both assemblies adhere to the “small
is good” principle for mobile applications.
- Getting Help & Sample Code: The Chart FX Resource Center not
only provides specific samples for Pocket Chart FX for .NET but has been
also provisioned with the .NET Compact Framework emulators so you can
see each sample running in a virtual Pocket PC environment. To activate,
simply select the Smart Devices radio button at the top of the Resource
Center. The picture to the left depicts a live Pocket Chart FX for .NET
sample in the Resource Center.
- Additionally the Chart FX Resource Center features an API Section
where all Chart FX methods and properties can be accessed. Please be
aware that those objects, properties and methods supported in the .NET
Compact Framework will be accompanied by the “Supported by the Pocket
Chart FX for .NET”.
- Adherence to .NET Compact Framework design guidelines (runs 100%
natively in Pocket PCs).
As a GDI+ intensive component, Chart FX has been developed with coding
practices that can help improve draw speeds when using Graphics draw calls.
This is particularly important when considering applications in a mobile
platform where memory, CPU speed, and other resources are at a premium.
Considering that a PocketPC screen resolution is 240x320, we made sure chart
elements that usually take a lot screen space were removed from the default
chart settings and that charts accommodate and display well in a “portrait”
rather than a “l(fā)andscape” orientation; even the Chart FX default color
palette has been changed to improve end users ability to read charts in
small Pocket PC screens.
- Support for other mobile related technologies and tools like SQL
Server CE and Pocket Access.
SQL Server CE extends Microsoft SQL Server to Microsoft Windows CE-based
mobile devices, while providing developers with a consistent programming
model for rapid application development. Chart FX can read from native
SqlCEConnections and SqlCEDataAdapters for easy chart population. The
following C# code demonstrates how easy it is to populate a chart from SQL
Server CE data source.
SqlCeConnection myConn = new SqlCeConnection(@"Data Source = \Test.sdf");
myConn.Open();
SqlCeCommand myCommand = new SqlCeCommand(sSql, myConn);
SqlCeDataAdapter sqlCeAdapter = new SqlCeDataAdapter(myCommand);
DataSet dsChart = new DataSet();
sqlCeAdapter.Fill(dsChart);
Chart1.DataSource = dsChart.Tables[0];
- Free for development purposes to existing Chart FX for .NET or Chart
FX Developer Studio users.
If you are an existing Chart FX for .NET or Chart FX Developer Studio owner
please visit our support site or contact our sales department to obtain your
free copy of Pocket Chart FX for .NET. Runtime fees may apply. For

產(chǎn)品特性:
- 小范圍組裝特性提供簡單部署功能和豐富的設計體驗
.NET版本的袖珍圖表控件FX(Pocket Chart FX for
.NET)提供了設計組裝體驗,允許在.NET開發(fā)框架下編譯,并且可以與Visual Studio
.NET開發(fā)框架無縫集成;同時允許你輕松方便地設置圖表的屬性。它所具有的一致性可以保證:沒有任何功能在設計時有效而在運行時卻無效,而且不僅僅局限在.NET緊縮版框架中;兩種框架下面的組裝都堅持為移動應用程序考慮設計的“越小越好”的原則。
- 獲取幫助和示例代碼:
圖表控件FX資源中心不僅提供了為.NET版本的袖珍圖表控件FX所提供的具體示例代碼,而且還提供了.NET緊縮版框架仿真程序,你可以在虛擬的袖珍電腦環(huán)境下看見每一個示例代碼的運行情況。如果想激活運行某個示例代碼,只要簡單在資源中心的頂端選擇“Smart
Device”單選按鈕即可。資源中心左邊的圖片將會描述活生生的代碼運行情況。
圖表控件FX資源中心另外一大特色就是提供了API(應用程序接口)區(qū)域,從中可以訪問到所有的圖表控件FX的方法和屬性。要提醒的是,那些.NET緊縮版框架支持的對象,屬性和方法將會有“Supported
by the Pocket Chart FX for .NET”伴隨說明。
- 堅持.NET緊縮版框架設計指導原則(100%代碼在袖珍電腦本機運行)
作為一個圖形設備接口加強的控件,圖標控件FX在其開發(fā)過程中,當涉及到繪圖功能時,是通過能夠改善繪圖速度的編碼來實現(xiàn)的。這一點在開發(fā)移動平臺的應用程序時非常重要,因為移動平臺在內(nèi)存,CPU速度以及其他資源都是非常寶貴的。假設袖珍電腦的屏幕分辨率是240×320,我們必須確保:占據(jù)屏幕空間的圖表元素從默認的圖表設置中去除;同時圖表以肖像描繪的方式而不是風景拍攝的方式適應并且顯示出來;甚至調(diào)整圖表FX的默認調(diào)色板來改善終端用戶在小小的袖珍電腦屏幕上觀看圖表的效果。
- 支持其他的移動相關技術和工具(SQL Server CE and Pocket Access)
SQL Server CE將Microsoft SQL Server擴展到基于Microsoft Windows
CE平臺的移動設備上,同時給程序開發(fā)人員提供了連續(xù)的快速應用程序編程模型。圖表FX可以通過讀取本地的SqlCEConnections和SqlCEDataAdapters來輕松地繪制圖表。下面的C#代碼展示了從SQL
Server CE 數(shù)據(jù)源繪制圖表是多么方便簡單。
SqlCeConnection myConn = new SqlCeConnection(@"Data Source =
\Test.sdf");
myConn.Open();
SqlCeCommand myCommand = new SqlCeCommand(sSql, myConn);
SqlCeDataAdapter sqlCeAdapter = new SqlCeDataAdapter(myCommand);
DataSet dsChart = new DataSet();
sqlCeAdapter.Fill(dsChart);
Chart1.DataSource = dsChart.Tables[0];
- 對“.NET版本圖表FX”或者“.NET版本圖表FX開發(fā)者工作室”用戶,免費提供進行程序開發(fā)
如果你是一位“.NET版本圖表FX”或者“.NET版本圖表FX開發(fā)者工作室”所有者,請訪問我們的技術支持網(wǎng)址或者聯(lián)系我們的銷售部門獲取這些產(chǎn)品的免費拷
貝。可能需要支付運行費用。
