今天是接触MOSS开发的第二天, 任务的难度开始增大. 项目需要添加若干List, 用于保存数据. 其中一个List包含一个颜色类型的自定义字段. 今天的任务就是用代码实现这个自定义字段.
正式的步骤和代码参考这里, 需要注意的几点如下:
1. 代码文件的项目需要签名, 注册到GAC中
2. acsx组件文件需要保存到模板目录中
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\CONTROLTEMPLATES
3. xml文件需要注意文件名称格式, 同样需要保存到对应的xml目录中
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\XML
注意: 正式使用自定义字段前需要重新启动iis: iisreset
还谈不上有什么心得, 只是今天初到新公司, 利用Visual Studio .net 2008做了几个小例子(Web Parts), 有点兴奋, 记录一下.
1. SayHello: 显示一行文本信息
2. Custom Property: 增加自定义属性
3. TextMessage: 两个Web Parts间的数据传递
public void EnumInstanceFromInt()
{
// The .NET Framework contains an Enum called DayOfWeek.
// Let’s generate some Enum instances from int values.
// Usually you wouldn’t cast an instance of an existing Enum to an int
// in order to create an Enum instance. :-) You would have the actual
// integer value, perhaps a value from a database where the int value of
// the enum was stored.
DayOfWeek wednesday =
(DayOfWeek)Enum.ToObject(typeof(DayOfWeek), (int)DayOfWeek.Wednesday);
DayOfWeek sunday =
(DayOfWeek)Enum.ToObject(typeof(DayOfWeek), (int)DayOfWeek.Sunday);
DayOfWeek tgif =
(DayOfWeek)Enum.ToObject(typeof(DayOfWeek), (int)DayOfWeek.Friday);
lblOutput.Text = wednesday.ToString()
+ “. Int value = ” + ((int)wednesday).ToString() + “\n”;
lblOutput.Text += sunday.ToString()
+ “. Int value = ” + ((int)sunday).ToString() + “\n”;
lblOutput.Text += tgif.ToString()
+ “. Int value = ” + ((int)tgif).ToString() + “\n”;
}
Result:
Wednesday. Int value = 3
Sunday. Int value = 0
Friday. Int value = 5
