推荐答案

yourDate.ToString("dddd")将日期返回为星期日，星期一...

yourDate.ToString("dddd") returns the day as Sunday, Monday...

使用此代码

如果Asc(e.KeyChar)= 13那么

将dim dt设置为新日期
dt ="26-12-2011"
将a变暗为整数
a = dt.dayofweek()
暗淡的str作为字符串
如果a = 1则
str ="Monday"
elseif a = 2则
str =星期二"
最多
elseif a = 7则
str ="sunday"
如果
结束

msgbox str


如果

use this code

If Asc(e.KeyChar) = 13 Then

dim dt as new Date
dt="26-12-2011"
dim a as integer
a=dt.dayofweek()
dim str as string
if a=1 then
str="Monday"
elseif a=2 then
str="Tuesday"
upto
elseif a=7 then
str="sunday"
end if


msgbox str


end if

你好，
我编写了简单的Windows窗体应用程序，
它由一个包含两个带有两列的DataGridView1控件的窗体组成，
当您在第一列的单元格中输入日期并按Enter时 同一行的第二列的单元格的值变为
根据输入的日期是星期几，
然后焦点将移至下一行第一列中的单元格.
我使用过:
DataGridViewCellEndEdit
当前单元格的编辑模式结束时发生的事件
再按Enter键，或在DataGridView控件中单击其他单元格.

Program.cs的代码

Hello,
I wrote simple Windows form application,
which consists of one Form containing DataGridView1 control with two columns,
when you enter date into cell in the first column and press enter the
value of the cell in the seckond column of the same row becomes the
day of the week based on the entered date,
and the focus moves to cell in the first column of the next row.
I have used the:
DataGridViewCellEndEdit
event that occurs when edit mode for the current cell ends
afther you press enter, or click on other cell in DataGridView control.
