$("input[type='checkbox']").attr("checked",true);
用js這樣就行了,如果用C#,參考如下:
foreach (Control item in this.Controls)
{
if (item is CheckBox)
{
CheckBox box = (CheckBox)item;
box.Checked = true;
}
}
VB.net中CheckListBox如何通過(guò)程序做選擇。
CheckedListBox1.CheckOnClick = True
指示復(fù)選項(xiàng)是否應(yīng)在首次單擊時(shí)更改狀態(tài)
CheckListBox.GetItemChecked
返回復(fù)選框是否被選中的真假項(xiàng)
要用代碼賦是否勾選某項(xiàng)的值應(yīng)該用setitemchecked
VB.Net讀取AutoCAD圖紙
如果可以的話請(qǐng)把分給我
以下是cad2007版的,引用autocad 2007 type library 和autocad/objectdbx common 17如果是04或者版本更低的只要引用autocad 2007 type library,代碼的話大同小異,思路是一樣的
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
On Error Resume Next
Dim acadapp As Autodesk.AutoCAD.Interop.AcadApplication
acadapp = GetObject(vbNullString, "autoCAD.application")
Dim acaddoc As Autodesk.AutoCAD.Interop.AcadDocument
acaddoc = acadapp.ActiveDocument
Dim Ms As Autodesk.AutoCAD.Interop.Common.AcadModelSpace
Ms = acaddoc.ModelSpace
Dim acadObjectI As Autodesk.AutoCAD.Interop.Common.AcadObject
Dim Linei As Autodesk.AutoCAD.Interop.Common.AcadLine
Dim Circlei As Autodesk.AutoCAD.Interop.Common.AcadCircle
Dim Polylinei As Autodesk.AutoCAD.Interop.Common.AcadPolyline
Dim pt As Autodesk.AutoCAD.Interop.Common.AcadPoint
For Each acadObjectI In Ms
Debug.Print(acadObjectI.ObjectName)
Select Case acadObjectI.ObjectName
Case "AcDbLine"
Linei = acadObjectI
Debug.Print("X =" Linei.StartPoint(0).ToString)
Debug.Print("Y =" Linei.StartPoint(1).ToString)
Case ""
Case ""
End Select
Next
End Sub
