AutoCAD界面移植到VB.net应用程序窗体中
最近因为需要将AutoCAD界面移植到VB.net应用程序窗体中，琢磨、搜索了很久，终于搞清楚，贴出来。。。
1.首先涉及两个按钮，第一个是启动CAD进程，第二个是打开图形界面
2.第一个按钮的进程启动事件：
Private Sub txcl_qdcad_ItemClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraBars.ItemClickEventArgs) Handles txcl_qdcad.ItemClick
Dim runThread As Thread
runThread = New Thread(AddressOf qidongcad)
If txcl_qdcad.Caption = "启动AutoCad" Then
ztl_text.Caption = "温馨提示：若长时间无法启动，请线手动打开AutoCAD后重新启动..."
ztl_text.Refresh()
txcl_qdcad.Caption = "中止AutoCad"
runThread.Start()
ElseIf txcl_qdcad.Caption = "中止AutoCad" Then
txcl_qdcad.Caption = "启动AutoCad"
runThread.Abort()
ztl_text.Caption = "中止AutoCad成功"
ztl_text.Refresh()
End If
End Sub
’----线程
Private Sub qidongcad()
'SplashScreenManager.ShowWaitForm()
'SplitContainerControl1.Visible = False
'ChartControl_gxzx.Visible = False
'Dim acadApp As Autodesk.AutoCAD.Interop.AcadApplication
Try
'-------------------------------------------------
'启动CAD
'－－－－－－－－－－－－－－－－－－－－－－－－－－－
Try
acadApp = GetObject(, "AutoCAD.Application")
acadApp.Visible = False
Catch ex As Exception
Try
acadApp = CreateObject("AutoCAD.Application")
Catch dd As Exception
'SplashScreenManager.CloseWaitForm()
MsgBox("无法启动AutoCAD！", vbYes, "标题")
End Try
End Try
txcl_gbtxjm.Enabled = True
txsc_txsc.Enabled = True
txcl_qdcad.Enabled = False
ztl_text.Caption = "启动AutoCad成功"
Catch ex As Exception
txcl_qdcad.Enabled = True
'SplashScreenManager.CloseWaitForm()
MsgBox("未知错误，请尝试再次启动！", vbYes, "标题")
Exit Sub
End Try
'AppActivate(acadApp.Caption) '切换到CAD的界面为主体
End Sub
3.界面开启事件
Private Sub txcl_gbtxjm_ItemClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraBars.ItemClickEventArgs) Handles txcl_gbtxjm.ItemClick
If txcl_gbtxjm.Caption = "打开图形界面" Then
SplashScreenManager.ShowWaitForm()
acadApp = GetObject(, "AutoCAD.Application")
lHwnd = GetParent(GetParent(acadApp.ActiveDocument.HWND)) '获得CAD窗体的句柄
If lHwnd = 0 Then Exit Sub
lState = acadApp.WindowState
acadApp.WindowState = 1 'AcWindowState.acMax '设置ACAD的窗口状态为默认，用于保存窗口位置。
'GetWindowRect(lHwnd, r) '保存窗体原来的位置及大小到变量r
'MsgBox(Me.Left & "," & Me.Right & "," & Me.Top & "," & Me.Bottom)
'SetParent(lHwnd, Me.Handle) '设置CAD窗体的父窗体为当前VB窗框
SetParent(lHwnd, SplitContainerControl1.Panel2.Handle)
'SetWindowPos(lHwnd, 0, 0, 150, Me.Width - 10, Me.Height - 157, 0) '设置CAD窗体的大小及位置
SetWindowPos(lHwnd, 0, 0, 0, SplitContainerControl1.Panel2.Width, SplitContainerControl1.Panel2.Height, 0)
SetIcon()
'隐藏CAD标题栏
L = GetWindowLong(lHwnd, GWL_STYLE)
L = L And Not (WS_CAPTION)
L = SetWindowLong(lHwnd, GWL_STYLE, L)
'隐藏工具栏
HideTool()
txcl_qdcad.Caption = "启动AutoCad"
txcl_gbtxjm.Caption = "关闭图形界面"
txcl_kqgbmlh.Enabled = True
txcl_biaozhu.Enabled = True
ztl_text.Caption = "打开图形界面成功"
SplashScreenManager.CloseWaitForm()
ElseIf txcl_gbtxjm.Caption = "关闭图形界面" Then
If MsgBox("确认关闭图形窗口界面？", vbYesNo, "标题") = vbYes Then
On Error Resume Next
acadApp.Visible = False
If lHwnd = 0 Then Exit Sub
SetParent(lHwnd, 0)
SetWindowPos(lHwnd, 0, r.Left, r.Top, r.Right - r.Left, r.Bottom - r.Top, 0)
acadApp.WindowState = 1 'AcWindowState.acMax
'恢复隐藏的CAD标题栏
L = GetWindowLong(lHwnd, GWL_STYLE)
L = L Or (WS_CAPTION)
L = SetWindowLong(lHwnd, GWL_STYLE, L)
'恢复工具栏
For Each Menugroup In acadApp.MenuGroups
For Each Toolbar In Menugroup.Toolbars
If Toolbar IsNot Nothing Then
For ii = 0 To CadToolsxh - 1
Dim dqstr() As String
dqstr = Split(CadTools(ii), ",")
If Toolbar.Name = dqstr(0) Then
If dqstr(1).ToUpper = "TRUE" Then
Toolbar.Visible = True
Else
Toolbar.Visible = False
End If
Exit For
End If
Next
End If
Next Toolbar
Next Menugroup
acadApp.Quit()
acadApp = Nothing
ChartControl_gxzx.Visible = True
txcl_gbtxjm.Caption = "打开图形界面"
ztl_text.Caption = "关闭图形界面成功"
txcl_gbtxjm.Enabled = False
txsc_txsc.Enabled = False
txcl_qdcad.Enabled = True
txcl_kqgbmlh.Enabled = False
txcl_biaozhu.Enabled = False
End If
End If
