Opening Document

Anonymous — Tue, 24 Jul 2007 20:50:36 GMT

I thought opening a list drawings from a user form was just matter of calling DocumentManager.Open method, but I can't make it work. Can someone please give a hand on how to do it properly. TIA

Here is how I do it.

(defun MyOpen (FileName ReadOnly / )

(vla-Open
(vla-get-Documents
(vlax-get-Acad-Object)
)
FileName
(if ReadOnly
:vlax-true
:vlax-false
)
)
)

Oops. Wrong forum, but is still the same.

DocumentManager.Open(< DrawingPath >, < ReadOnly >);

At least that is how I do it in my C# app, and it works. But you could also
leave out the readonly options.

DocumentManager.Open(< DrawingPath >);

Thank you Willey for replying but I still stuck on this issue. Here is the line of code I am having trouble with:
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(FilePath, False) FilePath is a valid IO file path, but I am getting this error msg "Invalid execution context" , I think it has something to do with the ApplicationExecutionContext, but I am not clear on how this works. I trying to open the drawings from a user form opened by the Application.ShowModalDialog method. Any help will be greatly appreciated.

That explains it: unlike the VB modal user form, when a modal form is open
in .NET API, you cannot use DocumentCollection object to open a drawing.

Workaround would be either open the drawing prior to the modal dialog's
openning, or open the dialog as modeless.

If your modal dialog is started from a command handler,
register the command with CommandFlags.Session, and
set your Form's Visible property to false before you call
Open(), and back to true after Open() returns.

Tony,

Question one what you said.

Can this method be used on any dialog box? I have routines where I use
dialog boxes, and the information is stored within them. Once the okay
button is pressed I close the dialog, and fill an array with the contents of
the dialog I want to store. Could I just turn the dialog invisible instead,
use the contents, then close the dialog? Is this a good way, or just a work
around?

Thanks in advance.

Sorry for the highjack.

Thank you Tony. Here is how I have made the command declaration:

Public Shared Sub UpdateBox()
Dim frm As System.Windows.Forms.Form

frm = New frmUpdateDwgs
Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(frm)

frm.Dispose()

End Sub

I still getting the same "Invalid execution context" error message. Could you explain what does hiding the form while opening the drawings do. Any suggestions?

Hi Tim.

As long as your code is running in the application
context (e.g., the IsApplicationContext property
of the DocumentManager is true), you should have
no problem.

If that's happening then rather than hiding
the form, in your command method, call
ShowModalDialog() inside of a loop, and each
time it returns DialogResult.Ok, open the
drawing files. When ShowModalDialog() returns
something other than DialogResult.Ok, exit
the loop.

Re: Opening Document

Tony, maybe I have not being able to explain the situation clearly. The "Invalid execution context" error occurs, when I try to iterate thru the list of drawings opening them. The form frmUpdateDwgs works fine. Once it is displayed the user can select drawings files from the system drives. The problem is, when I try to open each drawing (hiding the form here didn't do anything). In VBA this procedure works fine, but in .NET the Application/Document context restrictions make it difficult to make this code work. Unfortunately, I don't have much documentation and I haven't been able to find anything meaningful on the subject. I am starting to think that perhaps this won’t work. Your help is really appreciated.

Did you take this advice of Tony's:

register the command with CommandFlags.Session

Re: Opening Document

Anonymous — Wed, 25 Jul 2007 23:46:26 GMT

Simply add CommandFlags.Session does not work. I tested this code:

In command defining class:

[CommandMethod("MyOpen", CommandFlags.Session)]

public static void OpenFile()

{

using (dlgCmdTest dlg = new dlgCmdTest())

{

Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(dlg);

}

}

dlgCmdTest is a win form with a button on it. The Button_Click event handler
looks like:

private void button1_Click(object sender, EventArgs e)

{

string file = "E:\\Work\\Acad\\DataCadTest\\2007\\070202\\070202PC01R0.dwg";

this.Visible = false; //Or this.Hide(); The same effect

try

{

Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(file);

}

catch (Autodesk.AutoCAD.Runtime.Exception ex)

{

MessageBox.Show("Error: " + ex.Message); //I got error "eNoDocument".

}

this.Visible = true;

}

After start Acad, NETLOAD the dll, issue command "MYOPEN", the form shows.
Clicking the button, the MessageBox pops up.

Re: Opening Document

Did you see my last reply, and if so, did you try it?

What I said was to place a loop in your command
method function, and in the loop, show your dialog.
After the call to ShowModalDialog() returns, then
open the documents.

Here's the C# code:

public class MyForm : Form
{
// set this to true to terminate looping:

public bool exitloop = false;
}

public class MyCommandClass
{
[CommandMethod("MyCommand")]
public static void MyCommand()
{
MyForm form = new MyForm();
while( ! form.exitloop )
{
AcadApp.ShowModalDialog(form);
if( ! form.exitloop )
AcadApp.DocumentManager.Open(...);
}
}
}

Tony with all your respects, your suggestion doesn't work or I can't make it work. The process is started from the command declaration and once the form is shown its code takes focus, only to pass it back to the command sub when the form is closed. What I need is a way of making the DocumentManager.Open method work while the form is running. How or under which conditions does this method work? Is it possible at all to have a form running and call this method?

Re: Opening Document

Public Class frmUpdateDwg
Public Function GetDrawings()

Dim opnFiles As Autodesk.AutoCAD.Windows.OpenFileDialog

opnFiles.ShowDialog()

Return opnFiles.GetFilenames

End Function

Dim Lst() As String
Dim FilePath As String
Dim ListItem As ListViewItem

Lst = Me.GetDrawings()

If Not Lst Is Nothing Then

If Lst.Length > 0 Then

Me.ListView1.BeginUpdate()

For Each FilePath In Lst

If Me.ListView1.Items.ContainsKey(FilePath) = False Then

ListItem = Me.ListView1.Items.Add(FilePath, System.IO.Path.GetFileName(FilePath), 0)
ListItem.SubItems.Add(FilePath)

End If

Next
Me.ListView1.EndUpdate()
End If
End If
End Sub

Private Sub ButtonAddDrawings_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonAddDrawings.Click
Call Me.LoadDrawings()
End Sub

Private Sub ButtonUpdateDrawings_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonUpdateDrawings.Click
Dim ListItem As ListViewItem

If Me.ListView1.Items.Count > 0 Then
For Each ListItem In Me.ListView1.Items
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(ListItem.SubItems(1).Text, False)
Next
End If
End Sub

Private Sub ButtonExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonExit.Click

End Class

Hi Mikko,
I don't know if you have tried to run your code, I will say you did. If you don't get any "Invalid execution context" let me know which version of AutoCAD you are using and any particular settings in your project. I am doing almost the same thing in my code and I get the error message.

2008 and yes this does work for me. Nothing special, that is the whole of it.

one more thing is, I'm not using:
Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(frm)
instead I use:
