How to open DWG file in Autocad 2009 in C# ?

[Anonymous]

Hello,

I'm developping a dll for Autocad 2009.

I would like to know, how to open a DWG file ?

I tried :
Database db = new Database();
db.ReadDwgFile(file.Path, FileOpenMode.OpenForReadAndAllShare, true, "");
---> does nothing

Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(file.Path);
--> Error concerning Execution Context.

Thank you

Here's how you would do it in VB - I'll leave it to
you to convert.

You can't open a drawing file from a command handler unless
you specify CommandFlags.Session in the CommandMethod
attribute.

What works fine just the way you posted? Opening the document?

Duh!

Merely opening the document is not the problem. It never was. That isn't
what doesn't work.

Activating the opened document in order to use it to do anything that
requires the document to be active, is the problem..... stupid.

And no, doing that does not work without the CommandFlags.Session attribute
on the calling code.

Once again, we get to see the 'true you'.

First of all, thank you everyone.

Yes Kerry Brown, when i say that I want to open a file, I want it to be visible, and ready to be modified.

****
1 : I tried Joe Sutphin's solution.

I just had to convert the "Import" line into a "using" one 🙂

I get the same error just like I said :
Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(file.Path);
--> Error in french "Contexte d'excecution Incorrect"
--> Must be quit the same in english : "Excecution Context Incorrect" ?

****
2 : I tried Kerry Brown's solution

If I copy/paste your code to my main class (defined by the "[assembly: CommandClass(typeof(MyClass))]") , it works.

Tony Tanzillo is right, CommandFlags.Session attribute has to be mentionned.

But this solution doesn't really solve my problem.

****
My main class (defined by the "[assembly: CommandClass(typeof(MyClass))]"), just enables a custom Ribbon and defines which action has to be called on each button's click.

I have a class that manages some local files. It presentes these files in a listview, and when the user double click on the item, I would like to get the filepath and send it to a method that only does "opening file".
I aldready get the filePath and send it to the method.

For my test, i copied/pasted your code Kenny. (because I works in the main class)

I tried :
-- adding the CommandFlags above the method
-- putting this method as a public static one in the main class
---> I keep having the "Execution Context Error"

[Anonymous]

Yes, you do need the CommandFlags.Session attribute if the call to Open() is
made in the command method. But, I'm not clear on where your call to Open()
is coming from.

Is it coming from a function with the CommandMethod attribute, or from a
double-click handler of a form containing a ListView ? If the latter, is
the form being shown modally or modelessly?

The easiest way to get help on this, is to try to reproduce the error in a
sample project with the minimum code required to cause it to happen, and
post the project here.

I attached a zip contening 4 files (3 classes) :
--- Class RibbonActions
- RessourceDictionary.xaml : defines the GUI
- RibbonActions.cs : defines the behavior
--- Class Acad
Class that defines the assembly
--- Class FileManager
Class that defines a "file browser" (listView) and the behavior on a double click (Open the file)
The Browser is shown as modal :
{code}acadApp.ShowModalWindow(FilesManager); {code}
********
When I put the open file in the createRibbon() of the Acad class ((and add the commandFlags)) , it works
When I put the open file in the OpenFile(String filePath) of the FileManager class (( even with flags )), it doen't works (( Execution Context Incorrect ))

I hope it would help me being clear 🙂

[Anonymous]

The reason you're having this problem is because WPF executes
control code and events in a non-AutoCAD thread, which means
that you can't do very much with the AutoCAD API from a handler
of a WPF UI element.

One way to deal with it is to define a standard AutoCAD command
(which can also have the CommandFlags.Session flag) that calls
the Open() method, and then invoke the command using the
DocumentCollection's SendStringToExecute() method from the
event handler of your ListBox.

Another way to do it, is to call the DocumentCollection's
ExecuteInApplicationContext() method, and pass it the method
that contains the call to Open(), but for that to work, you must
close your Window right after calling ExecuteInApplicationContext,
because the callback will not run until that happens.

@apt42 :
I tried your solution.
Nothing happens. No error, but the drawing doesn't appear.

@Tony Tanzillo :
I tried the SendStringToExecute solution.
I think this solution best suits my application behavior (as I may have to open a file, from elsewhere in the application (( without the listview )) )
It works.

I just have a last question 🙂
When I use the SendStringToExecute("testOPEN", false, false, true);
The command is writen, but the editor is waiting me to press enter.
If I put the last parameter to false, the command isn't written anymore, but, How can I automatically press enter ? ( without doing it with my finger 🙂 )

Thank you all again for your help.

SendStringToExecute("TESTOPEN\n", ...)

You have to include a newline at the end of each input.
