Problem with PaletteSet location in Autocad

Anonymous — Fri, 25 Sep 2009 08:41:56 GMT

I'm having problem with chosing PalleteSetSet location in Autocad. No matter what I do, it is always docked on left side of Autocad window. My code is something like this:

PaletteSet ps;
ps = new PaletteSet("blabla", new Guid(System.Guid.NewGuid().ToString("B")));
ps.Style = PaletteSetStyles.NameEditable | PaletteSetStyles.ShowPropertiesMenu |
PaletteSetStyles.ShowAutoHideButton | PaletteSetStyles.ShowCloseButton;
ps.MinimumSize = new System.Drawing.Size(Width,Height);
ps.Size = new System.Drawing.Size(.Width,Height);
ps.DockEnabled = Autodesk.AutoCAD.Windows.DockSides.None;
ps.Add("blabla", new Palette());
ps.Visible = true;

Am I missing something? Edited by: JernejC on Sep 25, 2009 8:42 AM

Because you use "new Guid()" each time the PaletteSet is created. AutoCAD
persists PaletteSet's location using the GUID assigned to the PaletteSet as
identifier. You should get a fixed Guid value for your PaletteSet.

Which "new Guid()" is a problem?
1.) System.Guid.NewGuid().ToString("B") or
2.) new PaletteSet("blabla", new Guid(...))

I tried setting fixed Guid in first case but there are still no changes. In second case I don't know if there is any other way...

You need to use the same constant string when
you create the GUID:

{code}

Guid guid = new Guid(""255AA27F-A408-48d5-AA06-F311F3027A9D");

PaletteSet ps = new PaletteSet( "commandname", guid );

You can generate the string for the GUID from Visual Studio's GUIDGEN
tool, which is available from the Tools menu (Tools->Create GUID).

The important thing is that the GUID string must be constant and unique
for each paletteset, and should never change.

Sorry if this post is unreadable, I can assume no responsibility for the
gross incompetence that underlies Autodesk's online discussion group
software.

Hi,

I have created my GUID, and I'm trying to compile my code.
But always is the same error message:

Error 1 The type 'System.Windows.Interop.IWin32Window' is defined in an assembly that is not referenced. You must add a reference to assembly 'PresentationCore, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. C:\C#_Projects\test8\PreviewBox\PreviewBox\Class1.cs 30 20 PreviewBox

I have MVS2010 and AutoCAD2013.

Net framework 4.0.

What I should to do?

regards

Hi,

the message shows you:

have you done that?

Hmm...

no, I did not...

after the addition, works 🙂

I had to also add "static" in this line:

static Guid guid = new Guid("2919D05C-3A64-4098-B465-FCE445CBD1C7");
PaletteSet myPal = new PaletteSet("commandname", guid);

I test this example:

code:

thank you alfred.

Hmm...

this code is correctly compiled, but if I want to add DWG file, AutoCAD generates an error.
What is wrong?

Hi,

what I see when I open your project (have not started it at all):

you have set the property "local copy" for the references to "yes" ==> that should be "no"
how do you debug your project? When going to project-properties you have not set the "external program to start" to your ACAD.EXE or to the ACCORECONSOLE.EXE.

Interesting would be to see what message you get? Upload a screenshot from this message.

Where is this position?

OK.

I've added acad.exe.

After Debug (F5), AutoCAD2013 run and show me the error message:

Application does not support just-in-time (JIT)
debugging. See the end of this message for details.

I load my DLL (netload) and write PREV.

I write LDPRV, and error.

OK. I have found this "local copy".
I changed to "False".

Now, F5 (Debbug) doesn't generate an error, but still is when I write LDPRV.

Hi,

>> Now, F5 (Debbug) doesn't generate an error, but still is when I write LDPRV.

Ok, then next step is to tell the debugger to stop on all errors. Do that in Visual-Studio ==> pull-down-menu "debug" ==> item "exceptions" (hope that the translation from my German version is ok for that words) and within this dialog check "Common Language Runtime Exceptions".

Now exceptions raised during code will break the debugger and show you the position where the exception occured.

It's done.

I have found description this exception:

Do you have any idea what now?

Hi,

myPreviewBox is never set to an object (never instanciated) as this.Preview is never started.

Hmm...

in an example was:

/// <summary>
/// Instance of the Preview box
/// </summary>
PreviewBox myPreviewBox;

I have changed to:

PreviewBox myPreviewBox = new PreviewBox();

and now, the error is here:

maybe this example is incorrect and I never won't run this project?...

Hi,

does that happen with all drawings? Have you set your AutoCAD to "not save the thumbnails"?

The error seems to raise when the line above does not return a valid object (variable preview). So either there is no image in the file or the function does not return a bitmap.

(have not tried your code, so that's just guessing)

When I comment this line:

//grab the thumbnail bitmap and get rid of the white background
System.Drawing.Bitmap preview = dbb.ThumbnailBitmap;
//preview.MakeTransparent(System.Drawing.Color.White);

program run propertly, but view nothing in "My Palette"...

I added Alert in this place:

Autodesk.AutoCAD.ApplicationServices.Application.ShowAlertDialog("\nAlert " + fn.StringResult);
//use the loaded dwg file to update the preview box
myPreviewBox.load_file_preview(fn.StringResult);

and show me path to my DWG file - is correct, eg. "c:\Blocks\My_blok.dwg".

"does that happen with all drawings?" - Yes.

Have you set your AutoCAD to "not save the thumbnails"? - where can I set this?

Command _OPTIONS ==> tab "Open and Save" ==> button "Thumbnail Preview Settings"
