.NET

[#1]

I am using Visual.net 2008 with autocad.net API, autocad2010, windows 7 home

right now, i want to start autocad.exe, and draw some lines in it, by using C# WindowsFormsApplication, not  C# Class Library

still i cannot start autocad.exe

I hope to open cad by autocad.net API, not ObjectARX or others

I am a new one,  please HELP ME

thanks very very much !

[#2]

There is no exe autocad, you mean acad.exe?

You cant program in autocad through windows forms with just opening acad.exe with out ObjectARX

[#3]

If you want to don't add any reference to acad's libraries

in this case just one way to do it is using late-binding to AutoCAD

There is a ton of code to do this work

[#4]

Here are 2 files were written on vb.net

See if this will be working fror you

[#5]

Thanks very much ! really appreciate your great help ~

actually i work it out by using C# library

[#6]

Create Wndws Forms Application project

Name it AcadTestExe

Add form Form1 to project

Drop on form OpenFileDialog, texbox and button

Keep default names for all controls

Add class ReflectionCommands.cs

Copy all codes accodingy to classes, then hit F5

Dear Hallex, you are genius!!!

I tried your codes, and it works very well~

Thank for your help, It's really great~

althought I cannot figured out how you fix it without adding any CAD liraries or dll

I am a new one in cad developping , these days I kept searching for any useful book or documents

still there is no result

Can you give me some advice for learning cad with C# ? Is there any useful documents for me ?

PS: I can draw circle by your  incredible codes, Could you please tell me how to draw a ARC ?

[#8]

C'mon

This is very simple code

Glad you like it

This project does not require any

CAD library

I tested it on A2009-2010 Win7

Will be back

dear Hallex:

   I use your code to draw some lines in cad,

  It is ok in WIN7 64bit + AUTOCAD2008 and WinXP + AUTOCAD2004

 but errors happened in WinXP + AUTOCAD2008

 my code is :

for (int k = 1; k < iHH.OutHHXY.Row - 1; k++)   
{
pt2[0] = iHH.OutHHXY[k, 0];
pt2[1] = iHH.OutHHXY[k, 1];
drawLineInObject(oSpace, pt1[0], pt1[1], pt2[0], pt2[1], "0");
pt1[0] = pt2[0];
pt1[1] = pt2[1];
}

The error happened in these lines:

object oLine = oBlock.GetType().InvokeMember("AddLine", BindingFlags.InvokeMethod, null, oBlock, pts);
oLine.GetType().InvokeMember("Layer", BindingFlags.SetProperty, null, oLine, new object[] { layer });
oLine.GetType().InvokeMember("Update", BindingFlags.InvokeMethod, null, oLine, null);

BUT , if I debug the loops one by one, It runs well. I am so confused~

please help me ~~

Thanks very much !!!
