[求助]如何保存缩略图？

gsteven

打开后关闭并保存

Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(operFilePath, false);

Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
                Database db = doc.Database;
                Editor ed = doc.Editor;

savepath = operFilePath;
                doc.CloseAndSave(savepath);

之后，发现如果原来图形有缩略图的，保存之后还会有缩略图，原来没有缩略图的，保存之后还是没有。但是原来没有缩略图的，我手工打开DWG，然后保存一下就有缩略图了。

请问如何把缩略图保存出来？

命令 ： BLOCKICON

没用啊

for (iDwg = 0; iDwg < dwgCount; iDwg++)
            {
                operFilePath = dwgFilesRoute[iDwg].ToString();//获得操作图形路径
                if (fileType=="DWG")
                {
                    Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(operFilePath, false);
                }
                else//DXF
                {
                    Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(operFilePath, true);
                }
               

                Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
                Database db = doc.Database;
                Editor ed = doc.Editor;
                //db.CloseInput(true);
                //DocumentLock lok = doc.LockDocument();

                //Utils.ZoomObjects(true);//范围缩放视图
                //curVtr = ed.GetCurrentView();
                //Point2d d2d = new Point2d(curVtr.Target.X, curVtr.Target.Y);
                //curVtr.CenterPoint = new Point2d(0, 0);
                //curVtr.Target = new Point3d(0, 0, 0);
                //curVtr.ViewDirection = new Vector3d(0, 0, 1);
                //curVtr.CenterPoint = d2d;

                //ed.SetCurrentView(curVtr);

                //lok.Dispose();
                doc.SendStringToExecute("BLOCKICON",true,false,false);

                //db.Save();
                labelExecuteCondition.Text = "正在范围缩放" + System.IO.Path.GetFileName(operFilePath) + "视图,请等待……";
                labelExecuteCondition.Visible = true;
                finish = (int)((Double)(iDwg + 1) / (Double)(dwgCount) * 100);
                progressBar1.Value = finish;
                progressBar1.Visible = true;
                this.Update();
                //savepath = System.IO.Path.GetDirectoryName(operFilePath) + System.IO.Path.GetFileNameWithoutExtension(operFilePath);
                //savepath = folderPath+System.IO.Path.GetFileNameWithoutExtension(operFilePath);
                //savepath = "D:\\杂记\\1";
                savepath = operFilePath;
                doc.CloseAndSave(savepath);
                //try
                //{
                //    doc.CloseAndSave(savepath);
                //}
                //catch (System.Exception eRR)
                //{
                //    doc.CloseAndSave(temppath);
                //    if (fso.FileExists(operFilePath))
                //    {
                //        fso.DeleteFile(operFilePath, true);
                //    }

                //    fso.MoveFile(temppath, operFilePath);
                //}

                //if(fileType=="DWG")
                //{
                //    doc.CloseAndSave(savepath);
                //}

                //if (fileType == "DXF")
                //{
                //    doc.CloseAndSave(temppath);
                //    if (fso.FileExists(operFilePath))
                //    {
                //        fso.DeleteFile(operFilePath, true);
                //    }

                //    fso.MoveFile(temppath, operFilePath);
                //}

            }

汗，搞错，blockicon是生成块图标的：）

不过缩略图为什么需要？

可以试下Wblock或直接调用Save命令

gsteven

算了，缩略图不要也罢

只是有个问题，就是比如点击一个按钮，但是按钮执行的是一个循环，循环体如果使用editor发送命令，无论什么命令，都不执行。

还有，如果不是循环，那么发送的命令会在这个按钮事件函数全部执行完毕之后，CAD开始执行发送的命令。不知道这是为什么。

[CommandMethod("MODFRM",CommandFlags.Session)]
        public void modify()
        {
           
           
            DwgFrame Fra = new DwgFrame();
            Autodesk.AutoCAD.ApplicationServices.Application.ShowModelessDialog(Fra);
        }

DwgFrame 是一个窗体，上面有按钮。不知道怎样才能让按钮事件中发送的命令立即执行，执行之后再回到按钮事件继续往下执行？

SendStringToExecute会产生延时，试下这个
