ask:

   If you want to initialize bhatch dialog boxes with specific values ​​or keep the previous value of the dialog box, how should we do?

answer:

    Please check the following code shows how to override the default bHatch command implementation and use of a specific value to call the dialog box.

void CommandLine_CommandExecute(string commandname, bool isDefaultImplemented, ref bool success)
{
      if (string.Compare(commandname, "bhatch", true) == 0)
      {
          vdDocument doc = vdFramedControl1.BaseControl.ActiveDocument;

          //Set some initial values for the dialog , This can be global to an application so these values can be changed. 
          //You can call the following dialog with a different constructor (with vdHatchproperties) in order to set these values in a global properties application dialog that you may have.
          vdHatchProperties SetBhatchInitialValues = new vdHatchProperties();
          SetBhatchInitialValues.FillMode = VectorDraw.Professional.Constants.VdConstFill.VdFillModeHatchBlock;
          SetBhatchInitialValues.FillColor.ColorIndex = 0;

          //Keep in a variable the current ActiveHatchProperties
          vdHatchProperties KeepActiveHatch = new vdHatchProperties();
          KeepActiveHatch.CopyFrom(doc.ActiveHatchProperties);

          //Set the ActiveHatchProperties to the above value
          doc.ActiveHatchProperties.CopyFrom(SetBhatchInitialValues);

          //Call the dialog.
          vdFigure ret = VectorDraw.Professional.Dialogs.frmGetHatchDialog.Show(null,doc, doc.ActionControl);

          //Return ActiveHatchProperties values as it was before the dialog.
          doc.ActiveHatchProperties.CopyFrom (KeepActiveHatch);
          success = true;
          return;
      }
}
