  1. To date I have only ever read this value and never tried to write to it. That said, this seems to work for toggling the setting on or off using Vectorscript:

     

    SetPref(544, NOT GetPref(544));

     

    Perhaps someone else with Python knowledge can spot something in your script.


  2. While is seems logical to try and emulate how you work with the mouse to select objects then edit them in some way, if you want to get into scripting then you'll find it much easier to work with handles. And the single most useful call for this is ForEachObject(), because it uses criteria to choose what gets processed. This can be object type, class, layer, colour, selection state, etc. Using FEO would look something like this:

     

    Procedure T;
    VAR
        grNewLen : REAL;

     

    Procedure DoIt(h1 : HANDLE);
    VAR
        rCenterX, rCenterY : REAL;
        rScaleFactor : REAL;
        rExistLen : REAL;
    BEGIN
        HCenter(h1, rCenterX, rCenterY);
        rExistLen := HLength(h1);
        rScaleFactor := (rExistLen + grNewLen) / rExistLen;
        HScale2D(h1, rCenterX, rCenterY, rScaleFactor, rScaleFactor, False);
    END;

     

    BEGIN { main }
        grNewLen := RealDialog('New Length?', '2');
        IF NOT DidCancel THEN ForEachObject(DoIt, (T = Line));
        Redraw;
    END;
    Run(T);


  3. Pat is right. Scaling the line using HScale2D is the way to go and it is easy enough:

     

    Procedure T;
    VAR
        h1 : HANDLE;
        rCenterX, rCenterY : REAL;
        rScaleFactor : REAL;
        rExistLen, rNewLen : REAL;
    BEGIN
        h1 := FSActLayer;
        HCenter(h1, rCenterX, rCenterY);
        rExistLen := HLength(h1);
        rNewLen := RealDialog('New Length?', Concat(rExistLen));
        rScaleFactor := rNewLen / rExistLen;
        HScale2D(h1, rCenterX, rCenterY, rScaleFactor, rScaleFactor, False);
        Redraw;
    END;
    Run(T);

     


  4. Yes, in an old PIO. It still works in 2020. Here is the code:

     

    Function GetColourIndex(CurrentIndex : INTEGER) : INTEGER;
    VAR
        DialogID, DlogResult : INTEGER;

        Function Define_Dialog: INTEGER;
        VAR
            dialogID : INTEGER;
        BEGIN
            dialogID := CreateLayout('Choose Colour', False, 'OK', 'Cancel');
            CreateGroupBox(dialogID, 4, '', False);
            CreateControl(dialogID, 5, 2,'',0);
            SetFirstLayoutItem(dialogID, 4);
            SetBelowItem(dialogID, 4, 5, 5, 0);
            Define_Dialog := dialogID;
        END;

        Procedure Drive_Dialog(VAR item:LONGINT; data:LONGINT);
        VAR
            red, green, blue : LONGINT;
        BEGIN
            CASE item OF
                SetupDialogC: BEGIN
                    ColorIndexToRGB(CurrentIndex, red, green, blue);
                    SetColorButton(DialogID, 5, red, green, blue);
                END;
                1: BEGIN
                    GetColorButton(DialogID, 5, red, green, blue);
                    RGBToColorIndex(red, green, blue, GetColourIndex);
                END;
                2: GetColourIndex := CurrentIndex;
            END;
        END;

    BEGIN
        DialogID := Define_Dialog;
        IF VerifyLayout(DialogID) THEN DlogResult := RunLayoutDialog(DialogID, Drive_Dialog);
    END;


  5. There is no official way to do it, however if you used CreateImageControl2() to insert the image as the first item in the dialog, you could probably then use SetBelowItem() with a large negative Y value to place the next item over the image and subsequent items below that. You will need to create a VWR file to store the image, which is simply a zip file of the image or images (without a parent folder), which you then just change the file suffix from .zip to .vwr.  If your zip/vwr file was called MyImages.vwr, and the image in there was called image1.png (use png images), then the call to place the image would be something like this:

     

    CreateImageControl2        (Dialog1, ItemID, 500, 400, 'MyImages/image1.png');

     

    The VWR file lives in the Plug-ins folder and 500/400 is the pixel size you want the image to appear in the dialog. Just make sure to preserve the image proportions. For example, this would work if the actual image was 1000 x 800 pixels, or 1500 x 1200, etc.


  6. I guess the first question is why does your PIO need to reset when the zoom level changes? Generally this should not be necessary. Ignoring that for the moment, if this were possible it could only work in an event enabled PIO using SetObjPropVS(). I don't have the full list at hand, but this is the function that allows PIOs to reset if there are layer scale or layer elevation changes, for example.


  7. This works for me:

     

    Procedure T;
    VAR
        BeamHandle : HANDLE;
    BEGIN
        BeamHandle:=CreateCustomObjectN('Wide Flange - 3D',0,0,0,FALSE);
        SetRField(BeamHandle,'Wide Flange - 3D','__series_2', 'AISC (Metric)');
        SetRField(BeamHandle,'Wide Flange - 3D','__size_2', 'W200 x 22.3');
        SetRField(BeamHandle,'Wide Flange - 3D','Length', '3000mm');
        SetRField(BeamHandle,'Wide Flange - 3D','__current_series', '2');
        SetRField(BeamHandle,'Wide Flange - 3D','__current_size_2', 'W200 x 22.3');
        Set3DRot(BeamHandle,0,45,0,0,0);
        ResetObject(BeamHandle);
    END;
    Run(T);

  8. Untested, but something like this should work...

     

    Procedure CheckSymbolExists;

    VAR

        gsSymNameCurrent : STRING;

     

    Function DoIt(h1 : HANDLE) : BOOLEAN;
    VAR
        sSymNameExist : STRING;
    BEGIN
        IF (h1 <> Nil) & (GetType(h1) = 16) THEN BEGIN
            sSymNameExist := GetSDName(h1);
            IF sSymNameExist = gsSymNameCurrent THEN SysBeep;
        END;
    END;

     

    BEGIN

        gsSymNameCurrent := StrDialog('Symbol name to search for:', '');
        ForEachObjectInList(DoIt, 0, 2, FSymDef);
    END;
    Run(CheckSymbolExists);

  9. It sometimes behaves like this Pat but I just tolerate the quirkiness and restart VW, Edit/Exit the WS Editor, etc. until it works. Typical of VS though. You steam along making great progress then something like this of another odd result stops you in your tracks. 


  10. Draw a rectangle on any sheet layer, that is just a bit bigger than the page size. Give it a unique name like 'Custom-Select-Rect'. Run the script below and substitute your PIO name for My PIO Name

     

    ForEachObject(SetSelect, ((LOC='Custom-Select-Rect') & (PON='My PIO Name')));

     

    This will select the objects on ALL sheet layers.
