Issues with using pipe ( | ) symbol in Evaluate method in lotusscript

When attempting to use @DBLookup in Evaluate using lotusscript the following attempt succeeded

Evaluate({ @DbLookup("";"";"vwDB";"userName"; 2 ) })

But, replacing the curly braces with the pipe symbol failed,
I mean the following,
Evaluate(| @DbLookup("";"";"vwDB";"userName"; 2 ) |)

I even tried introducing the document parameter,in the following fashion,
Evaluate(| @DbLookup("";"";"vwDB";"userName"; 2 ) |,contextDoc)

I tried this in 8.5.1 and I believe it must be the same with all the other versions as well.

Simple Javascript Tester

When ever I work with javascript, I often have to test small functions. When working on cumbersome tasks, testing for smaller functions becomes a pain.

So in order to test them I developed this small useful tool.

Just copy and paste the following code into your html page, and there you go you get the tool that will work,

<textarea style="height: 300px; width: 600px;" id="scriptContainer"></textarea>

<button type="button" onclick="eval(document.getElementById('scriptContainer').value)">Evaluate</button>

In Xpages Context, Create a Custom Control, go to the source code panel, delete all the code that you see there, and copy paste the following code into it.This will give you a simple client side javascript tester tool.

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="">

    <xp:inputTextarea id="scriptContainer" style="height:300.0px;width:600px"></xp:inputTextarea>
    <xp:button value="Evaluate" id="button1">
        <xp:eventHandler event="onclick" submit="false">

You can also test your javascript code here,

Hope this helps :)

Invoking Escape key using Lotusscript

There was one scenario that pushed me to explore for options through which I can control the keyboard using lotusscript. My thought was to invoke the Escape key using lotusscript.
Though this did not resolve my issue, still it was a new discovery on my path.

Put the following code on a button in a form, compose the same and click it.

Dim objShell
Set objShell = CreateObject("WScript.Shell")
objShell.SendKeys ("{ESC}")

You will see the current form getting closed. Yes this code actually simulates the Escape key press on the keyboard.Again I believe that this will only work in windows

Hope this helps :)

Getting Current Row Index in a Repeat Control

Create a Repeat control with a label inside it. For assistance regarding creating a repeat control take a look into the following post,

Select the Repeat Control, go to the properties pane and type in the value named "rowIndex" in the field that says "Index name:". The following figure is an illustration of the same

Now Select the Label inside the Repeat control, and compute its value as illustrated in the following figure,

Now save and preview the XPage. You shall see a screen that is similar to the following,

I have actually used the word "rowIndex" which I have keyed in as a value in the Index Field field (fig 1) as a variable and have assigned the same as the label value. Hence It gets updated for each and every row and this you see the result that has been produced , i.e the numbers 0 to 4

Creating Repeat Controls in XPages

Following is a simple illustration of how a repeat control works in XPages
1. Create a new XPage.

2. Open the Control Palette

3. Drag and Drop the control named Repeat Control on to the XPage

4. Now Drag and Drop a Label Control into the Repeat Control present in the XPage

At this point of time you will be seeing something similar to the following on your screen

5. Now select the repeat control, go to the properties panel and check the property named "Create Controls at Page Creation"

6. In the Iteration section select Javascript and put the value 5 as highlighted in the figure above.

7. Now save and preview the XPage.You will be able to see five labels being displayed on the Screen

Forall equivalent in Formula Language - @Transform

I felt amazed when I found the Forall (lotusscript) equivalent in Formula Language.

The command is @Transform. It has a typical syntax that it is difficult for beginners to understand.

The syntax for the command is as follows,

@Transform( list ; variableName ; formula )

The parameter named variableName is the culprit that works in a tricky way. In addition the name of the command itself is no where similar to Forall and hence is used less due to lack of a meaningful name, I suppose.

The following is a little illustration of how to use the function.Assume that the following code is in a button (ofcourse you can copy this into a button),


@Transform ( 


This will bring up three prompt with the texts - FirstValue, NextValue and LastValue in each of them respectively.

Here the key is understand how I used the iterator parameter myListValue. First I pass it as a string and there after I use it as if it is a normal variable.

The above mentioned code fragment is equivalent to the following in lotusscript.


dim myList as variant
Forall  myListValue in myList
   msgbox myListValue
End Forall


Hope this helps :)

A toggle display - Changing styles of a button control dynamically in XPages

In a normal HTML page changing the look and feel of a button dynamically is very easy. All have to do is write a few lines of Javascript. But the same will often let you down in XPages.

Yes I have tried this on a Button Control in an XPage. My requirement was to give it a look and feel which simulates a toggle like display for the button on the screen. The color of the button needs to toggle between green and blue gradients each time I click it. Normal client side javascript which i use to do in normal HTML Pages failed.

Even when stuffs worked fine, when a server level refresh happens, the change gets nullified. So I had to do the following to keep up with the task.

1. Create a Button control on the XPage
2. Code such a way that you associate a field control to its onclick event. That is when ever you click on the button, mark the field control with a flag.Let me Name the field as FlagField
3. Go to the Style tab of the button control in the properties pane.
4. click the little diamond against the style class name as illustrated in the following figure

5.This will open up the script editor. Put up the code as illustrated in the following figure.

6. Now write a style sheet with the following code,

    background-repeat: no-repeat;
    background-size: 100%;

    background-repeat: no-repeat;
    background-size: 100%;

and associate the same with the XPage.

7. This is it. Now you can preview your button and view the difference.
A sample illustration of the look feel is shown in the following figure
Hope this helps :)

Excel Manipulations with Java (POI 3.6)

This post consists of a code fragment that can be used to perform various operations like, creating excel files, updating them, copying images in the excel files and pushing them into an applet using Java.

My experiments in this post can be summarized into the following
  • createWorkBook()
  • readFromWorkBookDemo()
  • writeToWorkBookDemo()
  • getPictureData()

In order to work with these functions you may have to download the following jars, get them into the resources of your project and proceed with my code.
I have used the POI 3.6 API to accomplish the same .

Booking resources/rooms for a meeting

In order to book a resource or a room for a meeting, the place you may have to do the same is in the Resourcereservations.nsf database that shall exist in the domino directory of your organization's server.

Also making reservations here will ensure that it gets updated with all future meetings that u schedule, that is will say where the resource is booked or not automatically when some one else tries to book a meeting which includes the same

Creating links to databases which exists elsewhere, under domino directory

1. Open the domino admin client.
2. Right click on the folder under which you want to create the link. Click New and Click Link

3. This will bring up a pop as mentioned in the following screen shot  

4. I name my link as MyFirstDominoLevelLink and I am mapping the same to a folder path “F:\DB_OutOf_Data_Dir”. Also In the above screen shot note that there are no entries found in the highlighted section by the link name that I am about to create.

5. Clicking ok creates the link and is displayed as follows

   6. My external folder named “F:\DB_OutOf_Data_Dir” contains 3 databases as shown in the following screen shots

7. Now clicking on my link should show all these databases in my admin client and that was what I got

One of the typical usages of creating these links are, they come in handy when it comes to memory management and in cases mentioned in previous post

    Scheduling agents in local databases

    In order to run scheduled agents locally i.e. in local databases , you got to ensure that the highlighted property is enabled. Other wise it wont run, really.

    Also the database must be with in the data directory.

    If in case the database is not with in the data directory then, you got to create a link to the database under the data directory. To know more about creating the link go through the next post.

    Canvas - List of commands that a beginner needs to know


    Applying Styles for canvas

     <style type="text/css">
           canvas { border: 1px solid black; }


    var ctx =canvas.getContext("2d");
     ctx.fillStyle = "rgb(200,0,0)";
     ctx.fillRect (10, 10, 55, 50);
     ctx.fillStyle = "rgba(0, 0, 200, 0.5)";


    fillRect(x,y,width,height) : Draws a filled rectangle
    strokeRect(x,y,width,height) : Draws a rectangular outline
    clearRect(x,y,width,height) : Clears the specified area and makes it fully transparent

    rect(x, y, width, height)

    Besides the three methods we saw above which draw rectangular shapes directly to the canvas, we also have a method rect which adds a rectangular path to the path list.

    This method takes four arguments. The x and y  parameters define the coordinate of the top left corner of the new rectangular path. width and height define the width and the height of the rectangle.

    When this method is executed, the moveTo method is automatically called with the parameters (0,0) (i.e. it resets the starting point to its default location).

    Drawing paths


    One very useful function, which doesn't actually draw anything, but is part of the path list described above, is the moveTo function. You can probably best think of this as lifting a pen or pencil from one spot on a piece of paper and placing it on the next.

    moveTo(x, y)

    For drawing straight lines we use the lineTo method.

    lineTo(x, y)

    For drawing arcs or circles we use the arc method. The specification also describes the arcTo method, which is supported by Safari and Firefox, but wasn't implemented in the older Gecko browsers.
    arc(x, y, radius, startAngle, endAngle, anticlockwise)

    Bezier and quadratic curves

    The next type of paths available are Bézier curves, available in the cubic and quadratic varieties. These are generally used to draw complex organic shapes.

    quadraticCurveTo(cp1x, cp1y, x, y) // BROKEN in Firefox 1.5 (see work around below)
    bezierCurveTo(cp1x, cp1y, cp2x, cp2y, x, y)

    A quadratic Bézier curve has a start and an end point (blue dots) and just one control point (red dot) while a cubic Bézier curve uses two control points.


    drawImage(image, x, y)
    drawImage(image, x, y, width, height)
    drawImage(image, sx, sy, sWidth, sHeight, dx, dy, dWidth, dHeight)

    controlling Image Scaling Behavior : mozImageSmoothingEnabled


    fillStyle = color
    strokeStyle = color


    globalAlpha = transparency value

    Line styles

    lineWidth = value
    lineCap = type
    lineJoin = type

    globalCompositeOperation = type

    type is a string representing any one of twelve compositing operations. Each of the available types is described below.

    Note: In all of the examples below the blue square is drawn first and referred to as 'existing canvas content'. The red circle is drawn second and referred to as 'new shape'.

    source-over (default)
    This is the default setting and draws new shapes on top of the existing canvas content.


    New shapes are drawn behind the existing canvas content.


    The new shape is drawn only where both the new shape and the destination canvas overlap. Everything else is made transparent


    The existing canvas content is kept where both the new shape and existing canvas content overlap. Everything else is made transparent.


    The new shape is drawn where it doesn't overlap the existing canvas content.


    The existing content is kept where it doesn't overlap the new shape.


    The new shape is only drawn where it overlaps the existing canvas content.


    The existing canvas is only kept where it overlaps the new shape. The new shape is drawn behind the canvas content.


    Where both shapes overlap the color is determined by adding color values.


    Where both shapes overlap the color is determined by subtracting color values.


    Shapes are made transparent where both overlap and drawn normal everywhere else.


    Only draws the new shape and removes everything else.


    Note: Currently the copy and darker settings don't do anything in the Gecko 1.8 based browsers (Firefox 1.5 betas, etc).

    Ceil command simulation in Lotusscript

    Assume that you have a numeric expression "numExpr" on whichyou want to perform the Ceil operation.

    This can be achieved by using the following expression,


    In java Math.Ceil(9/5) will return 2.
    Fix(9/5)+1 will also return 2... thus Ceil command simulation in Lotusscript is achieved

    Hope this help :)

    Floor command simulation in Lotus script

    The command named Fix returns the Integer part of a fractional number.

    This is similar to the command named Floor in Java or Javascript

    For example ,  Msgbox Cstr(Fix(9/5)) will alert '1'

    Also a particular numerical expression can be expressed as ,

    Fix(numExpr) + fraction(numExpr) = numExpr.

    And this is always true.
    For More Info refer to the designer help
    Hope this helps :) Cheers

    Passing Values Through Scoped Variables

    This post may seem complex. But it is really simple. Just follow the first three steps blindly. Then you will get to know my point of simplicity.

    1.Create an XPage and go to the Source panel.
    2. Select all the xml code that you see there and replace the same with the following code,

    <?xml version="1.0" encoding="UTF-8"?>
    <xp:view xmlns:xp="">
    <xp:button value="Label" id="button1">
            <xp:eventHandler event="onclick" submit="true"
        <xp:label value="#{javascript:sessionScope.Label}" id="label1">

    3. Now go to the Design Panel of the XPage.

    4. There you go, you will see a Button and a Label as you see in the following screen shot,
    5. The button named label will have the following code in its onclick event,
    sessionScope.Label+="x", and the same is illustrated in the following figure

    6. The label needs to have a computed value with the following code in it.
    sessionScope.Label, and this is as illustrated in the following figure,
    7. Now preview the page on the browser or on a 8.5.1 client and click the button.

    8. You will see that the label get changed every time you click the button, and the same is illustrated in the following screen shot
    What really happens here is that the label has been mapped to a sessionScope variable.When ever you click the butto, it updates the same and hence the label also gets its value refreshed.

    Hope this helps :)
