I have two questions about pdf reports with Genexus, I hope somebody can help me:
1) how can I wrap the text value of a variable in PDF reports?
2) I saw that textblock controls are the only ones that have the wrap property, so, in this case, how can I assign a value dinamically?
Best regards,
Leonardo
In reports, to wrap text in variables (typically Varchar or LongVarchar fields) you can use the GXMLines and GXGetMLi functions.
Example:
&nlin = GXMLines(&LongText,40)
For &i = 1 to &nlin
&txtLine = GXGetMLi(&LongText, &i, 40)
Print txtLines // (printblock that prints &txtLine)
EndFor

Kendo UI 2015.2.805 Kendo UI Editor for Jacascript
I want to extend the kendo ui editor by adding a custom tool that will convert a user selected block that spans two or more paragraphs into block of single spaced text. This can be done by locating all interior p tags and converting them into br tags, taking care not to change the first or last tag.
My problem is working with the range object.
Getting the range is easy:
var range = editor.getRange();
The range object has a start and end container, and a start and end offset (within that container). I can access the text (without markup)
console.log(range.toString());
Oddly, other examples I have seen, including working examples, show that
console.log(range);
will dump the text, however that does not work in my project, I just get the word 'Range', which is the type of the object. This concerns me.
However, all I really need however is a start and end offset in the editor's markup (editor.value()) then I can locate and change the p's to br's.
I've read the telerik documentation and the referenced quirksmode site's explanation of html ranges, and while informative nothing shows how to locate the range withing the text (which seems pretty basic to me).
I suspect I'm overlooking something simple.
Given a range object how can I locate the start and end offset within the editor's content?
EDIT: After additional research it appears much more complex than I anticipated. It seems I must deal with the range and/or selection objects rather than directly with the editor content. Smarter minds than I came up with the range object for reasons I cannot fathom.
Here is what I have so far:
var range = letterEditor.editor.getRange();
var divSelection;
divSelection = range.cloneRange();
//cloning may be needless extra work...
//here manipulate the divSelection to how I want it.
//divSeletion is a range, not sure how to manipulate it
var sel = letterEditor.editor.getSelection()
sel.removeAllRanges();
sel.addRange(divSelection);
EDIT 2:
Based on Tim Down's Solution I came up with this simple test:
var html;
var sel = letterEditor.editor.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
html = html.replace("</p><p>", "<br/>")
var range = letterEditor.editor.getRange();
range.deleteContents();
var div = document.createElement("div");
div.innerHTML = html;
var frag = document.createDocumentFragment(), child;
while ((child = div.firstChild)) {
frag.appendChild(child);
}
range.insertNode(frag);
The first part, getting the html selection works fine, the second part also works however the editor inserts tags around all lines so the result is incorrect; extra lines including fragments of the selection.
The editor supports a view html popup which shows the editor content as html and it allows for editing the html. If I change the targeted p tags to br's I get the desired result. (The editor does support br as a default line feed vs p, but I want p's most of the time). That I can edit the html with the html viewer tool lets me know this is possible, I just need identify the selection start and end in the editor content, then a simple textual replacement via regex on the editor value would do the trick.
Edit 3:
Poking around kendo.all.max.js I discovered that pressing shift+enter creates a br instead of a p tag for the line feed. I was going to extend it to do just that as a workaround for the single-space tool. I would still like a solution to this if anyone knows, but for now I will instruct users to shift-enter for single spaced blocks of text.
This will accomplish it. Uses Tim Down's code to get html. RegEx could probably be made more efficient. 'Trick' is using split = false in insertHtml.
var sel = letterEditor.editor.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
var block = container.innerHTML;
var rgx = new RegExp(/<br class="k-br">/gi);
block = block.replace(rgx, "");
rgx = new RegExp(/<\/p><p>/gi);
block = block.replace(rgx, "<br/>");
rgx = new RegExp(/<\/p>|<p>/gi);
block = block.replace(rgx, "");
letterEditor.editor.exec("insertHtml", { html: block, split: false });
}
I want to use JXA to automate some updating of Numbers spreadsheets. For example, copying a range of cells from one spreadsheet to another one with a different structure.
At this point, I'm just testing a simple program to set or read the value of a cell and I can't get this to work.
When I try to set a value I get "Error -1700: Can't convert types." and when I try to read a value I get back a [object ObjectSpecifier] rather than a text or number value.
Here's an example of the code:
Numbers = Application('Numbers')
Numbers.activate()
delay(1)
doc = Numbers.open(Path('/Users/username/Desktop/Test.numbers'))
currentSheet = doc.Sheets[0]
currentTable = currentSheet.Tables[0]
console.log(currentTable['name'])
console.log(currentTable.cell[1][1])
currentTable.cell[1][1].set(77)
When I run this, I get and output of [object ObjectSpecifier] for the two console.logs and then an error -1700: Can't convert types when it tries to set a cell.
I've tried several other variations of accessing or setting properties but can't get it to work.
Thanks in advance,
Dave
Here is a script that sets and gets a cell's value and then sets a different cell's value in the same table:
// Open Numbers document (no activate or delay is needed)
var Numbers = Application("Numbers")
var path = Path("/path/to/spreadsheet.numbers")
var doc = Numbers.open(path)
// Access the first table of the first sheet of the document
// Note:
// .sheets and .tables (lowercase plural) are used when accessing elements
// .Sheet and .Table (capitalized singular) are used when creating new elements
var sheet = doc.sheets[0]
var table = sheet.tables[0]
// Access the cell named "A1"
var cell = table.cells["A1"]
// Set the cell's value
cell.value = 20
// Get the cell's value
var cellValue = cell.value()
// Set that value in a different cell
table.cells["B2"].value = cellValue
Check out the Numbers scripting dictionary (with JavaScript selected as the language) to see classes and their properties and elements. The elements section will show you the names of elements (e.g. the Document class contains sheets, the Sheet class contains tables, and so on). To open the scripting dictionary, in Script Editor's menu bar, choose Window > Library, and then select Numbers in the library window.
In regards to the logging you were seeing - I recommend using a function similar to this:
function prettyLog(object) {
console.log(Automation.getDisplayString(object))
}
Automation.getDisplayString gives you a "pretty print" version of any object you pass to it. You can then use that for better diagnostic logging.
I'm using the following command to print a justified text:
^FB1800,3,0,J^FT100,200^A0B,26,26^FH\^FDLONG TEXT TO BE PRINTED, WHICH DOESNT FIT IN ONLY 3 LINES...^FS
The command ^FB1800,3,0,J prints a field block in a width of 1800 dots, maximum 3 lines, justified.
The problem is that if the text exceeds the maximum number of lines, it overwrites the last line! :( That of course makes the text of the last line unreadable.
How can I avoid that? Does anybody know if is there a way to cut the exceeding text?
The documentation says exactly that this happens:
Text exceeding the maximum number of lines overwrites the last line. Changing the font size automatically increases or decreases the size of the block.
For reference: I'm using printer Zebra 220Xi4.
Any help would be appreciated. Thank you!
Take a look at the ^TB command. It is preferred over the ^FB command and truncates if the text exceeds the size defined in the TB params
I had just about the same problem, what fixed it in my case - although not the most elegant way - is to specify a higher number of maximum lines, and then formatting it in a way that only the first 3 are in the visible area.
In your case it would be for example ^FB1800,7,0,J instead of ^FB1800,3,0,J
This at least fixed it for me right away, because I print this text at the bottom of the label. If you need to have it somewhere in the middle or top, there might be some tricks with putting a (white) box on top of the overflow-area, since the Zebra printers seem to render before printing. Hope it helps.
Depending on the higher-level programming language you're using (assuming that you are), you could accomplish the same thing (truncate the text to be printed to a specified number of characters) with code like this (C# shown here):
public void PrintLabel(string price, string description, string barcode)
{
const int MAX_CAPS_DESC_LEN = 21;
const int MAX_LOWERCASE_DESC_LEN = 32;
try
{
bool descAllUpper = HHSUtils.IsAllUpper(description);
if (descAllUpper)
{
if (description.Length > MAX_CAPS_DESC_LEN)
{
description = description.Substring(0, MAX_CAPS_DESC_LEN);
}
}
else // not all upper
{
if (description.Length > MAX_LOWERCASE_DESC_LEN)
{
description = description.Substring(0, MAX_LOWERCASE_DESC_LEN);
}
}
. . .
This is what I'm using; is there any reason to prefer the "raw" ^TB command over this?
sorry for my question and for the long explanation following here, probably there's a simple solution for someone who is experienced in Cocoa and Objective-C, but I'm just starting few weeks ago and I can't figure out how to get this thing working, Grrrrrrr!!
OK, let's put it like this, in my window I have the following:
2 TextField(NSTextField) called:
blockOffText
blockOnText
1 Label(NSTextField) called:
flightTimeText
1 button(NSButton) called:
updateButton
What I want to do is all about time calculation I guess, get the "start-time" in one TextField and the "end-time" in the other.
One is supposed to be the "takeoff-time" and the other the "landing-time" or for example the "duty-startTime" and "duty-endTime"...it's the same!
Then I want to calculate the "flight-time" or "duty-time" and show it in the Label.
At the end I will also need to store the value or the time in a database as an integer, the value should be represented by all minutes corresponding to each time, but the database part is not a problem at the moment.
Maybe I can write the number in the TextField without the format but just the number and get the time show-up formatted in some way?
I would like to write for example "1245" and "1525" without having the needs to put the ":" between the hours and minutes, then can I get the value formatted "12:45" "15:25" in the TextField in some way? Maybe after pressing the button?
Ok, that is a second problem anyway, my real problem is I need to get the value I wrote in the TextField ("1245" and "1525") to be assigned to some variables in the program that I called "BlockOff" and "BlockOn".
I need to transform them in an integer that represent the minutes corresponding to their value..example:
The 1245 will become 765 minutes...(12 times 60 + 45)
and 1525 will become 925 minutes...(15 times 60 + 25)
HOW CAN I DO THIS?
In this way I can use the minutes to calculate the difference to get the flight time or even add flight time to other flight time.
At the moment my program works a little bit differently... like this:
If I directly assign the value to the two variables:
int blockOff = 765;
int blockOn = 925;
then I can calculate and show in the two TextField the takeOff and landing time formatted like I want: "12:45" "15:25"...I use other 2 variables to do so:
int oreBlkOff, minBlkOff = 0;
minBlkOff = blockOff % 60;
oreBlkOff = (blockOff - minBlkOff) / 60;
Then I can show the value in the TextField:
[blockOffText setStringValue:[NSString stringWithFormat: #"%d:%d", oreBlkOff, minBlkOff]];
Same with blockOnText and flightTimeText, so there is no problem there, but this is not really what I need right?
HOW CAN I GET THE VALUE OF THE TEXTFIELD AND STORE THE VALUE IN VARIABLES THAT CAN BE USED TO DO CALCULATION?
HOW DO I GET THE FIRST TO DIGITS AND LAST TO DIGITS FROM THE VARIABLES SO I CAN USE THEM AS HOURS AND MINUTES FOR MY CALCULATION?
I WOULD LIKE TO BE ABLE TO TYPE THE VALUE IN THE TEXTFIELD, PRESS "ENTER" OR "RETURN" AND GET THE VALUE ASSIGNED IN THE VARIABLE.
IS THIS THE CORRECT WAY OR I'M JUST GOING THE WRONG WAY IN THIS.
IN ANOTHER PROGRAM I DID IN VISUAL BASIC THAT WAS THE WAY I USED.
THANK YOU VERY MUCH IN ADVANCE FOR YOU HELP!

To get the int value from text field you'd use integerValue or floatValue for float. But you should definitely check out the date/time controls in cocoa.
Ok, if I didn't miss the point of your long question...
You have a text field with something like #"2345:8743" and you want to get the two numbers in int variables (a=2345, b=8743).
First you need to get these two text representations of your numbers in two NSStrings. You can do it like this:
NSString * yourString = #"2345:8743";
NSString *stringA = [yourString substringToIndex:4]; //stringA = #"2345"
NSString *stringB = [yourString substringFromIndex:5]; //stringB = #"8743";
Now to get the in values, just do:
int a = [stringA intValue];
int b = [stringB intValue];
Let me know if that is helpful to you.
I am facing a problem while getting contents of cell using JXL api, if I am using formula
in xls sheet. Right now I am using formula - IF($L10="","",+ROUND($L10*1.375,3)) in each
cell but when the cell value is blank i am getting junk charactes when i call cell.getContents() method, the code snip is as follows - >>
Workbook = Workbook.getWorkbook(p_sourceFile);
excelsheet = workbook.getSheet(0);
for (int row = 1; row < noOfRows; row++)
{
cell = excelsheet.getCell(col, row);
content = cell.getContents();
System.out.println("content-" + content); //Is giving me junk character ? when the cell value is blank.
...
It will be a great help if anyone can help me !!!
Regards,
Amit
Try this:
NumberFormulaCell cell = (NumberFormulaCell) excelsheet.getCell(col, row);
content = cell.getValue();
From the JavaDocs for Cell.getContents():
Quick and dirty function to return the contents of this cell as a string. For more complex manipulation of the contents, it is necessary to cast this interface to correct subinterface
The necessary subinterface for a numerical formula is NumberFormulaCell. If you want to get the formula as a String then call cell.getFormula().
I'm not sure if I'm really answering your question here or not. If I'm not, could you post these junk characters that get printed out, please?
