I want static text to be printed only if any one or more of the textField has a value.
I have tried with following code but goal is not achieved. Following code is not working when all the textField is empty except the last one (HAEMATOLOGY_BASOPHILS). I think with following approach once boolean false is returned rest of the logical or gate is not getting executed.
<printWhenExpression>< ![CDATA[((!$F{HAEMATOLOGY_NEUTROPHILS}.isEmpty()) || (!$F{HAEMATOLOGY_EOSINOPHILS}.isEmpty()) || (!$F{HAEMATOLOGY_BASOPHILS}.isEmpty()))]]></printWhenExpression>
<text><![CDATA[Differential Count]]></text>
PS : My english is not good. So, sorry for the grammatical error.

Good day,
I'm trying in AnyLogic to make block "Ped Select Output" (from Pedestrian library) select output based on the received message, using the command in conditions table receive("go");. This block is located in Main, while the message is supposed to be sent from the agent tab (MyAgent) using the command send("go", main.pedSource);. Yet if I try to launch this model I get the error "Type mismatch, cannot convert void to boolean". I believe I have incorrectly selected one of the commands (or maybe both), thus I hope for advice about it. Thanks in advance for the answer.
P.s. check screenshots, for more detailed information.
P.p.s. the model, that is presented on screenshots is just an oversimplified example of the real model (that's why 4 out of 5 outputs of the block are connected to one place).
main
agent
Each condition in the selectoutput should return a boolean... a boolean can be true or false
Some example of booleans are 3==2, 5>4, agent.priority==1, etc
These things are booleand because they are true or false
you are putting in the condition a function that doesn't return anything (receive) and I have absolutely no idea what is in your head that would suggest that this might work in any way...
I suggest you add a variable in your ped agent that defines what the pedestrian should do...
I have the following suppression formula in the details section:
{JCJM.udRough} <= #1/1/2013 12:00#
AND
{JCJM.udTrim} <= #1/1/2013 12:00#
and it works. However, I also need it to suppress if the udRough or udTrim field is blank. When I try to add
OR {JCJM.udRough}=""
it says that a date-time is expected where the blank quotes are.
Can someone please help?
As a general rule in CR, if a field can be null then you should explicitly check for that case first in a formula, otherwise it will not evaluate properly. Otherwise, CR will treat it like an unhandled exception.
So in your case, CR is short-circuit evaluating the expression {JCJM.udRough}<=#1/1/2013 12:00# as the very first thing, sees that the field is null, and stops evaluating the rest of the formula since it has encountered an exception.
What you need is:
(isnull({JCJM.udRough}) or {JCJM.udRough} <= #1/1/2013 12:00#)
and (isnull({JCJM.udTrim}) or {JCJM.udTrim} <= #1/1/2013 12:00#)
Try
if ISNULL({JCJM.udRough})
Then true
else false
This is from my understanding from your question if you are searching for something different let me know will try to answer it.
I'm using Opa for a school project in which there has to be some synchronization of a textfield between several users. The easy way to solve this, is to transmit the complete field whenever there is a change performed by one of the users. The better way is of course to only transmit the changes.
My idea was to use the caret position in the textfield. As a user types, one can get the last typed character based on the caret position (simply the character before the caret). A DOM element has an easy-to-use field for this called selectionStart. I have this small Javascript for this:
document.getElementById('content').selectionStart
which correctly returns 5 if the caret stands at the fifth character in the field. In Opa, I cannot use selectionStart on either a DOM or a dom_element so I thought I'd write a small plugin. The result is this:
##extern-type dom_element
##register jsGetCaretPosition: dom_element -> int
##args(node)
{
return node.selectionStart;
}
This compiles with the opp-builder without any problem and when I put this small line of code in my Opa script:
#pos = %%caret.jsGetCaretPosition%%(Dom.of_selection(Dom.select_id("content")));
that also compiles without problems. However, when I run the script, it always returns "undefined" and I have no idea what I'm doing wrong. I've looked in the API and Dom.of_selection(Dom.select_id("content")) looked like the correct way to get the corresponding dom_element typed data to give to the plugin. The fact that the plugin returns "undefined" seems to suggest that the selected element does not know the member "selectionStart" eventhough my testcode in Javascript suggest otherwise. Anyone can help?
In Opa dom_element are the results of jQuery selection (i.e. an array of dom nodes). So if I well understood your program you should write something like node[0].selectionStart instead of node.selectionStart.
Moreover you should take care of empty selection and selection which doesn't contains textarea node (without selectionStart property). Perhaps the right code is tmp == undefined ? -1 : tmp = node[0].selectionStart == undefined ? -1 : tmp
The application I work on is using a Crystal Reports to present reports to the user. I am using Visual 2010, but the report was created by a previous employee some years back using Visual2005.
The basic setup is that the client application make a request to the server that uses a xsd that define the data-set it sends back. Generally this work like expected, but I am having some problems with evaluating booleans.
A recent task consider of adding the dataset with a field name TrueWeekday that control if certain numbers should be printed out or not depending on if a date is a regular weekday or have some special local meaning that might affect the sampled data. The data is always used in some formulas so I can not exclude it from the dataset.
My first attempt involved defining the new field as a boolean and in the formula for the report I wrote
if {Header.TrueWeekday} then
CStr({Detail.Flow})
else
""
This had the result that no matter if the value in TrueWeekday was false or true the flow was presented. I debuged the server to verify that the variable indeed got the expected value so the problem happened in the Crystal Reports or in the transfer of data to Crystal Reports.
To solve this particular problem within the timeconstraints of the task I changed the field to the type string and wrote
if {Header.TrueWeekday} = "false" then
CStr({Detail.Flow})
else
""
This worked like a charm.
My problem here is not urgent since I have a working solution, but I am worried that this problem might create more subtle dataintrigity problems.
What might be the cause of this and how do I solve it?
Header.TrueWeekday is probably being passed as a string so that when you do if {Header.TrueWeekday} its testing a string as a boolean in which case if the string contains anything it evaluates to true and thus causes your problem
Work in a different project made me realize that .Net is probably serializing the boolean as the text string true/false. If then Crystal Reports does sloppy import and only check
input != 0
you will get the result that both true and false map to true after the transfer.
I'm creating a invoice crystal report for sage mas 500 AR module. In it, I'm attempting to add the tarinvoice.balance field with the following formula:
if {tarPrintInvcHdrWrk.Posted} = 1 then
ToText({tarInvoice.Balance})
I'm assuming that when the {tarPrintInvcHdrWrk.Posted} = 1 conditional statement holds FALSE, it doesn't attempt to pull the invoice field because when I remove the formula from the report, the form displays correctly without it.
When the conditional statement renders true in the report, the balance fields behaves correctly. However, with the formula renders FALSE in the CR form, the entire crystal report bombs and displays blank. Any ideas why or what I'm doing wrong?
Just tried setting everything to zero and the report still bombs. I'm starting to think its more of a query error in the report. I wish there was a way to exclude the field in the query when posted = 0.
With tarinvoice.balance removed when the posted = 0, the report works fine.
With tarinvoice.balance included and posted = 1, report works fine.
With tarinvoice.balance included and posted =0, report bombs.
I believe the conditional statement fails immediately if you encounter a NULL, so your formula needs to test IsNull({tarPrintInvcHdrWrk.Posted}) before it tests equality with "1".
You can change the way Crystal handles a null value for a value in a formula. At the top of the Formula Workshop there is a drop down box that usually says "Exceptions For Nulls".
Change this to the other option "Default Values For Nulls" and your formula should no longer bomb out. You used to be able to specify the what the default values applied were, but more recent versions of Crystal have these hard coded.
Search the help for "Null Treatment" for a table showing them.
I modified the formula to this:
if isnull({tarPrintInvcHdrWrk.Posted}) = FALSE then
if {tarPrintInvcHdrWrk.Posted} = 1 then
if isnull({tarInvoice.Balance}) = FALSE then
ToText({tarInvoice.Balance})
else
"0.00"
else
"0.0"
else
"0"
The crystal report still bombs.. Nevertheless, it does show "0" in the appropriate space.
I saw a suggestion on Exp.Exch to try putting the field into a variable before converting it to text.
e.g.
NumberVar InvoiceBalance;
If isnull({tarInvoice.Balance}) then
InvoiceBalance := 0
Else
InvoiceBalance := {tarInvoice.Balance};
If {tarPrintInvcHdrWrk.Posted} = 1 then
ToText(InvoiceBalance);
I also tried to recreate your problem, since I have see similar things before.
No luck though trying with CR 8.5 & XI R2. Perhpas it has to do with linked tables as well, since I only tried on a simple single table.
I have also seen similar behaviour when using a formula within a Running Total - they do not like nulls at all!
If you put {tarInvoice.Balance} directly on report (into details "debug" section - often needed, don't forget supress it in production :)), what values it displays or does report become empty?
Maybe you have Suppress If Blank section on your report. Try to put: Else " "
if isnull({tarPrintInvcHdrWrk.Posted}) or {tarPrintInvcHdrWrk.Posted}=0 then
" "
else
if {tarPrintInvcHdrWrk.Posted} = 1 then
ToText({tarInvoice.Balance})
else
" "
I have trouble with this kind of field when making reports to export to excel. A field with no data in will pull all columns to the right of it over to "fill the gap".
