I'm new to writing formulas in infopath and can't see what I'm doing wrong with the following:
if (contains(userName(), "\"))
{
substring-after(userName(), "\")
}
else
}
userName()
}
The above is erroring on the first brace
I can write 2 rules to achieve the same thing but would like to use the above approach if it can be done!?
This a form load rule in infoPath 2010
Found this which seems to explain it, in case anyone else has the same issue...

I'm currently developping a multi languages application using the tap-i18n package. I wonder how I can translate errors.
I can grab the code and then display a custom message that I would have written to the translation file before.
But I saw on this post there is a better way of doing this with another i18n package.
Does anyone know if there is way of doing something like with tap-i18n ?
EDIT : For now I'm doing something like this :
Meteor.call('createNewUser', newUser, function (error, ret)
{
if (!error)
displayError(TAPi18n.__('success'), TAPi18n.__('new_user_success'), TAPi18n.__('ok'), "btn-success btn-lg", "success-popup");
else
{
switch (error.error)
{
case 403:
displayError(TAPi18n.__('danger'), TAPi18n.__('new_user_already_exist'), TAPi18n.__('ok'), "btn-danger btn-lg", "danger-popup");
break;
default:
displayError(TAPi18n.__('danger'), TAPi18n.__('new_user_error'), TAPi18n.__('ok'), "btn-danger btn-lg", "danger-popup");
break;
}
}
});
My answer might be a bit off-topic, but do you mean application errors? If so, you shouldn't really return that to the users, as this could constitute a security flaw, giving them too much information.
From OWASP: https://www.owasp.org/index.php/Error_Handling
Thus, you might want to handle the errors, and give the users exactly what you want them to know.
Just include the error messages in your translation, and proceed as with normal strings to translate.
I hope this is of some help :).
EDIT:
I understand now what you mean. As far as I know, there's no such option, as there is with just-i18n. As a suggestion for unbloating the code a bit, you could use a helper function such as:
function t(keyToTranslate){
return TAPi18n.__(keyToTranslate)
}
And in the code:
displayError(t('danger'), t('new_user_already_exist'), t('ok'), "btn-danger btn-lg", "danger-popup");
A bit naive suggestion, but there's no functionality to map the errors in this package, as far as I know. The way you're handling it seems correct to me.
I have a large complex ASP.net WebForm website that I'm working on a visual redesign and am trying to think of good ways to exercise all the code paths in the website so I can see how things look with the redesign.
For example lets say I have a message that only gets displayed if there is an error which rarely happens. Here is an example of what my code might look like:
if (someErrorCondition) {
someControl.Visible = true;
} else {
someOtherControl.Visible = true;
}
This might not be a good way of doing things, but this is a good example of my existing code base I have to work with.
Let us assume for the sake of simplicity that I already have a way of testing one part of the if. The problem is exercising the other part without going through a lot of trouble to setup my environment to create an error.
One idea I had was to extract someErrorCondition into a method and in that method check for some session or request key to see if I want to fake a failure. Maybe wrap it in an #if DEBUG block so that it won't be compiled for production.
Any other ideas for how I might go about testing unusual code blocks on an ASP.net website so I can make sure nothing got left out in the redesign?
I believe the best solution is always the most simple. Since you obviously have access to the code, do a search for the Visible property for each form element within Visual Studio and set each one to true to see how it looks. Once you make the design change then un-comment the original code.
Example:
if (someErrorCondition) {
someControl.Visible = true;
} else {
someOtherControl.Visible = true;
}
TO
/* if (someErrorCondition) {
someControl.Visible = true;
} else {
someOtherControl.Visible = true;
}*/ someControl.Visible = true;
This is not good for testing proper behavior of the form, but will let you see how each element looks for visual design purposes.
as I probably do not describe the problem in the right terms, I was not able to get an answer with google. Please excuse!
In the following code, I would like to replace 'hardcoded' identifier COMMENT with the variable editedField. How to do that?
var editedField:String = event.dataField;
if (model.multipleProcessingData[i][editedInformationProductNO].COMMENT != null{
...
}
Make sure you wrap this in try/catch block for NPE's, as you'll eventually find one with this many [] accessors.
A better, more OOP, would be to have an accessor function on your model that you can pass your data to:
model.getEditedField(i, editedInformatioNProductNO, editedField)
This will make it easier to troubleshoot and add good error messages to your app if things don't turn out like you expected.
var editedField:String = event.dataField;
if (model.multipleProcessingData[i][editedInformationProductNO][editedField] != null{
...
}
Anyone know how to use CertificateWarningHandler in WatiN?
I've got as far as...
IE ie = new IE("https://mysite.aspx");
CertificateWarningHandler cwh = new CertificateWarningHandler(CertificateWarningHandler.ButtonsEnum.Yes);
cwh.HandleDialog(new Window(ie.hWnd));
... which does precisely nothing.
On a more general note, how on earth do you people manage to use this tool? The documentation is nearly useless, and there doesn't seem to be any decent resource online. I must be missing something because it's taken me about half an hour to write 3 lines of code that don't even work.
I'm using something similar to what Saar is using and it works fine (my tests are cross-browser).
//Override security warning in browser
{
if (Browser.Link(Find.ById("overridelink")).Exists)
{
Browser.Link(Find.ById("overridelink")).Click();
Browser.WaitForComplete();
}
else
{
Browser.WaitForComplete();
} //end else
}
I'm not a developer, and I've found that there's plenty of information out there on WatiN and others post code samples and the like that are really helpful. Google is one of my best friends when it comes to finding WatiN help. You'll get the hang of it.
have you tried following already?
ie.DialogWatcher.Add(cwh);
or just
ie.DialogWatcher.Add(new CertificateWarningHandler());
Update: After comment.
Actually this works for me.
further may be following will help
Browser browser = ie;
if (browser.Links.Exists("overridelink"))
{
browser.Link("overridelink").Click();
}
I've 3 .jsp files. index.jsp and sqrtcalculator.jsp and error.jsp.
In index.jsp there's a text field and a button. In sqrtcalculator.jps there's the, well, calculator.
Now, when I leave the field empty and press the button, an expection is called, because the field is empty. And I can then reroute to an individual error.jsp site to display the errors, and exception stack like
<%= request.getAttribute("javax.servlet.error.request_uri") %>
<%= exception.getMessage() %>
<%= exception %>
etc.
Problem is, when I enter -5 in the textfield, I can't get an exception, because Math.sqrt(-5) doesn't return an error but "NaN".
How can I force it to be an exception? The idea is to reroute the user to an individual error.jsp and displaying the errors. But like I said Math.sqrt(-5) doesn't return errors or exceptions but "NaN" textstring.
I don't want something like this just FYI
<%if (NaN){
%>
<p>Nope, Square root from negative numbers is not defined!</p>
<%}
%>
Warning, the test for NaN in the previous answer is wrong (NaN is NOT equal to itself). In Java the better way to test for NaN is
if (Double.isNaN(answer)) {
// throw exception
}
alternatively
if (answer != answer) {
}
While this second version will work, it is sure to puzzle those not aware of the curious behaviour of NaN.
How about:
if (x >= 0.0) {
return Math.sqrt(x);
} else {
throw new ArithmeticException("Square root from negative numbers is not defined!");
}
Note that ArithmeticException is a subclass of RuntimeException and therefore does not need to be declared in the throws clause of your function.
It's presumably returning NaN because square roots of negative numbers are indeed defined, they're just not real numbers. Is there any reason you can't do this?
if(Double.isNaN(answer))
throw new ArithmeticException("Answer unreal");
That should tickle your exception handling code, but the source line might just be a few lines off. I've never written JSP, but that makes sense in Java.
I'm not very good in jsp but afaik you should be able to use basic java code.. so i'd check my result for NaN and throw an exception
if (NaN == result)
throw new Exception("NaN");
you'll have to adjust the if ;)
I would ask why you're using scriptlets in JSPs.
If your app really is just three pages (index.jsp and sqrtcalculator.jsp and error.jsp), then maybe it's justifiable.
But my general recommendation would be to stay away from scriptlet code in JSPs and prefer JSTL. Have those calculations done in a server-side component, using a Model-2 MVC arrangement.
If your app really consists of only three pages, re-architecting it to use Model-2 MVC would not be difficult to do. You might find that it's far more extensible that way. If you're unfamiliar with Model-2 MVC you can read about it here. If you're familiar with it, this might be a self-contained problem that's small enough to let you see where it could provide some value in future projects.
Another thought would be to add complex numbers to your calculator, because the square root of negative numbers is indeed a valid concept. It just requires imaginary numbers. Maybe your calculator needs to be extended to maximize usefulness.
I can't seem to get it to work....
if (d < 0){
throw new Exception("Negative Numbers not possible!");
}
d is a double read via d_string = request.getParameter("numberfromtextfield") and converted to double via double d = Double.parseDouble(d_string);.
This is what Eclipse is telling me: http://pastebin.ca/1691409
