Error in IfEx block

#1 · August 21, 2023, 12:24 pm

Hi,

I'm creating an application and I'm encountering an issue with a code block where a series of IF statements are being used.

I need to check a code within the box and color the box based on the selected content.

However, even though the code is not the same, the program still executes the code within the IF condition.

Attached is the image of the error.

My guess is that it looks like both strings are being interpreted as numeric expressions, so

828905 - 1 = 828904

and

828906 - 2 = 828904

And so they are seen as equal in the IfEx action. I don't know enough to suggest the how to stop this, but I imagine someone with more experience than me in VisualNEO Win will know a solution?

I put the variable as TEXT, but I have the same problem

@nikyred, I think @susan is right. Please prepend "!" to the variables value to avoid VisualNEO Win doing the math operation.

Example:

SetVar "[myVar]" "!828905 - 1"

Please, let me know if this solves the issue.
Regards.

I tried to put ! , but it does not work.

Can I send you the TEST file so I could check it?

the only thing if I can send it to you privately

First, your conditions are written incorrectly.
Should be:

IfEx ""

Else

EndIf

But not:

IfEx ""

Else

Else

Else

EndIf

Replace Else with EndIf everywhere. And let me know.

Secondly, if you think that something is not working correctly, use AlertBox . For example:

IfEx ”[Pressa50_PN1] = 963243-1" 
AlertBox "" "[Pressa50_PN1]" 
SetObjectFill"Pressa50_PN1“ "34,113,179" "Solid" "False" 
SetObjectFont "Pressa50_PN1" "Black" "Arial" "14" "Normal" "ANSI_CHARSET" 
EndIf

Thank you for your suggestion.

I tried to edit but it didn't solve the problem.
but I replaced this "-" symbol with this "_" and it works.

So it is confirmed that VisualNeo is likely doing a mathematical calculation.
I tried adding the "!" symbol to the variable. but it doesn't resolve.

I will try to make the selection in number and not in Text, in the box. So then in the program in the condition comparison with a number and not with a Text

Ifex isn't need here. It is for multiple conditions. You can use:

if

else

endif

instead.

Alertbox shows subtraction or a whole line? I have a whole line.

@nikyred

I think @mishem has the right reason ... unlike some other languages, NeoScript does NOT support multiple Else code blocks within If and IfEx commands.

This small example worked for me ...

...AlertBox "Selection" "[ListBox1]"

IfEx "[ListBox1] = 828906-1"
   AlertBox "828906-1" "selected"
   Return
EndIf

IfEx "[ListBox1] = 963142-2"
   AlertBox "963142-2" "selected"
   Return
EndIf

... where my ListBox had just two entries viz. 828906-1 and 963142-2 (ok, I was too lazy to add more entries).

So, in your pub, add the appropriate commands in place of the AlertBox (after it is seen to work for you).

In case it is relevant, I found this in the definition of the SetVar action in the Help. I presume attempting to evaluate a string as a mathematical formula might apply to strings in contexts beyond the SetVar action?

Did a little experiment. The AlertBox displays the correct variable value as 828906-2.

IfEx performs a mathematical operation on both the variable and the value. So it should be written like this:

IfEx "![ComboBox1]=!828906-2"

Hi,

Thanks for everyone's support.

I tried your advice but with no success.

I then chose to transform the Box selection into a numeric value. In this case everything works :)
