Define maxium length iproperty

[mcatalanbs]

Hi everyone,

I want to know if it is possible to define the maxiium length of characteres in a custom iporperty.

I mean, I want to create a curstom iproperty and the maxium value text is 2 characters...

"My Descripticion"=MD

Thank you in advance

If you want to check the length of a string or in other words how many characters use the Len string function. Official documentation is here 

Use

Dim CustomiProp as String = "MD"
'Check String Length
Messagebox.Show(Len(CustomiProp)

If you want to check each string value for length then you can build an if statement around the string function and insert into a larger function for repetitive use. If you need assistance on then please let us know.

I don't think there is a elegant way to do this. But depending on your Inventor version you could create the following iLogic rule. Then trigger it on iProperty changes. (Inventor version is important because the trigger is not there in older versions of Inventor)  The problem with this method is that you will only get a messagebox after you have closed the iProperty dialog...

Dim myDescription = iProperties.Value("Custom", "My Descripticion")
If (myDescription.length > 2) Then
	MsgBox("iProperty 'My Descripticion' is to long. Will make it shorter for you!")
	iProperties.Value("Custom", "My Descripticion") = myDescription.Substring(0, 2)
End If
