HM Error Message Handling

Altair Forum User

I have made the HM as server and I have written a small application as client,

Client will send request to the HM like loading file,hiding  the assembly etc via sockets and it is working fine.

 

I have written a function to query the xyz of the node. It is working fine as long as the node is in the model.

 

My script has this:

 

if{ catch[ { set nodeXYZ [hm_getentityvalue nodes $nodeID 'x' 0] } errCode] } {

tk_messageBox -message 'Node not found'

}

 

where $nodeID contains the id of the node.

If it is not there in the model I want to show my own error message but now HM shows the Application Error message which I dont want to show.

 

How can I make not to show the Application Error messages in HM?

I tired hm_blockerrormessage 1 and hm_blockmessages 1, but no use.

 

If I use in HM command window , I'm getting the expected result [ i.,e it shows the error message 'Node not found' ]

But It does not work when I launch HM as server...

Hi

I think hm will not throw an error to server, just a message

anyway i think your code should be: 

 

if {[hm_entityinfo exist nodes $nodeID]} {

      lassign [expr [hm_nodevalue $nodeID]] x y z

      #return value to client  return [list $x $y $z]

} else {

      tk_messageBox -title 'Error node not found' -message 'Node $nodeID not found in current model' -icon error

      #return a message to client return '...'

}

 

 

no need 'hm_blockerrormessages' because above code will not raise any error

 

 

ps: your 'catch' command look strange

usually i will write :

if {[ catch {set nodeXYZ ... } ]} {

#show error

}
