Hi,

I have 10 command buttons which is linked to a single callback function.But I need to pass a variable parameter for each command button.ie command button1( var=1),command button( var=2) etc... How can I do it.

Also I am going to create a thread everytime i click on command button.Is this a good idea to implement in the above mentioned way?

Please reply..

I could solve it by using creating an array (arr) with known values. and calling

SetCtrlAttribute( gPanelHandle,PANEL_COMMANDBUTTON_22,ATTR_CALLBACK_DATA,(arr+index));

for each command button.

This will solve the problem.

sorry for psoting it bfore thinkning
