HI,
I need some suggestion in achieving this concept, I am not sure if some thing like is already exist or some one has implemented it. My requirement is like the user will select an item from a Combo box from the front panel, according to the user selection the next screen should be displayed. for example if user selects "Item 1" from combo box, Vi will search the selection in a file and gets the Next UI Configuration like below.
"Display name", "Data Type", "Restriction"
[Item 1]
"Serialno", "Text", "8"
"type", "List", "Internal, external"
"noofcycle", "numeric", 0
according to the file I need to place this control on the front panel during runtime. needs your thoughts on this
Thanks in advance

Hi,
My requirement is that User is allowed to change the number of parameters in the file for each item and he can a new items also in the file. so my controls on the screen is unknown until user selects. as you said if i make the control invisible and visible, one problem I will end up is like after reading the file only i will know the list of controls to place like string , listbox, numeric or numeric string list. how do I handle this?
Thanks in advance

We use table in one of instrument.
Method consists of set of predefined actions, like MoveToSample, Syringe, Delay. Each action has different set of parameters. For example:
- MoveToSample action has X, Y and Z positions
- Syringe has Infuse/Withdraw, Volume and Speed
- Delay has Time.
One action uses one line in the table. Operator can type into table. In case of predefined settings, like any cell in first column, operator makes right click by mouse and gets popup dialog with list "MoveToSample/Syringe/Delay". In case of Syringe action in second row operator gets "Infuse/Withdraw" list. Additionally, application show action's hint.
Method could be saved to/loaded from file and validated.
