回复： How can I seach a constant name or a label on the control panel?

[Robin Liu]

Hi everyone，

There are so many controls on the panel, how can I  location one of them through their constant name or label?

thank you.

To retrieve the constant name assigned to a control in the UIR editor you can use GetCtrlAttribute (..., ..., ATTR_CONSTANT_NAME, ...);

This can be integrated in a loop that iterates on all controls in a panel, this way:

    GetPanelAttribute (panelHandle, ATTR_PANEL_FIRST_CTRL, &next);
    while (next) {
        // Your code here

        // ...

        // Verify wether there are more controls to scan

        GetCtrlAttribute (panelHandle, next, ATTR_NEXT_CTRL, &next);
    }

The relevant question, nevertheless, is: are you *sure* you absolutely need to run this way? If you know which control you must locate and operate on, you can save this name in an array and use the array elements instead:

// Defining a global array of control IDs

int   ctrl[10];

// Saving relevan control IDs

ctrl[0] = PANEL_NUMERIC;

ctrl[1] = PANEL2_NUMERIC;

and so on...

// Using saved control IDs

SetCtrlVal (panelHancle, ctrl[0], value);

I got.

--------------- 

Constant Prefix—Valid for panels and menu bars

Constant Name—Valid for controls, menus, and menu items

Prefix + Constant Name—Valid for all

Callback Function Name—Valid for all, except menu bars

Label—Valid for all, except menu bars

sorry, the question is not described clearly.

Using the Find command to locate an object in user interface resource (.uir) 

 , I fail to find the object because of misunderstanding the following choice:

• Constant Prefix—Valid for panels and menu bars
• Constant Name—Valid for controls, menus, and menu items
• Prefix + Constant Name—Valid for all
• Callback Function Name—Valid for all, except menu bars
• Label—Valid for all, except menu bars.

now it's ok.
