Finding Controls on a Panel

[John Stuart]

I am writing several configuration screens for various tests and I would
like to find/create a function that would find all the controls on a
page and one by one save them, this is easy enough, except I have no way
of knowing what type of control I have.

I plan on starting with the panel 1 and setting the active control ++
until I receive an error. As the UIR always maintains the controls from
1 up in a contiguos fashon. My problem is I need a function like
GetControlType so I know if I am dealing with a check box or a table.

Any Ideas??

if you have a diferent label for each control and a table on your source code
that contain all labels with they respective type, than you can discover
the type using getControlAttribute - control Label text and so verifying
the table.

According to CVI documentation the right way should be this one:

GetPanelAttribute (PANEL, ATTR_PANEL_FIRST_CTRL, &ctl);
// Find first control in the panel
while (TRUE) {
// Find control's style
GetCtrlAttribute (PANEL, ctl, ATTR_CTRL_STYLE, &style);
switch (style) {
case CTRL_NUMERIC:
// Your code to retrieve and save control's value
break;
// Other styles to control here
//
default:
// All styles not interesting: those ctls are simply skipped
break;
}
// Look for next control in the panel
GetCtrlAttribute (PANEL, ctl, ATTR_NEXT_CTRL, &ctl);
if (!ctl) break; // End of panel controls
}

Thanks,

This is how I implemented it. Could you please tell me the location of this
information in the CVI Documentation. I found it by accident in the Help
file. I would prefer to find information like this in a printed manual so I
can read it offline.

Sorry, I too found these informations in the help files.
You can find some detail in the User Interface Reference Manual, but only a
little regarding the matter we are discussing about. I spent a lot of time
in temptative coding due to lack in the documentation, but found NI support
useful and ready to answer to my questions.
