How to implrment “Spin control”

How to implrment “Spin control”

Chang Chi 61

Hi,

I need help getting “spin control” working in Dialog box.

I chose to use static box and spin control;

They are a part of modeless dialog box

I set SETBUDDY, and AUTOBUDDY to be true

I setBuddy hStatic10 and hSpin2.

I entered “ABC1”, “DEF5”, GHL10, QRS15 to Static box

I entered range to be 1 to 3; and initial position to be 2

These commands don’t seem to work.

When I press the arrow the static box shows 1,2,3 etc

Would someone tell me where I made mistakes and errors.

I am not familiar with how things are done with spin control.

Is there a book or article that shows how to do the spin control, in C language?

I work with C-language on window 11, using Visual Studio 2022

Thank you very much in advance

That is exactly what the posted code is supposed to do. The buddy window displays the text representation of the numeric position of the spin control.

Hi, RLWA32

I am hoping that you may remember me; I am one of many you have helped

tremendously and so generously in the past.

I like to enter 10 items in text box, in this case “IDC_STATIC10”, and press “up” or “down” arrow of spin control, and want different item to show up on the Static panel and select one of them. I then press “OK” button to commence computation process.

Would you help me to achieve this, Please?

I try to learn this in anyway I can in internet.

I think there must be a right way to do “spin control”

Thank you, RLWA32, as always

To change the text, you must remove UDS_SETBUDDYINT

I tested in old SDK sample updown.c with a string array and SetDlgItemText at the end of UDN_DELTAPOS
