You need to provide considerably more details of the code you are using and exactly what you are trying to do. As it stands it is impossible to suggest anything useful.

Anywhere means nothing.
What do you want to do, exactly ?
What is or what kind of data in your window ?
How is it represented ?
What kind of notes you want to add ?
What relation has the note and the data ?
Do you have an example of something similar you want to do ?
Without more details...
I'd handle a click or double click event, open a modal popup window with a text box, and on the OK button, save the note whereever you want to save the note.

Why don't the enumeration objects get recognized unless the enumeration is defined in the same header file where the enumeration object is created? If the enumeration is in a different header file I get an
"Error C3646 'PC': unknown override specifier " error. I`m including the header file where enumeration is defined in the header where the enum object is created.

Thank you Victor. I will change the object name to lower caps and see if the error goes away

Since it is demonstrated that the community has no (technical) interest, or perhaps lacks knowledge in helping in resolving the issue , hence this post, as is , has no change to be resolved here and is also unwelcomed here ,

Wrong!!! YOU don't get to dictate what you can or cannot post here. That's for the community and moderators to decide. This forum is specifically for standardC/C++ (with the addition of MS MFC), because that's what the moderators wanted. There's no mention of QT, or WxWidgets or any other C++ frameworks.
As I said in one of my earlier posts, get a copy Stroustrup: The C++ Programming Language (4th Edition) If your question can't be covered by the material therein, then ITS NOT A C++ QUESTION!!!. I only have the 2nd edition of that book, and QT isn't covered at all. I'm sure that it's not covered in the 4th edition either. So, as always, this question belongs in a forum that's dedicated to QT and its use, not here!

Hi,
In my dialog i followed the link below to solve the flicker issue. It worked.
I am continuously capturing and updating an area of dialog.
currently, i do:
Invalidate()
UpdateWindow()
is there a faster way to repaint?. like RedrawWindow(), etc. Are they handled by the wm_paint?.

2 Things:
1) Please don't repost if your question does not appear immediately: all of these went to moderation and required a human being to review them for publication. In order to prevent you being kicked off as a spammer, both had to be accepted, and then I have to clean up the spares. Have a little patience, please!
I've deleted the 3 identical spares ...
2) Don't post this under Quick Answers - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.
However, given that the article is 22 years old it's unlikely that anyone is going to know or remember details of how it works!

I'm using a CIPAddressCtrl which gets filled with a device's IP. The user can edit this IP and I need to make sure none of the fields (octets) are blank if the user wants to update the device with the new IP. If any are blank and the user tries to update (with a click of a button), then there will be an error.
I see there is a SetFieldFocus that can set the focus if an octet is blank, but I'm not sure if it's useful for what I need or how to use it in my case. Is there any work around to achieve this?
Thanks.

In order to validate the use input, call the GetAddress method and check its return value. See the documentation: CIPAddressCtrl Class | Microsoft Learn[^].

Tried that already. GetAddress doesn't tell you whether or not an octet is blank. If you do GetAddress and get the four octets and one of them is blank, then it's just a zero. However, it could also mean that the user could have entered zero.
The IPM_GETADDRESS message returns the number of non-blank fields so that'll probably work for me unless anyone has any other ideas.
|
|
|
|
|
DWORD dwIPAddr;
iNonBlankOctets = ::SendMessage(hWnd, IPM_GETADDRESS, 0, (LPARAM)&dwIPAddr);
This worked for me.

But how would you differentiate between an empty octet and an octet containing 0?

Not exactly sure how to tell if specific octets are blank or 0.
In my case, making sure iNonBlankOctets is never less than the total number of octets is sufficient validation so if any octets are blank, then there's an error.

The return value of IPM_GETADDRESS is a DWORD that is broken up into 4 pieces, one for each of the four octets. There is no count.
A possibly better option would be to call GetWindowText() on the CIPAddressCtrl's control. Getting the string representation of the IP address would allow you to parse and validate the octets. You would still get 0 for empty ones, though.

Tried these...
public class Program {
static async Task Main()
{ }
}
static int Main()
{
No luck , I'm afraid ...

I'm afraid you will have to learn basic syntax of C++ language. Get a good book and start going through it.

That's C# code, not C/C++. You posted this in the wrong forum.
But I see you already posted this elsewhere and received answers to it, so reposting this was redundant.
