Salutes,
GDI / GDIP / OpenGL, windows API, and I still find it hard tackling with. Search results for changing cursor icon to hand on hovering on a link_label didn't afford except this solution came up by jaafar-tribak .

I get this error from compiler :
Compiler Error
The code in this project must be updated for use on 64-bit systems. Please review and update Declare statements and then mark them with PtrSafe attribute.

● If someone could help converting it into 64-bit, with many thanks
The code is picked from this Thread on this Forum, right at the end of the thread (Userform Hand Mouse Icon when scroll over buttons)

Excel Facts

Which lookup functions find a value equal or greater than the lookup value?
MATCH uses -1 to find larger value (lookup table must be sorted ZA). XLOOKUP uses 1 to find values greater and does not need to be sorted.
See one of the Similar Threads listing at the bottom of your thread. Or review this one
or this site for the whole enchilada

Thanks man much appreciated , I couldn't find a way to send you a message. I was hoping a label control could have such an effect, I use links in my userforms, each link in a separate label. I hope this would be possible.
★ I owe you so much, and I'd like to share my projs with you in the near future.
thank you @Jaafar Tribak

Yes. we can amend the class code and apply a similar technique to label controls so that they look and behave just like real Hyperlinks including changing the hyperlink text hover and visited colors and hand cursor.
Here is an example:

Hi @ammer

I just noticed a stealth problem in the Class code posted above: If the user closes the form using the keyboard, the code execution won't break out of the temporary loop. This is an unlikely, albeit serious, scenario that should be catered for.

So please, ignore the previous Class code and use the following one to which I have incorporated the necessary changes.

============
Maaan it looks like you're really deeply experienced in digging the outmost of API libs! And not just for 32-bit but also for 64-bit configurations too. This deep understanding is obviously clarified by the rhythm of the tidy clean code definitely, that made me --the one whom never tackled in such libs to-- put_in even some more additions to my likings!

By your ultimate contribution I can say I've got everything I needed for the porj final touches I’ve been building. And not just that but also it gave me a quick vision, & know-how to deal with & use API libs in just few moments.
● My background experience is in php, JavaScript, & websites databases, and excel came thereafter from necessity.

★ I’ll be in touch frequently, your share will never be forgotten. I’m really interested in sharing my work with you.

Thank you in advance.

Yeah I liked the description (Stealth) problem, most of excel people I’ve met personally were stuck, and really embarrassed (blushed faces) from these excel (stealth) trouble issues in-front of their dealers, and even enforced me to spend several months resolving such issues from my proj one after the other, to be fully authentic (( Sealth Proof)) doesn’t let any mistake for users that might commit even if they don’t know what excel is. Yet still though made me suspicious about the efficiency of excel in general in building account-statements applications. Honestly by time I became really hectic about such troubles ends up in total crash, and imagine if transactions committed are not saved !

The proj is built on long experience and extensive testing by users for a very long time. I think after all it would be a powerful application.

★ I hope adopting this styling won’t cause any trouble. Especially the (Stealth) ones.

★ I wish you luck, wish me that too, I’ll be in touch
Thank you in advance @Jaafar Tribak
