Assign integer to this->Tag property.

[PacR]

https://msdn.microsoft.com/en-us/library/system.windows.forms.control.tag(v=vs.110).aspx

This website is saying that only text can be assigned to tag property.

Can i somehow change the datatype to integer instead of text?

Because i get 'error C2676' when i try this code:

this->Tag = this->Tag + 1;

error C2676: binary '+' : 'System::Object ^' does not define this operator or a conversion to a type acceptable to the predefined opera

You cannot change Tag to integer. However you may inherite from System::Object and add an integer member:

this->Tag = gcnew IntObj(...);

...

(IntObj^)(this->Tag)->Value += 1;

Witch way is better ?

this->Tag = gcnew IntObj(...);

...

(IntObj^)(this->Tag)->Value += 1;

OR


Convert::ToInt64(this->Tag) + 1;

[coder777]

The second one converts the value only. You cannot assign a value.

If you want to use Int64 you can directly use it:

this->Tag = gcnew Int64(...);

...

*((Int64^)(this->Tag)) += 1; // This should work / Not sure about that though

I will have to write this->Tag = gcnew Int64(...); for every control i use.
for exapmple:

button->Tag = gcnew Int64(...);
button1->Tag = gcnew Int64(...);
label->Tag = gcnew Int64(...);
........

I could assign like this:

this->Tag = Convert::ToInt64(this->Tag) + 1;

Any other ways around?
