Hi Marc,
This is a new feature of version 19. I just started to use it a few times.
Best regards,

Did not know we have this construct in WinDev. I use WITH all the time in Visual Foxpro. When you need to do many things, I have always assumed this was more efficient since you only have to evaluate the root element once. Now that I know it is there, I will be using it.

Hi all
Please correct me if I am wrong, but I understand that, for instance:
Product.ProdNo = 123
Product.ProdName = "Screw"
is equal to
With Product
.ProdNo = 123
.ProdName = "Screw"
END
so what is the big deal?
What are the benefits and drawbacks of the With - End structure?
I see one big con: when doing a global search for any Product file's items, I would not find them in the With - End structures.
What are the pros?
Best regards

HI Ola,
The Pros are that you have less typing and with your global search you would find the with structure where the file is used and I would not see that as a CON.
Cheers,

Hi Ola,
We do a lot of OOP. The gains are big in some use case.
pclMainModel.m_tabItems.m_sName = ""
pclMainModel.m_tabItems.m_sDescription = ""
pclMainModel.m_tabItems.m_sOption = ""
Other solution:
// Shorten in using a pointer to the item (and is thread safe, sort-safe, for the array)
pclItem is a CItem dynamic = pclMainModel.m_tabItems
pclItem.m_sName = ""
pclItem.m_sDescription = ""
pclItem.m_sOption = ""
Other solution:
// Shorten in using WITH
WITH pclMainModel.m_tabItems
.m_sName = ""
.m_sDescription = ""
.m_sOption = ""
END
Other solution:
// Shorten in using pointer and WITH (necessary in some cases to be thread safe, sort-safe, with the array)
pclItem is a CItem dynamic = pclMainModel.m_tabItems
WITH pclItem
.m_sName = ""
.m_sDescription = ""
.m_sOption = ""
END
Etc.
Some other use case are when you have a lot of members to work with at the same time. You save, again, a lot of coding. (This example has only 3 members. I use it when it is obviously a gain of time.)
Best regards,
