I get tired of typing "@strdel(@winexists(#MyWin),1,1)" every time I want
to use my window with an API. Could @winexists() just return the handle
without the percent (%) sign? Smile

I think
Me.hwnd
Me.hdc like VB would be nice.

there a some other things too that need to be added to make calling Non VDS dlls and API easier.

Also the way bitmap element is drawn You cannot get its DC - device context. So many things related to that is not possible.
Also it seems that cursors/bitmaps from resources cannot be loaded into memory using API for unkown reasons. Hiword/loword/hibit/lobit. Some more I cannot remember right now. I think these need be added.

hi ff,

why don't you use the CODE TEMPLATE section of vds which you can access from the ide using ctrl+J...very handy utility!

Oops, I forgot about that Serge Very Happy

I will try that. But still it would be nice
to just have @winexists() return it without the % sign, and have an optional
parameter to have it return with the % sign. Most advanced programming
is done with handles that don't have the percent sign. Smile

The reason for this is VDS variables are all one type. You can call the window functions with a window title, a class or a handle as the argument. VDS needs the % to know that the number that follows is a handle, and a # to know that what follows is a class. Everything else is treated as a title.

It's fine, but couldn't some output processing take place to fix this? Smile

I'm not sure what you mean by fixing it. It's not a bug, Julian explained why the % is required. When you use several vds functions that require an external window to be defined you can either pass a Title, Class or a Handle, to distinguish between the three you use a % for handles and # for window classes, anything else is considered a title.

No I don't think it's a bug, but I mean could the output be processed for
the return value? Perhaps I am misunderstanding something. This is
a function for the developer, not VDS itself. I am confused now.

So you want to have some kind of parameter like A(PI) next to the ones who already exist ? Smile

Example:
@winexists(#MyWin,A)

I think what needs to be borne in mind here is that making API calls is something only a minority of people will do. For VDS internal window functions, what it does makes sense. It doesn't make sense to complicate VDS functions for everyone just to save a line of code for people using APIs. You could write a VDS function to return the window handle in API format, and then call that every time instead of the standard one...

I don't think we are trying to be close-minded but isn't this a very simple thing to achieve with currently. I could understand if it took a few lines of code but it's really simple as it is now:

OK Please forgive me, I just feel that I'm just being told that it will never
happen. I really don't think it's a majorly needed feature. Sorry Jules and
PGWARE for saying people were closed-minded I was just feeling kind of
bad about this whole thing.
