Problem with a Structure

[BeeTrap]

Don't know if anyone needs to see this, but, I just tried to run my encryption program under the 347 Alpha and get an error.  The code runs under ver 4.5.1 Pro without any problem.  What I see is the second dot/period in each line is shown in red with a black underline.  The thing is, only the 1st, 3rd, 4th and 5th lines are highlighted like this.  I get

       "Syntax error: at line 399: BrowseInfo.plszTitle$.struct = Hint$

I thought that it may have been the extra spaces before the "=" sign, but the next line
      "BrowseInfo.pIDLRoot.struct = GetSpecialfolderIDL(hexdec(RootDirID$))"

does not show the second period/dot as red and underlined in black.

Below is from the "Updated" Sample Code that Rod supplied around August 2017..........  this is from "browseForFolder.bas".

'-- There are many discussions on conforums that include browse for folder code

'---- Older versions give an occasional protection violation error

I'm pretty certain Carl has said that LB5 alpha 347 is not API capable. I'm also sure we will have that functionality in time.

Rod is correct, Carl has mentioned that LB5 is not ready for API interfacing yet and that's what Structures are mainly used for in LB.

The reason you are getting the underline and red period is the syntax checking is flagging the "$" it seems. Remove the "$" from your struct names and references and the syntax checker seems to be OK with it. It still does not compile though....because it isn't supported yet.

I stopped using the "$" for my ptr struct members long ago because it broke the syntax highlighting in LB4, and the "$" is not actually required for a ptr struct member.

Thanks guys and, sorry about that! I did read what Mr. Gundel had said about APIs, but I didn't stop to think what that included.

[Brandon Parker]

No problem.....

Early Alpha's tend to have quite a bit of stuff missing.
