Variable Number Of Rows Of Texboxes

Richard
I have followed your advice in using MAPHANDLE. Because I had varying column widths in my table I had to set up 5 sets of FOR...NEXT loops to deal with it, but it appears to work. My next problem was that I didn't want a gap to appear between the table and any following controls. I used some of my old code to resolve that.
My next problem is that I need to scroll the window because it is not big enough to hold all of the controls. Alyce Watson directed me (in LB Conforums) to some MIDI API code. I've not yet come to terms with the Windows API (must do!) and I couldn't get it to work. I'm trying to sort that, but maybe you might have further ideas. The code I've written to date is shown below:
Code:
' SIMPLE BEAM ANALYSIS
' Using LB Booster - 1 April 2015
' Table based on code provided by Richard Russell
' The code currently leaves a big space above the table,
' but this will be filled by other controls, etc, in
' due course.
' This code removes the problem of the texteditor position
' remaining fixed when the number of rows in the table is
' reduced, so eliminating an increasing gap between table
' and text editor.
' Unfortunately, this code only works with LBB, not with LB.
' The next problem to solve is how to scroll the window,
' because the text editor and any following controls will not
' fit thw window size.
' Alyce Watson kindly pointed out a solution using a MIDI API
' but whilst it worked for the example she pointed to, with
' my lack of knowledge of the Windows API, I was unable to get
' it to work. BUT I'm working on it!!!

I don't think you did. How about this as an alternative:
Code:for row = 1 to NumOfRows
for col = 1 to 9
TextboxColor$ = "white"
select case col
'First column (Load Reference)
case 1: xpos = 10 : width = 65
TextboxColor$ = "cyan"
'Second Column (Description)
case 2: xpos = 75 : width = 380
'Columns 3 to 8
case 3,4,5,6,7,8: xpos = col*65+(455-65*3) : width = 65
' Column 9 (Total Loads)
case 9: xpos = (10+65+380)+(col-3)*65 : width = 75
end select
if col < 5 then
stylebits #m.tb, _ES_CENTER, _WS_BORDER, 0, 0
else
stylebits #m.tb, _ES_RIGHT, _WS_BORDER, 0, 0
end if
textbox #m.tb, xpos, TopOfTable + row*20, width, 20
maphandle #m.tb, "#m.tb";row;col
next col
next row

Scrolling Windows controls is rather uncommon, and as far as I'm aware the only 'official' solution is to use a Pager Control:
https://msdn.microsoft.com/en-us/library/windows/desktop/bb760855.aspx
I've not tried doing that myself. The use of an MDI window as suggested by Alyce is interesting; I don't know whether that usage is supported by Microsoft and therefore how reliable it might or might not be. I'd be inclined to try the Pager Control first.

Not sure I completely understand what you need but maybe you can modify this as needed. It uses API created textboxes in a graphics window that can be scrolled. In the program where I use this I also have it set to scroll with the mouse wheel via the WMliberty dll.
Code: nomainwin
WindowWidth=500:WindowHeight=440
UpperLeftX=int((DisplayWidth-WindowWidth)/2)
UpperLeftY=int((DisplayHeight-WindowHeight)/2)
graphicbox #grid.gb, 5, 25, 453, 290
button #grid.continue, "Get Contents Textbox 5", [ContinueSettings], UL, 10, 360, 150, 25
button #grid.close, "close", [close], UL, 230, 360, 70, 25
stylebits #grid.gb, 0, 0, _WS_EX_CONTROLPARENT, 0
open "Grid" for dialog_modal as #grid
#grid, "trapclose [close]"
hWnd=hwnd(#grid)
#grid.gb, "fill white"
NumSettings=30
graphicheight=290
scrollrange=abs((NumSettings*22)-graphicheight+4)
#grid.gb, "vertscrollbar on 0 ";scrollrange
'create grid
fontheight=16
facename$ = "Arial"
FontHandle=CreateFont(fontheight,facename$)
gbh=hwnd(#grid.gb)

That code doesn't work in LBB (it doesn't scroll) so unless it can be modified to do so it would perhaps be better to post it at the LB forum. In fact I have no idea how or why it scrolls in LB (even though it does); can you explain?
I also have the same question for you as I do for the OP: couldn't you use a standard List View (Report Style) control instead?

I checked to see if it ran in LBB but must not have checked if it scrolled. I must have assumed it would. I just tried adding in the WMLiberty calls to see if it would scroll with the mouse wheel but it still doesn't work.

Not really, it is just something I tried and it seemed to work for my needs.

I probably could but at the time this was written (about 8 years ago) I wasn't as familiar with all of the different types and styles of controls that Windows has to offer.

The graphics window seems to be behaving as a kind of container control, a bit like the Pager Control I referenced in my reply to the OP. Why a LB graphics window would behave that way I have no idea; LBB's certainly doesn't - I wouldn't even know how to achieve it!
Your solution may well be suitable for the OP, all things considered, but he will have to revert to using LB 4.04 to take advantage of it.

One reason why a List View might not be suitable is that it's used for display rather than for entry (the fields are read-only). I don't know whether that is an issue for the OP.
It's a pity Win32 doesn't offer a general purpose grid control, of the kind one might want for a spreadsheet (.NET does, but that's not usable from LB/LBB). There are third-party offerings but I haven't tried any of those.

Thanks for your solution, but I really need the whole window to scroll. Below is a solution based on a recommendation by Alyce Watson (http://lbpe.wikispaces.com/MDIScroll).
My intention is to develop a program to calculate bending moments and shear forces for a simply supported beam. This can then be further developed to produced code to design steel, timber and reinforced concrete beams. The code that I have produced only provides the table into which data will be entered by the user. This will then be used to calculate bending moments and shear forces at points along the beam and be presented in tabular form in a texteditor control (or some other method) below the table. This is why I need the whole window to be scrolled, rather than just the table.
Richard, am I right to develop the code in this section or would you prefer it elsewhere?
Code:
' SIMPLE BEAM ANALYSIS
' Using LB Booster - 3 April 2015
' Table based on code provided by Richard Russell
' The code currently leaves a big space above the table,
' but this will be filled by other controls, etc, in
' due course.
' Unfortunately, this code only works with LBB, not with LB.
' The next problem to solve is how to scroll the window,
' because the text editor and any following controls will not
' fit thw window size.
' Alyce Watson kindly pointed out a solution using a MIDI API
' The code below includes a scrolling solution based on the
' method suggested by Alyce Watson. This involves utilising
' a child window and can be found at:
' http://lbpe.wikispaces.com/MDIScroll
'-------------------------------------------------------------
' Enter the number of loads to be supported by the beam.
' At the moment no checks are made for controling the number
' to 8 or ensuring that only numeric characters are entered.
input "Number of loads on the beam (1 to 8): "; NumOfRows
' number greater than 8 can be entered, but 8 loads is
' usually plenty for a simple beam

An issue with that solution is that the scrolling doesn't happen 'continuously' (although I don't know why not): when you drag the scroll box nothing happens until you release the mouse button - which means you don't know how far to scroll other than by trial-and-error. 
I made a number of 'incidental' corrections to your code which you might want to incorporate in your version. For example in your code the header fields are editable by the user, which presumably isn't intentional.

I agree, it's not ideal, but not that important. The user will get used to the page and take that into account when scrolling with the thumb. Alternatively, finer scrolling can be done with the scroll buttons at top and bottom.
You mentioned that you had noticed that the table header descriptions can be changed by the user. Not a good idea. You didn't say how to prevent it, but I found a STYLEBITS that could deal with it _ES_READONLY. I changed the appropriate line of code to:
stylebits #m.top, _ES_CENTER OR _ES_READONLY, _WS_BORDER, 0, 0
OR
stylebits #m.top, _ES_LEFT OR _ES_READONLY, _WS_BORDER, 0, 0

Yes I did: I said I had made the modification (and others) in my version of the program; you need only have looked there.
Ideally you should also remove the WS_TABSTOP style bit because despite being read-only the header fields are still included in the tab order, which isn't particularly useful.
Anyway I said I wouldn't be contributing to this forum any more, so I'll retreat to my comfort zone again.

Sorry, I didn't realise that you could alter earlier posted code insitu.
I'll look at your code.
I appreciate that you said you wouldn't be posting to this forum again, but I think I probably speak for all users and readers when I ask you to continue. Your experience and expertise is absolutely invaluable to us all.

I had a quick look at your code when you first posted it and decided it wouldn't easily serve my purpose. However, I've just looked at it again today and I can see some very useful code there, which I will probably be able to make use of in the future. So thank you very much for your post.
