Store and une a filename in a variable

Hi,
I'm trying to improve a small program I just finished and one point would be to handle BMP files via a variable (ImageFile$) instead of having to name each file every time.
The purpose of the program is to display the actual kind of dance played and the user can select them by directly clicking on each image's list (easy to understand - I wish I could attach some images).
Code:' Image Launcher short
NOMAINWIN
WindowWidth = 1920
WindowHeight = 1080
LOADBMP "BackgroundImage",".\Aucune.bmp"
GRAPHICBOX #MainWindow.GBx1,0,0,1920,1080
STYLEBITS #MainWindow.GBx1,0,_WS_BORDER,0,0
[MAIN]
OPEN "Display BMP image" FOR window_popup AS #MainWindow
#MainWindow "TRAPCLOSE [QUIT_MAIN_WINDOW]"
#MainWindow.GBx1 "down"
#MainWindow.GBx1 "drawbmp BackgroundImage 0 0"
#MainWindow.GBx1 "when leftButtonDown [MouseLeftButton]"
WAIT
[MAIN_REFRESH]
'***
LOADBMP "BackgroundImage",ImageFile$
'***
#MainWindow.GBx1 "down"
#MainWindow.GBx1 "drawbmp BackgroundImage 0 0"
WAIT
[QUIT_MAIN_WINDOW]
CLOSE #MainWindow
END
[MouseLeftButton]
IF (MouseX > 1685 AND MouseX < 1770) THEN 'Aucune
IF (MouseY > 1055 AND MouseY < 1069) THEN
UNLOADBMP "BackgroundImage"
'****
'LOADBMP "BackgroundImage",".\Aucune.bmp"
ImageFile$ = ".\Aucune.bmp"
'****
GOTO [MAIN_REFRESH]
END IF
END IF
IF (MouseX > 603 AND MouseX < 671) THEN 'Bachata
IF (MouseY > 962 AND MouseY < 979) THEN
UNLOADBMP "BackgroundImage"
'****
'LOADBMP "BackgroundImage",".\Bachata.bmp"
ImageFile$ = ".\Bachata.bmp"
'****
GOTO [MAIN_REFRESH]
END IF
END IF
IF (MouseX > 207 AND MouseX < 315) THEN 'Cha-Cha-Cha
IF (MouseY > 919 AND MouseY < 935) THEN
UNLOADBMP "BackgroundImage"
'****
'LOADBMP "BackgroundImage",".\Cha-Cha-Cha.bmp"
ImageFile$ = ".\Cha-Cha-Cha.bmp"
'****
GOTO [MAIN_REFRESH]
END IF
END IF
IF (MouseX > 1820 AND MouseY > 1045) THEN GOTO [QUIT_MAIN_WINDOW] ' "Quitter"
WAIT
The changes are between '*** .
NB: how do I attach a file to the thread?

What's the problem? Are you saying that this line from your program isn't working:
Code:LOADBMP "BackgroundImage",ImageFile$
Even the LBB docs show a variable being used for the filename, so it should certainly be OK.

You can't, as far as I know.

I had to do it this way:
Code:
...
[MAIN_REFRESH]
UNLOADBMP "BackgroundImage"
LOADBMP ".\" + ImageFile$ + ".bmp"
#MainWindow.GBx1 "down"
#MainWindow.GBx1 "drawbmp BackgroundImage 0 0"
WAIT
...
[MouseLeftButton]
IF (MouseX > 1685 AND MouseX < 1770) THEN 'Aucune
IF (MouseY > 1055 AND MouseY < 1069) THEN
ImageFile$ = "Aucune"
GOTO [MAIN_REFRESH]
END IF
END IF |

I'm not too sure what point you are making. The leading ".\" to the file specification doesn't achieve anything ('dot' is the current directory anyway); you would probably be better to use DefaultDir$ like this:
Code:LOADBMP "BackgroundImage", DefaultDir$ + "\" + ImageName$ + ".bmp"
