loading a bmp into a graphics box

[Larry]

I am trying to load a bmp into a graphics box.  I have a project file that is loaded which contains all of the names of the files associated with the specific language that will be edited using my Dalota language editor and dictionary program. Then, one at a time those are loaded into the system. Depending on the language being edited, as to what those filenames will be, therefore the variable script$ holds the filename of the bmp to be displayed.

I've tried it this way, but it would appear that possibly the loadbmp command cannot take the variable script$, in place of the actual filename enclosed in quotes. Any help would be appreciated.

[lists.b12]
print #lists.gb1,"show"
print #lists.tb1,"!hide"
loadbmp "script",script$
unloadbmp "script"
print #lists.gb1, "drawbmp script x y"
wait

well first off have you issued a down command? Secondly why unload before you have even used it? Also where do you fill script$?

Aldo what happens when you replace script$ with the literal drive,path and file name?

Try this.
Plug right path.
nomainwin
graphicbox #lists.gb1, 1,1,300,300
open "test" for window as #lists
#lists "trapclose [quit]"
#lists.gb1 "down"

script$ = "C:\progs\Just BASIC v1.01\bmp\CHERRY.BMP"

loadbmp "script",script$
'unloadbmp "script" 'unload it only in the end
x=50
y=100
'print #lists.gb1, "drawbmp script x y"
print #lists.gb1, "drawbmp script ";x;" "; y
wait

[quit]
unloadbmp "script" 'unload it here, the end
close #lists
end

Ninja'd by tsh!

Just a comment that the 'print' is redundant... see below
open "Test" for graphics_nsb as #wg

script$ ="test.bmp"

loadbmp "script", script$
#wg "drawbmp script x y"
unloadbmp "script"

wait

No I forgot the down command.

I have a data file, that has the filename in it that is to be loaded using loadbmp. I load it into script$ from the data file. Then I tried to draw it to a graphic box using drawbmp script$. When it did not work, I got a giant box with an error that all manner of wierd ascii type characters on it and I click ok and it goes away.

So we are still not fixed? If so print the the contents of sctipt$ tell us what it contains and give us a bit more detail on what the error report says.

I took your advice and I coded this line script$="f:\dalota\language script.bmp" and it works fine. This is a screen grab of the error lb4.04 pro gave when I did it the other way/lb4.04%20Pro%20error.jpg?dl=0

The problem is, I needed to be able to load any bmp I wanted in that graphicbox depending on the language file being edited.

I see two possible culprits
* file path
- make it print always, so you can see if it is formed correctly
* or file itself (LB is known? not to handle some BMP versions - I had troubles with less-then 256 color BMP saved from Gimp)
- if you know file what fail, will it fail if you hard code it?

[Rod]

why is there a .jpg involved? Liberty needs API help to load them directly.

I solved the problem. Thanks for all of your help Rod. It is much appreciated. The solution I cam up with is this.

[lists.b12]
print #lists.gb1,"show"
print #lists.tb1,"!hide"
notice "Please click on the bmp image that has the name of your language in it."
if script$="" then filedialog "Open language script picture", "*.bmp", script$
if script$="" then wait
loadbmp "script",script$
print #lists.gb1, "drawbmp script 5 5"
unloadbmp "script"
wait

It is  odd however as I see no difference between loading the filename in from a data file versus this way, but it works so I am not complaining

Thanks for your help. I do know sometimes file formats can be tricky. No, it did not fail when hardcoded. However, I had to find a way to make it dynamic and not static. I needed to be able to load a different bmp, depending on the name in the data file, which turned out not to work. I finally had to have the user ( namely me), select the bmp file from a fialdialog in order to get it to work right.

There isn't. I'm not sure what happened there. It was always a bmp. The screen grab I made of the error in lb4.04 Pro might have been a jpg
