adding componet fail

[harald]

hi !

I tried to add the inthehand.windowsmobile.dll (In The Hand) as component but i crash
on the device after adding and on the desktop they not appear in the add objects menue.

when i use the dll in a vs2008 or vs2005 project i have no problems.

when i use my own dll's i also have no problems with basic4ppc

is there a restriction on dll usage ?

thank you in advance,
harald

Not all dlls are supported out of the box. You will need to create a wrapper above this dll.
See this thread for more information about libraries: http://www.b4x.com/forum/code-samples-tips/35-how-create-basic4ppc-library.html

The rules for a dll to be usable by Basic4ppc are roughly

1) All parameters and returns of methods and properties must be primitive types or arrays of primitive types.

2) Classes used as Basic4ppc objects should not be nested in other classes.

3) If the library wants to raise Basic4ppc events it needs to conform to the Basic4ppc event converntion.

4) You can hide Classes or Structs that you don't want visible within Basic4ppc by prepending the name with an underscore.

Object is also supported and is very useful in many cases.
