oei->obje_GetInfo (&mi);
strncpy(mi.String1,komutlar[id].komut_data,30);
strcpy(mi.String2,"ddd"); //this line crash
}
}

i can change String1 but cant change String2
why?

please help.

(sory for bad english)

What's the reason for the crash?
Is String2 Correctly filled before? (debug with an entity, which has a filled string2)
Is it a null pointer?

Please give more information about the error-message.

WED
---------------------------
Crash in 'C:\Program Files (x86)\GStudio7\wed_plugins\si_AyarYukleyici.dll'
---------------------------
OK
---------------------------

this is err message.



i think String2 pointer has no memory area.
but if i alloc memory for String2,
in this case code runs but notting changed
its mean String2 not change.

thankyou for your time.

hmm did you try to allocate the memory for String2 like this :

mi.String2 = malloc(sizeof(char) * 31);

and not

mi.String2= new char[31];

? maybe the program internally tries to change the string2 and thus tries to deallocate the string2, but not using delete, but free !

edit: i just saw that you already have no crash, so this post won't be useful

what happens if the entity already have set up a string2 in wed?

TechMuc, i respect you.

i check my test scene and i see that, all entitty's String1 have a value,
but String2s not.

if i manualy set all entitys String2,
plugin correctly run.

thank you for suggestion.

but its not solve for me.
my code must run all case,
if String2 is not set, plugin must set a value.

i think problem is allocation.

how i alloc memory to StringX and wed accept that.
because wed not accept that: (mi.String2= new char[31]

thank you for your interest.

you have already been given suggestions:

mi.String2 = malloc(sizeof(char) * 31);

Quadraxas read Stromausfalls post carefully

oh right no crash...

i had several plugins, never actually worked with string2, but if you can send me a stripped down version of your project i could make expirements.

i cant send project to you sory.

problem is not only string2
if string1 is empty in this case this line crash
strncpy(mi.String1,komutlar[id].komut_data,30);

its mean i think string1 or string2 not important
if editbox is empty you cant transfer data to string area.
