Doors Access violation

Bonjour,

En exécutant un script DXL je suis tombé là dedans:

Je pense que la source du problème c'est que j'instanciais un Array, et que je mettais dedans des éléments n'étant pas tous du même type (notamment j'avais des int dans une colonne et des string dans une autre colonne).

You need to be very careful with the type of data that you put in Skip lists and Arrays. If you put in one type (e.g. int) and read out another type (e.g. string) you almost always will get an exception. The exception log is normally only useful for IBM programmers. So what can we do for you? If you want to find & fix the error you should post the relevant parts of the code. Regards, Mathias

That exception info isn't very useful, but the displayed DXL errors are since it tells you which line of code and sometimes what the problem might be.

Hi,

I have found a work-around using two one-dimensional arrays.

I think I have written and read the same type, but one thing was that the Array did not have the same type on each element.

Here is a minimal example:
Array toto = create(1,2);

put(toto,"salut",0,0);
put(toto,666,0,1);

int x;
string y;

y = get(toto,0,0);
x = get(toto,0,1);

(0,0) is a string, (0,1) is an integer, writing and reading are consistent with that, but there is an access violation.

Well, that's fine: the only problem is that the documentation does not warns that all elements have to be of the same type.

Vincent.

The elements do not have to be of the same type, you just have to know the type and do a cast to the correct type, so your example can be re-done as
  

Array toto = create(1,2);
 
put(toto,"salut",0,0);
put(toto,666,0,1);
 
int x;
string y;
 
y = (string get(toto,0,0))
x = (int get(toto,0,1))
 
print y " " x ""

 


The DXL Help has this advice: "Returns the data, of any type, stored in array a at position (x, y). You must retrieve the data into a variable of the same type as used when the data was put into the array. To ensure that this works unambiguously in the way intended, you should use a cast prefix to the get command."
