I am pretty new to vb.net and as such facing a pretty simple.
I have an application which is finally going to call a function defined in a dll.
The function declares a variable of type unsigned long
int funct(unsigned long lvar);
The size of unsigned long on my machine in 4 bytes.
Now in vb.net (I am using VS 2005 express) app, I have declared a variable(lvar) of type int32.
In the vb.net app, I am giving the variable (lvar) a value equal to "He443ea12"
(decimal value = 3829656082 )
This value is greater than the max value of the type int32.( max value = 2,147,483,647)
After this I am calling the function funct(lvar), defined in the dll, in the usual way.
Everything is working fine with the function doing it's intended purpose.
However, I read in some article that vb.net raises an exception as soon as it detects the
integer getting overflowed. In my app, integer overflow is clearly taking place ,but still I
am not getting any exception from my app.
Can somebody please point out where I am wrong?
PS I cannot use uint32 in my app so as to make the app CLS compliant. Also I cannot use Int64 as
the variable in my dll is of 4 bytes and hence it's usage is giving me the stack
