Re: [twsocket] TWSocket - send bytes - strange chars

2006-05-24 Thread Wilfried Mestdagh 
Hello Werner,

I'm pretty sure this is a Java problem. Something to do with the 16 bit
char conversion. If you try text with char = 127 then do you have same
problem too ?

 Hi everyone,

 I have a spooky situation.
 I send a file.txt. This file contans some default chars as any file can have.
 This file is sended with the proc below to a java application.
 This java application will block reading until it has read all chars.
 Now the problem is, that the java will get some stack errors, only
 when certain chars are sended in this file.txt
 ( and i realy don't know wich chars, but a test, leaving some chars
 out of the file, point in that direction, the size is not imported) 
 I know this looks more like a java problem, but maybe somebody has 
 encountered something simular.
 So my question is : are their any chars or combination, that could
 be sensitive ? This question is as wierd then the problem I have :).

 Thanks for any idees
 Greetings

Thanks Wilfried to point me on this possibility, hoped this would be it.
I tried only sending bytes  31 and  127 but it remains the same.

Rgds,
Werner
