string copy truncation

[rick7423]

Nice thought Ernst (), but this also fails to work. Truncates at exactly same place!!!!

_bstr_t sndSQL;
sndSQL =  ::SysAllocString(L"updatemachineData_h 'RKR ','020',83300,105081,'01-00300-0350',
'C400 CU BL 4928TW (VL)   ',
7.987000,7.987000,7.900000,7968,749272,2.185000,100.000000,100.964066,
1.439381,2.660000,'03000 '");

What could be configured to PREVENT this from copying correctly? There must be soemthing preventing this from working.

How are you verifing the data in the _bstr_t? By outputing it via code? Have you looked at in the memory window?

If you are using the debugger to verify the contents of the string via the watch/quick watch windows then that is your problem. If that is the case what is your version of the IDE you are using? 6.0 [has issues with unicode strings being displayed].

actually, yes via the watch window!!! And yes, I am using version 6.

let me dump it to a text file and see what that says...


GAAAAK!!!
The test log shows the entire string!!! It was the debug watch window AND the mouse over watch function that was truncating it.

Wow, my bad!!!

Thansk for all your help, sorry for the false alarm. I guess you learn something new everyday.

Yea. Well the limitation is more pronounced with UNICODE strings. I believe the display truncation length is around 252 or so.

You can probably find visual studio add-ins for VC6.0 that will allow you to do quick-watches on longer strings via google.
