Why strings are shown partially in the Visual Stud

问题:

I'm debugging a C++ application with VS2008 and with some long select queries I'm not able to see the full text in the debugger. It just shows a part of the query.

Is there a way to see the full text?

Thanks in advance.

EDIT: The real query available at the string is:

select  c.cd_seq, m.diag_code, m.diag_descr, 'S' as source 
from custom_booking_data c 
left outer join meddiagnosis m 
on c.cd_number_value = convert( decimal( 28, 8 ), m.diag_urn ) 
where c.custom_data_urn = 4 and c.cd_field = 433 
union 
select  c.cd_seq, m.diag_code, m.diag_descr, 'H' as source 
from custom_booking_data c 
left outer join ordiagnosis m 
on c.cd_number_value = convert( decimal( 28, 8 ), m.diag_urn ) 
where c.custom_data_urn = 4 and c.cd_field = 594

Not that long if you ask me.

Hover the variable you want to view, then click on the magnifier icon following icon, or select the arrow right to the icon and select Text from the drop down menu

This is the result, i think you asked this...

This seems to be a 'feature' in Visual Studio. I see the same thing in VS2012 using C#, with a string that is just over 500 characters.

The solution that I found was to right click on the variable in the debugger and do a 'Quick Watch' on it. The string is not truncated in the Quick Watch window.

Could it be that your string contains NUL '\0' values? Textbox controls like the ones the debugger is using will interpret them as the end of the string.

This is in a comment but really is the answer I was looking for: File.WriteAllText(@"C:\Temp\temp.txt", str)

I think you can right-click the item and then 'copy to clipboard'. Then paste it into another text editor.
