How do I examine contents of stl vector when debugging?
Author
When I try to look at an STL vector in the watch window in Visual Studio 2003, I can only look at the first element. For instance,
NAME VALUE
- m_tickRate {first=??? last=???}
- std::_Vector_val<long,std::allocator<long> > {_Alval={...} }
- _Alval {...}
- std::_Allocator_base<long> {...}
- _Myfirst 0x0104b350
- 7
- _Mylast 0x0104b368
- -33686019
- _Myend 0x0104b368
- -33686019
Trying to evaluate m_tickRate.at(0) gives me "CXX0039: Error: symbol is ambiguous". Evaluating m_tickRate[0] gives me "CXX0058: Error: overloaded operator not found".
Is there a clever way to examine the contents of a vector, short of copying the contents to a normal C array? I tried various castings to resolve the ambiguity error, to no avail.
There is an addon available at SourceForge which might help you out - I think it was actually written by one of the guys here on GDNet. It's not been updated in a little while, but should still do what you want. It's called VSEDebug.
Hope that helps.

You cant just code a function to for loop through the vector and dump its contents to the console?
You can copy it temporarily to an array if you want to examine it
int *t = &myVector[0];
since all the data in a vector is arranged as an array in memory.
EDIT: ok that's better than my solution :)
int *t = &myVector[0];

Not exactly sure with VS2k3, but with Eclipse atop MinGW, I can do:
#include <vector> #include <iostream> int main () { std::vector< int > ints; ints.push_back( 1 ); ints.push_back( 2 ); ints.push_back( 3 );o //breakpoint here std::cout << std::endl; //we dont want to reach the end of the function yet }______________| Variables |_________________________________...| - [#] ints| - [#] _Vector_base<int,std::allocator<int> >| - [#] public| - [#] _M_impl| + [#] allocator<int>| - [#] public| + [o>] _M_start = 0x003d2588| + [o>] _M_finish = 0x003d2594| + [o>] _M_end_of_storage = 0x003d2598...Then right click "_M_start", select "Display As Array...", enter in the starting index (0) and length (3 in this case - if you don't know this, do (_M_start - _M_finish) / sizeof( type ) ). Then:
______________| Variables |_________________________________...| - [/] ints| - [/] _Vector_base<int,std::allocator<int> >| - [/] public| - [/] _M_impl| + [/] allocator<int>| - [/] public| - [/] _M_start| | |- [/ _M_start[0] = 1| | |- [/ _M_start[1] = 2| | \- [/ _M_start[2] = 3| + [o>] _M_finish = 0x003d2594| + [o>] _M_end_of_storage = 0x003d2598...Quote:Original post by goldenpanda
Wow thanks for typing that up. What did you do to get the courier font?
Bored programmer ASCII art ftw!! :D.
