Visual Studio C++ watch list for global arrays

Question

0.00/5 (No votes)

See more:

Global arrays do not display properly in a simple forms project. I can set local variables equal to elements of the global array and the values are correct. Scalar variables display properly.

Any ideas? I am using Visual Studio 2010.

C++

//GlobalTest.cpp : main project file.

#include "stdafx.h"
#include "Form1.h"

using namespace GlobalTest;

double XX[7] = { 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0};
double ZZ = 3;

[STAThreadAttribute]
int main(array<System::String ^> ^args)
{

    double YY[7];

    for(int i=0; i<7; i++)
    {
        YY[i] = XX[i];
    }

    // Enabling Windows XP visual effects before any controls are created
    Application::EnableVisualStyles();
    Application::SetCompatibleTextRenderingDefault(false);

    // Create the main window and run it
    Application::Run(gcnew Form1());
    return 0;
}

Use PRE tags to format code part, it makes the question readable.

Maybe if you showed the code that does the actual display of the data someone could offer a suggestion.

It is the debugger Watch List that does not display the proper values. The original program was a default Windows Forms solution generated by VS2010. Put a breakpoint at Application::EnableVisualStyles(); And you will see that YY and the scalar ZZ are correct and XX is not. If the declaration for XX is placed within main() all XX has the right values but is not Global.

- XX {Length=7} double[]
[0] 5.8837896832001251e-299 double
[1] 5.8841360114961856e-299 double
[2] 5.8843365173517701e-299 double
[3] 5.8845917066224970e-299 double
[4] 1.6698053231989028e-316 double
[5] 0.00000000000000000 double
[6] 0.00000000000000000 double
ZZ 3.0000000000000000 double
- YY {Length=7} double[]
[0] 0.00000000000000000 double
[1] 1.0000000000000000 double
[2] 2.0000000000000000 double
[3] 3.0000000000000000 double
[4] 4.0000000000000000 double
[5] 5.0000000000000000 double
[6] 6.0000000000000000 double

I tried the declaring the following code prior to main() and got even worse results in the Watch List.

typedef struct {
char Buf[6];
short dim2;
short dim1;
} bufferQ;

bufferQ bufferW[] = {
{"ABCD",1,2},
{"abcd",3,4},
{"EFGH",5,6},
{"efgh",7,8},
{"IJKL",9,19} };

Never had this problem. Are you sure that you do not have a memory error somewhere else in your program? I once took over a program that was written so poorly that the program would break if you changed variable names due to extensive memory errors.
