From the Home menu, select Go Back to travel back in time until the breakpoint is hit. From the View ribbon select Stack. To do this use the ba command using the address we want to monitor. Setting a breakpoint using the source window An alternative way to perform this investigation would be to set a breakpoint by clicking on any line of code.

Click on any of the occurrences to display more information about that occurrence of memory access. The stack shows that that Greeting! This portion of the walkthrough assumes that you are still located at the breakpoint from the previous section.

In the locals window, greeting is available in the current context, so we will be able to determine its memory location.

Memory 0xddf,0xddf, "rw" [5] EventType: Memory objects, see TTD.

Memory 0xddf,0xddf, "rw" [5]. For more information about the TTD. Use the dx command to look at the four bytes in memory starting at that address with the read write access.

As we look at the size issue further, we also notice that the message is 75 characters in length, 76 including the end of string character. For example, to set a breakpoint on the greeting variable in the GetCppConGreeting method, use this procedure.

From the View ribbon, select Watch and provide sizeof greeting. Once a trace is recorded, the trace and repro steps can be shared, and the issue will be reproducible on demand on any PC. The greeting array that we declared is 50 characters in length, while the sizeof greeting that we pass into GetCppConGreeting is 0x64, Determine the address of the DisplayGreeting!

As we are wondering about the size of the greeting string we will set a watch window to display the value of sizeof greeting.

On the Time Travel menu, use Time travel to start command to move to the start of the trace. This information supports the idea that the stack was corrupted. Memory objects to view memory access Another way to determine at what points in the trace memory has been accessed, is to use the TTD.

Memory 0x1bf7d0,0x1bf7d4, "rw" [0x0] [0x1] [0x2] [0x3] [0x4] [0x5] [0x6] [0x7] [0x8] [0x9] [0xa] Breakpoint 0 hit Time Travel Position: Last function to the end of the dx command. Because the function will just be read from memory for execution, we need to set a r - read breakpoint.

Set the breakpoint with the ba command using the memory address we want to monitor for write access.

In the locals window we can see that the destination variable has only part of the message, while the source has contains all of the text. Summary In this very small sample the issue could have been determined by looking at the few lines of code, but in larger programs the techniques presented here can be used to decrease the time necessary to locate an issue.

Use the breakpoints window to clear any existing breakpoint by right clicking on the existing breakpoint and selecting Remove. DetermineStringSize function using the dx command.

One way to fix the code would be to expand the size of the character array to We want to monitor writes for four bytes, so we specify w4.BIOS BIOS/ BIOS Week 4 iLab Carbohydrates Test | View Lab Report - from MICROBIO N at Chamberlain College of Nursing.
