• Visual C++ Trying to create a pointer array in a class

  Hi, I am trying to create a dynamic array with pointers in a class. Would the syntax be int* x, int* x[], int** x, or something else When I try to do it with int* x[] and I dont put it in the last line of the class, it will give me the error "error C2229: class 'Stack<T>' has an illegal zero-sized array" while if I put it in the last line it will give me the warning: " warning C4200: nonstandard extension used : zero-sized array in struct/union" When I increase the size of the array I do this, void Stack<T>::push(T X) { array[size++] = new T(X); } Whenever I run the program and the program exits, it gives me the runtime error "Run-Time Check Failure #2 - Stack around the variable 'test' was corrup ...Show All

• Visual C++ "Stack Overflow message"

  Hi, I was trying to write a simple hello world program using wxwidgets. The issue I faced was when using Visual studio 6.0 my application crashes by giving "Stack Overflow" message.

• Visual Studio Team System Need Help with Bug Rates Linked Report

  I am trying to make a linked report based on the "Bug Rates" report. I want to accept all current defaults except for Area Path. What is the proper format for the area path parameter I have explored the members of the Area measure using SQL Server Mgt Studio, but I can't seem to get the proper format. The default Area for the Bug Rates report is specified by the DefaultAreaParam query. In Report Designer you can view the query from the data tab. The value will be something like [Area].[Parent_ID].&[<Some ID>]. Take a look at the AreaParam and DefaultAreaParam queries and the AreaParam Report Parameter to see how these are used. ...Show All

• Internet Explorer Development IInputObject no longer called in IE7?

  Has the behavior around IInputObject changed for IE7 We're doing the standard: 1. On SetSite(), get the IID_IInputObjectSite from the IUnknown parameter. 2. When one of our UI Windows gets or looses focus, call IInputObjectSite::OnFocusChangeIS() It all appears to work; however, we never see callbacks on our IInputObject methods: UIActivateIO, HasFocusIO, TranslateAcceleratorIO. Well, that's not completely true. We see a callback on IInputObject:: UIActivateIO(FALSE..) when a second, different toolbar calls IInputObjectSite::OnFocusChangeIS(FALSE), but that's the only time (we see it in the stack crawl). Is this behavior different from IE6 This bandobject needs these calls to do it's UI correctly. It's more complex than a simple editbox ...Show All
