I believe you need to call pclose() on the descriptors returned from popen() in your CPUread() function. See the popen() documentation here: popen() man page on die.net I’m not sure this directly is the cause of your problem, but it is definitely a resource leak. 0 solved Memory leak with out malloc [closed]
The object is not destroyed, but the name obj isn’t available inside reg() – that’s just what you named your object inside main(). You can refer to the current object inside member functions via *this, but you can also access members directly. 2 solved Why can’t I refer to an instance of a class by … Read more
Try to use const when you’re passing in a pointer that will not be altered. You shouldn’t be passing as a pointer unless you plan to have the argument as NULL at some point. In this case we always want the vector to have at least one human. It’s a good idea to use std::vector … Read more
The problem wasn’t the c++ code itself, but the framework it used, in this case ROOT. If you define a pointer in a ROOT class, you have to tell the program what to do with that pointer in the case of the class being written to file. Even though the class might never be written … Read more
You can add separate properties in your ViewModel and separate ComboBoxes in the view, then manipulate the values when a value changes in the ViewModel, but this is cumbersome, and involves a lot of work when you add a new ComboBox (value). A better approach is to create a custom collection that handles the changes: … Read more
I found answer on my question. This happens when you merge typed dataset to another dataset and target dataset does not contais typed table. for example: var sourceDataSet = new SomeTypedDataset(); var strongTypedTable = new SomeTypedDataTable() sourceDataSet.Tables.Add(strongTypedTable ); var targetDataSet = new SomeTypedDataset(); targetDataSet.Merge(sourceDataSet);// at that step targetDataSet will contains strongTypedTable byt this DataTable is … Read more
Saw your question on my youtube video. It looks to me like some of your triangles are being culled out on the extended bar. Maybe some of the triangles on the bar have incorrect winding? Something to check for. Check the winding on the triangles and play around with the opengl cull face. as for … Read more
For example for this line: printf (“%d\n”, *(*(p + 1) + 1)); Look at that line: int *p[] = {*a, *(a + 1) , *(a + 2) }; So p is pointer (array) to integer pointers with some address and value *a at initial index. Then (p + 1) is next address of p and … Read more

Try this using LINQ in C# var result = from tab in dt.AsEnumerable() group tab by tab[“ApplicationNmae”] into groupDt select new { ApplicationNmae = groupDt.Key, Sum = groupDt.Sum((r) => decimal.Parse(r[“Count”].ToString())) }; DataTable dt1 = new DataTable(); dt1 = dt.Clone(); foreach (var item in result) { DataRow newRow = dt1.NewRow(); newRow[“ApplicationNmae”] = item.ApplicationNmae; newRow[“Count”] = item.Sum; … Read more
struct a s1={“Hyderabad”,”Bangalore”}; assigns “Hyderabad” to ch and “Bangalore” to str. printf(“\n%c%c”,s1.ch[0],*s1.str); prints the first character of the strings. Since ch is an array, ch[0] represents its first character. Since str is a character pointer, it points to the first character of a string here. So, *s1.str will have value ‘B’ printf(“\n%s%s”,s1.ch,s1.str); simply prints all … Read more

The problem is that you are taking sloppy English and translating it literally to create broken C++. When you say: the character is not ‘N’ or ‘n’ this, while commonplace, is wrong. For the same reason, your C++ code is wrong. You are comparing getche() to ‘N’ || ‘n’, an expression which applies boolean-OR to … Read more
