[ad_1] I have done similar work in C# earlier, I use HTMLAgilityPack for doing this kind of works. Later I start using Anglesharp since it has a very good CSS selector based support. Try anglesharp and you can modify the HTML tag like you do in jQuery. 1 [ad_2] solved Change text in HTML that … Read more
[ad_1] One way would be to have a function returning a reference to a static instance: const std::vector<int>& get_magic_vector() { static std::vector<int> v{3, 5, 1}; return v; } Then for (auto i : get_magic_vector()) std::cout << i << ” “; 2 [ad_2] solved c++ define vector in separate function
[ad_1] You should debug your code by yourself. void stack::push(int *dat) { ch::LinkList* newNode = new ch::LinkList; newNode->initialize(dat,ptr); ptr->head = newNode; } void stack::ch::LinkList::initialize(int *dat, ch *nxt){ data = dat; if(nxt->head) next = nxt->head; else next = 0; } Note that: ptr is nullptr,so nxt is a nullptr too. So you crash… make ptr not … Read more
[ad_1] Try this: int oddCount = 0; int evenCount = 0; int oddSum = 0; int evenSum = 0; int in; do { std::cout << “Type in a number:”; std::cin >> in; if (0 == in) break; if ( in % 2 == 0 ) { evenCount++; evenSum += in; } else { oddCount++; oddSum … Read more
[ad_1] You’ll want to use the sys.databases table for that probably; SELECT name FROM sys.databases 5 [ad_2] solved How to display a list of the database? [closed]
[ad_1] SaveChanges in Entity Framework causes error Validation failed for one or more entities. See ‘EntityValidationErrors’ [ad_2] solved SaveChanges in Entity Framework causes error Validation failed for one or more entities. See ‘EntityValidationErrors’
[ad_1] (form the comments) Remove tid2= tid2 + teach[i].IDnum;. Yes, you can use if (tid == teach[i].IDnum) However, look at what your while(1) loop in tborrow is doing: while(1) read a teacher from the file is the teacher the right one? yes – do something no – print an error and recursively call tborrow again. … Read more
[ad_1] For doing that, you have to remember in which order you are running (reverse or not). So you will have a variable indicating if the order is reverse or not, and change it when you reach the extremities of your counter (0 and 3) And you can optimize the code with using 1 and … Read more
[ad_1] There is a standard function called std::find in the header <algorithm>: #include <iostream> #include <algorithm> int main() { int myarray[6]{10, 4, 14, 84, 1, 3}; if (std::find(std::begin(myarray), std::end(myarray), 1) != std::end(myarray)) std::cout << “It exists”; else std::cout << “It does not exist”; return 0; } Ideone [ad_2] solved Find if an element exists in … Read more
[ad_1] You’ve forgot to state the correct question. As I can see from the Java code provided (reverse engineering), all you want is to have MD5 hash code (as a String) for a given file; if it’s your case, you want just to Create MD5 crypto Open the file Compute hash on file stream Represent … Read more
[ad_1] you can always declare if something is a struct even if you have declared it before. it doesnt make a difference in the output of the program. 5 [ad_2] solved Is this stucture an array of structs? [closed]
[ad_1] It are functions, you have to call them as such. Note the brackets () cout << “Printing circle ” << this->getXYr() << endl; cout << “Circle Area: ” << this->circArea() << endl; cout << “Circle Perimeter: ” << this->circPeri() << endl; this-> is not explicitly needed. Your second error is due this->getXYr() does not … Read more

[ad_1] There is no general problem with two threads executing system calls on the same socket. You may encounter some specific issues, though: If you call recvfrom() in both threads (one waiting for the PLC to send a request, and the other waiting for the PLC to respond to a command from the server), you … Read more
[ad_1] printf is unusual in that it has no single function signature. In other words, there’s no mechanism to automatically take the actual arguments you pass and convert them into the type that’s expected. Whatever you try to pass, gets passed. If the type you pass does not match the type expected by the corresponding … Read more
