[ad_1] There is probably not a significant performance gain in using a C/C++ dll. The C# runs in an environment with a quite efficient JIT compiler, so my guess is that the code performance is limited by a hard disk read speed of approximately 100 MB/s. Of course, if you have an SSD, your mileage … Read more
[ad_1] Valgrind and GDB are very useful. The most previous one that I used was GDB- I like it because it showed me the exact line number that the Segmentation Fault was on. Here are some resources that can guide you on using GDB: GDB Tutorial 1 GDB Tutorial 2 If you still cannot figure … Read more
[ad_1] I guess you have specified the path to Internet Explorer like this “C:\Program Files\Internet Explorer\iexplore.exe” But because the \ character is an “escape” character in a literal string, you need to defeat the escape “C:\\Program Files\\Internet Explorer\\iexplore.exe” There was no error when you compiled because the compiler cannot check whether the command passed to … Read more
[ad_1] The problem is that you’re both looping and recursing. print(“22”, “”, 0); will recurse into print(“22”, “a”, 1); print(“22”, “b”, 1); print(“22”, “c”, 1); print(“22”, “a”, 2); print(“22”, “b”, 2); print(“22”, “c”, 2); and your extra bits are the last three calls. Get rid of the loop over the input digits (you’re already doing … Read more
[ad_1] Obviously there is a way to achieve this – but is it worth the effort? What you would need: A audio input stream. An spectrum analyzer (something like what this does: http://www.qsl.net/dl4yhf/spectra1.html – there are more than enough signal-processing papers out there). An digestive format to display it. A new view (depending on the … Read more
[ad_1] The snippet char *encrypt(char *string, size_t length) { } defines a function named encrypt, which takes a char * and a size_t as arguments, and returns a char *. As written, the function body is empty and will trigger at least one diagnostic because it isn’t returning a value. It looks like it’s meant … Read more
[ad_1] Just add one line of code after the cout statement as follow: if (mode == TOPIG) { cout << “TOPIG MODE” << endl; while (cin.good()){ getline(cin, lines); while (!looking) { spot = lines.find(” “); if (spot == -1){ looking = true; spot = lines.length( ); } line = lines.substr(0, spot); TP1stLetter(line); if (!looking) lines … Read more
[ad_1] I do not know what within() does, but you may want to use the new methods to generate random numbers introduced with C++11. The link has a nice example. In case the link will become invalid in some future time, here’s the relevant code: #include <iostream> #include <random> int main { // Seed with … Read more
[ad_1] Use a do…while loop like this: int I = 1; //Initialize to some non-zero number to prevent UB printf(“Enter 0 to quit \n”); do{ if (scanf(“%d”,&I) != 1) //If invalid data such as characters are inputted { scanf(“%*[^\n]”); scanf(“%*c”); //Clear the stdin } } while(I!=0); //Loop until `I` is not 0 This piece of … Read more
[ad_1] Of course using a string builder is very far from packet structuring, you must use byte[] and append values to it by index. 1 [ad_2] solved How to create a packet in C#
[ad_1] As every other person mentioned, you can use compiler options to reduce your size. At first, try to tweak these options for better result. These options normally affect size of your code. But if you have a lot of resources in your EXE/DLL, you will not see much difference. If you really need a … Read more
[ad_1] What if string is 0 length or count is 0? In your second case, you don’t return a value. This should be giving a compiler warning and will probably cause a crash as it returns whatever it wants. Edit Ok, the problem is deeper – you are never getting to the part of the … Read more
[ad_1] Well, i ll try to give you a quick example in Windows Forms. Like you said, you got 2 combo boxes Category and Brand, i named cmbParent and cmbChild. I declared some variables: List<String> listParent = new List<String>(); List<Tuple<String, String>> listChild = new List<Tuple<String,String>>(); On Form_Load, i did some manual lists: public ComboForm() { … Read more
[ad_1] You probably want this: for (l=0; l<ny; l++) { if (xflg) index = m * nxy + l*nx + k; else index = m * nxy + k*ny + l; vel[index] = velocity; fprintf(f,”%5d\n”,index); //<<< line added /* fprintf(stdout,”%.1f %.1f %.1f “, this_z, this_x, velocity); */ } or maybe this: for (l=0; l<ny; l++) … Read more
[ad_1] You will have to do it in a loop, like this: public static string getBetween(string strSource, string strStart, string strEnd) { int Start = 0, End = 0; StringBuilder stb = new StringBuilder(); while (strSource.IndexOf(strStart, Start) > 0 && strSource.IndexOf(strEnd, Start + 1) > 0) { Start = strSource.IndexOf(strStart, Start) + strStart.Length; End = … Read more
