while-loop

I have code that opens the OpenFileDialog, I'm checking the size of the file to make sure it doesn't exceed specific limit. But, if the user selected a big sized file I need to warn him and lead him back to the dialog to select a different file or click cancel. This is what I've tried: OpenFileDialog dialog = new OpenFileDialog(); dialog.Filter = "Jpeg files, PDF files, Word files|*.jpg;*.pdf;*.doc;*.docx"; while (dialog.ShowDialog() != DialogResult.Cancel) { var size = new FileInfo(dialog.FileName).Length; if (size > 250000) { MessageBox.Show("File size exceeded"); continue; } } EDIT: I also

There are several postings concerning switch statements within while loops, except for the fact that none of them are done in C, at least from what I've seen. C++ can create boolean expressions, which I'm aware of, but not in C. I have a while loop that contains a switch control. However, when I write break statements within my switch, it goes back to the beginning of the loop and makes my program run forever. Ignore the functions I use, for they work for sure. I just need some clarification on my handling of the nesting. Thanks! Here is my main.c: while(1) { printf("0) Exit\n1) List Tasks\n2)

Is the C++ code below legal, or is there a problem with my compiler? The code was complied into a shared library using gcc version 4.4.6 20110731 (Red Hat 4.4.6-3) (GCC) and openMP and then called via R 2.15.2. int it=0; #pragma omp parallel sections shared(it) { #pragma omp section { std::cout<<"Entering section A"<<std::endl; for(it=0;it<10;it++) { std::cout<<"Iteration "<<it<<std::endl; } std::cout<<"Leaving section A with it="<<it<<std::endl; } #pragma omp section { std::cout<<"Entering section B with it="<<it<<std::endl; while(it<10) { 1; } std::cout<<"Leaving section B"<<std::endl; } } I

I have to write a function of the following method : Rejection method (uniform envelope) : Suppose that fx is non-zero only on [a, b], and fx ≤ k. Generate X ∼ U(a, b) and Y ∼ U(0, k) independent of X (so P = (X, Y ) is uniformly distributed over the rectangle [a, b] × [0, k]). If Y < fx(x) then return X, otherwise go back to step 1. rejectionK <- function(fx, a, b, K) { # simulates from the pdf fx using the rejection algorithm # assumes fx is 0 outside [a, b] and bounded by K # note that we exit the infinite loop using the return statement while (TRUE) { x <- runif(1, a, b) y <- runif(1, 0, K

I have a PHP script that seemed to stop running after about 20 minutes. To try to figure out why, I made a very simple script to see how long it would run without any complex code to confuse me. I found that the same thing was happening with this simple infinite loop. At some point between 15 and 25 minutes of running, it stops without any message or error. The browser says "Done". I've been over every single possible thing I could think of: set_time_limit ( session.gc_maxlifetime in the php.ini) memory_limit max_execution_time The point that the script is stopped is not consistent. Sometimes

Im trying to loop though a string with HTTP links inside and newlines, I want to loop over a line at a time. At the moment I have echo -e "$HTTP_LINKS" | while read HTTP_S_LINK ; do TEST_STRING="test" done But this way I don't have access to the TEST_STRING out side the loop, which is what I want. I'm using the while loop so that it will loop though each newline in $HTTP_LINKS and not just the words in the string. (I don't want to use a for loop with IFS set to \n) I thought maybe I could just do something like this #!/bin/bash while read HTTP_S_LINKS do TEST_STRING="test2" done < $HTTP_LINKS
