问题 I'm trying to replace Thread.Sleep with System.Threading.Timer, and I'm trying to implement it in the following code. The main reason for changing is that, even though it works when testing locally, it's not working properly in the server. Plus, I've read that using it here is bad practice. I've seen several examples (including the one below), but I'm not certain how I could use it in my case: System.Threading.Timer in C# it seems to be not working. It runs very fast every 3 second In my

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I want the program to check if it's installed on the computer (using Clickonce) or just being run (e.g. by Visual Studio).

问题 I had a terrible time with file input from command line arguments last semester and I need to utilize it for an exercise that I am working on. I have coded a simple shell just to get it working: prob_5.c #include <stdio.h> int main(int argc, char *argv[]) { int i; FILE *fp; int c; for (i = 1; i < argc; i++) { fp = fopen(argv[i], "r"); if (fp == NULL) { fprint(stderr, "cat: can't open %s\n", argv[i]); continue; } while ((c = getc(fp)) != EOF) { putchar(c); } fclose(fp); } return 0; } I can't

问题 I am trying to add syntax highlighting for a custom content type based on text e.g. static class RTextContentType { public const string ContentTypeName = Constants.CONTENT_TYPE; [Export, Name(ContentTypeName), BaseDefinition("text")] internal static ContentTypeDefinition ContentTypeDefinition = null; // set via MEF } Then the classifier provider is declared like this, [Export(typeof(IClassifierProvider)), ContentType(Constants.CONTENT_TYPE)] class RTextClassifierProvider : IClassifierProvider

问题 We are developing addin for Visual Studio. It creates items in Solution Explorer context menu. The problem is when we remove the addin, menu item is still there but without icon. When I click on it, VS propose to remove the command. See screenshot. How should they be uninstalled to remove the command? At the moment I just remove the addin file from "Visual Studio 2012\Addins" folder during uninstall. I'm using class Connect : IDTExtensibility2 回答1: One option is to run a .vbs script on

问题 I was given a webproject written with aspx/c#. When I loaded it into Visual Studio 2010, I got many error telling me that some controls in the code-behind files do not exist in the current context. I checked for the common pitfalls, like wrong code-behind file name, missing runat -attribute, restart VS, reload project, yet nothing resolves the error. What else can I do to check where the problem is? 回答1: Try to change the code-behinde to CodeFile="where code locate", then it probably will
