Asp debug tool

You can do the following things using the features of Microsoft Script Debugger:. Open a command window to monitor the value of variables, properties, or array elements, during the execution of your server-side scripts. Set pauses to suspend execution of your server-side scripts using either the debugger or a script command at a particular line of script. You cannot use Microsoft Script Debugger to directly edit your scripts, only to locate bugs.

To fix bugs, you must edit your script with an editing program, save your changes, and run the script again. Before you can begin debugging your server-side scripts, you must first configure your Web server to support ASP debugging.

Under Application Settings , click Configuration. An application must be created for the button to be active. After enabling Web server debugging, you can use either of the following methods to debug your scripts:. Use Internet Explorer to request an. If the file contains a bug or an intentional statement to halt execution, Script Debugger will automatically start, display your script, and indicate the source of the error.

While debugging your server-side scripts you might encounter several types of errors. Some of these errors can cause your scripts to execute incorrectly, halt the execution of your program, or return incorrect results. A syntax error is a commonly encountered error that results from incorrect scripting syntax.

For example, a misspelled command or an incorrect number of arguments passed to a function generates an error. Syntax errors can prevent your script from running. Run-time errors occur after your script commences execution and result from scripting instructions that attempt to perform impossible actions.

New Post. Matthew Louden. I want to know what's the best way to debug ASP pages? Now, I just put the following code when I got run-time error, but sounds like not efficient. Please advice! Write "Here" Response. Follow Post Reply. Visual Interdev Real debugging like in Visual Basic : line by line, asking values of variables, set a watch, change variables in runtime etc.

State 'etc. I guess if you're talking about debugging during development, then this may not be as much of an interest to you, but you can read more here For guidance on configuring VS Code assets in the. Only browser debugging is supported at this time.

You can't automatically rebuild the backend Server app of a hosted Blazor WebAssembly solution during debugging, for example by running the app with dotnet watch run. To attach to a running Blazor app, create a. Attaching to a debugging session is only supported for standalone apps. To use full-stack debugging, you must launch the app from VS Code.

The following launch configuration options are supported for the blazorwasm debug type. In the browser, navigate to Counter page and select the Click me button to hit the breakpoint:. For more information, see Debugging with Visual Studio for Mac. The browser must be running with remote debugging enabled, which isn't the default.

If remote debugging is disabled, an Unable to find debuggable browser tab error page is rendered with instructions for launching the browser with the debugging port open. Follow the instructions for your browser, which opens a new browser window. Close the previous browser window. Once the browser is running with remote debugging enabled, the debugging keyboard shortcut in the previous step opens a new debugger tab.

After a moment, the Sources tab shows a list of the app's. In component code. After a breakpoint is hit, single-step F10 through the code or resume F8 code execution normally. Blazor provides a debugging proxy that implements the Chrome DevTools Protocol and augments the protocol with. NET-specific information. When debugging keyboard shortcut is pressed, Blazor points the Chrome DevTools at the proxy. The proxy connects to the browser window you're seeking to debug hence the need to enable remote debugging.

Browser source maps allow the browser to map compiled files back to their original source files and are commonly used for client-side debugging. Instead, Blazor does IL interpretation within the browser, so source maps aren't relevant.

If a firewall blocks communication with the debug proxy, create a firewall exception rule that permits communication between the browser and the NodeJS process. Modification of a firewall configuration must be made with care to avoid creating security vulnerabilities.

Carefully apply security guidance, follow best security practices, and respect warnings issued by the firewall's manufacturer. If possible, only allow open communication with the NodeJS process on trusted or private networks. For more information, see Windows Defender Firewall with Advanced Security and related articles in the Windows Firewall documentation set. We recommend adding a delay at the start of the method body to give the debug proxy some time to launch before the breakpoint is hit.

You can include the delay based on an if compiler directive to ensure that the delay isn't present for a release build of the app. OnInitialized :. OnInitializedAsync :. If Visual Studio throws an exception that the debug adapter failed to launch mentioning that the timeout was reached, you can adjust the timeout with a Registry setting:.

For example, one minute is assigned as If Microsoft Edge is used for debugging instead of Google Chrome, the. The Server project's folder is typically named Server in a solution based on the hosted Blazor WebAssembly project template.
