![]() ![]() The following conditions may cause an exception: dll in the directory and adds them to ListBox1. The following example returns all files with the extension. Use the GetFiles method, supplying the name and path of the directory you want to search and specifying the pattern. I got the site out of source control but somehow or other it wouldn’t compile.For information about returning a file list by using the DirectoryInfo class of the System.IO namespace, see GetFiles. ![]() Today I was trying to fix up a website for one of our clients. Basically, it is the comma separated form of all the input fields with the given name. ![]() Will result in the value of “123,456” being stored in the string. In this case: string someName = Request.Form When the form fields are returned to the application and the field “some-name” is queried the result back is a combination of the two fields with the duplicate name. ![]() Here is an example of something similar: And these were now duplicated and as a result the previous and next buttons ceased to work. The previous and next buttons use hidden input field to tell the application which actual page number the buttons correspond to. Since the HTML was being built up in a string and dumped in a literal control in the first place the developer that was tasked with making the change just dumped the string into two literal controls, the original at the top of the page, and the new one at the bottom of the page. At some point a request had come in that the buttons needed to be replicated at the bottom of the page. The code created a set of pagination buttons at the top of the page with previous and next buttons. The other day I was trying to debug a bug in an application that I maintain. Tip of the Day #17: Duplicate input fieldsĭon’t allow duplicate input fields into your form. In my case, I renamed the field referring to the entities to offerTypeInformation. Rename one or other so that the names differ by more that case alone. One was called “ offerTypes” (in the code behind, an IEnumerable containing entities from the business layer), the other “ OfferTypes” (a ASP.NET Repeater control). The only difference between the two the case. The reason for this is that a control, in this case a Repeater, in the User Control had a similar name as a field on the code behind. This may or may not be relevant, but it reflects my set up at the time I discovered this issue. NET Framework Version:7.3053 ASP.NET Version:7.3053 System Information Source File: /WebSiteControls/Offers/TypeFilter.ascx Line: 1 Parser Error Message: Ambiguous match found. Please review the following specific parse error details and modify your source file appropriately. Then the compiler will output this: Tracer.WriteLine("I'm doing stuff.", "DoStuff", "c:\\dev\\spike\\Caller\\SomeOtherClass.cs", 7) Parser Error Message: Ambiguous match foundĭescription: An error occurred during the parsing of a resource required to service this request. So, if you write something like this: Tracer.WriteLine("I'm doing stuff.") What happens when you call Tracer.WriteLine is that the compiler injects literal values in place of the parameters. The lines with the file path and line numbers on them can be double-clicked in the Visual Studio output window and you will be taken directly to the line of code it references. Here is an example of the output: c:\dev\spike\Caller\Program.cs(13,0): MainĬ:\dev\spike\Caller\SomeOtherClass.cs(7,0): DoStuff The format that the full message is output in is also in a format where you can double click the line in the Visual Studio output window and it will take you to that line in the source. The above method can then be used to in preference to the built in Trace.WriteLine and it will output the details of where the message came from. MemberName,sourceFilePath,sourceLineNumber, for (int i = 30 i >= 0 i-)Ĭonsole.WriteLine("Waiting for debugger to attach. However there is something that can be done (if you have access to the source code and can rebuild). Or the thing you are debugging is in the start up code and there is no way to attach a debugger in time for that. If the process starts up, does its thing, then shuts down you might not have time to attach a debugger to it before the process has completed. I could potentially get VS to invoke the whole pipeline but it seemed to me a less convoluted process to try and attach the debugger to the running process and debug from there.īut what if the process is something quite ephemeral. In my case I have an assembly that is invoked from a wrapper that is itself invoked from an MSBuild script. Sometimes it is rather difficult to debug through Visual Studio directly even although the project is right there in front of you. ![]()
