For example, if you have a file in a folder named My Documents at the root of your C drive and the document name is document.doc, the full path is C:/MyDocuments/document.doc. To me, it seems that the current line has invalid path characters or something like that. Make sure that when reading the file paths from the list box, the full path to the file is first displayed in a correct format, that is: Should initialize the component, but rather throw the error that the path has no legal form. 3 – I tried Trim(),TrimEnd(),TrimStart() and it doesn`t work. Error: “The path is not of a legal form” Well, the path/file you gave an example of looks good. When I start, the message “The path has no legal form” appears. And sometimes when browsing, this is also displayed. What does that mean? The setting is applied only to the running application. It allows you to specify file paths as before the .NET 4.6.2 framework without getting System.ArgumentException. This, of course, is done through an exception, because the path is an illegal means for the class. There should be a backslash “ and not forward `/`@Pronner Does the problem correspond to the quoted text of protegesolutions or to the problem originally published with “The way is not of a legal form”? If this isn`t the original issue, can you open a separate GitHub issue? An exception occurred while processing pictureBox: System.InvalidOperationException: Invalid image data. —> System.ArgumentException: The path has no legal form. For example, he may include the path (which, according to him, has no legal form) in the message complaining that the path has no legal form.
Yes, it fits, it`s the same exception “The path is not of legal form”, and currently I can`t send a sample application, but it`s on the problem above: CmlLib/CmlLib.Core.Auth.Microsoft #11 A “path” is first of all the string that identifies where a file is located on your computer. So I can`t really say where it came from or what to do about it. But I can at least talk a little bit about what it means to have a legal form. Run the application again, let it read the text file – does it read it? (assuming the path seems correct) We tried to update our WebView2 control to the latest version, but once installed, our program throws this exception (nothing else has been changed in the code): ArgumentException: The path has no legal form. This gives all the information to find this file on your hard drive: What happens in a case like this (“This path is not a legal form”) is that there is some kind of error in the path specified by an application`s configuration setting. Open the text file, does the path look correct? (publish a single line) CoreWebView2Environment.SetLoaderDllFolderPath(loaderPath); The loaderPath value depends on the architecture of the process and in my case has the following format `{Release_program_path}runtimeswin-x86native`. It contains the WebView2Loader.dll file. It appears that the problem occurs in CoreWebView2Environment when you try to create such a path with the assembly. Current rental. This app works perfectly and makes no exceptions. It is essentially a form with a webView2 and navigates to a local HTML file.
The path is not a legal form An error message is raised when processing a Telerik.Reporting.Report in a project that targets the .NET 4.6.2 Framework. Save Listbox items (contains path and file name) Okay, I was able to solve this problem by explicitly creating the path .dll WebView2Loader. Here`s the code This happens when I just released main.xaml automation And it worked Which path is it exactly? Well, this of course (what I just described) has what I consider a “legal form”. There is some kind of mistake (like an illegal character or it can be something else) that makes everything that tries to deal with this path abandon; to say, “You know what? I can`t do with it what I have to do because it has an illegal form. It`s not fair. There is something wrong with this specification of a file. The exception occurs while processing a Telerik report that contains a resource specified by the file path, for example, =`C:PicturesMyImage.png.` as the PictureBox.Value property. @Kakooza-Allan-Klaus It could be that an invalid character occurs on your way. Use the following link to learn more: Hi.I gets the following error: “The path is not of legal form” in C# in code For example, you would have trouble creating a file whose file name contains a vertical bar. You would have trouble creating a file whose file name contains a greater than sign or a less than sign. In your foreached loop, first check the length of the line before proceeding with the code: To be honest, to be fair, this may not be something you`ve set up. It can be some sort of ill-defined configuration when configuring the program, or it can even be something that could even be modified by malware. I mean, there are a lot of different ways in which this kind of mistake can happen.
This means that something is being misconfigured on your computer. Additional context The component is used as a text box, it worked perfectly at version 1.0.1072.54 (the version on which it was built, and it also works for previous versions, which means that we tried to downgrade below 1.0.1072.54, and it always worked, trying to update it, but an error occurs as seen in the screenshots). Add the following setting in the runtime section of the running application configuration file: Hey @andrejapotic – thanks for the bug report, and sorry you are encountering it. This gives the impression that it could be related to #2372. If you encounter this, you can share the $exception. InnerException.StackTrace? Are you able to get a list of all the files it reads and view it here for our benefit and yours? In this way we can see on which line the error occurs and which entries are in the text file / table of rows The first 2 lines you posted – are they from the file itself or what goes through the foreach loop? The problem mentioned above is where my problem is. I would like to solve this problem as soon as possible Create a function to initialize the WebView2 control: New in Telerik Reporting? Download the 30-day free trial I`m really nervous about rolling out our class library – which is used in third-party applications – with WebView2, to be honest. It just seems difficult and fragile. We had to move away from the old WebBrowser control – the easiest thing in the world to integrate! – due to end-of-life and growing compatibility issues. We tried WebView, but it doesn`t work if the application is running as administrator (!!!) I wish they would keep things simpler. Well, what`s going on? If this happens at startup and it happens occasionally, the only way to know where it came from is to try to identify the program that is displaying the error message at the time of display. Yes, this hack doesn`t work for my client either, but it has another flaw.
Where does this problem come from? I mean, can I go back to the previous version because I don`t think we had it before. Then, in my desperation, I changed the compilation from Any CPU to x64 and it worked. I changed it back and forth and it worked sometimes, sometimes it didn`t. Then I removed some “junk” from the configurations and it worked with Any CPU and Prefer 32 bit, which I wanted. So, my suggestion for you is to check/play around/compare your project setups. The text was updated successfully, but the following errors occurred: As it appears at startup and sometimes with the browser, I would start with QuickTime, Java and Adobe Reader. These are often loaded at startup and used by some websites. It may also be that there is an entry somewhere that is an invalid entry that causes it to lift the exception. As you said, when the application is closed, the application rewrites the files to the text file – right? This is obviously not intentional, it is the app if we return the version to 1.0.1072.54: @Pronner FYI, we left the ship on this control. It`s too difficult and far too oversized for what we needed. The decisive factor was the need to provide chargers that could not be integrated as resources.
