Converter Hanging
pamar1908 opened this issue · comments
Hi, I am trying to run the following but it hangs at the converting line. I have tried without specifying the executable path as well. Thanks for any help.
Using conv As New Converter("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe") Dim ps As New Settings.PageSettings(Enums.PaperFormat.A4) conv.ConvertToPdf(html_text, "C:\Users\User\Downloads\mypdf.pdf", ps) End Using
Can you turn on logging and see in which steps the program failes?

For some reason it fails on the step Disabling caching, could you try not to disable the cache and see if that makes any difference?
How can I do this?
You probably set it to false from the Constructor
/// <summary>
/// Creates this object and sets it's needed properties
/// </summary>
/// <param name="chromeExeFileName">When set then this has to be the full path to the chrome executable.
/// When not set then then the converter tries to find Chrome.exe by first looking in the path
/// where this library exists. After that it tries to find it by looking into the registry</param>
/// <param name="userProfile">
/// If set then this directory will be used to store a user profile.
/// Leave blank or set to <c>null</c> if you want to use the default Chrome user profile location
/// </param>
/// <param name="logger">When set then logging is written to this ILogger instance for all conversions at the Information log level</param>
/// <param name="useCache">When <c>true</c> (default) then Chrome uses it disk cache when possible</param>

public Converter(string chromeExeFileName = null,

{Or you called the methode

#endregionI just released a new nuget package, please check if that fixes your issue
The new package cannot be installed due to the following:
Unable to find a version of 'AngleSharp' that is compatible with 'AngleSharp.Css 0.17.0 constraint: AngleSharp (>= 0.17.0 && < 0.18.0)', 'HtmlSanitizer 8.0.645 constraint: AngleSharp (= 0.17.1)'.
Weird, I did not get any errors when building the package... have to look into that.
Should be fixed in 2.6.9 ... there was a dependency problem between the AngleSharp packages
And?
Sorry we had some IT disaster today. Thank you very much for the releases. Unfortunately, it is still hanging at Enabling/Disabling Cashing (depending on setting).
@Sicos1977 Did you find anything under the hood creating this issue? Is this happening only to me?
Can you try and use normale Chrome (not the portabble version) and see if that makes any difference.
I am not using the portable version. I have Chrome normally installed on my Windows PC. I specified the exe path just because it was hanging and initially thought that it couldn't find Chrome's path
Ow... are u using Chrome from a windows service and is that service user running under local system?
Yes I am trying it locally on my PC.
Try running the Windows Service under another user... I had a simular problem when I did the same.
I am not running it as a Windows Service. I am running a Windows Forms app. I have also tried on another PC without any luck.
Did you find any reason why I might be getting the cashing error? Any way to bypass this? I have tried portable Chrome and it does the same
