LINQPad missing dll for Grpc

I am trying to test some methods in my library using Google API. More specifically the Cloud Vision API. When I reference the library in LINQPad I get an error
FileNotFoundException: Error loading native library. Not found in any of the possible locations: C:\Users\\AppData\Local\Temp\LINQPad5_dgzgzeqb\shadow_fxuunf\grpc_csharp_ext.x86.dll,C:\Users\\AppData\Local\Temp\LINQPad5_dgzgzeqb\shadow_fxuunf\runtimes/win/native\grpc_csharp_ext.x86.dll,C:\Users\\AppData\Local\Temp\LINQPad5_dgzgzeqb\shadow_fxuunf../..\runtimes/win/native\grpc_csharp_ext.x86.dll
I have tried copying the dll into all of these locations as well as my LINQPad Plugins and the LINQPad folder. I have tried clearing Cancel and Clear query thinking I needed to reset it. I have also closed and reopened LINQPad thinking maybe it re-scans the directory on load. None of this has worked. Has LINQPad changed where to put dlls or am I missing something?
I am using Google.Cloud.Vision.V1
`
var file = new byte[128];
var _settingsCon = new SettingConnector();
var apiKey = Task.Run(() => _settingsCon.Get("Google:Key")).Result.Value;
var credential = Google.Apis.Auth.OAuth2.GoogleCredential.FromJson(apiKey);
var channel = new Grpc.Core.Channel(
ImageAnnotatorClient.DefaultEndpoint.ToString(),
credential.ToChannelCredentials());
var builder = new StringBuilder();
var image = Image.FromBytes(file);
var client = ImageAnnotatorClient.Create(channel);
var response = client.DetectDocumentText(image);
foreach (var page in response.Pages)
{
foreach (var block in page.Blocks)
{
foreach (var paragraph in block.Paragraphs)
{
builder.Append(paragraph);
}
}
}
builder.ToString().Dump();`
This is essentially the function. The file is a dummy file that would be passed in. It shouldn't matter cause it can't make the request any way. The Dump is used instead of return.

C# - First step with Amazon MWS

I'm an Amazon FBA seller and I would like to begin to upload data regarding my sales in a more automated process using Amazon MWS. I just made an amazon MWS account and received my different IDs (Access Key Id, secret Access Key, ...).
I have the impression that most MWS developers use C#. I have a lot of Excel VBA experience but not in C#. Therefore, I'm not sure of the steps I have to follow.
On the webpage below, you can find a C# code that I would like to run:
http://www.samswiches.com/2011/02/how-to-use-amazon-mws-to-download-unshipped-order-reports/
Could you confirm the steps below are correct? :
1) Download Visual Studio => Do I need to download any extra package from Amazon?
2) In Visual Studio: File => New Project => C# console application
3) Erase all code and replace it by a copy-paste of the code found on above website => Do I need to put the code Inside something like "Sub - end Sub" in VBA?
4) Change "YourSecretKey", "YourSecretAccessKey", "YourSecretAccessKey", "YourMerchantID", "YourMarketplaceID" by my IDs.
5) Hit the run button
If it works, what will be the output like: An array inside Visual studio? A text file? A csv file? Where will it be stored?
I realize this is a very newbie question. However, I think that once I have a first code running correctly, my VBA experience will allow me to start efficiently from there.
Thanks in advance,
Diego.

After looking the code from http://www.samswiches.com/2011/02/how-to-use-amazon-mws-to-download-unshipped-order-reports/
I tried and changed something, and it works. Here is my solution:
Download the C# MWS Reports API Client Library: https://developer.amazonservices.com/doc/bde/reports/v20090101/cSharp.html
Use Visual Studio to create a project to get reports using MWS Reports API Client Library
Here is the code.
using System;
using System.Xml.Serialization;
using System.Collections.Generic;
using MarketplaceWebService;
using MarketplaceWebService.Mock;
using MarketplaceWebService.Model;
using System.IO;
using System.Threading;
public void testReport()
{
String accessKeyId = "Your Access Key ID";
String secretAccessKey = "Your Secret Access Key";
const string merchantId = "Merchant ID";
const string marketplaceId = "Marketplace ID";
MarketplaceWebServiceConfig config = new MarketplaceWebServiceConfig();
config.ServiceURL = "https://mws.amazonservices.com";
const string applicationName = "ApplicationName";
const string applicationVersion = "0.01";
MarketplaceWebServiceClient service =
new MarketplaceWebServiceClient(
accessKeyId,
secretAccessKey,
applicationName,
applicationVersion,
config);
RequestReportRequest reportRequestRequest = new RequestReportRequest();
reportRequestRequest.Merchant = merchantId;
// you can change ReportType here:
//http://docs.developer.amazonservices.com/en_IN/reports/Reports_ReportType.html
reportRequestRequest.ReportType = “_GET_FLAT_FILE_ACTIONABLE_ORDER_DATA_";
RequestReportResponse requestResponse = service.RequestReport(reportRequestRequest);
IdList lstRequestID = new IdList();
lstRequestID.Id.Add
(requestResponse.RequestReportResult.ReportRequestInfo.ReportRequestId);
GetReportRequestListRequest reportRequestListRequest = new
GetReportRequestListRequest();
reportRequestListRequest.Merchant = merchantId;
reportRequestListRequest.ReportRequestIdList = lstRequestID;
List<ReportRequestInfo> myListzz = new List<ReportRequestInfo>();
GetReportRequestListResponse reportRequestListResponse = new
GetReportRequestListResponse();
reportRequestListResponse =
service.GetReportRequestList(reportRequestListRequest);
GetReportRequestListResult reportRequestListResult = new
GetReportRequestListResult();
reportRequestListResult =
reportRequestListResponse.GetReportRequestListResult;
myListzz = reportRequestListResult.ReportRequestInfo;
if (myListzz.Count > 0)
{
while (myListzz[0].ReportProcessingStatus.ToString() != "_DONE_")
{
Console.WriteLine("Waiting for Report");
Thread.Sleep(61000);
reportRequestListResponse =
service.GetReportRequestList(reportRequestListRequest);
reportRequestListResult =
reportRequestListResponse.GetReportRequestListResult;
myListzz = reportRequestListResult.ReportRequestInfo;
}
if (myListzz[0].GeneratedReportId !=null)
{
GetReportRequest reportRequest = new GetReportRequest();
reportRequest.Merchant = merchantId;
String source = "C:\\myreport.txt";
reportRequest.ReportId = myListzz[0].GeneratedReportId;
reportRequest.Report = File.Open(source, FileMode.Create,
FileAccess.ReadWrite);
service.GetReport(reportRequest);
}
}
}

You are missing step 1b) Download the C# MWS Reports API Client Library. You may need other libraries to access other parts of the MWS API, but from a quick glance at that code above library is the main one.
Note that it refers to a lblStatus, which seems to be a label on a form, but nowhere in that post does it say anything else about that form. So step 2) probably is not a "console" style application, but a form based one, which also means, you shouldn't erase all code in step 3, but paste the code into whatever is the equivalent of a main() function (I've only ever used C and C++, but not C#, so I have no clue)

Vimeo: Get download link from API

I've Vimeo PRO and I'm trying to get the download link so the end user can download the video source. However, the lack of documentation makes it really hard to figure that out.
I'm trying VimeoDotNet but I cannot authenticate, I'm doing the following:
var client = new VimeoClientFactory().GetVimeoClient(key, secret)
var downloadLink = client.GetVideo(video_id).download;
However, the call to GetVideo throws an error saying I have to authenticate first, but I don't see how!
I've also tried with another VimeoClient, but it doesn't seem to implement the download link part.
Can anyone help? Or better yet, share a working example. Thanks.

After 2 days I was finally able to do it, I'll share what I did in case someone needs it. First, download this library:
https://github.com/saeedafshari/VimeoDotNet3
Open in Visual Studio and compile it. It's pretty simple so it compiled right away.
Then reference that compiled DLL from your project and do the following:
var VimeoClient3 = Vimeo.VimeoClient.ReAuthorize(_vimeoAccessToken,
_vimeoAppConsumerKey, _vimeoAppClientSecret);
// videoId is the ID of the video as in the public URL (eg, 123874983)
var result = VimeoClient3.Request("/videos/" + videoId, null, "GET");
if (result == null)
{
throw new Exception("Video not found.");
}
if (result["download"] == null)
{
throw new Exception("Download link not available.");
}
foreach (var item in (ArrayList)result["download"])
{
var downloadLinkInfo = item as Dictionary<string, object>;
if (downloadLinkInfo == null) continue;
// For example, get the link for SD quality.
// As of today, Vimeo was returning an HD quality and a 'mobile' one
// that is for streaming.
if (string.Equals((downloadLinkInfo["quality"] as string), "sd", StringComparison.InvariantCultureIgnoreCase))
{
return downloadLinkInfo["link"] as string;
}
}

CoolUtils TotalPDFPrinterX causes ASP C# site to crash

My company has purchased the CoolUtils TotalPDFPrinterX from https://www.coolutils.com/TotalPDFPrinterX
I make an HTTP PUT from Postman to the API and I get “Could not get any response”.
When running on my Windows machine the PDF prints fine however on the server the site crashes and in the event log I get the error "A process serving application pool '[MY_APP_POOL]' failed to respond to a ping. The process id was '[MY_PROCESS_ID]'."
Here is my C# code:
PDFPrinterX ppx = new PDFPrinterX();
ppx.Print(fileName, printerName, "-ap Default");
if (ppx.ErrorMessage != null)
{
WriteToSQL(id, false, ppx.ErrorMessage, 2);
Console.WriteLine(ppx.ErrorMessage);
}
By writing to the event log I know the site crashes on this line: PDFPrinterX ppx = new PDFPrinterX(); I have also surrounded the above code with a try catch and no exception is thrown. The site still crashes.
Things I have tried:
Uninstalling and Reinstalling the CoolUtils software
Giving EVERYONE Full control to the site folder and the CoolUtils program folder
Creating a C# desktop application using the same code. THIS WORKS FINE ON THE SERVER. It's just the ASP site that crashes.
Does anyone know what might be causing this?

The more I research this thing online the more I'm inclined to say that ActiveX which is the X in PDFPrinterX doesn't seem to work well when hosted in IIS.
I've seen a few forums where they say it works fine when they debug on localhost but when deployed to server is crashes.
...works fine when used inside localhost(Visual studio)
One of their feature pages shows that it requires Win 2000/NT/XP/2003/Vista/7
You should look into whether your server supports ActiveX components that can work in conjunction with IIS.
Looking at one of their other products support page: TotalPDFConverterX:
the following note in my opinion may also apply to TotalPDFPrinterX, given its dependency on ActiveX as well.
Note: Pay attention to some details during installation Total PDF Converter X:
Do not forget to register ActiveX in your web-server account.
Total PDF Converter X supports only Internet Explorer, Mozilla and Firefox browsers.
ActiveX works only with 32-bit internet information server. 64-bit server is not supported. Use command line version instead.

Thanks to #Nkosi I was able to find a workaround.
ActiveX works only with 32-bit internet information server. 64-bit server is not supported. Use command line version instead.
Our IIS server is 64 bit so that is what probably caused the site to hang up.
Buttt... the command line still worked in printing the PDFs on the server.
Client side code (makes the HTTP POST):
private void SendToPrinter(string fileName, string printerName, int id, decimal documentSequence)
{
// use http client to make a POST to the print api
using (var client = new HttpClient())
{
// compile the values string to transfer in POST
// should finish to look something like this:
// C:\print.pdf&PRTFTW_OFIT&ValShip-155320-1
var values = new Dictionary<string, string>
{
{ "", fileName + "&" + printerName + "&ValShip-" + id + "-" + documentSequence},
};
// URL encode the values string
var content = new FormUrlEncodedContent(values);
// make the POST
// DEBUG
var response = client.PostAsync("http://localhost:54339/api/print", content);
// retrieve the response
var responseString = response.Result.ToString();
}
}
Server side code (receives the HTTP POST):
using System;
using System.Net.Http;
using System.Web;
using System.Web.Http;
namespace api.valbruna.print.Controllers
{
public class PrintController : ApiController
{
// POST api/print
public HttpResponseMessage Post(HttpRequestMessage request)
{
try
{
// parse the content recieved from the client
var content = request.Content.ReadAsStringAsync().Result;
// decode the content, certain characters such as
// '&' get encoded to URL lingo such as '%26'
content = HttpUtility.UrlDecode(content);
// split the string into 3 seperate parts
String[] str = content.Split('&');
// remove the equal sign from the first string
str[0] = str[0].Trim('=');
// compile the arguments command line string
// should finish to look something like this:
// "C:\Program Files (x86)\CoolUtils\Total PDF PrinterX\PDFPrinterX.exe" "C:\print.pdf" -p"\\PRINTERS\PRTFTW_OFIT" -ap Default -log "C:\inetpub\logs\CoolUtils\log-ValShip-155320-4.txt" -verbosity detail"
String arguments = "\"" + str[0] + "\" -p\"\\\\PRINTERS\\" + str[1] +
"\" -ap Default -log \"C:\\inetpub\\logs\\CoolUtils\\log-" + str[2] +
".txt\" -verbosity detail";
// file location for PDFPrinterX.exe
String file = #"C:\Program Files (x86)\CoolUtils\Total PDF PrinterX\PDFPrinterX.exe";
// start the process
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
startInfo.FileName = file;
startInfo.Arguments = arguments;
process.StartInfo = startInfo;
process.Start();
return new HttpResponseMessage() { Content = new StringContent(content) };
}
catch (Exception e)
{
return new HttpResponseMessage() { Content = new StringContent(e.Message) };
}
}
}
}

How to launch a process which will open a text file in any editor and automatically move cursor to a certain line number?

From c#, I want to launch a process which will open a text file in any editor and automatically move cursor to a certain line number.
I can open a file using
Process.Start(#"c:\myfile.txt");
but I don't know how to move cursor at specific location in that file.
Answer with source code:
yes, I used notepad++
private void openLog() {
try {
// see if notepad++ is installed on user's machine
var nppDir = (string)Registry.GetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\Notepad++", null, null);
if (nppDir != null) {
var nppExePath = Path.Combine(nppDir, "Notepad++.exe");
var nppReadmePath = Path.Combine(yourDirectory,fileName );
var line = 20;
var sb = new StringBuilder();
sb.AppendFormat("\"{0}\" -n{1}", nppReadmePath, lineNo);
Process.Start(nppExePath, sb.ToString());
} else {
string newPath = #"\\mySharedDrive\notpad++\bin\notepad++.exe";
Process.Start(newPath, #"\\" + filePath + " -n" + lineNo); // take exe from my shared drive
}
} catch (Exception e) {
Process.Start(#"\\" + FilePath); // open using notepad
}
}

Get Notepad++, then you can do this:
var nppDir = (string)Registry.GetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\Notepad++", null, null);
var nppExePath = Path.Combine(nppDir, "Notepad++.exe");
var nppReadmePath = Path.Combine(nppDir, "readme.txt");
var line = 20;
var sb = new StringBuilder();
sb.AppendFormat("\"{0}\" -n{1}", nppReadmePath, line);
Process.Start(nppExePath, sb.ToString());
In this example we get install path of n++ from the registry, build path to exe and readme.txt file, opens its own readme.txt file with cursor on line 20.
Using StringBuilder is more efficient than using multiple appends (explanation somewhere on SO).

The solution very heavily depends on which process/editor is opened on your system. That editor would have to have a developer API that you could use to access functionality such as setting ranges and altering the cursor position. For example, if the editor that is opened is Microsoft Word, you would use the Word Interop API to set a selection at a specific position. There is no universal way to do this in 'any editor' since each one has its own API (or no outward facing API at all).

Perhaps you are going this the wrong way. I'm not sure what you are trying to accomplish, but I think it would be alot easier to just open the text file in an editor that belongs to your application. Perhaps another form with a WYSIWYG editor control. That way you have full control on where the cursor will land in that editor. Otherwise, there are just way too many unknowns for anything feasibly workable.
