How to create Directory/File into IIS using ASP.NET C# Entity Framework

My work environment is:
Windows 7 Professional
Visual Studio 2019, ASP.NET MVC, Entity Framework
SQL Server Express
IIS Version 7.5 (installed locally)
When I debug in Visual Studio, the directory/file is created without problem inside this path ~/Content/Documentacion/log/ (using IIS Express that comes with VS).
But when I publish the solution and run it using IIS 7.5, the directory/file is not created, I cannot understand the problem.
This is the code:
public void CreaLogATiempos(DateTime fin, bool sobrescribir = false)
{
try
{
text = "xxxxx= ";
string docPath = "~/Content/Documentacion/log/" ;
var folder = System.Web.HttpContext.Current.Server.MapPath(docPath );
if (!Directory.Exists(folder))
{
Directory.CreateDirectory(folder);
}
FileInfo MyFile = new FileInfo(System.Web.HttpContext.Current.Server.MapPath(docPath + this.archivo));
if (!MyFile.Exists)
{
StreamWriter crear = new StreamWriter(System.Web.HttpContext.Current.Server.MapPath(docPath + this.archivo));
crear.WriteLine(text);
crear.Close();
}
else
{
StreamWriter crear = new StreamWriter(System.Web.HttpContext.Current.Server.MapPath(docPath + this.archivo), true);
crear.WriteLine(text);
crear.Close();
}
}
catch (Exception e)
{
Console.WriteLine("Exception: " + e.Message);
}
}
Maybe someone can see the error or has an idea about the problem?

Can I introduce you to TextWriterTraceListener? Add this to your Global.vb file:
'adding tracing to a log.
Trace.Listeners.Clear()
Dim stream As New IO.FileStream(Server.MapPath("~/App_Data/trace.log"), IO.FileMode.Append)
Dim writer As New IO.StreamWriter(stream, System.Text.Encoding.UTF8)
Dim logListener As New TextWriterTraceListener(writer, "trace.log")
Trace.Listeners.Add(logListener)
Trace.AutoFlush = True
Trace.WriteLine($"{DateTime.Now.ToString} - class: Global.asax - method: Application_Start - message: Trace listener loaded.")
Create a trace.log file inside "~/App_Data"

Select the project in visual studio and press ALT + Enter to open the settings property of that project as following picture
Picture
You can use this folder in your controller as following way
var physicalPath = Server.MapPath(Settings.Default.CompanyImagePath);

How to build multiple c# projects using MSBuild engine without using command prompt?

I am working on windows application project and from that project want to build different multiple c# projects which are in one solution of visual studio 2015 and also want them to be build programmatically individually using MSBuild tool without using command prompt and finally want to show the output in log file not in command prompt (means those project is building successfully or having any errors like this message in log file)
Do I need to use any MSBuild API and how to add in this project?
I have seen many questions like this (not exactly same) but it didn't work for me. please can anybody help me with this?

using Microsoft.Build.Evaluation;
using Microsoft.Build.Execution;
using Microsoft.Build.Logging;
...
public static BuildResult Compile(string solution_name, out string buildLog)
{
buildLog = "";
string projectFilePath = solution_name;
ProjectCollection pc = new ProjectCollection();
Dictionary<string, string> globalProperty = new Dictionary<string, string>();
globalProperty.Add("nodeReuse", "false");
BuildParameters bp = new BuildParameters(pc);
bp.Loggers = new List<Microsoft.Build.Framework.ILogger>()
{
new FileLogger() {Parameters = #"logfile=buildresult.txt"}
};
BuildRequestData buildRequest = new BuildRequestData(projectFilePath, globalProperty, "4.0",
new string[] {"Clean", "Build"}, null);
BuildResult buildResult = BuildManager.DefaultBuildManager.Build(bp, buildRequest);
BuildManager.DefaultBuildManager.Dispose();
pc = null;
bp = null;
buildRequest = null;
if (buildResult.OverallResult == BuildResultCode.Success)
{
Console.ForegroundColor = ConsoleColor.Green;
}
else
{
if (Directory.Exists("C:\\BuildResults") == false)
{
Directory.CreateDirectory("C:\\BuildResults");
}
buildLog = File.ReadAllText("buildresult.txt");
Console.WriteLine(buildLog);
string fileName = "C:\\BuildResults\\" + DateTime.Now.Ticks + ".txt";
File.Move("buildresult.txt", fileName);
Console.ForegroundColor = ConsoleColor.Red;
Thread.Sleep(5000);
}
Console.WriteLine("Build Result " + buildResult.OverallResult.ToString());
Console.ForegroundColor = ConsoleColor.Gray;
Console.WriteLine("================================");
return buildResult;
}
This is some old code I had lying around.
I use this to programatically build solutions and C# Projects. The output will be a BuildResult.Success or BuildResult.Failure.
The variable buildLog will contain the build output.
Note - the only way to access the build output that I am aware of is to use the above methodology of having a log file generated and then reading it in your C# code.
One thing to be aware of and I never did find a fix for this, is that the application that runs this code, may keep dll's it loads into memory from nuget package directories in memory. This makes deleting those directories problematic. I found a work around by having my application run as a MS Service - it seems when it runs as a local service, it has enough permissions to delete files held in memory.

Statically linking Mono using mkbundle in Windows

I'm having trouble statically linking Mono using mkbundle in Windows. In my attempts to figure out what's going on I hit a wall. When you pass the static flag to mkbundle in windows it looks for the file monosgen-2.0-static.lib in the mono directory. This directory is defined by the line the below:
string monoPath = GetEnv("MONOPREFIX", #"C:\Program Files (x86)\Mono");
The contents of this directory after installing mono 5.1.1 is:
First I noticed the file naming convention is different from that that mkbundle is looking for (monosgen-2.0 should be mono-2.0-sgen). I can change this just fine, however I suspect - given the file name - that the mono-2.0-sgen.lib file shown in the screenshot isn't statically compiled, as when I try to run my bundled application it first can't find the sgen dll, and then when it can it can't find others.
At this point I'm wondering if mkbundle officially works on Windows, and if it does am I doing something fundamentally wrong? I have seen older post asking for help setting mkbundle in Windows and have posted questions regarding this myself. Most point to using mingw instead of cl.exe. Should I be using this instead?
The source for this snippet is shown below. You can find the entire source code here https://github.com/mono/mono/blob/master/mcs/tools/mkbundle/mkbundle.cs.

Tesseract OCR simple example

Hi Can you anyone give me a simple example of testing Tesseract OCR
preferably in C#.
I tried the demo found here.
I download the English dataset and unzipped in C drive. and modified the code as followings:
string path = #"C:\pic\mytext.jpg";
Bitmap image = new Bitmap(path);
Tesseract ocr = new Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789"); // If digit only
ocr.Init(#"C:\tessdata\", "eng", false); // To use correct tessdata
List<tessnet2.Word> result = ocr.DoOCR(image, Rectangle.Empty);
foreach (tessnet2.Word word in result)
Console.WriteLine("{0} : {1}", word.Confidence, word.Text);
Unfortunately the code doesn't work. the program dies at "ocr.Init(..." line. I couldn't even get an exception even using try-catch.
I was able to run the vietocr! but that is a very large project for me to follow. i need a simple example like above.

Ok. I found the solution here
tessnet2 fails to load
the Ans given by Adam
Apparently i was using wrong version of tessdata. I was following the the source page instruction intuitively and that caused the problem.
it says
Quick Tessnet2 usage
Download binary here, add a reference of the assembly Tessnet2.dll to your .NET project.
Download language data definition file here and put it in tessdata directory. Tessdata directory and your exe must be in the
same directory.
After you download the binary, when you follow the link to download the language file, there are many language files. but none of them are right version. you need to select all version and go to next page for correct version (tesseract-2.00.eng)! They should either update download binary link to version 3 or put the the version 2 language file on the first page. Or at least bold mention the fact that this version issue is a big deal!
Anyway I found it.
Thanks everyone.

A simple example of testing Tesseract OCR in C#:
public static string GetText(Bitmap imgsource)
{
var ocrtext = string.Empty;
using (var engine = new TesseractEngine(#"./tessdata", "eng", EngineMode.Default))
{
using (var img = PixConverter.ToPix(imgsource))
{
using (var page = engine.Process(img))
{
ocrtext = page.GetText();
}
}
}
return ocrtext;
}
Info: The tessdata folder must exist in the repository: bin\Debug\

I was able to get it to work by following these instructions.
Download the sample code
Unzip it to a new location
Open ~\tesseract-samples-master\src\Tesseract.Samples.sln (I used Visual Studio 2017)
Install the Tesseract NuGet package for that project (or uninstall/reinstall as I had to)
Uncomment the last two meaningful lines in Tesseract.Samples.Program.cs:
Console.Write("Press any key to continue . . . ");
Console.ReadKey(true);
Run (hit F5)
You should get this windows console output

Try updating the line to:
ocr.Init(#"C:\", "eng", false); // the path here should be the parent folder of tessdata

I had same problem, now its resolved. I have tesseract2, under this folders for 32 bit and 64 bit, I copied files 64 bit folder(as my system is 64 bit) to main folder ("Tesseract2") and under bin/Debug folder. Now my solution is working fine.

In my case I had all these worked except for the correct character recognition.
But you need to consider these few things:
Use correct tessnet2 library
use correct tessdata language version
tessdata should be somewhere out of your application folder where you can put in full path in the init parameter. use ocr.Init(#"c:\tessdata", "eng", true);
Debugging will cause you headache. Then you need to update your app.config
use this. (I can't put the xml code here. give me your email i will email it to you)
hope that this helps

Here's a great working example project; Tesseract OCR Sample (Visual Studio) with Leptonica Preprocessing
Tesseract OCR Sample (Visual Studio) with Leptonica Preprocessing
Tesseract OCR 3.02.02 API can be confusing, so this guides you through including the Tesseract and Leptonica dll into a Visual Studio C++ Project, and provides a sample file which takes an image path to preprocess and OCR. The preprocessing script in Leptonica converts the input image into black and white book-like text.
Setup
To include this in your own projects, you will need to reference the header files and lib and copy the tessdata folders and dlls.
Copy the tesseract-include folder to the root folder of your project. Now Click on your project in Visual Studio Solution Explorer, and go to Project>Properties.
VC++ Directories>Include Directories:
..\tesseract-include\tesseract;..\tesseract-include\leptonica;$(IncludePath)
C/C++>Preprocessor>Preprocessor Definitions:
_CRT_SECURE_NO_WARNINGS;%(PreprocessorDefinitions)
C/C++>Linker>Input>Additional Dependencies:
..\tesseract-include\libtesseract302.lib;..\tesseract-include\liblept168.lib;%(AdditionalDependencies)
Now you can include headers in your project's file:
include
include
Now copy the two dll files in tesseract-include and the tessdata folder in Debug to the Output Directory of your project.
When you initialize tesseract, you need to specify the location of the parent folder (!important) of the tessdata folder if it is not already the current directory of your executable file. You can copy my script, which assumes tessdata is installed in the executable's folder.
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
api->Init("D:\tessdataParentFolder\", ...
Sample
You can compile the provided sample, which takes one command line argument of the image path to use. The preprocess() function uses Leptonica to create a black and white book-like copy of the image which makes tesseract work with 90% accuracy. The ocr() function shows the functionality of the Tesseract API to return a string output. The toClipboard() can be used to save text to clipboard on Windows. You can copy these into your own projects.

This worked for me, I had 3-4 more PDF to Text extractor and if one doesnot work the other one will ... tesseract in particular this code can be used on Windows 7, 8, Server 2008 . Hope this is helpful to you

Admittedly this is an older question when Tesseract 3 was the version available, but it came up in my search results while looking for a related issue and the question, and other answers, highlight the still valid issue of the difficulty of actually getting Tesseract installed, let alone configuring it to work correctly.
There is a far simpler solution (and using the updated Tesseract 5 engine) which does all the work for you, in IronOcr.
(Disclaimer: I do work for Iron Software, though I feel that others can benefit from this information, particularly as it relates to the question of using Tesseract OCR in C# which IronOcr excels at).
using IronOcr;
var Ocr = new IronTesseract(); // nothing to configure

{
OcrResult Result = Ocr.Read(Input);
foreach (var Page in Result.Pages)

ApplicationSettingsBase.Upgrade() Not Upgrading User Settings after Recompiling with .NET 4.0

I have a C# program that is using the standard ApplicationSettingsBase to save its user settings. This was working fine under .NET 3.5. And the provided Upgrade() method would properly "reload" those settings whenever a new version of my program was created.
Recently, I recompiled the program with .NET 4.0. My program's version number also increased. But, when I run this version, Upgrade() doesn't seem to to detect any previous version settings, and does not "reload" them. It starts blank.
As a test, I recompiled yet again, going back to .NET 3.5. And this time, the Upgrade() method started working again.
Is there a way to allow Upgrade() to work when switching frameworks? Is there something else I am missing?

I had exactly the same problem, and again I tested this several times from .NET 3.5 recomplied to .NET 4.0.
Unfortunately, my solution is in vb.net, but I'm sure you can use one of the many conversion programs to see this in c# such as http://www.developerfusion.com/tools/convert/vb-to-csharp/
It involves enumerating through all the folders in %AppData%\CompanyName to find the latest user.config file in a folder name of the version you wish to upgrade from.
I found that recompiling my app to .NET 4.0 under Visual Studio 2010 would create a new folder of name %AppData%\CompanyName\AppName.exe_Url_blahbahblah even though I had changed absolutely no other settings or code at all!
All my previous releases prior to .NET 4.0 retained the same folder name and upgraded successfully. Copying the old user.config file (and version folder name) from the old folder into the new folder structure created under .NET 4.0 (with the old version folder name) fixes the problem - it will now upgrade.
This example assumes you have a user setting named IUpgraded which is set to False by default (and later set to True) to check to see if the settings are initial defalt values or not - you may use any other variable you created instead. The example shows upgrading from version 1.2.0.0 to something later which you can change by changing the value of lastVersion.
The code is to be placed at the top of the form Load event of your latest (.NET 4.0) application version:
Imports System
Imports System.IO
If Not My.Settings.IUpgraded Then 'Upgrade application settings from previous version
My.Settings.Upgrade()
'The following routine is only relevant upgrading version 1.2.0.0
If Not My.Settings.IUpgraded Then 'enumerate AppData folder to find previous versions
Dim lastVersion As String = "1.2.0.0" 'version to upgrade settings from
Dim config_initial As System.Configuration.Configuration = System.Configuration.ConfigurationManager.OpenExeConfiguration(System.Configuration.ConfigurationUserLevel.PerUserRoamingAndLocal)
Dim fpath As String = config_initial.FilePath
For x = 1 To 3 'recurse backwards to find root CompanyName folder
fpath = fpath.Substring(0, InStrRev(fpath, "\", Len(fpath) - 1))
Next
fpath = fpath.Substring(0, Len(fpath) - 1) 'remove trailing backslash
Dim latestConfig As FileInfo 'If not set then no previous info found
Dim di As DirectoryInfo = New DirectoryInfo(fpath)
If di.Exists Then
For Each diSubDir As DirectoryInfo In di.GetDirectories(lastVersion, SearchOption.AllDirectories)
If InStr(diSubDir.FullName, ".vshost") = 0 Then 'don't find VS runtime copies
Dim files() As FileInfo = diSubDir.GetFiles("user.config", SearchOption.TopDirectoryOnly)
For Each File As FileInfo In files
Try
If File.LastWriteTime > latestConfig.LastWriteTime Then
latestConfig = File
End If
Catch
latestConfig = File
End Try
Next
End If
Next
End If
Try
If latestConfig.Exists Then
Dim newPath As String = config_initial.FilePath
newPath = newPath.Substring(0, InStrRev(newPath, "\", Len(newPath) - 1))
newPath = newPath.Substring(0, InStrRev(newPath, "\", Len(newPath) - 1))
newPath &= lastVersion
If Directory.Exists(newPath) = False Then
Directory.CreateDirectory(newPath)
End If
latestConfig.CopyTo(newPath & "\user.config")
My.Settings.Upgrade() 'Try upgrading again now old user.config exists in correct place
End If
Catch : End Try
End If
My.Settings.IUpgraded = True 'Always set this to avoid potential upgrade loop
My.Settings.Save()
End If

May this will help you :)

When Settings1.Upgrade() doesn't work as you espected, may try to delete previous user config files and try again.
In my case, Release and Debug versions are not correlative, then upgrade seems to fails because there is a conflict between versions in same directory related to debug/release outputs.
Clearing all previous user config files (appdata\local....) seems to solve the problem, calling Upgrade() works and the workaround proposed here works.
I hope it works for you.
