Defining where files are installed - c#

I am trying to deploy a .NET application as a ClickOnce Application, but I am having trouble defining where the application is installed. I need to know this because I have to include support files. I have already added the support files as "existing items". I had assumed that the program would install in Program Files, but it does not exist there. Instead, there is just a shortcut on the desktop. Can someone explain how/where the install path is defined using VS2012?

One solution I found was to use some of the Application class properties to determine where ClicOnce installed an instance of my program. But be aware that some those are deleted on uninstall of the program.
// To get the path for the executable file that started the application, not including the executable name.
PATH_RESOURCES = Application.StartupPath ;
For persistant data I created references to specific paths like :
PATH_USERDATA = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\myAppName\";
if (!System.IO.Directory.Exists((string)PATH_USERDATA))
{
System.IO.Directory.CreateDirectory((string)PATH_USERDATA);
}
PATH_REPORTS = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + #"\myAppName\";
if (!System.IO.Directory.Exists((string)PATH_REPORTS ))
{
System.IO.Directory.CreateDirectory((string)PATH_REPORTS );
}

Clickonce application gets installed under the user profile, not the Program Files path.
On windows Vista and Windows 7, clickonce application path will be somewhere in c:\users\username\AppData\Local\Apps\2.0\
On Windows XP, clickonce application path will be somewhere in c:\document and Settings\username\LocalSettings\Apps\2.0\
Note that Clickonce application path is different everytime upon installation, I found the best way is to make your app to write its own app path to the reg key, this way you know exactly where the app path is by looking at the reg.

So as user831062 pointed out, ClickOnce apps get installed under the user profile, not the Program Files path. Because of this, the install directory is different on every machine and almost impossible to access directly.
The part that I was hung-up on, was where are the files that I have included in the project located, and more importantly - how do I access them?
Well, as mentioned IN THIS LINK, if you mark the file as a "data file", under:
Project Properties > Publish > Application Files > Publish Status
you'll be able to access them using something like:
textBox = File.ReadAllLines(ApplicationDeployment.CurrentDeployment.DataDirectory + #"\myFile.txt")).ToList();
If you don't mark it as a "data file", but rather as just an "Include (Auto)", it will just be located in the install directory itself, which can be accessed by calling the file directly using something like:
textBox = File.ReadAllLines(#"myFile.txt")).ToList();
Anyway, took me an hour or so to find this, so hopefully it helps someone else out.

If you have added your files to your project, set the property for "build action" to "content" and set "copy to output directory" to "copy always". This way, the files will be included in your deployment. When the application is run, retrieve the location of the assembly and look in the same relative folder as where they were included in the project. For example, if they are in the top folder of the build output directory (/bin/debug/ or /bin/release/), they will be included in the same folder as the executable, which you can discover using this:
System.Reflection.Assembly.GetExecutingAssembly().Location

ClickOnce not replacing App_Data files during re-install

I noticed a behavior I don't understand happening with my application's ClickOnce deployment: a database file (Main.accdb) that is marked as a data file isn't replaced in C:\Users\username\AppData\Roaming\AppName after re-installing or installing a newer version.
In the Project Properties > Publish > Application Files I have:
File Name App_Data\Main.accdb
Publish Status = Data File
Download Group = (Required)
Hash = Include
In the file properties I have:
Build Action = Content
Copy to Output Directory = Copy always
When I install my WPF application using ClickOnce the first time, the file is found in C:\Users\username\AppData\Roaming\AppName. However, if I uninstall, delete the file in that folder, and re-install it is not replaced. In fact, anything removed from that folder isn't replaced by re-installation.
I tried various options for the Publish Status but the same behavior happens regardless of which options I choose. I'm using WPF with C# in Visual Studio 2017.
Why is this happening and how can I make it so that the file is always there when the application installs (or even better, launches)?
It turns out that the App_Data folder behaves differently and the issue can be resolved by using a folder with any name except App_Data.
I can't find this documented anywhere except for a handful of forum posts of users with similar issues, however, I was able to verify that it all works exactly as expected once I changed the folder name.
All that being said, Microsoft does seem to want developers to use App_Data for databases, so perhaps this is an exception to the norm and may not be the right approach for most projects. In my case, it's a desktop application that needs to deploy a local Access database to the user's computer on install and keep it up to date/replaced during re-install and updates.

Visual Studio Moving a Content File on Publish

I'm developing a Web application that uses a couple XML files to store data. I have their Build Action set to Content, and on install the files are copied successfully to the Applications Virtual Directory:
C:\inetpub\wwwroot\ApplicationName\
The problem I'm having is that writing to these XML files (in order to save settings and things like that) causes a lot of write permissions issues. Therefore to get around it, I'm trying to copy these files from the virtual directory they're installed to to a new directory under the C drive, using the following PostBuildEvent in the Web Deployment Project:
xcopy "$(TargetDir)*.xml" "C:\CompanyName\ApplicationName\" /y
However, this does nothing. I'm not sure if this is because PostBuildEvents in the installer are not actually fired on install, but only on building the installer, or if TargetDir represents the bin directory:
C:\inetpub\wwwroot\ApplicationName\bin\
instead of the root application virtual directory:
C:\inetpub\wwwroot\ApplicationName\
Does anyone have any ideas? Has anyone dealt with this sort of thing before? I'm really stumped on this one.
Update:
I included a PostBuildEvent that should give full permissions to all users:
icacls "$(TargetDir)" /grant Users:F
But it doesn't seem to have resolved the problem.
I'm also unsure where exactly $(TargetDir) if pointing to, if it would be ..\ApplicationName\ or ..\ApplicationName\bin\
All you have to do is give full permissions to the user under whose context the Web Application Pool runs.
You can find this user by starting IIS manager and look at the Application Pools and Identity column
Something like
cacls C:\inetpub\wwwroot\ApplicationName /G Users:F
will give all permissions to this subdirectory to all users on the computer, If you are running under ApplicationPoolIndentity refer here
Turns out there's a much easier way to do what I was trying to do.
Instead of using PostBuildEvents to create a new directory structure and move files there, I added the new directory structure into
InstallerProject > View > File System
after which I located the Content Files from SomeProject entry in my installer project, and changed the Folder value to the newly specified directory structure, in this case
C:\CompanyName\ApplicationName\
This seems to work fine, I'm now able to access these files freely as I originally intended.

Working Directory in Visual Studio C# file

What exactly is Working Directory in the properties of Visual Studio C# project.
I have see a project where I right click and go to Properties and then I go to Debug tab, it shows me Working Directory where Author of the code has specified folder in local machine. I want to know what does that working directory means and what kinds of file will it store in that directory.
Thank you in advance.
Every process has a current Working Directory which is where all relative paths will be formed from. If not specified, this directory is the directory in which the active application started.
You can check which directory is set by calling:
System.IO.Directory.GetCurrentDirectory();
As mentioned above in a comment by #0xA3 this setting has no effect to your deployed product, it is is only for debugging.
The working directory of a project (and any Windows program in general) is the default place in which a program is looking up it's files. For example: My program has working directory C:\dir and tries to open test.txt, it would look in C:\dir\test.txt.
So every opened file will be opened relative to the working folder.
I think it will store nothing there, unless you add/write code in your application which explicitly creates files, either explicitly in the application's working directory, or implicitly specifying only a filename without specifying a directory at all.

C# console app deployment

I have a simple C# console application developed on my local machine using VS2008 Pro. I want to know how to deploy this solution onto a network share folder?
A similar Java console program is already placed (as a JAR file) in the same network share folder. Users simply open command prompt, navigate to shared folder and type "java -jar programName.jar inputParameter1 inputParameter2"
How can I achieve the same with .NET?
You can copy the exe over yourself, go to the bin folder in the directory your source code is in and copy it there.
or you can click the BUILD menu and use the PUBLISH menu item. This will allow you to enter the path to your network share and visual studio will copy the built app to the folder for you.
If your application is really "simple", you should be able to just copy the files to a shared folder and run it from there. However, if your "simple" application tries to do things that are restricted by the permissions you might have to configure them with caspol. Assemblies loaded from a shared drive have much fewer permissions than the ones loaded from a local drive.
It would be mostly the same process as the Java program. To deploy, compile the program and copy the exe from the bin folder (along with any dependencies) to the network share.
To run the program users would open the command prompt, navigate to shared folder, and type "programName.exe inputParameter1 inputParameter2"
You can use Publish feature of VS. Note that you can change settings in the Publish section of the console application project to remove some features that you don't need. For instance the renaming of .dll and .exe files by appending the '.deploy' extension to the name of the files or publishing in a new 'version' folder each time. Go to "Project Properties"->"Publish" and remove "Automatically increment revision" checkbox at "Publish Version", click "Options..." button and clear all checkboxes there too.
Right click your project, select publish which will make an executable, you can put that in your shared drive, similarly users can go into the command prompt and run it and give some args.
In the exact same way assuming they have the proper dependencies installed (.net, 3rd party assemblies, etc). copy the bin folder then have them execute the exe file.
Take a look at ClickOnce deployment:
ClickOnce is a Microsoft technology
for deploying Windows Forms or Windows
Presentation Foundation-based
software, also called Smart clients.
It is similar to Java Web Start for

a Problem with Windows Help Button (EDIT-New problem)

a strange behavior happens when install the application and then run the exe file.
first let me explain my steps:
1) i added HelpProvidor and i set HelpNameSpace property to the chm file path.
2) in the form properties i set HelpNavigator on helpProvidor property to : KeywordIndex
and HelpString on HelpProvidor to Use ASGATech Quran Sound Downloder Help
3) i created an installation pkg. and it runs successfuly.
My problem is when i debug the application and presses on "?" (which is the help button) it displays the chm file.
but when i run the sortcut on the desktop which has been created from the installation package it doesn't.
why is that the HelpNamespce is the same. and the exe which is in the Application folder is that same so why is that.
the exe file is the same and also when i created a new item in start -> program menu the exe file that created runs the chm file but the shortcut doesn't.
i put the chm with the application folder which throws the application folder on:
c:\program Files\Manufacturer\ProductName
and it put the file on this path successfuly so why he can't see it.
EDIT:
i found that the problem is when i uninstall the application it keeps the product folder
it only removes the icon ans chm and so when u reinstall the application he dont feel the new state (that he has chm file)
now how could i remove the product file from programFiles.
Are you sure the exe file is the same?
It seems that either the help file is not found by your application or that the current security settings of IE prevent it from being loaded.
Use a tool like Procmon to see where your application is looking for the help file.
If it is not found make sure that it is included within your installer package.
If it is found make sure that it is on the local disc and that the default security settings for your local machine have not been changed within IE.
