need to recover password from this code - C# Discussion Boards

The proper location is in the same folder with the .EXE, usually in a folder under Program Files.

The problem is Program Files and everything under it is ReadOnly to normal users.

You really should NOT be writing to app.config. A proper method would be to write the changeable data to another config file in a folder under CommonAppData (see Environment.GetFolderPath).

So what is the proper method and what elements should be stored in the app.Exe.Config? I have a client application that stores both application settings and the connection strings to connect to the database.

Where can I find best practices on this?

I should clarify that you should put your changeable settings in a config file in a location appropriate for what your doing. User settings should go under a users profile, not under CommonAppData.

My question is: I want to know the index of /* and */ coming immediate before alpha2

Example:
hello world /* this is */ right way to get the index of /* track to */ alpha2 dummy text alpha dummy /* test */textalpha dummy text

Thanks in advance

A Regular Expression[^] is probably the simplest way:

C#

string input = @"hello world /* this is */ right way to get the index of /* track to */ alpha2 dummy text alpha dummy /* test */textalpha dummy text";
Regex pattern = new Regex(@"\/\*[^\*\/]*\*\/\s+alpha2");
Match match = pattern.Match(input);
if (match.Success)
{
    int theIndex = match.Index;
    ...
}

Thanks Homer,

Its good but is there any way without the regular expression as I have to search from a file and there are a lot of same keywords like alpha2. with this regular expression It will be difficult to find specific instance and its immediate before characters. Actually I have to track the keywords which are not coming in comments section. Not coming in /* */ and not started with //. comment may be of many lines. Can you please suggest the solution.

Thanks in advance.

That's not going to happen.

We're not going to reverse the strings for you because we have no idea who really owns that code. It's obfuscated for a reason.

Hi, I'm coding a C# program to include a dll I previously compiled but I keep getting the error:

C#

The type or namespace name 'Form' could not be found (are you missing a using directive or an assembly reference?)

The code is:

C#

using System;
using System.Threading;
using System.Collections.Generic;
using System.Reflection;
using System.IO;


namespace Threshold
{
    public partial class Form1 : Form
    {
        IDictionary<string, Assembly> _libs = new Dictionary<string, Assembly>();

		public Form1()
		{
    		AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
    		InitializeComponent();
		}
// yada yada yada...
}

I am probably just making a rookie mistake.

Please advise.

Thanks

You are using the class "Form", which is declared in the namespace "System.Windows.Forms". Add a using;

using System.Windows.Forms

..or use the classname and namespace to specify where you want to inherit from;

public partical class Form1 : System.Windows.Forms.Form

Also make sure you have a reference to the forms' assembly.

Now the errors are:

Only thing is I'm using Visual studio 2012 ultimate. I can't seem to find the assemblies in:

Any ideas?

The system assembly would already be in the references, if you created the project using VS. Are you mixing .NET framework versions?

What .NET version is the DLL targetting that you created?

Bastard Programmer from Hell Suspicious | :suss:

Ok, I understand your point. The dll was targetting .net v2.0 and the program .net v4.6.1

I rebuilt the dll targetting .net v4.6.1

Still the same issue after restarting the Visual studio.

Should work, might have problems if it was the other way around.

Only thing I can think of, is that you might be targetting the wrong CPU-type; if the DLL is compiled for 64 bits, and the app is targetting 32 bits, or the other way around.

Open up the csproj file in a text editor and look for this line:

XML

<Reference Include="System" />

If the line isn't there, include it alongside your other references.

Did you create a Console application by mistake? This is all setup for you already if you pick the Windows Forms Application project type.

Ok, created a new project for Windows form.

The recurring error now is:

C#

Invalid token '(' in class, struct, or interface member declaration

In the code:

C#

namespace Siren
{
    static class Program
    {
    public partial class Form1 : Form
    {
        IDictionary<string, Assembly> _libs = new Dictionary<string, Assembly>();

        // yada yada yada...

		int absW, absX, absY, absZ;
                
        // Your inputs here
        Console.Write("\nPlease input parameter 1 of first set... ");// Error occurs here...
        absW = Console.ReadLine();
     }
}
 static void Main()
 {
     Application.EnableVisualStyles();
     Application.SetCompatibleTextRenderingDefault(false);
     Application.Run(new Form1());
 }
}

The Console doesn't exist in a Windows Forms app.

Also, this looks like you're putting Console code into a Windows Forms project now, where before you where trying to use Windows Forms code in something other than a Windows Forms project.

So, which is it supposed to be? What are you really doing?

I'm being impatient because I expected to be done with this today. But since that is not going to happen, I'll stop cobbling things together and recode with fresh eyes tomorrow.
Thanks for the help.
Will get back to you.

Ehr.. stdout still exists in a WinForm. It is just a console-app that hides its console and puts up a GUI.
