Actually am going to delete the uploaded images. I have not used any Image or Bitmap, using HttpPostedFile class to upload images.
HttpPostedFile htp = (HttpPostedFile)dt.Rows[i]["postedfile"];
destination = Server.MapPath("~/ClientImages" + "\\Normal\\" + username + "\\" + date);
if (!System.IO.Directory.Exists(destination))
{
System.IO.Directory.CreateDirectory(destination);
}
htp.SaveAs(destination + "\\" + filename);
htp.InputStream.Close();
htp.InputStream.Dispose();
If i want to delete those images then am getting error.

I have a WPF app that gets data from a hardware device.
When the data comes in it is converted to a DataModel, then an event is raised called DataReceived. The View Model base class is subscribed to this event.
What I would like to do is have the event subscription in the base view model as an abstract class, but only have the correct implementation in the subclasses actually receive it.
See this[^]
Is this possible?
If it's not broken, fix it until it is
|
|
|
|
|
why not implement a filter event method then?
class BaseModel
{
internal virtual void OnReceive(EventModel ev)
{
if (HandleEvent(ev))
OnHandle(ev);
}
public virtual bool HandleEvent(EventModel ev) { return true;}
protected virtual void OnHandle(EventModel model) { }
}
You can even make the HandleEvent() method automatic using some generic constraint, if you so desire...
|
|
|
|
|
So it would be up to each subclass to determine if the event was handled?
If it's not broken, fix it until it is
|
|
|

Ok, so I modified your approach just a bit:
public abstract class BaseViewModel
{
public ViewTypes ViewType { get; protected set; }
public BaseViewModel()
{
ViewType = ViewTypes.None;
AppCore.DataReceived += AppCore_DataReceived;
}
public void AppCore_DataReceived(object sender, DataReceivedArgs args)
{
if (CanHandleDataReceived(args))
{
DataReceived(args);
}
}
protected virtual bool CanHandleDataReceived(DataReceivedArgs args)
{
return ViewType == args.ViewType;
}
protected abstract void DataReceived(DataReceivedArgs args);
}
The subclasses now only need to set the ViewType property. Then this code checks for the type and if it matches, calls the abstract DataReceived.
What do ya think?
If it's not broken, fix it until it is

Have a .net 4.0 application that when installed on Win 7 or 10 having issues with not being able to update the config file. Where is the proper location for the app.Exe.Config file?
|
|
|
|
|
The 'proper' location for app.exe.config is in the same directory/folder as app.exe
I'm not even sure if you can have app.exe.config in a different folder (if you're using the standard App Config do-dads) - I'd have to look it up
|
|
|
|
|
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?

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:
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.

Hi, I'm coding a C# program to include a dll I previously compiled but I keep getting the error:
The type or namespace name 'Form' could not be found (are you missing a using directive or an assembly reference?)
The code is:
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();
}
}
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.

Ok, that fixed that...
Now the errors are:
The type 'System.ComponentModel.IComponent' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
The type 'System.ComponentModel.ISynchronizeInvoke' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
The type 'System.ComponentModel.Component' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Only thing is I'm using Visual studio 2012 ultimate. I can't seem to find the assemblies in:
Project > Add Reference > Framework
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?
