  • Image (?) File(?) Metadata(?) Properties(?)

    - by Marco Parenzan
    Sorry for the question marks, but a simple (I think) question has an impossible solution. From file system, if I click on an image file "Properties | Details tab" I access to many metadata. I need to access from a WPF application to the Description properties (Title, Subject, Rating, Tag and Comment). In particular Tag. I have found a lot of articles, many are very old. A few in WPF and Imaging library. But no one access to that properties. So the question marks: are these properties on image? On file system? I think they are on the image..I don0t undestand where are these properties and why is so difficult to access... Can someone help me? Thanks in advance, Marco Parenzan

  • Storing credit card details

    - by Andrew
    I have a business requirement that forces me to store a customer's full credit card details (number, name, expiry date, CVV2) for a short period of time. Rationale: If a customer calls to order a product and their credit card is declined on the spot you are likely to lose the sale. If you take their details, thank them for the transaction and then find that the card is declined, you can phone them back and they are more likely to find another way of paying for the product. If the credit card is accepted you clear the details from the order. I cannot change this. The existing system stores the credit card details in clear text, and in the new system I am building to replace this I am clearly not going to replicate this! My question, then, is how I can securely store a credit card for a short period of time. I obviously want some kind of encryption, but what's the best way to do this? Environment: C#, WinForms, SQL-Server.

  • How to assign class property as display data member in datagridview

    - by KoolKabin
    hi guys, I am trying to display my data in datagridview. I created a class with different property and used its list as the datasource. it worked fine. but I got confused how to do that in case we have nested class. My Classes are as follows: class Category property UIN as integer property Name as string end class class item property uin as integer property name as string property mycategory as category end class my data list as follows: dim myDataList as list(of Item) = new List(of Item) myDataList.Add(new Item(1,"item1",new category(1,"cat1"))) myDataList.Add(new Item(2,"item2",new category(1,"cat1"))) myDataList.Add(new Item(3,"item3",new category(1,"cat1"))) myDataList.Add(new Item(4,"item4",new category(2,"cat2"))) myDataList.Add(new Item(5,"item5",new category(2,"cat2"))) myDataList.Add(new Item(6,"item6",new category(2,"cat2"))) Now I binded the datagridview control like: DGVMain.AutoGenerateColumns = False DGVMain.ColumnCount = 3 DGVMain.Columns(0).DataPropertyName = "UIN" DGVMain.Columns(0).HeaderText = "ID" DGVMain.Columns(1).DataPropertyName = "Name" DGVMain.Columns(1).HeaderText = "Name" DGVMain.Columns(2).DataPropertyName = "" **'here i want my category name** DGVMain.Columns(2).HeaderText = "category" DGVMain.datasource = myDataList DGVMain.refresh() I have tried using mycategory.name but it didn't worked. What can be done to get expected result? Is there any better idea other than this to accomplish the same task? Edited My question as per comment: I have checked the link given by u. It was nice n very usefull. Since the code was in c# i tried to convert it in vb. Everything went good but failed at a point of case sensitive and next one is that i had my nested class name itemcategory and my property name was category. there it arouse the problem. it didn't searched for category but it searched for itemcategory. so confused on it. My Code as follows: Private Sub DGVMain_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DGVMain.CellFormatting Dim DGVMain As DataGridView = CType(sender, DataGridView) e.Value = EvaluateValue(DGVMain.Rows(e.RowIndex).DataBoundItem, DGVMain.Columns(e.ColumnIndex).DataPropertyName) End Sub Private Function EvaluateValue(ByRef myObj As Object, ByRef myProp As String) As String Dim Ret As String = "" Dim Props As System.Reflection.PropertyInfo() Dim PropA As System.Reflection.PropertyInfo Dim ObjA As Object If myProp.Contains(".") Then myProp = myProp.Substring(0, myProp.IndexOf(".")) Props = myObj.GetType().GetProperties() For Each PropA In Props ObjA = PropA.GetValue(myObj, New Object() {}) If ObjA.GetType().Name = myProp Then Ret = EvaluateValue(ObjA, myProp.Substring(myProp.IndexOf(".") + 1)) Exit For End If Next Else PropA = myObj.GetType().GetProperty(myProp) Ret = PropA.GetValue(myObj, New Object() {}).ToString() End If Return Ret End Function

  • Convert Date to Datetime field.

    - by infant programmer
    The argument my C# function is getting is a string which is merely a Date or a DateTime. I am suppose to convert this String to DateTime, to carry on furthure calculation. Now I need to test whether the incoming data is a Date, if it is date(examle:"12/31/2009"), then I need to add "00:00:00" (24 hours format) to it, so that it will become "12/31/2009 00:00:00". If string manipulation is one possible way, I want to confirm whether there is some other way where we can automate the testing and conversion within DateTime.TryParseExact() method. This is my sample C# code : (which is now only able to convert string of format "MM/dd/yyyy HH:mm:ss" to DateTime.) private static string[] formats = new string[] { "MM/dd/yyyy HH:mm:ss" }; public string date_conv(string date_str) { DateTime date_value; DateTime.TryParseExact(date_str, formats, new global::System.Globalization.CultureInfo("en-US"), global::System.Globalization.DateTimeStyles.None, out date_value); /*Some useful instruction to use date_value*/ return(date_value.ToString("MM/dd/yyyy HH:mm:ss")); }

  • Returning in a static class constructor

    - by Martijn Courteaux
    Hello, This isn't valid code: public class MyClass { private static boolean yesNo = false; static { if (yesNo) { System.out.println("Yes"); return; // The return statement is the problem } System.exit(0); } } This is a stupid example, but in a static class constructor we can't return;. Why? Are there good reasons for this? Does someone know something more about this? So the reason why I should do return is to end constructing there. Thanks

  • Setting a Forms Authentication cookie from a .NET client application

    - by Jon DellOro
    We currently have a .NET 2.0 web app that uses forms authentication via cookies. Associated with this web app is an old VB6 client application that has its own login system. Currently, the users have to login to the VB6 app, and then when they click on a link, need to authenticate themselves again with the .NET forms authentication system. I'm wondering if it's possible to create a client side .NET application, give it the username and password, and set the forms authentication cookie (without the browser being opened). Is that possible??

  • How do I get the XAML comiler to use textual content property on custom classes?

    - by Duncan
    Given a simple C# class definition like: [System.Windows.Markup.ContentProperty("PropertyOne")] public class SimpleBase { public string PropertyOne { get; set; } public string PropertyTwo { get; set; } } why is it not possible to ommit the sys:string tags around the word Test in the xaml below. <custom:SimpleBase x:Class="TestType" xmlns:custom="clr-namespace:ConsoleApplication1;assembly=" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:sys="clr-namespace:System;assembly=mscorlib"> <sys:String>Test</sys:String> </custom:SimpleBase> Somehow the compiler correctly coverts text to string for the type String, why doesn't it work for my custom type?

  • Remove .net ContextMenuStrip Padding

    - by Frosty840
    Hi, When creating a ContextMenuStrip, there is a huge amount of padding around the contained controls. For example: Me.myMenu = New ContextMenuStrip 'unset all obvious padding settings' Me.myMenu.ShowCheckMargin = False Me.myMenu.ShowImageMargin = False Me.myMenu.Margin = New System.Windows.Forms.Padding(0) Me.myMenu.Padding = New System.Windows.Forms.Padding(0) Dim addButton As New Button addButton.Size = New Size(60, 60) addButton.Text = "Button" Dim addControlHost As New ToolStripControlHost(addButton) Me.myMenu.Items.Add(addcontrolhost) Me.ContextMenuStrip = Me.myMenu This, ideally, would cause a 60x60 button to pop up at the cursor location. What actually pops up is this: The button is there, as expected, but despite there being no margin, no padding, and having set both Show*Margin settings to False, there is a massive border around the Button. I'm probably missing something blindingly obvious, but how can I get rid of all the white bordering, especially that huge right-hand margin?

  • New to asp.net. Need help debugging this email form.

    - by Roeland
    Hey guys, First of all, I am a php developer and most of .net is alien to me which is why I am posting here! I just migrated over a site from one set of webhosting to another. The whole site is written in .net. None of the site is database driven so most of it works, except for the contact form. The output on the site simple states there was an error with "There has been an error - please try to submit the contact form again, if you continue to experience problems, please notify our webmaster." This is just a simple message it pops out of it gets to the "catch" part of the email function. I went into web.config and changed the parameters: <emailaddresses> <add name="System" value="[email protected]"/> <add name="Contact" value="[email protected]"/> <add name="Info" value="[email protected]"/> </emailaddresses> <general> <add name="WebSiteDomain" value="hoyespharmacy.com"/> </general> Then the .cs file for contact contains the mail function EmailFormData(): private void EmailFormData() { try { StringBuilder body = new StringBuilder(); body.Append("Name" + ": " + txtName.Text + "\n\r"); body.Append("Phone" + ": " + txtPhone.Text + "\n\r"); body.Append("Email" + ": " + txtEmail.Text + "\n\r"); body.Append("Fax" + ": " + txtEmail.Text + "\n\r"); body.Append("Subject" + ": " + ddlSubject.SelectedValue + "\n\r"); body.Append("Message" + ": " + txtMessage.Text); MailMessage mail = new MailMessage(); mail.IsBodyHtml = false; mail.To.Add(new MailAddress(Settings.GetEmailAddress("System"))); mail.Subject = "Contact Us Form Submission"; mail.From = new MailAddress(Settings.GetEmailAddress("System"), Settings.WebSiteDomain); mail.Body = body.ToString(); SmtpClient smtpcl = new SmtpClient(); smtpcl.Send(mail); } catch { Utilities.RedirectPermanently(Request.Url.AbsolutePath + "?messageSent=false"); } } How do I see what the actual error is. I figure I can do something with the "catch" part of the function.. Any pointers? Thanks!

  • Servlet Session - switch from URL Rewriting to Cookie

    - by lajuette
    Situation: I have a "dumb" Javascript frontend that can contact some kind of SSO middleware (MW). The MW can obtain sessions by issuing requests that contain authentication credentials (username, password). I.e. the session will be created for a certain user. My frontend needs to "restart" the session to gain the user's permissions to the target system. For that i need a valid session cookie. The target system is not under my control (could be a more or less public WFS, WMS, etc.), so i cannot add any SSO mechanism to it. Question: Is it possible to "steal" a Session forging a request which URL contains a valid session ID in the jsessionid parameter? Goal : Issue such a request to a Servlet and make it respond with a Set-Cookie header that contains the same id. That way the frontend joins the session and may do whatever the user, which was used to create the session, is able to do.

  • jQuery datepicker - change "today" date?

    - by Newbie
    Hello! Is there a way to change the "today" date in jquery.ui datepicker? With today, I mean today (class="ui-datepicker-today") and not the minDate or the current-selected date! I figured out, that datepicker uses the system time for default values. Now I get the current date from my server and set it to my minDate. But I didn't find a way to set the today-date... It still uses my system date (there are some users out there whose systemdate is in the year 2000 or earlier). Can U help me plz?

  • How is method group overload resolution different to method call overload resolution?

    - by thecoop
    The following code doesn't compile (error CS0123: No overload for 'System.Convert.ToString(object)' matches delegate 'System.Converter<T,string>'): class A<T> { void Method(T obj) { Converter<T, string> toString = Convert.ToString; } } however, this does: class A<T> { void Method(T obj) { Converter<T, string> toString = o => Convert.ToString(o); } } intellisense gives o as a T, and the Convert.ToString call as using Convert.ToString(object). In c# 3.5, delegates can be created from co/contra-variant methods, so the ToString(object) method can be used as a Converter<T, string>, as T is always guarenteed to be an object. So, the first example (method group overload resolution) should be finding the only applicable method string Convert.ToString(object o), the same as the method call overload resolution. Why is the method group & method call overload resolution producing different results?

  • Need help regarding Async and fsi

    - by Stringer Bell
    I'd like to write some code that runs a sequence of F# scripts (.fsx). The thing is that I could have literally hundreds of scripts and if I do that: let shellExecute program args = let startInfo = new ProcessStartInfo() do startInfo.FileName <- program do startInfo.Arguments <- args do startInfo.UseShellExecute <- true do startInfo.WindowStyle <- ProcessWindowStyle.Hidden //do printfn "%s" startInfo.Arguments let proc = Process.Start(startInfo) () scripts |> Seq.iter (shellExecute "fsi") it could stress too much my 2GB system. Anyway, I'd like to run scripts by batch of n, which seems also a good exercise for learning Async (I guess it's the way to go). I have written some code and unfortunately it doesn't work: open System.Diagnostics let p = shellExecute "fsi" @"C:\Users\Stringer\foo.fsx" async { let! exit = Async.AwaitEvent p.Exited do printfn "process has exited" } |> Async.StartImmediate foo.fsx is just a hello world script. I'd like also to figure out if it's doable to retrieve a return code for each executing script and if not, find another way. Thanks!

  • Escaping Code for Different Shells

    - by Jon Purdy
    Question: What characters do I need to escape in a user-entered string to securely pass it into shells on Windows and Unix? What shell differences and version differences should be taken into account? Can I use printf "%q" somehow, and is that reliable across shells? Backstory (a.k.a. Shameless Self-Promotion): I made a little DSL, the Vision Web Template Language, which allows the user to create templates for X(HT)ML documents and fragments, then automatically fill them in with content. It's designed to separate template logic from dynamic content generation, in the same way that CSS is used to separate markup from presentation. In order to generate dynamic content, a Vision script must defer to a program written in a language that can handle the generation logic, such as Perl or Python. (Aside: using PHP is also possible, but Vision is intended to solve some of the very problems that PHP perpetuates.) In order to do this, the script makes use of the @system directive, which executes a shell command and expands to its output. (Platform-specific generation can be handled using @unix or @windows, which only expand on the proper platform.) The problem is obvious, I should think: test.htm: <!-- ... --> <form action="login.vis" method="POST"> <input type="text" name="USERNAME"/> <input type="password" name="PASSWORD"/> </form> <!-- ... --> login.vis: #!/usr/bin/vision # Think USERNAME = ";rm -f;" @system './login.pl' { USERNAME; PASSWORD } One way to safeguard against this kind of attack is to set proper permissions on scripts and directories, but Web developers may not always set things up correctly, and the naive developer should get just as much security as the experienced one. The solution, logically, is to include a @quote directive that produces a properly escaped string for the current platform. @system './login.pl' { @quote : USERNAME; @quote : PASSWORD } But what should @quote actually do? It needs to be both cross-platform and secure, and I don't want to create terrible problems with a naive implementation. Any thoughts?

  • Aop, Unity, Interceptors and ASP.NET MVC Controller Action Methods

    - by Richard Ev
    Using log4net we would like to log all calls to our ASP.NET MVC controller action methods. The logs should include information about any parameters that were passed to the controller. Rather than hand-coding this in each action method we hope to use an AoP approach with Interceptors via Unity. We already have this working with some other classes that use interfaces (using the InterfaceInterceptor). However, we're not sure how to proceed with our controllers. Should we re-work them slightly to use an interface, or is there a simpler approach? Edit The VirtualMethodInterceptor seems to be the correct approach, however using this results in the following exception: System.ArgumentNullException: Value cannot be null. Parameter name: str at System.Reflection.Emit.DynamicILGenerator.Emit(OpCode opcode, String str) at Microsoft.Practices.ObjectBuilder2.DynamicMethodConstructorStrategy.PreBuildUp(IBuilderContext context) at Microsoft.Practices.ObjectBuilder2.StrategyChain.ExecuteBuildUp(IBuilderContext context)

The if the user puts @a_registered_username i would like it to become a link to the user's profile. i think preg_replace is the function needed for this. $ALL_USERS_ROW *['USERNAME'] is the database query array for all the users and ['USERNAME'] is the username row. $content is the comment containing the @username i think this should not be very hard to solve for someone who is good at php. Does anybody have any idea how to do it?

  • Can EC2 instances be set up to come from different IP ranges?

    - by Joshua Frank
    I need to run a web crawler and I want to do it from EC2 because I want the HTTP requests to come from different IP ranges so I don't get blocked. So I thought distributing this on EC2 instances might help, but I can't find any information about what the outbound IP range will be. I don't want to go to the trouble of figuring out the extra complexity of EC2 and distributed data, only to find that all the instances use the same address block and I get blocked by the server anyway. NOTE: This isn't for a DoS attack or anything. I'm trying to harvest data for a legitimate business purpose, I'm respecting robots.txt, and I'm only making one request per second, but the host is still shutting me down. Edit: Commenter Paul Dixon suggests that the act of blocking even my modest crawl indicates that the host doesn't want me to crawl them and therefore that I shouldn't do it (even assuming I can work around the blocking). Do people agree with this?
