  • Load an Assembly from Bin in ASP.NET

    - by Pete Michaud
    I have a file name, like "Foo.dll," for a library that I know is in the bin directory. I want to create an Assembly object for it. I'm trying to instantiate this object from a class that's not a page, so I don't have the Request object to get the path. How do I get the path I need to use Assembly.Load()?

  • Webbrowser control and cookies

    - by Mike
    Hello! I have a webbrowser control in my program and what I want to do is to delete all the cookies stored in my computer. The problem is that for example I'm in some site, and then I decide I want to delete all the cookies, so I do it by the command "Kill()" but the problem is that the cookies remain and this site still can recognize me, and to complete the kill command I need to close my program and enter it again. The webbrowser control uses Internet Explorer, and I think when you enter IE it somehow loads all the cookies into it so if you delete your cookies, they remain there. So I'm wondering how can I delete my cookies, completely delete them without the need to close my program and enter it once again. Any help will be appreciated!

  • Best way to run remote VBScript in ASP.net? WMI or PsExec?

    - by envinyater
    I am doing some research to find out the best and most efficient method for this. I will need to execute remote scripts on a number of Window Servers/Computers (while we are building them). I have a web application that is going to automate this task, I currently have my prototype working to use PsExec to execute remote scripts. This requires PsExec to be installed on the system. A colleague suggested I should use WMI for this. I did some research in WMI and I couldn't find what I'm looking for. I want to either upload the script to the server and execute it and read the results, or already have the script on the server and execute it and read the results. I would prefer the first option though! Which is more ideal, PsExec or WMI? For reference, this is my prototype PsExec code. This script is only executing a small script to get the Windows OS and Service Pack Info. Protected Sub windowsScript(ByVal COMPUTERNAME As String) ' Create an array to store VBScript results Dim winVariables(2) As String nameLabel.Text = Name.Text ' Use PsExec to execute remote scripts Dim Proc As New System.Diagnostics.Process ' Run PsExec locally Proc.StartInfo = New ProcessStartInfo("C:\Windows\psexec.exe") ' Pass in following arguments to PsExec Proc.StartInfo.Arguments = COMPUTERNAME & " -s cmd /C c:\systemInfo.vbs" Proc.StartInfo.RedirectStandardInput = True Proc.StartInfo.RedirectStandardOutput = True Proc.StartInfo.UseShellExecute = False Proc.Start() ' Pause for script to run System.Threading.Thread.Sleep(1500) Proc.Close() System.Threading.Thread.Sleep(2500) 'Allows the system a chance to finish with the process. Dim filePath As String = COMPUTERNAME & "\TTO\somefile.txt" 'Download file created by script on Remote system to local system My.Computer.Network.DownloadFile(filePath, "C:\somefile.txt") System.Threading.Thread.Sleep(1000) ' Pause so file gets downloaded ''Import data from text file into variables textRead("C:\somefile.txt", winVariables) WindowsOSLbl.Text = winVariables(0).ToString() SvcPckLbl.Text = winVariables(1).ToString() System.Threading.Thread.Sleep(1000) ' ''Delete the file on server - we don't need it anymore Dim Proc2 As New System.Diagnostics.Process Proc2.StartInfo = New ProcessStartInfo("C:\Windows\psexec.exe") Proc2.StartInfo.Arguments = COMPUTERNAME & " -s cmd /C del c:\somefile.txt" Proc2.StartInfo.RedirectStandardInput = True Proc2.StartInfo.RedirectStandardOutput = True Proc2.StartInfo.UseShellExecute = False Proc2.Start() System.Threading.Thread.Sleep(500) Proc2.Close() ' Delete file locally File.Delete("C:\somefile.txt") End Sub

  • Error when passing quotes to webservice by AJAX

    - by Radu
    I'm passing data using .ajax and here are my data and contentType attributes: data: '{ "UserInput" : "' + $('#txtInput').val() + '","Options" : { "Foo1":' + bar1 + ', "Foo2":' + Bar2 + ', "Flags":"' + flags + '", "Immunity":' + immunity + '}}', contentType: 'application/json; charset=utf-8', Server side my code looks like this: <WebMethod()> _ Public Shared Function ParseData(ByVal UserInput As String, ByVal Options As Options) As String The userinput is obvious but the Options structure is like the following: Public Structure Options Dim Foo1 As Boolean Dim Foo2 As Boolean Dim Flags As String Dim Immunity As Integer End Structure Everything works fine when $('#txtInput') contains no double-quotes but if they are present I get an error (for an input of asd"): {"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected.

  • Convert Null Value to String - C#.NET

    - by peace
    foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { PropertyItem.SetValue(this, objDataTable.Rows[0][PropertyItem.Name.ToString()], null); } In one of the loops i get this exceptional error: Object of type 'System.DBNull' cannot be converted to type 'System.String'. The error occurs because one of the fields in the database has no value (null), so the string property could not handle it. How can i convert this null to string? I got this solution If you know a shorter or better one, feel free to post it. I'm trying to avoid checking on every loop is current value is null or not.

  • How to override event on a UserControl

    - by Vadim
    Hello! I have a WinForms application (OwnerForm) with some UserControl. When textbox of UserControl is changed, I want to filter content of a OwnerForm. But how can I make it? I don't want to specify OwnerForm inside the user control. I know a solution to add manually handlers for MyUserControl.tb.TextChanged to some functions on a owner form, but I think it's bad way. I'll prefer to have overridable functions, but I can't imagine how to do it. Any suggestions? Thanks in advance,

  • Dynamically creating objects at runtime that inherit from a base class

    - by Homeliss
    I am writing a game editor, and have a lot of different "tool" objects. They all inherit from BTool and have the same constructor. I would like to dynamically populate a toolbox at runtime with buttons that correspond to these tools, and when clicked have them create an instance of that tool and set it as the current tool. Is this possible, and if so will it be better/easier than creating those buttons by hand?

  • My Lucene queries only ever find one hit

    - by Bob
    I'm getting started with Lucene.Net (stuck on version 2.3.1). I add sample documents with this: Dim indexWriter = New IndexWriter(indexDir, New Standard.StandardAnalyzer(), True) Dim doc = Document() doc.Add(New Field("Title", "foo", Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) doc.Add(New Field("Date", DateTime.UtcNow.ToString, Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) indexWriter.AddDocument(doc) indexWriter.Close() I search for documents matching "foo" with this: Dim searcher = New IndexSearcher(indexDir) Dim parser = New QueryParser("Title", New StandardAnalyzer()) Dim Query = parser.Parse("foo") Dim hits = searcher.Search(Query) Console.WriteLine("Number of hits = " + hits.Length.ToString) No matter how many times I run this, I only ever get one result. Any ideas?

  • Form Inheritance in Visual Studios designer implementations

    - by CooPzZ
    I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

  • Compiling a click-once app that requires administrator?

    - by Assimilater
    Hi, a lot of my programs require the ability to write files to the hard drive. When I first made these programs for XP they worked great. Now I'm less ignorant about UAC (got a new laptop recently). And for future customers...I've noticed the potential for a LOT of annoying error messages....and quite frankly if the program can't write data to the hard drive or thumb drive it's on...there's no point to running it.... I've tried multiple times to build in the manifest a requirement for administrator or user access....I'm not sure if anything less would solve the problem...but have failed because click-once has security features in place to prevent me from doing so. I'd rather not have to tell my customers how to make the program run as an administrator by editing the file's properties...I'd much rather have a convenient pop up like what you'd see new programs such as Itunes or Filezilla show if they were in conflict with UAC requesting the privileges they need. I'd really like to do this but have had little success. Any and all advice that can remedy this grievous problem appreciated. Thanks.

  • Wnat is the preferred method of building extremely lightweight business object / DAL now that I have

    - by Seth Spearman
    Hello, I have completed a simple database for a project. Only 6tables. Of the 6, one is a "lookup" table. There is one "master" table that is the driver for the system. It is referenced as a foreign key by the other four tables. Give that this step is completed. What is the FASTEST, EASIEST way to create POCOs/BizObjects that can load load the data and the child data. Here are my CAVEATS. *I don't want to spend more than 30-60 minutes learning how? *There is very little biz logic needed in the POCOs. They will pretty much load data. Don't even really need to write back data. *I already know CSLA (up to version 3) but I feel that is overkill for this little project. *Nevertheless, I would love it if it ROOT objects could have collection classes that contain the CHILD objects as in CSLA...but again, without using CSLA. *Please give the answer for .NET 35 but also if I was restricted to only use .NET 20. *Ideally I could just point a tool at the database and the POCOs would be genn'ed. *FREE Just curious what you guys use for this kind of scenario. I understand that this question is subjective but I want to hear a variety of answers. Seth

  • WinForms / .Net interactive world map - how?

    - by FerretallicA
    In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which: Colour-codes each country depending on the number of CDs by artists in that country Allows clicking on each country to filter a list of CDs to only ones by artists in that country This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here: http://www.synergetechsolutions.com/blog/analytics-world-map-control Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?
