  • How do I resolve the config error which states a machine to application error

    - by waterfalrain
    I imported a website made in visual studio express 2008 to visual studio express 2010. When I run the home page I get the following error: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS." When I looked up the meaning of this on Google I read their needed to be a change to the configuration of the virtual directory. Another suggestion was to change the web config files . T Were these suggestions correct? If so how do I emplement them so that I can view these website pages on my local machine.

  • Not possible to load DropDownList on FormView from code behind??

    - by tbone
    I have a UserControl, containing a FormView, containing a DropDownList. The FormView is bound to a data control. Like so: <asp:FormView ID="frmEdit" DataKeyNames="MetricCode" runat="server" DefaultMode="Edit" DataSourceID="llbDataSource" Cellpadding="0" > <EditItemTemplate> <asp:DropDownList ID="ParentMetricCode" runat="server" SelectedValue='<%# Bind("ParentMetricCode") %>' /> etc, etc I am trying to populate the DropDownList from the codebehind. If this was not contained in a FormView, I would normally just do it in the Page_Load event. However, that does not work within a FormView, as as soon as I try to do it, accessing the dropdownlist in code, ie: theListcontrol = CType(formView.FindControl(listControlName), System.Web.UI.WebControls.ListControl) ...the data binding mechansim of the FormView is invoked, which, of course, tries to bind the DropDownList to the underlying datasource, causing a *'ParentMetricCode' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value * error, since the DropDownList has not yet been populated. I tried performing the load in the DataBinding() event of the FormView, but then: theListcontrol = CType(formView.FindControl(listControlName), System.Web.UI.WebControls.ListControl) ...fails, as the FormView.Controls.Count = 0 at that point. Is this impossible? (I do not want to have to use a secondary ObjectDataSource to bind the dropdownlist to)

  • Which cross threading invoke function is better for a control that is inherited?

    - by Stevoni
    I have a relatively simple question regarding the best way to call the DataGridView.Rows.Add function when it is inherited into the current control. Which is the best way to make the call to the inherited control? Call it directly in the invoke or call it using recursive-like function? They both seem to produce the same result, a row gets added and the quantity is returned, but which is the most efficient? The delegate: Private Delegate Function ReturnDelegate() As Object The two ways are: A) Private Overloads Function AddRow() As Integer If InvokeRequired Then Return CInt(Invoke(New ReturnDelegate(AddressOf AddRow))) Else Return Rows.Add() End If End Function Or B) Private Function RowsAdd() As Integer If Me.InvokeRequired Then Return CInt(Me.Invoke(New ReturnDelegate(AddressOf MyBase.Rows.Add))) Else Return MyBase.Rows.Add End If End Function

  • Random String Generator creates same string on multiple calls

    - by rockinthesixstring
    Hi there. I've build a random string generator but I'm having a problem whereby if I call the function multiple times say in a Page_Load method, the function returns the same string twice. here's the code ''' <summary>' ''' Generates a Random String' ''' </summary>' ''' <param name="n">number of characters the method should generate</param>' ''' <param name="UseSpecial">should the method include special characters? IE: # ,$, !, etc.</param>' ''' <param name="SpecialOnly">should the method include only the special characters and excludes alpha numeric</param>' ''' <returns>a random string n characters long</returns>' Public Function GenerateRandom(ByVal n As Integer, Optional ByVal UseSpecial As Boolean = True, Optional ByVal SpecialOnly As Boolean = False) As String Dim chars As String() ' a character array to use when generating a random string' Dim ichars As Integer = 74 'number of characters to use out of the chars string' Dim schars As Integer = 0 ' number of characters to skip out of the characters string' chars = { _ "A", "B", "C", "D", "E", "F", _ "G", "H", "I", "J", "K", "L", _ "M", "N", "O", "P", "Q", "R", _ "S", "T", "U", "V", "W", "X", _ "Y", "Z", "0", "1", "2", "3", _ "4", "5", "6", "7", "8", "9", _ "a", "b", "c", "d", "e", "f", _ "g", "h", "i", "j", "k", "l", _ "m", "n", "o", "p", "q", "r", _ "s", "t", "u", "v", "w", "x", _ "y", "z", "!", "@", "#", "$", _ "%", "^", "&", "*", "(", ")", _ "-", "+"} If Not UseSpecial Then ichars = 62 ' only use the alpha numeric characters out of "char"' If SpecialOnly Then schars = 62 : ichars = 74 ' skip the alpha numeric characters out of "char"' Dim rnd As New Random() Dim random As String = String.Empty Dim i As Integer = 0 While i < n random += chars(rnd.[Next](schars, ichars)) System.Math.Max(System.Threading.Interlocked.Increment(i), i - 1) End While rnd = Nothing Return random End Function but if I call something like this Dim str1 As String = GenerateRandom(5) Dim str2 As String = GenerateRandom(5) the response will be something like this g*3Jq g*3Jq and the second time I call it, it will be 3QM0$ 3QM0$ What am I missing? I'd like every random string to be generated as unique.

  • Database not updating after UPDATE SQL statement in ASP.net

    - by Ronnie
    I currently have a problem attepting to update a record within my database. I have a webpage that displays in text boxes a users details, these details are taken from the session upon login. The aim is to update the details when the user overwrites the current text in the text boxes. I have a function that runs when the user clicks the 'Save Details' button and it appears to work, as i have tested for number of rows affected and it outputs 1. However, when checking the database, the record has not been updated and I am unsure as to why. I've have checked the SQL statement that is being processed by displaying it as a label and it looks as so: UPDATE [users] SET [email]=@email, [firstname]=@firstname, [lastname]=@lastname, [promo]=@promo WHERE ([users].[user_id] = 16) The function and other relevant code is: Sub Button1_Click(sender As Object, e As EventArgs) changeDetails(emailBox.text, firstBox.text, lastBox.text, promoBox.text) End Sub Function changeDetails(ByVal email As String, ByVal firstname As String, ByVal lastname As String, ByVal promo As String) As Integer Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0; Ole DB Services=-4; Data Source=C:\Documents an"& _ "d Settings\Paul Jarratt\My Documents\ticketoffice\datab\ticketoffice.mdb" Dim dbConnection As System.Data.IDbConnection = New System.Data.OleDb.OleDbConnection(connectionString) Dim queryString As String = "UPDATE [users] SET [email]=@email, [firstname]=@firstname, [lastname]=@lastname, "& _ "[promo]=@promo WHERE ([users].[user_id] = " + session.contents.item("ID") + ")" Dim dbCommand As System.Data.IDbCommand = New System.Data.OleDb.OleDbCommand dbCommand.CommandText = queryString dbCommand.Connection = dbConnection Dim dbParam_email As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_email.ParameterName = "@email" dbParam_email.Value = email dbParam_email.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_email) Dim dbParam_firstname As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_firstname.ParameterName = "@firstname" dbParam_firstname.Value = firstname dbParam_firstname.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_firstname) Dim dbParam_lastname As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_lastname.ParameterName = "@lastname" dbParam_lastname.Value = lastname dbParam_lastname.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_lastname) Dim dbParam_promo As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_promo.ParameterName = "@promo" dbParam_promo.Value = promo dbParam_promo.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_promo) Dim rowsAffected As Integer = 0 dbConnection.Open Try rowsAffected = dbCommand.ExecuteNonQuery Finally dbConnection.Close End Try labelTest.text = rowsAffected.ToString() if rowsAffected = 1 then labelSuccess.text = "* Your details have been updated and saved" else labelError.text = "* Your details could not be updated" end if End Function Any help would be greatly appreciated.

  • When should I implement IDisposable?

    - by Bobby
    What is the best practice for when to implement IDisposable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

  • QT vs. Net - REAL comparisons for R.A.D. projects

    - by Pirate for Profit
    Man in all these Qt vs. .NET discussions 90% these people argue about the dumbest crap. Trying to get a real comparison chart here, because I know a little about both frameworks but I don't know everything. I believe Qt and .NET both have strengths and weaknesses. This is to make a comparison that highlights these so people can make more informed decisions before embarking on a project, in the spirit of R.A.D. Event Handling In Qt the event handling system is very simple. You just emit signals when something cool happens and then catch them in slots. ie. // run some calculations, then emit valueChanged(30, false, 20.2); and then catching it, any object can make a slot to recieve that message easily void MyObj::valueChanged(int percent, bool ok, float timeRemaining). It's easy to "block" an event or "disconnect" when needed, and works seamlessly across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, void valueChanged(object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET anonymous delegates are the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down for the simplest yet still flexible event handling system ever i m o. Plugins and such I do love some of the ease of C# compared to C++, as well as .NET's assembly architecture, even though it leads to a bunch of .dll's (there's ways to combine everything into a single exe though). That is a big bonus for modular projects, which are a PITA to import stuff in C++ as far as RAD is concerned. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. QConcurrent is the simplest threading mechanism I've ever played with. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? Doesn't the just-in-time compiler make native code that is pretty good, like and that only happens the first time the program is run? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

  • .NET remoting manual configuration

    - by Quandary
    Question: In .NET remoting, I configure the client like this from a config file RemotingConfiguration.Configure("AsyncRemoteAPIclient.exe.config", False) Dim obj As New RemoteAPI.ServiceClass() (with this AsyncRemoteAPIclient.exe.config) <system.runtime.remoting> <application> <client> <wellknown type="RemoteAPI.ServiceClass, ServiceClass" url="http://localhost:8080/ServiceClass.rem" /> </client> <channels> <channel ref="http" port="0" /> </channels> </application> But when I replace the config file with manual configuration with the below code, it stops working, and starts complaining "ServiceClass or dependency not found". Dim chan As New System.Runtime.Remoting.Channels.Http.HttpChannel(0) System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(chan, False) ' Create an instance of the remote object Dim obj As RemoteAPI.ServiceClass obj = CType(Activator.GetObject(GetType(RemoteAPI.ServiceClass), "http://localhost:8080/ServiceClass.rem"), RemoteAPI.ServiceClass) What's wrong ?
