  • Display web page from another site in asp page.

    - by Daniel
    hi all, Our customer has a requirement to extend the functionality of their existing large government project. It is an ASP.NET 3.5 (recently upgraded from 2.0) project. The existing solution is quite a behemoth that is almost unmaintainable so they have decided that they want to provide the new functionality by hosting it on another website that is shown within the existing website. As to how this is best to be done I'm not quite sure right now and if there is any security issues preventing it or that need to be considered. Essentially the user would log on to the existing web site as normal and when cliicking on a certain link the page would load as normal with some kind of frame or control that has within it the contents of the page from the other site. IE. They do not want to simply redirect to the other site they want to show it embedded within the current one such that the existing menus etc are still available. I believe if information needed to be passed to the embedded page it would be done using query strings as I'm not sure if there is even another way to accomplish this. Can anyone give me some pointers on where to start at looking to implement this or any potential pitfalls I should be aware of. Thanks

  • [.NET] What's the point of MarshalByValue Object?

    - by smwikipedia
    Hi awesome! We know that MarshalByRef allow us to create an object in a different AppDomain and use a Proxy object to access it. And the behavior of that object is in a different context of the AppDomain where it actually lives in. Well this sounds faily reseaonable in the regard of isolation and safety. But why is there still MarshalByValue? MarshalByValue just leads to an newly deserialized object which is an exact copy of the object in a different AppDomain. If we need that object, why not just create it in the current AppDomain? Why bother to first create it in a different AppDomain and then get it back by MarshaoByValue? Many thanks.

  • VB.NET Abstract Property

    - by ElPresidente
    I have an abstract "GridBase" class with two types of derived classes "DetailGrid" and "HeaderGrid". Respectively, one is comprised of "DetailRow" objects and the other "HeaderRow" objects. Both of those inherit from a "RowBase" abstract class. What I am trying to do is the following: Public MustInherit Class GridBase Private pRows As List(Of RowBase) Public ReadOnly Property Rows As List(Of RowBase) Get Return pRows End Get End Property End Class Public Class DetailGrid Inherits GridBase End Class In this scenario, I want DetailGrid.Rows to return a list of DetailRow. I want HeaderRow.Rows to return a list of HeaderRow. Am I on the right track with this or should the Rows property not be included in the GridBase class?

  • .Net Removing all the first 0 of a string

    - by Melursus
    I got the following : 01.05.03 I need to convert that to 1.5.3 The problem is I cannot only trim the 0 because if I got : 01.05.10 I need to convert that to 1.5.10 So, what's the better way to solve that problem ? Regex ? If so, any regex example doing that ?

  • What .NET UnmanagedType is Unicode (UTF-16)?

    - by Pat
    I am packing bytes into a struct, and some of them correspond to a Unicode string. The following works fine for an ASCII string: [StructLayout(LayoutKind.Sequential)] private struct PacketBytes { [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 64)] public string MyString; } I assumed that I could do [StructLayout(LayoutKind.Sequential)] private struct PacketBytes { [MarshalAs(UnmanagedType.LPWStr, SizeConst = 32)] public string MyString; } to make it Unicode, but that didn't work. (Since this field is part of a struct with other fields, which I've omitted for clarity, I can't simply change the CharSet of the containing struct.) Any idea what I'm doing wrong?

  • Deleting items from datagrid (xml)

    - by Tonz
    Hello, I have a datagrid buttoncolumn which acts as delete buttons for my xml nodes. The elements are simply displayed in a boundcolumn, so there names get displayed. Each item generated gets a unique id (each time one is made id+++). My question his how can i remove a item (the entire element node with that certain id) when i click on one of the buttons in the bound column? <root> <element id="0"> <name>One</name> </element> <element id="1"> <name>Two</name> </element> </root> protected void dg_DeleteCommand(object sender, DataGridCommandEventArgs e) { XmlFunctions.Remove(index); }/*dg_DeleteCommand*/ (function on other class, where all my xml methods are written) public static void Remove(string index) { XmlDocument XMLDoc = new XmlDocument(); XMLDoc.Load(XMLFile); XPathNavigator nav = XMLDoc.CreateNavigator(); var node = nav.SelectSingleNode("/test/one[@id='" +???+ "']"); node.DeleteSelf(); XMLDoc.Save(XMLFile); } Edit: added datagrid <asp:View ID="viewDelete" runat="server"> <asp:DataGrid ID="dgDelete runat="server" AutoGenerateColumns="False" OnDeleteCommand="dg_DeleteCommand"> <Columns> <asp:BoundColumn DataField="name" HeaderText="names" /> <asp:ButtonColumn ButtonType="PushButton" Text="Delete" CommandName="Delete" ></asp:ButtonColumn> </Columns> </asp:DataGrid> </asp:View>

  • .net - invoke methods from classes from a certain namespace via reflection

    - by Kristian Hildebrandt
    SPL and PHP allows you to create objects on the fly from classes, that fulfill certain conditions, such as implementing certain interfaces and stuff like that. However, I would like to do something similar in c# and automatically create objects from all classes in a namespace and invoke a particular method from those classes that implement a certain interface. My experience developing desktop apps is very limited. I am not quite sure if I should use delegates to archive this or if reflection is really the way to go.

  • .NET Results Class

    - by pm_2
    I have a C# function that does some processing and needs to return figures about what it has processed, success, failure, etc. Can anyone tell me if there are any standard framework classes that will handle this (for example, number of records processed, number successful, failed, etc) ? Alternatively, can anyone say how they usually handle this? Is the best way to create a class, or to use out parameters?

  • Sorting Custom Objects with Parameter in VB.Net/C#

    - by Jeffrey Kern
    Let's say I have a custom object of Foo Is there anyway I can sort through a list of these objects, like list<of foo>.sort() and also be able to sort this list with a passable parameter. which will influence the sort? list<of foo>.sort(pValue) I'm guessing I'll need to define two separate sorts, but I am not sure. Thanks!

  • How to select a single object using Linq in vb.net

    - by Hucker
    I have done a lot of searching to what appears to be a simple LINQ problem but I can't figure out how to do grab an object out of a collection that has a specified minimum (or max value) without resorting to a sort like this: > dim customers= GetCustomers() > > dim youngest = (From c in customers > Order By c.age Ascending).ToList.First This (untested code) structure works fine with the exception that the entire customer array must be sorted and placed into a list for the only purpose of extracting the first value. That can't be the best way to get the minimum! Note that I want the whole c record in this case, not the minumum age of a customer that can be done like this (a typical example): > dim customers= GetCustomers() > > dim youngest = (From c in customers > Select c.age).Min Or even > dim customers= GetCustomers() > > dim youngest = (From c in customers > Select c).Min(Function(x) x.age) I can't for the life of me figure out how to get the whole object (or even the index) without resorting to the sort...

  • Can .NET AppDomains do this?

    - by Eloff
    I've spent hours reading up about AppDomains, but I'm not sure they work quite like I'm hoping. If I have two classes, Foo in AppDomain #1, Bar in AppDomain #2: App Domain #1 is the application. App Domain #2 is something like a plugin, and can be loaded and unloaded dynamically. AppDomain #2 wants to create Foo and use it. Foo uses lots of classes in AppDomain #1 internally. I don't want AppDomain #2 using object foo with reflection, I want it to use Foo foo, with all the static typing and compiled speed that goes with it. Can this be done considering that AppDomain #1, containing Foo, is never unloaded? If so, does any remoting take place here when using Foo? When I unload AppDomain #2, the type Foo is destroyed?

  • How to deploy updates to .NET website in cluster

    - by royappa
    We are operating a corporate web application on a load-balanced cluster that consists of two identical IIS servers talking to a single MSSQL database. To deploy updates I am using this primitive process: 1) Make a copy of the entire site folder (wwwroot\inetpub\whatever) on each IIS box 2) Download the updated, compiled files onto each IIS box from our development area 3) Shut down IIS both web servers 4) Copy the new and updated files into the wwwroot folder (overwriting any same files) 5) Then restart IIS on both machines When there are database changes involved there are a few other steps. The whole process is fairly quick but it is ugly and fraught with danger, so it has to be done with full concentration. I would like to just push one button to make it all happen. And I want a one-click rollback in case there is a problem (that's the reason I make the copy in step #1). I am looking for tools to manage and improve this process. If it also helped us maintain a changelog, that would be nice. Thanks.

  • VB.NET Incrementing Indexes

    - by Daniel
    Hello, I am having trouble incrementing the indexes of my list item properties. Here is the code. Dim i As Integer = 0 For x As Integer = 1 To list.Count / 19 database.ExecuteCommand("INSERT INTO Contacts VALUES ('" + _ list.Item(i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "', '" + _ list.Item(++i) + "')") Next The ++i does not increment at all in the parameters.
