    - by Sahat
    I am trying to decide which ASP.NET book should I buy. I've narrowed my choices down to these two books: ASP.NET 3.5 Unleashed (44 reviews / 4-stars) Beginning ASP.NET 3.5 WROX Programming (48 reviews / 4.5 stars) Which book would you recommend me and why? I am new to ASP.NET, but I am not entirely new to Web Development.

  • ASP.NET files necessary for development

    - by apollo-creed
    I am just getting started in ASP.NET and have some existing projects to maintain. I have read that ASP.NET projects include a folder called app_data, a code behind DLL, .sln project files, .proj files etc Which of these files are necessary for the continued development of a ASP.NET website? Also, are there others which are key to building ASP.NET applications?

  • Can I use reflection to find the bin/[Configuration] folder in ASP.NET instead of the asp temporary

    - by vfilby
    I have an ASP.NET website and I want to find the /bin/[Configuration] folder to use an external tool. When I use reflection to get calling assemblies location it returns something similar to: C:\Windows\Microsoft.NET\Framework\...\Temporary ASP.NET Files\a1388a5e\...\my.dll Since each dll has its own directory under the temp ASP.NET Files this fails for me. How can I get the location of the binary, not asp.net's temporary cache?

  • Is ASP.NET MVC 2 Bin-deployable?

    - by Nevada
    I know that ASP.NET MVC 1.0 is bin-deployable as explained in Phil Haack's article. Is ASP.NET MVC 2.0 also bin-deployable? Has anyone done this already that can point out potential pitfalls specific to version 2.0 if there are any? I would like to deploy a relatively simple ASP.NET MVC 2.0 onto a Windows 2008 Web server that does not have ASP.NET MVC 2.0 installed. It is running .NET Framework 3.5 Service Pack 1. Thanks!

  • Trying to create a .NET DLL to be used with Non-.NET Application

    - by Changeling
    I am trying to create a .NET DLL so I can use the cryptographic functions with my non .NET application. I have created a class library so far with this code: namespace AESEncryption { public class EncryptDecrypt { private static readonly byte[] optionalEntropy = { 0x21, 0x05, 0x07, 0x08, 0x27, 0x02, 0x23, 0x36, 0x45, 0x50 }; public interface IEncrypt { string Encrypt(string data, string filePath); }; public class EncryptDecryptInt:IEncrypt { public string Encrypt(string data, string filePath) { byte[] plainKey; try { // Read in the secret key from our cipher key store byte[] cipher = File.ReadAllBytes(filePath); plainKey = ProtectedData.Unprotect(cipher, optionalEntropy, DataProtectionScope.CurrentUser); // Convert our plaintext data into a byte array byte[] plainTextBytes = Encoding.ASCII.GetBytes(data); MemoryStream ms = new MemoryStream(); Rijndael alg = Rijndael.Create(); alg.Mode = CipherMode.CBC; alg.Key = plainKey; alg.IV = optionalEntropy; CryptoStream cs = new CryptoStream(ms, alg.CreateEncryptor(), CryptoStreamMode.Write); cs.Write(plainTextBytes, 0, plainTextBytes.Length); cs.Close(); byte[] encryptedData = ms.ToArray(); return Convert.ToString(encryptedData); } catch (Exception ex) { return ex.Message; } } } } } In my VC++ application, I am using the #import directive to import the TLB file created from the DLL, but the only available functions are _AESEncryption and LIB_AES etc I don't see the interface or the function Encrypt. When I try to instantiate so I can call the functions in my VC++ program, I use this code and get the following error: HRESULT hr = CoInitialize(NULL); IEncryptPtr pIEncrypt(__uuidof(EncryptDecryptInt)); error C2065: 'IEncryptPtr': undeclared identifier error C2146: syntax error : missing ';' before identifier 'pIEncrypt'

  • "too many automatic redirections were attempted" error message when using a httpWebRequest in .NET

    - by tooleb
    I am attempting to request a page like "http://www.google.com/?q=random" using the webrequest class in vb.net. we are behind a firewall, so we have to authenticate our requests. I have gotten past the authentication part by adding my credentials. But once that works it seems to go into a redirecting loop. Does anyone have an ideas, comments, suggetions why this is? Has anyone else experienced this problem?

    I am trying to create a desktop shortcut from vb.net code on a Windows 7 box (64 bit). The following code works on XP, but when run on Win7 I just get a message stating the App has stopped working: Imports IWshRuntimeLibrary Dim WshShell As WshShellClass = New WshShellClass Dim MyShortcut As IWshRuntimeLibrary.IWshShortcut ' The shortcut will be created on the desktop 'Win 7 MyShortcut = CType(WshShell.CreateShortcut("C:\Users\Public\Desktop\iexplore.lnk"), IWshRuntimeLibrary.IWshShortcut) 'MyShortcut = CType(WshShell.CreateShortcut("C:\Documents and Settings\All Users\Desktop\iexplore.lnk"), IWshRuntimeLibrary.IWshShortcut) MyShortcut.TargetPath = "C:\Program Files\Internet Explorer\iexplore.exe" 'Specify target app full path MyShortcut.Description = "IE" MyShortcut.Save() Any thoughts or better ways to create a shorcut from code on a Win7 box?

  • How to get selected values from a dynamically created DropDownList Array after PostBack (Button Click)

    - by user739280
    I have a CheckBoxList that contains Employee Names on a Wizard Step. When employees are selected and the active step is changed, the Wizard1_ActiveStepChanged function is called and it dynamically creates a DropDownList Array for each employee that is selected. Each DropDownList specifies a condition of the employee. The DropDownList is created properly. When the user clicks submit, the DropDownList array is deleted and no selected values can be pulled from the array. I understand this is an issue with the PostBack and can be fixed with ViewState, but I am trying to figure out what I can do to fix it. ViewState is enabled for the checkboxlist and the DropDownList. This is what I have in the body of my System.Web.UI.Page class private int empcount; private DropDownList[] DDL_Emp { get { return (DropDownList[])ViewState["DDL_Emp"]; } set { ViewState["DDL_Emp"] = value; } } The relevant code: protected void Wizard1_ActiveStepChanged(object sender, EventArgs e) { if (Request.QueryString["type"] == "Accident" && BulletedList1.Items.Count > 0) { this.empcount = 0; for (int i = 0; i < CBL_EmpInvolved.Items.Count; i++) { if (CBL_EmpInvolved.Items[i].Selected) { this.empcount++; } } if(this.empcount > 0) { this.DDL_Emp = new DropDownList[this.empcount]; for (int i = 0, j=0; i < CBL_EmpInvolved.Items.Count; i++) { if (CBL_EmpInvolved.Items[i].Selected) { List<ListItem> cond = new List<ListItem>(); cond.Add(new ListItem("Disabled", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Diseased - Fatality", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("On Treatment - Short Term Disability", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("On Treatment - Long Term Disability", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Back to Work", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Relocated", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Transferred", CBL_EmpInvolved.Items[i].Value)); this.DDL_Emp[j] = new DropDownList(); this.DDL_Emp[j].ID = "DD_LabCondition_" + CBL_EmpInvolved.Items[i].Value; this.DDL_Emp[j].EnableViewState = true; this.DDL_Emp[j].Visible = true; this.DDL_Emp[j].Items.AddRange(cond.ToArray()); this.DDL_Emp[j].Items.Insert(0, new ListItem("-- Select condition of employee: " + CBL_EmpInvolved.Items[i].Text, "")); PH_LabCondition.Controls.Add(this.DDL_Emp[j]); j++; } } PH_LabCondition.Visible = true; MV_LabCondition.Visible = true; Label1_ReportTitle.Text += "Control Count: " + PH_LabCondition.Controls.Count.ToString(); } MV_LabCondition.ActiveViewIndex = 1; MV_LostTime.ActiveViewIndex = 1; } } This code is giving me the following error now: Type 'System.Web.UI.WebControls.DropDownList' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable. I've tried changing buttons to images, playing with the AutoPostBack feature. I'm lost on how to get my dropdownlist array saved to the ViewState and accessing it after the postback.

  • UpdatePanel not working in IE or Chrome

    - by gevjen
    I have an updatepanel on my masterpage. Within the contentplace holder I have my update progress control. When a user clicks on the button I load some data into a gridview. This works perfectly in FireFox. User clicks the button, the loading image in my updateprogress fires and loads the gridview. When I test this in IE 6 or 7 or in Chrome. It does a full postback and the updateprogress is never shown. So the updatepanel doesnt seem to be working in these two browsers. Code is below. Again...it works perfect in FireFox. ***From Masterpage *** <asp:UpdatePanel ID="UpdatePanel" runat="server"> <contenttemplate> <asp:contentplaceholder id="holder" runat="server" /> </contenttemplate> </asp:UpdatePanel> **From aspx page **** <asp:UpdateProgress ID="UpdateProgress1" runat="server"> <ProgressTemplate> <img src="ajax-loader.gif" /> </ProgressTemplate> </asp:UpdateProgress>

  • Json.NET - How to serialize a class using custom resolver

    - by Mendy
    I want to serialize this class: public class CarDisplay { public string Name { get; set; } public string Brand { get; set; } public string Year { get; set; } public PictureDisplay[] Pictures { get; set; } } public class PictureDisplay { public int Id { get; set; } public string SecretKey { get; set; } public string AltText { get; set; } } To this Json test: { Name: "Name value", Brand: "Brand value", Year: "Year value", Pictures: ["url1", "url2", "url3"] } Note that each Car have an pictures array with only url string, instead of all the properties that Picture class have. I know that Json.NET have the notion of Custom Resolver, but I don't sure exactly how to use it.

  • Configure ASP.NET Application to Read Mapped Network Drive

    - by Bob
    Is it possible to configure an ASP.NET application under IIS 7 so it can read files stored in a mapped network drive? I'm not trying to serve up the contents of the drive. I simply need to read the contents within the ASP.NET application. I've searched the Web and haven't really found a solid answer. The questions in my mind are: Is this possible via configuration (i.e. I cannot modify the client code)? If so, what are the step by step instructions. If it is not possible, I'm fine with that. I already know UNC paths work but using them drastically changes the work flow. Thanks! Bobby

  • .NET and P2P - writing a P2P messenger

    - by brovar
    Hi there, Does anyone have any advice how to write such app? Or maybe knows some nice tutorial? I would like to use System.Net.PeerToPeer namespace, but everything I can find about it is MSDN which I can't read without getting mad. Or maybe using "old-school" TCP/IP would more efficient? I will appreciate every piece of advice. Every sample code I will shower with gold ;) And please, don't send me back to Google for I have searched for a long time for sth useful - maybe inaccurately but time is running out and I really need some help.

  • A checklist for fixing .NET applications to SQL Server timeout problems and improve execution time

    - by avgbody
    A checklist for improving execution time between .NET code and SQL Server. Anything from the basic to weird solutions is appreciated. Code: Change default timeout in command and connection by avgbody. Use stored procedure calls instead of inline sql statement by avgbody. Look for blocking/locking using Activity monitor by Jay Shepherd. SQL Server: Watch out for parameter sniffing in stored procedures by AlexCuse. Beware of dynamically growing the database by Martin Clarke. Use Profiler to find any queries/stored procedures taking longer then 100 milliseconds by BradO. Increase transaction timeout by avgbody. Convert dynamic stored procedures into static ones by avgbody. Check how busy the server is by Jay Shepherd.

  • How are .NET 4 GUIDs generated?

    - by mafutrct
    I am aware of the multitude of questions here as well as Raymond's excellent (as usual) post. However, since the algorithm to create GUIDs was changed apparently, I found it hard to get my hands on any up-to-date information. The MSDN seems to try and provide as few information as possible. What is known about how GUIDs are generated in .NET 4? What was changed, and how does it affect the security ("randomness") and integrity ("uniqueness")? One specific aspect I'm interested in: In v1, it seems to be about impossible to generate the same GUID on a single machine again since there was a timestamp and counter involved. In v4, this is no longer the case (I was told), so the chance to get the same GUID on a single machine ... increased?

  • .NET 4.0 project reference 2.0 assembly

    - by jamone
    I have a project in which I'd like to use some of the .NET 4.0 features but a core requirement is that I can use the System.Data.SQLite framework which is compiled against 2.X. I see mention of this being possible such as the accepted answer here but I don't see how to actually achieve this. When I just try and run my 4.0 project while referencing the 2.X assembly I get: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. What "additional configuration" is necessary?

  • ODP.NET Code Example Critque or best practices

    - by andrewWinn
    I currently have a DataAccess Layer in Vb.Net. I am not too happy with my implementation of both my ExecuteQuery (as DataSet) and ExecuteNonQuery functions.

  • Disable caching on a specific Classic ASP page

    - by David Brunelle
    Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in Classic ASP which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or Classic ASP) to prevent that from happening? Or is it in IIS that we must set this up? Thanks,

  • How can we expose a .NET public const to COM interop

    - by JulienC
    For historical reasons, we need to expose string constants in .NET through COM interface. We managed to expose ENUM but we can't find a way to expose string const. We try the following code : <ComClass(ComClass1.ClassId, ComClass1.InterfaceId, ComClass1.EventsId)> _ Public Class ComClass1 #Region "COM GUIDs" ' These GUIDs provide the COM identity for this class ' and its COM interfaces. If you change them, existing ' clients will no longer be able to access the class. Public Const ClassId As String = "608c6545-977e-4260-a3cf-11545c82906a" Public Const InterfaceId As String = "12b8a6c7-e7f6-4022-becd-2efd8b3a756e" Public Const EventsId As String = "05a2856f-d877-4673-8ea8-20f5a9f268d5" #End Region ' A creatable COM class must have a Public Sub New() ' with no parameters, otherwise, the class will not be ' registered in the COM registry and cannot be created ' via CreateObject. Public Sub New() MyBase.New() End Sub Public Const chaine As String = "TEST" Public Sub Method() End Sub End Class But when we look on the OLE object viewer, we only see the method. See ScreenShot: screenshot of OLE viewer Anyone have an idea ? Thanks,

  • UpdatePanel and ModalPopup Extender

    I have my form designed as <asp:Panel runat="server" Id="xyz"> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> 'Gridview with edit/delete - opens detailsview(edit template) with data for editing </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional"> <ContentTemplate> 'Hyperlink to open detailsview(insert template) for inserting records </ContentTemplate> </asp:UpdatePanel> </asp:Panel> <asp:Panel runat="server" Id="xyz1"> 'Ajax modal popup extender control </asp:Panel> It works perfectly when i click update, insert alternately, but when i click insert hyperlink (which is outside gridview) and close/cancel popup without any insert and then again click insert it doesn't call insert_onclick event. It works if i click some other button and click this button. What could be causing this issue and how can i solve it?

  • Strange IIS/Asp.net Exception Message

    - by Element
    I have a standard asp.net 2.0 application running on IIS 6. I have noticed some strange exception messages in the logs. They seem to be caused by random spam bots trying to submit forms. They are strange because the request string is huge and all the exception details in the event manager are messed up, they have been replaced with %21,%22, etc.. as seen in the screen shot. Is this some kind of exploit or just a bug in the asp.net exception handler/logger ? UPDATE: I traced the requests that are causing this strange log event to a bug in IE8 that causes it to request scriptresource.axd?d={html from page} as described in these links: MS Connect SO - Invalid Webresource.axd SO - IE8 Dropping Memory Pages I am still not sure why these requests would break the IIS log event like seen above, they are just long strings of jiberish being sent to the server, maybe someone reading this can shed some light on it.
