  • Convert webpage to image from ASP.NET

    - by Nissan Fan
    I would like to create a function in C# that takes a specific webpage and coverts it to a JPG image from within ASP.NET. I don't want to do this via a third party or thumbnail service as I need the full image. I assume I would need to somehow leverage the webbrowser control from within ASP.NET but I just can't see where to get started. Does anyone have examples?

    Hello, I have developed an ASP.NET web application that I'm working on putting the finishing touches on. To assist with this, I have been using YSlow.

How do I configure entity tags on components within an ASP.NET page? Thank you!

  • How to add a title attribute to every option of an ASP.NET DropDownList

    - by zuallauz
    I'm working on an older ASP.NET project (not MVC I don't think) and one of the features they require is to view a description of an item when they hover over that item in a dropdown list. This can be simply done with HTML using the following code and making use of title text: <select> <option value="1" title="Option 1 Desc">Option 1</option> <option value="2" title="Option 2 Desc">Option 2</option> <option value="3" title="Option 3 Desc">Option 3</option> </select> Ok so how do I do this using ASP.NET DropDownList control? I have the following code: <asp:DropDownList ID="DropDownListLocation" runat="server" AutoPostBack="true" OnSelectedIndexChanged="DropDownListLocation_OnSelectedIndexChanged" CssClass="editorFieldServerControl" ClientIDMode="Static"></asp:DropDownList> And in the 'code behind' page: private void PopulateFacilityDropdown(List<FacilityAvailableByLocation> facilities, int? selectedID) { DropDownListFacility.DataSource = facilities; DropDownListFacility.DataTextField = "FacilityName"; DropDownListFacility.DataValueField = "FacilityID"; DropDownListFacility.DataBind(); DropDownListFacility.Items.Insert(0, new System.Web.UI.WebControls.ListItem("", "")); if (selectedID.HasValue && selectedID.Value > 0) DropDownListFacility.SelectedIndex = facilities.FindIndex(b => b.FacilityID == selectedID.Value); else DropDownListFacility.SelectedIndex = 0; } } Basically each facility in the list of facilities there has properties for an ID, Name, Description that I can get out. I just want to be able to put a title attribute on each <option> that gets rendered and put the description into it. Either that or be able to add a custom attribute like 'data-description' to each <option> tag then I can add the title into each option tag myself using a bit of jQuery which is easy enough. I miss the days where you could just loop through a list and output the custom dropdown code manually. Any ideas? Many thanks

  • Windows 2012/IIS 8 + ASP.NET MVC Applicaiton 403.14 (Forbidden) - The Web server is configured to not list the contents

    - by WiredPrairie
    I have a very simple MVC 4 application I'm trying to deploy to a Windows 2012 server. Inconsistently, when navigating to the root of the web application (http://localhost/app), it returns a 403.14-Forbidden: Detailed Error Information: Module: DirectoryListingModule Notification: ExecuteRequestHandler Handler: StaticFile Error Code: 0x00000000 Requested URL: http://localhost:80/test1/ Physical Path: c:\apps\test1\ Logon Method: Negotiate The web application is: Is a very vanilla VS2012 MVC4 Intranet template -- with only a tweak to a label to prove things were working. runs in an Integrated v4.0 application pool setup to use Windows authentication application pool has a custom AD Identity assigned (so it can gain access to a SQL server) application pool identity has read permissions in the c:\apps\test1 folder in which it is running It's an MVC4 application, targeting .NET 4.0 currently -There's no default document in an MVC4 application (like a default.aspx), as there shouldn't need to be one. I don't want to enable directory listings (as that's not the real error). Installed: Roles / Web Server (IIS) / Appliation Development / (.NET 4.5 Extensibility, Application Initialization, ASP.NET 4.5, ISAP Extensions, ISAPI Filters, WebSocket Protocol) Works locally on my machine in IISExpress on Windows 8 Has configured in web.config: <modules runAllManagedModulesForAllRequests="true" /> is set to precompiled during publish When I change the precompiled option to false, the web application does not fail (in my testing at least, it seems to work consistently). The reason I say it's inconsistent is that I've seen it work, then I've published, and the error returns. I can't find a pattern to the issue (and right now, I haven't been able to get it work again, at all). The 403 is returned from a local or remote web browser. I've had trouble finding a solution that isn't intended for older versions of Windows (like suggestions to reinstall ASP.NET which won't work on Windows 2012). I really don't know what else to try.

  • Exchange 2003 SP2 and Windows Server 2008 R2 Domain Controllers

    - by Brian
    I'm looking at adding two Windows Server 2008 R2 Domain Controllers into our Windows Server 2003 domain to support our Exchange 2003 SP2 server and replace a retiring Windows Server 2003 Server. Our Domain and Forest functional levels are currently Windows Server 2003, which supports domain controller operating systems (Windows Server 2008 R2, Windows Server 2008 and Windows Server 2003) according to the "Appendix of Functional Level Features" on Technet . So there should not be an issue other than running adprep /forestprep and adprep /domain.... right!? But, according to the Exchange Server Supportability Matrix, Windows Server 2008 R2 Active Directory Servers are not supported as global catalog servers or domain controllers in a Exchange 2003 SP2 environment!!!??? This was a shock to me... How can Windows Server 2008 R2 be a DC for a Windows Server 2003 domain and forest, but not communicate with an Exchange 2003 SP2 server? Hopefully, I'm not the first to see this issue (or maybe I am), but I know a lot of Exchange 2003 admins will not be happy if there is not a work around... or is Microsoft trying to push everyone automatically to Exchange 2010...

  • Can not join additional domain controllers

    - by Hosm
    Hi all, I had a dead PDC and another not so synced domain controller for my domain. using comments here link now the so called secondary domain controller has seized domain controls and I can verify it from dsa.msc that it is a domain controller. I set up another domain controller (win2003SRV) and about to promote an AD on it as a domain controller for my domain. When I try to join the new domain controller to the domain I face DNS problem. here is some more detail DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain DOMNAME.A.B: The query was for the SRV record for _ldap._tcp.dc._msdcs.DOMNAME.A.B The following domain controllers were identified by the query: update.DOMNAME.A.B Common causes of this error include: - Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses. - Domain controllers registered in DNS are not connected to the network or are not running. For information about correcting this problem, click Help. it is worth noting that update.DOMNAME.A.B is the current domain controller to which I'd like to add another controller named PDC.DOMNAME.A.B Ip address of update.DOMNAME.A.B is 192.168.200.1 and for pdc.DOMNAME.A.B is 192.168.200.100 querying DNS on both machine return correct results. Any idea?

  • None of usb-controllers are working after a crash

    - by Cray
    So I have a GA-p35-DS4 mboard with a Q6600, running windows7-x64. After a random crash with a bluescreen (not caused by anything particular as I recall), none of the usb-controllers are working. (And none of the devices connected to those usb ports). All the controllers are showed up in the device manager, but every one has a warning-icon (as they are not functioning properly). The windows identifies them correctly, it shows exactly the model of each controller, and it says that the driver is installed. Now, when I try to reinstall the driver (Update driver menu item in the device manager), it tries to find it, finds the driver, but quits saying that the driver was found but could not be installed. Additionally, it displays "This operation requires an interactive window station", whatever that means... Now get this, the same thing happens with a new pci-usb controller card! It is found (actually each time the machine starts, it is found as new hardware), but trying to install drivers leads nowhere, I am getting the same message about an interactive window station. (tried to install drivers from the acoompanying CD) I have tried deleting those devices from device manager and let windows find them again, but that leads to same results. None of the ports on this extension card work either. This should not be a hardware problem, a usb keyboard connected to the builtin usb controller works in bios, and even in another OS running the same computer (old xp installation) What to do? Will I have to reinstall? Can deleting infcache.1 help? Is there some way to let windows remove all old drivers and try to find all hardware again, this time only looking for drivers on a windows install disk or something?

  • ASP.NET Ajax.BeginForm Posts Even If Validation Fails

    - by Acoustic
    I'm just overlooking something simple... but my form, which is an Ajax form, always submits even if the validation fails. I'm not using jQuery validation, just the standard .NET MVC validation. Each of the field failing get show the validation message and highlight the field, but the form just submits anyway. Is there an OnBegin script I can call to prevent the form from submitting if there are errors? Thanks for the help! Ajax.BeginForm("EditUserProfile", new AjaxOptions { HttpMethod = "Post", OnComplete = ToggleViews", UpdateTargetId ="userProfileContainer" })

  • JavaScript Intellisense with Telerik in ASP.NET Master Page Project with VS 2010

    - by Otto Neff
    Today I was looking for a solution to get finally the JScript/Javascript/jQuery Intellisense Featureworking with my ASP.Net Webform Project to work. I found some good articles: - JScript IntelliSense Overview- JScript IntelliSense: A Reference for the “Reference” Tag- Enabling JavaScript intellisense in VS.NET 2010 to work with SharePoint 2010- Rich IntelliSense for jQueryBUT, all of suggested solutions did not work right with my Master Page based Visual Studio 2010 Solution.Only with physical Javascript Files (Telerik includes certain Javascript Files like jQuery as Ressource) or/andconfigure always a new ASP.NET Scriptmanager / RadScriptManager on every page derived from the Master Page, wasn't exactly what I was looking for. So I came up with the following simple Solution, to Trick VS2010and still have the Project running with multiple runat="server" Scriptmanagers. In short:- New ASP.NET control derived from ScriptManager with emtpy overwritten OnInit() to use it as emtpy wrapper for VS2010. In detail:New RadScriptManager Classusing System; using System.Collections.Generic; using System.Linq; using System.Web; using Telerik.Web.UI; namespace IntellisenseJavascript.Controls { public class IntelliJS : RadScriptManager { protected override void OnInit(EventArgs e) { } protected override void OnPreRender(EventArgs e) { } protected override void OnLoad(EventArgs e) { } protected override void Render(System.Web.UI.HtmlTextWriter writer) { } public override void RenderControl(System.Web.UI.HtmlTextWriter writer) { } } } web.config<configuration> ... <system.web> ... <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2011.3.1115.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/> <add tagPrefix="VSFix" namespace="IntellisenseJavascript.Controls" assembly="IntellisenseJavascript"/> </controls> </pages> ...

  • .NET WF4: Should it be in the middle of everything?

    - by stimpy77
    I am aware that WF4 (Windows Workflow 4.0, part of .NET 4.0) is a significant rework and redesign of WF3, where much of what made WF3 a poor technology choice has been cleaned up in WF4. For example, as far as I can tell, WF4 (Windows Workflow 4.0) activities are more or less testable with [TestMethod] and mocking. This among other things, like improved performance, has grabbed my attention about the technology again, whereas I had previously pooh-poohed WF3. I'm working on a new architecture for essentially an n-tier collaborative application (not enterprise-class, just a smallish project with potential to grow significantly) where I'm already trying to discipline myself to use IoC and, to some extent, TDD, and I'm wondering, in general terms, whether it is wiser to just hand-code workflow logic or if I should delve into learning and integrating WF4 so that WF becomes literally the controller of the entire application, i.e. the practical C in "MVC" (not ASP.NET MVC but rather the pattern). So should workflow activities in WF4 be the primary controller for a highly expandable/growable web-based collaborative application? Or am I asking entirely the wrong question? This is a vague question, I'm sure, so abstract answers are as welcome as specific ones.
