I know this may be a simple answer or at least to most people but I'm not getting anywhere when attempting this on my own or through the various resources I have looked up.
Here is my issue:
I am using ASP/VB.NET to build this integration. Visual Studio 2008. I previously had asked a question on API Integration on here and utilized that information to successfully perform the next steps. As this API is written differently I may not be grasping the appropriate functions correctly.
A company has given me several addresses for .ASMX portals. I add these into my service references. I can successfully see objects in my object browser and see all the procedures, etc., but further from here I'm unable to correctly use any objects. I attempted to replicate the integration based on my last API question and advice: Connecting to an API offered by a Company. When I'm attempting to use an object or simply relate a field to something on my script I continually get an error.
For example:
Dim A as New API.AddFunction
A.AccountNo = "123"
When running the page:
Object reference not set to an instance of an object.
Here is only one .ASMX I was given. I cannot release any more, until I receive permission to do so from the provider, I apologize.
[URL]
Anyhow, the root of my question is really how do I correctly interface with this API? What information do responders require so I can clarify this question more?
I have been given some basic documentation of the RazorGator REST API and need to incorporate it into an ASP.NET 3.5 site. I've created my class file to call the API which contains my WebRequest.Create ("URL TO API"). How do I then make the output available so that it can be consumed by other pages? That is, the tickets.aspx page needs to obtain the output results of this API call. What constructs should I use to make this available in tickets.aspx?
Edit Here's the code I've written thus far:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.IO; using System.Net; using System.Text; namespace SeatEater.Web.UI.search { public class RazorGatorService { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.razorgator.com/ticketservice/ticets.xml?blahblah") as HttpWebRequest ; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream receiveStream = response.GetResponseStream(); StreamReader readStream = new StreamReader(receiveStream, encode); response.close(); readStream.close(); } }
I receive the error message:
A field initializer cannot reference the nonstatic field, method, or property 'field'
in the second line of the above codeblock. I'm very new to using HttpWebRequest and HttpWebResponse. Can you advise me as to how to rectify the error message I'm receiving?
asp.net 4.0I'm trying to utilize a webservice but is not 100% sure how to do the coding. I've added reference to the web service in the project.The webservice have this class:sendCompletedEventArgs(object[], System.Exception, bool, object) And this delegate:sendCompletedEventHandler(object, sendCompletedEventArgs, System.AsyncCallback, object)This delegate have BeginInvoke(object, sendCompletedEventArgs, System.AsyncCallback, object) and EndInvoke()any suggestions how to utilize this webservice is most welcome?
I am trying to utilize an AnimationExtender that will fade in an asp:LinkButton. My page includes 4 user controls that each load information at different intervals. What I am wanting to do is fade in the asp:LinkButton after the last user control has loaded. I have tried using <OnLoad> but the fade in occurs while the user controls are still loading. I have also tried wrapping the user controls in a panel (seen below), using the panel as the TargetControlID of the AnimationExtender. My end goal here is pretty simple: The user should not see the asp:LinkButton until after the page (including the 4 user controls) has loaded.
We are trying to remove the global.asax from our many web applications in favor of HttpModules that are in a common code base. This works really well for many application events such as BeginRequest and PostAuthentication, but there is no Application Start event exposed in the HttpModule.
I can think of a couple of smelly ways to overcome this deficit. For example, I can probably do this:
protected virtual void BeginRequest(object sender, EventArgs e) { Log.Debug("Entered BeginRequest..."); var app = HttpContext.Current.Application; var hasBeenSet app["HasBeenExecuted"] == null ? false : true; if(!hasBeenSet) { app.Lock(); // ... do app level code app.Add("HasBeenExecuted", true); app.Unlock(); } // do regular begin request stuff ... }
But this just doesn't smell well to me.
What is the best way to invoke some application begin logic without having a global.asax?
I've been working on the Music Store tutorial and I cannot get my site to utilize the Album.ascx view template. For now I'll give the short version of my problem because I'm thinking I'm just missing something obvious. I'll provide further elaboration/code if needed. I'm stuck on Part 4. From my understanding, after adding the Shared folder and adding the Album.ascx partial file, I should be seeing this after browsing to the Store Manager Index and selecting an album to edit: Instead, I'm still seeing this: I even copied the code from the dowloaded solution for the Edit.aspx and Album.ascx files. It seems my project is completely disregarding my View Template.
There is one page which is actually a streaming to The Axis IP camera which spits MJPEG output.It requires user to log in with the user name/password promp on browser .I am using this stream to show video directly on a web page.It shows video correctly but asks user to provide correct user name and password set for the camera,I tried to logging in to this camera on server side using HTTP requests and then I realized I authenticated server request not the browser the end user is using.
So what I want is a method server side or client side, that can allow me to log-in to camera automatically when my end-users visit this page.I am using asp.net with c# 2005
I need to style the asp:Menu so the navigation buttons have rounded corners.
I have a javascript-based navigation menu (not asp.net) that uses images to simulate rounded corner navigation. However, I think I have to use an asp:Menu for my asp.net 4 website instead of a static page navigation menu.
I also plan to use Dynamic Data on multiple tabbed pages.
I need to utilize about 30 different database values from within a repeater ItemDataBound Event and I am wondering if there is a better way to do it. I am currently exposing them by doing something like this 30 times:
[Code]....
Rather than making 30 declarations, is there a way I can make them all available as short variable names? The variable name could be the same as the field name.
I have an ASP.NET project using a COM dll. When I load the site, I login without a problem and I can browse the site fine as long as I don't go to a page which uses the COM library. When I go to a page which uses the COM library to get data from a database, the page loads fine. The problem comes when I navigate away form this page. For some reason I am sent back to the login page as if the initial session was dropped. If I take away the component on the page which displays the data which the library retrieves, I can navigate away from the page, so it is definitely the call to the library that kills the session. Does anyone have any idea why this could happen?
I work with many diverse technologies, and don't possess the time to evaluate every single UI framework, so I'd appreciate hearing other coders' experiences with various frameworks.
The stuff I've worked with so far (and my perceptions):
WinForms: DevExpress (love the looks, hate the API and bloat), Krypton (free!, looks good, but limited), Telerik (don't like the looks)WPF: have only used WPF Themes pack. Asp.Net: Telerik MVC Controls (love it), jQuery UI (looks great)
I have two 3rd party unmanaged c++ dll and one C++ project which uses these dlls. In my asp.net project i added c++ project as reference but in runtime it fails with that error:
Exception from HRESULT: 0x8007007E
Visual studio puts c++ project's dll into /bin folder auto. Even if i put other dlls into bin folder, it fails.
I have a java applet, how can I deploy this java applet in the asp.net page, so I can use the java applet in the web page?, I hope that one expert can give me a good walk through.
I found a great control with example here for mvc It fulfills all my requirement but the problem is that it uses a js tree dll. Should I go on and used that example in my application? Do you people refrain from using 3rd party free dll in applications? How will I tell that it will not expire or not cause problem later on Forgive me if this is inappropriate question but thx in advance for any appropiate reply on this topic. just trying to get the point of view of you people on this
The Scenario: I have a situation where I need to pass some session variables to an ASPX page, inside a DNN module. This page is then transferred to Winnovative's PDF publishing component's in the form of a byte array. The component returns a PDF document in the result, furthermore that PDF document is then emailed to the customer.
The Problem: The session gets expired when the ASPX page is called (hosted as a part of DNN web project on IIS) to pass it to Winnovative. It was noticed that the session expired when ever I request the page (by any means) and a new session on that page is created.
Is there any workaround (without involving a database) that I can access those session variables (it is a dataset) from that particular ASP.NET page?
I am working on an add-on component that needs to play nice with other similar add-ons. There is a 3rd party component that decided to implement the functionality a little differently than the default. What I am trying to do is call an overload of a method that only the 3rd party component has, like this:
Select Case True Case TypeOf provider Is 3rdParty.Provider result = DirectCast(provider, 3rdParty.Provider).GetNames(method, True) Case Else result = provider.GetNames(method) End Select
Unfortunately, the DLL that contains 3rdParty.Provider is optional, so this code will give compile errors if it is not present. How can I accomplish the same thing but make it safe to run whether the 3rdParty.Provider.dll is present or not?
the situation is quite complex ( and my english very basic) but let's try to explain:
i'm developing a Asp.net web service calling a method from an external dll. This external dll calls some method from other .net dlls. So we have:
Asp.net WS ----> External.dll ----> other.NEt.Dll(---> other .netdll)
You have to know that the external dll uses a path ( given by an initialize method) to resolve its internal reference. In conclusion i have a web application with an added reference to my External.dll and a fully trusted path ( c:EXTERNAL ) full of all the .net dlls needed by external.dll. Looking around i've found this code to add to the application_START:
Dim path As String = String.Concat(System.Environment.GetEnvironmentVariable("PATH"), ";", "c:EXTERNAL) System.Environment.SetEnvironmentVariable("PATH", path, EnvironmentVariableTarget.Machine)
this add my c:EXTERNAL to global environment PATH. With this configuration running from the Visual Studio development server i get no error and it all works correctly. When i publish the application on my local IIS server it gives various errors: At first the result is something like:
Failure reading <Myobject> control of <(static)> type Unable to create <myobject> object (<C:(WRONGPATH) eeded.net.dll> assembly)
To resolve this i've tried to add the needed .net dlls to the /bin of my application in wwwroot but the result is something like:
Failure reading <MyType> control of <Myobject> type Error returned by .NET Framework: System.ArgumentException: Un oggetto di tipo 'ComNet.BaseControl.LoginDisplayLayout' non può essere convertito nel tipo 'ComNet.BaseControl.LoginDisplayLayout'. in System.RuntimeType.CheckValue(Object value, Binder binder, CultureInfo culture, BindingFlags invokeAttr) in System.Reflection.MethodBase.CheckArguments(Object[] parameters, Binder binder, BindingFlags invokeAttr, CultureInfo culture, Signature sig) in System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) in System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) in System.Reflection.RuntimePropertyInfo.SetValue(Object obj, Object value, BindingFlags invokeAttr, Binder binder, Object[] index, CultureInfo culture) in System.Reflection.RuntimePropertyInfo.SetValue(Object obj, Object value, Object[] index) in CDotNetType.bSetProperty(CDotNetType* , Object gcrObj, SByte* pszNom, CSLevel* pclPile, Int32 nDimension, Int32* pnTabDimension, STOperationDotNet* pstOperation)
this time it looks like it's loading the same dll but from different location causing conflicts. Now that's all. Its hard for me to explain this dll-hell but basically i would like to replicate whats happening when the application works well in the visual studio development server. I've also read that IIS does not resolve Added PATH without rebooting so i tried to add c:external manually to the PATH and reboot but same errors appears.
In my present project i have to convert some file formats into PDF.The source file formats may be MSOffice(.doc,.docx,.xls,.xlsx,.ppt,.pptx) and Images(.jpg,.png,.jpeg,.tiff).We wish not to use any third party library.The code should be in c#.
I need to popup my webpage from within our customer's websites. My webpage gathers some data in input boxes and then closes --- ie. It's just a basic form and all I need is to display it and give a close button to the user.
What's the best JS tool to do this? I found colorbox and it looks cool, but I am concerned that it will break my customer's site as it requires jQuery (and my customer may be using an older version than colorbox pulls in).
How do we code "findcontrol" with a third party control? I tried "TextBox" for Namespace="FreeTextBoxControls" Assembly="FreeTextBox" and it threw an error:
Object reference not set to an instance of an object.
Here is the offending line:
Dim Body As String = Convert.ToString(CType(lsvBlocks.InsertItem.FindControl("FreeTextBox"), TextBox).Text)
I want to create a digital signature, for my product, for creating the digital sigmature i want digital certificate. I came to know there are lot of third party available for creating digital signature. If any one know can tell some of third party for this.
