WCF / ASMX :: Want To Delete The File Using The Same Web Service Where Stored That File In The Another Database?
Aug 9, 2010
I m accessing another application by consuming webservice of that application. I m sending file to store and retrieving file from other dabatase. Web service is the only to access another application.Now, I want to delete the file using the same web service where I stored that file in the another database.I m getting exception and I m unable to figure it out.
I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Public Class CustomValidate Inherits System.Web.Services.WebService 'ACCESS VIA JSON <System.Web.Services.WebMethod()> _ Public Shared Function AJAX_Test(ByVal date1) As Boolean... Return True End Function End Class Javascript: JQuery JSON function isDates(source, arguments) { var isValidDate; $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "CustomValidate.asmx/AJAX_Test", data: '{date1: "' + arguments.Value + '"}', dataType: "json", async: false, success: function(result) { isValidDate = result; }, error: function(httpRequest, textStatus, errorThrown) { alert("status=" + textStatus + ",error=" + errorThrown); } }); arguments.IsValid = isValidDate; }
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
I have a wsdl file which are the definition of several methods of the web service associated . I want to create this web service in order to consume it through a Java web service client.How i could do this?
I wrote a small web service (asmx) to write stuff to a file on the server. It works fine when run in the VS2008 test container. But when I run it under IIS on a remote machine, I get:
System.IO.DirectoryNotFoundException: Could not find a part of the path 'y:grahammiscprops.txt'.
'y' is a mounted drive on both the test and remote machines. The path really does exist. It works on the test machine; not remotely. So:
Is it the fact that 'y' is a mounted drive causing it to fail remotely? or Is it the fact the the path lies outside of the web application directory structure? Is there something I should put in web.config??; or
Is something else the problem? I would have thought that the service running on the server could do anything it wanted! It's not denying me access to the file; it's saying it can't find it??!!
I have a large web application that uses File.Exists() in a global file utility class flawlessy for several years now. I just built a new ASMX web service that calls that same method in our file utility class, and it returns False for the same exact file paths that are being passed in the web application. The paths are absolute system file paths, and they match on both the web service and the web app.I am confused... Why might this happen? The method I am talking about is only a few lines of code. A couple of lines simply validate the file id parameter being sent into the method. The last remaining line is this:
[Code]....
The previous line of code calls another method that uses a String.Format to insert the file id into the file path. That's it.
I've been trying to get my Web Service in my wcf project to be able to reference the resource objects in my resource file but to no avali.Please kindly advice and assist on what went wrong.
I am adding a reference of class library in web service in VS2008 and it is not copying the .config file from class library to web service. I have checked the property "Copy to output directory" of .config file and its value is "Copy Always".
I've been reading quite a few tutorials on web services and xml files and one thing isn't quite clear to me. If I want to create an XML file on the fly the tutorials are pretty straight forward but, I want to grab an existing XML file from the web server and return the whole thing. Do I need to read the XML file and send each individual node or is there a way to send the file all at once? The tutorials imply that the whole file could be a node but I'm not clear on what that entails or if it would work. Also do you have a link to an example?
I have a WSDL, and I need to write this web service. (I am not the client, I am the provider of this service) Is there any tool and/or best approch to create this Web Service?
but when I tried to add the service reference to the silverlight app, the Add Service Reference window would show me that there was a service file, but the node wouldn't expand to show the rest of the files that contain the services and what not. I got this error instead:
"An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately."
"Parser Error Message:There is no service behavior named 'AdventureWorks_WebServer.Service1Behavior'."
"Metadata contains a reference that cannot be resolved: 'http://localhost:55579/Service1.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again."
I want to delete file available on server and same time I want to update the filename column in my database.If I delete file first and then update database and an error come in updating database my file is already gone.If I update database first and then delete file from from disk and an error occur my file information in database is already gone Can any one tell me how I can do it both successfully. I means either both operations should succeed or I should not lose my physical file or its information in database.
When I am creating a new form, I am inserting "RequestId" of particular form in Textbox as well as uploading multiple file (that comes in Gridview)and on save button click, those gridview multiple files with "RequestId" are saved in Database as below:
Now, I want that If I delete any file from the Gridview(which has all uploaded files), I want that file to be deleted from database table also.Currently on Deleting file from Gridview, files from "Folder" are deleted not from Database.
I have a text file stored in my sql DB. in that .txt file I have certain numbers like:
99435 87889 33455 33555 34556
How to get the count of these numbers from the txtfile stored in the database? Also to read the file and fetch the number one by one in a string? I am using asp.net (C#)
