The essential process is that, files converted to byte arrays are passed along with the full name of the file not the path including the extension as arguments to the UploadFile web method. The byte array is passed to a memory stream, and a file stream is opened pointing to a newly created file named the name of the original file within the target folder used to store the files. Once the file stream has been created, the memory stream is written into the file stream and then the memory stream and file stream are disposed of.
The web method is setup to return a string; if all goes well, the string returned will read, "OK", if not, the error message encountered will be returned to the caller. The test application contains a single Windows Form class; this form contains a text box used to display the name of the file selected for upload, a browse button used to launch an open file dialog box which is used to navigate to and select a file for upload, and an upload button which is used to pass the file to web service so that the selected file may be stored on the server.
The next bit of code in the class is private method used to prepare the file for submittal to the web service and to actually make that submittal. The code below is annotated to describe the activity but the essential parts of the operation are to check the file size to see if the web service will accept the file by default, the web server will accept uploads smaller than 4 MB in size, the web config file must be updated in order to support larger uploads , and to convert the file to a byte array.
When everything is ready, the byte array and the name of the file including the extension is passed to an instance of the web service web method. Note that, when setting up the demo, you will have remove and add the web reference back into the project in order for it to work for you. This custom type consists of an element whi I have a web link which contains nothing when you visit that web link.
But when you view the source it will show the xml source in it. I want to create that xml file through web service and make these xml files availible for my application. Best RegardsShaukat Waqar Web service in.
Here is the wsdl. What are the differences between these two? I am trying to create a Session that will keep update the value whenever it navigate to any page In what kind of situation we use XML or vice versa? All developers, even novices and hobbyists, must be a What's the best approach to learn and use it? Please mark the post s that have helped you as "Answer" 1. They are different things 2. Tomas Restrepo I would like soemthing neutral if possible. I am thinking of approaching this subject for my dissertation?
I noticed some good books at barnes and noble that discussed the subject. The web page that allows the end user to perform the CRUD operations look like this:.
To begin developing this example, create a new ASP. Then add Models, Views and Controllers as usual. This wizard is run when you add a new Entity Data Model into the Models folder. Make sure to pick Code First from database open while running the wizard. At the end of this process you get two classes - Northwind. These classes are shown below:.
We do this just for the sake of simplicity. Name the Controller as EmployeeManagerController. This controller will have five actions to perform the CRUD operations. These actions are shown below:. Then add HomeController to the Controller and also the Index view. Add Scripts folder under the project root and place jQuery library in it you can also use a CDN if you so wish.
Open Index. Shown below is the calling of the SelectAll action. The dataType is set to xml. The success function receives XML data from the server. A sample data received in this method is shown below :. The jQuery find method is then used to iterate through all the Employee nodes.
For every Employee found, its EmployeeID is extracted using find and text methods. The EmployeeID is then added to the dropdown list. User posted Hi there, Thanks for the reply. User posted I want to do in ASP. User posted Hi, Thanks mate. It worked well. Sorry didn't even do this simple step. Apologies i'm new to XML..
