  If I have a property, method, or event, which has a particular attribute, of a base class, is there any way of changing that attribute in a derived class without creating a re-implementing the property, method, or event. By re-implementing I mean creating a new property, method, or event of the exact same name and signature.

• Steve St.Jean How to deploy web services created using Visual studio 2005 in IIS server

  Hi, I have created web service using Visual studio 2005 and am trying to deploy it in IIS server. But my web service is created in local server only. How I can deploy it in IIS server how exactly do you mean deploy You should be able to just create a virtual directory in IIS and place all the files in there (.asmx/cs/bin folder) and hopefully that should be ok.   The other thing you could do is create a setup project, and use this project to create an installer to deploy your web service, this would be better and more professional ...Show All

• TheInsaneCoder The schema returned by the new query differs from the base query.

  Well I'm trying to make a query but everytime I hit the 'ok' button when I'm done in the Query Builder it says the message that is in my title. What am I doing wrong :( Thanks in advance little bump :x I checked our internal bug database and this appears to be by design, you cannot add or remove columns from the query builder. Seems a bit odd, but there you have it. "Add a database connection to server poutine, database Northwind, ..." And how do I do this "Hence query builder is not very useful!" Is there another way to make query or querylike things then Hi all, I have this msg to ...Show All

• crash33 how to associate a filetype with a windows service

  suppose i have a custom file format with an extension. how do i associate that file extension with a windows service. suppose when i click on the file with particular extension '.dmz', the particular windows service is automatically invoked. should i use filesystem watcher component. Hi, Sure. Since you have your own filetype, you can associate the type with another program that you would need to write. This is a simple proxy that would then communicate with the Windows Service. You would not use the File System Watcher component - that's for monitoring when files get created/modified for eg. Cheers i do not want to exactly associate a file type to associated with a service. but i want the service to respond when i clic ...Show All

• ejstembler Web Services - can only be used by other ASP.NET apps?

  Can web services made with VS 2005 and published to an IIS web server (with .NET 2.0) be used by web servers not running ASP code Rob. 1st one is what I mean -- can you be more specific about "generally speaking yes". Example of how a web code from non-ASP web server would make a call to my web service And how the caller would read the results returned from my ASP.NET web service. The ASP.NET web server is SSL -- is SSL a road block for web services Rob. Thank you. Going thru the article Step 5.

• jturpin Going through every element on a page

  Hi, I have elements dynamically created on a Web page (using ASP.NET). Some of them have a special attribute set. On the page load, I'd like to scan through all the elements on my page and if the attribute exists and is set, do some action on that element. All this in JavaScript. There must be a way to do this recursively right Any help would be appreciated. Thanks, Skip. I think that the .NET "Controls" array is just what you are looking for. In ASP .NET the "Page" object contains a property called "Controls". It is an array that contains all of the controls on the Page. You can find all of the controls on the page by writing a program that loops through the ...Show All

• Cory Cundy Updates Using the Entreprise Library DAAB

  I am using the Jan 2006 Enterprise Library DAAB. One of the big benefits for me is abstracting myself from the database. I work for an ISV and our product must run on multiple databases. With that said I have been instructed to stay away from stored procedures. The dataadapter can create Update, Insert and Delete commands dynamically based on the Insert Command. I am trying to figure out how to dynamically create delete, insert and update statements using the DAAB. It appears that you to update using DAAB you must create your own commands. Therefore I decided to try and create a generic routine that would create these commands based on the columns in the dataset. I can cycle through the columns in the table to get the column names and ...Show All

  Im recieving some data from a web service call that is in a format of elements with many attributes. Id like to pull this data into a DataTable, with one of the fields set to be a DateTime type. At present, im handling like so: - recieve xml response as string - parse xml into new format as elements with values (versus attributes) - use Dataset.LoadXml to load this xml stream into a datatable - (hack) create a datatable programatically and assign datetime type to one column - copy table from dataset into a DataRow [ ] array - then populate the new table from data in the DataRow [ ] - apply a sort expression to the default view of the new datatable - bind my dataview to my gridview control The above steps are needed because if the xml ...Show All
