    - Understanding Web Services I'm looking into implementing Web services to provide product activation codes to resellers. This seems to be going fine. One large reseller tells me they support CGI for this purpose, as thought it's the same as Web services. Clearly, CGI is not the same as a Web service, but reading about it, it seems similar in that it somehow calls code running on my server. Can anyone clarify for me the primary differences between CGI and Web services? Specifically, can a CGI interface be implemented using ASP.NET, or could a Web service be made to work by code that calls CGI? Thanks! Jonathan Tag: Ajax Tag: 522195

    - Generating Letters Hi, I am looking for tutorials related to generating letters. If possible I would like these letters to be generated in Microsoft Word format, as that way they can be directly imported into my companies records management system. I have looked at various methods, Crystal Reports seems a little over kill for what I need, as I am only importing very basic data to the letter (name, address, title date ect), I had a breif look at word interop, and that worked well, but I read somewhere that it shouldnt be used with asp.net - why is this? So I am just wondering if anyone knows of any good tutorials to help me generate letters. Ideally, I would like to run it via a webservice, so that it can be consumed in more than one application, simply passing a ClientID of the recipient is all I envisage to call the service. Any suggestions of tutorials / further reading would be great. Kind Regards Tag: Ajax Tag: 522180

    - Missing Web log Entry's for file downloads Hi, I have been using the code (some of it has been removed for simplicity) below to allow authenticated (using ASP.NET membership database) users to get a file from their archive area. It seems to work fine, however I noticed that no web log entry is added when a successful download occurs (normally a 200 HTTP status code, however, if there is an authorization failure, it gets logged). I have a logging routine that logs a successful download to a database, but the W3SVC IIS log has nothing. The code below is contained in an .ashx file.

    - Upload a file to a different site Hi all I have 2 Web sites (Applications). For the purposes of this question let's say they are to be on 2 different boxes in 2 completely different domains. My users are going to be moving around from page to page in Site1 and then they are going to need to upload a file. This file upload should be to Site2. I would prefer a solution in which... ... the user clicks a link/button labelled upload ... a panel opens up (embedded on the first page) ... the panel is in reality a frame pointing at a page on the second site ... this new page offers the upload control. ... the frame/panel shuts down after upload is complete. I am open to launching a new page/tab instead if needs be. There are 3 requirements 1.> The users should not have to navigate back to the first site after the upload. - The 2nd site should ideally vanish. Perhaps we can get them to close a tab or a Div. Not sure really 2.> The upload should only take up bandwidth between Site2 and the browser. - One previous solution *seemed to be* to access the webservice of Site2 from the server side of site1 which of course meant that Site1 was also taking a hit on bandwidth. 3.> When the user initially clicks the link to open the upload panel, the web page must Site1's serverside (I guess some sort of Ajax) in order to trip it into creating a token which must be used as a part of the URL to site2. I am not sure however, how to achieve this. Does it even make any sense? I'm kinda stuck of where to start here. Any help greatly appreciated. -- Ror Tag: Ajax Tag: 522160

    - Question about loading usercontrols (I've been away from web app programming for a while. Most of my experience has been in 1.1. Now I'm using vb/Dot Net 2.0) Please explain a couple of things. First, I have a simple-minded usercontrol defined. No real code so far. Just a bunch of text boxes on a panel. I want to dynamically load one or more instances of the usercontrol onto the screen. Why is it that the command 'Me.Form.Controls.Add' will work with stock controls (like a textbox) but apparently not with usercontrols? (After a little bit of trial and error I found I could create usercontrols with the 'LoadControl' command. I think this is the first time I've heard of 'LoadControl'.) 2nd, in a basic web page, a control can be dynamically added with a call to the default 'form1.controls.add'. My current test page has a master page and I've found that 'form1' is not available. However 'Me.Form.Controls.Add()' seems to work the same. Are there any 'gotchas' here that I should be aware of?

    - database / document search control Hi I'm lookin for a bit of advice regarding search controls. We currently have a number of tables in an SQL server database which our app can search. The code uses LIKE querying. We'd like to update that to a faster, more robust system of searching (perhaps using full test indexing). But we'd also like to add the ability to search documents stored on our shared drive at the same time. The obvious solution is to update our current search routines to search the sql full text index, and then add in code to query either Search Server or the Indexing Service. However, that's a lot of coding and testing time. Is there an asp.net search component that will give us this search functionality to query both the database and the indexing service? Or are we on the right track rolling our own? Thanks Dan Tag: Ajax Tag: 522150

    - Parsing content from textboxes efficiently Hi there I=92m trying to come up with a smart way of parsing content from textboxes in C#. I have about 7-10 boxes with different content; dates, times, numbers and text that has to be parsed and inserted into my database. Of course the obvious solution is to make a lot of if=92s and parse each box one at the time with the properties I know and catch all exceptions on the way, if any, but does anyone has an idea of a smarter way of doing this? Thought about making a list of the boxes with content, so I don=92t have to waste time parsing the empty ones and catching exceptions.

    - DataRow EndEdit and AcceptChanges I found this in MSDN: "The BeginEdit method is called implicitly when the user changes the value of a data-bound control; the EndEdit method is called implicitly when you invoke the AcceptChanges method for the DataTable object." But what about the other way around? If I call EndEdit is AcceptChanges invoked? Since trying some test code, it seems to be that way. I am still trying to understand what the connection is between RowState, BeginEdit and EndEdit, and DataRowVersion. Does calling EndEdit have influence on RowState, directly or indirectly?

    - Relative URLs I need some help (and my apologies if this is not the right group) understanding how to properly form Relative URL's. I'm developing a site (Web Site, not a Web Application if that makes a difference) in VS 2005. The application is called OBS, and it's located C:\Inetpub\wwwroot\OBS. In IIS, it shows a Virtual Directory at that location, running an application "OBS", and with a Starting point "<Default Web Site>\OBS". When I specify relative URLs in links and Response.Redirect calls, I've been specifying it as "~/PageName.aspx", or whatever. Most of the time that works, but sometimes I will get a 404 Resource not found error saying that it could not locate the resource "/OBS/~/ PageName.aspx" I was under the impression that the "~" stood for the root, i.e., OBS. So why is it constructing the resource name that way? Also, I thought that "/PageName.aspx" should be equivalent to "~/ PageName.aspx", but it clearly is not, since that fails almost all the time. In one case (which seems to have stopped working that way now, for some unknown reason), the Redirect worked correctly when it was run from the Default page, but when it was run from a different page (still at the top level), it failed in the above manner. I seem to be able to get it work if I put the link in as "PageName.aspx", but I know that will break if I end up moving pages around to different directories, so I want to avoid that . Can anyone tell me anything that will shed some light on my obvious confusion? Thanks in advance for any help. Tag: Ajax Tag: 522114

    - Redundant Items in DD When binding a control to a datasource (SQL) using the configure data source or editing the SQL Query both VS2005 and 2008 have always shown duplicate (double) values in the controls list on all of my machines.

    - View asp.net site on a computer ? I have a roadrunner personal page internet site. I just found out it does not support ASP.NET. I've developed an asp.net site that I would like to show someone. I can't image this is possible but I have to ask to be sure. Is there any way I can send him something (maybe on a cd) that he can view on his XP computer. He does not have VSxxxx I'm sure. Who is a good isp that supports asp.net? Does ms publish list? thanks Tag: Ajax Tag: 522090

    - changing asp:button text on rollover using ASP.NET/VB.NET 2.0 I can change the text color of an ASP Button object on mouse rollover/rollout by doing this (in page_load) btnMyButton.Attributes.Add("onmouseover", "this.style.color='Yellow'") btnMyButton.Attributes.Add("onmouseout", "this.style.color='White'") But how can I change the text on rollover? I don't understand the javascript DOM enough to know what to do. I did try: btnMyButton.Attributes.Add("onmouseover", "this.text='My New Text'") And Tried btnMyButton.Attributes.Add("onmouseover", "this.style.text='My New Text'") Of course, none of these do anything. TIA, Jim Tag: Ajax Tag: 522085

    - Cannot initialize the data source for linked server Hi, I have this error when I run a stored procedure calling a linked server : System.Data.SqlClient.SqlException: Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "linkedServerABC" The problem is that when I run the exact stored proc in SQL Server in the query editor it works well. So why ASP.Net on the same server can't execute this stored proc? Any idea? Thanks Stephane Tag: Ajax Tag: 522051
