ADO.NET :: Can't Get Reader.hasrows And Reader.read To Work Together In Code Behind
Feb 22, 2011I have some code in my vb.net code behind that queries a database, and if there is data, outputs it from the codebehind to a datalist on my asp.net page. In addition to sending the data to the datalist on the page, I need to take the value from "mbillaty" that is returned from the sql query, and have that value be the selected value for a drop down box also on the page. I can get either the datalist to fill, or the selected value for the dropdown box to be selected depending upon which bit of code I place before the other (ARGH), but I can't get them to both work together on the page. What am I doing wrong?

View 1 RepliesC# - Integrate Many Sources Into One RSS Reader?
Mar 8, 2010I'm looking to integrate a bunch of RSS/ATOM sources into a feed for our intranet. This is outside my usual realm of work so I've had very limited exposure to this.
I'd like to integrate all the feeds into a single reader such that all the news items are in chronological release order.
Is this doable? Do I need a special component? Or can I make the ASP.NET integrated components do all this simply enough?

View 3 RepliesC# - Data Reader Trimming The Leading Zeros?
Jan 13, 2011I have a string coming from a stored procedure looks like '001234567'.
sqlCommand = new SqlCommand("csp_Bbp_OBN_GetBasePageList", BBConnection);
sqlCommand.CommandType = System.Data.CommandType.StoredProcedure;
sqlCommand.Connection.Open();
// Run the SQL statement, and then get the returned rows to the DataReader.
accReader = sqlCommand.ExecuteReader();............
In my case, from the stored procedure I am returning the varchar, after executing and reading it I am getting the value to basePage.GrouNum which is a string. So, I don't see where it is trimming the leading zeros.
Example: GroupNumber in the table is : "001234567"
BasePage.GroupNum after reading from DataReader : "1234567"
But, I do not want the leading zeros being trimmed.
Identify Whether A Browser/reader Is Being Used By Someone Who Is Visually Impaired?
May 20, 2010I have to provide a 508-compliant version of a page for the visually impaired and it isn't practical to just modify the page. Thus, I have created a new "reader-compatible" version of the page for the handicapped. The question is how I can tell if someone is using a reader rather than a standard browser? Is there a "header" or "useragent" value typically used by these non-standard browsers that I can look for?

ADO.NET :: When To Use 'reader' Versus A Datatable, Table Adaptor?
Sep 20, 2010I'm making the leap from using all the 'wizards' that are built into VS, and have been doing more with code-behinds. But, I'm curious as to when/why I should use a reader, versus a databable, table adaptor to "manage" the data returned from a stored procedure. Typically, the data is to be displayed on a webpage, and not written back to the database. What's the difference? When should I use one over another?
View 2 RepliesVS 2010 - Adobe Reader In Web Browser / IFrame
Jul 25, 2011Our ASP.NET application allows the users to review any number of PDF forms. A simple listbox holds filenames and the forms are displayed inside a standard iFrame. The setup is simple and effective: when the user clicks on a filename, that filename is loaded into the iFrame, and shown to the user.
Users are allowed to digitally sign the forms. For appearance purposes, a bitmap of the user' signature is generated and placed in the appropriate location of the PDF form.
The bitmap file format is GIF, and the background is transparent.
We use iTextSharp for form-filling, and we also use iTextSharp to place the bitmap on the forms. Nothing special.
We can readily verify that the signature bitmap is correctly placed on the form, and that the bitmap itself is definitely transparent.
Problem 1:
After placing the bitmap of the user' signature on the form, the form is reloaded and displayed to the user (for verification) and, in most cases, the forms do not display the bitmap. Opening the PDF reveal that the bitmap has been placed and is definitely visible in Adobe Reader (9 and 10 - these are the versions available for testing).
Experimentation and quite a bit of research seems to suggest that the problem lies in caching. One of the possible solution/suggestion is to append a time-stamp or a GUID to the URL, when loading the form after applying the bitmap. In theory, this should prevent Adobe Reader from using a cached copy of the PDF form.
We have tried appending a time-stamp and/or a GUID, without any success: the forms still display without the bitmap. At the risk of repeating myself: the PDF form is correctly signed, and the bitmap is correctly placed. It is just not visible.
This problem seems common to users running the application on intranet web servers (IIS 7). The one application instance running on public web server (IIS 7) does not seem affected by this problem.
Problem 2:
As mentioned, the GIF file generated by our application has a transparent background. In almost all cases, Adobe Reader (9 and 10) seems to understand and respect the transparency of the bitmap.
In one very peculiar case (when the application is running on a Windows 7 64 bit machine with IIS 7), when the bitmap is placed on the form, it becomes opaque (complete loss of transparency).
Again, the problem seems related to Adobe Reader, because the bitmap being applied positively sports a transparent background.

Adding Images In Loop (while Reader.read) Fails
Mar 27, 2011I have following code that I can only add one image per row although I can add Listbox items as I wanted.
If "imgtag" 1~5 is checked, I get these in the listbox.
ie. ImageID = "cat"
listbox1. item gets - cat1, cat2, cat3, cat4, cat5
however I can only create the last image instead of 5 images.
- imageID - cat5
I assign each image unique ID.
