Connecting To SQL Db In An Asp.net Page
Nov 20, 2003
Ok, I'm an experienced asp developer switching to asp.net.
I've used the "Quickstart Tutorials" (http://www.asp.net/Tools/redir.aspx?path=quickstart) and have gotten started that way and built a few things based on that, but they only show XML connection info. Now I need to switch to SQL so I can connect to MS SQL Server for some stored procedures.
Anyone have suggestions?
(I've dug through some articles on msdn, etc, but I've only found so far theory and not code. And let me tell 'ya, I'm big on learning about code from code.)
If this helps, the specific tasks I'm trying to do are:
Have user select a static value from a drop down list, enter a word in a text box, and submit the form (so far so good), which connects to the db and returns the datagrid filled with results (the part I don't have). I already have my sp, just can't connect to it and get results back into the page.

Hello, I'm using Visual Studio 2003 and I need to be able to connect to an SQL Server 2005 Express database on the same machine using ASP.NET pages, but I'm having difficulty getting the pages to make a connection. I'm new to ASP.NET and I'm probably making some totally elemental mistake. I'd appreciate any assistance anyone can offer. I have pasted in part of the codebehind file for a web form (asterisking out the database name) and the error report that appears in the browser when I call the page.using System;using System.Collections;using System.ComponentModel;using System.Data;using System.Data.SqlClient;using System.Drawing;using System.Web;using System.Web.SessionState;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.HtmlControls;namespace WebApplication2{ /// <summary> /// Summary description for WebForm1. /// </summary> public class WebForm1 : System.Web.UI.Page { private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here string strConnection="Integrated Security=SSPI;Persist Security Info=False;"; strConnection +="initial catalog = ******;server=WILL-000993DB49\SQLEXPRESS;"; SqlConnection objConnection = new SqlConnection(strConnection); objConnection.Open(); objConnection.Close(); } #region Web Form Designer generated code override protected void OnInit(EventArgs e) { // // CODEGEN: This call is required by the ASP.NET Web Form Designer. // InitializeComponent(); base.OnInit(e); } /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.Load += new System.EventHandler(this.Page_Load); } #endregion }} Server Error in '/WebApplication2' Application.

I'm using the IBM DB2 UDB for iSeries IBMDA400 OLE DB Provider to connect to an AS/400 db2 database
I'm trying to do a simple pull through of table data.
My connection string is :
Code Snippet
Provider=IBMDA400.DataSource.1;Data Source=WAS400;Persist Security Info=True;Password=**********;User ID=svcorbit;Initial Catalog=S652F01E;Force Translate=0;Catalog Library List=OSLD1F3, PAOS21, OSLPLF3
I'm getting a code page conflict when I try to import the data into SQL Server. This happens when I edit the OLE DB Source component:
Code Snippet
The component reported the following warnings:
Warning at {47FF55CB-AA24-45A4-B0DC-2807EC6D3EC1} [OLE DB Source [3570]]: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.
and at package validation level when trying to run:
Code SnippetError at Data Flow Task [OLE DB Destination [970]]: Column "ACRC10" cannot convert between unicode and non-unicode string data types.
I've tried using the default code page on the component, that doesn't work. I've tried changing the code page to 285 (which is what it is on the AS/400), that doesn't work.
I'm running out of ideas... help!

Hello I have a project that uses a large number of MS Data access pages created in Access 2003 and runs on MS SQL2005.
When I am on lets say my client, (first page in a series) data access page and I have completed the fields in the (DAP), I am directing my users to the next step of the registration process by means of a hyperlink to another Data access page in the same web but in a linked or sometimes different table.
I need to pass data entered /created on the first page to the next page and populate the next page with some data from the first page / table. (like staying on the client name and ID when i go to the next page)
I also need the first data access page to open and display a blank or new record. Not an existing record. I will also be looking to creata a drop down box as a record selector.
Any pointers in the right direction would be appreciated.
I am some what new to data access pages so a walk through would be nice but anything you got is welcome. Thanks Peter€¦

The following objects are placed on the Report body of the Report pane of SQL Server 2005 Reporting Services :
<textbox: expression1>
<textbox: expression2>
<table:table1 with at least 30 columns and 30 expressions>
<textbox: string1> - considered as the Title in the Footer section of the report
<texbox:string2> <textbox:expression3>
<textbox:string3> <textbox:expression4>
<textbox:string4> <textbox:expression5>
<textbox:expression6>
I can't find any explanation why is it string1 and string 2 of the footer section of my report displayed separately from the expression3 which is aligned on it and the rest of the object on the second page.
The expected design is that all Footer items should be displayed together of whether it is placed on the first page or on the last page.
As a workaround of this, I converted string 1 into an expression (Added = and enclosed the string with double quote).. As a result, all of the items in the Footer section are now placed together on the last page of the report.
I also remember one of the issue I encountered before where the Footer items where placed together on the first page and still have space at the bottom of the page, but then expression 6 is forced to display (alone) on the last page of my report.
I can't find any discussion related to this, I wish somebody could give me an idea why RS behaved like this.
Thanks in advance

Hello,
If I have a report that includes a page header, the report viewer will render the report at the full width, but if I hide the page header and show only the body it will use the absolute width of the report.
I have a 7" wide report, with .75" borders set on each side.
Interactive & Print size are set to 8.5x11
Changing these sizes has no effect on the behavior of the viewer, which appears to ignore them.
When I view this report in the local viewer the contents fill the window if there is no page header.
If I enable the page header then the report is drawn at 8.5" wide, leaving a _big_ white border on the right side.
Any comments or workarounds that anyone knows? I know the local viewer is not a standard configuration (at least it seems) but it is what we need to use.Thanks,//Andrew

How can I print a field that is in the dataset on each page? I added a textbox in the Page Header and use =Fields!ProjectName.value in the value property. I got an error "Fields cannot used in page header and footer."
How can I have the table header shows on each page? Currently if the data goes to the second page, there is no table header.
Thanks.

In SRSS 2005 (SP2) my page header seems to take up the same amount of space on the
1st page it would take if it were to print; I have PRINT ON FIRST PAGE set to
false - the header doesn't print - it just leaves the same amount of space.
How do you get the report to ignore that. I do have a report header built
into the body of my report. I have tested this by increasing the size of my
page header and it does move the report up or down on the 1st page by that
amount.

I'm hoping that someone can shed some light on this for me... I'm using SSRS SP2 and I have a basic report using a single list object which, at the moment, should print only two pages based on the results of the underlying query. When previewing the report, it shows the two pages. But when the report is printed or exported, there is a blank page before each report page.
What I've done so far:
1) Verified the properties of the list object and made sure that 'Insert a page break before this list' is not checked
2) Ensured that there are no hidden objects that could be causing this behavior
3) Ensured that the report size + margins are within the boudaries of an standard 8.5x11 paper size
Any suggestions on something that would solve this issue?

I am running a DBCC SHRINKFILE on "FILE1" of a database (it has fileid = 1)...intent is to remove 70GB of file space:
DBCC SHRINKFILE (N'FILE1' , 400000).
For the SPID that's doing the shrink, In activity monitor you can see:
Waittype: PAGEIOLATCH_EX on resource: 9:3:15411328
(the DB is dbid=9)
But why does it need a page from fileid=3? Are there page dependencies between files that prevent moving a page within a given file? Does it need that fileid3 page to come along?
Its just sitting there in the SUSPENDED state for the last hour....I am going to leave it another 5 hours or so before cancelling.
The dm_exec_requests has an estimated percent complete at 83% and holding....not sure if I can believe that.

Hi all
I have a problem which I am really struggling with. I have a report that normally spreads over three pages. We have a list setup so that for each customer it picks up fees and expenses and displays it in sections. We have a page break after FEES so that expenses start on a new page. FEES and expenses are tables.
We need to have a page footer set for the bottom of the report but to appear on the first page only per customer. I.e. we do not want it showing on the EXPENSE pages. We have played with the IIF command but can not seem to print htis per customer only by using global variables.
=IIf(Globals!PageNumber=1,"(Please note 30 day invoice period)
The example above however only prints on the first page of the entire report. So if three customers appear then this will only appear for the first customer and I have a feeling I may not be able to link this to list.
If I can not use a page break and enter this into the list then I have a problem with the text field moving up and down depending on the size of the FEE section. For example if 5 fees are brought back then the text field will be lower then a customer that has only 2 fees.
I after a solution that can either allow my page fotter to appear every time a new customer appears on a page and hiddern for the sub sheets. Or the ability to allow my text field to start at a fixed position on my report. Has anyone had a similar issue.
thank you
Michael

Is it possible to force the content of the page footer to always display at the bottom of a report? I have a report that shows customer orders. It has its interactive height set to 5 inches. There is one customer order per report page. Most of the reports don't require 5 vertical inches (but some do).
How can I make sure that the stuff in the page footer (date, page number, etc.) always gets rendered in the same position for each report? Currently, the page footer follows the last detail line so the footer information sometimes is only midway down the report page.
Thanks.

I think I know the answer but I have a report that is supposed to print in Ledger. It has a header that has report information on the left and on the right has page count and date run. When the user resizes the page to letter, only the first part of the header shows (left piece with report information). Instead of resizing the header it seems it truncates it. Is there a way to resize it. If I move the right side over it looks centered on the Ledger size.
