I have a really simple question. I have a web form with a couple text boxes and check boxes. I want to get data from my DB and set the values to the controls. Right now this is how my code looks:
--------------------------------------------------------------------------------------- Dim cmdSelect As Data.SqlClient.SqlCommand
'I must take the connection string and put it back in the web.config file. For now i am having problems getting it from thereCnDB = New Data.SqlClient.SqlConnection("Data Source=ORION;Initial Catalog=eisTEST;Persist Security Info=false;User ID=User;Password=password")
Try
CnDB.Open()Catch ex As Exception
Response.Write("Cannot open the database connection ")
Exit Sub
End TrycmdSelect = New Data.SqlClient.SqlCommand(strSQL, CnDB)
I am a classic ASP guy so I am used to recordset and old text1.text = RS("value") approach. I have done some work in ASP.Net 1.0 and my code in there used datareaders. Can someone give me some guidance here.
I'm trying to take the output of the Render method and bind it to the ReportViewer control. First of all, is this possible? If so, what is the best way to render the report (format: XML,CSV, NULL, etc), and then how to I 'bind' the result to the control?
I'm proving some code to demonstrate how I'm rendering the report: ... string format = "XML"; string devInfo = @"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>"; ReportExecutionService rs = new ReportExecutionService(); ExecutionInfo execInfo = new ExecutionInfo(); ExecutionHeader execHeader = new ExecutionHeader(); byte[] result= null;
rs.ExecutionHeaderValue = execHeader; execInfo = rs.LoadReport(path, null); string SessionId = rs.ExecutionHeaderValue.ExecutionID; result = rs.Render(format, devInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
Thanks, any help would be greatly appreciated. Peter
Ive run into a situation where some code im using will not function the same when between these two cases. So, this has me wondering what is going on behind the scenes. What is the sequence of events that are occurring that would possibly be messing things up.Here is the sample codeIts a gridview that is using a sqldatasource control. The code works fine, but if you want to bind the grid to a dataset and call databind yourself, things dont work as expected and the other features that the code performs just isnt happening, at least not for me.
I have search for answers to the all over google and every thing I have found so far did not work for some reason or anothr. . Here is what I am looking for I am codeing in Visual Studio using C#. I have been able to crate a connection and create taxt boxes with a submit button that when it is presed enters data in to a database (Sql server) what I have been unable to do is: 1. Display data in a text box. 2. Update data 3. create buttons to navagate through fields. I know I can do this with the gridview or datagrid but in really need a custome form for what I am doing.
I want to bind some data to a text box from sql server db. but when i run the page i get an error. here is my code. <form id="form1" runat="server"> <div> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:imacsConn %>" SelectCommand="SELECT Reportnumber FROM [SummaryBlue] WHERE REPORTNUMBER = @REPORTNUMBER"> <SelectParameters> <asp:QueryStringParameter Name="REPORTNUMBER" QueryStringField="REPORTNo" Type="String" />
Error: Exception Details: System.FormatException: Input string was not in a correct format.Source Error:
Line 25: </SelectParameters> Line 26: </asp:SqlDataSource> Line 27: <asp:TextBox ID="TextBox1" runat="server" Columns="<%$ ConnectionStrings:imacsConn %>"></asp:TextBox></div> Line 28: </form>

I get the following error when I try to substitute the strings in the databasedetails collection with variables: Error: Object reference not set to an instance of an object. StackTrace: at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.CheckLocalandDestinationStatus(Database srcDatabase, DatabaseInfo dbDetail) at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.TransferDatabasesUsingSpAttachDetach()
I created the following variables: strDestinationDB = AirCL2Exp_new3 strDestinationDBPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDATAAirCL2Exp_new3_Data.mdf strDestinationLGPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDATAAirCL2Exp_new3_Data.ldf strSourceDB = AirCL2Exp strSourceDBPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDataDataNewAirCL2Exp_Data.mdf strSourceLGPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDataDataNewAirCL2Exp_Log.ldf
I then assigned those variable to DatabaseDetails Collection:

The dataset2 control doesn't seem to want to place the text in the right spot. I put it right after the 1st Dataset and the user comments wound up all the way down in the footer of the site. I want them to appear in the white area just underneath the article text. Here's a link to one of my articles so you can see this. http://www.link-exchangers.com/view_full_article.aspx?aid=50 Down at the bottom left corner you'll see white space below the article. I'd like to have all the comments lined up going down the page. Is the dataset the best control for this task?
I am working on an SSIS project where I create two flat files for submission to a data contractor. This contractor requires a control record be the first line in the file. I create the control record based on the table information being exported.
What I would like to know is, is it possible to utilize the Header Section of the Flat File Destination Editor to insert the control record? And, as it is dynamic, what kind of coding must I do in order to utlise this functionality?
Guys - I have a textbox that I will store information from a variable. The textbox will store a form of report based on some calculated figure. I want the following items to be displayed:
Contact made on June 10 : 15 Contact made on June 11 : 1 Contact made on June 12 : 23
The problem is that I cannot get each item to start in a new line. I use chr(10) between them but it does not work. I have no idea how many lines of items will be displayed, as this information is stored in a loop. I keep getting this result:
Contact made on June 10 : 15 Contact made on June 11 : 1Contact made on June 12 : 23
How can I get each item to start in a new line in the textbox? this is a sample of the code that I use: strCnt = "Contacts made on " + Str(dtee) + " : " + Str(dtee_amt) strRep = strRep + Chr(10) + strCnt
I've got an nvarchar(max) column that I need to transform with some simple text processing: insert some markup at the very beginning, and insert some markup just before a particular regular expression is matched (or at the end, if no match is found).
Since the SSIS expression language doesn't support anything like this, is a Script Component the only way to go? Does Visual Basic .NET provide regular expression matching?
Can someone demonstrate a SIMPLE way to do this that does not requireadditional functions or stored procedures to be created? Lets say Iwant to execute the following simple query - "select * from clients" -and save the results to a text file, we will assume c: esults.txtHow can I do this in one step?
Hi All, I am placing a Matrix inside the table control for grouping requirements,but when we export the report to the Excel, the contents inside the table cell are ignored. Is there any way to get the full report exported, as per the Requirement.Please help me with this issue.
UPDATE #2: When it said "Do you want to install Microsoft SQL Server" I said "yes" and that caused it to work. I exited and re-ran and now the print runs w/o the "install SQL Server" (If the prompt had said "Do you want to install the print dialog" we wouldn't be having this discussion...)
UPDATE: After posting this i discovered that the same thing occurs when attempting to print the report direct from IE6: First a dialog pops up "Do you want to install this software?" Name: Microsoft SQL Server. When I click "Don't Install" I get the dialog "unable to load client print control." Since this happens direct from IE6 I suspect it's browser settings. I'll resume tomorrow and post a followup.
My WinForm C# app integrates Reporting Services by calling them from WebBrowser controls. The problem is attempts to print cause a dialog: "unable to load client print control."
I've read prior posts that say "enable Active-X in your browser" - I don't know how to do that from a WebBrowser control.
Any ideas how to support Reporting Services "Print" from within a WebBrowser control?

Hey guys, Am in need of help please, basically the program im working with at the moment is when you add a New Contract, it will grab the Contract Number you have entered, Post it over to another page, then using that number bind a Gridview. The SQL being "SELECT Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent FROM ECS_Contracts_Test WHERE Contract_Number = " & conNoVar (this being the Contract Number of the recently added Contract), however then it comes to Bind the Grid it kicks up an System.Data.SqlClient.SqlException: Syntax error converting the nvarchar value '2009P7899' to a column of data type int.But the Column Contract_Number is set to Varchar and all I really want to do is to create this gridview using this criteria and not convert anything! The Contract_ID is an int, which is needed as I increment it. Heres the error code: Public Sub BindtheGrid()'Bind the Contract Grid, where ContractID is used Dim SQL As String = "Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent" Dim objConn As SqlConnection = New SqlConnection(ConnectionString) Dim cmdstock As SqlCommand = New SqlCommand("SELECT " & SQL & " FROM ECS_Contracts_Test WHERE Contract_Number = " & contractQueryID, objConn) cmdstock.CommandType = CommandType.Text objConn.Open() GridView1.DataSource = cmdstock.ExecuteReader() GridView1.DataBind() objConn.Close() End Sub If you need any more information then please let me know. Mucho Aprreciated

I have this stored procedure that almost works: set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go

If I hard-code that to a 2, this works. With the fieldname there, SQL Server Management Studio says: Msg 4104, Level 16, State 1, Procedure udForumTopicMessageByForumTopicID, Line 9 The multi-part identifier "ftm_parent.ForumTopicMessageID" could not be bound. If any experts out there can help me out with this, I'm sure it wouldn't take much to fix.

I am new to .net and I am using Visual Web Developer 2005 Express with SQL Server 2005 Express. What I would like to do is connect to my SQL database (which resides in the app_data folder) and open a table and pull out a field and place it in either a textbox or label on the page. No editing or deleting. Just simple one field binding. By the way, I can do this with all the cool built-in tools of VWD, but I want to know how to do it all by hand. I would really appreciate it if someone could help me out.
I am using C#.Net, Visual web Developer, SQL server 2000. I have a SQL query which I am binding it to a DataGrid.

I am able to bind one column to this databound column using following code. BoundColumn ETDDate = new BoundColumn(); ETDDate.HeaderText = "ETD Date"; ETDDate.DataField = "OSP_FSD"; mygrid2.Columns.AddAt(ETDDate); but now I want to bind this databound column based on the following criteria to two different database columns. if(ord_split = 1) { ETDDate.DataField = "OSP_FSD"; } else { ETDDate.DataField = "ETD_Date"; } How to get value of ord_split before binding SQL to teh DataGrid? i.e I just want to take value of ord_split and not all the values of SQL. Please Help!
