VS 2012 / Saving File Generated By Response Object?
Apr 12, 2013
i have a data grid view that i roll over and generate a tab delimited file out of using the reponse object in ASP. to wit...
Code:
protected void CreateTabFile()
{
var d = DateTime.Today.ToShortDateString();
d = d.Replace("/", "");
var filename = "BankRecon";
filename += d;
Response.Clear();
Response.Buffer = true
[code]....
how do i set it up to save the file to the datastore folder i have on the site itself, i want to automate an email and send this as an attachment, the email part works, but if its not in a consistent place i cant attach it. its an asp.net webforms project not a website project.

By using the following code, i save the dateandtime to my MSSQL DB .
Code:
Dim dateTimeToConvert As New DateTime(Now.Year, Now.Month, Now.Day, Now.Hour, Now.Minute, Now.Second, Now.Minute, DateTimeKind.Utc)
Dim easternTime As DateTime = TimeZoneInfo.ConvertTime(dateTimeToConvert, easternZone)
Dim nowtime As DateTime = easternTime.ToUniversalTime
TIMESTAMPSqlDataSource1.InsertParameters("datee").DefaultValue = nowtime
TIMESTAMPSqlDataSource1.insert()
In the DB it saves the time as 21:.... but when I view the time using a gridview it shows 1:... (the correct time I want to show is the 1:... )
HTML Code:
<form id="form1" runat="server">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" />
[Code] ....
I'm not sure why i'm getting two different dates?

add the validation controls to them.The first page has a series of text boxes with autopostback = true. I can put CompareValidators onto the form and assign them to the textboxes, and they seem to work right. On my second page, however, the controls are being built on the server using vb code. The CompareValidators seem to work on the client side. On the server side, however, the CompareValidators always have an IsValid property = true, even when the value of the textbox clearly violates the conditions. I've checked all the properties I can think of and I can't see any difference between these dynamically generated validators and the static ones I have on the first page, so I'm thinking there must be something else going on.

I have a class TicketOrder. It's not recognizing my lstSectionNumber (Tickets.TicketForm.lastSectionNumber is inaccessible due to its protection level).
Here is the code for TicketOrder class:
public class TicketOrder
{
public TicketOrder(TicketForm form)
{
this.form = form;
}
//Declare static variables
[Code] .....
This is my code behind:
public partial class TicketForm : System.Web.UI.Page
{
//Declare variables
int myInt;
TicketUser user = new TicketUser();
TicketOrder order;

I use ASP.NET C# with AJAX Professional (http://www.ajaxpro.info)1) I have a div container with Panel control, Panel control should hold DropDownList that will be generated in codebehind function:
[Code]....
2) I have a JS script function "getDDL" that sends data to codebehind function and then it receives response with generated Panel and DropDownList controls:[Code]....
3) Codebehind function "GetDDL" must return generated DropDownList inside the Panel control:
[Code]....
So the problem is when I try to get the generated Panel and DropDownList through the JS response I receive only the text "System.Web.UI.Design.Panel" or something like that, tried to generate only DropDownList - similar text shows up "System.Web.UI.Design.DropDownList".But when I call a codebehind function to get these two controls I see them without any problems. Why I can't get them through JS? I do everything fine, debugged million times and didn't see any problems, I can't figure out what's wrong with JavaScript?

I have a default.aspx page, it contains a checkboxlist and button (Button1). There are other items too but not significant for this question.
The user selects an item in the checkbox list. Based on which item is selected, in my button click code, I take the user to another page (Page2, for example). In that page I have TextBoxes, where user fills some numeric values. On this page (Page2) I have another button (Button2). In the Button2 Click code, I want to use logic, where I need to know what was checked in my checkboxlist in previous page. How can I do that. I get the error
Error 17 The name 'CheckBoxList1' does not exist in the current context
On default page Button click I have like this..
[Code].....
1. How can I recall what was checked in default page checkboxlist?
2. Secondlay, the values user enters in this page (page2) in TextBoxs, I would need to use them in later pages, how can I use them in later pages. TextBoxs have unique IDs.

I have a web service that takes an XML string for input and saves the XML to a file. The filename is created from the date and time and a random number generator. The program also edits the XML as it processes, and there can be errors. When there's an error, I create an email which describes the error and then repeats the XML in the body of the email. I am using another web service written in-house to send the email.
I want to include in the email a link to the filename I saved. What is the best way to do this? I think I need to use HTML, but there's an html flag I pass to the email web service which needs to be false. When it was true, the XML wasn't formatting.

I am trying to open this file which exists and runs fine on my development machine. But when I deploy to my VPS with IIS8 I get this error:
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
I copied the same data.db file from my machine to the server which worked for me. Do I need to do anything in IIS8 to recognize this file and let me use it?
Code:
Using conn = New SQLiteConnection("Data Source=" & Server.MapPath("data.db"))

I have overridden the following methods:
LoadPageStateFromPersistenceMedium()
SavePageStateToPersistenceMedium(object viewState)
in a class that my page derives from, so that the viewstate can be stored in DB.
Now, on page_load of my page, I am checking what control caused a postback & based on that I am forcing execution of 2 button click events in a row (by overloading those click events & calling them explicitely), but the behaviour I want is as if the execution of those 2 button click events went through the regular page life cycle.
Here is the sequence of events that happen in typical page life cycle & notice I want to alter behaviour at step 4 (on load):
1) Initialization
2) LoadViewStateData (here the viewstate is loaded from my database using the overridden LoadPageStateFromPersistenceMedium)
3) LoadPostBackData
4) Load
Here, I would like to force execution of 2 button_click events based on whether a particular control posted back.
4.1) imgBtnPrev5_Click()
4.2) imgBtnPrev4_Click()
Now, when the imgBtnPrev5_Click() is executed, the viewstate is already loaded, so we are fine. But after execution of imgBtnPrev5_Click(), I would like to update the viewstate object in memory & then call the overridden SavePageStateToPersistenceMedium (by passing that updated viewstate object as its parameter) and then before execution of imgBtnPrev4_Click(), I would like to call the overridden LoadPageStateFromPersistenceMedium.
5) RaisePostBackEvent
6) SaveViewState
7) Render
My question is, how do I update the "viewstate" object of the page - that is passed to SavePageStateToPersistenceMedium with the changes made to the controls in imgBtnPrev5_Click()?

I need to save a file into special folder.
if (TextBox1.Text == s)
{ MessageBoxResult mbr = MessageBox.Show(this, "Do you want to save file?", "saved", MessageBoxButton.YesNoCancel); // if (mbr == MessageBoxResult.Yes) // { // //string path = string.Empty; // string path; // path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "abcFile"; // if (!Directory.Exists(path)) // Directory.CreateDirectory(path); // }
It creates a folder abc if it doen't exist, i need to save s where s is a textfile.

I am using ASP.Net MVC2 and LINQ to SQL. I am using DataAnnotations and model binding in conjunction with a Form/View and its working beautifully well. Loving that.. My view is an "Add new Employee" form that's adding a new "Employee" complex object. Every Employee also has a child complex object called an "Address".
I am using the bound Html helpers in the view, such as Html.TextBoxFor(model => model.NewEmployee.FirstName) for example. Working beautifully well, validating beautifully well both client and server and coming into the controller fully populated and ready to be saved! Exciting.. ModelState.IsValid returns true and I go to save the new Employee.
The Employee is created fine but the system also creates a blank/new Address record in my Addresses table even when the Address fields are blank! How can I prevent any Address from being created, in situations where I ONLY want to create a new Employee with no Address. An example is when the user supplies an existing Address, then I wish to simply set the new Employee's AddressID to that of an existing physical address (I hope that makes sense). But it could apply to any situation where you need to create a new complex object, but you don't wish for LINQ to create any of its child complex objects. I have tried setting NewEmployee.Address = null after it is received in the controller, but even after that, a blank/new Address is still created. Even if I try NewEmployee.Address = SomeExistingAddress, it does correctly link the Employee to the existing Address, but it STILL goes off and creates another redundant new/blank address record! Which is really weird..

I have a "Create New Employee" ASP.Net MVC form. My complex object is an Employee and an Employee has an Address, which is another Complex object. On my View/Form I collect all required values for both the Employee and the Address. I'm using the bound HTML helpers such as: Html.TextBoxFor(model => model.EmployeeAddress.StreetName)
AND
Html.TextBoxFor(model => model.NewEmployee.FirstName)
This is all working beautifully well. Model binding is working like a dream, both server side and client side validation using DataAnnotations is working beautifully well and I am nicely receiving my populated complex objects as expected in the Controller.. Now I'm trying to save.. The Employee should always be newly created, because its an "Add New Employee" form. But sometimes the Address is an existing Address and I don't want to insert another one. Rather, I just want to link the Employee to the existing AddressID of the one that already exists in the database.
So I wrote a nifty GetExistingOrCreateNewAddress(Address PostedAddress) method which works great so I end up with the correct Address to use and link to the about to be saved Employee object. This is all happening in the same DataContext, so no problems there..
BUT even when I link the about to be saved Employee object to an existing Address, on save a new/empty Address row is created in my Addresses table. Even though the newly created Employee does link correctly to the existing Address I told it to! Why is it so??? And how can I save the new Employee without LINQ automatically creating a blank Address for me. Because I'm explicitly specifying an existing Address it should be linked to instead!
[HttpPost]
public ActionResult CreateEmployee(EmployeeDetailsViewModel NewEmployeeDetails)
{
if (ModelState.IsValid)
{
EmployeeRepository ER = new EmployeeeRepository();
// Fetch or Create the appropriate Address object for what has been entered
Address ActualAddress = ER.GetExistingOrCreateNewAddress(NewEmployeeDetails.EnteredAddress);
// Link this Address to the "about to be saved" Employee
NewEmployeeDetails.Employee.Address = ActualAddress;
// Lock it in..
ER.SaveNewEmployee(NewEmployeeDetails.Employee);

I have a multiview inside an updatepanel. in one of the views, I save a value in a session object like this:
Session["xyz"] = "some string value";
Then I switch to another view and try to pick it up the value in a button's OnClick event:
string x = Session["xyz"].ToString();
But I get a null reference error. Debugging it shows that Session["xyz"] is indeed null, yet other Session variables are still there. Is there something special about Session and AJAX?

I am having a bit of trouble trying to get teh postback data from a programmatic generated radio buttons in TableCell object. I have the following ASP user control:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wcntrlCallFlow.ascx.cs" Inherits="CallEvaluation.wcntrlCallFlow" %>
<style type="text/css">
.TableDev
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
}
.HeaderRowStyle
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
background-color:#33CCCC;
}
.DetailRowStyle
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
background-color:White;
}
</style>
<asp:Table ID="tblControl" runat="server"/>
I generate the TableRow and TableCell base off XML data file. When the submit occurs I can not access the data values from the radio buttons that are generated. I try to get the data in the following manner:
if(Request[objRadioName].Checked)
{
this.value = 5;
this.ReCalc();
}
I notice that in the Request object the table row name is passed back like: "wcntrlCallData1$wcntrlCallFlow1$CallFlow".

My problem today is that I am having trouble shifting some functionality, that is being used in multiple applications, from the applications themselves to a class library I have started building. The issue comes in the fact the code was written to utilize Response objects as seen below...
[Code]....
This is all currently within a function called "DownloadDocument". I continue to have issues running any of the Response object functionality. I usually get the error saying, "Response is not available in this context", is there anyway to use a Response object in a class library file?

There is an external (Java based ) web service that i am calling. I've added my service reference and verified that Reference.cs has been generated.
Then i call my service form my client website like such:
[Code]....
But my response object is mostly null after it receives the response. The properties that should have values do NOT.
When i look at Trace viewer, the SOAP request is correct and the SOAP response is correct. I get back a valid soap response with all the data i need it's just not making its way back to my response object. I've tried regenerating the proxy many different ways (svcutil) with no luck.
Example of what is in the response object (good data which is not making it's way back to my response object):
<ogc:Spatial_Capabilities><ogc:GeometryOperands><ogc:GeometryOperand>gml:Envelope</ogc:GeometryOperand><ogc:GeometryOperand>gml:Point</ogc:GeometryOperand><ogc:GeometryOperand>gml:LineString</ogc:GeometryOperand><ogc:GeometryOperand>gml:Polygon</ogc:GeometryOperand></ogc:GeometryOperands><ogc:SpatialOperators><ogc:SpatialOperator name="BBOX"></ogc:SpatialOperator><ogc:SpatialOperator name="Overlaps"></ogc:SpatialOperator></ogc:SpatialOperators></ogc:Spatial_Capabilities>
Why isn't the SOAP response making its way back to my response object?

I am creating a web application that allows a user to download a csv file of a gridview. However, after looking at tutorials online such as http://www.aspsnippets.com/Articles/Export-GridView-To-Word-Excel-PDF-CSV-Formats-in-ASP.Net.aspxand such, I successfully got the table I wanted but there are HTML content appended to the table as well.There was also a similar problem being brought up on the forum,http://forums.asp.net/p/1528174/3692826.aspx. The solutions didn't help me much though. However, I am not really sure how Handlers can benefit this. Furthermore, I don't want the user to be navigated to a blank page just to download the csv file. I tried to debug and insert removal code to remove the html code before the response object is being wrote out but seems even at the end of the writing method, the response object seems to be holding just the table content only.

How can I remove the html content and add new string to the Response object. If I use the Respose.Write method the page contains the string, but while taking the view source option from browser it will display some html tag like Doctype, head, body etc. My requirement is only the string should be displayed in the source.
