How To Determine Corresponding Field Names Of Items In Request.Files

Sep 15, 2010

Given a set of uploaded files in Request.Files, how do figure out which form field yielded which file?

I have a generic form emailer that various forms post to. This file generates an email of the name/value pairs contained in the form post. I'm trying to add support for uploaded files such that the table of name/value pairs will show the name of the file upload element and the name that the file was saved as.

However, I can't figure out how to link that information together. HttpPostedFile doesn't contain any information about the HTTP request (like which field name was used), and Request.Form doesn't contain any entries for uploaded files.

So while I can easily upload the files, I don't have an easy way to generate an email saying "this uploaded file was for this field, and this uploaded file was for that field".

Determine If A HTTP Request Is A Soap Request On HttpApplication.AuthenticateRequest

Jan 21, 2010

I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.

public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.
<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]

Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).

Determine Name Of Compiled Dll Files From .cs Files In Project?

Jan 7, 2011

I am doing a code review of a web project and want to make sure I have all the compiled dll's. I was provided only three .dll files for static analysis but wonder if I am missing any because when I looked at the actual code base and project it contained 20 various .cs files.All that I have opened shared a single namespace, but what was odd was the namespace was not the name of any of the .dll files. How does .net compile the application in the dlls that are found in the /bin folder? how does it get the names of the dlls? How do namespaces fit into this?

How To Determine If A Request Is The Result Of A Postback

Aug 5, 2010

I'm implementing a custom page caching solution and I don't want the request to be cached or retrieved from the cache if it's in response to a form submission or some sort of postback.I'm trying to figure out if the current HttpRequest is a postback. Is there a way of doing this outside the context of a page or other usercontrol? In otherwords if I'm inside an HttpModule I don't have access to this.IsPostBack but I still need to determine if it is in fact a postback.

How To Determine If Web Request Is To A Resource That Allows Anonymous Users Or Not

Jul 23, 2010

I have denied anonymous access to the entire application using the following Web.Config setting:

<deny users="?" />

Then, for various paths, I have allowed anonymous access using Web.Config settings such as this:

<location path="Home/ShowLogin">
<allow users="*"/>

I'd like to be able to determine during the processing of a given request whether the requested URL is to path that allows anonymous users or whether the request is to a path that denies anonymous users.

What is the most elegant way of determining this?

Configuration :: ResourceManager And Resx Files - Files To Display Items In Multiple Languages

Oct 13, 2010

I have an application that uses resource files to display items in multiple languages. My app uses quote a lot of javascript and the alerts need to display in the local language. To do this, I have created an http handler which will read the keys and values of the culture-specific resource file and write them to a JSON array which is then embedded in the page in a script tag, the messages can then be accesses using, for exmaple:

Message.Error (en-GB = "Error", fr-FR = "Erreur")

The messages http handler works great in development, however when I run the application on a test server, I get the error: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Resources.Alerts.resources" was correctly embedded or linked into assembly "App_GlobalResources.b0n9j90e" at compile time, or that all the satellite assemblies required are loadable and fully signed. The code that I use to acccess the resource file is:

ResourceManager manager = Resources.Alerts.ResourceManager;
ResourceSet resourceSet= Resources.Alerts.ResourceManager.GetResourceSet(Thread.CurrentThread.CurrentCulture, true, true);

Where Resources.Alerts is the type that contains my multi-lingual definitions. The build action for the Alerts.resx file is set to "Embedded Resource". Any ideas why this works locally but not on my test server, am I missing something?

Forms Data Controls :: How To Get Gridview Field Names

Jan 17, 2011

I have a gridview that is dynamically created based off a csv file I'm importing.

Since I don't know what the column names are ahead of time, I can't pre format the gridview and use the "findcontrol" method to get the text value of the labels that are populated b/c I don't know the column names.

I know I can get the row index like this by iterating through the gridview...


but I'm not sure how to get the text value of the first column label? Not sure of the syntax?

C# - How To Use Lambda Expression To Select Different Fields From Field Names

Nov 18, 2010

I need to get two fields from a database table (retrieved using linq-to-sql), one field is a datetime (and is a fixed field) and the other is always a decimal, but the field can be different.

The table holds currency data which is processed twice a day and in different currencies so could have fields such as AM_USD, PM_USD, AM_EUR etc. And I need to get data such as a list of the date against PM_USD or the date against AM_EUR.

I would like to be able to call the data using a lambda expression for example (this is a stripped out example):

data = TableData.Select(x=>new {x.DateTimeAdded, x.[**field name as string**]});

I have been trying to write a function to do this, and am failing dismally.

The closest I have managed is:

private Func<TableData, KeyValuePair<DateTime, decimal>> CreateSelect(string FieldName)
var parameterExp = Expression.Parameter(typeof(TableData), "sel");
var dateParameter = Expression.Parameter(typeof(DateTime), "DateTimeAdded");
var fieldParameter = Expression.Parameter(typeof(decimal), FieldName);
ConstructorInfo constructorInfo = typeof(KeyValuePair<DateTime, decimal>).GetConstructor(new[] { typeof(DateTime), typeof(decimal) });
NewExpression constructExpression = Expression.New(constructorInfo, new ParameterExpression[] { dateParameter, fieldParameter});
var lambda = Expression.Lambda<Func<TableData, KeyValuePair<DateTime, decimal>>>( constructExpression, parameterExp);
return lambda.Compile();

Which fails with "System.InvalidOperationException: Lambda Parameter not in scope".

I'm sure I missing something obvious, or going about it wrong way.

ADO.NET :: How To Replace The Field Names In SQL Query String With Variables

Aug 17, 2010

How can I replace the field names in sql query string with variables like:-

string field1="ID";
string field2="Name";
sql = "Insert into [Sheet1$] ('" + field1 + "','" + field2 + "') values('1','abc')";

I am inserting data into an Excel document which has got nearly 100 columns.

I am inserting data using OLEDB as follows:-

System.Data.OleDb.OleDbConnection MyConnection ;
System.Data.OleDb.OleDbCommand myCommand = new System.Data.OleDb.OleDbCommand();
string sql = null;
MyConnection = new System.Data.OleDb.OleDbConnection(connectionstring);
myCommand.Connection = MyConnection;
sql = "Insert into [Sheet1$] (ID,Name) values('1','abc')";

DataSource Controls :: Storing Required Field Names In Web.config?

Feb 2, 2010

I am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.

The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.

I would like to do this in the web.config so we could add/remove columns without having to redeploy.

For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.

web.config would have this entry:

<add key="Stage1Fields" value="name, id, phone"/>

Use ITextSharp To Determine Text Field's Maximum Number Of Characters Allowed?

Oct 6, 2010

I have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. Is there a way using iTextSharp to determine this setting? Here's the code I have so far:

Dim inputFields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
For Each key As String In inputFields.Keys

DataSource Controls :: Take Names From The Table And Do Another Select Based On That List Of Names?

Jun 1, 2010

I have been working with this database for some time. Here is the situation...

I inherited a MS SQL database that has hundreds of tables with similar data. For instance:

FordTampa_customer is a table,

ChevyAtlanta_customer is a table, etc....

All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...

So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.

All right, on to the real point of my post...

Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.

I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:


I am not sure how to take those names from the table and do another select based on that list of names.
