.Net's System.Web.HttpUtility class defines the following function to parse a query string into a NameValueCollection:
public static NameValueCollection ParseQueryString(string query);
Is there any function to do the reverse (i.e. to convert a NameValueCollection into a query string)?
Uri uri = new Uri(redirectionUrl);
NameValueCollection col = HttpUtility.ParseQueryString(uri.Query)
uri.Query is already decoded - so is there any way I can prevent ParseQueryString decoding it again?Apart from that - is there another method to retrieve a name value collection from a Uri without modifying any components?
I have this string test = HttpUtility.HtmlDecode("http://test.com/Folder1/Folder2/my%20view.aspx");When I look into test it still has %20 instead of a space. Why is it not decoding this?
View 2 RepliesI have a list of character that display fine in WebBrowser in the form of encoded characters such as € � ... But when posting these characters onto server to I realized that HttpUtility.HtmlDecode cannot convert them to characters as browser did, they all become space.
text = System.Web.HttpUtility.HtmlDecode("€");
I expect it to return € but it return space instead. The same thing happen for some other characters as well.
is there any way to add HttpUtility.HtmlDecode = true in webconfig.i have 1000's of textboxes. i cannot add this all of them.
View 2 RepliesI am trying to render html encoded string that is stored in SQL Server into human readable form. The HttpUtility.Decode does not decode the text that is rendered in between the open tag and closing tag of any input tag (ie. TextBox or TextArea or Select) in my ASPX page. However, HttpUtility.Decode works fine if the text is not in an input tag. The following is my test code. For example, the value of AdmitDX field in database is "Someone's comment" which is "Someone's comment" when decoded. The first two code nuggets <%%> will show as "Someone's comment" and the thrid code nugget will show "Someone's comment".
<!-- the following two lines have html encoded text, instead of html decoded text -->
<%= Html.TextArea("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX))%>
<%= Html.TextBox("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX)) %>
<!-- the next line works fine -->
Test = <%= HttpUtility.HtmlDecode(thisTransfer.AdmitDX) %>
I have an asp.net web application. I don't have the source code. The bin contains 10 assemblies and a .compiled file. I used Reflector on the App_Code.dll and it shows me classes and namespaces and stuff, but its such a mess.Is there any way to reverse engineer this web app that won't take weeks/months to unfold? The application is pretty basic.
Note, the code is written by an engineer that left the company. We own the product.

I'm trying to enable full DNS lookup including hostname. Having trouble. I've followed the instructions here
(http://support.microsoft.com/kb/297795) with no luck. Request.ServerVariables("remote_host") still returns only an IP Address.

I've also tried using DNS.GetHostEntry(IPAddress) and the depricated DNS.GetHostByAddress(IPAddress). All I ever get back is the IP Address with no host name.

We have nearly completed an ASP.NET MVC web application running with SSL in IIS and now find that we must integrate with a third-party product that is supplied as a PHP web app running under lightppd on an alternate port, but still on the same server.
We want to make the integration appear as seamless as possible, so our initial strategy is to do all of the authentication through our application, implement a reverse proxy to expose selected features from the third-party product, and then set-up the third-party product to only be accessible from localhost and (if we can manage it) only from the user our app pool runs as. As a second layer on top of this, we plan on running the third party active content in an IFRAME, so we can surround it with our menus and headers. With the right fonts and colors, hopefully, it won't look grossly out of place.
First question: Is this strategy totally naive? Given the hand we've been dealt, is there a better one?
Second question: What is the best way to implement the reverse proxy? I was thinking of using a routing rule with an Http Handler that invokes our usual authorization just as a controller would and makes the requests to the other site, streaming out the results it receives. Is there something that already does this generically, that I can just hook up and invoke? Maybe some way to specify a controller to handle everything I need to proxy and then use a ViewResult that represents a call to an external URL I construct from the URL I received?
If I can get a few pointers on what to look for, I can trot off to the docs for the details.
i have stored in the database as location India,Tamilnadu,Chennai,Annanagar while i bind in the grid view it ll be displaying as 'India,Tamilnadu,Chennai,Annanagar' this format.
but i need to be displayed as 'Annanagar,Chennai,Tamilnadu,India' in this format. how to perform this reverse order in query or in c#
note: this is stored under one column as 'India,Tamilnadu,Chennai,Annanagar' with comma separated.
How can I do the reverse of a regular PayPal transaction. The only information I found in their documents was for the customer to pay us for things. What if we want to pay out the customer?
Is there a way to give a transaction type to reverse and pay out to the customer instead of them paying us?
Update: Turns out you can use Mass Payments to pay out to customers... just needed to look on StackOverflow a bit more [URL]
Local machine visual studio day and month are normal in format dd/mm/yyyy. But after deployed to remote web site, saved Excel using C#, less than day 12, become mm/dd/yyyy.
Actually the code is to get data into Excel from stored procedure which do pivot table The way i save date to cell is oSheet.Cells[currentline, i + 1] = String.Format("{0:dd-MM-yyyy}", Convert.ToDateTime(reader[i].ToString()));
while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
if (reader[i] != System.DBNull.Value)
{
if (i == 0)
{
oSheet.Cells[currentline, i + 1] = String.Format("{0:dd-MM-yyyy}", Convert.ToDateTime(reader[i].ToString()));
}
else
oSheet.Cells[currentline, i + 1] = reader[i].ToString();
}
}
currentline = currentline + 1;
}
reader.Close();

View 2 RepliesI have an embedded Google map with my web application in ASP.NET 3.5.I have implemented reverse geocoding (getting address from latitude and longitude) on Map click.Now, I need the same but on marker click.
View 2 RepliesAt the moment i,m working at a websit (ASP.net 3.5). I have build the project and till my surprise it is possible to reverse engineering the created dll's to the code (with Red Gate's .NET Reflector).
I have found several tools like Xheo and dotfuscator, but does there realy protected the created dll's ?? Does Microsoft have build a method to secure this ?? If this is not possible everybody can steal your code....
I have took a lot of time reading about this article, but is there a method or tool to make this secure?
What is the difference between HttpUtility.HtmlEncode and Server.HTMLEncode in c#
View 1 RepliesWe have an issue when our web application runs under reverse proxy.
The reverse proxy change the URL for the website from for example: "http://TestWebApp/" to: "http://ProxyDomain/Test/" when it runs under reverse proxy which is mapped to "http://TestWebApp/" and rout requests to it.
This raise an issue of root relative paths (paths that start with "/" to be relative to the root of the web application i.e. "/Folder1/Test.aspx"). Generally all paths that need to be rendered to client we use ResolveClientUrl method and all is good.
When using Ajax controls and ScriptManager WebResource.axd paths are rendered in script tags as a relative url paths ("/WebResource.axd?blablabla") because the root under reverse proxy is the proxy domain itself the path is useless - the web resouce is not downloaded and the application break.
To fix this we tried to set a Response.Filter in OnPreRender event handler of our base page. In our custom filter we use Regex to search and replace all "/WebResource.axd" occurences with the resolved to client root path using the ResolveClientUrl method of the page. This works great and the web resources are downloaded to client.
But this is not the end of our troubles.
In Ajax requests the response output is fixed as described but when recieved at the client end it is not valid and the partial update fails with Sys.WebForms.PageRequestManagerParserErrorException.
It fails to parse the response because the rendered response have numbers that states the actual count of bytes per rendered component (which includes the script tags referencing the WebResource.axd). The client reciever validates the recieved response according to the numbers, but, our filter altered the response so the numbers are not correct and the response validation fails.
We can try and code a smart filter that parse the response and recalculate the numbers according to the ammount of paths fixed, but I hope there is an elegant and better solution for this.
Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?

I have a simple list view that displays some text and a picture. The text is stored in the database and new text is inserted into the database through the list view. The list view displays all of the data with the oldest, or first, line of the database first. I want to reverse that by displaying the last line, or newest entry first. The site is live, and I do not know how to change the database remotely. Can I put some code on the page or code behind that will accomplish this? What is it called and where do I look?
