Easiest Way To Securely Transfer Data From One Web To The Next?
May 21, 2010
I have 2 web sites running on the same server. Web1 needs to transfer data to web2 (same web server, different webs), passing sensitive data from one to the next. The browser will be using https. Are cookies possible/advisable here? My initial thoughts where to encrypt the data and pass through the querystring, both sites using a shared key. Perhaps also pass an encrypted expiration date to prevent the url from being reused in history if it's on a shared computer. Figuring it's https and encrypted, initially it sounds ok. However, my gut tells me its unsecure. Another option is a session server but that seems a bit overkill for what I'm after.
What is the best way to securely transfer a single piece of data from 1 site to the next on the same web and do it relatively simply?

I'm building a website for a client on which they want site visitors to be able to fill out a form with the relevant information along with their credit card details, and when they submit the form, the information will be sent to the client in an email. This is an experimental services that they're offering so they're not interested in real time credit card processing yet. If I just zip the collected data up into a password protected zip file, and send that in an email to the client, would it be secure? Or do I have to go further than that to secure the data?

What is the easiest way to save form data and retrieve it when the user navigates back to the page?
We have an application process that consists of several web forms. If the user clicks to go back a step we would like to auto-populate the fields. I am assuming there is a common generic way to do this without having to mess with individual controls - what is it?

I have a class which implements IHttpHandler that is designed to handle image resize requests. It handles Urls like so [URL] Currently the handler looks for myimg.jpg on disk, cuts a 100x100 thumbnail (if it isn't already present) and redirects the client to the thumbnail like so Response.RedirectPermanent("/some/virtualPath/to/thumbnail.jpg");
This has been working great, but I would like to avoid forcing the client to issue a second HTTP request. Is it safe to do the following? Server.Transfer("/some/virtualPath/to/thumbnail.jpg") All the MSDN documentation talks about using Server.Transfer() to redirect to an aspx page, so I'm not sure if this is the right thing to do or not.

I'm migrating from the website model to the web project model. In the past I used ssl/ftp (server is IIS7) to upload a website. The host (DiscountASP.NET) using VS2008 Publish to upload a project. VS2008 displays the alert that the password will pass in the clear. So ... what is the best practices approach to publishing a project?
1. SSL/FTP (not sure of the implications re: site compilation)
2. VS2008 Publish
3. VS2008 Web Deployment Projects

I have M:PDF-ImagesList-PDF drive on the Server with thousands of images stored.
On the M drive has folder:
M:PDF-ImagesList-PDF45404539532.pdf
4539533.pdf
4539534.pdf
4539537.pdf ...
How to access to the folder drive by using VB.NET or C# in the code-behind (securely: with username and password) for the users to be able to view images on the popup window?
See the code :
Protected Sub BtnServerDrive_Click(sender As Object, e As EventArgs) Handles BtnServerDrive.Click
Dim PartNumber As String = txtPartNumber.Text.Trim()
'Calculate the folder 4540 like container
Dim NumContainer as string = txtPartNumber.Text.Trim()
NumContainer = (txtPartNumber.Text.Trim / 1000 + 1).toString.Split(".").First
[Code] ....
How to achieve this results to access to the server drive to get images for view by using VB.NET or C# in code-behind. Servermappath, UNC, or else?

I have a CMS page that allows the user to paste in or type HTML code into a TextBox in a FormView, then do an INSERT or UPDATE operation to an nvarchar(MAX) column in an SQL table. This is using an ObjectDataSource that refers to an insert or update method in a TableAdapter in my dataset.
When testing, the server initially warned me when I tried to input or update text containing HTML code; so I set the validateRequest="false" in my page header.
I gather this can be a serious security risk. What's the proper way to "validate" the string being input? Am I opening the database to SQL injection?
Only the site administrator has access to the CMS, but malicious could theoretically bust their way in...

What's the easiest way to convert a BMP file to a single page PDF using ASP.net? I'm going to generate the 8.5" x 11" BMP in Flash (which means I can manipulate it to make it as easy as possible), then use a POST to upload it to an ASP page, which will convert it to a PDF and redirect the user to the PDF. I don't want to add any margins or anything else, it will be laid out properly in the BMP for full-bleed.Would it be easier to convert it to PDF in Flash, then upload?

var clear="js/clear.gif"; //path to clear.gif
document.write('<script type="text/javascript" id="ct" defer="defer" src="javascript:void(0)"></script>')
This file has the name js/unitpngfix.js*...i tried to see if it is being used anywhere. Yes, it is being used and all the pages that use this will not be shown as https. In the Master page, it was used like this

I want to reliably and easily Uri encode paths such as "/folder/foo%bar" to "/folder/foo%25bar".
I would have hoped that HttpUtility.UrlPathEncode would do the trick but this method only escapes spaces. I don't want to url HttpUlity.UrlEncode as this will encode "foo bar" to "foo+bar" - which ain't what I want.

I have one page with 3 FormViews + 3 Modal PopUp for them (AJAX toolkit). Works great but I have dependancy. If add a new record in one modal pop up it should be available in another one. I use autocomplete which does the work the problem and I have a hidden combo box where I get the ID for the insert.
Problem? The problem is that when I insert new record it doesn't update the asp combox box (not AJAX) so I cannot get the new id.
What would the easiest way to get ID without doing post backs. I want to avoid post back because the entry in text box might not be valid (partially typed) so I want to make sure it is typed in full so it I can get unique row = ID.

I have a datagrid with sorting. I set enable sorting to true, but that makes every column sortable. Is there a simple way to make it so that only one column header can be clicked for sorting? I feel like there should be a simple and quick fix for this, but who knows. some code:
<asp:GridView ID="ProductsGrid" runat="server"
AutoGenerateColumns="False" Height="323px"
style="margin-top: 23px; margin-left: 0px;" BackColor="White" CellPadding="0"
Width="1210px" OnPageIndexChanging="gridView_PageIndexChanging"
onrowdatabound="ProductsGridView_RowDataBound" AllowPaging="True"
PageSize="25" AllowSorting="True" OnSorting="ProductsGrid_SortCommand">
I then have several columns. Is there something I can set in the code for the column to disable all others or only make one sortable?

What is the easiest way to include a tooltip in the gridView column?
For example in this column
<asp:BoundField DataField="short_comment" HeaderText="Comments" ReadOnly="True" SortExpression="short_comment"/>
I would like to have something like
<asp:BoundField DataField="short_comment" ToolTipDataField="longer_comment"/>
Obviously the ToolTipDataField does not exist, but what would be the easiest way to achieve that functionality?

I now that I can just define the width and height of a page with the div tag to allow for dragpanels to work, but it messes things up with some browsers when rendering, sometimes shrinking the actual content to allow for the complete page and width to be shown such as on the IPAD. I have tried the Javascript below, but it doesn't work, and whenever I try to resize a page manually, it puts my computer into never never land.
Anyone have a clean Javascript that will change the width and height dynamically as I am moving a dragpanel.
I can move the dragpanel, but it snaps back as soon as I let go so in essense it doesn't work.

I have a selection list that is generated dynamically, it lists a number of checkboxes that are based on an end-user editable table, as such I have no idea what data, or how much, might be contained in this table and how many checkboxes or what they might contain, other than the primary keys of the table. The user will select the checks they wish to see, and then control is passed to another page via PostBackUrl. The second page has to figure out which records to show (build it's where clause) based on the checkboxes checked in the previous page.
So, my problem is several-fold. First, asp:CheckBoxes don't have values. This can be worked around by a number of methods. Right now, i'm using a placeholder and dynamically creating the checkboxes in the ItemDataBound event of the DataList. I set the ID to "CheckboxKey1Key2" (where Key1 and Key2 are the primary keys of the check items). Second, I have to walk through the controls of the PreviousPage to dig out all these values. That in itself is also a pain, but doable. Now, my thinking is to build the where clause of my Linq2Sql query based on the keys I got from decoding the checked checkbox names. This all seems like a lot of jumping through hoops for something that shouldn't be this difficult. Am I missing something? Does anyone have any better solutions?

We are developing SOA based application using .NET 3.5 and WCF & WPF.
One common issue we are facing is mapping between WCF enum and WPF enums. We had to do mapping between WCF enums to WPF enums. Following is sample code
Switch(WCFServiceObject.Status)
{
Case WCFServiceStatus.Married[code]....
You can see that we have to do mapping WPF and WCF enums. Is there any easiest way to achieve this mapping without writing tedious switch statements? One way of doing this is using Dictionary, but apart from this, is there any good way? We have lots of enums for which have to do mappings.

I have this code
private void BindSecondaryGrid()
{
DataTable dt = (DataTable)ViewState["SelectedRecords1"];
gridview3.DataSource = dt;
gridview3.DataBind();
}
The selected records from the gridview2 are saved there ViewState["SelectedRecords1"].The columns are id, name, quantity, total. Then these records are saved in gridview3 with
gridview3.DataSource = dt;
gridview3.DataBind();
Now i would like to get these values from gridview3 and store them in a table in my database with same columns of course.Is there a way to do that?

I'm implementing the MVP pattern within an existing asp.net webforms application and I was wondering if there is a clean way to map my form data to a data transfer object. I'm not particularly fond of implementing it this way:
MyObject obj = new MyObject()
{
bj.Name = txtName.Text,
obj.Description = txtDescription.Text,
obj.SomeOtherValue = txtOtherValue.Text
};
