httpwebrequest multipart/form data boundary

Hi, I have been trying to get this to work for a few days and tried searching everywhere but can't seem to find anything about this.

I am trying to login and make a post to a site. I have no problem logging into the site, however, when I go to make a post, nothing happens. After using Fiddler and comparing the results of the webbrowser and httprequest it looks like the boundary changes at each login.

For instance it will be this one time:
Content-Type: multipart/form-data; boundary=---------------------------7d829cb4c0502

and then it will be something like this (just slightly different) the next time:
Content-Type: multipart/form-data; boundary=---------------------------7d82b824c0502

I am trying to figure out how to get this information from the headers. Here is part of my code

<code>

httpWebRequest myRequest =(HttpWebRequest)WebRequest.Create(urlUri);
myRequest.CookieContainer = cookies;
myRequest.Method = "POST";
myRequest.AllowWriteStreamBuffering = true;
myRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)";
myRequest.Referer = "urlReferer";
myRequest.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-silverlight, */*";

Stream newStream = myRequest.GetRequestStream();

newStream.Write(buffer,0,buffer.Length);

newStream.Close();

HttpWebResponse myHttpWebResponse = (HttpWebResponse)myRequest.GetResponse();
HttpWebResponse resp = (HttpWebResponse)myRequest.GetResponse();
string[] names = resp.Headers.AllKeys;
string headerInfo = "";
Console.WriteLine("{0,-20}{1}\n", "Name", "Value");
foreach (string n in names)
headerInfo = headerInfo + <br /> + n + ": " + resp.Headers[n]; // Get the headers

resp.Close();
return headerInfo;

</code>

but this always returns

Content-Type: text/html

for the header instead of

Content-Type: multipart/form-data with the form boundary after it.

Is there anyway I can get the header information? I know it has to be possible.

Thanks

I'm not sure what you are trying to do. Is you problem in processing the response from the server? What do you get when you process the response stream? HttpWebResponse.GetResponseStream()

Thanks for the reply. I was having problems getting the boundary but think I got it figured out by using httpcontext to send the form data.

Grey Out Check Box in GridView ItemTemplate?

Cyndie4-Apr-08 8:37

I have added a CheckBox to the EditItemTemplate and ItemTemplate in a GridView TemplateField. The checkbox does not show up in the ItemTemplate unless I set Enabled to true, but when I do this the checkbox is clickable. I would like to have a greyed out, readonly, checkbox in the ItemTemplate, so the user does not try to check or uncheck it, but can see its state. Is there a way to make a readonly, greyed out, checkbox in the ItemTemplate?

Thanks!

I resolved my issue and wanted to share in case someone else encounters this. Instead of using an ASP Checkbox, I changed to an HTML Checkbox and set disabled=disabled which worked. I don't understand why setting enabled to false on an ASP checkbox didn't do the same thing, but it didn't.

P.S. I am using Master Pages with the GridView inside a Panel.

Grid alignment within table

Hi guys,

I have a table set to 100% width of the window. And style="text-align:center"
Inside the table I have a gridview.
When I view the site in IE it displayes the grid in the center of the table, but in firefox it displays the grid in the left of the table.

Does anyone know why this happens and how to get it fixed?

Thanks in advance

Yes it is a well known issue that browsers are not equal. Well known since like the very first ones.

This happens because there is a bug/feature in IE that makes it apply text alignment to block elements. Text alignment should only be applied to inline elements, that's why Firefox doesn't apply it to the grid.

Use margin-left:auto;margin-right:auto; on the grid to center it.

Despite everything, the person most likely to be fooling you next is yourself.

The grid does not have the attribute margin nor style.

Thanks for the help, I used center align on td and that worked like a dream.

Try this:

ha.ImageUrl = @"~/Membership/img/icon-calendar.gif";

Have a look at the page source to see what is been written out to the browser and verify that the path is correct.
