View 2 RepliesI would like to serialize the properties of the HttpBrowserCapibilities object so that it may be returned via a web method call. Currently the object cannot be serialized:Cannot serialize member System.Web.Configuration.HttpCapabilitiesBase.Capabilities of type System.Collections.IDictionary, because it implements IDictionary. ...which is understandable. However, I would like to simply copy out the properties and their values to a hierarchy, i.e.
<HttpBrowserCapabilities>
<IsMobile>true</IsMobile>
</HttpBrowserCapabilities>
I'm starting to think I would need to use reflection to copy this object, but I haven't reached a conclusion. Does anyone have any suggestions to keep this simple?
I am confused about how to reference objects in session, how to update, and copy.
if I create
MyObject obj = new Object ();
then
Session["object"] = obj;
MyObject temp = (MyObject)Session["object"];
If i change something on temp, will the object in session be updated? do i need to follow changes with Session["object"] = temp?
I am building an ASP.NET application that needs dynamic tables. That's another issue that I've already posted about (and gotten a pretty good response!). Now, I'm running into another issue - I want to add new rows to my table, but given that I will have 10-12 tables on one page, each containing different objects in their rows (text boxes, check boxes, etc.) I need a way of simply generically adding a new row that has the same objects as the first row in the table. Here's my code:
Private Sub AddTableRow(ByRef originalTable As System.Web.UI.WebControls.Table)
Dim originalRow As System.Web.UI.WebControls.TableRow = originalTable.Rows(1)
Dim insertingRow As New System.Web.UI.WebControls.TableRow
Dim insertingCells(originalRow.Cells.Count) As System.Web.UI.WebControls.TableCell
Dim index As Integer = 0

View 4 RepliesAm currently working on my first ASP.NET projects. I have a requirement for a page where a user can enter their current address, and then add as many previous addresses as they like. I have created a Panel with the required text boxes in, and also an 'Add' button which will allow them to add another address. How could I make a copy of that Panel and add it to the page at runtime ... assuming that it is possible!!!
View 14 RepliesI followed the instructions from the release notes, except for one thing. I did not include the following in my web.config. Thas the the "bindingRedirect oldversion 1.0.0.0 to newVersion 2.0.0.0". I got an error message to the effect that I could not have 2 configuration sections in the web.config. I was told that as long as I had the system.web.mvc 2.0.0.0 in my BIN and, I was refereincing this same version dll that I should be fine? I am wondering if I should just create a new MVC2 project and copy my MVC1 relevent files into this MVC2 project, not sure.
View 1 Replies I have created a script with pulish to provider button on VS 2010 and I need to deploy my database to my sql server.How can I do that ?
I cannot create a copy of my database on sql server with sql script file.
I have a folder on my server say:
MasterArt
in that folder there is 4 folders
pics
videos
music
other
in the pics folder is jpg's that are the buttons for a web page, the web page is in the MasterArt folder and is named default.aspx upon a user creating an account, i have my program create a folder under a subfolder named ARTIST
I got that part but now what I need to learn how to do is to have at run time, when a new user creates an account, that my program creates a subdirectory under the ARTIST subdirectory and then I copy the default.aspx from the MasterArt folder into their folder, then copy the folders and contents of the 4 subfolders (pics, videos, music, other) so that they now have the direcotries and its contents.
Example: I create a user account and my artist name is Kevin
a subdirectory is created called Kevin, the folder Kevin should now have the default.aspx page, and 4 sub folders, pics, videos, music, and other.

As some may be aware, I recently posted about high memory usage on my website and I have an idea that my thumbnailer may have something to do with this as I am not actively disposing of the instance when it has been used due to my misunderstanding how it works.
I am now looking at my code for the thumbnailer and would like some advice on when something would actually need disposing of, is it ONLY when you create a new instance of an object?
Like:
Target := System.Drawing.Bitmap.Create(Trunc(Width), Trunc(Height));
MyImage := Target.FromFile(PhotoPath);
So, my question would be, do I need to dispose of both Target and MyImage to make sure the GC does what it needs to do properly?

I have an API DLL which is a COM object. I've used this DLL in a Winforms application successfully. When I use it in ASP.NET application I get the E_OUTOFMEMORY error: "Creating an instance of the COM component with CLSID {} from the IClassFactory failed due to the following error: 8007000e" when I create an instance of the COM object.
Although I don't think it is a security issue, I've tried using windows authentication and also to give privileges to the ASPNET user with no use.
I don't have the source code of the COM object.

2) Should DTO's have their own namespace ? If yes, how do we organize them ? Each DTO inside a single class file or all DTO's inside a single class ?

how to create object of HttpResponse class
HttpResponse response=new
HttpResponse (TextWriter
tx);
how to inplement this wrong code to right one & how to implement TextWriter.
Why do we use the reference of abstract class (or base class) to create object of it's sub-class. eg: TextWriter is the abstract class for StreamWriter & StreamWriter.
TextWriter writer = new StreamWriter();
why can't we simply use :
StreamWriter writer = new StreamWriter();
