Tip/Trick: Increase your VS screen real estate by disabling HTML Navigation

Below is a tip/trick I twittered via my Twitter account earlier today. A number of people seemed interested in - so I thought i'd blog it here too.

HTML Navigation Bar in VS 2008
By default, when you are in HTML source-editing mode with VS 2008 and Visual Web Developer 2008 Express edition there is a set of drop-downs that are rendered immediately above the HTML text editor view:

Send mail from my application

Hi,

I have a requirement where i need to send mail from my application. I used the following code to send mail

        MailMessage msgMail = new MailMessage();
        MailAddress fromAdress = new MailAddress("praveen.k@gmail.com","Mechano");
        msgMail.From = fromAdress;
        msgMail.To.Add("praveen@gmail.com");
        msgMail.Subject = "Issue on Website";
        msgMail.IsBodyHtml = true;       
        //msgMail.BodyFormat = MailFormat.Html;         
        string strBody = "This is test message";        
        msgMail.Body = strBody;
        SmtpClient sClient = new SmtpClient("127.0.0.1", 25);
        //sClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
        sClient.Send(msgMail);

The above code is neither working in my local system not showing error, but after the application has deployed in remote server(this is shared server) the code is working. What might be the problem?

Thanks

will a 32-bit web application run as WOW64 on a 64-bit server?

I need to know if a web application deployed in a 64-bit server runs as a WOW64 process or a 64-bit process if the web application's pages are compiled as PE 32/x86 ?

I mean I have read a lot about normal console applications or executables with PE 32/x86 run as WOW64 on 64-bit servers. But what about web applications( all i can compile is the pages which are dlls)? The only process I can think of is w3wp.exe for web apps. Please explain. I am confused.

Thanks in advance

create a method similar to this

In one of our pages we are using this bit of code to check if something is null and passing in a 0 instead. This works great for this page, but this was done by another person and thye are no longer here.. so i'd like to take that idea and create something similar but return a empty string or blank space, the reason is that i have a page where you make a selection from a gridview and onselect that rows data is passed into some textboxes.. well at the moment, if you select a row and one of the columns is blank, the textbox is being populated anyway with this   so i would like to make sure that if there is nothing, that the textboxes are left blank.. since there is potential for having alot of textboxes, i would rather create a method that can do the checking instead of doing if condition for each parameter. does that make sense? If so any suggestions would be great. and thanks you

        //CONVERTS NULL VALUES TO ZERO
        protected string valid(OleDbDataReader myreader, int stval)
        {
            object val = myreader[stval];
            if (val != DBNull.Value)
                return val.ToString();
            else
                return Convert.ToString(0);
        }
        //END

Create more than 1 set of controls in runtime.

I've figured out how to create the controls in the format I want, but now I am confused as to how create more than one set of them. I set everything to new and increment the names of each control, but it's only updating the one set. Here is my code:

  intPnlCounter += CInt(ViewState("intPgCount"))
        
        'Table
        'PlaceHolder1.Controls.Add(New LiteralControl(" <table style=""height: 27px""><tr><td colspan=""2""> </td><td colspan=""2"">"))
        PlaceHolder1.Controls.Add(New LiteralControl("<table style=""height: 27px"">"))

        'Component Header
        Dim lblHeader As Label = New Label
        lblHeader.Text = "Additional Component Item: " & intPnlCounter
        lblHeader.ID = "lblHeader" & intPnlCounter
        lblHeader.Font.Bold = True
        lblHeader.Font.Underline = True
        lblHeader.Font.Name = "Trebuchet MS"
        PlaceHolder1.Controls.Add(lblHeader)
        PlaceHolder1.Controls.Add(New LiteralControl("<tr><td colspan=""2""> </td><td colspan=""2"">"))

        'Item Label
        Dim lblItem As Label = New Label
        lblItem.Text = "Item:"
        lblItem.ID = "lblItem" & intPnlCounter
        lblItem.Font.Bold = True
        lblItem.Font.Underline = True
        lblItem.Font.Name = "Trebuchet MS"
        'lblItem.Font.Size = Unit.Percentage(10)
        PlaceHolder1.Controls.Add(lblItem)
        PlaceHolder1.Controls.Add(New LiteralControl(" "))
        'Item Textbox
        Dim txtItem As TextBox = New TextBox
        txtItem.ID = "txtItem" & intPnlCounter
        txtItem.Width = Unit.Pixel(306)
        PlaceHolder1.Controls.Add(txtItem)
        PlaceHolder1.Controls.Add(New LiteralControl("</td><td> </td></tr><tr><td class=""style11"">"))

        Dim lblNSN As Label = New Label
        lblNSN.Text = "NSN:"
        lblNSN.ID = "lblNSN" & intPnlCounter
        lblNSN.Font.Bold = True

        PlaceHolder1.Controls.Add(txtNSN)
        PlaceHolder1.Controls.Add(New LiteralControl("</td><td class=""style12"">"))

        'PartNum Label
        Dim lblPartNum As Label = New Label
        lblPartNum.Text = "Part Number:"

Using VB, how do I use the For i = 1 to 10 to create a dynamic double variable

I have some global variables declared and want to access them in subrorutines using the For statement.

For example, I want to use the following to place values in the global variables , i.e, dblcell1, dblcell2, dblcell3, etc.

Dim m As Integer
			For m = 3 To 11
				If e.Row.Cells(m).Text <> " " Then
					dblCell & m = e.row.cells(m).text)

				End If
			Next

I know that I can't use the "dblCell & M". It is just to show the objective. It is where I get an error.

Thanks

Trying to create a data set that I can reuse

Hard to describe be here goes.

Currently I have this in the aspx page

<% = new BuildFormField() { FieldName = "FirstName" }%>

And the simplified object

Class BuildFormField(){

return GetFieldAttributes("FirstName") //calls a linq query based on the field name to get all the attributes of the field ie size/class and builds the html string.

}

The problem is, I will have many of these and it queries the database every time. What I would like to do is build a general dataset once and query that result set for each field.

I can't figure out where I should setup the initial query. Obviously don't want to put it in the aspx page or the controller and I can't figure out how to create a class that would only get called once that I could use again inside the BuildFormField Class.

Hope that makes sense. Yea, a bit unusual of a way to create form fields, but there is good reasons.

Thanks ahead of time.

How to remove the MY ASP.NET APPLICATION header and the login button and box

Visual Web Developer 2010 Express

Windows 7

I have chosen ASP.NET Web Site, rather than ASP.NET Empty Web Site when I created my website. I thought just a little first step would help.

I now find that I am left, in default.aspx, with this extremely annoying bold header -

MY ASP.NET APPLICATION at the top of the page, and a little login function in the top right corner.

All attempts to enter the area produce a no entry icon.

How do I get rid of / change this header area? Or did I get myself locked into this by choosing Express and/or ASP.NET Web Site rather than an empty one?

I sure do like the structuring of the forums here. I feel comfortable in this beginner's one for now, thank you. ASP.NET wise at least.

With thanks, in anticipation of an answer, please.

Is there any other idea how to fix this? I can't help this, I've googled enough.

I previously had Visual Studio 2008 installed. Now I have Visual Studio 2010 besides Visual Web Developer express 2010 installed. Can this be problem? I don't know at all what to do.

Thank for your answers.
