Asp.net - How To Change Metatags Dynamically
Jun 27, 2011
I am working on a site where the meta tags are set in a Masterpage in a section using runat="server". I can update the title, description, keywords, etc... through properties in the Masterpage code-behind, but how would I add or edit non-basic ones such as
I have tried the following, but it always returns 0 for the count.
Dim header As Web.UI.HtmlControls.HtmlHead
header = TryCast(Me.Master.FindControl("headerIdName"), Web.UI.HtmlControls.HtmlHead)
Dim count As Integer = header.Controls.Count

I have close to 10,000 serverside pages, all of thse use the same stylesheet. I have created a new serverside page which is like a dynamic menu system to help find specific pages from the existing 10,000 pages quickly and easily.
The problem is, that if the serverside pages are accessed the old way using the old menu system, they should retain their old stylesheet. however, if they are accessed via the new menu system, they should use a new refreshed stylesheet.

I'm trying to find a way to change the name of a text box if the name of the text box is first declared as such:[code]I tried the statement: Name = "SBox" & My. Settings. Row Countx but maybe this is wrong.To be very brief I'm trying to resolve this to under the following scenario:
1. Add a new text box to a tab page when user selects "add" button.
2. Each text box must be assigned a unique name
3. Data entered in each text box will be then be saved in my.settings (i.e., for each text box, there will be a corresponding variable/name to hold its text value)

In my form, there is 1 Button and 1 Label.
There is no text in Label1 right now.
I have coded the button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "1"
End Sub
End Class
Now when i run the project, i click on Button1 and Label1 has text in it "1" as it is in the code.
I want when i again run the project, the text in the label should be changed once i click Button1.

I have a label, let's call it LblA. I have a SqlDataSource, let's call it sds. Now, I have selected out and managed to get specific values using the select function. I want to set LblA's text to the value selected out of sds. I need this to occur every 5 (or as many as I specify really) seconds. I orignally used a timer object, however, for any of you who have used the timer object before, it likes to refresh the page, this makes it very hard to navigate off of the page; not only that, it's sloppy. Does anybody know a way to easilly update LblA's text from sds without refreshing the actual page.
I've read around and came to the conclusion that I need to use ajax, err... jQuery. However, I really don't know anything about the two except that they are both Javascript libraries? I need a simple way, you might even have to explain it to me like I'm an idiot.

I am using vb.net and SQL server 2005 I have a project with database classes which are generated from database objects. That is I add a dataset to the project and drag and drop a database object onto it. The problem with this is that I have to give a connectionstring which is stored in the code. This is ok while developing the application. But runtime I want to use another connectionstring, both for security reasons and because each user of the application will correspond to a database user (SQL) and shall have a corresponding connectionstring. Is there an easy way to do this without having to restore to plain all datasets and do everything myself?

Suppose I have a class that represents a product to be priced using one of a number of different pricing strategies. This pricing occurs hundreds of times per second, so to eliminate repetitive if/else statements I am instead using a delegate to launch the appropriate strategy, like so:
Private Delegate Sub PricingModel(ByVal params As PricingParameters)
Private myPricingModel As PricingModel
Private myPricingParameters As PricingParameters[code].....
But this doesn't look right to me (though it seems to work). Is there an accepted/better way of doing this? Or is this the standard way? Or is this just simply a doomed approach from the start?

I'm trying to make an application to do mathematical equations, but I also want to implement error checking. So that if someone doesn't put anything in one of the fields the output textbox will say "Error".
But the problem is that I already declared the variables I used as a numeric value, in my case decimal.
So, when I make an if statement that says if inputbox1="" then outputbox1="Error" it doesn't work.
I think that in order to get this to work I would have to have it setup so that the variable that is exported to the text property of outputbox1 could switch between being declared as a decimal or string value based on what the user put into the textboxes. But I'm not sure how to go about this. Declaring the variables inside the if/elseif statements won't work because the variables need to be declared before they are calculated within my if/elseif statements.

I am using the MS Chart control (version 3.5.0). I have added it by using the designer (drag and drop). I removed the default "Series1" from the Properties -> Series -> Collection so that the chart contains no data. I am adding the data at runtime based on a canned query to a SQLite DB. Like so:
Dim SQL As String = "SELECT * FROM ageLength ORDER BY month"
Dim cmd As New SQLiteCommand(SQL)
Dim SqLiteConnection1 As SQLiteConnection = New SQLiteConnection()
SqLiteConnection1.ConnectionString = "Data Source=" & My.Application.Info.DirectoryPath & "DataUserData.db3;"
cmd.Connection = SqLiteConnection1
[Code] .....
The data is displayed on the Chart, however, it is a Bar type graph. I set it to use the Spline type for both series.

Is there a way to change label text at run time?. I don't want to annoy users with popup. So planning to display error in a label if its text could be changed.
So far I have included a Main Form which has a label lblErrorFeedback which is not visible initially and I have done this but does not work.
lblErrorFeedback.Visible = True
lblErrorFeedback.Text = ""
lblErrorFeedback.TextAlign = ContentAlignment.MiddleRight
lblErrorFeedback.Text = "Error Occured"
Is there a better way to show the error with out popups?

I'm trying to dynamically change the click event of my tray icon balloon and remove it in the handler. This is the line in the handler:
VB.NET
RemoveHandler TrayIcon.BalloonTipClicked, AddressOf UpdateSite
This is the warning I get:
Quote:
The 'AddressOf' expression has no effect in this context because the method argument to 'AddressOf' requires a relaxed conversion to the delegate type of the event. Assign the 'AddressOf' expression to a variable, and use the variable to add or remove the method as the handler.
How can I move AddressOf into a variable and reference that in RemoveHandler? I can't find out how to declare a delegate.

I want to be able to hide the left hand side of the screen and right hand side of the screen at the beginning of the program.
Then when the user presses create new button the left hand side of the screen becomes available so they can create the new item. Then when they press save it comes back to the middle datagrid only.
Then I want to add an event when the double click on the datagrid row (data is programmed in to the datagrid in the code) the right hand side of the screen becomes visible then when the button allocate is pressed the right hand side disappears again just leaving the datagrid.

I use an SQL Table with (ID, Code, Comment, ..., TextColor, BackGroundColor) The TextColor and BackGroundColor are Decimal Value. I would like to do, in a datagridview, to change the font row with the TextColor Value, and the background row with the BackGroundColor. If I want to show data in textboxes, it will be the same : the font with the TextColor value, and background with the BackGroundColor value.
