Mar 9, 2010
How can i add a progressbar to a search of a datagriview in my code :
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim nwindConn As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS;Initial Catalog=teste1;Integrated Security=SSPI;")
Dim selectCMD As SqlCommand = New SqlCommand("SELECT Username from TABELA1 WHERE Username = '" + TextBox2.Text + "'", nwindConn)
selectCMD.CommandTimeout = 30
Dim custDA As SqlDataAdapter = New SqlDataAdapter
custDA.SelectCommand = selectCMD
nwindConn.Open()
Dim custDS As DataSet = New DataSet
custDA.Fill(custDS, "TABELA1")
Dim bs As New BindingSource()
bs.DataSource = custDS.Tables("TABELA1")
' your dataset/data table
DataGridView1.DataSource = bs
usernameLabel.Text = IIf(custDS.Tables("TABELA1").Rows.Count > 0, "O utilizador já existe", "Poderá registar-se com esste nome")
nwindConn.Close()
End Sub
I have made a AutoNumber Identity Column and iset Identity Specification property to "Yes" to keep the Identity Increment and Identity Seed values as default ones.
But when i use a datagriview and use a table adapter the column don´t appear on the datagridview.
I have two pages in my website. my code is working fine. When i click on my btnpaycard then my data reach to the next page which is working fine. What i need is to display a progressbar also when I click on btnpaycard. I tried to do many tricks but nothing is working fine. I even try to display a label but that also do not get visible before the processing of the btnpayrcard.
i have 100 records to insert into DB for which i need to show the user progress of inserting records by using procress bar in asp.net by using vb.net how can i do it?
There are numbers from 1 to 100 saved in DB Table 1.There is a Gridview, which is bind from from DB table 1. Which shows all the numbers that are there in DB Table 1 inside Gridview.
Requirement is that I have to show numbers in Gridview along with progress bar.i.e.,
if number in Gridview is 1, it should show progress 1% using progress bar     if number in Gridview is is 60, it should show progress 60% using progress bar     if number in Gridview is is 37, it should show progress 37% using progress bar

I am trying to write a simple search form for our site. Here is my delima... I am trying to figure out that if there is nothing to search for in one textbox then search in the next textbox. The problem is that I dont know how to format my search string: For Example:
As a newbie coming from a Java background with tag libraries I wonder if there is a simple possibility to render areas depending on backend values.For example if I have search form I do not want to render the table for the search results as long as the user hasn't pressed the search button. Of course I can iterate over the model containing an empty list but this does not allow to suppress rendering the whole table.Using web forms I would just control the visibility of the affected tag(s) in the code behind file but how do I do this with ASP.NET MVC?Can I use a partital view for a case like this? But I think I would have the same problem. How can I determine if a partial view is rendered (e.g. the whole result table with header)?
I made a usercontrol consisting of an AJAX tab control, a textbox, and a gridview. The gridview is pulling data from a SQL database. When the gridview is outside of the tab control and I begin to enter text into the textbox, quicksearch begins to filter the information in the gridview. When i put the gridview and textbox inside an AJAX tab control quicksearch does not work. How do i need to structure the textbox and the gridview on an ajax update panel to get it to work?
i have some text boxs in a page and in the same page there will be a table 'grid' like for holding the search result.When the user start editing and of the textbox above, the search must start by sending all textboxs values to the server 'ajax', and get back with the results to fill the below grid.
Notes:This grid should support paging, sorting by clicking on headers and it will contains some controls beside the results such as checkboxs for boolean values and links for opening details in another page.
I know many ways to do this some of them are:1- updatepanel around all of these controls and thats it "fast dirty solution"
2- send the search criteria using ajax request using JQuery post function for example and get back the JSON result, and using a template will draw the grid "clean but will take time to finish and will be harder to edit later".
3- ....My question is:What do you think will be the best choice to implement this scenario? because i face this scenario too much, and want to know which implementation will be better regarding performance, optimization, and time to finish.
I have Visual Studio 2005 and 2008 installed on my machine. When I bring up the Find and Replace box in 2008 in any project the 'Look at these file types:' option is blank however in 2005 it keeps defaulting to the file type of RemoveFile. If I don't remember to clear it then it causes my search to fail. Does any one know how do I reset this value or remove this default option so the file type is not set and it looks at every file type when I search for a word.
I have a database filled with information about a bunch of different articles. I'm trying to add a search mechanisim to the site where you would type in what you are looking for, and it would search through the articles finding the most appropriate article. In my database I have a bunch of different fields that will help find the best article. For example, for each article, there is a title, description, category, a bunch of tags, Number of page views, number of votes, and the sum of all the vote scores. All this informaiton i believe can be used to gather the most relevent article based on the persons search terms. The problem is I don't know what to do with this information. What I would like to do is have a scoring system where the highest score is the first result and the lowest score is the last result. Where the first result is the most relevent.
So for example: The user types in "Korean War" it looks through all the articles, and gives all the articles with "Korean War" in the title + 1, all the tags with "Korean" or "War" + .1, then adds the number of views/1000, and then adds the average vote/4. (I just made that scoring system up on the spot, I would need to do some testing of course). Then it would sort the articles based upon the score it recieved. Is there anyway to do this with a select statement where I can run all of the calculations and then sort them with an "ORDER BY" command? Or would i have to have the server side code do the calculations store them in an array, and then sort them in the array? Or is there a better way of doing this that I might not know of (which is certainly possible).
I want to know how can I build a simple search engine which search from specific websites, for example it should search codeplex and msdn only and show the result on my page?
