without borders   

Hi.

If you have a table with some rows and columns, and set the background color on the <tr>´s like this:

table.mytable tr
{
  background-color:Aqua;
}


Then you can see the lines that seperates the <tr>´s and <td>´s. Its like the borders that define the tablestructure still has its original color (or is transparent). And it looks quite ugly. How do you avoid this? Is there a way in CSS to make these borders 0 pixels wide?

I know that I can just put the background color on the table instead, but that is not a possible solution in my case.


Thanks alot :)

Help with using a Background worker

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :WPF
 
Hi I am trying to use a background worker in my application.  I basically have a list of items displayed. When a user selects a particular item I have the background worker query the database to get information about the item selected and display it once it is done. (There are quite a few database calls) Since the database queries might take time, I have a UI wait animation displayed while the data is getting fetched. Once the background worker is completed I get rid of the wait animation and display the information fetched. This setup works fine if I do not click on any other item while the UI wait animation is being displayed. My main aim is to cancel the background worker from fetching the previously selected items information when a new item is selected (as the previous information would anyways be overwritten with the new item's information). The problem with such an approach is within the background worker's doWork method i would need to continuously check after each database query if the cancellation is pending and if it is then I can cancel the rest of the queries. I somehow feel this is not the right approach. If anyone has any suggestions about a better way to achieve the required functionality it would be great..

Open dialogue box in background worker

  
Hi, I am getting an error trying to open a dialogue box in background worker. Please help.   Imports System Imports System.Drawing Imports System.Windows.Forms Imports System.IO Public Class Form1 Inherits Form Private folderBrowserDialog1 As FolderBrowserDialog Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click bgw.RunWorkerAsync() End Sub Private Sub BGW_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bgw.DoWork Dim result As DialogResult = folderBrowserDialog1.ShowDialog() End Sub End Class

Background worker - errors in completed event

  
Create a new windows forms project (in using vb.net 2010). Create a button and a background worker on the form. Under the Debug > Exceptions menu, make sure that for 'Common Language Runtime Exceptions' you have 'Thrown' unticked and 'User-unhandled' ticked. Now put the following code in the form's code-behind; Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click BackgroundWorker1.RunWorkerAsync() End Sub Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork Threading.Thread.Sleep(2000) End Sub Private Sub BackgroundWorker1_RunWorkerCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted Dim X As Integer X = 5 / X End Sub End Class Why does it not error nicely? It comes up with no helpful stack trace and just says 'Exception has been thrown by the target of an invocation.'. Place the code to cause the error into the Button_Click event and run it and you will see the difference. Why do we not get these 'nice' errors given that the runworkercompleted event is supposed to be running on the main thread?

Error on datafilling in DataTable on background worker

WPF 4 with SSRS Report Viewer and long running Background Worker Dispatch task.

  

Hello,

I've recently run into an issue with with WPF 4 and the SSRS viewer control with a batch emailing application. See http://www.jenasysdesign.com.au/dnn/Blogs/tabid/71/EntryId/5/WPF-4-SQL-Server-Reporting-Services-processing-application-Memory-Leak.aspx for details of some performance profiling issues I found with this technology stack.

I've got two issues.

Firstly, I implemented a background worker process to handling looping through the 2,800 reports. I found to run the SSRS report viewer to export the report results in a slow memory leak. See Red-gate Ants memory profiler 6 image in the link above. I'm not sure what I need to do to remove weak references with this combination of technology. Any ideas?

Secondly, the following code runs on the background worker process, designed so the user can monitor the progress of the a large batch of report files getting generated.  The catch here is involves using the SSRS viewer to export a reports results requires the Dispatcher.Invoke method to ensure that ReportViewer.xaml screen gets a UI thread, but in the process it interferes with the background workers report progress methods, so the UI doesn't see the progress.

A query regarding the MSDN library background worker example

  

In the MSDN library article "How to: Use a Background Worker",

(see http://msdn.microsoft.com/en-us/library/cc221403(VS.95).aspx),

the following sample code is presented...


Private Sub bw_DoWork(ByVal sender As Object, ByVal e As DoWorkEventArgs)
    Dim worker As BackgroundWorker = CType(sender, BackgroundWorker)

    For i = 1 To 10
        If bw.CancellationPending = True Then
            e.Cancel = True
            Exit For
        Else
            ' Perform a time consuming operation and report progress.
            System.Threading.Thread.Sleep(500)
            bw.ReportProgress(i * 10)
        End If
    Next
End Sub

For what purpose has the "Dim worker as..." statement been included in this code?

How to pause resume Background Worker Thread?

  

We are working on a VB.Net window based application and we are using Visual Studio 2010 Professional.

In our application during the execution process we have used Background Worker thread and user have the option of cancelling the execution only.

Now we came across a situation that if user wants to pause the execution process then how we can pause the background worker thread so that it can be resumed on resuming the execution by the user?

ASP.NET Architecture - ASP.NET Worker Process - HTTP Pipleline - Http Modules and Handlers

  
"ASP.NET is a powerful platform for building Web applications, that provides a tremendous amount of flexibility and power for building just about any kind of Web application. Most people are familiar only with the high level frameworks like WebForms and WebServices which sit at the very top level of the ASP.NET hierarchy. In this article I'll describe the lower level aspects of ASP.NET and explain how requests move from Web Server to the ASP.NET runtime and then through the ASP.NET Http Pipeline to process requests.

Alternating row background for first column of a report

  

is there a way to make the first column of a report use the an alternating background color? 

I have the background color set for the entire row however it does not work for the first column if the color is set to an expression.  If I just set it to a color i.e. red it works just fine. If I insert a dummy column to the left it works just fine (but the dummy column does not work, presumably because it is first??).

In the file below only the textbox for part number does not show an alternating background.  All others work correctly.

<TableRows>
            <TableRow>
              <TableCells>
                <TableCell>
                  <ReportItems>
                    <Textbox Name="PartNumber">
                      <rd:DefaultName>PartNumber</rd:DefaultName>

Advanced Basics: Scaling Up: The Very Busy Background Compiler

  

One of the features that distinguishes Visual Basic® from the other languages in Visual Studio® is its use of a background compiler (BC). The BC runs from the moment you start up a Visual Basic project until the time you close the last one down.

BITS: Write Auto-Updating Apps with .NET and the Background Intelligent Transfer Service API

  

Both the .NET Framework and Windows have some very interesting APIs for creating applications that are capable of updating themselves automatically over a network. There are many advantages to writing your application to update itself like Windows Update does, including convenience for your users, from easier maintenance to network administration. Automatic updates require attention to factors such as discovery, security, and file replacement. In this article, the author covers the BITS API as well as a number of features of the .NET Framework that take care of these facets of auto-updating using the same facilities that the Windows Update uses.

Setting webpage/masterpage background...image?

  

I want to have the background of my masterpage (the master page for all of my .aspx pages) have a sort of gradient.  I imagine the only way I can do that is with an image.  Or maybe even some other design, but I want to move away from the "solid color" background.

Is the easiest way to do this just to make an image and set that as the background?  What image size should I make it, because some users could possibly have the normal aspect ratio, or maybe a widescreen?  What should I make it like so that it looks good on all computers?

Thanks in advance. :)

Is it possible to change the title bar background and the font style on default template?

  

Hello,

Is there any way to change the default top link /title bar picture and the fonts of the title without breaking anything in the layout/structure?

I have changed the theme to Obsedian and I would also like to change the picture of the title bar of this theme and also the font/style of the title, top link bar, menus..etc. Is there a way to do this?

Please note: I am using WSS 3.0 and I am not the Administrator of the sharepoint. I am only the site admin of some sites on this sharepoint. I can do some basic customization using SPD.

Basically, what I am trying to do is that I want to set up a sharepoint site, however I want to make it NOT look like a sharepoint site.Well I know this is possible, but for my case it might be just partially possible due to the limitation that I am not the Site collection admin and hence I do not have direct access to the server itself.

What I want is to hide most of the sharepoint links/menus/bars, etc and use my own buttons/hyperlinks etc .. for user to navigate on the sites.

Thanks in advance for your help/advices.

Regards

Rooven
