Display Animated GIF In ASP.NET Page While Executing Web Service?
Feb 21, 2012
I have a page that allows users to "upload" a file. The page includes an asp.net fileUpload control. However, all it does is send the byte array to a WSE 2.0 web service. I can't change this. This may be updated in the future, but for now, this is what I have to go with.The page has an animated gif that starts when the user clicks the submit button. And the page should be updated accordingly based on the result returned by the web service call. I'm able to start the gif and consume the WS successfully. However, while the page is hitting the web service, the gif file freezes.
I then tried to use a separate thread to consume the web service. This speeds up the process and does not freeze the gif, but the page is not updated when the web service completes. If I put the main thread to sleep, the page updates, but I'm back to the same issue mentioned above, where the gif freezes. I'm pretty sure I could make the call using javascript and update the page that way, but at this point, I'd really rather do it server side (out of stubbornness if nothing else).

I was wondering if there is a library or code snippet available for .NET (or that I can translate to .NET) to display animated PNG files (on the Graphics object, or even in a custom control)?

I am writing a service (service.exe) which I will be installing multiple times on a server with different display names (service1, service2,... servicen).Based on the display name the service will perform slightly different operations (e.g. monitor a different COM port).How can I programmatically determine the display name to find out which instance is executing?

I've got an application (that is targetting .Net Framework 2.0) that is running on startup of the System, and I'm trying to get a NotifyIcon to display.When my program starts up when a user either Runs it normally or is started as a child process after the system has already logged on everything is fine.
If my application starts up as the system is performing an AutoLogon using POSReady2009 (basically XP with Single User set). Then the NotifyIcon never becomes active.If you subsequently check (in a timer) the .Visible of the Icon at any point later it always reports that it is visible = true.If you disable the SSDPSrv and restart the Computer, the Icon displays correctly.I have a sneaking suspicion this is related to .Net 3.5sp1 installed over the top of a .Net 2 system.Is there some process that I should be following to ensure that my NotifyIcon is always available to the user.I have setup RegisterWindowMessage("TaskbarCreated") but I don't get this message called, except when you forcilbly Kill Explorer.exe and restart it. Even so, a NotifyIcon interally registers for these notifications anyway, so it shouldn't be required.I'm happy to stall the startup of my program, but once the program starts up, I expect that the icon shows correctly.

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I make a panel visible that has a tab control on it.
The panel becomes visible - I can see all three tab pages.
But the contents of the tab page is blank - until I actually click a tab heading.

I have a tab control with 4 tabs. At form load time I determine which tab I need to have the focus (which one to select). I have tried using TabControl.TabIndex = 2 to set the desired index and TabControl.SelectedTab = TabControl.TabPages(2) as well as TabControl.SelectTab(SoftwareUpdateTabPage), however, none of these seem to work at load time. The tab enter of the first tab always seems to be called. Is there a way for me to select the tab I want in my form load function?
The second part is how do I disable (so the user cannot change to another tab) the other tabs at form load time?

I am just making the switch from WebForms to MVC and would like to ask what are the best ways of hiding particular fields in the view. Assuming we have a model named WishList that has a list of gifts kids want for Christmas and the child's name. We want the elves to view the list of gifts, but only Santa Claus can view the child's name. Would it be best to have two views for the WishList (one for Santa and one for the elves) or is there another way to handle this? My concern is that the number of views can start piling as high as the snow does in the North Pole by the time I enforce all of the visibility settings required in my application.

I have created a windows form application which goes through Internet Explorer index.dat files and extracts various information (URL's , date they were last accessed etc). I then display this information in a data grid view. From here i would like to be able to click on a URL link and open the web page without activating any active content (such as java script, activex, viruses etc). I have tried to do this using Internet explorer in 'offline mode' with the problem being if the web page requires an online connection it automatically changes Internet Explorer from 'work offline' to online mode. Is there a way around this problem? Or does anyone have any suggestions on a better way to view the web pages with no active content?

A few years ago, I remember seeing an MS Access application where the programmer displayed the first page of a Word document as a thumbnail on a form. I'm guessing that its highly possible that this is well within the limits of .NET - could anybody point me in the right direction to read-up on how I might do this?

Using a session variable in my VB.net site has been figured out just fine. I just need to get my welcome message to stay put on every page. I put the code and text box in my master page to allow the message to stay there, but my label with the user's name disappears when I click on a different page.
The session is still there because I have it set up to display the textbox to enter your code if the session is destroyed or not available for some reason.
my code is not allowing the First_Name and Last_Name of the user's session to show up? The problem is in the Page_Load but I thought I would throw in the whole master.vb file to show everything I have so far.
Partial Class MasterPage
Inherits System.Web.UI.MasterPage
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have a working code that exports the datagrid into XLS. However, the datagrid results does not show on my aspx (html) page. It only shows on the page when I comment out the part that exports it to xls. I am not sure whether it should show by default when exporting.Basically, what I want to have is when I click my export button, it should display the datagrid on the page as well as popup an excel "open, save, cancel" window for the export.
Here is my function for referece:
Public Sub Convert(ByVal ds As DataSet, ByVal Response As HttpResponse)
Dim attachment As String = "attachment; filename= ExportPRFs_" & Today() & ".xls"
