We have a Citrix .ica file icon that will be placed on a web page. Is there a way to detect if a pc has the Citrix client installed?
Our end goal is to display a message at the bottom of the page with a link to install the Citrix client from our network share. But we only want to the message to display if the client pc doesn't have the Citrix client installed.
I tried to install MVC2 RC AspNetMVC2_RC_VS2008.exe [URL]? aiming it to use from VS2008SP1(Windows XP Pro SP3) but initially I got an error: Component Microsoft ASP.NET MVC 2 has failed to install with the following error message: "A different version of ASP.NET MVC 2 is already installed on your system. Please uninstall this version before proceeding with this install." The following components were not installed:
- Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools The following components failed to install:
- Microsoft ASP.NET MVC 2
By my distraction in "Add/Remove Programs" I deleted the entry "Microsoft ASP.NET MVC 2" instead of
"Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools" (told me by error text) and then succesfully installed
AspNetMVC2_RC_VS2008.exe Now I see entries in "Add/Remove Programs":
- Microsoft ASP.NET MVC 2
- Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools
- Microsoft ASP.NET MVC 2 - Visual Studio 2010 Tools
Well, it was the same before uninstall/install. I know that only MVC2 Preview can be used with VS 2010 and I gues that I uninstalled MVC2 Beta that was installed before for VS2008. Now I am in doubt: Had I installed MVC2 RC or what do I have with VS2008? How can I determine/check which release of MVC2 is installed with Visual Studio 2008 SP1 (or VS2010 Pro Beta 2)?
I have winxp sp3 home ed. I have installed vs2008 and sp1 and verified this. I tried to install sql server 2008 and keep getting an error saying cant continue because A previous release of Microsoft Visual Studio 2008 is installed on this computer. Upgrade Microsoft Visual Studio 2008 to the SP1 before installing SQL Server 2008. vs2008 SP1 is installed and why isnt this been detected ? I read I need to I read I need windows installer 4.5 but I have already installed this.

I am developing a web application in vs.net 2010 using asp.net 4.0 in c# and using IIS. Application is running success fully in local host and server. when run application without IIS in local host then I get all printer name ( installed and also not installed).
but the problem is that when I run application with IIS in server then application running successfully but I am not able to add printer name in drop down list of client computer.
I have a c# website that allows a client to connect directly to a remote SQL Server database from their PC, bypassing the web server, by using a 3rd party ActiveX control. I was originally using the SQLOLEDB provider and it was working fine. The clients are in an internal network (using Windows machines and Internet Explorer) and the website is not intended for exposure to the general internet.
I had to upgrade from using the SQLOLEDB provider to the SQLNCLI10 provider to cater for the new datatypes in SQL Server 2008. It worked on my PC, but broke in production. What I didn't realise is that it worked because the SQLOLEDB provider is part of the Windows OS (MDAC/WDAC) so already exists on the client's PC. The SQLNCLI10 provider is included as part of SQL Server 2008 and has to be installed separately on the client machine (because most of them won't have SQL Server installed, but I do).
I can provide a link for them to download a standalone Microsoft SQL Server 2008 Native Client provider from, but how do I check if they already have it installed?
Does the client require the .NET framework to be installed to run an ASP.NET application that is using the report viewer control? It is my understanding that all ASP.NET web applications can be run from any machine and that the .NET framework only needs to be installed on the server where IIS is running. Is this correct?

View 5 RepliesI implemented a chat using the COMET "way" described in this article: http://www.codeproject.com/KB/aspnet/CometAsync.aspx
In this example, the client connects for 5 seconds every time. I wanted to hold the client longer, for about 10 minutes.
My problem is - how to detect if the client disconnected during those 10 minutes? I tried using Response.IsClientConnected but it returns true even if I close the client. There must by some inidicator since the socket gets disconnected if I close the client.
i want to show info like how much time will be requited to download file in client machine. every client will have different internet speed so how can i detect and show time required to download file in client machine. is it possible in asp.net.
View 2 RepliesI have a web form which does a full page postback when a button is clicked. This is caused by an update panel trigger. Client-Side: When the button is clicked, an animation gif is displayed Server-Side: When the button is clicked, the server side event changes the content type to excel, binary writes out excel content (byte array) and does Response.Flush() and Response.End() Client-Side: User is asked to either open or download the excel file. Animation gif is still displayed.
Question: How can I detect client side (using jQuery or Ajax) that the response has been completed. There is no page postback because the code-behind has cut off the response by using Response.End().
I'm trying to prevent a "flicker" effect that is occurring on my ASP.NET page which occurs when a user navigates to the page via the browser back button after having navigated away from it. The reason for the flicker is that I'm using an Update Panel which has some content in there on the initial page-load. As a result, when the page is loaded via a back button that initial content is shown very briefly before it is updated with the correct History-aware data.
In order to overcome this I am intending on having the updatepanel hidden (display: none) on inital page load and then show it as long as we don't have any history to deal with. The problem is that I can't find out what to check to determine if there's any history. I can see that the Sys.Application has a _history member but when I'm checking it on page init it is null each time.Does anyone know what I should be checking to determine if there's history to deal with for a page load client-side? And at what point to do it?

View 4 RepliesI know this is probably a stupid question and/or has been asked before, but.... I've search through the forum and Google to no avail. I have access to a Windows Server 2008 Standard SP2. It is running IIS 7 and has ASP.NET Frameworks 3.5 SP1 installed.
I have no problem running either Classic .asp pages, Html pages or ASP.Net Webforms. However, when I try to upload and run a MVC application, I get error:Could not load file or assembly 'MvcApplication1' or one of its dependencies. Access is denied.
My question is and I have not been able to find any references online, but does the ASP.NET MVC 2 need to be installed on the Server, like it does on my devopement machine that I'm using VS 2008? If so, what exactly needs to be installed on the server to get the MVC applications to run?

View 2 RepliesPretty much what the title says really, I followed the instructions on the orchard project website to install v0.9 with the web platform installer. No error whatsoever until I tried to access it with my browser, when I just got an error 500.19
I have issues finding what's wrong with my install as IIS/ASPX error messages are less than explicative (at least compared to apache/PHP), and enabling error logging leads to the creation of 200+ kb XML files where I can't seem to find anything that points me in the right direction for troubleshooting
where I might start looking for what's wrong? Even better, any known installer issues with orchard 0.9?
EDIT:
Error given is:
Compiler Error Message: CS0234: The type or namespace name 'WebData' does not
exist in the namespace 'WebMatrix' (are you missing an assembly reference?)
Line 25: using WebMatrix.WebData;
So it's missing an assembly - how can it be that it's missing Webmatrix.Webdata if the previous line is using WebMatrix.Data and it gives no error there?
Just trying to download it from [URL] for the first time. Web Platform Installer says regarding "Frameworks and Runtimes" (and also "Visual Studio Tools"), "All the recommended products from this group are already installed", even though they're not. Did have something called Visual Studio Runtime Redistributable installed which is just a handful of DLL's. I uninstalled it though - made no difference. Also removed entries from registry with "Visual Studio" in them, also made no difference.
