Cannot Use 'using System.Windows.Forms;' In The IIS

Nov 19, 2010

I used using System.Windows.Forms; to display message (MessageBox.Show("")). When I move the same site to IIS I am getting the following error:-

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

How can I show message box after moving my website to IIS?

System.Windows.Forms.WebBrowser Inside WebForm DocumentCompleted Not Fired

Yeah some people would say "Are you crazy using winforms controls inside asp forms"... and I think they are right. But I would say.. "I'm not the only one!!, take a look" [URL] So... Doing some kind of stuff like the previous link. I did the following:

Web Forms :: 'System.Windows.Forms.TreeViewEventArgs' Is Not Defined - Warning BC40056

I have a treeview named Treeview1 with checkboxes. I want the child checkboxes to be checked if parent is checked.

I am trying to use a simple code that I found on msdn :

For some reasons I got this error and I really dont understand why:

Type 'System.Windows.Forms.TreeViewEventArgs' is not defined.

warning BC40056: Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

Web Forms :: System.Windows.Forms.WebBrowser In Web Form?

Mar 17, 2011

A requirement of a program I am making is that it can 'print' a given URL into a PDF - the server has a PDF printer installed (and is the default printer), so it's just a matter of printing the page programmaticly, and it seems the best way is to use the WebBrowser control - however, I am running into issues

[Code]....

With the above code, I get a script error 'dialogArguments.___IE_PrintType' is null or not an object' in shdoclc.dll/preview.dlg. If I have wb.Print() to somethign like wb.ShowSaveDialog() (or something like that, can't remember exactly), I notice the 'wb' object's document is a blank page, with just <html> tags and named 'about:blank'. But strangely, almost identical code (without the threading bit in the page_load method) works perfect in a normal Winforms based application.

C# - Desk Ticket System - Windows App Vs Web App

Jul 15, 2010

I want to create a small helpdesk ticket control system at work, that would allow users to enter a help request ticket; these tickets would then be assigned to a technician to work on, and the technician would mark it as "FINISHED" after the job is done. The requesting user would then be able to confirm and "CLOSE" the ticket, so that a Help Desk supervisor can keep track of response times and other stats based on the ticket details. Nothing too complicated, using .NET and SQL Server.

I am not sure if I should develop this as a Web application or a Windows application. This application would be used in the plant floor, so it would have to be easily available in the LAN. But we currently host a list of Windows applications via Citrix, so deployment would not really be an issue here. I don't really have experience creating winapps from scratch (though I've modified quite a few), but it feels like a web application would not look as "solid". What advice can readers provide that could guide me into deciding the better architecture for this purpose?

Windows Sharepoint Services - FullTextSqlQuery Document Library Unable To Find Items Created By System Account?

Apr 5, 2010

We have created an ASP.NET web app that upload files to WSS Doc Libary. The files get added under 'SYSTEM ACCOUNT' in the library. The FullTextSqlQuery class is used to search the document libary items. But it only searches files that has been uploaded by a windows user account like 'Administrator' and ignores the ones uploaded by 'SYSTEM ACCOUNT'. As a result the search results are empty even though we have the necessary data in the document library. What could be the reason for this?
The code is given below:

public static List GetListItemsFromFTSQuery(string searchText)
{
string docLibUrl = "http://localhost:6666/Articles%20Library/Forms/AllItems.aspx";
List items = new List();
DataTable retResults = new DataTable();
SPSecurity.RunWithElevatedPrivileges(delegate
{
using (SPSite site = new SPSite(docLibUrl))
{
SPWeb CRsite = site.OpenWeb();
SPList ContRep = CRsite.GetListFromUrl(docLibUrl);
FullTextSqlQuery fts = new FullTextSqlQuery(site);
fts.QueryText =
"SELECT Title,ContentType,Path FROM portal..scope() WHERE freetext('" +
searchText +
"') AND (CONTAINS(Path,'"" +
ContRep.RootFolder.ServerRelativeUrl + ""'))";
fts.ResultTypes = ResultType.RelevantResults;
fts.RowLimit = 300;
if (SPSecurity.AuthenticationMode != System.Web.Configuration.AuthenticationMode.Windows)
fts.AuthenticationType = QueryAuthenticationType.PluggableAuthenticatedQuery;
else
fts.AuthenticationType = QueryAuthenticationType.NtAuthenticatedQuery;
ResultTableCollection rtc = fts.Execute();
if (rtc.Count > 0)
{
using (
ResultTable relevantResults =
rtc[ResultType.RelevantResults])
retResults.Load(relevantResults, LoadOption.OverwriteChanges);
foreach (DataRow row in retResults.Rows)
{
if (!row["Path"].ToString().EndsWith(".aspx"))
//if (row["ContentType"].ToString() == "Item")
{
using (
SPSite lookupSite =
new SPSite(row["Path"].ToString()))
{
using (SPWeb web = lookupSite.OpenWeb())
{
SPFile file = web.GetFile(row["Path"].ToString());
items.Add(file.Item);
}
}
}
}
}
} //using ends here
});
return items;

Web Forms :: How To Interact Between Windows Media Player And Windows Media Services

Jan 12, 2011

I have an ASP .NET 2.0 (4.0 is an option) page that I've embedded the Windows Media Player to using OBJECT tags.

The player is connecting to a Windows Media Services publishing point on the Web server. This is on a 2008 server.

Everything works great, see it here: [URL]

If I understand correctly, the information the player is showing in its status bar comes from the ID3 tags of the current track. Continuing on this line of thought, the ID3 information must be coming to the player from the media server. Correct?

What I want to do is collect and use the information about the track that's current being played. I'd like to be able to create a custom display for the current track information. I'd also like to put a custom value in the track information to look up additional information about the artist/track from a database.
