Am using asp.net 2.0 .i am having a windows control library.dll in my webform ,but it is not loading correctly.i have attached the code below.
<form
id="form1"
runat="server">
<object
classid="http:controllibrary.dll#controllibrary.UserControl1"
id=
"myid"
height="450"
width="800"
VIEWASTEXT>
</object>
</form>
It has a part where it sends new users their first password in email.. and yes I'm getting that annoying cannot access CDO.Message object error traced back to the "Error loading type library/DLL" message. but I remember that it used to work fine with my old computer I started the development on.
1. It isn't a permission error.. like most cases (tried granting admin access to the ASPNET user)
2. I have the required dll files registered (checked them several times and even reinstalled them a few times)
3. Tried putting only that piece of code in a new application to be able to experiment.. Started commenting out blocks of code until it finally "worked" (I didn't get the error). So it seems like I only get the error if I add a mail field (which is bad since I need those for authentication..)
We have installed a web site written by others which is compiled with Visual Studio 2008 and hosted in Windows server 2008 R2.
The IIS connection timeout is set to 120 seconds. But for some pages, the first page loading fails with HTTP 404 error but sequential refresh can bring the page up. The same problem happens for some images which fail to load in web pages. We are not very sure it is network related issue or hosting issue.
I create a windows forms control library project, And build it. then i want it's dll to my web project, for this i used object tag which can display it on page. I made reference of dll to my project.did the following coding.
<object id="conlib1" classid="clsid:{2483F435-673D-4FA3-8ADD-B51442F65349}"
codebase="Default.aspx" >
<param name="F:sandyWindowWincontrolLibWincontrolLibinDebugWincontrolLib.dll" value="WincontrolLib.dll" />
</object>
although page is asking to install but after that my control should be displayed but nothing is to be shown there.
I have a Web project in which I defined some methods to parse some webpages. I then save the retrieved data in a DB. Now I have run a lengthy operation(it may take 2 days) in which I continously parse webpage this way.
Can I use the webproject from a Windows project. If I try to add a refference to it it doesn't work. How should I do it? I have used until now an asp.net application, and done the calls to the parsing methods in the pageLoad event but after an hour or so the process stops.
I just changed my NHibernate application to use the Unit of Work pattern. I then continued through this tutorial to the part where it starts using HttpContext to determine whether or not the code is running in an web application. Using Visual Studio 2010 I get the error "The name 'HttpContext' does not exist in the current context". So I added a reference to System.Web and imported the namespace. The sample code then checks whether or not HttpContext.Current is null to determine whether this is a web or windows application. Is this the best way of doing that?
View 2 RepliesI have one C# windows class library type project which has a web reference whose settings are automatically added in to settings.settings file( Webservice name, type, scope, value).
I also have one separate ASP.net project which has let us as suppose, one page with a button. When I click this button, it calls a method of referred DLL of previous project and control goes there.
When in that project, when control goes in to location where I use this web reference, it tries to get the URL of web reference from settings file and raises an exception - 'The current configuration system does not support user-scoped settings'.
So, What is the way for me to call a c# project having web service in a asp.net project ? This is really a source stopper for our development.
I have a windows service that calls a class library. The call to the Class library from the windows form application works fine. But from the service I do get the desired output. The event viewer does not report any error. The service was working fine until the recently when the server got remastered. Any suggestions what might have gone wrong?

View 2 RepliesWe 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;
}
I have a custom DDL that lives in my Server control library. Currently I add this control to a table by strongly typing the name of the control, the customary way.
Control_Library.Report_NumberDDL newDDL = new Control_Library.Report_NumberDDL();
What I want to be able to do is dynamically create that control by pulling the control name from a table. So I would have the name of the control in my code, in this case "Report_NumberDDL", and I would like to then create the control without having to strongly type it.
Something like this, though I know this doesn't work:
string controlName = "Report_NumberDDL";
Control_Library."controlName" controlNum1 = new Control_Library."controlName"();
Edit:I tried to do this:
Type type = Type.GetType("Control_Library.Report_NumberDDL");
object control = Activator.CreateInstance(type);
But on the CreateInstance(type) I get a null value exception. So the Type isn't getting created correctly.
How would i go about loading a different control over an existing control?
By this i mean when i visit a page, a control is loaded into a PlaceHolder or Panel control, and then after i am finished with that UserControl, i want to clear it out and then load the next control in its place.
I have tried doing PlaceHolder.Controls.Clear but it still retains the first control and doesnt even add the next control to it at all.
The initial control is a data-entry control (Insert/Edit). Once the user does the data-entry (Insert for this question) needed, they click the Insert button, the data gets inserted into the database correctly then i want to pass control back to the parent page and have it load the next data-entry usercontrol in the place of the initial usercontrol.
I have tried doing it dynamically, with one placeholder control but that didnt seem to work. I tried doing it via a MultiView control with each of the data-entry usercontrols needed being pre-loaded into their own view and i couldnt get the Mutli-View to change activeindex.

I am using file upload control in aspx page. I want to put file upload logic in class library. but not getting how to distribute logic.
View 2 RepliesI have a control in a 'window control library' which handles - 'drag and drop' files from computer to a listbox control, I then reference this .dll in .aspx (See code below). Now, when i try to access this through webserver for drag
and drop files i get following errror - The type of the first permission that failed was : System.Security.Permission.FileIOPermission.
How do I handle this, so that drag and drop of files can happen over the webpage residing at webserver.

I have created an asp.net application which contains a user control. Within the application this control works fine. I have then moved the control into a separate "control library" project. When I try to load the control from the control library I find that the asp elements defined in the ascx for the control are not instantiated - i.e. I get a null reference exception in the Page_Load event handler. The only changes that I have made to the original application are to reference my control library and to change the <%@ Register statement in the loading page to reference the control library dll:

Do I need to do something else to get the user control to initialize itself correctly?

View 3 RepliesI am looking at the twitter api page http://apiwiki.twitter.com/ and I noticed that they have already built libraries that are wrappers against the twitter api. So I am thinking this is the best way to go but I am unsure which C# library I should use.
What I am trying to do is make some simple service or cmd line application that will help me automate retweeting.
So I am looking for a library that will allow me to get posts from other twitter accounts and then retweet them from another account.
I am not sure if the library can do this or not. Otherwise I was thinking of getting the RSS feed from the twiter account I want to get the twitters from parse out the new ones and use a library to retweet them on my own account.
I have not used twitter much so I am hopping someone can shed some light on this.

i need to load data into literal control which is coming from wcf service.
The data which i get is may be of a simple string are may be a html page in the form of string.
what ever the service returns the string i should load that into the literal control.

I have an Asp.net app that simply reads an xml file and this code used to work fine on Vista with VS2008, now I just moved to Windows 7 and I migrated the code to VS2010, I encoutered "Access to the path [path to my webapp folder] is denied". Nothing else is changed, I tried to change folder perms even though I didn't think it got anything to do with that since the same code used to work fine, but still didn't get around this problem. Could someone shed some light on why this may be happening and how to fix it?
