  • Splitting a string in ASP Classic

    - by Sam
    So here's my string: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam elit lacus, dignissim quis laoreet non, cursus id eros. Etiam lacinia tortor vel purus eleifend accumsan. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Quisque bibendum vestibulum nisl vitae volutpat. I need to split it every 100 characters (full words only) until all the characters are used up. So we'd end up with: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam elit lacus, dignissim quis laoreet non, and cursus id eros. Etiam lacinia tortor vel purus eleifend accumsan. Pellentesque habitant morbi tristique and senectus et netus et malesuada fames ac turpis egestas. Quisque bibendum vestibulum nisl vitae volutpat. Any ideas on the best way to do that?

  • Setting the ASP.NET version via MSBUILD

    - by dovholuk
    I am trying to create a new website on a remote server via msbuild (I like to call it "msdeploy"). I've downloaded and used the SDC tasks, the MSBuildExtension tasks and the MSBuildCommunity tasks but I simply can't get it right. I figure that WebDirectorySetting (from MSBuild.Community.Tasks.IIS) is my best bet but I can't find the right SettingName to pass. I'd like to use some sort of MSBuild task to accomplish this but maybe it just doesn't exist. Custom VBS or WMI are my last resort... Thanks

  • Searchfield with autocomplete ASP.NET and Database

    - by Fogh
    Searchfield with autocomplete I would like to make a searchfield with autocomplete, so when you write like 2 or 3 letters it will show a dropdownlist with results that match a column from a table in the database. I have been reading all over the internet, and i have found out that it can be done with jQuery and AJAX Control Toolkit. But i don't know how to make it compare the search textbox and the database and show results that match?

  • .net user control event handler lost on postback

    - by user154008
    I have a menu usercontrol called LeftMenu that has a bulletedlist of linkitems. It's on the ascx page as such: <asp:BulletedList ID="PublisherList" DisplayMode="LinkButton" OnClick="PublisherList_Click" cssClass="Menu" runat="server"></asp:BulletedList> I databind the list in the page_load under if(!isPostBack) I'm having an issue on a page that loads the control. When the page first loads, the event handler fires. However, when the page posts back it no longer fires and in IE8, when I'm debugging, I get "Microsoft JScript runtime error: Object expected" in Visual Studio pointing at "doPostBack('LeftMenu$PublisherList','0')." In FF I don't get the error, but nothing happens. I'm **not loading the control dynamically, it's loaded on the aspx page using: <%@ Register TagPrefix="Standards" TagName="LeftMenu" Src="LeftMenu.ascx" %> <Standards:LeftMenu ID="LeftMenu" runat="server"/> Any ideas of where I'm losing the event handler? I just realized this is happening on another user control I have as well. A text box and a button and I'm using the default button to make sure pressing the enter key uses that button. .Net converts that in the html to: <div id="SearchBarInclude_SearchBar" onkeypress="javascript:return WebForm_FireDefaultButton(event, 'SearchBarInclude_QuickSearchButton')"> so as soon as i enter a key in the box I get a javascript error at the line saying "object expected." It seems like the two issues are related. Edit Again: I think I need to clarify. It's not that I'm clicking on the menu item and it can't find the selected item on postback. I have this search page with the left navigation on it and then the main content of the page is something that causes a postback. Everything is fine with this postback. Once that page has been posted back, now if I click on the bulleted list in the left navigation I get a javascript error and it fails. The page_init for the LeftMenu control is never called.

  • Providing SaaS functionality to a .NET portal with DLLs

    - by Abdullah Jibaly
    I'm not sure I'm asking the right question here, but I'm looking to provide web based functionality from one ASP.NET application to another remote 'portal-like' application. Is it possible to simply give the portal a DLL? As an example, let's say the SaaS web app has a patient-entry form that I want to be able to use from the portal application. I would like the portal app to be able to set preferences (permissions, color, style, etc), make a function call, and have that capability presented within a certain div or something. Is there any .NET technologies that provide this kind of integration?

  • ASP.NET - fast Segmented downoad of file through webservice

    - by H4mm3rHead
    Hi, Im doing this project where i need to download files through a webservice (images, videos). The download MUST go through an existing webservice. The existing webservice was made when there were no need to upload and download files but the project has changed and now we need to do It through a webservice. Right now I have implemented the download as a method that returns a byte[], I open a streamreader and resds the entire file into a byte[] and returns it to my method. This is working file on small files <~1Mb, above it takes too long time. I want to show some progress (e.g. when the user downlaods a 20Mb video) which i cannot do right now. And i want to make it download much faster (is a strategy to use multithreading and several threads that downloads a part of the file?). It is within a WPF application i need to do this. Any ideas on how to approach this?

  • Hide Non-Displayed ASP Elements in Design View

    - by Steven
    Is there a way to prevent non-displayed elements from appearing in the ASPX Design View editor? By "non-displayed elements", I mean the background elements (Managers, DataSources, Validators, etc) that show up as grey boxes containing the type and id. If I have several of those at the top of the page, I can't see much of the preview of my page.

  • C# ASP.NET Binding Controls via Generic Method

    - by OverTech
    I have a few web applications that I maintain and I find myself very often writing the same block of code over and over again to bind a GridView to a data source. I'm trying to create a Generic method to handle data binding but I'm having trouble getting it to work with Repeaters and DataLists. Here is the Generic method I have so far: public void BindControl<T>(T control, SqlCommand sql) where T : System.Web.UI.WebControls.BaseDataBoundControl { cmd = sql; cn.Open(); SqlDataReader dr = cmd.ExecuteReader(); if (dr.HasRows) { control.DataSource = dr; control.DataBind(); } dr.Close(); cn.Close(); } That way I can just define my CommandText then make a call to "BindControls(myGridView, cmd)" instead of retyping this same basic block of code every time I need to bind a grid. The problem is, this doesn't work with Repeaters or DataLists. Each of these controls inherit their respective "DataSource" and "DataBind" methods from different classes. Someone on another forum suggested that I implement an interface, but I'm not sure how to make that work either. The GridView, Datalist and Repeater get their respective "DataBind" methods from BaseDataBoundControl, BaseDataList, and Repeater classes. How would I go about creating a single interface to tie them all together? Or am I better off just using 3 overloads for this method? Dave

  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

  • Windows SQL wildcards and ASP.net parameters

    - by Vinzcent
    Hey In my SQL statement I use wildcards. But when I try to select something, it never select something. While when I execute the querry in Microsoft SQL Studio, it works fine. What am I doing wrong? Click handler protected void btnTitelAuteur_Click(object sender, EventArgs e) { cvalTitelAuteur.Enabled = true; cvalTitelAuteur.Validate(); if (Page.IsValid) { objdsSelectedBooks.SelectMethod = "getBooksByTitleAuthor"; objdsSelectedBooks.SelectParameters.Clear(); objdsSelectedBooks.SelectParameters.Add(new Parameter("title", DbType.String)); objdsSelectedBooks.SelectParameters.Add(new Parameter("author", DbType.String)); objdsSelectedBooks.Select(); gvSelectedBooks.DataBind(); pnlZoeken.Visible = false; pnlKiezen.Visible = true; } } In my Data Acces Layer public static DataTable getBooksByTitleAuthor(string title, string author) { string sql = "SELECT 'AUTHOR' = tblAuthors.FIRSTNAME + ' ' + tblAuthors.LASTNAME, tblBooks.*, tblGenres.GENRE " + "FROM tblAuthors INNER JOIN tblBooks ON tblAuthors.AUTHOR_ID = tblBooks.AUTHOR_ID INNER JOIN tblGenres ON tblBooks.GENRE_ID = tblGenres.GENRE_ID " +"WHERE (tblBooks.TITLE LIKE '%@title%');"; SqlDataAdapter da = new SqlDataAdapter(sql, GetConnectionString()); da.SelectCommand.Parameters.Add("@title", SqlDbType.Text); da.SelectCommand.Parameters["@title"].Value = title; DataSet ds = new DataSet(); da.Fill(ds, "Books"); return ds.Tables["Books"]; } Thanks, Vincent

  • asp.net webservice user management across pages

    - by nakori
    I'm developing a site that will display confidential readonly information, with data fetched from a WCF service. My question: What is the best approach to user management across different information pages. The service returns a collection with customer info after a secure login. My idea is to have a Customer object class that is stored in session. Is it possible to use things like HttpContext.Current.User.Identity.IsAuthenticated followed by HttpContext.Current.Session["UserId"] without using a database with role-based security? Would I be better off with a combination of local database, Linq to SQL or datasets rather than using just class objects for data fetched from service? thanks, nakori

  • Resizing Images with ASP.NET and saving to Database

    - by Ryan
    I need to take an uploaded image, resize it, and save it to the database. Simple enough, except I don't have access to save any temp files to the server. I'm taking the image, resizing it as a Bitmap, and need to save it to a database field as the original image type (JPG for example). How can I get the FileBytes() like this, so I can save it to the database? Before I was using ImageUpload.FileBytes() but now that I'm resizing I'm dealing with Images and Bitmaps instead of FileUploads and can't seem find anything that will give me the bytes. Thanks!

  • Core dump utility for .NET

    - by Dave
    In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

  • ASP.net SessionState Error in Design Mode

    - by stringo0
    I'm getting a weird error in the design view for a user creation page for 2 controls: Error Creating Control - wCreateUser Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. (There's some more) I've done both of these, but I'm still getting the error in design mode. The controls work fine when compiled, and on the live site - this is just in the Visual Web Developer 2010 Design view for the page. Any ideas as to how I can resolve this? Thanks!

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • ASP.NET handling button click event before OnPreInit

    - by Phillykins
    Hello, I have a data access layer, a business logic layer and a presentation layer (ie. the pages themselves). I handle the OnPreInit event and populate collections required for the page. All the data comes from an SQL server database and I do not use caching. I handle a button click event to grab values from a form and insert a new object into the database. The problem is that by the time I handle the click event, the collections have already been populated, so the new item which has been inserted into the database has not been retrieved. What is the accepted solution to this? I could insert the new object directly into the collection and re-bind the GridView, but the SQL query selects only a set of objects and the new object could fall outside of this set. Thanks!
