  • ASP.NET 2.0 control is not shown up un VS 2010 toolbox

    - by user353653
    Hi, I have developed some ASP.NET controls in .NET 2.0 with VS 2008. Now, I upgraded my project to VS 2010 but did not change the target framework to .NET 4.0 yet. But, surprisingly, I found that, the toolbox is not showing the bitmaps for the control added to the toolbox in VS 2010. Moreover, when I dragged and dropped a control (.NET 2.0) from the toolbox to my Web Form, I see some junk xml code added to my web form. I dont know if I need to recompile the .NET 2.0 controls with VS 2010 ? or what should I do in order to make the controls compatible for both in VS 2008 and VS 2010 ? I found that, there is no problem with Windows Forms control, rather it is just with ASP.NET Controls.

  • C# - LINQ Including headache...

    - by ebb
    Case can have many Replies and one User, Replies can have one Case and one User, One User can have many Replies and many Cases. ObjectSet <= Case Object (IDbSet) ObjectSet.Include(x => x.User).Include(x => x.Replies).FirstOrDefault(x => x.Id == caseId); But the User Object for each Reply are not included? Only the User object for Case is Included? How would I include the User objects for the Replies too? Thanks in advance!

  • Function to register functions to be called if event invoked.

    - by zaidwaqi
    Hi, I have a Panel which contains 20 PictureBox controls. If a user clicks on any of the controls, I want a method within the Panel to be called. How do I do this? public class MyPanel : Panel { public MyPanel() { for(int i = 0; i < 20; i++) { Controls.Add(new PictureBox()); } } // DOESN'T WORK. // function to register functions to be called if the pictureboxes are clicked. public void RegisterFunction( <function pointer> func ) { foreach ( Control c in Controls ) { c.Click += new EventHandler( func ); } } } How do I implement RegisterFunction()? Also, if there are cool C# features that can make the code more elegant, please share. Thanks.

  • Is there an user-level accessible font table present in Linux?

    - by youngdood
    Hi again Stackoverflow! Since there is this: http://en.wikipedia.org/wiki/Code_page_437 For MSDOS, is there something similar for Linux systems? Is it possible to access that font data via userland program? I would actually just need an access to the actual bit patterns which define the font, and I would do the rendering myself. I'm fairly sure that something like this exists, but I haven't been able to find what exactly is it and how to access it. After all, e.g. text mode console font has to reside somewhere, and I really do hope it is "rawly" accessible somehow for a userland program. Before I forget, I'm programming my program in C, and have access only to the "standard" linux/posix development headers. The only thing I could came up with myself is to use the fonts in /usr/share/fonts, but having to write my own implementations to extract the data from there doesn't sound really an option; I would really want to achieve this with the least amount of bytes possible, so I feel I'm left with finding a standard way of doing this. It's not really feasible for me to store my own 8x8 ASCII-compatible font with the program either(it takes some 1024 bytes(128 chars * 8x8 bits) just to store the font, which is definitely unacceptable for the strict size limits(some < 1024 bytes for code+data) which I am working with), so being able to use the font data stored at the system itself would greatly simplify my task.

  • How can I configure desktop notification display time in Google Chrome?

    - by netvope
    Recently Gmail introduced an HTML5-based desktop notification feature for Google Chrome users (see this). It's very useful, however, the notifications disappear too quickly (in about 5 seconds) and I couldn't find a way to change the display time. Ideally, I would like the notification to stay for a few minutes if there is no user activity (or about 15 seconds if there is user activity). Is that possible?

  • Knowing what input radio is selected on ASP.NET (VB)

    - by AZIRAR
    Hello, I'm creating input radio dynamicly on a ASP.NET page using PlacHolders. While reader.Read Dim ltr As New Literal() Dim ltr1 As New Literal() Dim ltr2 As New Literal() Dim ltr3 As New Literal() Dim ltr4 As New Literal() ltr.Text = reader.GetString(2) & "<br />" PlaceHolder2.Controls.Add(ltr) ltr1.Text = "<form> <input type = radio name=groupe" & i & " value=1>" & reader.GetString(3) & "<br />" PlaceHolder2.Controls.Add(ltr1) ltr2.Text = "<input type = radio name=groupe" & i & " value=1>" & reader.GetString(4) & "<br />" PlaceHolder2.Controls.Add(ltr2) ltr3.Text = "<input type = radio name=groupe" & i & " value=1>" & reader.GetString(5) & "<br />" PlaceHolder2.Controls.Add(ltr3) ltr4.Text = "<input type = radio name=groupe" & i & " value=1>" & reader.GetString(6) & "</form><br /><br />" PlaceHolder2.Controls.Add(ltr4) i = i + 1 End While My problem is : how can I get all the items selected on those input radio.

  • [Win32/MFC] Making group-boxes contain things

    - by John
    As I understand it, a group-box is just another control. Controls inside it are not owned by it, so unlike in Winforms, if you move a group-box the contained controls stay put. What would be the nicest way to address this? Just create your own data-structure mapping controls to 'container' group-boxes so that when the container is moved the children are automatically moved?

  • int i vs int index etc. Which one is better?

    - by Earlz
    Coming from a C background I've always used int i for generic loop variables. Of course in big nested loops or other complex things I may use a descriptive name but which one had you rather see? int i; for(i=0;i<Controls.Count;i++){ DoStuff(Controls[i]); } or int index; for(index=0;index<Controls.Count;index++){ DoStuff(Controls[index]); } In the current project I am working on there are both of these styles and index being replaced by ndx. Which one is better? Is the i variable too generic? Also what about the other C style names? i, j, k Should all of these be replaced by actual descriptive variables?

  • Need help with tweaking a Dropdown with three options, user selects one - a hidden div appears with correct fields

    - by Jack
    Hello Again, I posted a question on here and got an answer within minutes I'm hoping the wizards on here can help me again. Okay so I'm using a script I found online to try and add this function to a shopping cart form. Here's the setup. I have a payment method dropdown with Visa, Mastercard and Bank Withdrawal as the options. For the credit cards I have one hidden div with a certain set of fields, and for the bank I have another hidden div. Each of the divs have named ID's - #payCredit and #payBank The css for both have margin: 0px and display: none; Here's a peice of javascript I used successfuly on a shipping address checkbox `function toggleLayer( whichLayer ) { var elem, vis; if( document.getElementById ) // this is the way the standards work elem = document.getElementById( whichLayer ); else if( document.all ) // this is the way old msie versions work elem = document.all[whichLayer]; else if( document.layers ) // this is the way nn4 works elem = document.layers[whichLayer]; vis = elem.style; // if the style.display value is blank we try to figure it out here if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined) vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none'; vis.display = (vis.display==''||vis.display=='block')?'none':'block'; }` I was hoping I could change it slightly to meet my needs. Here's the dropdown <label>Payment Method:</label> <select name="payment" id="payment" class="dropdown3" style="width:8em"> <option selected="selected">Select</option> <option value="Visa" onclick="javascript:toggleLayer('payCredit');">Visa</option> <option value="MasterCard" onclick="javascript:toggleLayer('payCredit');">Mastercard</option> <option value="Direct" onclick="javascript:toggleLayer('payBank');">Direct Withdraw</option> </select></li> The current result is that it kinda works. I can open the dropdown and select Visa and it appears, if I select Visa again it disappears, if I select Visa and then select bank, both appear. You can see what i'm working on here - http://test.sharevetcare.com/bestfriends/cart3.html

  • Silverlight "Out of browser application" vs. "Install from page"

    - by Matt McMinn
    I’ve been working on integrating some controls which call in to COM classes in to a Silverlight client. Since my controls use COM, they only work out of browser. The client does have out of browser installation options turned on, and when I launch the client from visual studio, I can right click it, and install it to the desktop. That all seems to be working fine. The strange part though is that my controls don’t work when they’re out of browser – I get an error that the COM server can’t be started. The stranger part is that if I go in to the clientproperties, and set the Start Action from “Dynamically generate a test page” to “Out of browser application”, my controls work fine, and I get no COM errors. So I guess I don’t understand the difference between installing the application to the desktop through the right click menu and setting the application to start as an out of browser application. Any idea what's going on here?

  • How to show specific link to user that's signed in and on specific page in rails?

    - by sevens
    I have the following code for part of my navigation: <% if user_signed_in? %> <li><%= link_to 'Edit Profile', edit_profile_path(current_user.profile) %></li> <li><%= link_to 'Edit Account', edit_user_registration_path %></li> <% elsif user_signed_in? and params[:controller] == 'profiles#edit' %> <li><%= link_to 'View Profile', profile_path(current_user.profile) %></li> <li><%= link_to 'Edit Account', edit_user_registration_path %></li> <% else %> <li><%= link_to 'Sign up', new_user_registration_path %></li> <% end %> I want different links to show depending on where the "user_signed_in" is. However, my <% elsif user_signed_in? and params[:controller] == 'profiles#edit' %> doesn't seem to be working. What am I doing wrong?

  • How does Ocaml decide precedence for user-defined operators?

    - by forefinger
    I want nice operators for complex arithmetic to make my code more readable. Ocaml has a Complex module, so I just want to add operators that call those functions. The most intuitive way for me is to make a new complex operator from all of the usual operators by appending '&' to the operator symbol. Thus +& and *& will be complex addition and multiplication. I would also like ~& to be complex conjugation. If I'm going to use these operators, I want them to associate the same way that normal arithmetic associates. Based on the following sessions, they are automatically behaving the way I want, but I would like to understand why, so that I don't get horrible bugs when I introduce more operators. My current guess is that their precedence is done by lexically sorting the operator symbols according to an ordering that is consistent with normal arithmetic precedence. But I cannot confirm this. Session one: # open Complex;; # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} Session two: # open Complex;; # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} # let (~&) a = conj a;; val ( ~& ) : Complex.t -> Complex.t = <fun> # (one +& i) *& ~& (one +& i);; - : Complex.t = {re = 2.; im = 0.}

  • node.js: looping, email each matching row from query but it it emails the same user by # number of matches?

    - by udonsoup16
    I have a node.js email server that works fine however I noticed a problem. If the query string found 4 rows, it would send four emails but only to the first result instead of to each found email address. var querystring1 = 'SELECT `date_created`,`first_name`,`last_name`,`email` FROM `users` WHERE TIMESTAMPDIFF(SECOND,date_created, NOW()) <=298 AND `email`!="" LIMIT 0,5'; connection.query(querystring1, function (err, row) { if (err) throw err; for (var i in row) { // Email content; change text to html to have html emails. row[i].column name will pull relevant database info var sendit = { to: row[i].email, from: '******@******', subject: 'Hi ' + row[i].first_name + ', Thanks for joining ******!', html: {path:__dirname + '/templates/welcome.html'} }; // Send emails transporter.sendMail(sendit,function(error,response){ if (error) { console.log(error); }else{ console.log("Message sent1: " + row[i].first_name);} transporter.close();} ) }}); .... How do I have it loop through each found row and send a custom email using row data individual row data?

  • Can an Oracle user get a list of its own running sessions without access to v$session?

    - by Nick Pierpoint
    I have an application that runs a process and I only want one process to run at a time. Some options are: Use an object lock to prevent subsequent processes running. This would be fine, but I want the calling session to return immediately and not wait for the running session to complete. Use a custom Y/N to set whether a process is running or not. I set a "Y" flag at the start of the process and set it to "N" when it finishes or fails. Also fine but feels like I'm re-inventing the wheel and doesn't feel like the way to go. It also falls short if the running session is killed as the flag stays at "Y". Use dbms_application_info.set_module This approach seems the most robust, but if I'm to know there's an existing running process I think I need to be able to query v$session and I don't want this application to have such wide access. Any ideas?

  • InvalidCastException: System.Web.UI.PartialCachingControl -> MyCustomControl when OutputCaching

    - by marcinn
    The problem: I am unable to use OutputCaching with my controls which derives from MyCustomControl. Controls are loaded dynamically using definitions from database with Page.LoadControl method. When I add to ascx <%@ OutputCache VaryByParam="*" Duration="3600"% the "InvalidCastException: System.Web.UI.PartialCachingControl - MyCustomControl" exception is thrown. I am unable to modify assembly witch contains dynamic loading controls logic. Is there any way to fix it in derived controls? The second question is about iis7 and native output caching - is it resolves this problem? (I tried to set up several performance counters and I saw that cache wasn't hit...)

  • Delete Entity in Many to Many Relation. Don't get error but entity is not deleted

    - by Shapper
    I have, in EF5, two entities: User and Role. Between User and Role there is a many to many relation. I don't have an entity for the UserRoles database which sets the relation. I have a User and I want to delete a role without loading it from the database. Context context = new Context(); User user = context.Users.First(x => x.Id == 4); user.Roles = new List<Role>(); Role role = new Role { Id = 20 }; context.Roles.Attach(role); user.Roles.Remove(role); context.SaveChanges(); I don't get any error but the role is not removed. Any idea why? Thank you, Miguel

  • How to check of which user-defined type a current JSON element is during $.each()?

    - by Bob
    I have the following structure for a JSON file: ({condos:[{Address:'123 Fake St.', Lat:'56.645654', Lng:'23.534546'},{... another condo ...},{...}],houses:[{Address:'1 Main Ave.', Lat:'34.765766', Lng:'27.8786674'},{... another house ...}, {...}]}) So, I have a list of condos and houses in one big JSON array. I want to plot them all on my map, but I want to give condos and houses different marker icons( blue marker for condos, green marker for houses ). Problem I have is - figuring out how to distinguish between types of markers when I $.each() through them. How would I use if to check whether I'm working with a condo or a house at the moment? var markers = null; $('#map').gmap(mapOptions).bind('init', function(){ $.post('getMarkers.php', function(json){ markers = json; $.each(markers, function(type, dataMembers) { $.each(dataMembers, function(i, j){ //if house use house.png to create marker $('#map').gmap('addMarker', { 'position': new google.maps.LatLng(parseFloat(Lat), parseFloat(Lng)), 'bounds':true, 'icon':'house.png' } ); //if condo use condo.png $('#map').gmap('addMarker', { 'position': new google.maps.LatLng(parseFloat(Lat), parseFloat(Lng)), 'bounds':true, 'icon':'condo.png' } ); }); }); }); });
