JQuery Hotspots With Vb - Display Information On Hazard?
Jan 29, 2010
What I have is an image of a room (birds eye view) and in this image there are 4 red squares that each represent a hazard in the room for example a gas cylendar or a wind panel. What i want it to do is when the user highlights the red square is to get a text box appear to the right of the page and display the relevant data from the database regarding that particular hazard. So far with hotspots i have just managed to do a postback function and this is not enough. In my database i have a rooms table with a list of rooms e.g room1 room2 and room3 and i have a hazards table e.g gas cylendar, chemicals etc. Each room has up to 4 hazards and the image for the room is a simple blue rectangle with red squares around it. How do i exactly make it so that when a user hovers over the red part of the image it looks in the database at the room and see the hazards for that room then display the infomation on that hazard in a text box to appear?
i'm using vb web developer 2008. i'm trying to pull out data and display using the imagemap/hotspots. for example, when i search for this item 1, it will pull out the data from the database and then shows me where the item is placed on the map.
I want to develop a message bar in jquery which fetches information from server side asp.net code.I know how to connect jquery to call asmx service.I just want to know that, I will be using function from jquery to call asmx service. But to check for latest message on server, i need to call that function at regular interval like timer event. So how can i call jquery function to run at a particular interval to display messages from server?
Suppose I have an url like [URL} I can retrieve the 'form' value in code behind like Request["from"].How can I do the same using Javascript?Can I do this using Jquery also?If yes how can I do this?
A little stuck on this one:jQuery ajax message sent to the ASP.NET page with calls a WebMethod. The WebMethod creates an Zipper object that zips up a folder specified in the ajax message. I want to be able to pass data back to the client as to the progress of the zipping.I have this data in the Zipper object but I don't know how to pass it back.
This is a newbie question, and yes I have searched the web and the Help section. How do I display non-Bound information on the forms? Perhaps I should explain a little better.I have a form where I use dropdowns and other items to insert and update fields. These fields work correctly.
I haveasp:GridView displaying client requests using asp:SqlDataSource. I want to limit displayed information by client:
View.aspx has to display everything, View.aspx?client=1 has to display only requests from client ID #1.
So I'm using <asp:QueryStringParameter Name="client" QueryStringField="client" /> for query "EXEC getRequests @client". Everything works properly when some client is specified. But don't - if not. I tested my SP using SSMS - it works properly in both cases - when parameter is specified and when it isn't (NULL passed explicitly).
I was wondering if a user logs in using the login controller for asp.net, how do I display the users information in a "My Account" page. Do I simply do that through C# and SQL? Is there something that gets stored when a user logins already so I can return the username anywhere in the project?
I was looking at using the Jquery request to call a second aspx page which either inserts or selects records from the database. My concern is the security of using Ajax. To pass information to the second page the Ajax request constructs a query string which is read from the second page. However, I don't know if I feel comfortable having the query string parameters so easily accessible. Especially if inserting records using Ajax anyone could follow the page being pointed to and then just load that into a new window with the query strings filled in.This would result in potentially a database attack adding many fake rows.Are there any security measures I can put in place to keep my Ajax secure or preferably hidden?
I have a need to show sensative information but I would only like it available on screen for 2 minutes, and then after it dissapears.
Since this is part of my web application, I would like the user to stay logged into the web site before and after viewing the information, but in order to view it, I would like them to re-enter their username/password.
Are there any directions I can be pointed into accomplish this task?
I have a site I'm working on where the values being stored in user profiles can change so I need to iterate through all available profile options and display them (say in a label or gridview for instance). Here is an example of a web.config I threw together
In my code I am using a popup window to display extra information. I also have the ability to export the information in the main window to Excel.The problem is, after the window pops up -> I see the info -> I close the popup window -> but if I try the export to Excel button, it throws the exception "null object referrence" (if I use a try/catch, the exception doesn't occur - but I don't get any information). In the export function I am doing something like this:
{ //some code .... here con.close(); session["dss"] = mydataset; }
In the export button click event:
system.data.dataset dss = (system.data.dataset)session["dss"]; //then some work on this
I think, probably when the popup window opens it ends the execution and that's why when I come back to the main window and try the export button the values for the tables and all goes out of scope.Also, if I refresh the main page after closing the popup window I don't have any issue and can export the data.
I have a need to display user-specific information in my master page. As a result, I have set up all of my controllers to be inherited from a "master" controller. This has worked well for other aspects of the master page, such as displaying random quotes. However, while using this technique to incorporate the user-specific information, I ran into a problem where, when I check the Request.IsAuthenticated value, the Request object is null.
Here is my "master" controller:
[Code]....
Curiously - at least to me - is that the Request object becomes populated by the time program flow hits the Home Controller: [Code]....
Each of my ASP.NET pages currently has VB.NET code to change the text and display properties of a Label control, to display a message if an error occurs when any of the functions or routines fail. However, ideally it would be useful to have a generic error message popup displayed, with the option of inputting text via an argument.
If the site were in VB6, I'd be using the MsgBox function, since you can adjust the text displayed and change the type of message displayed (i.e. vbExclamation). The MsgBox can be called with minimal coding. But web pages will not support Windows.Forms
So another method here might be to use the ModalPopupExtender to display an error message using a Panel control if an error occurs, and to adjust the message content and icon depending on the type of error. But the problem here is that a Panel will need to be defined in each and every aspx page.
Ideally I want a public function (with an input argument or two) that will display a single Panel via a ModalPopupExtender, that can be called from any of my pages. The text and icons could be altered by the arguement values supplied.
how can I retrieve information when the user clicked on a specific link without opening a new web page? The information is stored in the database which is through web service. For example, when the user click on a specific link, e.g the date 28 February 2010, the datagrid will display the information on 28 February 2010.
I have been searching all over for this and trying many different things but so far have had no luck. I need to display the profile information for [all] users in the system within a GridView. For instance, I want to show their Username, First Name, Last Name,Email, etc.I've tried the Profilemanager.GetAllProfiles() method but t doesn't seem to have the fields in it.
the current page code below lists profile information of all users within with my site. i'd like to modify it so that it only displays information about the current user logged in.
I want to display client system information like username,ipaddress. I get only the remote address.Let me know how to get the client system information.
really new to the programming scene. writing a program so when i select an item from a drop down list i click the submit button and i want it to display the items selected from the database in a gridview. so in short i want to select an item click submit and i want it to display the information from the database.
