I have an access DB created in 2007 and saved in 2003 (.mdb). The tables contain links to a file server on my internal network. I'm trying to import the db into Expression Web 4 and keep the links intact. Currently, I can get the import to work, but the links get stripped out and displayed as plain text.

View 4 RepliesI want to read some information from an xml file and store it ready in memory so that it can go out with every page response without being reloaded from the xml on every request.
What is the best way of doing this?
It looks to me like there are 2 options. Either create a class with static fields that the information is stored in. Or create a class with public fields that the info is stored in and create an instance of that class at application level.
Is that correct, are both of those options viable? or will I not be able to access the fields in the second method without creating an instance of the class in the code that responds to the page request(basically if you create an instance of a class at application level can you use that instance from within code anywhere in your website as long as it is public)?
Setting the .Net trust level to Medium on a site will ensure that no code can access files outside the application directory.
I have an ASP.Net site that must run in Full Trust. I have configured my website in IIS to use its own Application Pool Identity [URL].
Currently it is possible for scripts/code in this app to read files outside of the application directory. This occurs because by default, accounts that are a member of the BUILTINusers group are able to read most files on the system, including c: and c:windows. It appears that Applicaion Pool Identity accounts are also members of BUILTINusers.
Is it possible to prevent file access outside the website folder while keeping Full Trust?
I have a "search page" where the user enter some search criteria and a gridview where I display found records. When selecting "edit" on a row I open a second form to allow editing the found data. When the user click close button on the second form I want to go back to the search page. From the beginning I did just return (redirect to page 1) to the page but now the users also want to retain the search form with the serach criteria and found rows (also refreshing the found rows with possible changed data).
I can not just use a javascript with "history.back()" since the edit page might have done postbacks so that will not return to search page.Of course one solution would be to call the search page with a query string (or other ways to pass data between pages) containing the original search data but that solution might get messy.

View 1 RepliesI'm utterly new to APS.NET and in particular the MVC model...! I have a Telerik RadGrid control that I'm using. Until now (following NerdDinner) I was having the Model passed back to the view and this provided access to the various properties I wanted.
eg: Inherits="System.Web.Mvc.ViewPage<MySqlMvc.Helpers.PaginatedList<MySqlMvc.Models.Customer>>
.. lets me loop around the Model object and extract Customer data. This RadGrid control, however, needs me to use an EntityDataSource (hooked up via the designer). Does this have implications for maintaing the MVC pattern? I'm a little confused about how the EntityDataSource works in relation to my Model.EDIT: I do know there is an MVC version of the RadGrid but we also need the RadScheduler and a few others.. besides that, I'd still like to know the impact.
I need to keep my basket more permanent I have two options and I want to choose the best one.
I have eCommerce web site application in asp.net and there is a basket include products which are selected by users before, so options:
1- keep basket in database (consider the cost and time to store and retrieve information)
2- store my basket in Cookies (I don't know what the implementation is)
I couldn't use session because it is not permanent and clear by closing browser.
My goal is : when the user close the IE for 1 day or 2 days make ability to remember all products that already added to basket.
In addition, my basket is store in hash-table now, for example : {1:4055,2:4588,...} they are ID and product code(keys). they are all save in a hash table.

View 1 RepliesI am currently working on multiple group sites for the same parent company. All the sites are basically the same, and share the same code base however they have different stylesheets, master pages and config files.
As the number of sites is increasing I am finding it difficult to keep the sites synchronised and propagate bug fixes/changes across them all as each has it's own copy of the code.
Does anyone know of a way I could keep a single master copy of the site and easily propogate changes to each of the other sites.
I was wondering wich's the best way to "keep alive" the InputStream of the FileUpload Control.I would give you one example. Let's assume you have the FileUpload control in one WebForm, and you want process it in the next WebForm (after Response.Redirect).It would be great (unless for the memory) to have something similar to:
Session["PostedFile"] = this.FileUpload.PostedFile.InputStream.
Unfortunately, this results in:
System.ObjectDisposedException

View 1 RepliesI am having problems getting my head around this, so my terminalogy might be off. What I am trying to do is have a dropdown list with different groups, and then two listboxes that run queries based on the selection from the dropdownbox. The left listbox shows all items except those which are in the selected group. The right listbox shows only those in the selected group. I also have two buttons - one to move selected items from the left listbox to the right listbox, and another to move items from the right to the left.
My page has a dropdown list for Groups, populated with 2 records - Group A & Group B. Autopostback is set. When I change my selection on the dropdown list, my two listboxes do change
The problem comes in when I select items in the listbox and click on the transfer button. The records do transfer correctly (that is to say the database query executed correctly and data is moved), but the List boxes are not updated. What I want is to have the form refresh, but there is no AutoPostback for the Button object.
I tried inserting a Response.Redirect back to the same page at the end of the button click event. I thought this would allow me to process the sql command, and then refresh the data. This almost works. It does refresh the listboxes, but it also resets the dropdownbox to the first entry. This in turn changes what is displayed in the listboxes. The data is moved correctly though.
So at this point I have my choice. If the dropdown box behaves and does not change, then the listboxes don't update. If the listboxes do update, the dropdown box resets to the default value.
Example:-
column values:- Microsoft Java
I like to update above record using below SQL, so that new values are appended to old values instead of removing old values.
[Code]....
Output:- Microsoft Java some text
I have an ASP.NET project which is a front-end to a database. In addition to the large tables, the DB contains a few small tables to normalize the larger tables with common values. I have a VB.NET project which loads the smaller tables into memory, using "Shared" (i.e., "static" in C#) member variables, and uses them. I have a call to load the tables in Global.asax - Application_Start. This works for a while. That is, Application_Start runs when I first run my project, loads the cached values, and will correctly keep them in memory for a while.
What I'm seeing (when running my project via Visual Studio 2008 Debugger, hosted locally) is:
A) The Application_Start code will run more than once. Not in a row, but after the user has navigated to some other pages, I'll see (my breakpoint in) another call to initialize the cache, coming form Application_Start. Is it expected?
B) The "Shared" variable that was set to True when the cache was initialized is now False again (which should only happen when the class is first loaded). Similarly, all the data that was chached is no longer present. That is, it looks like VB is unloading all the Shared members. Is this expected?
If these are the expected behaviors, is there a way to do what I want? The code is in a module that is also used by other (non-ASP.NET) projects, and seems to work correctly for them. I'd rather not have to duplicate this functionality for something specific to ASP.NET, but would like to know what my options are.
I have a cascadingdropdown which works fine using a webservice and is populated. I can save the value of this dropdown to the database buy clicking a save button. However when the page reloads, the list is populated again. Is there a way to keep/set the selectedvalue after postback?

I'm developing a web app for which the client wants us to query their data as little as possible. The data will be coming from a Microsoft CRM instance.
So we've agreed that data will only be queried as and when it is needed, therefore if a web user wants to see a list of contacts (for example) that list is fetched into a local DataTable. Then if a new contact is created on the website the new contact is sent to CRM and added to the local DataTable at the same time. Likewise for edits.
If the user then looks at their contacts again the data will just come from the local DataTable.
I've many input elements one of which is, a radio button group with Autopostback set to true. After selecting one item from the radio button, the drop down list below fetches values from database and is refreshed. I choose some value in the dropdown list and submit the form. I've many server side validation controls. When I submit the form, if any of the server validation fails, it'll show the error message in the form. But the value I choose in the dropdown list disappears and it shows the first value of the dropdown list.
How to show the selected value in the list after submission of form?
Below is the partial code from my form. When I type anything other than "Hello" is the "Comments" text box, it will show the error message. I know I can use, other validators to check this. But purposely I want to use Customvalidator.

The Register action gets called in the Account controller, showing the RegisterViewModel in the Register.aspx view. The form in Register.aspx is submitted/posted with answers to all of the form questions, except for the security question answers. If the user is created successfully, then I'd like to go to the GoToSecurityQuestions view using the code - return RedirectToAction("GoToSecurityQuestions", "Account"); I need to be able to keep track of the user name or ID of the newly created user so that I can persist the security questions to the database records related to the user.

What is the best approach for keeping a user's search criteria saved in case they navigate back to the search page in MVC 2?
I was thinking of ViewData or creating a model that would keep that type of data.
I gather customer information on a asp.net page (.net 2.0) then I want to open a new page / window which will be passed all the payment details and then connect to our payment service provide to process the payment. Once done the payment window is then close and the original calling window is updated with the result of the payment.
I can do all of the above, except I don't know how to go about opening a 2nd IE window leaving the calling windows on the screen whilst passing parameters and retrieving the result.
My best guess would be:-
Stuff all the parameters into session state var's
Open a new windows / page pickup the session state var's
Process the details
Write the results back to session state var's
Close the new window
Pickup the results from the session stae var's
