I have a Main program form which launches a new Login form. I would like my application to require user to log in before he can manipulate with the Main form.
I create the Login form from code as a new LoginForm class. User can simply click on the Main form. So i would like to deny access to main form until the user loggs in.
a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
I have a class bMainframe that manages the connections to 4 different mainframes. It allows for the same underlying unmanaged library to be opened in specific ways and more than one mainframe to be connected to at a time. Each library has its own disposal code for the unmanaged mainframe connection resource. The wrapper also has code that calls the individual mainframe connection's disposal code.
This causes an error if someone's project does not make use of all 4 mainframes, but calls the disposal on the wrapper. (FileLoadException could not load assembly X of the 4 managed mainframes) Since that disposal code checks to see which of the 4 are not nothing/null. Even if nothing/null this is causing .net to try to load the assembly and crash.
Is the disposal code in the outer wrapper helpful or necessary? is there a way to check if the assembly for a type is even loaded that doesn't trigger.net to load the type/assembly?I modified the code below to block the fileloadexception, but I don't believe this is the best way.

I have to use Form.Action to redirect to a script that will be picking up values from my page. It is worth noting that this script is external.My issue is that I also want the button that is clicked and has the Action hooked up to it, to also complete some functionality in the code behind first.Is there anyway I can either :In the buttons click event handler, can I set the Form.Action and then call something such as Form.Submit?OR Set up the Form.Action in advance and then somehow have the button posting back before the action takes place.
View 5 RepliesWhat i want is i have a listbox in form a, which display data from database, for example it's displaying student ID.
after user double click on the id, form b will "show" and load that particular informations.so should i do that action in ListBox1_DoubleClick or form b_load?
I have just updated my ASP.NET application from .NET 3.5 to 4.0. One of the breaking changes is the form action attribute is empty when navigating to the root folder, instead of previously automatically picking up default.aspx.
Seting the action attribute in markup or in the code-behind doesn't work as the action attribute is still empty when the page is rendered.[code]....

this is my first time making an application so I would like to make a Login form in VB. I haven't gotten into any problems so far but my question to you are the following1) Is it possible for me to make an event/action that will allow it to work with the script that is php? IE: Application has a button that will scan all files in /public_html for viruses, when the button is clicked, it will send the event to cPanel and make it scan all files.2) Once the user has connected and all information has been verified make another window show and the new application will be the new window.Another question I have isRight now I'm using WHMCS(url..) for my billing system they have an intergtation code that I use for my web page and it goes like this

View 4 RepliesI have made a login system for secure file storage. The way it works, is when you create an account it adds values to the registry containing the password and username. It needs to have administrator privileges to write those values, but not to read them. It would be very inconvenient to have to run as an admin every time, so I need to know how to require administrator privileges when the click the "Create Account" button, but not require admin rights when the program starts up.

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.
I know there are several ways to publish updates but I would like to know the best way to do it. What I already have configured is a shard network folder which I intend to have the program update from there. What would the best way to publish updates to the folder be?
View 1 RepliesIf my if is not correct, and it goes in the 'then', how is it possible to redo my whole sub? I want to automate a whole sub.
View 1 RepliesI have searched high and low for documentation on how to use this feature. While the loop I could write would be simple and take no time, I really would like to learn how to use this. Basically I have a class, say, Widget, with a Save() sub that returns nothing. So:
Dim w as New Widget()
w.Save()
basically saves the widget. Now let's say I have a generic collection List(Of Widget) name widgetList(Of Widget) and I want to run a Save() on each item in that list. It says I can do a
widgetList.ForEach([enter Action(Of T) here])
....but how in the F does this work??? There is no documentation anywhere on the intrablags.
I am having trouble doing something that is probably pretty simple!I have a stock listing that is done by 1) a simple form with parameters (Index) and 2) an ajax called partial view that displays the list of stock (based on the params).On this same simple form (Index) I have an action link to an "Add Stock" method which calls another form for adding stock.When the user has finished adding the stock I redirect them back to the stock list page (Index).
My issue is that I would like to "remember" the parameters that were initially entered in this form so the user isn't just directed back to a page with blank parameters forcing them to enter them again.I thought I could simply overload the Index method as such:
[Code]...
I get this error: The current request for action 'Index' on controller type 'StockController' is ambiguous between the following action methods:.Now I have read this post and it's answer but I cannot figure out how to implement the solution. Is this solution applicable in my situation? Is there a better way to acheive what I'm trying to do?
