I'm trying to build a web application that uses an SSL connection. So I did some research and found out that I could use the RequireHttpsAttribute class to achieve what I needed. Thing is that when I use it, the execution of the application results in an 310 error(too many redirections). I even built a custom class to handle the switch from http to https. [code]

My job is requiring some visual basic programming and i've only programmed in C#.So i have this code:
Public Custom Event Command As JQDialogEventHandler
AddHandler(ByVal value As JQDialogEventHandler)
commandHandler += value[code].....
I'm getting the error: Operator '+' is not defined for types 'ControlesModificados. ControlesModificados.JQDialogEventHandler' and 'ControlesModificados. ControlesModificados.JQDialogEventHandler'. How can i write this code "commandHandler -= value" in other way so the error goes away! or how can i defined those operators for the eventhandler.
Namespace ControlesModificados
Public Class JQDialogButton

As you can see the DialogCommand is using another JQDialogHandler, so i can't just use
Public Custom Event DialogCommand As JQDialogEventHandler
I'm creating an ASP.NET Custom Control for my web application which is basically an ASP.NET Button control contained inside multiple <div> elements (for styling purposes).How can I create a Click event handler for my custom control so that my control acts as an ASP.NET Button?

Sub myButton_Click(sender as object, e as EventArgs) Handles myButton.Click

Dim o As New System.IO.DirectoryInfo(Application.StartupPath() + "p") Dim myfiles() As System.IO.FileInfo
myfiles = o.GetFiles("*.r**")i have such code. for example I got 4 files in tmp dir. it's called file.rar, file.r00, file.r01 and file.r02 ,the return Array always comes as follow file.r00, file.r01, file.r02 and last is file.rar. Now I want the result in order like first file.rar and next is 00 01 02 03...n etc how to make it ? anyway dont make .rar in last I want to make it in the first place.seems there is a Array.Sort but I dont know how to use it this way.
I've created a custom MessageBox (a Form), that has buttons Yes and No. There is a function popUp() to show the MessageBox. I would call the MsgBox in a parent as follows:
CustomMessageBox.popUp()
Now I want the message box to return a value:
Dim a as Intger = CustomMessageBox.popUp()
But this should only return once the user clicks a button in the message box.
My popup sub:
Dim thread As New Threading.Thread(AddressOf GetResult)
Public Function PopUp(Optional ByVal ErrorMessage As String = "", Optional ByVal Title As String = "", Optional ByVal ButtonType As ButtonType = ButtonType.OK, Optional ByVal MessageType As MessageType = MessageType.None)
[Code] .....
gotResult is a Boolean = false. It the user clicks a button gotResult is changed to true.
result is a integer containing the number of the button clicked.
When I run this code, the result is returned, even if the user doesn't click a button. I understand why, because the main thread of the form is not "paused" while the user has not clicked a button. How can I pause the message box itself, until a button was clicked?
I've tried this:
Public Function PopUp(Optional ByVal ErrorMessage As String = "", Optional ByVal Title As String = "", Optional ByVal ButtonType As ButtonType = ButtonType.OK, Optional ByVal MessageType As MessageType = MessageType.None)
[Code] .....
But now the whole message box is captured in a loop and the message box is like disabled, because it waits for the loop to end, so the user can't click anything.
I am developing a custom messagebox class like the following-[code]...

I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
With the MVC3 Razor synax, one may render a string like so
@ViewData("photo")
My problem is: How can I append a dot to the above code.The following will result in a "Public member 'jpg' on type 'String' not found.

I've tried the following code but does not produce my intended result:
@ViewData("photo") .jpg
@ViewData("photo"):.jpg
@ViewData("photo") & ".jpg"
I'm quite new to MVC and while I've been trying to follow the best practices , I believe I may not be understanding certain fundamentals of either
-a. Using models and viewmodels appropriately
-b. Passing models into a controller for validation purposes.
The general purpose of my program is to select a stored procedure from a list of stored procedures, create a form where the user can fill out all the appropriate input variables, and then to execute that stored procedure. The tool is for non-technical people, so I'm eventually going to have to do a good deal of input validation.
As such I have four models: A Script Model, a Parameter Model, a Parameter Enum model and a Query Model, and two viewmodels: a paramviewmodel that generates the form to fill out, and a scriptviewmodel that creates a listbox filled with the possible script choices. I am using a prewritten database system to fill out my viewmodels in an init method in my controller (which I'm not sure is the proper way to do this?).
The viewmodels are as follows:
Imports System
Imports System.Collections.Generic
Public Class ScriptViewModel
[Code]....
I'm trying to work out the functionality. Also, I think this may be too much code in the view, even though most of it is display code.
Anyways, I have two main questions. One, does creating a model in my controller, calling an init method on it, and then passing it to the view make any sense in an mvc context (if not, how would I proceed?). Two, if I want to perform validation on the form I output in my htmlhelper, but I want to use my query model validation (and not my paramviewmodel), how can I do that? Most of the examples I've seen involve a controller that recieves an appropriate model variable, and the binding is performed outside the controller itself. They then just check modelstate. Is there any way I could do something similar here?
Edit: Is there any way I can make the syntax highlighting less crappy?

View 2 RepliesI just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?
