Handle .net Exceptions At Application Level

Apr 2, 2009

I was reading a couple of articles a while back which I think described a behaviour where you can, in a .net application (specifically VB.net), allow an exception to occur, and then handle it in some kind of application-level exception handler, as opposed to within a Try/Catch block. My google-fu is weak at the moment, so I'm not having much luck guessing what this feature is called in order to find information about it.

Asp.net Mvc - Handle Application Security Using ActionFilterAttribute And/or SiteMap Authorization?

Jan 12, 2010

i created the following ActionFilterAttribute to check if a user is granted access to a page. I also created two custom Exceptions to handle different scenarios: NotLoggedInException and InsufficientPrivilegeException.

[Code]...

Where do I catch the exceptions to for instance redirect users if not authorized?Should I perhaps use the SiteMap authorization somewhere else instead of using the ActionFilterAttribute and throwing Exceptions..?

note: as you can see I'm using a custom class for BLL.Page. This is a ORM page which has Role based security stored in the database. SiteMap is also populated based on this data

Asp.net - Getting .NET To Handle CSS Files?

Jul 25, 2011

Possible Duplicate: Can .NET intercept and change css files?

I have configured IIS6 to get .NET to handle css files.I did the following steps

Launch IIS Manager Right-click on Default Web Site Click on the Home Directory tab Under Application Settings click on Configuration.Add a new association for .css and map it to .NET executable:

C:WINDOWSMicrosoft.NETFrameworkv2.0.50727aspnet_isapi.dll

How can I check if this is working, i.e. I want to change the default style of a page depending on the url, i.e. if the referer url is http://intranet, it should continue to use the old existing style style1.css, if the referer url is http://intranetv2, it should use the new style style2.css.

Get A Handle On The Correct Way?

Jul 2, 2009

I am trying to get a handle on the correct way and easiest way to do things. By easiest I am not talking about being lazy just accessing and modifying later on. I have started using my own classes and such but I have a few questions. Sometimes I want to create a control on the fly through code instead of using the designer. Should I create this control in the main form file or in a separate class? If I make it in another class it seems harder to access later on. Then again if I dont know that the control is going to be created(user clicks a button to add a control) how can I access it? Also it seems alot harder to access certain things when it is in another class. For example if I create a new window in a class and then want to check if it is there or not it is alot harder to do.

Getting Handle Using Win32 Api?

Jan 24, 2012

I am trying to create a small utility that tracks desktop usage in detail, to the level of individual text boxes etc.... in other applications. However, it is proving quite tricky. I thought I had it nailed using the Windows api. The below code is just a snipet of the code but essentially it provides me the handle of the control that the mouse is over. I thought from here, it would be easy to to the same thing but to provide the handle of the control that the cursor was actually clicked on, for example, if someone is filling in a text box in an application, they would not necessarily move the mouse to get to the text box, they may tab to it. Does anyone know if there is a way to get the handle of the control that is in use?

Private Sub Timer1_Tick(sender As Object, e As System.EventArgs) Handles Timer1.Tick
Dim ptx As Integer = Cursor.Position.X
Dim pty As Integer = Cursor.Position.Y

Handle Results Of More Than 1 Row

May 6, 2009

I am having a SP run in my VB application every 10 seconds to check for any new rows that have been inserted to the database since the last check. What is the best way to do this? Most likely it will be 0 or 1 rows, but I am afraid at random times it maybe more than 1 and so I thought I would fill it in a DataSet, but I came in here to see if there are any other better ways. If dataset is the best way, how do I do a For Each Row in the dataset to process some VB code for each row?

How Does One Handle Handles

Sep 12, 2009

The short program below runs just fine when it is the only item on a form. However, when I put it into the ItemInsertTemplate of a ListView control, I get the following message:

Handles clause requires a WithEvents variable defined in the containing type or one of its base types

Line 30: Protected Sub btnDate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDate.Click

The error message identifies Line 30 as the problem.I get the same message for Sub clnEvent_SelectionChanged How do I correct this?
