The Global.asax file is in the root application directory. While Visual Studio .NET automatically inserts it in all new ASP.NET projects, it's actually an optional file. It's okay to delete it—if you aren't using it. The .asax file extension signals that it's an application file rather than an ASP.NET file that uses aspx.
The ASP.NET page framework recognizes automatically any changes that are made to the Global.asax file. The framework reboots the application, which includes closing all browser sessions, flushes all state information, and restarts the application domain.
The Global.asax file, which is derived from the HttpApplication class, maintains a pool of HttpApplication objects, and assigns them to applications as needed. The Global.asax file contains the following events:
* Application_Init: Fired when an application initializes or is first called. It's invoked for all HttpApplication object instances.
* Application_Disposed: Fired just before an application is destroyed. This is the ideal location for cleaning up previously used resources.
* Application_Error: Fired when an unhandled exception is encountered within the application.
* Application_Start: Fired when the first instance of the HttpApplication class is created. It allows you to create objects that are accessible by all HttpApplication instances.
* Application_End: Fired when the last instance of an HttpApplication class is destroyed. It's fired only once during an application's lifetime.
* Application_BeginRequest: Fired when an application request is received. It's the first event fired for a request, which is often a page request (URL) that a user enters.
* Application_EndRequest: The last event fired for an application request.
* Application_PreRequestHandlerExecute: Fired before the ASP.NET page framework begins executing an event handler like a page or Web service.
* Application_PostRequestHandlerExecute: Fired when the ASP.NET page framework is finished executing an event handler.
* Applcation_PreSendRequestHeaders: Fired before the ASP.NET page framework sends HTTP headers to a requesting client (browser).
* Application_PreSendContent: Fired before the ASP.NET page framework sends content to a requesting client (browser).
* Application_AcquireRequestState: Fired when the ASP.NET page framework gets the current state (Session state) related to the current request.
* Application_ReleaseRequestState: Fired when the ASP.NET page framework completes execution of all event handlers. This results in all state modules to save their current state data.
* Application_ResolveRequestCache: Fired when the ASP.NET page framework completes an authorization request. It allows caching modules to serve the request from the cache, thus bypassing handler execution.
* Application_UpdateRequestCache: Fired when the ASP.NET page framework completes handler execution to allow caching modules to store responses to be used to handle subsequent requests.
* Application_AuthenticateRequest: Fired when the security module has established the current user's identity as valid. At this point, the user's credentials have been validated.
* Application_AuthorizeRequest: Fired when the security module has verified that a user can access resources.
* Session_Start: Fired when a new user visits the application Web site.
* Session_End: Fired when a user's session times out, ends, or they leave the application Web site.

I am new to using crystal reports, im creating a report and i have designed some boxes which will contain text taken from the database at runtime. I enabled the "can grow" option of the boxes since the text can vary from being small or large. My problem here is, in my desiging process, i have to draw the maximum box size my text can be which distorts the design over all. What i want is that i draw a small box, enable the can grow option and it grows with the text, but when that happens, the box below the first one is overlapped with its text...how do i avoid this overlapping? i want the boxes below to move along with the text like in a table in word and not to overlapp...or is there a way i can position the boxes at runtime by calculating where they lie??? HOPE TO GET HELP!

Hi all,

You really can't open and parse the Word document this way. The Word doc is a multiple stream format that's VERY complex to interpret. A better option would be to create an instance of Word and have it open the document so you can do what you want to it.

If I recall correctly there is an asc() function that will give you the number value of letters.

i dont know where the dates in your code coming from.... but you can easily have the weekdays from a date......
the code is ..........
Dim myDate as Date<br />
Dim dayOfWeek as Integer=myDate.DayOfWeek<br />
if myDate is a MONDAY then dayOfWeek will have 1 and So on.....
you can check for the SUNDAYS in your dates by that.....

Dim dtMyDate As Date = Today()
You can loop through the dates and check as follows
if dtMyDate.DayOfWeek = DayOfWeek.Sunday then ...

Hi all,
i am pretty new to VB and i got one problem for which i can't find any answer (sorry if i'm simply too blind and this was already answered). Maybe i also start with too difficult issues.
Anyway, i'll just ask.
Is there any way to access the properties of a service and to display these information in a ListView?
In more details:
I got an application developed as a Windows Service. This application can be used several times as a service which means several instances of this service can be created.
My problem is that i would like to display the path the original exe-file of the according service/instance in a ListView.
I already managed to get the name an current status of the according service but i can't manage to display the according path.
I'll put a part of the code here (please be forbear with me i'm beginner):
--------------------------------------------------------------------------------
ListView is called LstGenvSrv
'List
LstGenvSrv.View = View.Details
LstGenvSrv.Clear()
'Columns
LstGenvSrv.Columns.Add("Service", 300, HorizontalAlignment.Left)
LstGenvSrv.Columns.Add("State", 70, HorizontalAlignment.Center)
LstGenvSrv.Columns.Add("Registered File", 350, HorizontalAlignment.Left)
Dim RunningServicesXXX As ServiceProcess.ServiceController
Dim ServiceList As ListViewItem
For Each RunningServicesXXX In ServiceProcess.ServiceController.GetServices()
If RunningServicesXXX.ServiceName.StartsWith("XXX Service") Then
ServiceList = New ListViewItem(RunningServicesXXX.DisplayName)
ServiceList.SubItems.Add(RunningServicesXXX.Status.ToString)
I played around here but i am not able to... 
LstGenvSrv.Items.Add(ServiceList)
LstGenvSrv.Refresh()
End If
Next
--------------------------------------------------------------------------------
In Column "Registered File" i'd like to display the path to the original exe-file for a better overview.
Is this easily possible? The only other possibility i know is by accessing the Registry. Searched through all items of ServiceProcess / ServiceProcess.ServiceController but did not find anyhing.
Some person told me to use some API-Functionality but i thought with .Net this is more or less obsolete.
Thanks for your help.

Can you tell us what the error is? Knowing what exception was thrown and the message helps a lot in determining what the error is so that a solution can be found.

|

An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll"
this error occur

I'll repeat my request with the important bit highlighted: Knowing what exception was thrown and the message helps a lot in determining what the error is so that a solution can be found.

What do you mean with a "hyperlink text"? Is that a label that is made to look like a hyperlink, or should you have asked this question in the Web Development forum instead?
