View 2 RepliesI am using specific sessions calls in my *.aspx pages and i have 2 questions related to this:
1-Is there a difference between using this type of session declaration in your aspx age?
HttpContext.Current.Session.Item("Whatever") VS Session("Whatever")Would this give the same information for a specific user?
2-Is using Session really User Specific data? I know you can share information using cache but is there possibilities that we have 2 different users (different browsers) that would share information threw sessions. Keep in mind that i am using SQLStateServer for my sessions

View 2 RepliesWhat the Win32 API is? I have looked around but no where really outlines what it is. Is it basically a set of procedures, outlined by Microsoft for programmers in order to get services from the operating system? In essence is it the equivalent to making system calls abd and library calls in UNIX? And yes I now Windows makes library calls too.
View 2 RepliesI have a VB6 project that I'm converting to VB 2008. There is a routine in this project to LoadArrays.By passing the proc name and arrayName I want the info loaded into, I can set up a series of calls at application load and have these arrays available throughout the application (Info is used in many areas to populated controls)This routine makes use of Getrows.Example:arraydef = rs1.GetRows.This will load all fields and records into the array.Is there an equivalent in 2008?

View 2 Repliesso in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.
For example, I'd take in a line of the series of lines: hello:world@yay
I'd want to break it into three separate strings of "hello", "world", and "yay".
How would I do such a thing in VB.NET?

View 4 RepliesThere is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

View 2 Replies[URL] In my Windows Form, I wanted the user to give an option to draw all over the form. But, if the user while drawing, enters the region 1, I want to assign a value to variable, say a=1. Correspondingly, if the user without leaving the mouse button previously enter the region 4, I want to b=1.After the user leaves the mouse button, I wanted to compare a and b. If both of them are equal, then Result=Done else not.

I have made a simple vb application and have used vb 2010 to create it, which all of you would know, uses .NET Framework 4.0. I wanted to use this application at work, however, I found out that my work uses .NET framework 3.5 sp1.
So my question is, is there a way to compile something in VB 2010 that will work on .NET 3.5 sp1? If so, how?

View 1 RepliesSo I'm developing an application in VB2010. The idea is to perform CRUD operations (more or less) to an Access2003 Database.

Controllers for each Use case (which are basically CRUD operations) would create Domain Layer object. Yet I don't know yet how to manage the mapping of the objects to/from the database.
View 8 RepliesI have a thread in an application which calls a sub routine Main(). The Main sub routine in turn call several sub routines/functions from with the same module,several different classes in the same application. Also some sub routines/functions call routines from a class library. Now say the routine/function in class library goes into a infinite loop and never returns. I would like my thread in the application to raise a event and display message to the users about the infinite loop. I am giving some sample code for the application.
