Web Development And Had Some Session A Couple Of Days Ago?

Jan 13, 2009

Very new to web development and had some session issues a couple of days ago. I have those now resolved but having trouble telling the page to redirect home after the session expires.

Using the example from my previous post:[URL].. I have this set in areas of my main page in order to redirect if the session has ended.

If Session("UserClassInstance") Is Nothing Then Response.Redirect("Login.aspx")End If During the testing; after Session_End fires, I go to the control that contains the above statement but seems to think that the session not nothing and will not redirect.

Program Pulls Data From A Csv File Into A Readable Form Written In VB - Works On Couple Of Machines But Not On Couple Of Others

May 29, 2009

I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?

The error output is:

see the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

Exception Text

CODE:

JIT Debugging

To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.

For example:

CODE:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

Asp.net - Adding A Session ID To A Link For Automatic Session Start?

Dec 8, 2011

I am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

Sep 28, 2010

I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)

Class SELF That Is Hosted By A Couple Different Classes?

Jan 16, 2010

I have a class SELF that is hosted by a couple different classes. Basically, the hosting class HOST calls a method in SELF. SELF is passed HOST as an argument in the constructor, so SELF can call methods in HOST. In normal situations, a call to HOST will do something minor, then return so that SELF can continue. However, for one particular type of HOST, one of the calls from SELF to HOST will cause HOST to call SELF, and so on ad infinitum. A classic, though convoluted, case of recursion. Once again, this is only going to happen for one type of HOST. For other types of HOST, that particular call will not cause HOST to call SELF, so there will be no recursion. Nonetheless, there is no getting around it in one case.

I can see two means to decouple the recursion, and I am wondering which one (or a third) would work best:

1) Add a timer into that particular HOST so that the call from SELF that would trigger the recursion would actually just start the timer in HOST, then return. When the timer ticks, HOST can call SELF. The recursion is broken because the call to SELF is done on the timer event, and not when SELF called HOST.

2) As it happens, HOST makes the first call to SELF in a background thread, which means I don't really need to worry whether this thread blocks or not. Therefore, I could have this background thread spawn a second background thread to make the call to SELF, then have the initial HOST thread JOIN on the second thread. This means that the initial thread will block until the second thread finishes. Meanwhile, the second thread will call HOST, and the HOST won't call back to SELF, it will just return like all the other HOST objects would do. This will allow the second thread to run to completion. When the second thread completes, the first thread will take over and call SELF again on a new second thread. Therefore, the recursion is broken because the secondary thread will always run to completion, and the primary thread will wait for the secondary thread to complete, then call it again.

I tend to prefer the second option, because the first option involves a pause of some length (the minimum for a timer, which is pretty small), while the second doesn't, but the first option is actually a little easier to implement.

Filesystemwatcher That Watches A Couple Of Folders

Oct 22, 2009

I have a filesystemwatcher that watches a couple of folders! The files coming to the watched folder are coming from a server. And for some reason the created event is not raised..If i move the files for a sec from the watched folder to a another folder and then copy them back to the watched folder it all works fine! Strange.So if the created event is raised from the same computer that the service is installed on it works great, but not if the files are coming from another computer.

Loosely Couple A Process To A User Interface For VBA And / Or .Net?

Sep 22, 2011

In fact, the process is being written into a library to be pulled in from other applications. However, how do I provide a way for a WinForm to subscribe to the process to update as the process gets executed? I've open this question from both VBA/VB6 and .Net because its part of the gamut for UI development.It's also worth mentioning that these are subroutines and not classes that are running the methods, so event raising appears to be out of the question.[code]

SkinCrafter Light Has A Couple Of Bugs With RichTextBoxes?

Feb 16, 2009

When I downloaded VB 2005 Express I took advantage of the bundle of goodies on offer and downloaded SkinCrafter Light.I really like the four skins that come with SkinCrafter Light, and I am using one on my current project (example of the skin I am using here). However, SkinCrafter Light has a couple of bugs with RichTextBoxes (these bugs are known to SkinCrafter, as I can see posts about them in their forum, but they have gone unanswered in over two years!)One bug is that any text that is colored in a RichTextBox is turned back to black when the skin is applied, and if you click anywhere in the RTB the application will crash (you can see my RTB on the right bottom of the form in my screenshot above).

I use colored text in my RTB, but, at a pinch,I could make do without (as I really DO like the Skin), but the problem remains of crashing when clicking inside a RTB.I was wondering (can't test at the moment as I am at work) if simply placing a control, such as a Button, Label, Picture box etc, set to transparent, over the top of the RTB, would solve the problem, so a user could not click inside the RTB (but would be clicking on the invisible control over the top instead).

I am in the following situation: I have been requested to write an application for managing where we have customers - this must flag up when we try to add a customer too close to another one, so must be able to calculate distances based on post codes.I have chosen to use ASP.Net VB because I am fairly good at that and I like that the browser does all of the layout for me (using Java or C# would mean having to position each element individually).I have copied a few files from the company's website (which I also wrote) and modified them to account for the database structure we need for the new app.I have designed the database to account for the requirements of the new app.I have set up a website in IIS on port 81 through which to view the app.

i've been searching for a way to delay a part of my program to let another part load, all i have found is threading sleep and one way which uses huge amounts of processing power. does anyone know a simple way to pause a part of script for a couple of seconds and then letting it run again? ( the problem is i need to get values from core temp, i also need to open it in the program. at the moment it say's "Object reference not set to an instance of an object." because it hasn't loaded by the time it is tried to be accessed. )

VS 2010 - Insert A Couple Of Fields Into A Csv Config File And Then Update All Other Rows

Dec 19, 2011

I'm trying to insert a couple of fields into a csv config file and then update all other rows in the file at the same index by copying the previous 2 entries. I'm reading through each row and converting the row into a list(of String) because it seems to be the most flexible way. Ine initial insert works fine, but the code below doesn't. The actual insert code is:

[Code]...

pcIndex is the list index value from elsewhere in the code at the insertion of the 1st of a pair of values into one row. I need to update that index point and pcIndex +1 in all other rows. However it's not doing anything. Tried using lstSteps.Insert, InsertRange, etc. Am I using this right? Is there a better way? It seems to be over-writing the entry rather than inserting a new column and moving the others up, so it appears the list capacity value isn't updating - so I'm left with the initial row with 4 more entries than the others sticking out of the file.
