Migrating 6.0 To Modern Architecture?
Aug 10, 2010We have a small visual basic 6.0 application with an Access DB that we would like to migrate to modern code and architecture. I am not technical, but I am believe this would be something like a .net framework with a SQL Server DB.What I am wondering about, is there any way to covert this code to a modern language/architecture? If so, what is the easist modern language to migrate to?
View 7 RepliesAccess Sessions In Asp.net Handler ?
Apr 13, 2012I am trying to upload images using generic handler as shown below and I have a normal aspx page where I am showing all the uploaded images after uploading.Everything is working fine.
CODE:
Now I want to add a session variable by generating a random string and add the uploaded images to the newly created random string.
1.I have seen this Question on SO to use System.Web.SessionState.IRequiresSessionState for sessions and how do I create a folder with that and add my images to that folder after doing that how do I access this session variable in my normal aspx page.
2.(Or) the better way is create session variable in aspx page and pass that to handler?If so how can I do that?
3 .I am trying to find the control from my handler.Is that possible?If anyone knows how to get this then also my problem will get resolved so that I am trying to create a session from m aspx page.

IDE :: Keep The Size Of The Properties Window Across Sessions?
Apr 10, 2009When I start working on a Project I like to change the size of the Properties Window. (I like to make it taller than it is by default). But each time I start a new Project the Properties Window goes back to the original shape/location. Is there a way that I can customize the layout of that window so that the shape is retained across sessions?
View 6 RepliesVS 2008 Multiple Sessions - Different Web Browsers
Sep 10, 2009I've thought long and hard on how to do this. Since I'm posting here, you see I haven't figured it out. I've found out how to login to a website with GetElementById, but I have another problem. I need to login with multiple web browsers. But when I login on the second, I can't because the session/cookie is already there. I thought usnig a proxy would work, but that just applies to both web browsers. Using the example below, would it be possible to apply this to only one web browser? Or make separate sessions for each web browser control?

VS 2010 Different Applications Share Same Sessions?
Oct 19, 2010just wanted to ask if it is possible to have different applications sharing the same session (i.e. database session)... i'm planning on creating a web-based application and a form-based application using asp.net for web and vb.net for forms but i need to have them share sessions since some global variables will be session based and also authentication to one application should also authenticate on the other.
View 2 RepliesVS 2010 Passing Objects And Sessions?
Aug 21, 2011I was wondering if someone could tell me if this is "bad practice" or is a perfectly acceptable way to pass an object to another form.I've cut out a lot of the code to summarise what im asking.
[Code]...
Dim myRetrievedObject as myObject = Module1.returnSavedObject()Is this a acceptable way of passing an object between forms or is it a completely bad idea?Ideally i would like to be able to "add" further objects to the initially created object in Form1 but then on reloading of Form1 , retrieve the new version of myObject with the newly added objects within the myObject class.My initial thinking is this creates an almost session like state for the initial object. So you can use the same object over all 3 forms or more and just simply add to it like a shopping cart type of functionality.
C# - VB Collection - Convert To A Modern Collection?
Jun 26, 2012I need to convert a VB Collection to a modern one, like Dictionary or Hashtable. For my approach, I need the Collection's KEYS. Googling tells me that it's impossible. Re-writing the entire application using new collections is not an option as the application is really old and large (converted from VB6 to VB.Net).Using the old Collection also is not good - as there are new components in development.Converting a - for example - Hashtable to Collection works:
using VBCollection = Microsoft.VisualBasic.Collection;
public static VBCollection ToVBCollection(this Hashtable table)

Allow Multiple IE Browser Clients With Unique Sessions In IIS 6.0?
Mar 2, 2011I have a ASP.Net VB.Net application, which I developed an deployed in about 2004. I have just upgraded it to a new server and IIS 6.0. The application requires users to login from IE it and maintains their State using sessions on the server. I would like the users to be able to have multiple browsers open, each running with unique data on their client system. Is this possible, if so, what do I need to do?
View 4 RepliesBest Way To Maintain An Autocomplete / Suggest List Across Sessions
Apr 7, 2009I would like to maintain a list of all of the strings entered into a ComboBox across all uses of an application on a given PC, for use as the AutoCompleteSource for that ComboBox, i.e., I enter in "Fred" in the ComboBox, commit the data, close the application, reopen the application, reopen the ComboBox, type "F", receive the suggestion "Fred".Assuming I already have in place code to create and maintain such a list in memory and add new elements to it as they are entered into the ComboBox, etc., what do you suggest as the best way to save/load this data in between sessions?Possible complicating factors: This application will be deployed via OneClick deployment, and will search for updates online every time the application starts. I would prefer that if the application updates, the list still exists after the update has completed.
View 2 RepliesIDE :: WebBrowser Control - Navigate To Page That Uses Sessions
Apr 5, 2010I'm using a webbrowser control in my program and I navigate to a page that uses sessions.

View 9 RepliesUsing Specific Sessions Calls In *.aspx Pages?
Apr 22, 2009I 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
VS 2005 AxMSMAPI.AxMAPIMessages / Sessions Is Not Defined?
Nov 2, 2009Some of you may remember threads I posted a couple of weeks ago about a VB.NET application I've built where I want to have a form open that allows the user to create and send emails. So the form works absolutely awesome on my PC. Day before I went off on vacation, I installed it on my co-worker's laptop and ... it didn't work. The utility starts, but the Email form doesn't work. In the Unhandled Exception error message, AxInterop.MSMAPI Assembly Version 1.1.0.0 is listed as installed; however, when I run the application through Visual Studio2005, I'm getting the two following messages:
Type 'AxMSMAPI.AxMAPIMessages' is not defined
Type 'AxMSMAPI.AxMAPISeession' is not defined
I've gone into the References but the MAPI Reference is not available (which is probably because the assembly is loaded).

View 10 RepliesAjax File Upload Unusual Behaviour When Using Sessions
Jan 30, 2011I have just implemented an Ajax File Upload control that uses a progress bar. I am a little confused. When i use the control on pages that dont use sessions, the progress bar with no problems will show the user the actual progress of the file being uploaded from 0%,1%,2%,3%.......% to 100%. Now when i move this control onto a web page that uses a session, this session stores the user information such as screenname, email, etc... the file uploads with no problems but the problem is that the progress bar does allow the user to see the progress until the file is finised uploading and the progress bar jumps straight from 0% to 100% uploaded and doenst really show the full progress of the file whilst being uploaded.
Why is this behaviour occuring when i use sessions? where the progress of the file being uploaded isn't being shown to the user until the file uploads.

VB - Multithreading With Synclock - Threads With Different Sessions Run Trylock Simultaneously
Jan 31, 2011i have some test code which i run at every load of a page in my asp.net website [Code] the "dotrace" simply add a record to a log table in the db. now the right result would be that i should have the entries in the db in order "entered","exiting","exited" but actually when i look in the db i see first 2 "entered" then 2 "exiting" etc. meaning that the multi-threading is working ok, but not the synclock. is that correct?
and how can this be fixed? the real code will be adding records to the db and might be called from several pages of different sessions, but the same code must not run twice concurrently. if i open multiple pages at once, they still clash some times. but if i'm correct, the issue is now not with the synclock as much as with the httpruntime.cache, because when using a standard property, on one page, the code works 100%. so how can i make sure that 2 threads, even from totally different sessions never run the trylock simultaneously?
.net - Error When Rolling Out Software Revision To Terminal Sessions Instead Of Desktops?
Nov 15, 2010I'm doing some maintenance on some software originally built by my predecessor at the company (who has since moved on to greener pastures). I'm currently rolling out a new version of the software. At this company, the installation procedure is basically to just shove the /bin/Release directory out into our automated program updater's magic directory, allowing it to automatically copy the contents of that directory over to the local /Program Files/ and let the magic happen. The magic always seems to happen, so there's no big issue, there, although it does weird me out somewhat, after many years of .msi installers...
