Updating Very Old Code?
Jan 19, 2011I need to bring an old program back to the land of the living. This is a GUI software package that interfaces to a hardware device. The program was written in VB, but I don't know which version. It was written around 1994. I need to update it to VB.NET 2008. I would normally just observe how it works and rewrite it, but in this case, there are special codes that are passed to and from the device it is communicating with, along with specific formats of data. All of this would be very difficult to decode using a scope or by capturing bytes. I believe I'd have much better luck looking at the source code. I have the source code, or so it is labeled. I have a number of files ending in .frm, .bas, .vbw and .mak. I've tried opening these in VB.NET, but all I get are numbers. MS Word just shows a few symbols. Are these source code extensions from early VB?

View 2 RepliesIDE :: 2005 Application/Form Code Not Updating
Oct 15, 2007I have a VS 2005 VB.NET Windows forms application that is exhibiting very strange behavior. I can add controls to any of my forms and see them at design time, however when I run the application, it resorts to "old" copies of the forms without the new modifications. Also, the application does not seem to be firiing the correct events - when I put a break on the Form_Load event of my main form - it never fires the event when the application runs. If I change the project settings to start with a new form - it does not recognize the change. Something strange is going on and I am quite frsutrated trying to figure it out.

View 1 RepliesDataset Not Updating When Bound Text Fields Are Changed In Code?
Sep 1, 2009I am having issues understanding why it is that a text box that has been bound to a dataset correctly updates that dataset when the text in the box is manually changed i.e. by changing it using the keyboard but the dataset does not recognise the change when I change it in code.Am I missing something obvious? The text is changed in code when the user clicks on a command button that copies the text from another textbox on the form to this textbox.

As i mentioned, manually it works fine but when I use the comman button to change the text it does not recognise that any changes have occured.

Updating Child Collection Of POCO (adding/updating/deleting) In Entity Framework 4.1?
Jan 25, 2012I have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)
On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):
[Code]...
This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.

View 6 RepliesVS 2008 EXE Updating Itself?
Nov 4, 2009I have made an updater program which updates several files used by another application (again made by me). It works great. But when it comes to updating the updater itself I was in a dilemma.My updater program can download a file from the server but because it is running it can't update itself. I wanna know what would be the best way for the updater to update itself.
I thought after the updater downloads its own new executable i would run a .bat file which would remove the old updater and rename the newly downloaded exe. But again as the updater runs the .bat file and shut down itself, there could be a violation.How can updater update itself in the best way ? (just need a way for updater to get a new exe and get it replaced)
Note: Updater is a single exe application made in .net 3.5. It updater another application by downloading and replacing files.
Updating Database From VB 2008?
May 30, 2012I am trying to get information into a database from VB 2008. I have an established connection and have pulled fields onto my form. I am able to see data already in the database on the form. Originally, I tried to use an Update button to send the data from the dataset to the database. This did not work. I then added a Save button to the Navigator on my form in hopes this would do it. This too, failed.

VS 2008 Updating Of The .exe File That Is Somewhere Else?
Jun 1, 2010Right so I have my piece of software, it's complete (for now) and I want to get the final version of it and send it away. Once sent away the only way I'll be able to update it will be via a DVD or maybe if they download the update online.This is what I wanna know: I am just using the .exe file from the Debug folder, is this the right way? Do I need to compile it first and do a proper saving of the .exe file?Is there a way to specifically do the updating of the .exe file that is somewhere else? At the moment my thoughts would be to just copy the .exe file from the debug folder and wack it on a disk with a bat file that xcopys it. Is that considered the right way to do it?

[2008] DataGridView Not Updating?
Mar 9, 2009I'm populating a DGV from a DataSet... all done by code. I have the properties set to allow editing, etc. However, when I make changes to a record, they're not updating back to the Database. I suppose my assumption that by setting the properties to allow editing would automatically write the changes back to the database were wrong. Do I have to write update, delete, etc. commands?

Writing File/Folder Sync Prog, Result Text Boxes Not Updating Untill After All File Action Is Done Even Though Update Code Comes Before Copy?
Apr 12, 2011I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

Updating Some Fields In Sql Express From Vs 2008
Dec 17, 2010I'm using a SQL Express 64 database on a separate server virtual machine. I've been developing my app for some time now in VS2008 on XP SP3. Using .Net 3.5 I've just come across a strange problem. If I update a checkbox from unchecked (the default) to checked, it saves OK. If I click to uncheck it, the change does not get saved. I'm using the UpdateAll method. I tried a single Update command as well, just for that table, but it was the same.
