this is my first try with .net 08 express. i have up graded my project from ((vb6 + ado) & access03)to .net express 08 every thing is almost fine except that the functions i defined with in the standard modules are
becoming inaccessible to the program. there are 4 modules & more than 25 functions & other constants , sub,public variables are defined
a while ago I developed an interface that shows raster maps under VB 6.0 (see, for example, slide 5 "Forest Stand Development" on [URL]
I would like to rewrite the code in VB 2008 (or download open source code) to transfer everything to VB 2008. But rather than just putting a picture control on a form as I did before under VB6, I would like to learn and adopt some new technology while continuing to use classic Windows form coding. WPF technology (see [URL] is way over my head.
I recently upgraded an application that creates several report files, that are read by an older VB6 application that i cannot upgrade. I've gotten everything working (faster than i expected) except the new FilePut. I'm saving the ubound of an array, which is a UDT, Then saving the array itself(which again, is a UDT)No matter what I do, the file is about 7 b larger, and doesnt want to read in at all in VB6. For example, I put an 32 bit integer into the file, say 4000, VB6 reads it as 3948395 or so, it seems its padding the file at the beginning or something.
And Yes, i've tried microsofts ArrayIsDynamic function, but it seems to have made no difference at all.
I'm trying to upgrade sum vb 6 code to vb.net 2008 but I'm getting an error.'AddressOf' expression cannot be converted to 'Integer' because 'Integer' is not a delegate type.How can I fix this.

I have a vb.net app that is installed on server 2008 and registered as a remote app with approximately 70 users accessing it. There is an issue that when I put a new version of the app on the server, every user must remote desktop in and run setup.exe before the app will update to the newest version. If they try to run it without doing this step first, the app just runs the previously installed version under their login.

I am upgrading from Visual Studio 2003 to Visual Studio 2008. ow I should upgrade my project.My project is in Visual Basic.Net, and using an Access 2003 Database. I have four datasets, MainDataSet (for the main data tables) LookupDataSet (for lookup tables States, Countries, Colors, etc) OneFormDataSet (data used on only one form) and ReportsDataSet (data used for reports).I have one form "OleDbAdpatForm.vb", that has all the OleDbDataAdpaters for my project. It also has the DataSets and the OleDbConnection.I have public functions that enable me to load the data tables.
I have a LoadTable function when I can pass a column and a value, and the SQL select command is updated with a WHERE or HAVING, so only the requested data is selected. I also can pass the whole "WHERE ..." part of the SQL select command, so I can have multiple parameters in the SELECT command.On my other forms, I have copies of the DataSets, so I can design grids/controls. In the form_Load events, I manually bind the controls to DataSets and tables in located "OleDbAdpatForm.vb", so all forms are using the same data tables, and changes made to data in one form are reflected in data in other forms.The VS 2008's DataSources, BindingSources and TableAdapters seem much easier to use. how I should implement the new data features in my application?
how I can implement my calendar with VB .net express 2008 and MSSQL 2008 Express. How do I get it to work with datasets, binding source etc.If I go to Properties>settings my connection string is:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|CalendarDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
and I have a table with fields:-
CalendarID
Subject
Location
Purpose
[code]....
I can Add the event to the calendar I have the necessary items on my form linked to my table and I can save them to my table:
Me.Validate()
Me.CalendarTableBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.CalendarDatabaseDataSet)
But I cant keep the event displayed on my calendar when I close it and open it again.
I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
View 1 RepliesI am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

View 2 RepliesWe are upgrading a VB6 project to VB.NET. I ran it though an upgrade utility (Artinsoft). I guess the question is where is the GUI. In VB6, there is a form designe and Object mode. That does not exist in vb.net correct???
It looks like during the upgrade the entire GUI, the forms, the buttons, they are all gone. None of that was upgraded. So does the entire GUI have to be recreated in asp.net or something?
