I am trying to upgrade the btrieve code written by Jim Kyle in the early 90's to VB.NET and am running into a problem with unioned structures. The old C code is as follows:
typedef struct {
union {
struct {
PGPTR PgSeq; // 00 - page number
[code]....
One issue I am running into is that VB.NET doesnt like two struct variables with the same name (Usage). What am I missing to group the overlapping fields with a unique struct name as is done in the C example (v5 and v6)?

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.
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

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 realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3
Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.
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?

when i run code after 60 sec it display following error what is this error and how to eliminate ?ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x2040a8 to COM context 0x204218 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

I have been tasked with upgrading a large web application from .net 1.1 to 3.5. I have converted it using Visual Studio 2008, and it compiles ok. Should I be expecting everything to work correctly straight off? And if not can anyone suggest what are the major pitfalls I should be looking out for. Should I be taking the time to write and carry out a full test for the entire system, or is that overkill?
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?
