Use Two Vesrions Of Microsoft.Reporting DLL's At The Same Time In VB?
Mar 2, 2010
It looks like MS have removed support for nested Business Objects in their Report Viewer 2010 companant. We would like to upgrade our web app to make use of the new features, but need to maintain backwards compat for loads of legacy reports.1: We cant put anything in the GAC as we are on a hosted shared web server.2: We are in VB so dont seem to be able to use Aliases (i think a c# feature), so we cannot add the references in VS at all or we get a namespace conflict or reference already exists error.3: The report web componant dll is itself dependant on two other dlls that are also new (e.g. common.dll and processing.dll)4: The report compnant has to run in the main app domain at the moment using ExecuteReportInCurrentAppDomain) as when it accesses the business objects, they check security roles etc and this did not seem to work if the report viewer ran in a different app domain. This can probably be worked around.

I've been programming for quite a while now and started learning about databases and decided to make a program with a database with it. I made a normal log-in system, but then I don't know how to add information into the database or take out.For Ex:Create account button:
- Creates a new string in the 'Accounts' table
- Then the user can login with that information
The main idea is, I want to be able to insert and delete data from a windows form (the log-in system). And check to see the information, like when users login. Please help, I've tried so many things and don't know how to do what I want with Microsoft SQL.

I've created a VB Console Application Project and am trying to instantiate a Report Viewer object. To my understanding I need to import Microsoft.Reporting.WinForms however Visual Studio does not recognize this name space. Is there some reference I need to add?

It might be funny , but I'll ask anyway : is it allowed to create a program with VS2008 while at the same time it will use the Microsoft framework 4.0 ? I am asking because I use VS2008 while at the same time I have the impression that framework 4.0 is "lighter" than 3.5 .

I have a VB6 application which has been running succesfully for years under XP, however under Vista data loss has been observed.It appears that if the app is run 'as administrator' then it connects to the correct database file, however if the app. is not run as administrator then vista creates a copy of the database (no idea where) - hence I end up with 2 versions of the database.
In fact I can delete the database file entirely and the app. still works fine because vista is using it's own copy - the problem is how do I back up this 'vista copy' when I can't find it (search doesn't find it).

VB.net application crashes without specific error
I developed one application in VB.Net 2010. It worked fine on my laptop. Now when I run this on another PC, it just crashes and give windows error as below.
[CODE]..........................
Along with this.
[CODE]......................
This application required .Net framework 4 & Oracle 9 ODBC drivers, which I installed on new PC.
I am not able to figure out what is the problem exactly, however it seems something with .Net framework itself.

I have an VS2008 VB windows application. I am deploying it via Microsoft .MSI . The target machine parameter is set to x86. When I deploy it to an x64 running XP I receive the following "Microsoft.ACE.Oledb.12.0 Provider is not registered on the local machine". Am I missing something in my setup project to make sure it registers all my components?

In Microsoft Access I use: Hours(time) minute(time) function to get current time hour and minute. I then use loop to add to the minutes until it ends in a 5 or 0 to round it up to the next 5 minutes. e.g. 13:43 rounded up to 13:45 I use IF statement to make sure the minute does not exceed 60 to start the hour. I want to use that time to add hours or minutes to easier e.g. add 15minutes, add 1 hour ect.

I'm developing a chart that is frecuently updated.This chart works with a macro to display the period of time the user wish. The worksheet is protected because it can't be edit by the user. The user can just enter the dates between the period that he wants to be display by the chart. When I use the file on Excel 2003 its runs without any problem. But, when I use it on Excel 2006 or 2010 it gives me the following error:
Run-time error '-2147467259 (80004005)':Method 'MinimumScale' of object 'Axix' failed

But when I run the code the fill method of the DataAdapter, the columns I created are not filled with data, but automatically generated columns appear. How can the columns I created at design time be filled with data?

I have a multitude of VB .NET programs that generate reports in Excel that I populate from an SQL Database locally. My boss wants me to port all these to ASP.net so that users could then access these reports with dynamicly generated results on a browser page.Before jumping onto imbeding Excel objects using ASP.NET from the code I have in VB .NET I was wondering on what kind of approach to use. What could be the most effective way to convert/display these reports in real time to the user via a Browser?

I'm faced with a (fun, actually) data mining problem; I have raw ASCII files from instruments, and I want to move that data (~400 GB) into a database, then be able to run various algorithms determining correlations of time series, etc. I would like to write the mining algorithms in Visual Basic (.net, VS 2010 right now), and be able to do visualizations with VB code I have in hand.On the nature of the data: think of a set of several thousand devices, each recording a measurement at a given interval - so I'm talking time-series vectors. It's not more complex than that - though I may have vectors with holes, etc. - not sure what problems of that sort lurk in the data.I spent today re-acquainting myself with VB.NET's interface to (in one case) a Microsoft Access database. What used to be fairly simple - DAO I think it was - involved tables, recordsets, etc (and that would likely be fine). Now I seem to be required to have a weird variety of generally useless objects, e.g. 'adapters', 'datasets', etc. The problem is that I know exactly what I need, and all this extraneous stuff just gets in the way (certainly in coding complexity and opaqueness, and likely in efficiency as well). If any of these mechanisms gave me a kind of virtual access to the entire dataset, and let me control caching parameters, etc.it might be great, but I found nothing along those lines. It seems like useless bloat, though I suppose it must be useful to someone.Anyway, I tried a number of different approaches, and none seemed at all aimed at what I need to do: efficiently do math on a large dataset. I can't believe I'm the first to have this problem, but I can find no useful wisdom out there. I'd be comfortable with pretty much any underlying database mechanism: MySQL, SQL Server, MS Access, but ideally something generally SQL based (I may eventually have to transition this entire system to draw from a client's SQL database, though that's not an overriding concern now). Other than that I want simplicity and efficiency. I thought my old ODBC techniques would work, and to some extent they do, though modifying tables seemed to have bizarre problems (no errors, but not modifications either).
I do have a fairly aggressive deadline to show some algorithm results, so my focus in the short term is to get something reasonable working *in* the short term - in other words, it's less important to me to pick the 'fastest' relational database than it is to pick a database that lets me focus on coding the algorithms, not working through tedious data access coding. If this db could be any smaller, I'd have tried to do it all 'in memory' at least for proving concepts; I don't want to have to learn an entire jargon and approach just to be able to retrieve data points.Perhaps I'll need to bite the bullet and just write something myself, a .dll perhaps just to save and restore large time series vectors. It seems a bit frightening to me that one would have to do this in this age, what with all the database systems out there, but I don't have much time to work through arcane interface logic.

May i know what is the code to automatically send the current time or date to database once i click the button? Since i'm using:
Label11.Text = System.DateTime.Today
Label12.Text = TimeString
That mean the time will keep on running.. What i want is when i click the button, the current date and time will be recorded.

I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

So I'm guessing it has something to do with the fact that I don't have office loaded on my computer. Now I have another laptop, with office that I loaded this project on, and it works fine. So do I have to load office on this computer, or can I just reference something?
