VS 2010 Exporting Partial Access Database
Dec 20, 2011
I have done a small app using vs 2010 with an access database. Initially what my friend asked for, was an app, running on one computer. So local access database was a good choice, i thought.
The app is used for collecting data from different enterprises, and different workers in this enterprises. My friend asks me now: �what if two people are using the app on their computers, collecting data in the same place from different workers. Can I, at the end of the day, export data from one computer to another, so that i have the full information in one computer, in one database?
My answer is that this was not the purpose of the app. Probably we should have looked, instead of a local database, for a web app using a centralized mysql database.
But since that is not the case, and the app is almost finished, my question is: can you do it? Can you partially export some records from different tables, and import them later, so you have the complete actualized database in one app?

I have an access database (made by other application) that I need to read it. The problem I have is that the tables I need to read do not have the read permission; the access permission is set to "Share Deny Write"; though I can open the database in MS Access and export the table to another mdb where I can read it. Is there any way to automate this, or to set read permission on the database using VB.net? Is there any other way to get the info from table not having the read permission?

I'm developing an application where depending on a textfile input i should update/insert some data into an Access database. Let;s say I'm updating the bookshelf of a book according to a textfile that goes like:
TEXTBOOK | BOOKSHELF
000000001 | 000000000A
and so on
[Code]....
does that make any sense? What I'm trying to do is basicalle: check if a book exists, if yes, then attach to Dataset, change its Bookshelf to the one in the textfile and repeat until the file is completely read. The Bookshelf can or not exists, if it doesn't then it should be inserted, is it done automatically when I update the Dataset? Finally "Batch update" the whole Dataset.

I made a program for my friend, a patient database program using VS 2010. I'm worried if my program messes up she loses all the records. Here's what I remembered doing. Maybe you guys can identify how I can fix this or you can give ideas on how to avoid the same mistake.
1. I used Visual Studio
2. I made a VB Windows Forms Application
3. I made a Service-Based Database called Database1.mdf which is a Dataset Model
4. I chose save connection string to Database1ConnectionString
[code]....
She was glad with how simple it was cause I made it with Visual Studio. Now I dunno how to export the database file from her computer/copy of program to make a backup. I dunno what to do.I know I didn't ask for anything in return but if the program messes up I'd feel bad. 1k+ records already jesus christ and the program has like 74 columns/textboxes.

I'm writing a WCF-Service and I split up my service class to multiple partial class files, so every ServiceContract-Implementation gets its own file. I have one file however that should contain e.g. members that are used by every partial class file such as a logger. The service is hosted with IIS 7 if this matters in any way.
[Code]....
The code compiles fine, but at runtime I get an BC30451: The name m_Log is not declared Error (Don't know the exact words for it. I get a german message ;) ). I don't think it has something to do with the type of m_Log or a depending assembly because I get the same error if i try this with a String. What am I doing wrong? How can I make this work? Edit: I was trying the same thing in a simple console application without any problems. :(

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

What I'm looking for is a snippet on how to export data from a datagridview to an access DB. My other question is fairly simple what code would I use once the data has been entered to account for the addition/subtraction. I know these are fairly
simple questions with probably incredibly easy answers, but once again the first time I've picked up a programing language was a week ago. Hey trial by fire works 70% of the time all the time.

I have to generate about 800 excel files from an access database.
For the first 10-15 of them it's working nice, a few seconds/excel file but it's constantly taking longer, at the 150th excel file it's taking 10 minutes.
Here is my code:
It's doing this for each nrliste in the access table (about 800 of them)
Dim lista = From ls In Liste _
Where ls!Concatenare = nrliste(i) _
Select ls

I have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?

What I need to get done here is not a GUI, like the SQL Import and Export Wizard, which can be run from the SQL (2000) Enterprise Manager only, but a code that I can run from within the Visual Basic For Applications IDE from Microsoft Excel 2003, maybe in the form of a module, class or userform or a combination of all three. The best that I have come across so far, was a class that first checks if the worksheet is in a database formattable condition, then creates the database, if it does not exist, a table and then transfers the data from the worksheet to the table.
I have tried the Access 2003 TransferSpreadsheet method, but that does not solve my purpose, because I want to move the data from Excel to Access, starting from the creation of the database itself.

I am using ms-access 2002. I have to export the data of a ms-access table in Fixed Width format. To accomplish this I am using DoCmd.TransferText method.
DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification."
Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with
DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt"
but no success.
For delimited format it is working fine
DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt"
I have gone through the link [URL]
Error message is same as of me but example shown is related to import of txt file.

it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!

I've built my program a database in Access 2010. Works very nice. But I've had a thought. When my program is compiled and I give it out to users. Will those users need a copy of Microsoft Access to use my program. If so, How could I make it so that no install of Access is needed.

I am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?

I have to export the data from the database to .txt file, I have the code below that does export it to .txt file but I'm having problems with this code because the data that I'm exporting is about 5 000000 records, it is quite slow and sometimes the pc can't handle it and stops the exporting.

Im doing a project with .Net 4.0, Visual Studio 2010 and Visual Basic .Net.I needed to add a Chart (the new one included by default in .Net 4.0) that represents temperatures evolving with time, so I added the drawing points in the elapsed event of the timer every second.The graph is doing somewhat ok, but I need another functionality, and this is, every time I stop the timer, save the graph in an excel (.XLS or .XLSX) file. As by default the chart provides with a collection of the type "System.Windows.Forms.DataVisualization.Charting.DataPointCollection", I would like to know if there is a way to create an xml and put the info of those collections in the excel file.I have looked around but I didn't find any similar example, last thing im thinking about is to use an iterative way to manually write in the excel file, but maybe its too much time consuming as the iteration will be of several thousands seconds.

I have connected the database itself without much issue but i want to be able to edit, add and eventually delete from the database using Visual basic interface. This is for an A Level computing course that i teach, i remember a long time ago when i did the course this was fairly simple to do however i cannot for the life of me figure out how to do it at the moment. This is further confused by office 2007 and VB 2010 both of which didnt exsist the first time i did this.Connect 2010 to an access database?
