DB/Reporting :: Fill Access Database Table From Dataset?
Jun 5, 2011I have 2 databases that I am working with. One is a compant customer database and the other is my personal call log. Now I am creating a front end for the Call Log. I was updating my customer list by Importing 2 tables from the customer database, a series of queries would erase all of my info, take all the data from the imported tables and move it into mine then erase the imported tables.
Im trying to accomplish the same in my VB frontend. I can connect and fill datasets from the customer database. I can erase my tables. How do I take all of this data from the newly created dataset and move it over to my empty tables?

DB/Reporting :: Update Database From DataGridView?
Aug 27, 2009I�m trying to make a simple database editor using DataGridView.I have one DataGridView containing a lot of data on products and some parameters on how they should be tested. Some of these parameters, for example "Test method", is just a number. But if I look in the table for Test Methods that number has lots of other parameters. So if I select a "Test Method" Cell and click a button that table opens in a new form with just that "Test Method" (if I for example have selected a cell with the number 1, Test Method 1 will be shown in the new form). So far everything I�ve said works. I can even change values and update it to database in the first "Products" table. So here is the problem The DataGridView that shows the products is bound to a table and always shows the same thing which makes it easy to change and update using the following code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.INPUT_PRODUCTSTableAdapter.Update(Me.TestPlattformDataSet)
Me.TestPlattformDataSet.AcceptChanges() End Sub
This will change later when I add a search function. Then this will need the same modification aswell. The DataGridView thats shows the other parameters can�t be updated using just this code cause I get an error that says
"InvalidOperationException" "Update requires a valid UpdateCommand when passed DataRow collection with modified rows."
It seems like the problem is that because I change the data under run its not really bound to the database. And I haven�t found any complete solution to this. I have found some similiar problems and it seems I need to update each row using the command
TableAdapter.Update(DataRow)
Here follows the entire code for showing the Parameter Table in a DataGridView. This does not work.
Public Class Form3
'ID is the value from the cell selected in the Products table

DB/Reporting :: VB 2005: Actual Database Will Not Update
Dec 19, 2008I have recently wanted to start work on an application that uses an MS-ACCESS database. The problem is that no matter what I do, the actual database will not retain any records added. I have followed the Microsoft examples to the letter and it does not work. As long as I have my app running I can add, edit and delete the records. As soon as I close it and run it again, all the records are gone. The mdb is not read only, I've checked it. I also decided to try the my video collection example program that is included with VB 2005 and it will not retain any records either. Is there any code I need to add to get this to work or is my copy of VB 2005 broken? This is extremely frustration because I plunked down a lot of money for Visual Studio 2005 Professional. This is a key feature and it should work. Microsoft had me do a reinstall and apply a couple of patches and it still did the same thing. They told me either I am not coding it right or my system is flaking out. I did a fresh install of Windows (I even formatted the drive before installing), and reinstalled VS yet again and even with that being the only program on there, it still will not work. So I installed all my programs again, restored my backups and now a day and a half later I am writing this.
View 9 RepliesUpdate SQL Database Through Reading An Excel Worksheet?
May 31, 2012What I'm trying to do is load an Excel file and see through each row; in each row I want each cell in that row to be put into an array which would loop through for the next row.
Through finding the row cells I want to update my database with this information. At the moment I am assigning the excel file to a datagridview because I do not have the knowledge to find another solution after looking across the internet I still ain't come up with a suitable solution.
Upon running my code below; after one minute it crashes with the following error:
"The CLR has been unable to transition from COM context 0x94cc80 to COM context 0x94cdf0 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."
The code below is what I'm using atm (which crashes) but I want to be able to

VS 2010 Fill Excel And/or Print Loop?
Jun 11, 2011I have an Access 07 database I'm using to store my data. I have no problem at all filling a worksheet in excel or a table in word from the textboxes currently on the screen and saving it as a pdf. That's basically how I'm reporting my data from my program.
Where I'm stuck is how can I do the same process for each row in my dataset that has a date or value similar to a filter? I can filter the dataset by adding a query in the dataset designer so it only displays the rows I want to build form reports for, but I don't know how to code a loop to make it work for each row.
Basically I'm looking to find a way to print and/or create pdf form from one button click for multiple records and not just the one currently bound on the screen.

DB/Reporting :: How To Use Update And Also ADOX Use
Sep 14, 2009I am very new to VB.net express and I am getting confused as to what does what. I have to work with DBF files (clipper/ Dbase iii or iv) I have code to create a new DBF file with a reference to ADOX. The code example seems to work. I can open and display a dbf file (from a clipper application) using an oledb.connection This allows me to fill a dataset and bind to and display a grid view. I have yet to succeed in updating the source dbf file.
Does ADOX do anything for me beyond creating a new DBF file?The DBF file is unsorted and not otherwise indexed. For the data massaging and manipulation I may use a temporary sort but the data relations do not need that and the tables are not related.That being said, it appears that the data wizards or command builder will be of little use.

DB/Reporting :: Why Can Not Update A Dataset
May 12, 2010Today i have been checking out the concept of datasets and i like the way they work except for a minor issue i have with it.The following code should get a databasetable and put it in a dataset and return that set to the user.[code]I submit the table name and it will select it, read it and fill the dataset with it, then return it. And it does exactly that once.If i try to re-read the same datatable it just returns the exact same dataset as the first time yet i am 100000% sure that i changed it .
