View 5 RepliesDB/Reporting :: Data Formatting Lost In Translation?
Jun 19, 2009I have an APP that reads data from MS Access tables. It all works fine except that the numbers in Access table are formatted like 800001 so when the user puts "2" in the access table, it changes to 800002 and so on. I want to read the data AS THEY APPEAR in VB.Net but it reads them without the special format. So I get 1 or 2 etc.
I know how to format the data within VB but I don't want to hard code that as the format in MS Access might change. Is there anyway I can read the data format in MS Access ?

C# - Tab Data Lost On Selected Item Changed MVVM?
Mar 23, 2012I have been trying to do this for ages and having no joy whatsoever.
I have a ribbon window of the following hierarchy:
MainWindow
MainContent (Tab Control)
TabContainerViewModel
ViewModelBase
View model base has an ObservableCollection of tabs type ViewModelBase. The Tab Control itself is binding fine to these, displaying appropriate view models. I have 2 problems however, I want a "NotepadView" (Of type viewmodelbase) to be replicated numerous times (one view many view models).
At the minute, I have 4 views (NotePadViewModelx where x is 1-4) with corresponding viewmodels, this is because each view had the same text per tab. Now I have individual views per tab.
When I type into tab 1 and switch to tab 2, I lose what I typed in tab one when I click back.
IDE :: Add Data From DataGridView To Database When The Current Row Lost Its Focus?
Oct 3, 2009I have a small doubt: (VB.Net 2005, MS-Access 2007)Is it possible to add the current row from DGV to DB as soon as the row lost its focus..i.e. whenever i add a new row in DataGridView it should automatically get inserted into the database without pressing any buttons... Bcoz i need to add more new rows dynamically & hence i find little difficult in clicking the ADD button again and again to insert each and every Record.

Importing Data To Excel?
Feb 19, 2010I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "
Private Sub Import()
[Code]...
After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.
Importing Data Using SQLBulkCopy?
May 25, 2012We have a legacy application that is dumping large volumes of data to tab delimited files.Each file contains a single record type and all fields are fixed length.These files can readily be imported into corresponding tables in our SQL server database using the BCP utility from the command line.We have a VB.Net program written in VS 2003 that imports these files using the SQLDMO.BulkCopy routine. We are updating the system to use VS 2010 with SQL Server 2008 and according to the Microsoft documentation SQLDMO is no longer available.I have searched on the internet and have rewritten the import routine to import the tab delimited files into a DataTable using the Microsoft.Jet.OLEDB.4.0 provider. The SqlClient.BulkCopy object is then used to import this DataTable. This issue I am having is that fields in the tab delimited file that are set to spaces are being treating as NULLs when imported into the DataTable. When the DataTable is processed by the SqlClient.BulkCopy the copy fails because the null values are rejected by the SQL table fields that are defined as NOT NULL.Code being tested is shown below
