Oct 7, 2009I have a user control that contains a search value text box a button, and a datagridview to display what the data adapter found. In the data set designer, I have an ODBC connection to a table, with two SQL queries defined FillByCustomerName(NAME), and FillByCustomerNumber(CUSTOMER_NUMBER). If I preview the data in the designer, I see the data expected. The datagridview doesn't show any data. The functions PopulateGridByName and PopulateGridByNumber do the work.

Xml - .NET Xmldatasource Doesn't Show Latest Data On Postback
Jul 14, 2011I've run into a problem that I'm at a loss to understand and/or work around. I'm working on a settings page that updates an XML file. The page has an XmlDataSource with a transform file (to filter and sort the values) and a DataList that is populated from the XmlDataSource. A user can enter a new group name into a text box and click a button to submit the form. When this happens, the new value is successfully added to the XML file.

Checking File Exists Using Data Extracted From Spreadsheet
Sep 8, 2009I have been on MSDN about this and searched but it's not quite telling me what I'm after. I've extracted a list of file names from an Excel spreadsheet and want to check whether they all exist in a directory which a user can select in a text box. It feels like I'm nearly there with it but currently my listbox is displaying everything, I want it to just show the files that are missing. I'm a beginner so I'm not exactly sure if I'm even telling it to compare the two things properly, I've tried a couple of ways of checking if a file exists but neither seem to work.[code]
View 1 RepliesHook Excel - The Process Excel.exe Doesn't Finish After Close Excel
Jul 20, 2010I need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel

The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.

SQL Data To Populate Graph?
Jun 15, 2009I have created a function to create a string to populate a y axis with data:
Function talktosql() As Double
Dim ConnString As String = "Data Source=MARK-WORKMSSMLBIZ;Initial Catalog=Yahoo_data;Integrated Security=True"
Dim SQLString As String = "SELECT [RDSA.L] FROM yahoo_data.dbo.XLON"
Dim SqlDataAdapter1 As New SqlDataAdapter(SQLString, ConnString)
[code]....
so it should for example come out like this:
Dim yValues As Double() = {55.62, 45.54, 73.45, 9.73, 88.42, 45.9, 63.6, 85.1, 67.2, 23.6}
I cannot seem to get the data from the function into the right format to populate "yvalues".(the msgbox that I put in at the end in the first code renders the result "0")

Clear A Picturebox So The Picture In It Doesn't Show Up?
Dec 11, 2011How do you make the image in a picturebox vanish when you change an option? I have tried a few different ways that i have seen but none have worked. I have it set so when i change an option in a listbox it will change the picture and data in other controls, however one option in the listbox has no data to fill in those controls and so gets left blank. However when i click on that option right now the images that were in the picturebox before get left behind until i click on another option that has a picture. So how do i remove the picture from the box?
