Using Excel 2007 and VB 2010...I'm trying to have my program select a specific worksheet from a workbook yet my program keeps opening whatever sheet was active at the time of the file being saved last. Here is my code for that
xlWorkbook = xlApp.Workbooks.Open("MyWorkbook.xlsx")
xlWorkSheet = CType(xlWorkbook.Worksheets("My Worksheet"), Excel.Worksheet)
I'm using Visual Studio 2010 (VB.Net) and Open XML SDK 2.0. How do you insert a formula into an Excel 2010 worksheet? When I do this I also wish to set the CellValue property of the cell to a DBNull or EmptyString to force Excel to recalculate the cell when the user opens the workbok.
View 1 RepliesPart 1 of what i want to do is on the Load Event of my form i want to look at an excel worksheet and populate a data table with the data found in the first two columns of the worksheet.
Essentially column 1 is Descriptions and column 2 is pricing
Part 2 of what i need to do is that when a user selects a description from the combo box it populates a text box with the appropriate pricing.
After doing some reading into this all i have seen is some threads on how to use Jet4.0 to link and grab the data but it is my understanding that Jet doesnt work with 64 bit OS.
Nonetheless I need to figure out a way to accomplish my end goal and make it as universal a solution as possible (ie. i do not want it to only run on 64 bit or 32 bit machines)
I try to select the last row like this:
Dim lastRow As Integer = DGV.RowCount
MsgBox(lastRow)
DGV.Rows(lastRow).Selected = True
The messagebox returns the correct number, but when it comes to select that row it says:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
But if I assign it a row, example: DGV.Rows(5).Selected = True
I want to select records from a access table using sql in vb.net 2010 based on what a user types....
My statement is: comm = New OleDbCommand("SELECT * FROM Recipes WHERE RecipeName= '" & TB1.Text & "')", con)
this only selects records where the full word is the only word in the record set.
I want to type say "Vodka" in the search box and then it must return all the records where "Vodka" is ANY part of the record name: ie: "vodka" or "Vodka" (any case letter) or "Blue Vodka" etc.
Is there a way to make a column unselectable? I can make the column read-only but it would be easier if it was unselectable so the user won't be confused trying to enter data into a read only cell. So if I clicked on a cell in that column or moved into that cell in that column it would jump to the next column, or not focus on the cell at all.

I have an application written in VB.net for batch print jobs. As part of the application, the user selects two printer trays to use to print the batch to (one plain paper the other coloured for coversheets and batch seperators) I had this working until we upgraded our systems from Windows XP with Office 2000 to Windows 7 and Office 2010. Now the selected trays are not being recognised and an error is thrown.
I've looked at similar posts on here and other forums but they seam to concentrate on using some word default trays (wdPrinterDefaultBin etc) however I need to be able to let the user pick whatever tray they wish to use. I don't want to have to go through every printer in the building and map the trays to the word values either as I don't want to rewrite the app everytime we've a new printer.
Here is the code:
sub PopulatePrinterTray (byref Printer as String)
'gets printer trays for selected printer and then populates some comboboxes
Dim pkSource As Printing.PaperSource
Dim printDoc As New Printing.PrintDocument

how do I go about selecting a time of day in a form??
I have tried using a datetimepicker but it just selects a date and it displays the static time (current time).
I'm am trying to determine the total number of fields under a particular heading given that the other Heading's total number of fields are > or < than the heading in question. The query, shown first in the attached code, works well if there is one column in one database table, however it does not work well when there are a number of columns with a different number of fields respectively. The CategoriesID encompasses the entire tables contents.I devised a function to determine the total number of fields within a particular column and then attempted to incorporate this, without success, into the second query, shown in the code.
Private Sub GetRandomHeadingFields()
Dim varNumberHigh As Integer
varNumberHigh = TotalNumberofHeadingFields()

It works fine in the IDE on my computer. I built an .msi and executed it on my computer. I get "Error: 53 - Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=14.0.0.0, Culture=neutral,PublicKeyToken=71e9bce111e9429c' or one of its dependencies.

At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

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)!

View 3 Replieswell until a few day ago. I don't know what I have introduced to cause the problem but now, whenever I load the project, VS 2010 (SP1) crahes. If I delete the project's suo file, the project loads (really quickly) and all is well until I exitVS 2010. When I re-run it and try to load the project, it crashes again unless I delete the suo file.The program can be built for x64 and x86. Now, when I reload the project (after deleting the suo file), it comes up in Debug - Any CPU mode. I can change from Debug to Release and from Any CPU to x86 but if I try and change from x86 to x64, VS 2010 crashes.This is not always the case though. If I build the x86 version and then switch to x64, all is well and I can build the x64 version. Obviously, there's something wonky going on.
