Thanks for the message, big bro. Yes, an excel window opens and the worksheet has no data in it.

Well, I guess then you have to run it through the debugger and make sure your DataGridView actually has data in it.

I hope you should just be able to use it as is:
Sub datagridToExcel(filename As String, source As DataGridView, header As String, footer As String, convertToXls As Boolean)
' use a static file path for the moment
'Dim BackupPath As String
Dim datatable As DataTable = CType(source.DataSource, Data.DataTable)
Dim Headers As String = String.Empty
Dim TempRow As String = String.Empty
Dim SeparationMarker As String = ControlChars.Tab
'Dim FolderBrowserDialog1 As New System.Windows.Forms.FolderBrowserDialog()
'FolderBrowserDialog1.ShowDialog()
'BackupPath = FolderBrowserDialog1.SelectedPath
If filename <> String.Empty Then
If File.Exists(filename) Then
File.Delete(filename)
End If
Dim SW As New System.IO.StreamWriter(filename, False, System.Text.Encoding.Unicode)
' get the column header names and add to the backup file
Dim i As Integer = 0
If Not header = String.Empty Then
SW.WriteLine(header)
SW.WriteLine(String.Empty)
End If
' add the headers
For i = 0 To source.Columns.Count - 1
Headers &= source.Columns(i).Name & SeparationMarker
Next
SW.WriteLine(Headers.ToString)
' add each row
For Each row As DataGridViewRow In source.Rows
For a As Integer = 0 To datatable.Columns.Count - 1
'check if it's null
If IsDBNull(row.Cells(a)) Then
TempRow &= String.Empty & SeparationMarker
Else
Dim fmt As String = String.Empty
For gridIdx As Integer = 0 To source.ColumnCount - 1
If source.Columns(gridIdx).Name = datatable.Columns(a).ColumnName AndAlso source.Columns(gridIdx).DefaultCellStyle.Format() <> String.Empty Then
fmt = "{0:" + source.Columns(gridIdx).DefaultCellStyle.Format() + "}"
Exit For
End If
Next
If fmt <> String.Empty Then
Dim tmpdat As String = String.Format(fmt, row.Cells(a).Value)
tmpdat = tmpdat.ToString.Replace(SeparationMarker, String.Empty)
TempRow &= tmpdat & SeparationMarker
Else
TempRow &= row.Cells(a).Value.ToString.Replace(SeparationMarker, String.Empty) & SeparationMarker
End If
End If
Next
TempRow = TempRow.Replace(vbCrLf, String.Empty).Replace(vbCr, String.Empty).Replace(vbLf, String.Empty)
SW.WriteLine(TempRow.ToString)
TempRow = String.Empty
Next
If Not footer = String.Empty Then
SW.WriteLine(String.Empty)
SW.WriteLine(footer)
End If
SW.Close()

Hi all,
I'm looking for a good library that is able to read/detect barcodes inside a pdf file.
Until now I only found paying ones who are quite expensive and the customer where I work for is a small company that starts with digital archiving but where we need to be able to detect barcodes in tiff and pdf files.
Can anybody advise me a component for this that is not paying ?
Kind regards,
Vincent

I need a help to add a DTPicker in a column of VSFlexGrid or grid in vb6.0.
Is anyone have suggestion or answer ? Plzz reply as soon as possible.
Thank You.

VB6 is deprecated; it is no longer actively supported.
If memory serves correctly, you'd have to position the control by hand to have it on the location in the grid where you want it.

This is related to my post in the database forum from yesterday.
So I took the knowledge from my post below, and applied it to all my other stuff that required it and everything works fine. But I have a question.
I'm led to believe that you can do multiple Joins, but can only do 1 Group By
I have this sql linq statement, and it would be cool or efficient to just get it all in 1 call.
Right now, I just made another statement to get the vendor info.
I not even sure if it's possible to do.
Here's what I have right now.
I thought Group By pi.PartNumber, vi.VendorID Into productsSold would do the trick
perhaps it should be Group By { pi.PartNumber, vi.VendorID } Into productsSold
But then I understand the first Select product = productsSold, the group,
It seems you can only do it once, or you have to group all the Joins into it somehow. This is the part I'm fuzzy on.
Dim m_startDate As DateTime = New DateTime(2015, 1, 1, 0, 0, 0, 0)
Dim m_stopDate As DateTime = New DateTime(2015, 8, 31, 23, 59, 59, 999)
Dim p_PartNumber as string = "24-FLP44"
using context As New DBContext()
Dim pResult = _
(
From cohc In context.Order_History_Cart
Join pi In context.ProductInfo On cohc.PartNumber Equals pi.PartNumber
Join vi In context.ProductInfo_Vendors On pi.VendorID Equals vi.VendorID
Where cohc.PartNumber = p_PartNumber _
And cohc.OrderDate >= m_startDate _
And cohc.OrderDate <= m_stopDate _
Order By cohc.PartNumber
Group By pi.PartNumber Into productsSold = Group,
totalQty = Sum(cohc.Qty),
totalCost = Sum(cohc.Qty * cohc.Cost),
totalPrice = Sum(cohc.Qty * cohc.Price)
Select product = productsSold.Select(Function(m) m.pi).FirstOrDefault(), totalQty, totalCost, totalPrice
Select
product.PartNumber,
product.MPartNumber,
product.Cost,
product.Price,
totalQty,
totalCost,
totalPrice,
vendor.contactname,
vendor.streetAddress1
vendor.streetAddress2
)
pResult.Dump()
end using

This is a different problem, but basically the same as I posted in Database.
The difference is that my issues are VB based, and not really database related.
So I can sort of see how to do it in C#, but it doesn't translate to VB EF 6
I can't figure it out. I'm close on it.
So I wrote this years ago, works fine in TSQL. It's an Order Table, that has a SalesTax State Code and SalesTax collected columns. It joins a Table called SalesTaxStates, on the StateCode, and the TSQL Sums up the Order SubTotal and SalesTax, and then gets the StateName, TaxRate.
"DECLARE @startDate AS DATE; " & _
"DECLARE @stopDate AS DATE; " & _
"SET @startDate = DATETIMEFROMPARTS(@Year, 1, 1, 0, 0, 0, 0); " & _
"SET @stopDate = DATETIMEFROMPARTS(@Year, @LastMonth, @LastDay, 23, 59, 59, 999); " & _
"SELECT " & _
" sts.StateCode " & _
", sts.StateName " & _
", sts.HasSalesTax " & _
", SUM(oh.SubTotal) AS SubTotal " & _
", sts.StateTaxRate " & _
", SUM(oh.SalesTax) AS SalesTax " & _
" From ORDER_HISTORY oh " & _
"LEFT JOIN Shipping_TaxStates sts " & _
"ON sts.StateCode = oh.SalesTaxState " & _
"WHERE oh.OrderDate > @startDate " & _
"AND ohOrderDate < @stopDate " & _
"GROUP BY sts.StateCode, sts.StateName, sts.StateTaxRate, sts.HasSalesTax " & _
"ORDER BY sts.StateName "
I have tried many things today.
I tried a Group Join Into xxx = group
I tried Group By oh = new With / Select New With group.Sum(function(m) m.Qty)
In each case, I can the oh stuff and the sums, but I can't access the Join columns for taxRate
So below is a stable version that works with oh. I figure I'll post something that works rather than complete slop.
Dim m_startDate As DateTime = New DateTime(p_Year, 1, 1, 0, 0, 0, 0)
Dim m_stopDate As DateTime = New DateTime(p_Year, p_LastMonth, p_LastDay, 23, 59, 59, 999)
Dim context As New DBContext()
pResults = _
(
From oh In context.Order_History
Where oh.OrderDate >= m_startDate _
And oh.OrderDate <= m_stopDate _
And oh.OrderStatus = "COMPLETED"
Group By oh = New With
{
oh.SalesTaxState,
oh.SubTotal,
oh.SalesTax
} Into Group
Select New With
{
.StateCode = oh.SalesTaxState,
.subTotal = Group.Sum(Function(m) m.SubTotal),
.salesTax = Group.Sum(Function(m) m.SalesTax)
}
)

Something like this should work:
From oh In context.Order_History
Join sts In context.Shipping_TaxStates On oh.SalesTaxState Equals sts.SalesTaxState
Where oh.OrderDate >= m_startDate And oh.OrderDate <= m_stopDate And oh.OrderStatus = "COMPLETED"
Group By sts.SalesTaxState Into GroupedHistory = Group, SubTotal = Sum(oh.SubTotal), SalesTax = Sum(oh.SalesTax)
Select State = GroupedHistory.Select(Function(m) m.sts).First(), SubTotal, SalesTax
Select State.StateCode, State.StateName, State.HasSalesTax, SubTotal, State.StateTaxRate, SalesTax
Order By StateName

Oh I see what I was missing now.
The Select statement, that selects the group of records first from the Group
And then do the select.
I was baffled, kept getting missing type, missing ), conversion failed for Decimal, etc.
I would of never figured it out, not many vb examples online, plus the VB was slightly different like = Group.
Thanks Richard!

Probably because you did not show that you had attempted anything, reversed.

I down-voted the question, and having slept on it, I stand by my decision.
The OP has clearly made no effort to answer their own question. If you paste the question into Google, the answer appears within the first 10 results.
But why bother asking Google, when you can paste your question into a forum and get someone else to ask Google, sift through the search results, and present the answer to you on a silver plate? After all, this site was created to be a human search-engine, providing help to those who can't be bothered to help themselves, wasn't it? 
And no, I didn't post an explanation for the down-vote. In my experience, that only leads to insults or arguments from the OP. I have yet to see anyone accept the criticism and adjust their approach to the site.

Thanks for the explanation!
I agree that the OP could have Googled and tried to find solutions. However, another aspect is that if you don't quite know what you're looking for where do you start from? For experienced people it's often obvious what search terms to use and what to search for, but what if you're not familiar with the technology in the first place.
Don't get me wrong, I completely agree that people should do the background work properly before asking incomplete questions.
Especially I appreciate that you took time to explain the reason behind the downvote since it got me thinking about the threshold of answering a question at all.

Public Class BaseForm
Inherits System.Windows.Forms.Form
......
Friend WithEvents MnuBaseFile As System.Windows.Forms.MenuItem
Friend WithEvents MnuBaseWindow As System.Windows.Forms.MenuItem
Friend WithEvents MnuBaseFileExit As System.Windows.Forms.MenuItem
....
For Each fp In My.Forms.GetType.GetProperties
If fp.Name = "BaseForm" Then
For Each mnu As MenuItem In Me.Menu.MenuItems
Here I can get mnu.text = &File,
But mnu.Name = "", Nothing.
And I try to use the following block:
Dim fi As System.Reflection.FieldInfo() = bfType.GetFields(BindingFlags.NonPublic Or BindingFlags.Instance Or BindingFlags.DeclaredOnly)
For Each f As System.Reflection.FieldInfo In fi
If (f.FieldType.Name.ToString() = "MenuItem") Then
mnuNameStr = f.Name.Remove(0, 1)
End If
Now I can get field's name, but I can't use field to set text for the menu.
How can I get a field's name, the Menuitem's name, then set the text for the Menuitem?

|

Sorry ... I don't understand what you trying to achieve ...
Could you explain it once more (perhaps with an example) ?

I want to change the Text of a Menuitem dynamically in runtime. I can get a Menuitem in the
Menuitems collection, but it's Name property is empty.
For Each fp In My.Forms.GetType.GetProperties
If fp.Name = "BaseForm" Then
For Each mnu As MenuItem In Me.Menu.MenuItems
But in property window, the Menuitem has Name property, it's same as a name of field variable, like: MnuBaseFile

The Problem is that you ask the wrong question to the wrong partner.
As I understand :
MenuItem is a Control on your Form - which type has it ?
Why do you search inside the Forms.Properties ? You should search it inside the Form.Controls-Collection. I could specify it with more information from you.

Hello !
I'm creating a vb.net program that will use a sql server database. But for a lot's of record there's a document or image attached. I know that I can save the file on a folder and keep on database only the file path.
But I've read something about FileStream storage in Sql server 2008 , or the possibility to save an entire file on a Varbinary(MAX) filed.
So I'm asking if is a good idea to save files inside the database ?
Thank you !
