I am trying to save details from my program into a sort of mini database using excel, my program isnt having a problem opening the excel file, it is having trouble inputting the data. The first problem i would like help with is maybe a loop of some sort to get my program to look through each line on my excel spreadsheet and find the next empty line so it can input the data.
I was having some help from another person who gave me some code which go's to the very bottom cell and goes up until it finds text and then off sets by 1. However this was in the form of a macro, and I need a way to do it from my program.
Trying to use date selected in MonthCalender function to populate next empty row in an Excel worksheet. So far have tried: Private Sub DateSelected(ByVal sender As Object, ByVal e
As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateSelected
[code]...
But none work. How tried looping through a range ("B:B") but it ends up in an open loop. How do you stop it?

I have a list of files to read and have to append them all to one unique file. the problem is that when i open the first file to read. I read the first line and discard it. when i read the second line, its empty, but it is not in the original file. what im doing wrong? [Code]
I have an insert statement which works fine but before the record is saved I want to validate the text boxes. So I just need to know how to check for empty text boxes before the save button is clicked on. I have seen a couple of examples like:
Dim ctr As TextBox If ctr.Text = vbNullString Then MsgBox("empty box")
I've got a Program and a text file, this text file gets load into the list box but that's not the problem. The problem is that when I make the text file it makes a open line and this line gets loaded into the list box and I don't want empty items.
So here's code that I use to make text file Public MySettingfile As String = My.Application.Info.DirectoryPath & "Process History.MemFreo" Dim myCoolWriter As New IO.StreamWriter(MySettingfile, True, System.Text.Encoding.Default) myCoolWriter.WriteLine() myCoolWriter.Close()

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
How to apply for loop on grid view and to check the empty cell value then show a message... Dim cnt As New DataSet1.LibraryDataTable For i As Integer = 0 To cnt.Rows.Count - 1 For j As Integer = 0 To 5 If GridView1.Rows(i).Cells(j).Text = Nothing Then GoTo e ElseIf GridView1.Rows(i).Cells(j).ID Then GoTo a End If Next Next e: lblmsg.Text = "he is not return a book" a: lblmsg.Text = "he is return all book"
I have a richtextbox which has CSV values in each line. Whenever a line is inserted, after pressing a command button the program lets the user know how many categories each line has.
Example: Line1: a,b,c,d,e Line2: x,y,z
Pressing the command button would say: Line1: 6 categories, Line2: 3 categories. This works fine, except from when I want a line to NOT contain any categories.
[Code]...
I understand that VB recognizes the vbCrlf on Line2 as a char, hence a 'category', hence the line is not empty. But what happens when I want to consider a line as empty (ie Line2:0 categories)? Should I go with something like if txt.line(i).text = vbcrlf then...? This solution seems kind of like bypassing the problem instead of actually solving it.. Or maybe it's just me?
I'am new in the VB world, and should translate excel sheets into new sheets.I'am using Visual Studio 2008 (with VB .net I think) and I'am trying to tackle empty rows deletion.Maybe an additional problem is, that some columns having a space (visualy the row is empty and should be deleted).[code]...
Using OleDbDataReader, how does one determine if the Excel workbook is empty? BTW, OleDbDataReader.HasRows seems to always be True even for a workbook with no data.
I am using Outlook 2003, VB 2008 and Win XP.I am storing user ID's in the User1 field of the Outlook Address Book. This is working find I want to Find all Address Book items with a value in User1 [code]This will find an Address Book item, even if the User1 field is not blank. When I debug, the first entry found has OlContactItem.User1 = Nothing.If I set User1 to a value (for example Id # is 1234, so I set User1 = "1234"), I can find just the one Address Book item with:[code]How can I find just the Address Book Items with User1 is blank?
My requirement is to read all rows of an excel-sheet in first column that are not empty, are numeric and have a length between 15 and 20.
For example: 358218033354974 359473035499561 358218036156129 354022038366247 358218032490035 359473030516492 353210040325399
This column might have a header that is not numeric and there might be empty rows. This would cause an exception when importing them via SqlBulkCopy. So i want to prefilter the correct rows via OleDbCommand.
What I have tried so far is following(C# is also appreciated): Using connection As New OleDbConnection(sExcelConnectionString) connection.Open() Dim schemaTable As DataTable = _ connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _ New Object() {Nothing, Nothing, Nothing, "TABLE"}) [Code] .....
But this throws an exception if there are empty rows or the format of the value is incorrect. So my question is: How to restrict the rows of OleDbCommand to: Get only first column of every worksheet All values that are numeric Skip empty values Ideally only the values with a length between 15 and 20
Any way how to skip the empty rows, Or do I have to to select the whole datatable? I hoped it would be possible to do that only with one query because of performance reasons.
I'm writing a VB.NET program (VS 2005) that reads data from an XML document and writes it into a column in an excel spreadsheet. It's working fine, except for the following: after the first run, all the data appears as expected - for example
I am trying to write a code for excel so that it generates results in the last empty column on the sheet. below is a sample data of what is there:[code]

Im trying and failing to do the following: I have 90 textboxes named N1, N2, N3, N4 etc. I am generating a random number from 1 to 90 on the press of a button. If 1 is the number randomly generated then i would like the textbox N1 to to change its behaviour for example change background color. Apart from a Massseeeeeev if statement is there no way to loop through all these textboxes until the number generated matched the number in the name of the textbox? In VB 6 i used a control array so N(1), N(2), etc.
I'm using visual studios 2008, VB9 and I am trying to write an app that basically performs calculations on a set of data input by a user. During the calculations, I want to display the data at each step, and have it retained in the display area on the GUI (not overwritten by the next data being displayed).
For example:
UserInput = 1 Do UserInput += 1
[Code]....
I tried this, and other loop structures and can't seem to get things right. The actual app is a bit more sophisticated, but the example serves well for logical purposes.
I have a VBS script that allows me to do a recursive search through a specific registry key to find a key value in multiple of the key directories. And unfortunately it dosn't want to work properly with vb.net in my visual studio even when i try to make the syntax changes
