VS 2005 Append Data To Existing Worksheet?
Mar 5, 2011
I have worked out all the other bugs in my Staffing app. A while back .paul helped me with exporting my data to excel. So what I need to do now is this:
Schedule AM RN's and export to excel DONE
Schedule PM RN's and export to excel appending to existing worksheet
Schedule AM NT's and export to excel appending to existing worksheet
Schedule PM NT's and export to excel appending to existing worksheet
Schedule AM WC's and export to excel appending to existing worksheet
Schedule PM WC's and export to excel appending to existing worksheet
I only need 1 workbook, and each new full schedule will be a new worksheet with the beginning date/ending date as the worksheet name.

With the following code I can import comma delimited data from a text file into Excel.The problem is that I cannot seem to figure out how to append the data from the text file to an existing Excel file. (adding to a new row each time.)
With objExcel

.Workbooks.OpenText(Filename:="c:scripts1New Text Document.txt", StartRow:=1, Tab:=True,

am trying to load data from an excel worksheet & its really giving me headache. A particular column contains both string and numeric data. its picking only the numeric data & loading the string data as blank entries. I tried checking what may be wrong, i think i saw a documentation that says Excel scans the first 8 rows of a column & determines it data type.plz, how can i load everything on the sheet (i can get everything as string, but i dont want to lose any entry)

I'm trying to make a calendar in vb.net and I have come across this problem. I want to append some text into an existing datatable row. When I watch my debugger it says:"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.".

For x = 0 To 6

VB2005. I have several DataSets that I create or grab from an external source. One example is
Dim sql As String = "SELECT TOP 30 * FROM myTable" & vbCrLf & _
"WHERE Area='YY' AND CarNum='734EP' " & _
"ORDER BY ProcDate ASC;"
Dim da As New OleDbDataAdapter(sql, myOLEDBconn)
'create a dataset and fill it with the returned data.
Dim ds As New DataSet
da.Fill(ds, "MyData")
Once I have these DataSets I then have to pump them into a specific worksheet in an existing Excel2007 workbook. The connection and interaction with Excel and the workbook/worksheet is already established and that works. But I am stuck in exporting the DataSets
into the specific worksheet.
Note that I have already scoured the web and MS Community site and all code that I have found so far iterates through each and every row and column of the DataSet and then adds that to the worksheet in a cell by cell manner. This is fine and in testing that works. But there has got to be a better way to do this. For even a moderate sized DataSet the exporting just takes a long time. 25 records with 15 columns takes about 10 to 15 seconds.
I've also been experimenting with some scratch code I found that converts the DataSet to an ADODB Recordset and then uses the xlwksht.Cells.CopyFromRecordset function to export it in one fell swoop. I haven't got this one to work just right but it seems in the end it also does an iteration through each and every record and field to convert to the ADODB recordset.

I am reading an excel file. When everything passes the edits, it is then written to a database. However, if any cell in the row fails an edit, I would like to write a new worksheet (called Errors) containing all of the information from the row which failed.

I'm trying to use something simple this:
Dim Names() As String = {"Bob", "Bill", "Jim"}
Dim AllNames As String
For Each Name As String In Names
AllNames &= Names & " "
Next
Operator '&' is not defined for types '1-dimensional array of String' and 'String'
I guess I'm not trying to store each item in the string array correctly. How would I do this?

I am writing a program that will read and write to a file using the My.Computer.Filesystem namespace, and when I append my data file with the code shown below under SaveFile subroutine, it sometimes places extra ControlChars.Newline at the end of the appended text. Sometimes it places one extra newline, and sometimes it adds 3-6 newlines. I have tried everything I can think of to make it add just one newline at the end of each append, as I will be using the newline char to flag each entry on retrieval. I am working out some algorithms in this project to use in a project that will keep track of data in a file using csv format(just practicing saving/retrieving data from a file). The extra newline characters that are added will become a problem when I start to sort the data to display. my xSaveButton click event:
Private Sub xSaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xSaveButton.Click
Dim boolAppendData As Boolean

I have two RichTextBoxes, each of which can have any sort of formatting. I need to be able to take the rich text from box 2, complete with formatting, and add it to the end of box 1, preserving the formatting of both box 1 and the appended rich text.
I've not managed to find anything usefull on this anywhere apart from hints pointing to manually re-building the RTF codes for the result (but no actual VB / C# / C code to perform this or similar).
