Using VB To Open A Spreadsheet Call "DTNPrice" Within An Excel Worksheet?

Sep 17, 2009

Open A Word Document Or An Excel Spreadsheet From Within Separate VB App?

Mar 15, 2011

I have posted this in other parts of the forum but either im not understanding what they are saying or they arent understanding my question.My goal is to open a word document or an excel spreadsheet from within my seperate VB app. bounce some of my calculated variables and images out to specific markers in that document, and then print the document.

I can Open my office doc, I can send the test variables out the way they need to go out. I cannot get an image to go out to th open document from within my vb app.I feel like it is something relatively dumb in my code but i cannot figure it out.

[Code]...

The issue i have with that line is that even though i have made a picture object in my excel sheet called Picture1 it is not public and i cannot access any of its members to modify it.

OleDbException Saying Spreadsheet Is Full When Inserting To Excel Spreadsheet

Nov 11, 2011

I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).

For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.

I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.

To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):

Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""

Merge Multiple Excel Files Into One Excel File And It Works For 3 Source Files But Its Not Working If Workbook With Worksheet Count Is > 3?

Aug 18, 2011

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.

Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

Office Automation :: Call A Spreadsheet Dependent On The Day Of The Week?

Sep 16, 2011

I have a slight problem , using vb 2008 i have written some code that checks the current datetime on the computer. This gives me the answer in the format mon, tues etc. what i now want to do is to use that to call a spreadsheet dependent on the day of the week. here is my code so far

Code:
Dim TIME As DateTime = DateTime.Now
Dim FORMAT As String = " ddd "
TextBox1.Text = TIME.ToString(FORMAT)

[Code]....

Now i have tried the private sub eg SATS() on a separate button and it works perfectly . so it appears to be that the sub is not been called. I think it is probably a syntax where the datetime answer is not been recognised, in that textbox1.text = "sat" is not the same as datetime = sat .

Excel Worksheet Interaction With VB?

Apr 15, 2008

I would like to prompt the user, in the middle of a VB program, either with MsgBox or any other dialog, to input data in a worksheet of the Workbook that contains the code and then, on some event, read the data and continue execution. I was not successful with MsgBox (and other forms) since it is modal. The user cannot get focus on the worksheet, input data and then continue execution by clicking a command button.

Getting Incorrect Excel Worksheet Names In .net?

My application searches for a specific worksheet in an open workbook. The code to find the worksheet is:

If Amendaction = True Then
If oBook IsNot Nothing Then

For Each ws As Excel.Worksheet In oBook.Sheets

If ws.Name = SheetToFetch Then
SheetFind = ws.Name

When I execute the code, depending on the worksheet name, the result found in ws.name has one or more spaces in front of the text. e.g. "Bour001" used in creating the worksheet name becomes " Bour001" when returned by ws.name.

Import An Excel WorkSheet Into A Datatable?

May 13, 2010

I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.

I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db.
