Importing Some Excel Functions Into VB?
Dec 23, 2011
how would it go to be able to use in a VB application some statistical functions that are in Excel?
Basically I would just want to know the general lines of how something like that goes, what things need to be imported and so and whether this is a very complicated thing or rather it is just about importing stuffs. I have found something like this (which extends itself ) . I get tons of error red lines that never seem to end despite correcting using the options, new ones appear etc

So I'm trying to import a function from a library I'm developing. I have "libraryD.dll" built for debugging and "library.dll" for release. Unfortunately, that means that I have to do this:
[Code]...
Now this would be fine but for ALL 40 functions this would make things very ugly to look at (and a tad bit unfriendly).I would like to do something more like this:

Is there ANY way to do this in VB?

1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.

This is in vb 2005, and I would like to be able to click a button (i.e. export to excel, import from excel) and do this.If you need any more information then just let me know.
1)How do you export the data that is displayed in a datagrid to Excel.
2)How do you import data from an excel file, and fill the datagrid with that information.

I am importing data from Excel to a datagrid in VB, I can get the data on there no problems and also save this back to a SQL database without any problems.
However I have a new spreadsheet which has the same product listed again and again with the same description but different totals, what I want to do is to upload this to the datagrid just once for each description, with a grand total of all the seperate totals

I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "
Private Sub Import()
[Code]...
After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.

I have been trying for several months (in my spare time) to write a vb.net (version 2010) program that connects to Excel (version 14) and imports numerical data.This data will be used later for engineering calculations.I have tried the Interop code which I have found on the internet with limited success and now I am trying the connection string method.I have found some examples of code, on the internet,that I have pieced together and can't get it to run.Below is that code.
Imports System.Data.OleDb
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code].......
This is a screen image of the error I get when trying to run the program.

I need to import data from Excel worksheet into the VB.Net program. First, I need to get the data to some array or arraylist and secondly to show the data to user through datagridview or similar.So far, I have this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=C:TempTest.xls ;" & "Extended Properties=Excel 8.0;"[code].....
How can I adjust the code to manage that? And how can I import the same range to variables (the range contains approx. 200 rows and 30 columns of data points) and I need the flexibility to add or delete items (rows) from the data in memory later.

Im having strange problems when importing data from an excel file into a sql table. Everything seems to imports ok until i look at the data in more detail, this is when I notice its imported the data but in the wrong order. for some reason when I look at the db table all records are in the wrong order, and strangely enough it seems to be a different order every time I import things. Is there a way to force the routine to import the data in the same order as the it is in the excel file?, because at the minute it seems to have a mind of its own.
My code is below:
Public Function ReadExcelFile(ByVal sFileName As String) As Boolean
Dim oSQL As New clsSQLHolder
Dim excelCon As String
[CODE]........................

I have a problem loading big spreadsheets into a datagridview.
I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.
How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.
The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...
see code:
[Code].....
My problem is that whenever there are values below the heading of the cell the datagrid displays (null)
No matter what i do even converting the values in excel to text it does not display the heading of that column.
When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

I'm attempting to import an excel spreadsheet into a dataset. The spreadsheet is selected by the user by browsing for a file. I can get it to work properly only if I know the exact sheet name, but it varies from sheet to sheet. I need to tell it to always use the first sheet in the workbook.
I've declared the following at the beginning of my project:

how to best go about this project. I have just been given the task of creating a program that will primarily be used to import and sum a excel or text file that is tab delimited. As a quick example the file would be in the following format:[URL]The problem is that I would need to store this information locally (unless you know better) because I need to be able to append information to this from a second (or third, fourth, etc...) file and re-sum it, lets say that this is the second excel file that I needed to sum:
[URL]
I would have to append the week5 and week6 columns and add the Neapolitan row to my summation. This program will then format the sums into a list of the different flavors and the sums of all products sold during the total weeks and output to a text file.I have informed my employer that it would be easiest to do this with a VB script in excel, however, they are adamant that they want this done in VB.NET with a GUI.

I found a few examples online on how to import excel into sql via vb. but can i do it via stored procedure?
Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D: esting.xls;HDR=YES',
'SELECT * FROM [SheetName$]')
So like, can I pass in:
('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D: esting.xls;HDR=YES',
'SELECT * FROM [SheetName$]')
As a parameter to SQL Server SP?

Currently I'm working on some code to modify a spreadsheet before it get's imported into SSIS, using a SSIS script task, so VB.Net.
However I'm having real trouble figuring out the correct code for doing a copy, paste as values for a particular range. In other words: my spreadsheet has formulas in it and I want to convert this to values before it gets imported. I have no trouble figuring out what it should be like in VBA, I just can't get it to work in VB.Net.
Does any one have a clue, or even better a code snippet on how to do this? I can find alll sorts of examples in VB.net for excel just no Copy- paste (as values) ones.
