I'm developing application in VB.NET 2008.I'm reading data from Excel through OledbConnection. Here data are reading sometimes perfectly but sometimes it is missing to read some data.
Example :In Excel ,I have 79 columns in excel and 4 rows , first 3 rows are headers so after import i'll delete that rows and actual data starts from 4, so here i have only one row.After Reading through oledb, that dataset's datatable has only first 3 rows( first row became header and 2 & 3 row only in datatable, its ignoring 4th row)

I'm a new VB programmer, although I have a decent background in java.Anyways, I'm learning VB and I'm trying to read data from an Excel file using VB 2008 and can't figure out how to accomplish this. I can't seem to get any data from the Excel spreadsheet to display in a simple Windows form. Also, there's a decent amount of data in the spreadsheet so I was wondering if it makes sense to just read data as needed from the excel spreadsheet or if there was some type of data structure that I could import the entire Excel spreadsheet into and do my analysis from there.

View 6 RepliesI am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
I have some trouble with opening a excel sheet and getting some data out of it.
I want my program to have a button, when pressed, gives a "select excel file" popup and then load the data from some cells into my sql database.
So, when opening a excel file the program should get the data from cell D3 to D8 and put that into the sql database.
I now have the following, but that will only open the excel file.

In my application I read data (using data binding) from an Excel spreadsheet into a DataGridView. This works, but the data columns contain text fields (strings). I would like to set the data type for some columns to "Date" and Decimal. I cant do this on the DataGridView (error: cant change properties for data-bound stuff) and I cant figure out how to do it on the dataset or data-table that I bind to the DataGridView.The following is the code I use to read and bind the data:
Using con As OleDbConnection = New OleDbConnection(cs)
'
'open the OleDbConnection
[code]....
The commented out code (below the 'Todo: comment) causes a additional table, but I want to change the table with the data.
I use an OLEDB connection to read from an excel database, and this loop to read in all of the data from each of the columns
While reader.Read()
For i As Integer = 0 To reader.FieldCount - 1
temp = reader(i).ToString + ControlChars.Tab
output_file.Write(temp)
[code]....
Some of the columns contain date information, which are read in fine (usually as a string "2/20/2011" or so), but the headers of those columns are read in as a blank "". The headers for all the other columns read in fine, but not for the date containing columns.
I am trying to read some data from an Excel 8.0 worksheet using OLEDB thusly:(Warning - contains curly braces)

The problem is that for some columns it sets the data type to be Double even though the spreadsheet column format is "Text" and teh column contains non-numeric data. Then when it gets to that cell it returns DBNull instead of the text value.
Im brand new programmer and started out with Visual Basic 2010. And Excel 2010. I will probably ask lots of dumb questions, but if I dont ask, I wont learn. I want to know if there is an easy way to transfer text from a VB app to Excel? I made a small program with a few textboxes, and a "Send" button. I have a textbox where I want to put the name of the projekt for example "projekt1" I want my values to go to the excel sheet in specifik cells and then the sheet be saved as "Projekt1" if I named it that.
Next time I open my app I want to load the values or make a new "projekt2" and it will be saved as "projekt2" I know u guys cant give me the code for this but if we take it small part. First, transfer values to Excel, How? Any tuturials on this somewhere.
I have drawn some lines into a picture box as per an engineering standard. I wish to do the following:
1) Transfer the contents to an excel spreadsheet.
2) Before transferring to excel, it would be nice to add texts at four different locations of the picture box. I have tried various solutions which I found on the net but they were not very successful. The main problem with most of the solutions is that they washed the contents of the picture box which I manged to drawn after considerable pains.
Do anyone know how to transfer the records from DataGridView to Excel.
