Is anyone familiar with a library or tool that can determine which format an excel file is in? Or, failing that, documentation on the different formats that would allow me to write my own?
I have a client who wants to be able to embed an Excel document (one that is currently sitting on the same server as the HTML document) like how you would embed a Flash app on a page.
I'm correct in assuming this is not possible, right? Please confirm/deny so we can hopefully move on from this because he seems to think this is possible. We are on a LAMP setup so no .NET tricks, unfortunately.
When one "Fills right in excel" , the Column name updates
eg.
1st cell
is
=A2
If I fill right the next cell will be =B2
But rather than the column incrementing I want to increment the row number
so 1st cell is
=A2
The cell on its right is
=A3
how do i do that?

I want to validate pasted dates to remove /'s and ensure the year is 4 digits and when users paste them in it overwrites my excel validation.
So, If a user pastes 05/19/10 into a cell, I would like it to convert to 05192010 or at least give an error if this is not possible.
I don't know enough VB to add sheet-wide code that does this and I'm not sure if it would work when users paste multiple cells at a time.
Hi.
I have an Excel file with one column which is filled with numbers. I would like to be read the numbers from this column into an array in C#. How can I do that?
Thank you all.
Several people have asked, in a roundabout way, but I have yet to see a workable solution. Is there any way to open an excel file from directly memory (like a byte[]) ? Likewise is there a way to write a file directly to memory? I am looking for solutions that will not involve the hard disk or juggling temporary files. Thanks in advance for any suggestions.
I have an Excel worksheet where the user enters certain data, which I want to store in a text file and upload to a server using FTP. One site suggested adding a reference to "Microsoft Internet Transfer Control" and then define an "Inet" object to do the FTP. However, I am unable to find a reference with this name in "Tools - References" in the VB Editor. Does anyone know of a solution for this problem? Thanks in advance.

is there any simple way to replace an image inside word-document with an excel chart using VB and preserving all of the format details such as image frame style, text wrap, anchor, etc. (thus the image is just a placeholder in a template document)
Hello,
I'm working with an HTML table, that contains numbers (formated) and when I export this to xls file (just change extension... hehe) I loss some of the formated data.
Example:
in html I have " 1,000.00 | 500.00 | 20.00 "
and in excel it shows like:
"1,000.00 | 500 | 20"
I want it to know if it is possible to show the very same format as in html.
THankyou :P
I have a Gridview in my ASP.NET C# Page. It has a couple of columns and also one image column. I can export the entire columns to an Excel file, but the image column is blank. By the way, I use the full path.
Any Idea?
Hi, I'm using VSTO, C#, and Excel but VBA probably applies here as well.
What's the difference between calling the Merge(missing) method on a range and setting the MergeCells property to true? Does Merge() fail more often? Thanks!
Hey Guys
I'm reading an excel file with C# and OleDB (12.0). There I have to specify the select statement with the name of the sheet I wish to read ([Sheet1$]).
this.dataAdapter =
new OleDbDataAdapter("SELECT * FROM [Sheet1$]", connectionString);
Is it possible to select the first sheet, no matter what name?
Thank you.
Hi,
I need to create some reports from a sql server database for end users to view.
Is it possible to hook into sql server from excel?
Update
The end user will only click on the file to view the reports, asking them to do more is too much to ask!
Hi, I would like to insert Date value to excel file using Open XML.
Here is my code sample.
cell.CellValue = new CellValue(value.ToString());
cell.DataType = new EnumValue<CellValues>(CellValues.Date);
Anyone know of some code out there that does this already? I have a bunch of pages with data grids on them in an admin website they want to export them to Excel, was hoping someone had this written already - or if not I'll post mine when I am done.
I have used the connection string below but I am getting an error when trying to create a table
Dim ConnString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFName + _
";Extended Properties=""Excel 12.0 Xml;HDR=YES;IMEX=1"""
Cannot modify the design of table 'tablename'. It is in a read-only database.
Is there an easy way to update the data source for multiple pivot tables on a single Excel sheet at the same time?
All of the pivot tables reference the same named range, but I need to create a second worksheet that has the same pivot tables, but accessing a different named range.
Ideally I would like to be able to do some kind of search and replace operation (like you can do on formulae), rather than updating each individual pivot table by hand.
Any suggestions?
Hi,
I've got some excel files, that were exported from tables in Access, and I want to import them into sql express 2005.
I need a script that will convert nvarchar(255) columns to varchar(255) and preserve links, when importing the data into sql express.
Thanks
