I have completed some code to open multiple workbooks and copy data into one master workbook. I can't figure out how the code "chooses" which workbook to open first to import. Anybody have any ideas what is the method excel uses to select the files?
Take a look at this post over here. There is a link in the responses to a blog which talks about Window natural sorting method. Unless you specify in the code which files to open, VBA will normally open the files based on the natural sorting method.

I need some conceptual help from those more experienced than me --
I know you guys usually like code but I have many pages of code on this project and my question is not regarding any code I have but rather how I might code something I have not been able to figure out.
So basically I have two workbooks whose main purpose is labor tracking. one is the control workbook that has all my code, the other is a workbook where reports are made by field workers. The reason the field workbook cannot have code is because it will be operated from an ipad which I believe cannot yet run VBA. I know how to establish the connections necessary, however for every project a new copy of both the workbooks need to be made. I already have functions that clear out, reset and save the main workbook however I am struggling with the connected workbook. I know how to save the connected workbook, but I was hoping to preserve the connections between the two old workbooks when I run the macro that saves them as and also mirror those connections between the new workbooks. Is this possible or will I need clear all connections and re establish them every time a new set of job books needs to be created?
===> EDIT: I believe that I need to embed the report book into the main book, but that still begs the question on how I save the embedded workbook as at the same time I save the main workbook as in order to create a new book with all the same connections
Would like to check the value from my master file and copy the data comments from different excel files.
In my master I have a column contained all the user name. Would like to copy the address of the user from different excel file. Would like to open the workbook and look through is the user name in the workbook, if not then then exit and open another workbook.
How should I complete the flow ?
Unfortunately StackOverflow is not a free coding service. Our goal is to help you understand how your code works and engage the community with questions that will also help others in the future. Try running some of the code on your own and see what you can come up with. There are hundreds of sources online, one of my favorite being "Excel Easy", a website that breaks down VBA coding to its simplest form. Check it out and then after you've given it a go yourself feel free to ask any specific question about your code!
Trying to figure out the best way to kick off an excel macro at a certain time. I found a few suggestions, but I still have plenty of questions on the idea and was hoping you guys could provide some clarification.
What I am trying to do: I have live excel workbooks that are connected to my database. So at 11:30PM on the last day of every month I want to go into several excel workbooks (I have one for every vendor that we sell), enable the security and editing and refresh the connection so all of the information in the sheets is up to date. Lastly I would like to then save a copy of that file in a sub folder inside the current folder.
Run on time method:
Here is this run on time method that I found on ozgrid. My question is, I am assuming that excel would need to be running at the time in order to execute the method? If so what would be one way of opening up excel and refreshing a workbook to be saved?
Running excel on Windows Task Scheduler Windows Task Scheduler
Essentially this method is using an Excel Controller to run excel using VBS...Seems more promising than the run on time method but I am not very familiar with how an excel controller works or VBS, so any help or ideas on this one would be greatly appreciated.
Any input is greatly appreciated. If my ideas are way out in left field could you guys help point me in the right direction?
Thanks for all the help in advance!
Turn the problem around. Create a workbook with normal Excel query tools and have it load the result set of the query when the workbook is opened (You don't specify a version, but see Refresh an external data connection for Excel 2013).
Then, either create a view in the database that contains the results you require, or to materialise the result of a view into a staging table that is then read by the workbook.
Users can then open the workbook whenever they require data, and the current results will be available. A parametrised version of the query could then access a history table to older periods.
This way all data is only prepared when required, and is always available without the scheduling complexity.
I'm creating a program in VB.net that does the following:
At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file. (add in a row of data, format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
What I've thought of so far:
The way stated above. Import to excel -> format
Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
I really appreciate any advice/suggestions that anyone is willing to give.
You will want to use http://epplus.codeplex.com/
It allows you to create an Excel file from scratch, without having to start Excel itself. Automating Excel will make the process slow and it lacks robustness (Excel process can hang or not close properly).
In addition, using a .Net library allows you to run it on a server or so where no Excel is installed. (Next step would be to inspect the mailbox via POP, IMAP or the Exchange API, so that part doesn't have to be run on a client machine either)

You can also just use the Interops from MS to interact with Excel, Outlook, Word, etc. They're not difficult at all to use. I'm not familiar with CodePlex, so that may be a better route or an easier one. I just wanted to provide you with an alternative.
With Microsoft Office 2010 Interops you can not generate Office files from .net applications anymore.
You can manipulate data from existing Excel files so you need templates(your 4th point). Then Excel allows you to query some databases. You may be able to simulate one with your folder, otherwise I suggest to convert your .txt files into some databases. (3rd point)
If you do use an older version, you can crate your Excel files by loading them into an instance of Excel and manipulating them as you wish.
By the way I supposed your attached files would have some sort of format.
If you want to manipulate Excel files, I can recommand you the NPOI library found on CodePlex. It has several advantages over OLE-automation:
NPOI is not dependent on a specific Excel version.
Excel (or any other Office component) need not to be installed.
It is faster.
It works with both .XLS and .XLSX files.
We are using a third party software called excel writer. May not be what you are looking for becauseit needs to be license, but it is very fast and the clients does not have to wait for a chart or a data output. Because we have that tool, have not try anything else.
I have an excel file which is auto generated by third party software..and its readonly file and its data constantly keep changing online.
now i want to use or read that data in my vb.net application whenever its changes take place in excel file automatically.
please help me..
Cody's right. No question, but I'm guessing you're looking to do something along these lines.
First, you'll need to pull down a copy of that XLS file (sounds like it's online at a website somewhere). To do that, you'll need to perform a pretty normal HTTP get or use whatever API the website provides to pull the file down.
Save the file locally, then open it and read it using EXCEL AUTOMATION. Just google excel automation for loads of examples of opening a worksheet file, reading cell values, and closing the file.
There's other options too such as the OpenXML api from Microsoft to allow you to read the contents of XLSX files directly without using excel automation, so that may be a possibility. not enough in the original post to know which would work best for you.
