Can I create a macro written in C# for Excel that allows me to export a cell's data to a SQL Server or Access database?
Basically, I'd like to create a button in Excel that saves the data in certain cells to a database. Can this be done?
Instead of creating a UI from scratch for a program, I've decided using Excel as the user environment would be better for business needs.
How to automate Excel by using Visual C# to fill or to obtain data in a range by using arrays would be a good starting point.
Be aware, you're going to find it frustrating to control what people attempt to enter into the Excel sheet, as the inherit flexibility of the data works again your efforts to write it to a database destination.

I am trying to make an application in VB6.0 using MS Excel as database. I have some textboxes on my VB Form to take input from user. I want to store those values in an Excel file. There will be another form where I want to retrieve the values from Excel and display it in textbox/labels.
Can I use SQL queries for inserting/retrieving the values while using Excel as database?
I just need a sample code for understanding the process. Rest I will try to manage.
Thanks in advance.
It's a poor idea.
While you can treat an Excel workbook as a data source via the Jet IISAM or ODBC Desktop Driver this is really meant for simple importing and exporting and has numerous limitations.
Save yourself some grief and just use Jet 4.0 to create and make use of MDB files. No MS Access is required, Jet 4.0 comes preinstalled and has for a rather long time now.
So I have been using ASP for all of a week now and perhaps this is something that I just can't do, but I am trying to dynamically generate reports from data stored in a SQL database. I am publishing the reports through an ASP document and displaying by specifying Excel for the MIME content type:
Response.Buffer = TRUE
Response.ContentType = "application/vnd.ms-excel"
Is it at all possible to "attach" macros to the document? I understand I can do basic formatting in the HTML, but I would prefer to import the desired database data and handle it within excel via macros.
EDIT:
I have several reports I need to generate but for one example:
I want to load retrieved data from the database into a sheet in excel.
Attach Macro
Begin Macro:
Hide the specified sheet.
Programatically create new sheets for categories of data.
Format sheets.
The question is not about how to program the macro, just whether or not a macro can be attached and how to achieve this. In regards to alerts upon opening the sheet, if I can attach macros I should, theoretically, be able to suppress those in the Open Workbook event.
EDIT: I believe I can achieve the desired result by using OWC (Office Web Components) (see http://support.microsoft.com/default.aspx?scid=kb;EN-US;288130). However, I am not sure if I will be able to install it on our Web Server. Any other suggestions?
While it is possible in a strictly technical sense, it is neither simple nor advisable. The recipient of the sheet will get multiple prompts related to the security of your macros; the source of your macros; and if they really, truly, honestly meant to click to enable macros...
I want to create Windows based inventory application. I need to automate the manual entry in multiple excel spreadsheets, and in spreadsheet formula's are also used . values in sheets are interdependent upon formulas.
I want to use excel like tables and formulas in application. Is there any way of creating spreadsheet and assigning formula's to cell ?
Or Any better alternative?
As Tony suggests using a databse is a far better idea. If you use a database then you can have excel sheets connect to this for other users to interact with.
Can you connect to sql server from Excel?
I am storing data in a backend database (PostgreSQL) which is running on a Linux machine. I want to be able to fetch data from the database, and populate a sheet in an excel workbook, so that I can carry out analysis in Excel.
It has been quite a while since I wrote anything in VBA, so I would appreciate some help (or links) in getting started. I would like to know the best way to approach this:
Pure VBA solution OR
Mixture of C# or other .Net language for data extraction logic and VBA for manipulating Excel objects (sheet data population etc)
Any ideas, tips, snippets and/or links that can help me get started on the twin objectives:
fetching data from a backend database (PostgreSQL) into Excel
populating a specified sheet in Excel with the columnar data retreived from the database
will be much appreciated.
If you are just trying to import data, Excel can do that without additional code. Just set up your windows client to connect to your postgreSQL server thru ODBC. (Here's one way guide to setting that part up: enter link description here
Then in Excel (Use a modern version, like 2007 or greater) from the "Data" tab, click on "Existing Connections" to connect to the ODBC connection you set up and pick the tables/data to import into excel. Once the spreadsheet has loaded the data, you can just click the "Refresh All" button to update the data.
I have a project in which I need to compare different versions of an Access 2003 database against each other. We're not interested in the data in the tables. We're only interested in the objects that describe the database. I.e. Form objects, Report objects, QueryDefs, TableDefs etc.. The databases are fairly large so the approach is to dump all the descriptions for objects of interest into a text file by running a VBA app in each of the databases and then comparing the results in a diff viewer.
I've been looking around for several days to find out how to dynamically dump access 2003 macro content from within VBA. Please don't confuse this with dumping VBA code from VBA.
I know about Application.CurrentDB.AllMacros to get a list of macros in the active access database. But I can't get at the macro object from Macro(MacroName).SomeProperty because the macro isn't open. So I've been trying to look for a way to open the macro and haven't found a way to accomplish this through VBA.
Any help on the topic would be appreciated.
Thanks!
You can export macros with the undocument Application.SaveAsText:
Application.SaveAsText acMacro ,"AutoKeys", "AutoKeys.txt"
...saves the AutoKeys macro to whatever the current directory is.
You could manually ask Access to convert the macros to VBA. There is an option for that, I think when you right click the macro. After that you can compare the generated VBA.
See the following page for a list of utilities to compare Access databases
