I'm using Excel 2016 to access a DDE server (Rockwell Software's RSLinx Classic.) The DDE server is working correctly/can be accessed from other applications. The problem is trying to access it from Excel.
This is what is in my cell: =RSLinx|PS9TOPIC1!'N7:0'
The PS9TPIC1 topic is set up (and works) in RSLinx. RSLinx is up and running. But I get:
Remote data not accessible... Start application RSLINX.EXE?
Clicking Yes gets:
Cannot run 'RSLINX.EXE'. The program or one of its components is missing or corrupted
The program runs fine. I have ensured that RSLinx.exe is on the PATH (Double-checked the PATH for the running Excel using Task Manager.) It doesn't matter whether I have RSLinx running before starting Excel or have Excel try to launch it.
No, the option to "Ignore other applications that use Dynamic Data Exchange" is not checked for this document.
I tried running both RSLinx and Excel as "Administrator" with the same result.
Bringing up the help for data connections shows this:
Note: In an earlier version of Excel, you might have used Dynamic Data Exchange (DDE) in combination with the Step-by-Step Mail Merge Wizard in Word. Excel no longer supports DDE. If you'd like us to consider this feature for the next version of Excel, drop us a comment in the Excel Suggestion Box.
Try using an older Excel license.
I had the same problem, i already solved it. Just go to your project in the kepserver, open properties, and make sure enable the DDE conection to your server... Just that in my case. Good luck..

I have a few SAS programs that I need to run from excel. The programs pull tables from SQL, perfom some calculations and give an output table that I would like to present in Excel. So I figured that it would be great to run everything in excel.
There are a few parameters in the code that need to be changed before running, so the best idea I had is to put the SAS scripts in cells on an excel sheet and change the variables with VBA.
My question is, is this achievable? Can I connect to SAS and do everything from excel?
I'm fairly good with VBA, starting to learn SAS, but I don't really know how to connect the two. Thank you for your help!
Yes it is possible , i did this in my work a week ago , SAS have an documentation here?
The link below can help you.
http://documentation.sas.com/api/docsets/itechwcdg/9.4/content/itechwcdg.pdf?locale=en
You can use ADODB to connect to , see here for the strings
https://www.connectionstrings.com/sas/
Your options are:
1) use VBA to connect to IOM, create a workspace, run your program.
This requires quite a bit of VBA, as well as the SAS Addin for MSO, and various components.
2) Run a Stored Process (STP) via point and click using the MSO addin
Again, this requires a desktop SAS Addin deployment, and isn't scriptable with VBA
3) Run a Stored Process as a web query
This is an excellent option - you don't need any special desktop installation, you can easily add (url) parameters, you can use it with / without VBA, and your output will render easily into your worksheet so long as you stream tab delimited data via the _webout fileref (without %stpxxx macros). It will also work with all versions of excel and SAS.
This approach is described here: https://www.rawsas.com/sas-as-a-service-an-easy-way-to-get-sas-into-excel-power-bi-and-000s-of-other-tools-languages/
I have a system with an Excel spreadsheet template file which is used for invoicing. I would like the user to be able to click a button on an Xpage, which will then open the spreadsheet and enter the latest invoicing data in Excel. I don't mind if Excel is either the application on their machine or on the server, but my preference would be the application locally on their machine.
I've looked into Xagents, as I feel this is probably the answer. I know they can be used to create Excel but I have not been able to locate any mention of opening an Excel file, and entering data into specific cells.
Is this possible?
EDIT: you can use Apache POI for editing and creating Microsoft Office documents. This is a java project which gives you a handle to office documents and this can be used using java.
A good starting point can be the blog of Christian Guedemann from webgate:

The only way I KNOW and tried to write data from Notes to Excel is exporting the data to an HTML page and setting the Content Type accordingly (e. g. as described here (there are a lot more resources available for taht):
http://www.dominoguru.com/pages/developer2010_xpagexlsexport.html
I am not sure if this is of help but it seems that this project can help you:
http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=ZK%20Spreadsheet%20for%20XPages
As far as I can see this project can load Excel files from XPages - and then it should also be possible to edit the files.
Besides that the only solution I can think of is a Notes Agent that is called from the XPage. This agent can then run in background and do all the excel stuff. After running, the XPage can show a link to the Excel file. Actually this is the solution I would consider to implement - but maybe others step in with better answers here.
You don't want to introduce a dependency on Excel in your application -- wouldn't work with an iPad front-end. Rather have a look at the ZK Spreadsheet, it will fulfill your needs.
However if you have to have Excel, then you need a roundtrip solution: load the Excel from an URL (probably generated by an XAgent (?) and save it back. The saving back part is the tricky one. Normal HTTP doesn't allow that. What you need there is a webDAV capable server. Watch out for a project on OpenNTF soon (just clearing IBM legal) that provides webDAV.
However the ZK Spreadsheet looks much better for your needs.
I have a sample database at the following URL --> http://www.nnsu.com/nnsusite.nsf/%24%24OpenDominoDocument.xsp?documentId=B65507CB2DE15B3286257986005F061D&action=openDocument
Download the APCC.nsf. This will allow you to create/read a new EXCEL spreadsheet and then stream the resulting file to the requesting browser. There is not need to have EXCEL or office installed on the Server.
THe examples create a new workbook, but you can also store a "template" on the server or in a notes document and use it as a starting point and then save it to a document or stream it to the requesting browser.
With Apache POI you can read/write to a spreadsheet using data from the notes document the process is initiated from.
I have an SSIS (super)package that consists of several (about) 40 packages, each of which has several data flow tasks, most of them loading some excel data to a sqlserver database. So I have several excel source connection managers, one per excel file.
This has always worked fine until recently : I have to change an excel source in one of my packages (a column was added in the excel which has to be loaded in the destination sqlserver table) but I cannot edit the excel source in SSIS : when I click on "columns" I get an error box "DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER". So this is a design time issue, not a run time problem. I've seen a question like this one on stackoverflow but no answer. Anyone has an idea ?
I' ve already removed office 2007 and reinstalled office 2003 on my machine, but this didn't help
it has nothing to do with 64bit mode, which I've read about here
Is there some limit on the number of connection managers in ssis ?
Most of my connection managers were created with copy/paste and hence they have the same Id, although they point to different excel files. Could this be a problem ?
I should also mention that the package runs without any problems, so it's only "editing/changing" the package that doesn't work. For the moment I circumvent this problem by disabling the data flow that should change and by replacing it with a sql statement that hardcoded inserts the data from the excel into the destination table.
Maybe another intersting thing to mention : I can create a new package and add and change excel sources without problems, but then again, when I try to copy this excel source in my package, I cannot edit it.
Did you try to check the advanced options on the Source Connection?
Right click on the component and select "Show Advanced Editor..."
Select the column mappings tab and press the Refresh button.
This should point out that the XLS connection has some additional columns or that the file that you are pointing at, cannot be pre-validated at runtime.
M.
I'm not sure if this will work but try the Work Offline option in the SSIS menu in BIDS/VS. What this should do is not validate the connection before you edit the component. It might be able to get you into the component.
My employer is considering installing OpenOffice.org's suite of Office products instead of using Microsoft Office. I've written several advanced applications in Access and Excel, and I'm trying to figure out what will and will not be compatable with OpenOffice.org.
Specifically, what do I need to do to have Calc (OpenOffice.org's version of Excel) read and execute VBA in macro's and tie macro events to button clicks?
Also of note, I'm using the MySQL Connector from within Excel to dynamically update data in the spreadsheet. What might I need to do to preserve data connectivity to our MySQL server?
Thanks
As far as I know, OOo Base can connect to an mdb file to the extent that it can open tables and queries. I think anything else - forms, reqportes, macros VBA and native - would need to be redeveloped.
I don't believe that OOo Calc can read or execute VBA: it has its own dialect of Basic, which has a variant syntax. It doesn't, as far as I can tell, support the concept of Class, for example. Some work appears to be occurring, however, see the OpenOffice Wiki for more information. Right now, I'd say you should be planning on a careful and complete rewrite.
Regarding the MySQL connector - I'd say that's the least of your worries...
On the plus side, you're likely to have real job security for a year or two while you get everything ported!
I recently discoverd go-oo which seems to be able to achieve your task.
I am stuck with a problem
The Requirement is that, there a complex Excel file(XLS) that is used as template; it has Macros and all the worksheets are either locked or hidden. When the user clicks to download it, the follows operation occurs
Unlock a particular worksheet, fill some data # certain cells and then lock it back.
Unhide a worksheet, fill some data # certain cells and then hide it back.
I think there are two options to resolve it (if there are more then please let me know)
Interop libraries / Excel Object Library
OLEDb Driver
I cannot got with the option 1 as excel is not installed on the webserver and I heard that it's not a good option to install MSOffice # webserver.
My question is that can we use OLDb to perform the operations mentioned above OR is there any other option ???
BTW Sharepoint service is also not available :(
Please help!!!!
You could maybe try ExcelPackge.

Check out this question I asked some time ago for an overview of options. I ended up going with the Aspose library, which I link to in my original post. It's not cheap, but it does the job very simply and elegantly. It even has templating functionality built in (called SmartMarkers, IIRC).
SpreadsheetGear for .NET will handle this and has an API which is very similar to Excel. You can see what our customers say and download the free, fully functional evalution here.
