Office Automation :: Excel Automation - Cannot Use Office PIAs
Feb 14, 2009It appears that when one creates an instance of Excel, using CreateObject, (Late binding), the suggested Excel closing function (with GC.collect etc) does not work. I have tried several suggestions, and the only one that works is process.kill method. Do you see any problem in using this? BTW: the reason we are using late binding is that we cannot use Office PIAs....not sure which version of Office would be installed on the client site. We work with O2003, but the client might still be at 2000 or 2002.

Office Automation :: Copy Data From One Workbook To Another ?
Sep 3, 2009I'm trying to copy data from one workbook to another. The program first grab this data that comes in from a data collector and puts it in a excel spread sheet. It then closes its link to excel. I'm trying to grab that data out of the first spreadsheet and put it into a workbook thats set up like a template that will crunch the numbers. I'm currently dim-ing a varible called "grabber" as an Excel.range and setting it equal to the range of my raw data. Can I then say grabber.copy(Destination:=oWS.cells("A1")). I've been beating my head against a wall on this one.

Office Automation :: Excel 2003 Automation With VB 2005 Express?
Apr 20, 2010Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.
I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.
Office Automation :: Orphan Excel Process Started Via Automation
Jun 17, 2009I'm using excel via interop in application.Sometimes users kill application that created excel instance and that results in excel instance sitting in memory without any chance of disposing it.First I tried to tackle this using ROT(running object table) looks like not all instances of excel are registered there.Than I tried to somehow mark excel process after it is started via interop.[code]This works as long as excel is visible but in my case excel window is invisible.All I need is to somehow mark process that started via automation with the parent PID, so that later I can kill it if parent does not exist.

View 1 RepliesOffice Automation :: Multi-threaded Real-time Data Handling In Excel With COM
Jun 22, 2010I have an Excel based algo-trading app that needs to take in lots of real-time data, and make trading decisions based on the calculations driven by the data. It is not one of those "read-only" stock ticker kinda spreadsheets.I created a COM object with VB.NET that runs in its own thread space which collects data from a socket, and when the data is read it raises an Event with data attached. In Excel VBA, the event handler parses the data, puts them to the right places on the spreadsheet to feed calculations (so far it sounds like a stock ticker app), and then, based on the results of the various calculations it does something.The problem is that when the user starts to click around the spreadsheet while there is large amount of data coming, the event handler's cell updating breaks apart. If the app is left alone without user action, it stands well. My frustration comes from not understanding what happens to the main thread when a user clicks around. Either the event handler blocks the user action, or the user action blocks the event handler (under which case I will put in some queuing facility). But I just don't see how user action can break the code (like causing VBA to stop executing)

Office Automation :: Excel Automation Causing: Rpc_e_serverfault
Jun 1, 2010We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.
This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.
My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.
Office Automation :: MultiThreading In MS Office 2007 (Excel, Outlook, Etc)?
Mar 28, 2011i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type

Dim xlsApp As New Microsoft.Office.Interop.Excel.Application

Method SetRangeAllBorders does about the same as these other methods but my post is too long to add it. The only other things not shown in these code snippets are a few string variable that are defined in the class, studentWS, studentsWSPW, paymentsWS and paymentsWSPW My App creates an instance of the class, loads some data, runs the method above, and then sets the class to nothing.
