Office Automation :: Transferring Data From Excel To Access?

If value exists in table Then
Return the value.code (not the value but the code related to this value)
else

Create XSD And XML Document From Dataset - References Xsd Import Xml To Excel

Mar 16, 2012

I have read and googled a ton of xml documentation but haven't quite gotten an answer to what Im trying to do. I am trying to create an XSD document that generates explicit type definitions for fields in the dataset. I am then trying to create a sample XML document that validates against the XSD document.

This works fine inside of visual studio because I can read in the schema and the document and it validates BUT, the xml document created has no real reference to the XSD via xlmns or other method. If I want to use this xml data in say MS Excel and I try to import it doesn't know where the XSD is to validate against so it assumes it based on the values. Is there a way in my code to add the xlmns to both the XSD and XML if that is what is needed to solve this? [Code]

Office Automation :: VS 2008 Excel 07 Add-In Reference?

Aug 18, 2010

So I've been trying to write an Add-In for Excel for a week now. I already have the add-in made up in VBA (CustomUI.xml has been added too for a ribbon). I've been using it for awhile now from Excel's VBA Editor. But I want to get a bit more fancy with it, so I'm going to re-write it in VB.net since it's ribbon designer is nicer than writing XML code by hand. The only problem is, I've been very confused on how Visual Studio sets up all the references to Excel.As I've been looking through examples in threads across this forum I see a lot of people using this code to get access to Excel.

[Code]...

at the top of every sub routine that I'm going to be using excel in? Isn't that going to open a bunch of different windows and separate my code from the data I'm trying to manipulate?

Office Automation :: Excel Automation - Cannot Use Office PIAs

Feb 14, 2009

It 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 :: Multi-threaded Real-time Data Handling In Excel With COM

Jun 22, 2010

I 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 2003 Automation With VB 2005 Express?

Apr 20, 2010

Ok 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

I'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.

Office Automation :: Excel Automation Causing: Rpc_e_serverfault

Jun 1, 2010

We 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.

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

I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?

Office Automation :: Excel Process Continues Running (.Net Framework 3.5, VS.Net 2008, .Net 2008)

I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.

Office Automation :: .net Automation Excel App Not Closing

Sep 25, 2009

I'm having an issue where my excel.exe process doesn't close until I close my .net application. I'd like to avoid using Process.Kill() if at all possible.

Code:

Private Sub WriteRowsToXls(ByVal rows As DataRowCollection, ByVal xlsPath As String, ByVal showStatus As Boolean, Optional ByVal AddTotals As Boolean = True)
Dim xlsApp As New Microsoft.Office.Interop.Excel.Application

[CODE]............

This method references a couple of other methods I use for repeated formatting tasks, I'll include those methods below. (I added the FinalReleaseComObject into the other methods after reading Mike's thread but the issue persists)

Code:
Private Sub SetRangeValidation(ByVal rng As Range)
With rng.Validation
.Delete()

[CODE]..............

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.
