how I might check to see if a specific Excel Workbook (call it Test.xlsx) is open?I have a routine that calls a subroutine. Sometimes at the time of the call Test.xlsx is open, sometimes not. So when the subroutine runs, I need it to check first to see if Test.xlsx is open. If it isn't then the subroutine should open it and perform the subroutine's purpose operations. If it is open, it should not try to "re-open" it or worse open a copy of it; it should simply perform the subroutine's purpose operations.

I have been searching and trying for quite some time now but did not yet find the right way to solve my problem.Here is what I want to do:- open powerpoint with a file (an disable the UI of my app while it is opened)- make some changes to this file- save it with a new name- get notice when Powerpoint is closed (either by my app once the automatic changes are done or if the user quits Powerpoint)- enable UI once Powerpoint is closedThe notice is my problem. Is there an easy way (other than timers that check the process list) to get notice of when my started Powerpoint-Process is closed/quit?

That works perfect, however I have just noticed each day I have a number of winwords open (can only see them in task manager so they are hidden).

View 8 RepliesIt 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.
View 7 RepliesI have an application, running multiple threads, and in many of these threads, Outlook is being called, some mails read, attachments downloaded, and then the outlook instance closed. But it is possible that there are a number of threads trying to do the same thing at the same time. There is of course a lock at the beginning and end of the process, so that no two threads try to access the outlook application at the same time.
"Sometimes" i get an error message : Creating an instance of the COM component with CLSID {0006F03A-0000-0000-C000-000000000046} from the IClassFactory failed due to the following error: 80010108
I am using visual studio to create an application that opens an excel file and then for each entry in the first column the entry in the second column is stored in an array. Then excel opens two other workbooks and for each entry in the first column it searches for a match in these other two workbooks and stores the corresponding value in an array.
Anyway, the problem is closing excel afterwards. I have used the thread: [URL] to work through the basics of cleaning up. I used the cleanup code provided and added the WithEvents caveat. I do not have strict option on.
I believe the problem is the fact that I have three workbooks open.
This is my cleanup code: (wrkbk, wrkbk2, wrkbk3 are the workbooks; datasheet, datasheet2, datasheet 3 are the worksheets; excel is the application)
Code:
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
[Code]....
I got the impression that order was important in the cleanup procedure so I have tried some variations of moving the workbooks and worksheets around.

View 1 RepliesHow do I import data in Excel from a CSV file using C#?

I am writing a program to automatically recognize new data log files in a specific folder and proceed to process them in a routine I scripted. I have the program working fine for when I manually place files in there, but I know there will be an issue when my data logger is working because it will create files and then write to them for approximately 12 hours.[code]Which works fine, but how can I modify that or what should I use to force the program to wait until the file is done being modified? Say force it to wait at least 1 minute after the last modification?

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.
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.

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.
is there a way to extract all the text from a Word Document in VB.NET without actually openning the file? I'm asking since it is a very time and memory consuming operation to open a word document, select all, assign it to a variable and the close the file.I have a routine the opens all emails in a mailbox and analyses the body and subject object for regular expressions. I would like to do the same for the attachment, if it's in Word. if it's not possible to extract without openning the file, can anyone give me the best way to do it so that the routine doesn't destroy my server memorywise?
