I am importing data from an Excel spreadsheet into an array. I want to search the array to find the location of each "cell" with text that contains a certain string (e.g. "MyTestString"). So far the best I can do is loop through each element and test it using CStr, but the code takes too long to execute (please assume all variables are properly declared):
[Code]...
(1) Is there a better way than looping through each element, such as a built-in function or a lambda that will return an array containing *the location of* all string matches?
(2) Would it be faster to convert the Object array to a String array rather than using CStr on each element? If so, what is the fastest way to convert a 2-dimensional Object array to a String array?
I've considered using Excel's Find function instead, but would prefer to limit the number of Interop calls to Excel.
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.

The Goal when complete is to compare Sheet 1 to Sheet 2 Then the Difference Recorded on Sheet 3 as a complete row with a date Stamp in A . If it is just a change then it is color coated Orange. If total new entry that was not on the sheet then it would be green If a Row is deleted in would be Pink.

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.
i 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

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()

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.

This might seem a ridiculous question but I just want to make 100% sure before I start committing any funds to software purchases. Can I use VB2008to develop automation routines to control Office2010 applications or must I absolutely use VB2010 to do so?I ask this because I installed an Office 2010 pro on my station which already has VB2008 and I do not have any Word14 reference in the COM section of the list of references...

I have set the identity impersonate to true in web config. This should be mostly an access rights issue.I have even provided access rights for the "everyone " user in the excel file and as well for the interop component. Please post ur valuable comments.
I have used VB.NET and Microsoft Offices Interop to create an application that will run on a server and will print files for different users.My problem is that I need to find a way to impersonate different users so that when MS Word opens and prints, the resulting print job is recorded under that user. I found this link that lets you run .net code as a different user - unfortunately it doesn't work with this code. The username recorded is still the user that is logged on the server.Code Removed by moderator. Any ideas how I can make the Office app I'm automating run under a different user to the .net program that is calling it?
