Office Automation :: Find A Text In An Excel Range Using VB 2008?
May 12, 2010
In VBA I am able to search a text in an excel range like this:
Code:
Workbooks("Book1").Activate
With Worksheets(1).Range("C1:C10000")
[code].....
I have upgraded to Visual Studio because of the jobs I am to carry out. So I am translating all the codes from "VBA" to "VB.NET" (Visual Basic 2008)But I haven't been able to use "Find Method" in VB.NET. I am using Microsoft Office XP Standart Edition (2002 Version). I downloaded and installed Office XP PIAs. After that I referenced them in my project. I used the code Code:Imports Microsoft.Office.Interop.ExcelBut I can't do what I want Now, how can I use "Find Method" in Visual Basic 2008 to find a text in an excel range in one of my workbooks?

I want to define a range in Excel, but I do NOT want to use "A" or "D" references for columns. I am making a table, and to set it's range I use:
Code:
.Range("A1:D4")
However, at the time i write the code I do not know how many columns will be involved, so I don't know if "D" is the end column. For rows this is fine, as i could write this:
Code:
.Range("A" & i & ":D" & j)
But how do I do this for columns? I really would rather not have to convert my integer number for the end column to text. If I know that the table should go from row 1 to 5 and column 1 to 10, how to I select this range?

I have formulas in certain cells and happens to be part of the Excel range that I pull into a vb.net array and when I write the array back out to the Excel Range, I loose all the formulas in it.Is there an option to retain formulas in a .net array?

is there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. 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?

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.

I am exporting text to a worksheet with fixed column widths and there instances where the text in the cell does not fit and will obviously overlap to the cell on the right.
I'd like to prevent that overlapping by reducing the font size of the cell if it is necessary. The problem is how to check if the text does not fit.

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?

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.

I have written an automation addin in Excel with C# (addin.dll). To use the addin, I need to 1. register it using "regasm /codebase c:...addin.dll"2. select in ExcelOptionsAddInsExcel AddinsAutomation the respective addin from the list
I would like to automatize 1) and 2), so that the user just needs to run an exe-file in order to use the addin. 1) should be no problem, but how can one automatize 2)?

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 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.
Code:
''' <summary>
''' Exports data from a datatable to excel.
''' </summary>

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.

I'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:
1) set a reference to the Microsoft Excel 12.0 Object Library
2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module
3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.

I am writing a program that loops through all of the sheets in an Excel workbook and saves each sheet as its own workbook. It turned out to be a bit trickier than I expected, since the Sheet.Copy method creates a strange object (see here for the MSDN discussion that I believe is relevant: [URL]. Anyway, I found a Stack Overflow post [URL] that got me to where I am, which is essentially complete, outside of one hanging EXCEL.EXE process that is left after the program completes, which I believe is a result of the sheet.copy method creating a new workbook (potentially a new application as well?). The other thing I run into, which I believe is related to this, is that even though I have my application set to visibility off, when I run the program, excel still opens up and is visible going through the steps.
Here is my code:
Code:
Imports System.Data
Imports System.IO
Imports Microsoft.Office.Interop
[CODE]...
Now I think the problem comes from the end of the loop, where I try to close the export file and the new worksheet it creates:
Code:
'close excel and release com objects
System.Runtime.InteropServices.Marshal.ReleaseComObject(exportsheet)
exportsheet = Nothing
xlApp1.Workbooks(fileNames(counter - 1)).Close(False)
I can't figure out what to do to release the `ComObject` for the new worksheet that is created. I have been trying all sorts of things, but it always throws a COM error when I do it and if I try to define it as nothing (like I do with exportsheet) is says that it is read only by default, so I can't do it. It seems like it should be something as simple as: System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp1.Workboo ks(fileNames(counter - 1))) But that is not the case. I have tried a few variants of this and I am thinking it has to do with the MSDN link above, but I can't quite sort out what to do. So the code works for my purposes, outside of leaving one EXCEL.EXE after it is done. As far as a test file, I am just using an Excel file with 3 sheets and I put some information on each and change the sheet name, so it is easy to see if it is working or not.

Dim xlWorkBook_new As Microsoft.Office.Interop.Excel.Workbook
Dim strOriginal As String
strOriginal = Server.MapPath(Request.ApplicationPath & "/Attachments/") & "abc.xls"
xlWorkBook_new = exlapp.Workbooks.Open(strOriginal)
The code hangs in the last line. It works fine in the development environment. i deployed in windows server 2000 ,where I get this issue. the browser goes half way and throws the below exception after some time

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.

We have a VB 2005 program that reads data from a database and builds an Excel output file to be emailed. This works fine from my computer but when we put it on the server it fails on the Excel functionality.
The error is: Unhandled Exception: System.Runtim.InteropServices.COMException
Although Excel is not installed on the server we did also build a Setup program to install our program. It copies the Microsoft.Office.Interop.Excell.dll to the server folder with the exe.I thought the setup program should register the Excel DLL and the program should work even if the server does not have Office or Excel installed.
