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.
Edit by Moderator: [URL]...I know this thread is extremely old but it applies to my situation.Using Visual Studio 2008, VB, I get an error in this code:
Code: Dim strWorkbkName As String Dim strWorkshtName As String Dim XlApp As Object Set XlApp = GetObject(, "Excel.application")

I'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.
I have 2 sheets in a workbook that have links on them. I need to copy both sheets into this new workbook at the same time to update the links and not have sheets looking for the original workbook (it just temporary and deleted after the copy). I thought I had it, but I cannot figure out how to deal with the array that is needed (I copied the code from macro builder in excel)..
I have a seemingly simple question I can't seem to figure out. I have an old VBA application that connects to a database using OLEDB, grabs data, and populates an excel sheet using Excel.QueryTable after the user clicks a button. I'm trying to port this rather large program to VB.NET. I've created a few projects in my solution, one of which being an ExcelWorkBook. I want this workbook to load each time users launch the program and be blank until they click a button which will populate the data.
Dim exlapp As New Microsoft.Office.Interop.Excel.Application 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.
I have got problem, I got function which should correctly check if Woorkbook is open or not, but anyway if i got open my excel file or not I always get False Value in MsgBox. I don't know where is a problem. Please check it:
Imports Excel = Microsoft.Office.Interop.Excel Public Class Form1 Function IsXLBookOpen(strName As String) As Boolean
I would like to open a file in an application using vb.net 2008. I am unsure which namespace to use. I do not want to assume it is the current associated application. I believe there should be a way to... Dim app as something Open a file in that app
The below code works fine to export data from a datagrid to excel spreadsheet. Is it possible to incorporate an auto email (outlook) so that I can automatically send the spreadsheet to my manager lets say his email is abc@xyz.co.uk. What I want to do is when the spreadsheet is opened an auto email is sent with the spreadsheet attached to my line manager.
Private Sub ExporttoExcel() 'verifying the datagridview having data or not If ((DgvQuarCommit.Columns.Count = 0) Or(DgvQuarCommit.Rows.Count = 0)) Then Exit Sub [Code] .....
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?
I have an application that browses through Excel-files, changes color in some cells if they are in a wrong format etc.When my application is saving the changed file I get this alert about compatibility issues that can occur, and this alertbox has to be agreed or cancelled to move on to the next file. How can I disable this compatibility check programmatically? Or is there any way to ensure there are only Excel 2003 compatible colors in the document before saving?
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.
I am selecting a directory and then I want to loop through the files and check which xls and which docs are password protected and drop their names into column A in excel. I haven't gotten to the part of inserting into excel yet.I am trying to figure out how to check for password protected. I don't want to have to open each file separately.I am currently testing with excel, in a test directory i have one password protected xls and the other one is open. When i run my app both of them give me the message that they are password protected.I am not trying to crack password here...i am trying to enter the file names of the password protected xls and then remove them from the directory.
Tha Function IsProtected(ByVal filepath_x As String) As Boolean IsProtected = False
I have a program that at one point will open word and export some info. 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). It appears that everytime I start the program it opens a hidden winword session. It has nothing to do with the code I have on the form, it opens before any code I have written is executed.
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.
I have successfully automated a PowerPoint Metrics presentation with VB.Net. However, since there were many complicated calculations, it took quite some time to make the 120+ slide presentation - so I recently tried to revamp the application to be multi-threaded.
I've got VS2008 and Office2010, but I don't have Office2007. Therefore, I have the Word14 Object Library but not the Word12 Object Library. Will the code that I create for Office2010 automation also work where clients only have Office2007 or will they have to upgrade their office suites?
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've developed shared addin for Microsoft Word. I distribute this addin with my application and using Inno setup for installation. The Inno setup installs my application and then runs "myAddin.msi" file in order to install addin.
how to uninstall this addin programatically?
Right now, in order to uninstall addin, the user has to to it manually through control panel.
