Office Automation :: Excel Process Won't Quit?
Nov 13, 2009I'm trying to create an excel file and load headers into the first row and then save the file to the local computer for later use. All of that works fine, but for some reason the "EXCEL" process won't quit. I have read through the tutorial written by Mike R and I have even tried just copying and pasting the code from the tutorial into my project, but to no avail. I should also note that I have not yet tried the "Extreme Measures" listed in the post, though at this point I am tempted to.
Code:
Dim ExcelApp As Excel.Application
Dim ExcelWorkBook As Excel.Workbook

Classic Program Instantiated Excel Won't Close On Quit
Jul 31, 2009This runs correctly, but Excel remains active after close.
If I don't create the range objects below, everything seems to work (with no output of course). Does anyone have any idea on how to keep Excel from staying in memory. Also... in the tests I'm running, I do not make the application visible.[code]...

Quit An Excel Macro Externally (from A GUI Not From Macro)
Oct 21, 2010I'm have a program (GUI) that interfaces with excel to execute macros. We're using Microsoft.Office.Interop.Excel to call/run the macros and this works great.What I can't figure out is a good way to cancel the macros from the GUI.One idea we had was to use the excel.application variable that runs the macros to write a "stop" value to a specific cell in the workbook, and in the macros (they are all mostly loops), check for the "stop" value in that cell. This crashes my GUI with this The program '[2188] BVLReports.vshost.exe: Managed' has exited with code -336589910 (0xebf00baa).And excel gets tied up, and won't respond. I know how to Exit Sub from within the macro if the "stop" value exists, so I don't need answers on how to check/cancel from inside the macro. Any ideas on a better way to write this "stop" value or a better way to cancel the macros externally?
View 2 RepliesChecking When Process (EXE) Has Quit?
Jul 24, 2010I have an external (3rd party) EXE which I start from my app, which reads data from the user and creates a corresponding registry key with the information, then exits. I then need to read those registry values from my main application.
I start the app with:
Process.Start(My.Computer.FileSystem.SpecialDirectories.Temp & "GatherInfo.exe")
I need to read those registry values AFTER that EXE has quit - so I know they've been created. At the moment I'm just making my main app sleep after that process has been started:
System.Threading.Thread.Sleep(1000)
And then checking for the reg values. I'm worried this won't work for different users however, as the speed of the computer will determine how long the process takes to start and exit.
App.quit With Multiple Apps Open?
Mar 3, 2010My program opens an excel file with excel.application's .visible=false. If the code is running and I manually open any excel file the excel file being used by code will then open up as well (making the .visible=false useless). Then at the end I use the excel.application's .quit to make sure that instance of excel quits, but it will quit every open instance of excel (even ones not opened by that code).Is there any way around this? to make sure it does not appear when other files are opened, and to make sure it only closes that one instance of the excel application.
View 4 RepliesUse The Information And Connect, Otherwise, Quit The Program?
Jan 31, 2011So i am writing something for work, and i was roaming the internet to see how to do it in vb.net, but it seems to really not have many hits. vb.net doesnt recognize Declare and all information points to things that say Private Declare Function [info]What i was wanting to do is to check if a computer has a DSN card in system DSN's, if it has it use the information and connect, otherwise, quit the program.
Do you know where i can find how to do this? I just need to check for the existance, i dont need to make them.All of my search results, while seemingly useful, were not written for vb.net I want to get something up here specifically for vb.net so we can get more search hits. i find more information, i will post it, but it doesnt seem to be going too far in the vb.net department, as it is in .net

View 3 RepliesInternet Explorer Object - Tell Webbrowser Control To "quit" Or Destroy It Self?
Oct 12, 2009In VB6 I used internet explorer object a lot. There things internet explorer object can do that webbrowser control cannot. For example, internet explorer object is easier to debug because when the application is in debug mode, internet explorer object is still interactive with client. Also we can clear cookies and resstart with internet explorer object. We can do ie.quit, then set ie=new internetexplorer then ie.visible=true
In vb.net internet explorer object becomes webbrowser control and I have no way to do that? How can I delete cookies and then restart webbrowser control? How can I tell webbrowser control to "quit" or destroy it self? That sort of thing.
Hook Excel - The Process Excel.exe Doesn't Finish After Close Excel
Jul 20, 2010I need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application
[Code].....
The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.

Feb 23, 2011I want to encapsulate the use of Excel Interop to make it easier to use somehow in a reuseable library.So far, I have written some tests that work good altogether, except that between each test, I force Excel to quite so that it does have handle on the test file no more in order to be able to delete.Once I quit the application instance between after each of my tests, Excel seems to be no longer responding, causing Windows to display "Excel has stopped working and is looking for a solution"

Office Automation :: Excel Program Leaves EXCEL.EXE Floating After Completion
Feb 24, 2012I 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.
Using The Microsoft.Office.Interop.Excel.dll Library; Does Excel Need To Be On The End User's Machine
Nov 22, 2011I have been doing a lot of reading on this topic and most folks seem to agree that having Excel is required to use the COM Interop libraries. However they are never specific as to where that should be installed. Does it need to be installed on the machine I am developing on or does it need to be on every machine that I deploy to?
Edit: I should mention that this is desktop development/deployment targeted for all Windows machines.
.net - Exporting To Excel Removes Leading Zeros. Css Styles To The Table Does Not Carry Over To The Excel Export?
Aug 4, 2011I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.
