Copy To Excel From App Causes A 0x800A03EC Error In Some Environments
May 15, 2009
Here is the error:
System.Runtime.InteropServices.COMException, Paste, Exception from HRESULT: 0x800A03EC
All machines are Windows XP with the same version of Excel (2003). Some machines get the error, some don't. We have yet to find a pattern.
Here is the code:
Public Shared Sub ExportToExcel(ByVal dt As System.Data.DataTable)
Dim app As New Microsoft.Office.Interop.Excel.Application
app.Visible = False

I'm wondering what would happen if my program was used say, on a computer with a chinese keyboard? I assume the text box controls will be fine, but sometimes I compare english strings.. such as "!" and "@" and a few other things.

I have a web application that works in our stage/test environment fine but once we moved it to our production environment something weird happens. All the control ids change. a label went from ctl00_cphMainContent_lblPetName to _ctl0_cphMainContent_lblPetName. Why would this happen? What could cause something like this to happen. The only two differences I know of are the production environment has HTTPS and I've disabled debugging.

Currently all my application that is released is always release in production. However I would like that changed and also have a development side (For testing).
I've tried searching for steps on how to create a development server however I cannot seem to find a tutorial.
In the past I've seen someone release their application in development by having it in on "Debug" option and have it released in production by having it on the "release" option. (I apologize for the vagueness as it was along time ago since I saw it).

Will LINQ's parallel extensions automatically detect the number of cores and utilize them all? Conversely, if the code is run on a single core machine, will it still work or do I have to detect the number of cores and tell PLINQ how many to run across? I don't have access to any single core machines to test my code on so I can't even test this for myself and I haven't been able to find any useful info elsewhere...
Also, while it might at first seem obvious when to use parallelism, are there any rules of thumb regarding where it should and as importantly should not be used? I don't necessarily program in a specific environment. I tend to divide my time somewhat equally (depending on project) between web, client/server apps, windows apps, windows service and console utilities depending on the task at hand.

I am developing an application in Vb.Net 2005 and have enabled the installation by clickonce, the update occurs before the application starts. My problem is very simple, the server that contains updates is correctly natted to be available from the outside with a public IP.
The clients who access from an external network connecting without problems, download software and updates. When local clients are connected to the same network of the server (LAN) can not download anything because they try to access the server with the ip public, and the nat does not work . We can not perform operations on the DNS server or hosts file and not even on the router.
I need to figure out if i can use ClickOnce to use more than one distribution server, primary and secondary. I'd like to set as the primary server the public address and the secondary server with internal network ip address.

I have successfully constructed several one-dimensional arrays and correctly passed them to an output subroutine. I am trying to pass/copy the values of each array to an Excel spreadsheet, but have encountered 2 problems.
Problem 1: The program fails on the following line: outSheet1.Range("B2").Resize(passFile1IndMax + 1).Value = passFile1Amount with the error message: "Value does not fall within the expected range"
Problem 2: When commenting out this line (and the corresponding one for passFile2Amount), the program no longer fails, however, the results show 8 rows (passFile1IndMax and passFile2IndMax both = 7) of the same data (e.g., A2:A9 all = 3/1/2011 = passFile1Date(0))--the first item in each array.I am trying to avoid looping through each index value and assigning values on a cellby-cell basis. Help...

I have 300+ excel files that need to be combined. There are 4 different types and in 4 different directories on my network. I need to copy the data out of each one and combine the data into a new single workbook (1 for each type). I have come up with a solution that does MOST of what it is supposed to do. Only problem is I can't figure out how to have the paste operation go to the same single workbook. No matter what I have tried it opens a new copy of excel to paste into everytime. Here is what I have so far.[code]...

I'm trying to copy cells from Excel to a new mail message in Outlook. Excel and Outlook both open fine but it doesn't copy.
Im using the following code:
Dim content = xlWorkSheet.Range("A1:C21").Copy()
Dim oApp As Outlook._Application
oApp = New Outlook.Application()
[Code]....
This does not copy the cells. It simply displays an email with a body that says "true".
I am using the excel sheet to do other things which work fine, so the excel code works. Just having trouble copying the cells.

I'm using the excel object model (importing namespace Microsoft.Office.Interop.Excel) to open an Excel.Application object in my code, then open a workbook, worksheet, etc. What I'm doing is ridiculously simple: I'm opening two worksheet objects; one is already populated with data and another one is empty and is supposed to be populated with some rows from the first worksheet. If some conditions, regarding cells in the first worksheet, are not met, then I want to copy the entire row in the second worksheet, at the first available row. I have an integer counter, initialized at 1, which indexes the first empty row in the output worksheet this counter is obviously incremented every time I insert a row at outputSheet.Rows(counter).
Every solution I've Googled either uses VBA (I'm looking for a solution based on VB.NET) or is not compatible with .NET framework 3.5 (I'm receiving exceptions at runtime). I'm guessing I'm not using the Range object correctly or something; in any case, what's the simplest way to do this? I really don't want to open an OLEDB connection to my excel file: this is too complicated for the simple row copying mechanism I'm trying to implement.[code]...

I have many files at work that need to be copied from one directory to another. However, I do not need to copy all the files at once.
I get excel sheets with the list of files that need to be copied once a week. So, in the main directory there is about 150.000 files and I only need to copy about 800 at a time.
I am thinking of having a textbox and an open dialog so I can pick the directory the main files are at - another one where I can choose where they will be copied to.
The problem is the list will be in excel sheet (column A). How do I have vb.net (2008) see the file names in column A and find them and move them?
Right now, I have macros in excel doing the job, however, I have so many things in this excel I need to transfer this part out and into vb.net.
The macro in excel doing the job is:
Code:
Sub CopyFiles()
Dim objFSO As FileSystemObject
Dim strSourceFolder As String

I have had a few programming courses in college, but I'm far from a VB expert. I work at a bank and I want to copy information off of webpages and put it into an Excel worksheet. I created a macro that automatically opens up Internet explorer -- but really what I need is a subroutine (or a method) that copies information from 1.1Million records / screens and places the information into MS Excel.There are 1.1M records, so ideally-- I like it to copy all information over a weekend and come in on Monday and be done. At the very least, I would like a macro that can run off of a shortcut and copy all information on a webpage and puts information into each respective cell. Ie. copies the name field and puts into the name cell in Excel... address field into the address cell in Excel.

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.
