View 1 RepliesI have a VB.NET application which opens Excel and writes data to it. The program works fine in debugging and publishes without problems. The problem I am having is that on some machines the finished program is throwing up the following error: Exception from HRESULT: 0x800A03EC..It happens when the program is trying to communicate with Excel. I am using late binding as this program will role out to our clients and I have no way of knowing what version of Excel they are running.This is the code I am running: (Those variable not in the Dim list are Pubic variables sitting in a seperate module. As I said the code runs fine so I think the problem is the way I am handling Excel)[code]
View 2 RepliesThe ExcelClass.vb code used to be in a module(Changed it to classes), and I found it online. Unfortunately, I can't find the link .The program is supposed to look through one file (I call it, the donor, cell, or excel throughout the program) and compare the values found in Column C to the values found in column B of another file, called "definitions". If it finds a match, it'll take the abbreviation in definitions and paste it over the value in column B of the donor sheet.The code maybe solid, I think it is, but I can't find out. It crashes with the above error as soon as it comes time to use the getCell function.[code]
View 5 RepliesI used Visual Studio 2005. It works well when testing, but when I publish it got error: Microsoft Office Excel cannot access the file 'D:OfficeStationaryV0.2ReportTMPReportItem.xlsx'. There are several possible reasons: - The file name or path does not exist. - The file is being used by another program. - The workbook you are trying to save has the same name as a currently open workbook.
my following code is:
Dim ExcelApp
As New Excel.Application
Dim xlWorkBook
As Excel.Workbook

I have used the Process.start function to open an Excel file as shown in the code
Process.Start("report.xlsx") and it works perfectly well.
My question is can this function be used to open a particular worksheet called Report1 in the report.xlsx file. If so what would the code be.I have spent many hours trying to research this topic but without success.
What I need to get done here is not a GUI, like the SQL Import and Export Wizard, which can be run from the SQL (2000) Enterprise Manager only, but a code that I can run from within the Visual Basic For Applications IDE from Microsoft Excel 2003, maybe in the form of a module, class or userform or a combination of all three. The best that I have come across so far, was a class that first checks if the worksheet is in a database formattable condition, then creates the database, if it does not exist, a table and then transfers the data from the worksheet to the table.
I have tried the Access 2003 TransferSpreadsheet method, but that does not solve my purpose, because I want to move the data from Excel to Access, starting from the creation of the database itself.
Exporting access into excel wks is easy, but how to import it back in?

View 1 RepliesI've recently converted some VB 6 code over that used the old non-structured exception handling. I also have some .NET classes that raise custom exception classes. When the code was VB6 I used to expose my .NET classes using COM interop and errors raised from .NET classes were being caught correctly in VB6. Now that everything is .NET the old non-structured exception handling is still there in the converted classes. But now the Err.Number is not reflecting the HResult of the error raised. I wrote a simple little Windows Application form with 2 buttons to simulate the problem. Here is the code snippet:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo ErrHandler
Err.Description = "Test Error"
[code]....
If you click Button1 you get the following message:
-2147215379 : Test Error
If you click Button2 you get the following message:
5 : Test Exception

Basically, when you click on a function icon within the software application it throws up the following message in box:"An unhandled exception has occurred in your application. if you click continue, the application will ignore this error and attempt continue. If you click quit, the application will close immediately"The specified module could not be found.

This happens on two systems; Windows XP SP2 or SP3 - .net framework 1.1 & 2.0 & all necessary patches etc installed. Just can't seem to get around it. What is more frustrating is I have a test rig that has exactly the same software attributes & it works fine on that.I have even tried full clean O/S install with no other applicationms installed & get the same eratta as above.
