View 1 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
[code]....
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.

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

With vb.net I would like to select 4 cells in Excel and then pass those cell values along with 1 button tag to a formula in Excel.I press a button with a month, say "May" as text. I want to grab a cell in Excel labeled "May1t" the value of which is the number of hours until may. This is the code I'm using.
xlsWB.Worksheets(2).Range(Month1 & "1t").Value I am able to set a variable with this as the value but,
I want to pass this cell (which will be updating as the time counts down) and 3 other similarly specified cells along with the button tag to an Excel formula.I have something like this:
Private Sub F_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles F.Click
xlsWB.Worksheets(4).Range("B2").Formula = "=MyFunction()"
xlsWB.Worksheets(1).Range(Month1 & "1t").Select()
End Sub
The formula takes the parameters in the order: MyFunction(Cell,Tag,Cell,Cell,Cell).
