.net Saving Excel File?
Aug 25, 2010
I am exporting my values in my textboxes to an excel spreadsheet (user clicks "Export" button on form). After it is done, it asks me if i want to overwrite my current excel spreadsheet. Is there a way that I can open a save as dialog box so I can choose what name and where to save it?

I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?

I have a windows form application written using vb.net 2005 to generate and save an excel file. I faced some problems with the saving of excel file. The program will prompt a message box with 'Yes', 'No' or 'Cancel' options if the existing file exists. If user choose 'Yes', it will override the existing file. If user choose 'No', it will open a savefiledialog to allow user to specify the location and name to save the file. Do i use filestream object to save the file when user choose either 'Yes' or 'No'? How can i go about doing it or where can i find sample coding.

I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow

Here is my situation.
data = "" & data & ""
xlsheet.Range(crange).Value = data
xlfile.SaveAs(FileName:=finalfilename, FileFormat:=6)
This code puts " around the data, puts the data in the range and saves the workbook(xlfile) with one worksheet(xlsheet) as a csv file.
If I open the csv file in notepad I find these following
1.quotes are removed
2.leading 0 from numbers are removed
How to ensure that quotes are present while saving the file programatically?

I have an Excel file with utilizes macros to allow a user to enter names of people and then double click on cells to enter ratings via radio buttons. When I open a blank file and enable the macros, I can add users, rate their skills using the radio buttons, etc. with no issue. I then SaveAs the file and continue working on it. once I Save and CLOSE the file, then go to re-open it, the trouble begins. Keep in mind, there is no alteration to the macros directly. Just entering data and using the form as intended. Here's what happens.
I reopen the file.I enter in the name of a person on one line. I go to the first box - double click on it.It is supposed to pop up a dialog box which allows me to choose a rating via radio button (as I had been doing before I closed the file). Instead, in that first column of ratings, it instead gives me the following error:
Runtime error '1004'Unable to set the LineStyle property of the Border class
When I hit "debug" this is the code it points to:
If ActiveCell.Column = leftb Then Range(Cells(ActiveCell.Row, leftb), Cells(ActiveCell.Row, rightb + 1)).Borders(xlEdgeTop).LineStyle = xlContinuous I have no idea why this would not work when I re-open the file!
note that when I go to click on the subsequent cells (there are 8 cells in which you provide ratings, moving across the columns with each cell) - the 2nd through 8th cells function fine. The dialog box pops up, the rating can be selected. it's just the FIRST cell that gives the issue What would possibly be the cause of this? We need users of this form to be able to save, close, and re-open it if needed.

I have a form that exports to an Excel worksheet (sheet1) and it works great, no issues there or anything. It's not a template, just a regular .xlsx spreadsheet, but I use it as my template. Now, the goal is for the end user to be able to fill out the form, and save it as todays date. How does it get todays date? In the Excel sheet, N2 is todays date, and it gets it from the form. Then save it in a specific folder.

I am working on saving excel objects to a directory of my choosing. I am able to use a folder browser dialog to select the save location and the saveas method within the excel interop and i am able to create a file in the folder i select with the name i choose. The issue is that when i later go to open that file it is blank. no workbooks no worksheets etc . Just a seemingly blank file in the proper location with the proper name.
It should be noted that if i single click on the report icon to open it the microsoft browser window does show a tiny preview of what seems like the correct report.
eapp.Worksheets(1).SaveAs(FileName:=patient_frm.savefolder & "Lateral Postural Analysis")

Very first time I debug the coding I haven't got much problem. But debugging it again gives me an Error AS: "A file named 'Resume.XLW' already exits in this location. Do you want to replace it?"
I was able to see this since I have enabled the display alerts. Disabling it generates a save as window.

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

I have a VB.net applications that runs on XP and creates a directory and creates an Excell workbook and saves it. But when I do the same in Vista , when it tries to create a directory to save the excel workbook, it gives me an error that the directory does not exist. If I create the directory manually, it still gives me the same error. Is there a COM call for office 2007 on Vista other than worksheet.SaveAs(FileName:=path). All else works on Vista apart from creating a directory and Saving Excell Worksheet.

I'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:

2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module
3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.
