Combine Excel File & Csv File And Save As Excel.?
Jan 26, 2009
I'm working with vb.net 2008. My application generates 1 excel file (with login details etc). The application will store user results for various sections into csv files. I'm trying to combine the csv files into the excel file. I'm trying to get this to work with one csv file initially ...but I am ending up with a blank Excel file. This is what I've tried so far:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim oExcel As Object
[code].....

I have a folder with several excel files that have a date field, i.e. 08-24-2010-123320564.xls.I want to be able to have some VB scripting that will simply take the files that start with todays date and merge them into one file.

I need to create a dotNet saveAs dialog, but I need to populate the file formats in the dialog. After the person have selected a file, it must connect that to a file format that I populate into the SaveAs command in the Excel Interop. After the Interop SaveAs command, I must check if the file have been saved correctly.

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 program where I put data into a list view in VB.net. I then use the code below in a button click to export the content into a excel file where I can then save it. however I plan to add alot more data to the list view ad would like to auto save the data in the list view to an excel file (where it saves it to disk not an open excel window) and then clears the list view then will repopulate the list view and repet the loop of saving the data to a new excel file on disk.[code]...

I have a database file that excel reads just fine but i can't figure out what type of file it is. So i figure the easiest thing to do is open the file in vb.net via an excel object, then execute the save as i have seen 1000 examples but even after i think i add a reference vb still has no idea what "excel." is.[code]

I'm trying to import data from an Excel file into SQL server. However, the Excel file's format is not recognized by SQL Server. In fact, when I open it and try to save it, I get the following message:<filename> cannot be saved in the current format. To save your changes, click OK, then save it as the latest format.When I do that manually, it puts it in a usable format. However, the automated process I'm trying to build can't save it without intervention. When the VB in my SSIS process gets to it it brings up a save window, and I have to click the "Save" button and then the "Yes" button to replace the existing file. I'd strongly prefer to have this automated. I've have tried using the SendKeys.Send("{ENTER}") code, but it brings up this message:SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.I've tried SendWait, but it just seems to hang. I don't know how to change the application to handle error messages. I have also tried saving the Excel file as a new file with my VB code. However, as a new xls, xlsx, and csv file it still wasn't recognized by the import. I've only had success when manually saving it. In the SaveAs code I have been using, I'm only using the FileName parameter. I can't get any FileFormats to work or be recognized. Note, though, I'm opening the app and worksheet as Object variables. I can't add the Excel component in the Add Refrence area because only the .NET tab is there. I don't have a COM tab. I haven't asked if/how to get access to it, though.

I want to save an excel file with the following prefix: Order-Monday for Mondays, Order-Tuesday for Tuesdays etc and then this file will be overwritten the next week. For the following bit of vb
lstrDateStamp = Now().DayOfWeek
xlWorkSheet.SaveAs(gstrFilePathS14 & gstrFileNameS14 & "-" & lstrDateStamp & gstrFileTypeS14)
the Now().DayOfWeek returns '5' apart from doing a case expression to decipher 1-7 as days of the week is there any other way I can get lstrDateStamp = DAY (i.e. Friday)

I'm developing a small application that creates Excel files with user details. I'm developing this in vb.net 2008 express edition under Windows XP SP2 and with Office 2003.My target PC is running Windows Vista. I'm able to run my program without any problem and even the Excel files get created without any problem on this PC.However, the problem is when I try to open one of these created files in Vista, I get a message like below:
"The file you are trying to open, "TestMe.xls", is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" If I click yes, it opens up properly. This is a headache as it opens up in my developing PC without any hassle. I'm sure its something to do with the Excel reference I've made in my PC (which is running Office 2003).How best can I save this file so it opens up in Excel 2007 without the above message.

I have ran into an issue where I need to save some Excel data to a semicolon delimited file. (Why is an issue unto itself) And I can not find a way to do this using VB. In excel I can use Import Semicolon delimited files but I can not find a way to save them. Is there a VB constant or method I can use to save semicolon delimited files without having to write my own save procedure to format the data? such as the xlCSV, xlDIF, xlTextMSDos formats. I would think that since it can import this format that it should be able to save it.

Here are some important facts:
This code works (no Error 1004 on numerous laptops and desktops) A couple of months ago it began to fail (Error 1004 reared it's ugly head) on a couple of machines. The users claim that nothing changed - I can neither confirm nor deny accuracy of these claims. All users, except one, are running Windows XP and Office 2003. The problem also surfaced on a new machine running Windows XP and Office 2007. I could not force the error on my development/test machine - Windows XP with Offic 2003. It fails every time on another machine I have running Vista with Office 2007
The following is the code that causes me the problem. I know the error is raised on the WB.Save statement. I added the error trap to eliminate the problem of the Excel file being unaccessable without a reboot, due to the fact that Windows thought Excel still had it open.
Public Sub ExportCostAnalysis(ByVal RunMode As String)
On Error GoTo ErrorHandler

My query is i want to save record from an excel sheet to my Database Table.
But i dont want to insert the Excel sheet as a whole rather i want to insert the record in my database table Row wise.Inserting the records is not the only thing but my major issue is i want to check and compare the Primary Key column of my Table with the Column in my Excel.
Suppose Table1 is my Sql Database Table,and RegistrationNo is the Primary Key Column.Similarly there is also a column of Registration Number in my Excel Sheet.
Now before inserting each record the RegistrationNo column should be compared.If the a registrationNo in the excel sheet say RegistrationNo 112 is already present in the table then it should not Insert the record and if its not present then it should insert.
Also the other issue is the number of columns in my Database table are more than the number of columns in my excel Sheet.So the columns that are not present in the excel sheet should be set to NULL while inserting the record in the Table.

My company is making thousands of products now, every one of them have several test report in excel files. I am thinking about putting all of them into a microsoft sql database,
1. Is it wise to do so? I think a sql database is a lot easier to manage.
2. Can I save or convert the excel file as one data in a table? How could I do it? I only see a image type for data type. Surely I expect to retrieve the excel file through ASP.Net website if necessary.oh, some additional info, every excel file is not big, but it contains pictures inside sometimes.

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:
1) set a reference to the Microsoft Excel 12.0 Object Library
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'.
