Importing CSV Files - Path Spelled Correctly And Connected To Server
May 21, 2010
I have this code
Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & Request.ServerVariables("APPL_PHYSICAL_PATH") & "dynamicuploadedLists" & strFileName & ";" & _
"Extended Properties=""text;HDR=Yes;FMT=Delimited(,)"";"
''You must use the $ after the object you reference in the spreadsheet
Dim myData As New OleDbDataAdapter("SELECT * FROM [" & table & "$]", strConn)
'myData.TableMappings.Add("Table", "ExcelTest")
myData.Fill(myDataset)
And I am getting the error , while the path is correct.
'E:missitenamedynamicuploadedListsSheet1.csv' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.
I get the error after uploading my ASP.NET solution to server:
[NullReferenceException: Object reference not set to an instance of an object.] wwwroot.CLASS.Website.clsIndex.SAN_PHAM_MOI_NHAT_FILL() in C:jasmine.arvixe.com ukhi89hoasacmau.comwwwrootCLASSWebsiteclsIndex.cs:66 wwwroot.index.f_BindDataToDataListMoiNhat() in C:jasmine.arvixe.com ukhi89hoasacmau.comwwwrootindex.aspx.cs:32 wwwroot.index.Page_Load(Object sender, EventArgs e) in C:jasmine.arvixe.com ukhi89hoasacmau.comwwwrootindex.aspx.cs:23 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +99 System.Web.UI.Control.LoadRecursive() +50 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627
C:jasmine.arvixe.com ukhi89hoasacmau.comwwwrootCLASSWebsiteis the path on my computer and I don' understand why website on my server point to it (I uploaded successfully)????How to update the path of ASP.NET Web Application correctly for the server??
I have a task to upload multiple images to server path of the application folder . I have used the File Upload control in order to Upload the Images to server path but some images of about 778 kb are not supposed to be uploaded correctly. And while displaying the Images I am using Datalist control.
While I have tried to upload from Application in my system all files got uploaded but while acessing the link some files are not getting uploaded.
I need to populate a database (SQL Server) with some data from a templated excel document.Here are some approaches:
A) User upload a file.xls or file.csv that the server reads, checks and updates the database (cons:the uploaded file might be too big. file.* needs to be in correct format)
B) User downloads a tool.exe to read and upload file.xls (cons: maintenance of the tool.exe)
C) Use of a web service in excel? (don't know how to do it) but this article might give you a hint
Which one is the best to use? Are there any others?
The Microsoft Jet database engine could not find the object 'MyDataFile$'. Make sure the object exists and that you spell its name and the path name correctly.
below is my code, i am exporting my excel sheet in HTML format. in case of importing i am facing the above mentioned error.
I need to download files from server through code. The files are located under the server's C://DownloadFiles/*.txt, but i dont want to give hardcoded path in the code. My query is can we use Server.MapPath here, if yes what will be the syntax for this.
I've got a project that's going to go on a dedicated server environment. I'll be uploading images to the server, but saving them outside of the virtual folder path of the actual website, like so:
Now, this works fine on my home computer. Is there anything I'll need to do with IIS or ASP.NET (possibly in web.config) for this to work properly on a production machine? Settings or permissions that may need changing?...
It will be on Window 2003 with IIS6 and ASP.NET 3.5 SP1.
I am working on my first ASP.NET Website using VWD and C#. I did some inital design with Expression Web 4 such as created a master page with 2 content place holders, 2 style sheets 1 for the layout and 1 for the nav menu, and some images in a folder. I started with an empty ASP.net site opened my masterpage and saved it to the VWD directory. Now my Solution Explorer contains a MasterPage and a webconfig .cs file. I would like to import the style sheets and images I mentioned earlier but I am not sure how to accomplish this. do I have to open and save as all these items or can I impot them? Do I use the ADD NEW Item command?
For some reason I have a solution with a single project and the solution files are in the same directory as the project is. I consider this ugly and want to change it by moving the solution files in a superordinate directory.
For now I have edited a single line in the .sln file:
Before my time at the company they paid for a very expensive website written in asp.net and dotnetnuke. Absolutely terrible but there's very little that can be done about that now. They won't give us access to the SQL Server for some bizarre reason but they've given us FTP access.
Is there some way I can install a database manager (like phpMyAdmin) using FTP? I think I've found the username and password but I'm not familiar with asp so it's quite a confusing system.
I have a table with 100 records. I need to import extra 50 records in the same table. So from 101 to 150 records should insert the data which is present in excel Simply I want to import 50 records from Excel to Table without disturbing the first 100 records.
I got an excel spreadsheet (will have tons eventually) that have "Start Date" and "End Date" columns, with a format of "dd/mm/yyyy".For time being, I just want to import these to a temporary table in my database, and use the SQL Server Import/Export wizards.
Now this wizard import the the above fields as nvarchar, instead of date or datetime (not sure which would be better?).I tried to convert the columns to datetime after importing, but this is not allowed (Saving changes is not permitted. The changes you made require that the following tables to be dropped and re-created, ......).
So I deleted the temporary table, and ran the wizard again, this time trying to edit the mappings and specify the two fields to be date times, but this also fails.I also fiddled around with convert and cast, but always end up getting "Conversion failed when converting date and/or time from character string." errors.
I looked myself skew, and are pretty sure all the fields in the excel sheet do have values, and are in the "dd/mm/yyyy" format.(I've been absent from SQL for a long long time!)
I am trying to insert data from excel file into sql server database table. which is working fine.. But when i tried it in table which has primaryKey As Autonumber and date as getdate(). its not inserting values in rows?
importing excel/spreadsheet into sql server using C#? Whenever I run the webpage by selecting excel file, first it will empty sql server table then import data from excel.
i am currently working on importing excel sheets into my database.
SqlBulkCopy seems to be working fine, when i whole import the data over.
But i can't do automated validation (i.e. checking for identical data in the database & etc, i am stuck!) i can import the excel sheet data a line at a time , and perform automated validation check on them.
from an Access database, I created an Excel spreadsheet. On the spreadsheet I made the adjustments I needed to and then proceeded to use the SQL Server 2005 Import/Export Wizard to import the spreadsheet into a SQL table. I then get the following error message:[Code]....
When I remove the problem columns from the import, then it works just fine. But I really need those text columns! The SQL Server columns that they are supposed to go into are varchar(MAX).
I am having issues debugging locally within Visual Studio 2010 on Server 2008 R2 (x64) for a new ASP.Net MVC application. I am able to debug using the VS Development Server (Cassini) but when I change to use the Local IIS Web Server and Create Virtual Directory, I am unable to debug. I get the standard VS message:
"Unable to start debugging on the web server. The web server is not configured correctly. ..."
Everything looks standard in IIS. The Default Web Site is running under the ASP.NET v4.0 application pool. The virtual directory that Visual Studio created is running under the same app pool. I am running Visual Studio as the Administrator account. It feels like some security setting or something is preventing this to work but I'm at a loss to what it could be.
