Execute HttpPostedFileBase.SaveAs Method?
Feb 18, 2010
I've got an asp.net mvc application that uploads a file and stores them in one of the directories where the website is located.
My question is... When you execute HttpPostedFileBase.SaveAs() method saving it with the same name as an existing filename on the folder, does HttpPostedfileBase overwrite the file?

I am not sure how to explain this but I will give this a try. Before, we had an app running on windows XP and all the reports were working fine. Now, the app is moved to windows 2008 server. There is one report in this app that uses Microsoft Interop.Excel which is used by component one. Apparently, interop.excel is not supported in windows 2008 with 64 bit running. After doing bunch of research, we have two options - either write this report again or execute this report from XP.
I want to try the second one. The interop.excel works fine in XP. A copy of this app is on this server. What would be the best way to execute this report from windows server 2008? It looks like i would have to connect to the XP server, get access to the app and finally the function that executes the report. Is this possible?

Boss comes in and demands that we change an existing dataload process written in .Net 2.0 to call stored procedures on two different servers rather than just one. In his mind (not a programmer) this should be a short overnight process. We have about 60 different SQL Commands that we need to change and test. Is there a simple way to do this that I can't think of? If there isn't we will use something like replication or database mirroring, which is my preference but is likely to get the cold shoulder from my boss, especially since I have never set these up before. A function that takes a SQLCommand as its argument and then iterates through as set of connections to execute the SQLCommand. Change all stored procs to call the same stored proc on a linked server.

I have many webmethods in one asmx. I need to perform licence checking before some of this webmethods invoked. I can insert following code to each web method that needs checking:
if (!AllRight())
{
// badRequest
return;
}
Or I can insert complex filter to HttpModule to detect webmethod by URL. I need something like attribute for webmethod and place where I can handle it. Is there pretty good solution?

When my page is first loaded i receive error message stating to the effect
cant find Email for GetInvoicesByVendor.
this refers to a function in another class file:
Public Shared Function GetInvoicesByVendor(ByVal Email As String, ByVal vendorid As Integer) _
As IEnumerable
yet i only want to execute this function during the button click event and not when page is first loaded with the following parameters:
vendorid.Text = 1
txtcustomerid.Text = test@yahoo.co.uk
My objectdatasource is declared as follows:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
OldValuesParameterFormatString="original_{0}"
SelectMethod="GetInvoicesByVendor" TypeName="InvoiceDB">
<SelectParameters>
<asp:ControlParameter ControlID="txtcustomerid" Name="Email"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="vendorid" Name="vendorid" PropertyName="Text"
Type="Int32" />
</SelectParameters>

I'm using asp:fileupload control to upload my Picture files. So the user click on browse and select the file and click on upload and in event handler of upload button there is FileUpload.PostedFile.SaveAs () etc.
Everything works fine. Accept when for big file size. e.g. I've got a file (jpg) 5.5 MB. When I try to upload this file I get an the error below.
The strange thing is I the button upload file eventhandler I check the file size. If (intFileesize < intFileSizeLimit) etc.
But the strange thig is I remove all the code in Upload eventhandler for testing/debugging and I still get the error below. So the error occurs outside the Button handler. I mean the error cause is not by Fileupload.SAveAs etc.... So the question is how can I avoid this. I mean I have built restriction of 1 mb, but This code is not reached.
I don't have any problems with small sizes e.g. I could upload 400 kb w/o problem.
So the question is what is the cause for the big file size how can I solve this?
Other question is: Is there a tool or whatever to crop the filesize and upload? I mean even if they upload 6 mb picture, I should crop that to 50kb or whatever during upload. How to aproach this? maybe a 3rd party freeware?
ERROR I get after 2-3 seconds
Oops! This page appears broken. HTTP 404 - File not found.

I have this method which does not build, it errors with the message:
Cannot implicitly convert type 'System.Web.HttpPostedFile' to 'System.Web.HttpPostedFileBase'
I really need this to be of type HttpPostedFileBase instead of HttpPostedFile, I have tried boxing and it does not work:
foreach (string inputTagName in HttpContext.Current.Request.Files)
{
HttpPostedFileBase filebase =HttpContext.Current.Request.Files[inputTagName];
if (filebase.ContentLength > 0)
{
if (filebase.ContentType.Contains("image/"))
{
SaveNonAutoExtractedThumbnails(doc, filebase);
}
}
}

I have a standard FileUpload control, which calls a class library, where the file becomes HttpPostedFile. In beta versions of my page, I've been able to successfully use HttpContext.Current.Server.MapPath(filename)to save the file. The class library does various functions, including saving the image into /uploads and a thumbnail into/thumbs.
But now, after tidying up the layout of the site, the upload aspx page has moved to a subdirectory 'members'. I had assumed (wrongly) that calling the upload function would act as normal. However, now I receive an error because of where the page is originating from: The code wants to save the file in the non-existant folder /members/uploads and /members/thumbs
My question is: Apart from hard-coding the directory structure of my hosting provider, is there any way to use an equivilent to server.mappath which will recognise the root path of the website, and ignore sub-folders?
One method which solves my problem is to append "../" to the start of the file location, eg HttpContext.Current.Server.MapPath("../" & filename) ...However, as many pages will be able to call the upload class library (and not all of them in a sub-folder) I want to make sure I'm not always back-tracking on the subfolders.
