View 6 RepliesCOMPLETE NOOB, dont know anything.. I have a Virtual directory ~/ClubInfoFiles that i upload some files too using a uploader i made. I might want to change the uploader i made to be able to change to a subdirectory or something so i can upload all files into one folder but different subdirectorys. the uploader i would like to be able to have a dropdown menu of all the subdirectorys within "ClubInfoFiles" say i has subfolders : Minutes, Flight Plans, Maintence Records, etc... but i would also like a field to where i can create a new subdirectory and have it automaticly update the dropdown. i want to list those files in gridview and have a link to dowload/open and dellete the files. i have found some code that gets close but it uses Auto Generate columns. really i dont need all that jazz, just the Name, File extention, and hyperlink the file for download/view. i would like to be able to delete and possible upload using the gridview... is this to much for a noob?

I am getting error as mentioned below:
The process cannot access file "E:TempPDFsSample.pdf" because it is being used by another process
I happen to send the pdf from email and after email is sent i need to delete the Sample.pdf file. The code that i have written doesn't work
FileInfo DeleteFileInfo = new FileInfo(directoryPath + "\" + filename + ".pdf");
if (DeleteFileInfo.Exists)
File.Delete(directoryPath + "\" + filename + ".pdf");
here directorypath is E:TempPDFs, filename is Sample

I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1
2 Record2
3 Record3
4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1
3 Record3
4 Record4
...if I then hit refresh...
1 Record1
4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server">
<asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" />
</asp:LinkButton>
protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) {
if (e.CommandName == "Delete") {
int ID = e.CommandArgument.ToString().Numeric();
db.SPs.SpDeleteAccount(ID).Execute();
UI.Confirm(uiBroadcast, "Account has been deleted", "300px");
BindAccounts();
}
}
I am looping through a dataset and I would like to have the following in this array list
name, from, to, price
john, 40, 50, 39.99

etc.
Once I do that, or if it is possible to do it using the dataset that will work with me. But I want to do...

So in my code I wanted to make it easy for me and instead of memorizing the row #, I would just do.. arraylist.row("john").item("from")
