View 4 RepliesI have a master page, which has menus and submenus, and content pages in my project.
Now in one of the content pages, i need to open a excel file, displaying an Open/save dialog box) should be visible.
I tries using the inline option for Response.AddHeader, but does not display the master page part on the browser.
I have a text file with tab as delimiter. There are about 20 fields in the text file and the file size is about 150MB-200MB.
I need to filter out each row in the textfile based on its field criteria, For Eg: the i should ignore the particular row if the Field A is empty.
I know that by reading out the text file row by row it will be certainly slow.
how to read out the text file fast and also how to do the file processing for the read out text file?
I'm retrieveing pdf file from SQL Server 2008 and i wish to display it in new browsers tab. I successfully retrieved and displayed pdf document when i had pdf viewer installed.

I know the content palcehlder does not have a size ,I have a masterpage and content page, the master page has a table with a header, content area, and footer, header and footer are fixed size, content area is 100%. As the user sizes the browser the content area grows and shrinks and the footer stays at the
bottom of the browser window - perfect!
Problem: The contentpalceholder does not grow to fill the available content area. Now, the contentplaceholder gets its size from its contents, which in this case is a div holding a silverlight object.I was thinking I could hook the master or child page's re-size event and somehow pass that info onto the SL object, but as it turns out (and I'm surprised I never knew this) there is no aps.net page re-size event! (really?, wow.)
So is there a way to get a SL object hosted on a master page to size itself based on the size of the browser window?Or more generally, a way to size the contents (like a div or panel) of a contentplaceholder based on the browser? on a standard aspx page (not a master page) I CAN get the SL object to size itself based on the broswer, the problem seems to come from the fact that I'm hosting the SL object in a content placeholder.
I guess I could 'unroll' the master page into several standalone pages and have it work, but the menu is on the master page and I'm used to using them, plus it's already done...<sigh>
My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

View 1 RepliesWe have this great asp.net web application that generates word documents (wordprocessingML) and saves them to the file system on the server. We are running IIS 6.0. I would like to know the best way to allow the user to click a link or something so they can open the document from the browser. I have been experimenting with the Microsoft.Office.Interop.Word object, but am getting an error when I try to active the application object. I don't know if using this object is the best approach or if I should be doing something else.

any page that I open in my browser comes up blank.
I don't get any errors, it just comes up blank.
I also noticed that it seems to bypass forms authentication. For example, even though the page I open is blank, it is the actual page name that shows up in the browzer instead of the page that it usually redirects to for the forms authentication.

I have seen this issue with importing from Excel with the jet 4.0 engine, however I am importing a text file.
Is there such a thing as an optimum chunk size for processing large files? I have an upload service (WCF) which is used to accept file uploads ranging from several hundred megabytes.
I've experimented with 4KB, 8KB through to 1MB chunk sizes. Bigger chunk sizes is good for performance (faster processing) but it comes at the cost of memory.
So, is there way to work out the optimum chunk size at the moment of uploading files. How would one go about doing such calculations? Would it be a combination of available memory and the client, CPU and network bandwidth which determines the optimum size?
EDIT: Probably should mention that the client app will be in silverlight.
Is it possible to open a PDF always in a browser? That is no Download option will be provided by browser as a user will try to open that pdf file. My application is in ASP.NET (C#).
View 5 RepliesDeveloping a web application in C# which stores files in a tree structure in a server.
A project ( eg: ABC) has many sub folders (eg: ABC_sub1,ABC_Sub2...etc) . Each sub folder will have many types of files. (Eg: .dat,.txt .... etc)
I have stored the project name and the path to the parent folder ( in this case ABC) in a database.
Eg: \sereverNameTestMyProjectABC
What I need to do is when a user selects a given project ( eg; ABC) & clicks the link button component called "browse" to open the folder (\sereverNameTestMyProjectABC) in a new window.
This is the code I thought would work.
protected void LinkButtonFolderBorwse_Click(object sender, EventArgs e)
{
string myPath = @HiddenFieldFolderLocation.Value;
System.Diagnostics.Process prc = new System.Diagnostics.Process();
prc.StartInfo.FileName = myPath;
prc.Start();
}
HiddenFieldFolderLocation.Value gets the path of the parent folder (\sereverNameTestMyProjectABC).
When I click the link button nothing happens.
When the user selects the list of files from a page and hit's download selected, then a post back happens to server and starts zipping on the server. This works great until we hit the timeout on the page ( which is default to 90 seconds ) and just returns the process to the page even though the backend process is still zipping. Is it possible to show the size of zip file when the file is being zipped instead of waiting till the end to provide the download link?
View 1 RepliesI need to open a second browser window or tab, but it must have a different session ID.
Opening the new browser window from an ASP.NET page is easy, but then it shares the same cookie and thus session ID with the original.
i have an action that return a file content. i added:
Response.AddHeader("Content-Disposition", "attactment; filename:"" + survey.File + """);
so that the image would be opened in another tab/page, gets opened in the current tab/page. whats wrong with the header?

View 5 RepliesI have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}
