Web Forms :: How To Check For File Exists On Another Website

Jul 29, 2010

I have two websites. One site contains nothing but image files. This is a sub-domain of the main website. The main website allows the user to search a database of information and displays that information. I create a grid with a link to the file. In my row_databound function, I want to check to see if that file exists on my other website. If it doesn't I remove the link, otherwise I leaves a link to that file. how to verify that the LINK actually goes to a file that exists?

Web Forms :: FTP Download - How To Check File Exists

Dec 7, 2010

What is the way to :

1) Check if a file exists on an FTP site.

2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.

We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.

How To Check If File / Software Exists On Client Machine

Jan 6, 2010

I'm having some trouble trying to create a page for my web app. I'm not trying to write a simple download/upload page. Should also say that I'm not trying to write a complex one.What I need to do is in the PageLoad check if the user has installed one particular software and then show the right message to download and install OR run it from the user's actual installation. For this scenario I've tried to use different file upload controls to check if the file was on the client machine, but none of then can do this, since, for security reasons,I can't programmatically set the path and file to upload.

Check What User Is Trying To Access A File?

Nov 29, 2010

i have an ASP.NET website which is using a filestream to read in a PDF image from a UNC share on a remote server 2003 box.

i attempt to load the file on the site (which simply embeds a PDF viewer on the site) but when i debug the code, it's throwing a security exception when i attempt to access the file. saying "access to ___ path is denied".

so... i granted access to the UNC path directory to the ASPNET user. i also granted access to the user that's specified for anonymous access in the site itself in IIS.
nothing.

however, i grant "everybody" access and the file comes through.

so, i need to know WHO is trying to access the file. the assumption is either the ASPNET user or the anonymous user setup in IIS. neither of which is gaining access. i tried to set up file auditing on the server2003 box but it's not logging a failure in the security event log when i get an access denied exception.

How To Check If A Record Exists

Jul 26, 2010

I tried to illustrate the problem by providing the following instructions, unfortunately the data was deleted and the example failed. It is now working. I have been working through one of Scott Mitchells ASP.NET Application Tutorials Title "Using TemplateFields in the GridView Control"

The URL is ...

The example demonstrates a temporary field being used in different ways, one of which involves dates in a Calender. If the HireDate in the example is deleted or not available the program fails. Providing the date is a valid date it works fine....

SQL Server :: How To Check If A Record Exists In VWD?

Dec 21, 2010

I am very new to this and have watched a lot of the videos. While trying out VWD2010 and SQL2008 Express, I come across many things, I just don't know how to do. Here is the latest:

I have a Table
UserId - Int - AutoIncrement
FirstName - Var(10)
LastName - Var(10)

I also have an ASP web page that allow the user to enter a first name and last name. It also has a button to submit. What I would like to do is have a Select statement check to see if the name already exists, then send a comment back to the user via a label. If it doesn't exist, then I would like to Insert the info and then again inform the user via label.

SelectCommand="SELECT COUNT (UserId) FROM Users WHERE ((FirstName=@FirstName) and (LastName=@LastName))"
InsertCommand="INSERT INTO User(LastName, FirstName) VALUES (@FirstName, @LastName)"
<InsertParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</SelectParameters>

On the code behind, I get lost. (Obviously this doesn't work, but I don't know how to go about getting a results back. Protected Sub bSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bSubmit.Click

SqlDataSource1.Select(DataSourceSelectArguments.Empty)
(get a return)
(check return value, if <>0 then
lblResults.Text = "exists!"
else
SqlDataSource1.Insert()
lblResults.Text="added!"
end if)

SQL Server :: Check If Value Exists Before Inserting?

Oct 27, 2010

I want to be able to check if a value exists before inserting a new record in the table. I am taking a nvchar value from a textbox and want to compare it to existing values in the table. My codebehind is:

[Code]....

It is also important to filter down by CompanyID which is held in a Profile table. So the value can be equal in records where the CompanyID does not equal the loggedin Profile.CompanyID. So a user with a CompanyID of 2 can have a value in the table for SubType as "laptop" but a user with CompanyID of 3 can still enter "laptop" if there is no match for "laptop" and companyId = 3.
