VS 2010 - File Handling In Webform
Nov 6, 2014
One of the current projects I'm working on is converting an existing Access front end to a web app for a SQL Database. I wasn't involved in the original design of the, formerly, Access db and front end. I have the project nearly complete except for one remaining task, which involved links to part datasheets for a particular part.
The current db has a table with 8 columns "File1" through "File8". For each datasheet created for the part one of these columns is populated with the UNC path to the file, "<Server><Department>Documents<filename>.pdf". The Documents folder currently has over 16000 files stored there. The Access front end has a series of textboxes with associated file save, file open, and delete buttons for each. I could do the same think in the webform where I need to allow access but it doesn't seem very clean.
I've thought about importing the documents to the SQL db then use a fileupload method to maintain them, which I've used in apps for new databases but that seems like a daunting task with the existing db.
Any way to use the existing file path data in the db and existing document folder to allow access to the documents and the user to manage them?

I'm using a HttpHandler to intercept PDF file download requests and modify the PDF file. I'm stuck on what to do if the requested file doesn't exist on the webserver. If I handle the Exception and return an empty response, it gives the user a 0 byte file to download. If I ignore the Exception, then ASP.NET catches it and the user is redirected to my unfriendly customError page.

I´m creating a user page to enable editing their profiles. When hitting the "update" button, it turns out that the field still contains the old value, although you´re looking at the new one, ie the text property of the textbox isn´t the value of the parameter which in fact gets its value from the text property.As far as I know I haven´t done anything I haven´t done before, both in apps and website?
Fuga.
Code:
Update Persons set [First Name] = @First
Code:
.Parameters.AddWithValue("@First", Microsoft.VisualBasic.Trim(Me.TextBox1.Text))

I have a webform that has a bunch of textboxes (name, address, city, state, ect...) and a gridview that holds records of products (name of product, stock number, qty, ect...) How can I get all of this information into a csv file when the customer presses a "Place Order" button? Does anyone have an example in vb?

I have a large XML file and want to display out to the webform. So instead of parsing each xml node for the information, is there a quick way to display out the whole xml file to the webform without showing the xml element (display data only)?

In my new job, they have already written an httphandler to handle all the .aspx files, and they are not using asp.net's httphandler. Now, I want to use asp.net's regular .aspx httphandler for some web pages (.aspx files) in the project and the other pages need to be handled using their customized httphandler, i.e., 2 httphandlers for same file type (.aspx), how to do this?

I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %> [code]....

Assumptions: Microsoft stack (ASP.NET; SQL Server).
Some content management systems handle user-generated content (images, file attachments) by storing it in the file system. Others store these items in the back end database.
Some examples of both:

What's the best approach, and why? What are the pros and cons of keeping user files in the database? Is there another approach?

I have set up the maxRequestLength :-
<httpRuntime
maxRequestLength="10000"/>
Then I found this solution online to handle the error if someone tries to upload file bigger than 10 MB
[Code]....
This works great on my local machine but when I try to run it from Production server , It still shows me the "Internet Expolrer cannot display webpage". I just want to display a nice message to user when He tries to upload file larger than 10 MB.

Using C# .NET 3.5 with VS 2008.
I've been playing with the FileUpload control for an upcoming project where the user is allowed to upload up to five files at once, but each file can only be 5MB in size. Simple enough all I would need to do is add in the httpRuntime element to the web.config and up the file size and timeout.
[Code]....
what I'm really getting at is there a better way to trap if the file size is too large before processing while using the FileUpload control. I would like to be able to keep the user on the same page but update a label control.

not quite sure where I'm going wrong here. I'm trying to manually handle sorting in a Gridview that is populated with the following data source:
[Code]....
[Code]....
[Code]....
At the moment, nothing is happening when I click on the column headings. I ran it in debugging mode in Visual Studio and put a breakpoint on the Sorting event handler. I noticed that the variable dtSortTable is empty even after the TryCast(VacanciesGV.DataSource, DataTable). If I hover over this statement in debugging, it shows the data from the file system, so it does appear to be reading it.

I'm downloading a file from my intranet site and on Chrome, it works as expected. But when I try it on IE, it crashes.
ASP.NET Code:
<a href="../nbd.exe">TEST</a></h2>
Is there something I need to do just for IE?
Also, it works fine in Opera and Firefox. So just IE...

I am trying to read a text file from the root of the server. This is what I tried
Code:
Dim sr As StreamReader
Try
sr = File.OpenText("~ est.txt")
Label1.Text = sr.ReadToEnd
Catch ex As Exception
Label1.Text = ex.Message
End Try
If I test this locally, I get the error: "Could not find a part of the path 'C:Program Files (x86)Common FilesMicrosoft SharedDevServer10.est.txt'."If I upload it and run the code on the server, nothing happens (Lable1.text does not change).

I'm binding data from a SQL table to a GridView. The data looks like this:
During the initial bind, all I'm pulling is the raw data and adding it. As each row is bound, I convert the latter two columns into the hyperlinks like so:
VB.NET Code:
'Get the second link text      Dim lnktextBOM As String = e.Row.Cells(2).Text       'Create link      Dim lnkBOM As New HyperLink      lnkBOM.NavigateUrl = getSqlData.getBomURL("notebooks", e.Row.Cells(0).Text, e.Row.Cells(1).Text)      lnkBOM.Text = lnktextBOM      'Add the link to the cell      e.Row.Cells(2).Controls.Add(lnkBOM)
Which all works great. However, if I'm using Chrome and I click on the URL, nothing happens. On FireFox, a 404 is thrown. But on IE, it works perfectly.
what I'm doing wrong here? Below is an example of the URL:

it may not have to do with silverlight as such, but a "security" issue. I appologize if that was wrong.
I´m having a go at silverlight...
I want to display large amount of data in good looking charts. Ideally, I would use a web service. However none of the tutorials I´ve watched works. There´s always some component or class missing.
So I figured I´d do it the "ugly" way, creating a xml file from a dataset, and then reading it in the silverlight app.
Now when debugging, I use a local file, which is apparently not permitted
But there must be a way around it right?
