SQL Process Design Connect To Multiple DBs?

Aug 11, 2010

Web server running an ASP.NET site that's connected to a sql server instance for all the web related DB needs (products, pricing, users, etc.)...

The companies accounting, inventory control(FIFO, etc.) and whatnot are mainly done on another system which uses a different SQL server...much more complex, for obvious reasons.

What I Need

What I need is to retrieve the current quantity on hand for every product that's on the web by connecting to the internal accounting sql server, even though the website uses a different sql server for it's own requirements.

The reason I can't have the information that is required to calculate the quantity on hand for every product on the web to be on the same sql server is because there are way too many tables that are needed to calculated that information...what's on purchase order, what's on sales order, and the physical inventory.

What is the best way to accomplish this without altering either database?

Configuration :: Allow Process Connect Via Ftp To Another System (under Win2008R2 & IIS7.5)

Aug 31, 2010

I have code that runs under IIS6 & ASP.Net 2.0, that won't run under IIS7.5 on Windows Server 2008 R2. I am assuming I have a configuration problem - but I don't know. On a Windows Sever 2008 R2 system: From inside IIS (v7.5), an ASP.NET process will not connect to port 21 (ftp) on the ICS (using System.Net.Sockets.Socket), it fails, logging an error that it cannot connect to the system at nnn.nnn.nnn.nnn. But, from a command prompt on the same server though, I am able to connect via ftp to the system at nnn.nnn.nnn.nnn. I am using the DefaultAppPool.

Here's a code snippet:

[Code]....

And the connect throws an exception - unable to connect I'm firing up wireshark soon and I'll see what if anything is getting across the wire? particularly if you think it's administrative in nature, cause that's a real weak point for me.

Web Forms :: Can Process Multiple Buttons With One Click Event

Sep 23, 2010

I want to dynamically build a table where each of the first three cells may or may not contain an image. If a cell contains an image, it may or may not contain a radio button. The last cell contains a button or link button. I want all the buttons to be handled by the same click event. The number of rows, which cells will have an image, and which cells will have a radio button is not known at design time. Finally, the images are displayed using the better image control.

I'm trying to get this to work usinging a repeater, but at the moment I can't get the radio button checked propety to change from the default value. I'm using an arraylist as a datasource. I thought of using a gridview, but I don't know how to add a radio button and a better image control to a cell.

Web Forms :: Process Radio Buttons As 'group' Allowing For Multiple Selections?

Feb 25, 2011

the form has 15 items to choose with radio buttons, any number can be selected. I would like to process them as a 'group' so I can do something like loop thru them, checking if each one has been selected to build a list and also be saving them to a table row, etc but it seems all the designations as a list or group make it mutually exclusive. just looking for better coding than checking them with an if statement or similar so the question is if there is some way to designate the radio buttons as a group but no force the group to be mutually exclusive

Using Entity Framework To Connect To Multiple Similar Tables In MVC?

Jun 10, 2010

A relative newcomer to .net MVC2 and the entity framework, I am working on a project which requires a single web application, (C# .net 4), to connect to multiple different databases depending on the route of access, (ie subdomain).

No problem with this in principle and all the logic is written to transform the subdomain into an entity connection and pass this through to the Entity Model.

The problem comes with the fact that the different database whilst being largely similar in structure contain 3 or 4 unique tables bespoke to that instance.

To my mind there are two ways to solve this issue, neither of which i am sure will be possible.

1/ Use a separate entity model for each database. -Attempts down this route have through up conflicts where table/sp names are the same across differnt db's, or implicit conversion errors when I try and put the different models in different namespaces. or

2/ Overwrite the classes which refer to the changeable database objects based on the value of a base controller property.

My question is if either of theser routes can ever work in principle or if i should just give up on the EF and connect to the dtabases directlky using ADO. Perhaps there is another way to solve this problem i haven't thought of?

Data Design - Multiple Short Trips Versus One Big Trip?

Jul 20, 2010

Is it better to have the calculated field returned with the rest of the results or is it better to calculate it later when you need it?

Example: I have a GridView that displays search results that has many fields like:

Application ID
Name
Account Type
Account Number
etc.

The account number field is not always consistently the same thing though. For accounts of type A they are eight digits long and for accounts of type B they are twelve.

After the search if they select a record and choose to continue the application I need to check the eigit digit account number for any access restrictions. All accounts of type A and B have an associated eigit digit account number, it is just that type B are the only ones to have the twelve digit number.

So should I add a redundant hidden field like "Common Account Number" to the search results and just hide it, thus making the heavily used search take slightly longer and making the results grid take up more space in the view state?

Or

Should I call the database when they try to continue the application and translate the Application ID into the eigit digit number so that I can use it to do my access restriction check? This will require one extra call to the database but the translation should be fast as both fields are in the same table and the application ID is a primary key. The continue application button will be used less as there are many other command options.

Configuration :: Process.start (System.Diagnostics.Process) - Execute A Batch File

Sep 7, 2010

I've written a aspx.net(C#) page that after the user has done what they do on the page they hit a Submit button. The Submit button

1) takes the work the users was producing on the page and writes it to a file.
2) attempts to execute a batch file.

The call to the batch file is executed via:

protected void Execute123EDI()
{
try
{
string File = @"c:80sAdminSendV80s.bat";
lblCancelled.Text = lblCancelled.Text + File;
Process proc = new System.Diagnostics.Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.LoadUserProfile = false;
proc.StartInfo.UserName = "administrator";
proc.StartInfo.RedirectStandardOutput = true;
System.Security.SecureString secPass = new System.Security.SecureString();
string paswd = "123abc";
for (int i = 0; i < paswd.Length; i++)
{
secPass.AppendChar(paswd[i]);
}
proc.StartInfo.Password = secPass;
proc.StartInfo.FileName = File;
proc.Start();
FileStream fs = new FileStream(@"c:80sAdminSendV80sOutput.log", FileMode.Append);
StreamWriter sw = new StreamWriter(fs);
sw.Write(proc.StandardOutput.ReadToEnd());
proc.WaitForExit();
sw.Close();
proc.Close();
}
catch(Exception ex)
{
lblDebug.Text = lblDebug.Text + ex.Message + "<br/>";
}

If I watch the processes tab in Task Manager on the web server I see "cmd.exe" under the context of 'administrator' but it just hangs. For test purposes c:SendV80s.bat: copy c: oot.ini c:zzz.txt

If I logon onto the webserver's console and execute SendV80s.bat it works and exits without issue. But when I execute the same batch file via the Submit button it gets stuck executing in Task Manager/Process. I believe this has something to do with the fact that cmd is not running in a full environment/desktop context. I just noticed this on the actual console of the webserver (not in my RDP console but console 0 instead)

A pop-up box stating: CMD.exe Application error The application failed to initialize properly (0xc0000142). Click OK to terminate the application. And when I click on the OK button my ASPX page's WaitForExit is satisfied and the continues processing normally.

Long Running HTTP Process - How To Put In Separate Process

Jul 21, 2010

I know that similar questions have been asked all over the place, but I'm having trouble finding one that relates directly to what I'm after.

I have a website where a user uploads a data file, then that file is transformed and imported into SQL. The file could be up to 50mb in size, and some times this process can take 30 minutes or sometimes even longer.

I realise I need to palm off the actual work to another process, and poll that process on the web page. I'm wondering what the best approach would be though? Being a web developer by trade, I'm finding all this new Windows Service stuff a bit confusing, and I just wanted somewhere to start.

So:

Can I do / should I being doing this with a windows service? if so, how?

Should I use WCF? If this runs under IIS, will I have problems with aspnet_wp.exe recycling and timing out my process?

clarifications

The data is imported into sql, there's no file distribution taking place.

If there is a failure, it absolutely MUST be reported to the user. The web page will poll every, lets say, 5 seconds, from the time the async task begins, to get the 'status' of the import. Once it's finished another response will tell the page to stop polling for status updates.

queries on final decision

ok, so as I thought, it seems that a windows service is the best idea. So as to HOW to get it to work, it seems the 'put the file there and wait for the service to pick it up' idea is the generally accepted way, is there a way I can start a process run by the service, without it having to constantly be checking a database table / folder? As I said earlier, I don't have any experience with Windows Services - I wondered if I put a public method in the service, can I call it somehow?

Web Forms :: The Process Cannot Access The File 'c: Empmy.pdf' Because It Is Being Used By Another Process?

Apr 3, 2010

I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:

FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read);
BinaryReader reader = new BinaryReader(fsr);
byte[] bytes = new byte[fsr.Length];
reader.Read(bytes, 0, bytes.Length);
FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write);
BinaryWriter writer = new BinaryWriter(fsw);
writer.Write(bytes, 0, bytes.Length);
// clean up
writer.Flush();
writer.Close();
writer = null;
fsw.Close();
fsw.Dispose();
fsw = null;
reader.Close();
reader = null;
fsr.Close();
fsr.Dispose();
fsr = null;
Later after sending the email I:
mailMessage.Dispose();
mailMessage = null;
foreach (string fileName in attachments)
{
if (File.Exists(fileName))
File.Delete(fileName);
}

The error occurs at: the File.Delete(fileName);

how I can delete or reopen these files after sending the email?

How To Recognize Whether The Process Is The IIS Worker Process From Within A .NET Code

Dec 25, 2010

Dear ladies and sirs.

I have a .NET infra code running both within the IIS worker process and within a desktop client app. How can the .NET code determine whether it is running within an IIS worker process?

I know that I could check the name of the process (w3wp.exe, for instance), but I would like a more robust approach. I wish to make a side note. This is not a production need. I need this information to enable certain scenarios useful during the development and testing phase. Specifically to ease the testing of secure vs non secure configurations.

C# - Tracking The Process Of A Singleton Process In A Web Application

How do I: Ensure that only a single process is running at a time (i.e. if I refresh the browser, I don't want to start the process a second time)Track progress - there are 4 points of the process (at 25%, 50%, 75%, 100%) that I want to track, and when each part completes, I want to update the progress bar. I have a status object for the running process, but the question is how to update the progress bar automatically? Do I need to use threads to achieve the above two?

Web Forms :: Process Cannot Access The File It Is Being Used By Another Process?

Nov 6, 2010

My code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?

here's the code:

protected void Page_Load(object sender, EventArgs e)
{if (!IsPostBack) // if this is the first time page loads, set k to 1
{ lognewuser();
}}
