Visual Studio :: Writing C Source Files Using VS IDE?

Apr 5, 2010

I am having difficulty using C in the VS IDE. No matter what I write the code always has errors and I am not able to see the end result. I don't understand VS and being that I am supposed to be taking Programming in C as a class, it is hard for me to get my work done because I don't understand VS and I really don't know how to match the two up.

Databases :: Creating, Opening, Writing To Excel Files?

Aug 5, 2010

I am creating an site where a user uploads an excel file to check if any of the records exist in a database. Then they are returned an excel file with only the records that are NOT in the database.
I was thinking I should do it this way1. User uploads their excel file. The app opens excel file and loads records into a dataset (so far this is working with the code below)2. Using datarow and another function to check if each excel record exists in the database3 If the record does NOT exist, and it is the first record tested, create an excel file called records.xlsx and write the record into the file

4. Check the next record and if it does NOT exist in the database, then check if records.xlsx already exists then open it and write it into it.

[Code]....

Hopefully its clear, sorry if its not, I'm a bit of a novice at this. Is this a good way to do it? Does anyone know of any tutorials that might outline how to open an existing file and write to it?

Post Back Does Not Work After Writing Files To Response?

Feb 25, 2010

What I have?I have a ASP.NET page which allows the user to download file a on a button click. User can select the file he wants from a list of available files (RadioButtonList) and clicks on download button to download it. (I should not provide link for each file that can be downloaded - this is the requirement).What I want?I want the user to download multiple files one by one by selecting the required radio button and clicking on the button.What problem am I facing?I can download the file for the first time properly. But, after downloading, if I select some other file and click on the button to download it, click event of the button does not post back and the second file will not be downloaded.I use the follwoing code on the button click event:

protected void btnDownload_Click(object sender, EventArgs e)
{
string viewXml = exporter.Export();
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=views.cov");
Response.AddHeader("Content-Length", viewXml.Length.ToString());
Response.ContentType = "text/plain";
Response.Write(viewXml);
Response.End();
}

SQL Server :: Storing Files In A SQL Database?

Aug 16, 2010

Have a question about the best approach for file storage in a SQL database. I have a table called Widgets, and each row in the Widgets table can have multiple files. I also have another table called Extensions, and again each record in this table can have many files.

Here is what I am considering:

Approach #1:

[Code]....

That approach is very simple and easy to use, but I feel that I could merge the two file tables into one, then use lookup tables:

Approach #2:

[Code]....

The thing is, there are no duplicate or shared files between the two types of objects. So even though I feel better about approach #2, I am concerned that I may be adding additional complexity (and using more server resources to perform the joins), than needed.

It works now! I replaces all Run methods in the Student class with DB.Run

But I want to know if it will work fine with a lot of people online, not me only. I'm not sure how static things work with ASP.NET, maybe it'll eat a lot of memory?..

Security Exception Over Reading/writing Files On Medium Trust?

Nov 21, 2010

I'm working on a project in ASP.Net, and it requires reading/writing to files on my server. I'm hosted at GoDaddy, and they swear they've got me at Medium Trust. When I try to read or write files that are in my own domain, I get Security Exceptions. I've tried multiple ways of opening/saving the files and they all return security errors. Here's the most recent error and offending line of code (I didn't save them all, they're all pretty much the same thing):

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed.

PngBitmapEncoder pbe = new PngBitmapEncoder();
pbe.Frames.Add(BitmapFrame.Create(new Uri("ornament.png", UriKind.Relative))); <-- Error

I've also gotten the error when trying to read/write using FileStream, Bitmap.Save and new Bitmap("ornament.png"). Could there be a problem with my Web.config? Is read/write supposed to be blocked by medium trust? This is a time-sensitive project and this is a brick wall for me. The deadline is end of business day tomorrow and GoDaddy isn't responding.

Storing PDF Files As Binary Objects In SQL Server?

Feb 27, 2010

I have to find a design decision for the following task: I have a SQL Server database and it contains a table of orders. PDF documents will be uploaded by users through a simple file upload from a web page and assigned to an order. There is not more than one document per order (perhaps no document, never more than one). For this purpose a user opens a web page, enters an order number, gets the order displayed and clicks on an upload button. So I know to which order the uploaded document belongs to.

Now I am considering two options to store the documents on the web server:

1) Extend my table of orders by a varbinary(MAX) column and store the PDF document directly into that binary field.

2) Save the PDF file in a specific folder on disk and give it a unique name related to the order (for instance my order number which is a primary key in the database, or a GUID which I could store in an additional column of the order table). Perhaps I have to store the files in subfolders, one per month, and store the subfolder name into the order row in the database, to avoid getting too many thousand files in one folder.

After the PDF files are stored they can be downloaded and viewed via browser after entering the related order number.

I'm tending towards option (1) because the data management seems easier to me having all relevant data in one database. But I am a bit afraid that I could encounter performance issues over time since my database size will grow much faster than with solution (2). Around 90% or even 95% of the total database size would be made up only by those stored PDF files.

Here is some additional information:

The PDF files will have a size of around 100 Kilobyte each
Around 1500 orders/PDF files per month
Windows Server 2008 R2 / IIS 7.5
SQL Server 2008 SP1 Express
Not quite sure about the hardware, I believe one QuadCore Proc. and 4 GB RAM
Application is written in ASP.NET Webforms 3.5 SP1

(I am aware that I will reach the 4GB-limit of the SQL Server Express edition after around 2 years with the numbers above. But we can disregard this here, either removing old data from the database or upgrading to a full license will be a possible option.)

My question is: What are the Pro and Contras of the options and what would you recommend? Perhaps someone had a similar task and can report about his experience.

Crystal Reports :: Storing Multiple Data Types In A Class?

Aug 31, 2010

I need help writing a class that will contain three values per item. I'll be passing parameters to a report: Parameter Name, Data type (int, string, date, etc), and Value. When I pass those values to the report using the class they should be in original form (i.e. an integer should be a numeric, a string should be a string, etc.).


I can do it converting the data's value to strings on one end, and reconverting to the original data type on the other, which seems like a lot of runaround. Is there a simple way? Also, if I'm able to store & retrieve the data in it's native format I don't need the "Data type" stored.

DataSource Controls :: Storing Large Files In Database?

Aug 6, 2010

I want to upload some large files from a web page to MS SQL Sever database, I am very sure that it is sounding weird.

File sizes are around 100MB.

I am having following settings,

SessionTimeOut period = 60 Mins,

Server Operation timeout = 60 Mins,

SQL Connection Timeout = 4 mins (Not sure if this is helping)

This is page is going to be used by our client only once a week & as they are having web farm environment we are avpiding to store these files on file systems.

Currenty we are able to upload files with sizes upto 8 MB succesfully. But when we are uploading a file of 100MB it fails, its for sure that operation takes lots of time.

C# - Clean Conflicting Class Files From Temporary Files

Apr 21, 2010

Class file Conflicts in C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files is preventing me from building the solution. Even though I try emptying out the folder, each time Visual Studio starts the build process, it brings in the class file in to the temp folder with the same folder name. If I restart the machine or leave it overnight, project build without error. Is there anyway to tell Visual studio to delete/ignore/clean any lingering class files that could be in the temp folder?

Clean solution option in VS doesn't work either. Class file in conflict are from the App_Code folder.

I have hosted a website in Client's Server.

One of the functionality of the site is to create a PDF File on a Specific Shared Path.

The Shared path is mentioned in the Web.Config File.

If the given shared path exists in the same machine then the PDF File is created and stored in the shared path.
