Just put a try/catch block around everything that could fail, and there you have it.

Streamreader, Stringbuilder, and Stream or Stringwriter

I have done plenty of googling and have gotten close to a solution but wanted to make sure I'm going about it the right way.

I have a data file which is a non delimited fixed field position file that has missing data. I basically want to read each line in and determine if a certain field is blank. If so I use another field in that same record to retrieve the missing data from the database. After getting the missing value I would like to use StreamWriter or StringWriter (not sure which) to write out each line to a new file with the updated field value.

Appreciate any advice you all may have on this subject.

Thanks,
Jason

I would advice you to do the following:

1. Open the input file
2. Open the output file and create StreamWriter for it
3. Read data line-by-line, and for each line do the check and write to the output file

You need StreamWriter.

The difference:
StreamWriter allows you to write contents to any stream: file, socket, etc;
Stream represents writeable file, socket or other stream (this can be also a memory, or string) - it's not convenient to write strings to stream, that's why you need StreamWriter.
StringWriter writes all contents to a string (in memory);
StringBuilder allows you quickly build string from parts; you needn't it here

Thanks for the steps and showing the difference between the different classes. Below is what I have so far and I think it will work. My new file contained the 111222333 string for all the missing data which was the desired result.

Thanks,

Jason

StreamReader sr = File.OpenText("C:\\Source.txt");

StreamWriter sw = File.CreateText("C:\\Test1.txt");

while (sr.Peek() != -1)
{
string strRecord = sr.ReadLine();
string strSurname = strRecord.Substring(0, 10);
string strFirstName = strRecord.Substring(11, 8);
string strPupilNum = strRecord.Substring(20, 9).Trim();
string strSSID = strRecord.Substring(373, 9).Trim();

if (strPupilNum == String.Empty)
{
// call db stored procedure to retrieve PupilNum based on SSID
StringBuilder sb = new StringBuilder(strRecord);
sb.Remove(20, 9);
sb.Insert(20, "111222333", 1);

strRecord = sb.ToString();

}

sw.WriteLine(strRecord);

} sw.Close();

Yeah, that's it.
Don't forget to dispose your StreamWriter and StreamReader.

Working with the animation codes in C#

I am currently working on a simple game for the children in C# WPF. It uses the simple animation from Expression Blend. All that is done is a simple textblock falls in the apps and I wish to make a loop of it such that everytime the loops restarts that is the textblock falls the new contents are displayed to it. XML and LINQ to XML is what I plan to use.

The real problem is the storyboard codes are in XAML and it needs to be looped and added new features from the C# codes. I seem to have no idea how to accomplish that.

I would be grateful if anyone could help. Any favors will be appreciated.Than you in advance.

Hi There

I am using Aspose.pdf to generate pdf documents.
The pdf document contains a table which is populated with data from a database.
I have the problem that if the table needs to continue to the next page, the pdf does not generate.

Is there any code that I need to include to allow the document to continue to a new page?

Regards,

hi,

you can use itextSharp.dll to generate pdfs ,this will get from sourceforge.net , and reference to your project , then write code like this

Document dc = new Document(PageSize.LETTER);
dc.NewPage();

Hello everybody,

I have a file where some application is storing some values. I want to access to this file in read mode but when I try to open the file I have always the message that the process can't acces the file because it is being used by other application.

If I try to open this file with Microsoft excel I have an alert that says that the file is user by other application but I am allowed to open the file in read mode only.

How can I access the file with .net and advoid the exception if it is possible?

Thanks in advance

Try this:

FileInfo file = new FileInfo(ConfigurationSettings.AppSettings["FilePath"]);
            using (FileStream fStream = file.Open(FileMode.Open, FileAccess.Read, FileShare.Read))
            {
