View 3 RepliesC# Split Function - Splitting String Delimited Files
Jun 19, 2010I am having problems with the .split function.
token_list = line.Split(',');
My input data is a CSV file that contains numbers and strings totaling 5 columns. The strings are string delimited...
1, 2, "Test", 1, "Test" 5 columns
1, 2, "Test", 1, "Test" 5 columns
1, 2, "Test, Test", 1, "Test" 6 columns!!
1, 2, "Test", 1, "Test" 5 columns
The split function as it is written above is splitting the third line into 6 columns because there is a comma in the data. Is there a way for me to tell the split function to ignore commas in strings?

View 2 RepliesAn Export-to-Excel Function Can Be Scalable?
May 3, 2010Summary: ASP.Net website with a couple hundred users. Data is exported to Excel files which can be relatively large (~5 MB).
In the pilot phase (just a few users), we are already seeing occasional errors on the server in the exporting method.
Here's the stack trace:
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --->
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at
System.IO.MemoryStream.set_Capacity(Int32 value) at
System.IO.MemoryStream.EnsureCapacity(Int32 value) at
Even aside from this particular problem, in general exporting to Excel requires the instantiation of huge Excel objects on the server for each request, which I've always assumed to mean disqualifies Excel for "serious" work on a highly-loaded server. Is there any general way to export to Excel in a "light-weight" manner? Would simply streaming the data into a CSV file work for this?

How To Save .xls Changes From Excel Function After Updating / Modifying It Using OleDbCommands
Mar 28, 2011I have an .xls file that I am allowing a user to make changes to by entering values in TextBoxs within a GridView. In the excel file, there is a column (D) that does a basic (=C4-B4) function. The user is allowed to edit both the B and C columns, but not the one containing the function (D). I am using OleDbCommands to make changes to the .xls file, and that works fine. However, column D is not being updated. I have to physically open the excel file, then save it for the function column to be properly updated. What would be the easiest way to make sure the function is "run" and saved when changes to the source columns are made?
Edit Well, merely hiding the modalpopupextender that it is in saves the file. But I still have the problem of column D not being updated client-side. I assume that's something I'll have to do myself?

Web Forms :: Use Stringbuilder When Concatenating More Than 2 Strings - Performance?
Jul 2, 2010I have been led to believe that the performance benefits of using StringBuilder over normal concatenation means that you should always use stringbuilder when concatenating more than 2 strings. However when I test them this does not seem to be the case. Take these 2 methods
public void TestMethod5()
{
for (int i = 0; i < 1000; i++)
{
string t = string.Empty;
t = "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd"; ;
}
}
public void TestMethod6()
{
for (int i = 0; i < 1000; i++)
{
StringBuilder sb = new StringBuilder();
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
string t = string.Empty;
t = sb.ToString();
}
}
TestMethod5 takes 0.03 milliseconds so complete but TestMethod6 takes 1.43 milliseconds What is going on?

Web Forms :: Export To Excel Function Errors When Trying To Render The Grid For The Export?
Apr 27, 2010I have a web form that contains a GridView, which impliments Search in Grid with a TextBox and Button control in the footer. This works as I have it now. I have also implimented a Export to Excel function. The Export to Excel works by itself if the Search in Grid function is not included in the footer.The Export to Excel function errors when trying to render the Grid for the export. Is there a better way to incorporate both functions and accomplish the same thing? Am I missing something simple?

StringWriter SW = new StringWriter(SB);

Web Forms :: String And StringBuilder - Any Change Updates Memory Location Rather Creating New
Oct 19, 2010String is immutable and StringBuilder is mutable. So if I change the value of a string a new memory created with the new value, whereas in StringBuilder it updates its memory location rather than creating a new memory location. So for large concatenation stringBuilders are preffered. But when I create a new String object, a fixed memory is created. And any changes will update its memory location, rather than creating a new memory location.
For e.g.
String s = new String();
s = String.Empty;
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s =string.Concat(s, "test" + i.ToString()); ///This is effecient compared to previous step
}
Now instead of String class I will use a StringBuilder class.
StringBuilder s = new StringBuilder(String.Empty);
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s.append( "test" + i.ToString());
}
