Dear Developers,
I'm importing CSV file to sql DB using ASP.net. It works fine. But ,If a Cell contain a value like john,inc. CSV take it as two values as john and inc
But i want in a single value as john,inc .. How can i do thatThanks in Regards,
Prajin

|

For this kind of value you have to use ' or " to enclose the Value
Ex// 1,'john,store',aroda

Hi Chetan,
This did not work when I read "1,'john,store',aroda" from file and split it on comma to convert to a datatable, "john" and "store" are coming in different columns. I want this in same column.

Prajin

Can u please post the code??

try
{
memStream = new MemoryStream(fileImport.FileBytes);
reader = new StreamReader((Stream)memStream);
int nCurrPosition = 0;
int nNoOfCharactersToBeRead = Convert.ToInt32(reader.BaseStream.Length) - nCurrPosition;
szRawString = "";
if (nNoOfCharactersToBeRead >= 0)
{
reader.BaseStream.Seek(0, SeekOrigin.Begin);
char[] vBuffer = new char[nNoOfCharactersToBeRead];
reader.Read(vBuffer, 0, nNoOfCharactersToBeRead);
if (vBuffer.Length != 0)
{
szRawString = ReArrangeStringEx(vBuffer);
}
}
if (szRawString != "")
{
szRawString = szRawString.Replace("\r", "");
string[] rows = szRawString.Split("\n".ToCharArray());
for (int j = 0; j < rows.Length; j++)
{
string[] columns = rows[j].Split(',');
if (dtCustomer.Columns.Count == columns.Length)
{
dtCustomer.Rows.Add(columns);
}
}
}
reader.Close();
memStream.Close();

Well you're not operating on this as a CSV (which would honour the quotes as a text identifier) - you're simply splitting the string using comma:
string[] columns = rows[j].Split(',');
If you want to roll your own code to read from a CSV then you'll need to build something into this line above that honours quotes as a text identifier.
|
|
|
|
|
I suppose u first split your string by ' and then split it by comma. Hope it works.
|
|
|
|
|
for (int j = 0; j < rows.Length; j++)
{
string[] columns = rows[j].Split(',');
if (dtCustomer.Columns.Count == columns.Length)
{
dtCustomer.Rows.Add(columns);
}
}
change your code like this
arrTemp[]=rows[j].Split("'")
you get three parts
1,'abc,def',asd
as 1,
abc,def
,asd
now
add this like this
for (int j = 0; j < rows.Length; j++)
{
arrTemp[]=rows[j].Split("'")
dtCustomer.Rows.Add(arrTemp[0].subString(1,arrTemp[0].Length-1);
dtCustomer.Rows.Add(arrTemp[1]);
dtCustomer.Rows.Add(arrTemp[2].subString(2);
}

Hi All,
I have a GridView in which all the column are template Column that contain textbox as a item Template. I have defined textChanged event for textboxes.
I have made these textbox as AutopostBack as true so that if I make any change in this textbox I can get that change in code behind file.(I wan to do with code behind file only no JavaScript)
Now if I edit any textbox which is inside the Gridview Problem lies here if I edit the textbox ,the textbox event for that textbox is called as many as time as there are number of rows in gridview and moreover it happen only when I edit the textbox for firsttime after that it execute only for only once .
So if someone has met with this problem pls do update me .

Hello everyone,
This is developed in .Net 2.0 (ASP .NET with VB .NET as code)
In a page, I have 9 fields for user to upload files. I have just encountered a situation where I choose a file for all the fields (that means 9 files), and when the total sum of file size (of the 9 files) exceeds a certain amount, the next page that I see after I click on submit is "Page cannot be displayed".
When I choose the 9 files with smaller size, the system works just fine.
Do you have any idea if there is such a limitation on the file size to be uploaded in a form? If there is, what is the size?
Appreciate your help.
Thanks,
Yenyen

That's becuase you are going beyond default maximum size that request can have you need to make it more in Web.config
httpRuntime maxRequestLength="100000" add this in system.web tag
Thanks and Regards

I am currently developing an AJAX enabled calendar
i have a back and forward button that scrolls through the month of the year
A global variable called currentDate is set during the first load, and and it will be changed by the event handler for the back and forward buttons
however, right now for some reason, the global variable resets itself to the declared default value automatically every time i press the back/foward button.
I think i am doing something wrong the updatepanels and stuff
I wrote the calander, the back and forth button in a control and then i place the control in a updatepanel in the actual page.
It seems like that the control is being re-created everytime i press the button?
can someone help!?
