Hi Rahul,
CSV is for Comma-separated values. CSV files are just like an excel. CSV is mainly use to import/export huge data in SQL. You can notice in some websites "Export to excel" link, if you click this link a file will be downloaded, which will be actually a CSV file (we use CSV due to its fastness and quick response).
Thanks
Be a good professional who shares programming secrets with others.

Well, no not really. A true Excel file (.xls) is not a csv file.

Sometimes.
An Excel file is of a very specific format. A csv file is simply a comma delimited file which can be read by Excel or any number of other applications.
if you type bob,the,coder into notepad and save it you have a csv format file.
Hope this helps

Hi,
I have create a deployment project in Visual Studio 2005. How do I set icon that displays in the Add/Remove program for my application?
Thanks
|
|
|
|
|
Select your Deployment Project > properties > AddRemoveProgramsIcon "the first item in the list"
Then browse for your icon "should be imported first"
All generalizations are wrong, including this one!

If you want one and only one instance of a class then you need to hide the constructor and use a static method or property to return the single instance:
class foo
{
private static foo bar;
private foo()
{
}
public static foo barHandle()
{
if (bar == null)
{
bar = new foo();
}
return bar;
}
}
cake, piece of.
Panic, Chaos, Destruction.
My work here is done.

If form1 and form3 are child forms, you can iterate through form2's MdiChildren to check before opening.

Hi friends,
How can we do off/disable/suspend to the undo of the system
So that action and data would not go to undo stack.
e.i
If undo is off and user write some text in a notepad or delete any file.
Than user could not do undo,since it is not in undo stack.
Any type of help will be appreciated.
Thanks in advance.
Regards,
Khaleek Ahmad

Hi all,
i have athe following Crc16 method. I want to use it in my C# application but am not sure how to go about it. Can anyone please put some light on this issue.
short int crc16(char *pBuf, short int Len, short int InitialCrc){
short unsigned int crc=0, i=0;
crc = 0;
for (i = 0; i < Len; i++ ) {
crc = (crc >> 8) | (crc << 8);
crc = crc ^ *pBuf;
crc = crc ^ ((crc & 0xff) >> 4);
crc = crc ^ (crc << 12);
crc = crc ^ ((crc & 0xff) << 5);
pBuf++;
}
return(crc);
}
Many thanks in advance

First you have to decide how you want to handle the characters. A character in C++ is 8 bits, while a character in C# is 16 bits.
After that, the translation is pretty straight forward.
Despite everything, the person most likely to be fooling you next is yourself.

I am not sure that it is correct, as the result (which should fit in a 16 bit number) overflowed. I have modified it slighty, best would be to test the output with the output of the native function.
static unsafe ushort crc16(char* pBuf, int Len, ushort InitialCrc)
{
ushort crc = InitialCrc;
for (int i = 0; i < Len; i++)
{
crc = (ushort)((crc >> 8) | (crc << 8));
crc = (ushort)(crc ^ *pBuf);
crc = (ushort)(crc ^ ((crc & 0xff) >> 4));
crc = (ushort)(crc ^ (crc << 12));
crc = (ushort)(crc ^ ((crc & 0xff) << 5));
pBuf++;
}
return crc;
}

leppie, thank you very much. It looks perfect according to my previous results done in C++ ... five from me :

You have changed the type from ushort to uint, I'm not sure that works properly.
Do you really want to use unsafe code and pointers? Why not just use a string?
The InitialCrc value isn't used in the method at all, so you should remove it.
ushort crc16(string buffer) {
ushort crc = 0;
foreach (char c in buffer) {
crc = (crc >> 8) | (crc << 8);
crc ^= (ushort)c;
crc ^= (crc & 0xff) >> 4;
crc ^= crc << 12;
crc ^= (crc & 0xff) << 5;
}
return crc;
}

Hi,
kindly let me know that, how may I correct the following problem?
* this connection string works good :
string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\BT.XLS;Extended Properties=""Excel 8.0;HDR=YES;""";
* but this does not work by using textBox1.text :
string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ textBox1.Text +";Extended Properties=""Excel 8.0;HDR=YES;""";
error is : "; expected"
Thank you in advance

Did you try debugging to see what is the actual value of ConnectionString after assignment?
|

He can't debug it as it doesn't compile.
