The problem is:
By using late binding call the TransferSpreadSheet metod with arguments (acExport, default, "querryname", "querryname.xls",default,default)
The question is:
How can i get acExport constant of AcDataTransferType an how should i transfer it to TransferSpreadSheet call method?
Parameters = new Object[5];
Parameters[0] = ???!
Parameters[1] = Type.Missing;
Parameters[2] = "querryname";
Parameters[3] = AppPath + "\\querryname.xls";
objDoCmd_Late.GetType().InvokeMember("TransferSpreadsheet", BindingFlags.InvokeMethod,
null, objDoCmd_Late,Parameters);
Advice needed.

I just want to know if its possible to include the double quotation marks ("") as one of regex delimiters?
If it is possible, how will i be able to include it? Because whenever i include one, it always terminates the pattern string.
Then if it's not possible, is/are there any alternatives ways so i can make the double quotes as delimiters?

I'm so bad with RegEx, everytime I want to use them I need that[^]!

That link that you gave me may help me alot since i don't know how to create a regex pattern for matching strings...ehehehe..

It works fine for me - are you sure you aren't mistaking " as a string terminator for it terminating the regex?
string s = "hello \"x\"there\"x\" it \"works\"";
Regex r = new Regex("\"x\"");
string y = r.Replace(s, "!");
gives y = hello !there! it "works"

would it be ok to do it with you sql statement.
In that case you could do:
Select name, adress, age / 2 as age
from [yourdbname]
|
|

|

Thank you for you reply .....But i had a problem when i going to DataBind.
this is the error..
GridView1.DataBind(); //------ error - A field or property with the name 'age' was not found on the selected data.
But i correctly configured on GridView1.I use a BoundField to view this 'age' with DataField='age'on my GridView1 control..
Why i got this error..????

You can create new coloum that age value is divied by 2, and delete the old age column and set the new column's name to "age"
|

You can change it very easily
suppose you have the dataset ds
Then
ds.Tables[0].rows[2].columns[2]="Your New Value";
Thank you

Hello,
I have a bound DataGridView with one of the columns bound to a date field. If date is entered as 31-08-2009 everything works fine, but user wants to fill in the date as 31082009 (European format).
On the cell leave event I have:
if (this.dgvInvoice.Columns[e.ColumnIndex].Name == "DateColumn")
{
string DateText = this.dgvInvoice.Rows[e.RowIndex].Cells["DateColumn"].EditedFormattedValue.ToString();
try
{
this.dgvInvoice.Rows[e.RowIndex].Cells["DateColumn"].Value =
customfunction(DateText);
}
catch
{
this.dgvInvoice.Rows[e.RowIndex].Cells["DateColumn"].Value = DateTime.Today;
}
}
}
The customfunction returns a date like 31-08-2009. The try goes well, but still I have an exception that it's not a valid DateTime.
The EditedFormattedValue is not writeable, and after I set the Value, the EditedFormattedValue is still the same.
How can I solve this ?
Thanks in advance.

Hi Rob!
It seems you use CellLeave event of the grid and alter leaving the event logic the value not always updates correctly.This event is fired when cell lose its focus,not when it was edited by the user.You would better use CellEndEdit event.
|
|
|
|
|
Alas, the exception about a bad date is thrown before the endedit event is raised.
Any other suggestions ?
Thanks,
Rob

What kind of DataSource are you using for your grid?
Is it DataTable or someone else?
|
|
|
|
|
It's a datatable. The specific column is a date field in the datatable.

I think this have to solve your problem :
private void Grid_CellParsing(object sender, DataGridViewCellParsingEventArgs e)
{
if (this.dgvInvoice.Columns[e.ColumnIndex].Name == "DateColumn")
{
try
{
e.Value=customfunction(e.Value);
}
catch
{
e.Value = DateTime.Today;
}
}
e.ParsingApplied = true;
}
Cheers!

Thanks for your efforts, I gave a thumbs up.
Unfortunately the parse event didn't give the desired results either.
I've solved the problem by making an extra unbound text column, hiding the date column, and on the validating event from the new unbound text column the hidden "real" date column is filled.
It's not pretty but it works.

To test the events, I tried the dataerror event, but with no luck, I can catch the exception (which is ugly), but the value doesn't write through to the EditedFormattedValue.
so still looking for a solution.

Consider that there are two files named file1.txt and file2.txt.
file1.txt consists 50lines
file2.txt consists 50lines
Now I want to compare the text of two files taht to line by line,
I mean How can I compare 1st line of file1.txt with 1st line of file2.txt
similarly 2nd line of file1.txt with 2nd line of file2.txt, etc., till the last line
|
|
|
|
|
string[] file1 = File.ReadAllLines("file1.txt");
string[] file2 = File.ReadAllLines("file2.txt");
then use "for" to go through the array and compare it.

You have to use StreamReader
Suppose you have Two streamreader objects
sr1 and sr2
while((str1=sr1.ReadLine())!="" &&(str2=sr2.ReadLine()))
{
if(str1!=str2)
//The Files Are different...
