You're using this code to load an Excel (*.xls) file into an RTB?? 
Why are you using a RichTextBox at all?? If you're coding is just doing search and replace of text in a file, why are you using a RTB??
I don't know what the point of this code is. First, you say you're doing search and replace in several types of files containing millions of lines of text. Then you say you're writing a Notepad replacement. Which is it?

Good luck saving that back to an .xls file...
You can use either a RTB or a TextBox with the character limit set to -1. You can't improve the performance of the search and replace on huge files. You simply have to pare down the size of the file.

what's that means (Good luck saving that back to an .xls file...)
can u tell
help everyone

It means you created a string of text out of the data in each cell. Sure, you can make changes to the text, but how are you going to save those changes back to an .XLS file??

you choose wrong form. but solution is following
declare following at form level

Microsoft.WindowsMobile.Status.SystemState(Microsoft.WindowsMobile.Status.SystemProperty.Pho<br />
<br />
neCallCalling)
add following code at form load event
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles <br />
<br />
MyBase.Load<br />
<br />
AddHandler callState.Changed, AddressOf callState_changed<br />
<br />
End Sub
and add following procedure
Private Sub callState_changed(ByVal sender As System.Object, ByVal args As <br />
<br />
Microsoft.WindowsMobile.Status.ChangeEventArgs)<br />
<br />
If (Microsoft.WindowsMobile.Status.SystemState.PhoneIncomingCall = True) Then<br />

The Acrobat class copies the PDF to the clipboard as a PDF ?

Don't repost the same question. You posted the same question not more than an hour and half ago.
We do this on a volunteer basis, answering questions on our own time, when we get the time. We don't get paid to do this, you're not paying for support, so you shouldn't expect paid support speed.

:(Hi, I am really struggling to figure out how to add the values in a datagrid column named "Category Ratio". I don't want the "Category Ratio" column total to be less than or higher than 100(it is functioning as a percentage column) and I therefore need to check that the user has set the colun values for each row to add up to 100. Can anybody tell me how to add up the column values. The column is the second column in the datagrid. column 1 = "Category Name" column 2 = "Category Ratio". Thanks

Hi,
Adding the values up is not that difficult, just loop through the rows in the dataset or datatable (not the datagridview) and add up the values. Something like this:
<br />
Dim rw as DataRow<br />
Dim i as Integer 'or double or whatever<br />
For each rw in YourDataSet1.Tables("YourTableName").Rows<br />
If IsDbNull(rw.Item("Category Ratio")) = True Then<br />
i += 0<br />
Else<br />
i += rw.Item("Category Ratio")<br />
End If<br />
Next<br />
What you really need to think about though, is how you want your app to react when the rows do not add up to 100 percent: throw a simple MessageBox and let the user calculate it in his head, reset all values to 100 divided by the number of rows, adjust all values equally, adjust only all values or some, or only one according to certain logic?
Good luck,
Johan
My advice is free, and you may get what you paid for.

 HI..
pls help me to get the system time.. vb.net..

i dont know if pocket pc really applies to what you want....meaning compact framework right?
otherwise, i think with a datetimepicker and a timer control's tick method you can get the timer at every tick even to millisecond
just check the interval property of the tmer control

thanks for the qucik reply..
actualy the thing is i want to extract the time from system..
then later i can convert it to milliseconds anyhow..
the thing is i don't know trhe codings to get the thing..
thanks
regards

ok add a timer control say timer1 to your project
add a datetime picker also
set the timer interval to 1 ( maybe )
on your form load you can put something like
then go to its start method thus
timer1.start (byval......) {
//label to display time on
label3.text=date.now.millisecond
//view the other methods of the date.now, to get what you want
}

Using a timer with an interval less than 15 is pretty pointless. The resolution of the system clock is not higher than that, and also the screen is not updated more often than that.

Hi,
I don't know about PocketPC/Compact Framework, but most approaches that express
time in milliseconds don't have that resolution at all (i.e. the value increments
by 20 or more at once).
You may want to read my "timers" article.

You can't get the system time in milliseconds, because the system clock doesn't have that resolution.
You can use the DateTime.Now property to get the system time. A DataTime value has resolution down to 1/10000 second, so you can display it as milliseconds if you like, although the system clock doesn't have that resolution.
