I am new to the .NET framework, but have a lot of experience with C++ and MFC. I need to do a simple thing. I am using a StreamReader to read lines of text from an ASCII file. I then need to do formatted reads on the Strings^s I get. That is, I want to read substrings, integers, floats, etc, from each line. I guess I could convert the String to a char array and use sscanf(), but that seems dumb.
I can't find any documentation on how to do this. Help!
By the way, are there any good books on C++ .NET that go over the class library ...
Thanks in advance,
Tom

Wy not use normal c++ stream operations or fscanf to parse the file and then convert the results to .Net String's?
System.IO.Path.IsPathRooted() does not behave as I would expect

The only reason I haven't done that is that I thought there must be some .NET way to do it directly on the Strings, and I wanted to learn it.. (I don't have a deadline!)
Thanks,
Tom

Well, I've found an answer that is workable and uses only Strings. There is a method String.Split() that lets one split the String into pieces - I use white space for the delimiter, and that gets me what I need without resorting to 'old' coding practices!
Thanks,
Tom

Never heard of it. I know what COM is, where did you hear it ?

Do you possibly mean CodeDOM[^]?

CodeDOM stands for code document object model. It's basically set of classes and interfaces describing structure of source code. You can read more on MSDN.

Yep, it's Saturday here.
Truth is, I do 40 hours a week for CP, and I work every evening and through the weekends on other stuff. So long as I am working, I am online, keeping an eye on CP and looking for questions to answer. I work from home, CP is also my social life.

Ok. Then other than that 40 hrs will be hell for us. Specially for me. Because I ask the questions for which nobody will(may be can I dont know) answer. Most of the times I got replies from you. If not from Pete. Few times from others too. Thank you for all those replies. And Salam too.

I have a REmote Object as given Below
Public Class ClsFixRem
Inherits MarshalByRefObject
Public Delegate Sub EventHlndr(ByVal ObjOrderMsg As ClsFixRem.OrderMsg)
Public Event Evnt As EventHlndr
Public Function MessageSend(ByVal Ds As DataSet) As String
Dim Objmsg As New OrderMsg
Objmsg.OrderNo = "470"
RaiseEvent Evnt(Objmsg)
End Function
End Class
I have a Server Exe Hosting the REmote Object as given Below. It is a winform app.
Dim channel As New Tcp.TcpChannel(8085)
Dim r As New RemLib.ClsFixRem
RemotingConfiguration.RegisterWellKnownServiceType
("RemLib.ClsFixRem, Remlib", "RemLib.ClsFixRem",
WellKnownObjectMode.Singleton)
Obj1 = New RemLib.ClsFixRem
AddHandler Obj1.Evnt, AddressOf handlevent
Event Handler in Server.exe
Public Sub handlevent(ByVal ObjOrderMsg As RemLib.ClsFixRem.OrderMsg)
MsgBox("handleevent")
End Sub
Client.exe
===========
It is asp.net web application.
If ChannelServices.RegisteredChannels.Length = 0 Then
ChannelServices.RegisterChannel(chnl)
End If
Objrelib = CType(Activator.GetObject
("RemLib.ClsFixRem,Remlib",
"tcp://localhost:8085/RemLib.ClsFixRem"),
RemLib.ClsFixRem)
s = Nothing
Dim str As String
str = Objrelib.MessageSend(dsTemp)
=========
The server.exe is connected to a third system thru a tcp socket. the socket connection is opened when the server.exe starts. the connection should be kept open.
When the client activate the remote object (Remlib) and call the method MessageSend. it should fire the EVent which is handled on the server Exe. in this event handler on the server.exe sends data to the socket and it awaits the response from the third system.
The client of the application is a asp.net web application.
Now when the MessageSend method on the Remote object (Remlib) is called from the asp.net application the event handler on the server.exe is not getting handled.
and because of this i could not send the message to the socket.
Can you give a solution for this.
Regards

I need to convert some text into an integer array. How do I go about doing this?

A lookup table, I guess.

String[] text=originalText.Split(" ");
int[] intArray=new int[text.length];
for(int i=0;i<text.length;i++)
intArray[i]=Convert.toInt32(text[i]);

That depends on what the text contains and how you want to convert it. Do you want to convert each character to it's character code, or does the text contain the textual representation of numbers in any form, that you want to parse?
Does you text look something like this?
"123, 4, 18, 4, 11, 93"
Or something like this?
"123-4-18-4-11-93"
Or something like this?
"4A 10 f8 fe 08 0f"
Or something like this?
"4A10f8fe080f"
Or something like this?
"007, 053, 016, 024, 004, 103"
Or something like this?
"Hello world!"

Thank you everyone for your help. I actually meant to post this message in the vb.net section. I hadn't had to do this conversion in a long time so I forgot the function for doing it. I just rememebered today the asc() function in vb.net does this. Although I'm not sure if it would work for any unicode characters.
I'll also try a vb form of the c code you gave me Thomas. That might work if I ever have to deal with a unicode character.
I appreciate everyones help,
Mike

The Asc function will work just fine with Unicode characters, despite it's name. ASCII was brand new when BASIC was created back in 1963, but now it's kind of outdated...
You should move on into the .NET world, though, and just convert the character to an integer as Thomas suggested. That's what the Asc function does anyway, it's just a wrapper for the real .NET method.

The code I wrote was written in Visual C# so it should be easier to convert to VB than if it was in C (which I don't even know  ). The code is also is not specific to unicode characters. The Convert.toInt32(Object obj) is a standard method in the .NET framework.

What about this:
Int32 x = Int32.Parse(string);

In DataGridView, I'm wanting to create a column of buttons with bitmap faces instead of text. No sweat doing the buttons using DataGridViewButtonColumn. However, I've not found a simple way to put a bitmap or icon on the button face. Anyone done this?
