I had expected you would use what I provided to get the basic information, then once you know the operation from that, use an operation-specific regex to parse the data.

What's not working as you want/expect or what errors are you getting and on which lines?

You may use Directory.GetFiles(dirname) to get all the files from dirname location. Then loop through returned files and call your code.

something like this, you should review it because you know what exactly to read from console,...:
...
foreach(string inFile in Directory.GetFiles(filePath))
{
...
StreamReader sr = File.OpenText(inFile);
line = sr.ReadLine();
Console.WriteLine();
Console.WriteLine("Successful file open!...");
Console.WriteLine();
Console.WriteLine("Input file name to save!");
Console.WriteLine("sample: d:\\filename.txt");
filePath = Console.ReadLine();
FileStream file = new FileStream(filePath, FileMode.Create);
StreamWriter sw = new StreamWriter(file);
List lines = new List();
while ((line = sr.ReadLine()) != null)
{
lines.Add(line);
}
try
{
int numberOne = Int32.Parse(lines[0]);
int numberTwo = Int32.Parse(lines[1]);
int numberThree = Int32.Parse(lines[2]);
int x = numberOne + numberTwo + numberThree;
sw.WriteLine(x);
}
catch { }
sw.Close();
sr.Close();
}

Error:<br />
A local variable named 'inFile' cannot be declared in this scope because it would give a different meaning to 'inFile', which is already used in a 'parent or current' scope to denote something else <br />

Of course...you had to remove first inFile line, because now you are not reading the input file from console.
I just sent you the main idea about how the cose should be changed. Its your task to finish it.

Hi guys,
I have a winform with a public datagridview(dgv1) with some combobox columns.
from a another form i can see the dgv1, but not the columns that i have created into it.
What's that means?
Thanks

Make sure you have GenerateMember = true and Modifiers = Public for each column.

Hi,
I want to write a Sharepoint web service that will run on my Windows Server 2003 as that's what Sharepoint will run on.
I want to write the WS on my local machine which is running VS 2005 on XP and then deploy it to my server. It seems that I need to reference the Sharepoint assembly in my project but I can't install Sharepoint Services 3.0 on my XP machine can I? And that means I can't install the VS 2005 extensions for Sharepoint either.
Do I *have* to do my development on the server itself or what? I'd rather not have to install VS 2K5 on the server just to write one simple WS.
|

You can use the sharepoint webservices instead of the object model, or develop on a server OS. You can't use the sp object model on XP.
I didn't get any requirements for the signature
|
|
|
|
|
Thanks for your reply
I can just reference the web service on the server then?
My server is running as a VM on the same machine with a bridged network.
How can I include the following in my project then?
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
|

DUDE! You can't show people where the documentation is, it's a secret! Imagine what would happen to these and other forums if developers started using Google to find and then read documentation!
|
|

|

Shut it you! I'm gonna join your geeky club if it kills me 
|

|

|

Thanks - I'm trying to follow an example in a book and I was dreading what it meant, that I'd have to install VS2K5 on the OS VM 
Ah well

Hi, i have two function:
long ImageFileOpen (long *hImageFile, char *szFileName, long bWrite)
Parameters:
hImageFile
Image file handle is returned here.
szFileName
File name of the image file.
bWrite
0 = open file for reading, 1 = open file for writing.
and
long ImageFileRead(long hImageFile, long *hImage)
Parameters:
hImageFile
Image file handle that was created by previous call to ImageFileOpen.
hImage
Image handle of a new image is returned here.
i have called them in this way:
[DllImport("xxx.dll")]
unsafe public static extern long ImageFileOpen(long* hImageFile, [MarshalAs(UnmanagedType.LPStr)] StringBuilder szFileName, long bWrite);
[DllImport("xxx.dll")]
unsafe public static extern long ImageFileRead(long hImageFile, long* hImage);
and then with:
long hImageFile=0;
long hImage=0;
StringBuilder fullname = new StringBuilder(@"c:\xxx.tif");
rc = ImageFileOpen(&hImageFile, fullname, 0);
rc = ImageFileRead(hImageFile, &hImage);
...but at ImageFileRead the compiler says "System.AccessViolationException".
why? thank you very much...I need help...

Hi,
I would try that differently:
1.
in this situation there is no need for pointers and unsafe keyword, just use the IntPtr class (it takes 4 or 8 bytes depending on Win32/Win64).
2.
read-only strings can be passed to a char* as is; a StringBuilder is required only if the native code needs to provide or modify the string value (use a StringBuilder.ToString when done).
3.
an output parameter needs the out (or ref) keyword; that basically takes care of the indirection,
i.e. the variable gets then passed by reference automatically.
4.
warning: in C# long takes 8 bytes, in the native world long usually is 4 B.
So I would try this:
[DllImport("xxx.dll")]
public static extern long ImageFileOpen(out IntPtr hImageFile, string szFileName, bool bWrite);
[DllImport("xxx.dll")]
public static extern long ImageFileRead(IntPtr hImageFile, out IntPtr hImage);
IntPtr hImageFile;
IntPtr hImage;
rc = ImageFileOpen(out hImageFile, fullname, false);
if (rc...) ...
rc = ImageFileRead(hImageFile, out hImage);
Now the tricky part could be what comes next: how will managed code access the content of the image?

ty very much Luc....it's work.....
so the problem was the indirection? And the out takes care of it? So i don't have to use a fixed *.
