I'm a bit new to Regex, and almost got this working, except for a small glitch. I have a string called entityName which looks like "120 PP (V987) XYZ", from which I have to strip out the entity code which in this case is (V987). The entity code is V or C followed by any number of digits, all of which is enclosed in ().
My code looks like this:
string[] entityNameString;
Regex regex = new Regex(@"^(.*)(\([V,C]\d+\))(.*)");
entityNameString = regex.Split(entityName);
Console.WriteLine(entityName);
foreach(string s in entityNameString)
{
Console.WriteLine("\t" + s + "\t\t" + s.Length);
}
Unfortunately, when I run it, the output produced is
120 PP (C987) ERT
0
120 PP 7
(C987) 6
ERT 4
0
It produces an extra null string at the beginning and the end. I'm guessing my Regex pattern is incomplete. How should I correct this?
Thanks in advance. 
Cheers,
Vikram.

That is because you are splitting on pattern that matches the entire string.
Let's go for a simple example: If you have a pattern like "(ell)" and split the string "hello" using that pattern, you will get three strings; "h", "ell" and "o". If you have a pattern like "(hello)" and split the string "hello", you will also get three strings; "", "hello" and "".
Make the pattern match only the "(C987)" part of the string, and you get only three strings in the result.

It really doesn't look like you actually want to be splitting the string at all.
if you try this:-
Regex regex = new Regex(@"^(.*)(\([V,C]\d+\))(.*)");
Match m = regex.Match(entityName);
if (m.IsMatch)
Console.WriteLine( m.Groups[2].Value);
Furthermore, your regular expression could be optimised a little - many of the brackets are unnecessary:-
^.*(\([VC]\d+\)).* should work also. Note the the submatch group number as used in my above code will be 1 for this pattern.
And if you move your submatch brackets a bit, like this,
^.*\(([VC]\d+)\).* then your submatch for the string "120 PP (C987) ERT" will contain "C987". I am of course making a wild assumption here that you don't want the brackets in the output.
Incidentally, I didn't test the above code or patterns, but they're good in substance even if they have minor errors in.

Hi!
The only way I've found for this so far is to use the clipboard.
Paste your RTF to the clipboard (probably saving the clipboard contents before doing so) and then call Paste on the Selection object you want your RTF to appear in.
Afterwards restore the clipboard contents.
If anyone has a better solution, I'd be interested in that, too.
Regards,
mav

My advice would have been to go into "Customize Toolbox" and look for "Microsoft Word" component under the "COM Components tab. But looking there, I see that Word has not been included. Apparently, Microsoft does not want us to have this feature?

Hello,
Right now I am using the following code to open a directory for exploring.
I do believe there must be some one line code available to do the same task. If it is true, then would you please let me know.
The code I am using.
Process openFolder = new Process();
openFolder.StartInfo.FileName = Application.StartupPath + @"\User Files\Email Attachments";
openFolder.StartInfo.CreateNoWindow = false;
openFolder.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
openFolder.StartInfo.UseShellExecute = true;
openFolder.Start();

I'm not sure exactly what you are wanting to do here...however if all you want to do is enumerate the names of the files inside a directory you just need to do this:
string path = Application.StartupPath+@"file path";
.
.
.
string[] files = System.IO.Directory.GetFiles(path);
foreach ( string file in files )
{
... your code ...
}

Hi,
thanks a lot for your reply. No, Actually I was looking for a solution to use Windows Explorer to open a directory. I found the soltion as
System.Diagnostics.Process.Start("explorer.exe", "\"C:\\Temp\"");
Thanks again.
|
|
|
|
|
Try this:
System.Diagnostics.Process.Start("explorer.exe", "\"C:\\Temp\"");<br />
this code exploring folder C:\Temp
Best regards, Alexey.

Hello
In my code I am resizing the image. the following is my code:
public void resizeImage(int width, int height, Bitmap bmp){
System.Drawing.Size imgSize = new Size(width, height);
this.image_bmp = new Bitmap(bmp, imgSize);
}
the image gets distorted or I mean that the picyure quality is not
good.
what other things can we do to get good quality pictures

Create a Bitmap with the desired size, create a Graphics object for it and use that to draw the bitmap onto it. Set the SmoothingMode property of the graphics object to SmoothingMode.HighQuality to get the best drawing quality.
If you are enlarging the image, you can't expect a very good result. Even if the image is larger, it doesn't contain more image information than the original image.

Your software ought to work and your client should not have to install SQL Server Express. I hope your software works for your client

As long as you have externalized your connection string from your program, then you will not have any problems accessing any form of Sql Server.

Hi guys.Got a fractional function like the form y=(a0*s+a1*s+a2*s)/(b0*s+b1*s+b2*s).I put (a0,a1,a2)in txtNumer and(b0,b1,b2)in txtDenom like in the code below.What I have to write in txtFunction so I get as result in textbox the function.Or Im in a wrong path??Help please...
private void txtNumer_TextChanged(object sender, EventArgs e)
{
string numerator = String.Empty;
if (txtNumer.Text != String.Empty)
{
//put the text of textbox into a string
string source = txtNumer.Text;
//ndaje tekstin ne copat midis presjeve - per ekte na duhet nje array of strings
//se nuk e dime sa numra kemi shtypur ne tekst
string[] pieces = source.Split(',');
int[] numbers = new Int32[pieces.Length];
//we need an array of int or double to get numbers we put in textbox
//so we can convert them
for (int i = 0; i < pieces.Length; i++)
{
numbers[i] = System.Convert.ToInt32(pieces[i]);
}
}
}
private void txtDenom_TextChanged(object sender, EventArgs e)
{
string denominator = String.Empty;
if (txtDenom.Text != String.Empty)
{
//put the text of textbox into a string
string source = txtDenom.Text;
string[] pieces = source.Split(',');
int[] numbers = new Int32[pieces.Length];
///we need an array of int or double to get numbers we put in textbox
//so we can convert them and put them in output textbox
for (int i = 0; i < pieces.Length; i++)
{
numbers[i] = System.Convert.ToInt32(pieces[i]);
}
}
}
private void txtFunction_TextChanged(object sender, EventArgs e)
{
}

Any one used it from C#? Comments.
Also their login/create user accounts is disabled. Any other sources for the sdk? I am just looking at reading the files to make web reports from.
Thanks, Mike

Hi!
I have made an application that connects to a sql server by using the "add data source" method...all the connections have been made with datasets and everything is working.
What i would like to do is to be able to change the connection string, as it is now the connection string is set by c#
(Settings.settings = (Connection string),(Application scope),(Value=Data Source=VM2\SQLEXPRESS....)
however i would like to list all sql servers before login and when user clicks one of the sql servers listed, the connection should be made to this server and then continue with the login.
I have successfulla made a list of the names of the sql servers, but i know too little about how to change the connection settings.
In short, what i want to do is being able to within the program change the Value of the Data Source. I realize this may have to make me create a configuration file, but that is ok.
Can somebody please help me with a codesnippet to run before the connection is made or something?
Greatly appreciated

Here is one possible approach:
myapp.exe.config
<br />
<add key="ServerLocation", value=@"...path ..."><br />
here is my code snippet
[Serializable]
public class Servers:List<ServerData>
{}
[Serializable]
public class ServerData
{
string name;
string connection;
public string Name { get; set; }
public string Connection { get; set; }
}
public class myapp
{
...
string location = { depends on framework version as to how you
get your configuration setting }
...
FileStream stream = new FileStream( location, FileMode.Open );
XmlSerializer ser = new XmlSerializer ( typeof( Servers ) );
Servers serverList = ser.Deserialize( stream );
foreach ( ServerData connectionString in serverList )
{
myListBox.Items.Add ( connectionString.Name );
}
That should get you started.

Hi!
Im currently at work so i cant try that code, but looking at the code i cant really see where it changes the value of the connectionstring already made? this is really the only problem i have with my code so if you could point it out a little better for me it would be greatly appreciated as i'm a newbie 
Thank you for your answere!

Once you have your desired connection string you then create the connection. You do not want to have it hang around long since this is a rare resource. So you just use it, get what you need, and close the connection. You keep the connection global to your application. If a database is changed it is just a matter of creating a new Connection object.

Once again, thank you for your answere... I realize the problem of having the connection string hang around, but i think you may have misundestood me. The connection to the database is not made by the IP address of the SQL server, but rather the name of the server, for instance VM2\MSSQL... I do not want to have to recompile the program for every distribution since the name of the sql server may change, thats why i want to be able to change precisly that string that is created by c# so that it is changable within the program before making the connection, instead of having to recompile and distribute the program for each name the server may have.
Please correct me if i did not understand your post properly, thankfull for your help!

In my first post I indicate how you have a program config setting which points to the location of the collection of connection strings.
config ---> directory of XmlSerialized connection string object.
| |
v |
Program <-------------------------
The serialized object are as follows:
<Servers>
<Connection name="" connString="" />
<Connection name="" connString="" />
</Servers>
In the collection of connection strings (existing outside of the program) part of the string is server="". So you just need to change the server part of each connection string without the need to recompile the program. And if you need to move the directory that holds these definitions, just change the application config file to point to the new location.
