([^,]*,[^,]*,[^;,]*);?

This matches the last group. The ? means the ; is optional, without it, you won't match the last group.

([^,]*,[^,]*,[^;,]*);?

Is this the final expression I should use? Because, you posted a couple and I'm confused. This particular expression when ran against this string ...

Day,Amount,Direction;3,100,West;5,43,North;5,44,North West;7,54,South;2,5995,East;,,;,,;,,;54,35345,;,543,North;6,,West

... returns all the groupes of three correctly.

Day,Amount,Direction;
3,100,West;
5,43,North;
5,44,North West;
7,54,South;
2,5995,East;
,,;
,,;
,,;
54,35345,;
,543,North;
6,,West

However, I would like to be able to replace a part of the expression with a number or a word, eg.

(5,[^,]*,[^;,]*);?
(Day,[^,]*,[^;,]*);?
([^,]*,44,[^;,]*);?
([^,]*,[^,]*,North West);?
([^,]*,[^,]*,North);?
Day, Ammount, Direction
etc...

It might help to visualize the above string as an HTML table (because that's what it is)

Can you tell me how to use your expression to do queries like above?

Don't worry about the last message i can just add a semi colon to the end and it works. But can you make it so it won't include the semicolon in the match?

To reiterate:

([^,]*,[^,]*,[^;]*);?

This matches all including the ;. $1 is the group within the match that doesn't include the ;.

Hi,

I would like to use this expression, but I'm am confused about how to modify it for use with this input string:

Day;Amount;Direction

How would the regex change? would it be:

([^;]*;[^;]*;[^;]*)

IS it possible to integrate c# with PHP?

Re: c#-PHP integration

One way, but not the other. As php is not a compiled language, c# can not directly call php code. A php page might be able to use a dll written in c#.

C#.net pages and php pages can work in the same web. Interaction between the pages has to be done using querystrings, cookies, files or database, though.

Depends on what you mean by "integrate". There is no limit to the number of "modules" your web server can process. A web server can host ASP.Net with C# code behind as well as have PHP.

So what do you mean by "integrate"? Web applications written in ASP.Net can live besides PHP web applications. As long as you keep the abstraction at the Http level, web applications can "talk" to each other just fine. If you were thinking they could share data structures below web queries/posting though that is not possible.

trying to embed a legacy COM dll in c# form. ABle to create the object but not able to dereference one of it's fields. It should be a float array -->
GSpcIOLib.GSpcIO myspc = new GSpcIOLib.GSpcIO();
myspc.OpenFile("c:\\work\\honeydew.spc");
object xfloat = myspc.XPoints;
if I view xfloat in the debugger I can see the array of floats but if I try and do something like this float myfloat = xfloat[1]; I get an error -->
Error 1 Cannot apply indexing with [] to an expression of type object

You can't do much with an object without specifying what it really is. If you have an array of floats, you can either access it by casting the object to a float array:

myfloat = ((float[])xfloat)[0];

or by declaring xfloat as a float array:

float[] xfloat = myspc.XPoints;

You can do it using the windows API. I don't remember exactly, but you use FindWindow I think, with some paramter like SET_TEXT or something. There's an example that does exactly what you want somewhere on pinvoke.net[^]

Control Key Capture in Win Forms

malharone1-Aug-05 10:41

malharone

1-Aug-05 10:41

I have a .Net Win form which has a) main menu, b) tree control, c) a custom control to display details of the selected TreeNode
-----------------------------
MainMenu:
mnuDelete -> [del]
mnuCopy -> [ctrl+c]
mnuCut -> [ctrl+x]
mnuPaste -> [ctrl+v]

Tree Control: is the standard .Net treeview with HideSelection = false. (So the selected node is always highlighted even if the input focus is moved to another control)

Detail view Custom Control: Contains few textboxes

The problem I'm having is that when I'm on detail view, and making changes in the textbox, I press CTRL + [C, X, V] or Delete keys on the keyboard, but the key is captured by the main menu, and which trigger an event for {menu_name}_click(...). I do not want this event to be fired but want it to be handled by the textbox control.

Any suggestions would be greatly appreciated.

Thanks.

I believe the textbox has a property for if it swallows key events or passes them on.

I have a c# windows service that I have installed on a number of servers, but when I try to install it on this one particular server I get the following error when running installutil:

No public installers with the RunInstallerAttribute.Yes attribute could be found in the xxx assembly.
Remove InstallState file because there are no installers.

Has anyone run into this before?

is this problem related to thread issue
as you know you now have synchronize access to the file
you need to take care when you read while you are write
at the same time
so you have to consider some thread synchronization
in your code
Note:not all thread synchronization available in .net
will work for interprocess communication

Put writing/reading stuff into lock block, it should work for you.

i think using lock may not work in his case
because when using lock you actutually using Monitor
which Prevents more than one thread at a time from accessing a file but it have not ability to span application and process boundaries

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
