Removing CR-LF's from a string using Regex sultan_of_6string15-Jul-02 6:07 sultan_of_6string 15-Jul-02 6:07  Hi! I've got these strings that have \r\n's in them. I wanted to know if there is a way to remove them from the string using the .NET regular expression engine, instead of StringBuilder. Thanks and sorry about the double-post. Re: Removing CR-LF's from a string using Regex leppie15-Jul-02 6:49 leppie 15-Jul-02 6:49  Hi, wouldn't a string.Replace("\r\n", "") work?

Re: Removing CR-LF's from a string using Regex leppie15-Jul-02 7:57 leppie 15-Jul-02 7:57  Thats why I have not ventured in Regex Land But I have to now, strings are just getting too complicated.

Tab control Martin Haesemeyer15-Jul-02 2:53 Martin Haesemeyer 15-Jul-02 2:53  Hi everybody! Am I just stupid or isn't there any clean way to disable a whole tab page (with the effect, that the "tab" of the page is greyed and it can't be selected)? Or is it not advised to do so? Cheers TIA Martin [Edit] Ok, Ok it inherits from control and therefore has an "Enabled" property although this is neither listed in the docs nor present in the designer or intelli sense.... Oh wait! Of course it's not listed because it doesn't do anything useful!

Re: file renaming sultan_of_6string15-Jul-02 6:01 sultan_of_6string 15-Jul-02 6:01  Use System.IO.File.Move(originalName, newName); After all, renaming is just moving it to the same folder with a different name. Re: file renaming leppie15-Jul-02 6:04 leppie 15-Jul-02 6:04  Hi Very easy indeed From the static methods in the File class. e.g. File.Move(oldfilename, newfilename); Moving has exactly the same effect as renaming except that you can rename to any path. But just to rename keep the paths the same. Now go finish that class! READ MSDN static variable gekoscan14-Jul-02 12:19 gekoscan 14-Jul-02 12:19  In Visual C++ I could declare a static inside a function and no matter how many times this function was called it would only be called once. ie. public void foo1() { static int iCount = 0; iCount++; Console.WriteLine(iCount); } public void foo2() { while(true) foo1(); } This example should just continue to increment a value in the console because the initialization is only done once. How is this done in C#?

How is this done in C#? It wouldn't be allowed. Static data would have to live in the class and not the methods. Also, Static anything has to have a full referrence to it. As an example: class myOwn { static int myStaticStore = 0; public int myMember(int StaticStore) { myOwn.myStaticStore=StaticStore; return myOwn.myStaticStore; } } Rocky Moore Thanks but no gekoscan14-Jul-02 13:24 gekoscan 14-Jul-02 13:24  Nope see in C++ this is totally allowed and it makes recurrsion really nice and easy. If I want to write a recursive function I want to be able to have variables inside the method that all the instances of that method can see. I don't want to have 4 variables declared globally inside a class when only 1 method is using them. I want to declare them static inside a method so only 1 instance exists for all instances of that method. If this isn't somehow possible in C# then this language has been totally *ucked for recurrsion (GOOD JOB Microsoft). You just took some real horsepower out of your own language.

You just took some real horsepower out of your own language It has the same functionality, only the scope of the variable is global to the class rather than per member. You will still only have _one_ varible, for all instances of the class just like in C++. The only time you would have a concern is if you planned to use a static variable of the same name in multiple methods as you could do in C++. Since they are up at the class level they would have to have different names. Rocky Moore Re: Thanks but no Jonathan Tan15-Jul-02 0:05 Jonathan Tan 15-Jul-02 0:05  Well...VB6 also has a "static" modifier that works the same way as C++...i don't know if VB.NET still has it...but it should be quite simple to implement in C# and yet Microsoft doesn't do it...another one is the With block which is in VB but not in C#...how irritating Re: Thanks but no Rocky Moore15-Jul-02 10:24 Rocky Moore 15-Jul-02 10:24  Jonathan Tan wrote: another one is the With block which is in VB but not in C#...how irritating I agree with that. Would have been nice. I am just glad they put in "Using" to shorten all those referrence calls!

Thanx in advance READ MSDN Re: Data Link Dialog Box???

Not quite sure what you are asking. If you just want to modify the connection in a Wizard form, you can righ click on the connection you used in the Server Explorer and select Modify Connection.

Feng Qin14-Jul-02 19:55 Feng Qin 14-Jul-02 19:55  Code: MSDASC.DataLinks dl = new MSDASC.DataLinks(); dl.PromptNew(); You can find the whole information on msdn : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnsqlmag2k/html/LinkAPI.asp In C# project, you should add a com reference named : Microsoft OLE DB Service Component 1.0 Type Library Good luck! I'm amumu, and you? Re: Data Link Dialog Box??? leppie14-Jul-02 23:13 leppie 14-Jul-02 23:13  Thx , exactly what I need, but how does one "cast" the returned object to an OleDbConnection? or a ConnectionString? I presume I will need to implement a UITypeEditor as well as I need to show the property through a property grid. READ MSDN Re: Data Link Dialog Box??? Feng Qin15-Jul-02 16:39 Feng Qin 15-Jul-02 16:39  MSDASC.DataLinks dl = new MSDASC.DataLinks(); ADODB.Connection connection = dl.PromptNew() as ADODB.Connection; if( null != connection ) MessageBox.Show( connection.ConnectionString ); You should add reference "Microsoft OLE DB Service Component 1.0 Type Library" and the "Microsoft ActiveX Data Objects 2.5 Library" to your project's reference. I'm amumu, and you?

Cant test now but it should work. It just seems a bit over the top for such a "small" thing. Another question, if you want to run this on another machine, do u need to register both dll's on the other PC or is the Interop.*.dll files ok for that? READ MSDN Re: Data Link Dialog Box??? Feng Qin16-Jul-02 0:59 Feng Qin 16-Jul-02 0:59  I think all dlls you refered are running at local machine, and two support remoting: web service and system.remoting, right? I'm not sure about it. And also you can notice if you add a reference, vs.net will copy the file to your bin directory, does it means dll will be invoked local? I'm amumu, and you?
