Re: string to int Tom Archer3-May-02 7:03 Tom Archer 3-May-02 7:03  You might even be able to do this through PInvoke, but I wouldn't necessarily recommend it I think I'll stick with "What is Convert?", Alex Cheers, Tom Archer Author, Inside C# A total abstainer is one who abstains from everything but abstention, and especially from inactivity in the affairs of others. Re: string to int Tom Archer3-May-02 6:14 Tom Archer 3-May-02 6:14  OOOPS!!!!! I've been in the MFC forum all day and my head is still in that Use the Convert static functions to do what you want. string s = "42"; int i = Convert.ToInt32(s); Cheers, Tom Archer Author, Inside C# A total abstainer is one who abstains from everything but abstention, and especially from inactivity in the affairs of others. Re: string to int ez23-May-02 6:25 ez2 3-May-02 6:25  What's the difference between convert and parse. string s = "42"; int i = int32.parse(s); Re: string to int Tom Archer3-May-02 6:39 Tom Archer 3-May-02 6:39  Parse is specific to the Int32 class while Convert is a generic class supporting all types.

Johnson3-May-02 6:52 James T. Johnson 3-May-02 6:52  It should also be noted that in the case of converting a string to an int via the Convert class it calls Int32.Parse. James Simplicity Rules! Re: string to int Tom Archer3-May-02 6:58 Tom Archer 3-May-02 6:58  Good point, James. I'm so accustomed to using the Convert class for everything that I never think about Parse.

Re: string to int tomiga3-May-02 7:04 tomiga 3-May-02 7:04  thx... i was looking for this conversion in string class. As I can see there is special class to conversions. Re: string to int ez23-May-02 7:34 ez2 3-May-02 7:34  So I guess my followup question would be when to use one or the other (parse vs. convert). Also, is parse more efficient? Just looking for some guidelines here. Re: string to int James T. Johnson3-May-02 13:16 James T. Johnson 3-May-02 13:16  Convert can convert from all intrinsic datatypes to the other types; parse only accepts strings. Convert also calls the appropriate parse method when converting a string to that format except when converting UInt32 which isn't CTS compliant and converting string to string where it just returns the value . I would use Convert for consistancy in code, but in some cases, Parse will take a few extra parameters you may wish to use. HTH, James Simplicity Rules! UI-less control (like an imagelist) 3-May-02 5:57 3-May-02 5:57  How do i create a control that when painted, does not show up on the form, but rather on the bottom like an imagelist does? Re: UI-less control (like an imagelist) James T. Johnson3-May-02 6:17 James T. Johnson 3-May-02 6:17  Have your class inherit from System.ComponentModel.Component instead of System.Windows.Forms.Control. HTH, James Simplicity Rules! ICodeCompiler: C# Compiler article Orion Buttigieg3-May-02 5:46 Orion Buttigieg 3-May-02 5:46  hello, this by the way is an excellent article. shows how to deal with the CodeDom object. i've been making some use of this object with some success. i can create the dll and write it to disk. the problem is that i'm trying to write the dll being generated to a directory of my choice. codeCompiler.CompileAssemblyFromSource(compilerParamaters, sourceWSProxy); this line automatically generates the dll in the bin\Debug of the application directory. i can't seem to over ride this. hope someone can help with this one. thanks Orion Orion Re: ICodeCompiler: C# Compiler article Tom Archer3-May-02 6:39 Tom Archer 3-May-02 6:39  Um, what article?

Re: ICodeCompiler: C# Compiler article James T. Johnson3-May-02 6:57 James T. Johnson 3-May-02 6:57  This one James Simplicity Rules! Re: ICodeCompiler: C# Compiler article Orion Buttigieg3-May-02 6:59 Orion Buttigieg 3-May-02 6:59  hello Tom, if you search this site for ICodeCompiler or CodeDom you should get a couple of articles. one by Konrad Rotuski "C# Compiler" and the other by Shawn Wildermuth "Runtime C# Expression Evaluator ". both are basically the same. here's the link to the first one. http://www.codeproject.com/csharp/cscompiler.asp thanks Orion Re: ICodeCompiler: C# Compiler article Tom Archer3-May-02 7:05 Tom Archer 3-May-02 7:05  Yeah. I know where the article is. The subtle point was to let you know that you need to include links like this instead of assuming the people helping out here have the time to go searching for them Cheers, Tom Archer Author, Inside C# A total abstainer is one who abstains from everything but abstention, and especially from inactivity in the affairs of others. Re: ICodeCompiler: C# Compiler article Orion Buttigieg3-May-02 7:11 Orion Buttigieg 3-May-02 7:11  your right. my apologies did you need any other info? the ICodeCompiler doesn't have any properties i can set. and the dll will be written before its assigned to the CompilerResults object. ideally i'd like to write it to the MS temp directory.

If nobody has figured this out by the time I get home (I'm on the way to pick up kids now), I'll look at it tonight and try and help.

If you are writing a C# program, everything is managed. You can't access an unmanaged resource. Unless you meant something else.

Johnson2-May-02 22:44 James T. Johnson 2-May-02 22:44  An unmanaged resource is a file, database connection, HPEN, HDC, HBITMAP, etc... There are wrappers around all of those resources each providing you with a Dispose method which will free the handle; in the case of Files and Database Connections you have appropriate Close methods you can call as well. James Simplicity Rules! Re: Normal Resources ? Nish Nishant2-May-02 22:50 Nish Nishant 2-May-02 22:50  Thanks James. But my idea was that Dispose is automatically called. I wasn't aware that we need to call it manually. Unless we are talking of our own wrapper class.
