Resolved Normalize Path With Length More Than 260 Chars?
Feb 8, 2010
My issue is to combine two paths which one or both of them may contain double dots. I used Path.Combine(string, string) and the returned string is still a long path as a result of concatenating these two paths. Single or double dots are not eliminated.
So, I tried to use Path.GetFullPath(string) method with the concatenated path as the argument.PathTooLongException is thrown because this path has more than 260 characters. However, if this path is normalized, it won't exceed the maximum characters for a file path.

I'm creating a radio streaming application, which plays a live stream from various radio stations in a small 'gadget' like application.
The user can add his own custom radio stations, by supplying a Name, a StreamUrl and, optionally, an Image that represents a logo or something of that radio station.The logo will be drawn on the main form when that station is selected.
I need to be able to save these custom stations, and I think it makes sense to use an XML file, which could then look something like this
<CustomStations>
<Station>
<Name>Radio 1</Name>
[code]....
Before I added the support for images, this worked fine, how to store the images. I want the user to be able to select any image from his harddrive, but I don't want to force him to keep that image in the same location afterwards. So I can't rely on the path that he selected. Instead, I want to simply load the image from the path he selected, and then save it somewhere else.
I am storing the XML file in the common application data path which I think is a good place for the images too.The problem is, how to determine a name for the images? I will always have just one image per custom radio station, so it makes sense to me to simply have one Images folder that holds all images, with a unique name.I can see two solutions:
1. Generate a random filename for every image
2. Use the Name of the radio station as the image name
For option 1, I suppose I could just create a string of 16 random characters and call that the filename. The problem of course is that there is no guarantee that I will get a unique filename. Yes, the chances of generating the same name twice randomly are very tiny, but it's still possible, and I just don't like that. How can I ensure that my random filename is unique? I suppose I could always drop the whole thing in a While loop that continues when the new filename already exists, but there must be a better way... Is there nothing in the framework that allows me to generate a unique random filename, in a directory of my choice (so not in the Temp directory...)
I like option 2 much better. The Name of a radio station is unique (there can't be two stations with the same name), so I don't have to worry about filenames conflicting. The problem with this approach is that there are no restrictions on the name. There's nothing stopping the user from naming their custom station "Radio~/aij!""_.fe" or something like that, which is obviously not a valid filename... So, I will have to do 'something' to generate a valid filename from the station name. I could simply remove all non-valid path characters from the name, but then I am no longer guaranteed a unique filename... Suppose there's two stations, one called "Radio/1" and one "Radio1", then after removing the invalid "/" character, the names will be the same and so I will generate the same image path for both....

I have some problems that about GraphicsPath:
How to measure a path's length?
How to insert a point along the path without changing its pattern?
and how to get a nearest point along the path with a given point?
or
get a on-path-point with a given percentage of the length of the path,
e.g.: 3/4 of Path(new point(){(0,0),(2,4)}) = (1.5,3)
(like Adobe Flash, the object can follow a path to move.)
I have tried to measure length with Graphicspath.flatten, but it takes time and not accurate enough. Is there a formula to do that?

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

I am new to the Window's API and have been trying to just poke around with it. It was suggested to me to try making a time tracker program that will track how long a window is actively being used and keep windows from the same .exe file grouped together. Things have been going good so far, but I am having trouble with the GetModuleFileNameEx command.
According to MSDN if GetModuleFileNameEx succeeds it should return the length of the path name; however, when I output the return value of GetModuleFileNameEx, it is just a random long number that changes with every tick of the timer. Also when i try to output the path of the open window just to see what is being stored there, it is blank. I have googled and surfed the net for but to no avail. I was curious if someone here might have an answer for me Here is the code I am having trouble with:

In my system each member will have an address and so do no other entity.I choosed to put address in a seperate entity but there exists two inconsistencies.
1- While the one and onlt entity which address is being used in is member, why should I consider it as an independent entity?
2- My adress fields are address 1, address 2, ...., address 6 which I think the naming convention is not good enough.

I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

I wrote a small application for a friend that opens a Excel sheet, get's some data from it and stores that data into a file. I compiled it for AnyCPU (I also did a compile just for his 64 bit machine, same result).Here is the problem:He is able to run the program on a 32 bit computer without any problem, it just won't work on his 64 bit computer.Here is the error he is getting App failed to initialize properly (0xc0000135)
Is this my problem or could this be his problem? As far as I can tell I'm all up to date with VS2008.Is there somewhere I can look specifically what the latest build is for VS2008? I am using VB2008.

I'm working through the Pro ASP.NET MVC Framework book by Apress (which is great, btw) and it's in C# although we mostly work in VB so I'm "translating" the examples along the way. So far so good but I ran into something that has thrown me.Long story short we need to validate that the string the user gave us as an email address. This returns true in C#:
Console.WriteLine(System.Text.RegularExpressions.R egex.IsMatch("Me@me.com", ".+\@.+\..+"));
But this returns false in VB:Console.WriteLine(System.Text.RegularExpressions.R egex.IsMatch("Me@me.com", ".+\@.+\..+"))

This one is causing me a lot of frustration, and as far as I can see, it should work. What I have is a form with 9 ListViews (ListView1 through 9), and I want to add items to them.The issue is, I have a routine that sets which ListView to use. Say I have set it for ListView4, it works initially on the first file, but after one line of code. it reverts back to ListView1 for the remaining files.

Yesterday s**ked, and today ain't (sic) looking better. I have an application I have been working on and it can be slow to start when my ISP is down because of DNS. My ISP was down for 3 hours yesterday, so I didn't think much about this piece of code I had added, until I found that it is always slow to start. This code is supposed to return your IP address and my reading of the link suggests that should be immediate, but it isn't, at least on my machine.Oh, and yesterday before the internet went down, I upgraded (oymoron) to XP SP3, and have had other problems.So my questions / request:
1. Am I doing this right?
2. If you run this on your machine does it take 39 seconds to return your IP address? [code]

I'm just having some difficulty with nitpicky details. To give you a gauge of the level of programming I'm at I'll just tell you about some of the work I've done. Of course, you can skip down to the last paragraph if you don't have the time.I've created an emulator for a programming language I call "Blue Code". It's kinda a spoof on Redcode, which you may have read about before. You load programs which use simple commands like add, divide, copy, jump, split (like making a new thread), etc. You can load multiple programs in and each instruction sits on a line of a circular memory. Then each program takes turns trying to get the other to run an illegal function, at which time it looses. I think it's quite a bit better than Redcode actually.I also wrote a program a couple years back (when I was 13?) that draws fractal trees, it's quite fun.
So, I have a pretty good grasp on VB, but recently I got into 3D graphics using the Direct3D library. Unfortunately, the function I'm using to save meshes is not working. I know the rest of my program works just dandy because I've loaded quite a few sample meshes. Now, I've come to the conclusion that my saving code is irreparably broken, so I won't even show it to you. What I need is somebody to write an outline of what I need in a saving function, or, better yet, actually write a saving function which I can customize to my purposes. The parameters are, a somewhat unconventional List(of List(of CustomVertex.PositionNormalTextured)), List(of Material), and List(of String). List of lists includes a bunch of lists of vertices I wish to use, where each list represents a subroutine. The list of strings and list of materials represent texture file names and surface materials respectively.
