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.

VS 2010 Generate Image Path From Unique Name, What To Do With Invalid Chars

Apr 15, 2010

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....

Measure A Path's Length?

Dec 2, 2009

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?

.net - Regex Replacing Non-words Chars In Strings, Ignoring Specific Chars?

Oct 8, 2011

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]"

MSDN If GetModuleFileNameEx Succeeds It Should Return The Length Of The Path Name

Jun 25, 2009

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:

[RESOLVED] Simple 3D Graphics With DirectX

Jun 6, 2010

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.
