VS 2008 [RESOLVED] System.Net.Dns.GetHostAddresses
Apr 9, 2010
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]

One last note. If I resolve a name all is well.

In uTorrent the system shuts down whether the user is logged in or the system is locked, how is that possible?Also I would like to know how to detect if the system is locked or not because if they are logged in I, like uTorrent, would like to prompt the user that the system is about to shut down and give them 30 seconds to cancel it.
In addition to
Process.Start("shutdown.exe", "-s -t 05")
I also know about

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. (itmModelItem = lvwModels.Items.Add(ModelName) in AddModel.

I have another problem:
Sub download()
Try
GetPass()
GetUser()
GetPath()
[CODE]...
Bolded line makes an exception: The remote name could not be resolved: 'unkn' I guess it has to do something with threading, and path doesnt generate correctly username, password, and pth are generated from objects in another form, so i did it like this: Dim newfrm As Form1
And then acces the objects that hold user, pass... like: newfrm.textbox1.text
So, why do i get this exception then if im doing it the right way, and how do i get this to work?

Hi
I have a thread that it calling many processes.
While the processes are executed (spends some seconds or minutes in completing all the tasks) I show form "Please wait to complete all tasks".
But one of these processes I have to show a form because the user has to choose a few data. But the problem is that this form is showed minimized.
Already I have tried to show it maximized and to bring it to the front but it does not do it.
how I can show this form to front and maximized?
My actual code is:
f= New frmLPlantillas
f.WindowState = FormWindowState.Maximized
f.BringToFront()
If f.ShowDialog() = DialogResult.OK Then
value1= f.xxxx
value2= f.zzzzz
value3= f.aaaa
value4= f.bbbbbb
Else
Return False
Exit Function
End If
Thanks in advance.

This showed up this morning in my error list.
Quote:Error1The item "objDebugArtScheduler_2.ImagePreview.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.ArtScheduler_2 What I did this morning was add a filter line to my openfiledialog in the ImagePreview form and deleted the settings in the designer Looked in project properties under debug and resources and don't find anything.Looked in the objDebug folder on drive and it listed two of the same files, same size and timestamp. Deleted one. Still get same error.Program runs (F5) after clicking yes, accepting that there is an error and to still run.Have not tried to publish. Don't know if this would corrupt the working version already published or not.

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.

[code]...
I want to know how to make a keygen that will generate a letter/number randomly out some example letters which would need to be defined.E.G.Random number out of 0-9 (0,1,2,3 etc) Random letter from A-Z (A,B,C etc) And then obviously display generated key in TextBox. Ideally i would like to improve this more but if i could get the basics then i would move on from there

I am wanting to use a vnc installer as an embedded resource, and if the computer running the program does not have vnc installed then typing in a password will install vnc. I have tried everything I can think of and running the process from my computer works, however when ran on a different computer i get the error "File not Found". I am sure I am not calling the embedded resource correctly. I am using Process.Start(" ightvnc.exe /S")

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", ".+\@.+\..+"))

GUI: textbox1.Text, button, textbox2.Text What i want to do is when the user inputs an 8 bit binary number The program finds the places of ones and outputs them For example: user inputs 00010011, the program outputs a 4,1,0 because the 7th place is the one closest to the left and the 0th place is the farthest, e.g. 76543210 is and in the 8bit string the 4th 1st and 0th are ones I was thinking of something like this:

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.

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.

Basically, I have a ListBox with a list of items that correspond to pictures.I have it set up so that when you selected the first word on the list (index 0), then the image 0.png is displayed (index 1 = 1.png, etc) in the Picture Box and the Picture Box resizes to fit the Image.
[code]...
This^ works fine, but I want to center the picture in the group box that it is in each time a different image in selected.My solution was this:
[code]...
No compilation errors, but it^ doesn't center the image. As a matter of fact, there's no noticeable difference at all.

I have been searching for quite some time, and while this might be easier than I am making it, but this is the first time I have tried to do something like this. My issue is that I am creating a pdf and need to include am image that I have to download from a dynamic URL. The issue I am having is how do I get the image saved to a file on our server? As far as I have seen, there is not a way to directly put in the image into the pdf - but if you know a way to do this, that might work instead.
