[Solved] A strange question about strings. [modified]

Hi all,

I need that application I'm developing can consider the same (=), 3 strings for example like these:

String A = "This, is, a, sample, 12345"
String B = "this, is,a, Sample ,12345"
String C = "This,is,a,sample,12345"

Someone know if there is a simple way (may be a single instruction?) to do that?
I know how to do that, but it is not a simple way.

Thanks

your question is unclear. IF what you want is a way to compare two strings ignoring white space, ignoring comma's and ignoring case, then the solution is two write a function MyStringCompare(ByVal string1 as String, ByVal string2 as String) as Integer wherein you first remove white space and comma's, and then use the built-in string compare function, telling it to ignore case.

If that is unclear to you, I strongly advice you to buy and study a book on the programming language of your choice.

Hi,

Yes, I need a way to compare 2 strings, ignoring spaces and case.
In the end of my question, I written that I know how to do that, but I was hoping that someone know a simpler way, or may be an already built-in instruction in V.B. to do this work.

Thanks for help and for "advice"

You can do a case insensitive comparison easy enough. I don't know there's a way to ignore spaces without actually removing them.

String.Compare takes a bool to say if it's case sensitive.

That for me has prioritary importance, is the problem of spaces.
The case insensitive comparation is a secondary requirement.
It seems that I can't avoid the work to delete spaces.......

No, because you're creating an odd definition of 'equal'. You may be able to use regex to create a string that allows arbitrary spaces between each character, but it seems like more work than just stripping them, to me.

Thanks for help,

I will evaluate what is more convenient to do.
Strings that I must compare can have until 23 commas!

hope so this will work , I did this thing for you but MVPs don't recommend this because copy paste will not enhance your programing skills

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


    Dim str1, str2 As String
    str1 = "softdev_sup"
    str2 = "Softdev_    sup"
    MessageBox.Show(String.Compare(str1, str2, False))
    MessageBox.Show(String.Compare(RemoveSpace(str1), RemoveSpace(str2), True))

End Sub

Public Function RemoveSpace(ByVal strText As String) As String
    Return System.Text.RegularExpressions.Regex.Replace(strText, " ", _
    String.Empty, System.Text.RegularExpressions.RegexOptions.IgnoreCase)
End Function

Hi,

The code you posted seems to be exactely that I was looking for.
With great surprise, differentely I was thinking, it is also fully compliant with Compact Framework, without any modification.
Running the code, the first message is "1" and second is "0".
To reduce the impact on the programing skills, I will do the work in 2 steps:
A first pass will exclude strings 100% equal (considering also spaces), from the 2nd pass that will compare only remaining strings using the RemoveSpace function.

Thank you very much.

storing bulk data is always the same, whether it is one image, one movie, one audio track.
CodeProject has lots of entries on storing images, and so does Google.

They (you) really want to store the MP3s in the DB? Personally I prefer to store them in the file system and then store meta-data about the files in the DB (ie: keywords, title, musician, etc...) along with the storage location in the file system.

Ask yourself when and how often does Form1_Load execute.

Can´t maintain login session in manually edited webbrowser

josemaloco6-Sep-09 1:35

I want to create "views" of a web page, to do that I´m retrieving and editing the html code to show what I want in a new small webbrowser:

Dim PageHTMLBytes() As Byte
Dim htmlText as string = ""

PageHTMLBytes = webClient.DownloadData(url)
' Convert result from byte array to string
Dim utf8 As New UTF8Encoding()
htmlText = utf8.GetString(PageHTMLBytes)
...
-Edit of the html code-
...
miniWebBrowser.DocumentText = editedhtmlText

The problem is that one part of the editedhtmlText I´m showing, is a flash object which checks if you are logged in, but it doesn´t matter if I logged before, as soon as I set my own, edited code, the session is lost. I tried setting cookies like this:

Dim request As HttpWebRequest = WebRequest.Create("http://www.cam4.com")

'Set cookies.
request.CookieContainer = New CookieContainer()
request.CookieContainer.Add(New Cookie("user", "usuario1", "/", url))
request.CookieContainer.Add(New Cookie("password", "password1", "/", url))

Dim response As HttpWebResponse = request.GetResponse()
Dim reader As IO.StreamReader = New IO.StreamReader(response.GetResponseStream(), True)
Dim html As String = reader.ReadToEnd()
web.DocumentText = html

..which throws no errors but no luck at all in keeping my session. I started to fiddle about with webrequest and responses instead of downloading the html code, but I couldn´t go much further.

I´m on Windows XP 32 bits, VB 2008 Express, Net. Framework 2.0 SP1 (for legacy support). Some assistance on how can I aboard this problem will be appreciated.

Press Enter key on command prompt in vb.net

Hi all

I am creating a program in which I am executing a bach file, which requires a "Enter key" hit to execute, as below :

Dim prc As New Process
            
With prc.StartInfo
.FileName = "e:\abc.bat" 'batchfile to execute
.UseShellExecute = False
.RedirectStandardInput = True
End With

prc.Start()
prc.StandardInput.WriteLine("{enter}")
prc.Close()

Now the above code run successfully and it appears a command prompt window showing "e:\abc.bat" file is executing but the code

prc.StandardInput.WriteLine("{enter}")

is not redirecting enter key to completely execute the batch file.

How can I use "Enter key" hit on that command prompt window in vb.net.

Thanks.

Thanks Henry for your suggestion but I have already tried these methods and there is no effect when a command window appears showing "abc.bat" is running.

I only want to do that when my batch file start executing, it takes a "Enter key hit" from program to completely execute my batch file(because it requires a Enter key hit for further execution)and not wait for hitting Enter mannually from user.

Suggest me how can I do that.

Thanks.

Hi,

I hava piece of code which creates a networl drive on the user's system. I need to hide the network.

The purpose of doing this is that the user while using an application need to connect to the Access db on a file server. But shouldn't know that the drive is mapped onhis computer.

Thanks
