My problem is when the file I am reading contains an accented character the streamreader simply ignores this character. So if the line I read in was a 10 bytes line, it now only writes back out a 9 byte line. This is a huge issue as the file I am working with has to be a fixed length. I know there is some encoding that can be done to make this work, but know very little about it. [Code]
View 3 RepliesBasically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted.
My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was.
I want to create a VB.NET function that will take a string containing accented characters and convert it into the non-accented equivalent. My particular requirement is associated with non-English names. Some real examples are timac, Huki, Bttcher, Bj¸rnbakk, rnrohr and Synneg. I would want to convert those examples to Stimac, Hukic, Bottcher, Bjornbakk, Furnrohr and Synnevag, respectively.I am aware that a(with an umlaut accent) is often replaced by 'ue' but replacing it with u is better for my purposes. Similarly, I want to replace with o, rather than 'oe'. I am assuming that all the required conversions will need to be hard-coded in the function.Are there any slick ways to write such a function, ideally preserving the capitalisation in the original string?

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?
Dim connString As String = "Data Source=" & pDataBase
conn = New SqlCeConnection(connString)
Dim strQuery As String = ""[code]......
I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.

View 2 RepliesOutlook is causing some problems when being passed a mailto string with accented characters in it. Changing the codepage for my entire webpage that has this string on it solves this problem, but that causes other problems in the system, so I would not like to do that.
A string like such returns a lot of garbage characters:
"mailto:Helpdesk-someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
Meanwhile, this cuts off the character after the "D"
"mailto:someemail@email.com?subject=Mon bâtiment / Départementé / Bureau n'est pas répertorié"
Attached is a file that creates a 3D cube, I did not make this but found it here at this site.Playing around with it I found out how to, on pressing of any key change the distance of the camera, thus changing the shade of the cube.So if you held a key down it got darker and darker.I want this to happen, but on a timer. So i created a timer, set the interval to 1 and did the same exact code. Set the timer to true, and nothing happens. Ever. I tried doing messagebox.show to show me a message every tick, and that didn't work either. So I went and broke the timer class?

Now i made a new application file, because I use timers all the time and it works. I copy pasted the code, and added the directx stuff, and it ..breaks my timer to do nothing at all ever.. Even if it is unrelated to my cube.

I was unhappy with the kerning in one of the installed fonts on my system, so I re-defined the kerning in a font editor and installed the revised font (under a new name) on my system. When I use the new font in Microsoft Word or Adobe Photoshop, my new kerning works fine - but when I use Drawstring in a VB program, although the new font is used, the kerning instructions are ignored.Does anyone know if this a feature of the Graphics.Drawstring method, or am I failing to set a switch somewhere? If it's a feature, is there another method which kerns correctly?

We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
[code]....
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string.
The application sits on a virtual environment and when I remote in and run the application, it connects to the remote database. However, when I remote in with a service account and double click the same .exe, it tries to connect to the local host database and ignores the app.config. The code is the same, only the login name I use is different. The login I use is part of the local admin group. Any ideas?

So I moved the code to an ASP.Net web app, which is impersonating a service account through the Impersonate section of web.config. The account I am impersonating does not have admin rights on any of the workstations so I put in a username/password into the constructor for the computer entry like so:
Dim deComputer As New DirectoryEntry("WinNT://" + Computername + ",computer", username, password).The username is that of a domain account which has local admin rights on every workstation. If I look at the Username property of the resulting deComputer object I can see that the username matches what I entered.Also if I enter in an invalid password it throws an error, so it is authenticating in some fashion.
However if I now try and add or remove a user from a remote workstation I get a general access denied error. If I add the service account that ASP.Net is using as a local admin on that workstation it will add and remove no problem.So next I tried using the LogonAPI (advapi32.dll ->LogonUser call) to login as the user account that is a local admin on all workstations, impersonated the resulting WindowsIdentitiy and tried running just the original deComputer instantiation. When I do this every property, excepty Path, returns an OLE exception..

View 3 RepliesI am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
