Welcome to the VB.NET forum. I suggest you post your question in a more relevant forum, including a code-snippet of the code that throws the error.

Dear(s)
I somehow stuck. Pleaes help me in this regard.
I am trying to incorporte Arabic language support in my application. I have done the following.
1. Took Textbox with Arial Unicode MS Font and Arabic charset.
2. At backend I change my field to NVARCHAR to hold unicode.
Alls went well execpt, When i took input in arabic from user, the textbox gives me this ÚÇãÑ ÑÔíÏ after taking input. I ll try to convert it into string but fail.
And in SQL Server the Insert statement saves the same it get from textbox not the arabic text.
Please help me in this regard

The VB.NET IDE is available for free, as is the runtime. I strongly suggest you switch your platform. VB6 is no longer actively supported.
To make the decision easier; this is a problem with text-encodings. VB.NET would convert it to UTF and be done with it - no more "weird characters".

Dear Brother
Thanks very much for your reply, but I am working on an ERP having 7 fully functional modules, I cannot switch over right now the platform. Please help me.
Let me tell you this junk is displaying correct value in text box or crystal repots having font supports arabic charset. But at the time of saving in (Insert statement) textbox.text gives me this junk, How can I play with them.
Thanks in advance

There's nothing to play with. First, VB6 was know to have bad support for Right-to-Left text.
But, the textbox will display any text it's given, provided the font being used supports the appropriate characters. It'll look like junk if the font doesn't support it. So, where exactly are you seeing this "junk"?

Like I said, it's a dead language. If you want to use it, you'll be doing a lot of archeology.

Since when does VB6 have a "for-each"? Did I mention it's a dead language? Why are you still using it?

No one is going to just give you code. You must present what you have done so far and describe where you need assistance, then they might show you a way to solve your problem.
Good luck.

Does anyone have a code for VB program to set the time example 30 minutes could turn off the Internet (ADSL), much like internet cafes?
|
|
|
|
|
And you expect someone to just hand over their hard work for you to turn in as your own??
|

In that case, you'll be writing a proxy server. When a client connects to the proxy for the first time, you record the current time. Every time the client makes another request, you check the current time against the one that was recorded on first connection. Greater than 30 seconds? Don't forward the request to the destination server.

Cannot get instr function to work .net?
Using VB.net
For some reason, the 'instr' function and the 'string.indexof' is the same.
The problem is that one of the 2 string arguments, is a variable that is passed from the calling subroutine (not the literal characters) and it does not recognise the 'match'.
When I type in the literal characters with " " -- it works ok.
Here is a copy of the line that is not working.
'm' is the positional marker / 'largetxt' the body that is being searched and 'smalltxt' is the string that is being searched for.
intx = InStr(m, mainTxt, smallTxt)
The variable 'smallTxt' is the problem ---- if I have:
intx = InStr(m, mainTxt, "house") --- it works ok
Also ... same thing for:
intx = largeTxt.IndexOf(smallTxt, m)
Cheers

InStr is only there for converted VB6 code. It's been deprecated. Use string.IndexOf() instead.
Without seeing the contents of the variables, it's impossible to tell you why it isn't working with any confidence. These functions are case-sensitive, so that might be your problem, but...

Here is a sample for you...
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim maintext As String
Dim smalltext As String
Dim foundpos As Integer
Dim startpos As Integer
startpos = 0
maintext = "Jack and Jill"
smalltext = "and"
foundpos = maintext.IndexOf(smalltext, startpos)
If foundpos > 0 Then
MsgBox("match found at character " & foundpos)
Else
MsgBox("no match found")
End If
End Sub

Thank you both .
It the 'indexof' function also not working .... it gives a true result may one time in 20 (when I know it is a true hit).
I think there may be a bug in vb.net. It doesn't matter what I do, it comes up with -1 all the time.

|
|
|

Is there an alternative method ?.... .... I could spend 5 years tyring to get this one working - it's driving me crazy.
|
|

Yes theres INSTR,
If INSTR(Look-in-this-string", "For-This-String") > 0 Then
'REM A Match Was Found
Else
'REM No_Match_Was_Found
End If
and if you assign the result to a variable then the variable will give you the position...
LocationId = INSTR(Look-in-this-string", "For-This-String")
If LocationId > 0 Then
'REM A Match Was Found
Else
'REM No_Match_Was_Found
End If

.NET is a widely used framework, and looking for the position in a string is something most of us do. If there was a bug, it'd be found by now.
For these types of bugs, the answer is that "SELECT is not broken".

Did you try the code portion i added in my thread?
I tested it and it works fine...
obviously we can see the word AND is in the string JACK AND JILL.....
It makes me wonder what the ACTUAL strings are that you are comparing.
Maybe you could add them in a thread?
Its highly unlikely that the IndexOf method/function isnot working!
Its quite possible though that your installation of the development environment may have a corrupted file and possibly the next step would be to uninstall and re-install it again.
Still though, maybe you could save some time by adding your strings which your using in the comparision or even to upload the ACTUAL code block which is causing the offence?
Also, if your searching for a single character without specifying the number of consecutive characters to search, then the character must be in UNICODE, maybe that is of relavance?
Finally IndexOf is Zero based, so the FIRST character is position 0 then increases upwards, meaning it does not start with 1 but with zero.
Looking at the string "JACK AND JILL" and searching for a match of "AND" the code block I gave you states a match is found at charcter position 5, which taking it from a zero based index is ACTUALLY chracter 6 when starting from 1...
So maybe as a last resort you could subtract one from your start point (or start at zero anyway) and look for a match you KNOW exists in your string.
