Nope. The OEM app has to be rewritten to "access" your app and use the extra functions.

what about this concept.

making one of your vb program executable then when trying to access the vbprogram from another vbprogram. use

'with an onclik event
shell "vbprogram1.exe";

Re: Passing parameter to hardcoded SQL statement (non Stored Procedure)

Well, the main way would be stored procs, if you can't do that, then you can use parameterised querys. Last resort is to do some string mashing to pass in your parameter, but that opens you to SQL injection attacks.

Dim strSearch As String
txtSearch.Text = strSearch

This sets your search string to an empty string, of course. It also means your db code is in your presentation layer, which means your app is poorly designed ( well, not designed at all, really ).

I suspect your main problem is that you're not putting '' around your search string.

This happened because the original poster deleted his question, thereby orphaning the replys he got. It's a known issue and won't be fixed until the next release of the CodeProject web site.

Help! Read Unicode Text File to VB program

13-Jul-07 2:58

Hi,

I am using Visual Studio 2005's Visual Basic developer. I have a problem that i need to extract the unicode from a text file to my progam. And normal character have not a problem but when come to a certain extent of the unicode set, it prompt a error saying that it is invaild.

Here is my code:

OpenFileDialog1.ShowDialog()
Dim direct As String
direct = OpenFileDialog1.FileName
Dim fs As FileStream
fs = New FileStream(direct, FileMode.Open)
Dim sr As StreamReader
sr = New StreamReader(fs)
Dim n1 As Integer
Dim s1(100) As Char
Dim n2 As Integer
n2 = 0
While sr.Peek >= -1
n1 = sr.Read()
s1(n2) = Chr(n1)
n2 += 1
End While

my input is this unicode, §. So when it read from file to here, it prompt the error. So please help me...!

Thanks and Regards,
A person who don't whether he is a newbie or novice. Smile | :)

Wow - what a mess.

1 - why do you limit yourself to 100 characters, instead of using a List or something ?
2 - why do you read one character at a time ?

File.ReadAllText will read an entire file in one line of code.

Hi,

thanks for commenting my previous program. I know that it is really in a WOW mess.

I try you method but I still have the unicode conversion problem that I posted in the first thread.

I appreciate your help. I have shorten the whole program as follows:

OpenFileDialog1.ShowDialog()
Dim direct As String
direct = OpenFileDialog1.FileName
Dim str As String
Dim adder As Integer
Dim reader As Integer
reader = 0
adder = 0
str = File.ReadAllText(direct)
reader = str.Length
Do While (adder <> reader)
Try
ComboBox1.Items.Add(str.Chars(adder))
adder += 1
Catch ex As Exception

End Try
Loop

So please help mi from the unicode's ASCII index is 167 after conversion. It is simple when you type in the unicode in to the windows form but I try to retrieve from file. WoW, it is very different and difficult, so need you people out that who is experted in it to help me out...

Thanks and Regards,

Dave Kreskowiak13-Jul-07 4:54

What does the code look like that wrote the file?? Maybe it's not really Unicode where you think it is.

Or, there's another possilibity. Change the ReadAllText line to:

Imports System.Io
Imports System.Text

.
.
.
 
    str = File.ReadAllText(direct, Encoding.Unicode)

Array -> listview1.groups.addrange

how do i make a array and fill the listview1.groups.addrange(arrayname) with the array?

i want to add groups this way so i can sort the array and add the groups name in the right order: A-Z

i dont have a lot experience with arrays.

thanks for your help!

Dave Kreskowiak13-Jul-07 4:19

13-Jul-07 4:19

If you don't know anything about arrays, I highly suggest picking up a book on VB.NET and going through it. Without this basic knowledge, you're going to find most projects impossible to do.

Dim groupNames(2) As String
groupNames(0) = "Group2"
groupNames(1) = "Group3"
groupNames(2) = "Group1"

Array.Sort(groupNames)
For Each groupName As String In groupNames
    ListView1.Groups.Add(New ListViewGroup(groupName))
Next

I've kept this example very simple. There's another method for creating a ListViewGroup array, that can be used with AddRange, that uses an Array's ConvertAll method, but you have to supply a Converter delegate and method to do the conversion from String to a ListViewGroup object. But, if you don't know arrays, this litte topic will not make any sense at all...

Define "does not work". What DOES happen?? Do you get an error message??

Is your code running on Windows XP or above? Did you EnableVisualStyles in your project?

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
        Dim groupNames(2) As String<br />
        groupNames(0) = "Group2"<br />
        groupNames(1) = "Group3"<br />
        groupNames(2) = "Group1"<br />
<br />
        Array.Sort(groupNames)<br />
        '        ListView1.Groups.Add("Group1", "Group1")<br />
        For Each groupName As String In groupNames<br />
            ListView1.Groups.Add(New ListViewGroup(groupName))<br />
        Next<br />
        ListView1.Items.Add("Item1", 0).Group = ListView1.Groups("Group1")<br />
        ListView1.Items.Add("Item2", 0).Group = ListView1.Groups("Group2")<br />
        ListView1.Items.Add("Item3", 0).Group = ListView1.Groups("Group3")<br />
    End Sub

i get a group "Default" with item1, item2, item3 in it.

thx

how to know a structure of a project

Change the group creation code to add a Name to each group:

For Each groupName As String In groupNames
    Dim lvg As New ListViewGroup(groupName)
    lvg.Name = groupName
    ListView1.Groups.Add(lvg)
Next

You're treading in the waters of the ASP.NET forum. Your question really has nothing to do with VB.NET.

But, yes, a cookie that expires in a short time would do this. Ask this question in the ASP.NET Forum for more info.
