If you're using .NET 2.0 or above, the DataGridView control is better than the (now deprecated, if not, it should be) DataGrid control.

<b>By using DirectoryEntry U can find Domain Name and then Use SchemanClassName for Getting Domain Related information </b>

Hello Monika,
You may try retrieving the ascii value for the record and then increment the ascii value and
then store back the back the value after charracter conversino.
Lets Say we have 'A' as value. Its ascii value is 65.
We increment this to 66 and convert it back to 66 which will save as 'B'.
You can try the given code. In this code snippet, I am adding the values in a button click which
add A-Z on each click.
<br />
If Me.ListBox1.Items.Count = 0 Then<br />
<br />
Me.ListBox1.Items.Add("A")<br />
<br />
Else<br />
<br />
Dim ch As String<br />
<br />
ch = Me.ListBox1.Items.Item(Me.ListBox1.Items.Count - 1)<br />
<br />
Dim num As Integer<br />
<br />
num = (Asc(ch) + 1) ' Gets the Ascii value of the last chrracter and increments it.<br />
<br />
Me.ListBox1.Items.Add(ChrW(num)) ' Converts the ascii value to charracter<br />
<br />
End If
Just try implementing it. I think this should give you a hint.
Hope this helps.

char x = 'A';
for (int i = 0; i < 100; i++)
{
x++;
x = x > 'Z' ? 'A' : x;
Console.WriteLine(x.ToString());
}

You're chating. The above is not VB code.

appreciate if some one could help me with using InfoMessage Event of ADODB.Connection object in VB6 and SQL server.
If I pass a single SQL Print command to the ADO object, it will fire the Event and works fine, but a print command among other commands doesn't work. Am I missing something??
here is the code
Thanks
Arash

Private WithEvents cn As ADODB.Connection
Private Sub cn_InfoMessage(ByVal pError As ADODB.Error, adStatus As ADODB.EventStatusEnum, ByVal pConnection As ADODB.Connection)
MsgBox pError.Description
End Sub
Private Sub Comm_UPD_Rec_Click()
SQLAdd = " DECLARE @Key int " & _
"SET @Key=(select (max(task_id)+1) from task) " & _
"insert into task (task_id,...)values (@Key ,...) " & _
" PRINT @Key"
Dim cmd As New ADODB.Command
cmd.CommandType = adCmdText
cmd.CommandText = SQLAdd
Set cmd.ActiveConnection = cn
out = cmd.Execute
End Sub

Perhaps the SQL statement block is invalid?? I don't see a space between (task_id,...) and values.
This would also be better handled if it was a stored procedure in the database and not in your code.

The rest of the SQL statement works fine, I mean all the commands in the command do what they are supposed to do, I was expecting the PRINT or RAISERROR fire the event but they don't. And the SQL command I posted is a part of a larger SQL command that the program generates according to the condition and it's far easier to create it on the client program rather than Server.
Thanks anyway.

I found the Answer
the SQL command shall be enclose in a Begin...End and SET NOCOUNT ON shall be used.
so the SQL would be like
SQLAdd = " Begin SET NOCOUNT ON; DECLARE @Key int " & _
"SET @Key=(select (max(task_id)+1) from task) " & _
"insert into task (task_id,...)values (@Key ,...) " & _
" PRINT @Key; End"
I also tryed placing Select @Key at the end of the SQL command, but without Begin...End and SET NOCOUNT ON
rs.open SQLAdd will not actually open the recordset and any attempts to read the rs will result in Error Object Closed. But if you place Select @Key after the End, rs will contain the @key.

The main menu on my application has the minimize button available and it works good. Clicking on a button on the main menu opens up a second form. This form also has a minimize button available but when you click it it minimizes the form just above the windows task bar. Instead, I would like it to minimize itself and also the main menu form to the task bar. How can this be done?
|
|
|
|

I assume the first form is mdicontainer for the second form.
In second form's (mdichild) form_ClientSizeChanged-event:
If Me.WindowState = FormWindowState.Minimized Then
Me.MdiParent.WindowState = FormWindowState.Minimized
End If

hi all,
i need to know,when i'm coding using vb to open an autocad file how can i determine the version of the autocad that my application will be open by
thnx
|
|
|
|
|
Launching the acad drawing file itself?? You can't. It'll be opened by the version that is registered to open that particular version of the file.
You'd have to use some kind of Autocad automation library to control which version opens the file in question. I don't if this exists or not. This would be a question for AutoDesk I would think...
The only other possibility would be to buld a command line string that launches the Autocad.exe you want with the drawing file as a command line parameter. Something like:
C:\Program Files\AutoDesk\Autocad 12\AutoCad.exe "C:\some folder\folder\other folder\someDrawingFile.dwg"
All of the folders and filenames in this example are hypothetical and may not relfect actual file/folder names in the real world.

Changes you make to the database will not show up in the application unless the DataSet is refreshed. That means rerunning the query that filled the dataset in the first place.
