Curious. How are you adding the COM Guids to your assembly?? When I need to create a COM component in VB.NET, this[^] is the template I follow.
|
|
|
|
|
I used this[^]. The class worked great and I am still confused why they say I must use
Regasm AssemblyName.dll /tlb: FileName.tlb /codebase
and not
Regasm AssemblyName.dll /codebase<br />
Regasm AssemblyName.dll /tlb: FileName.tlb /codebase .
I may be totally wrong but the only thing that worked for me was that 2nd way which I found here, partially[^] but I ended up having to use the combination of the 2.
I was successful installing to the GAC but the combination of installing to the GAC and registering the assembly seemed to confuse the code.

I'v created a crystal report with the 'mail label' expert and everything is working fine. But now I want to adjust the size of the label, but I can't seem to find where I can do this without remaking the report with the wizard.
Anyone know where this is located?
If my help was helpfull let me know, if not let me know why.

There's a walkthrough in the MSDN documentation that comes with Visual Studio. Open Visual Studio and hit F1. In the Documnet Explorer that comes up, click on the Index tab, then type "Web service, creating" into the "Look for" box.

What does one of these text file look like? What you do depends on the format of the text file. You cannot just load text into a datagridview. It has to be parsed into columns, probably put into a DataTable object, then you bind the grid to that datatable. Saving changes becomes a problem if the text file is not in the correct format.

Hello Chris,
I believe this code snippet should help you atleast to browse and load text files into the
datagrid.
Dim strFileName As String
Dim strFilePath As String
Dim sSlash As Single
Dim FileDialog As New OpenFileDialog
Try
With FileDialog
.Title = "Import Sage CSV file"
.InitialDirectory = "D:\Accounts"
.Filter = "Text Files | *.txt|All files|*.*"
.ShowDialog()
sSlash = InStrRev(.FileName, "\")
strFilePath = Mid(.FileName, 1, sSlash)
strFileName = Mid(.FileName, sSlash + 1, Len(.FileName))
End With
Dim strConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & strFilePath & ";" _
& "Extended Properties=""text;HDR=NO;FMT=Delimited"""
Dim conn As New OleDb.OleDbConnection(strConnectionString)
conn.Open() ' Open connection with the database.
Dim objCmdSelect As New OleDb.OleDbCommand("SELECT * FROM [" & strFileName & "]", conn) ' Create new OleDbCommand to return data from worksheet.
'Dim objCmdSelect As New OleDb.OleDbCommand("Select * from [Sheet1$]", conn) ' Create new OleDbCommand to return data from worksheet.
' Create new OleDbDataAdapter that is used to build a DataSet based on the preceding SQL SELECT statement.
Dim objAdapter1 As New OleDb.OleDbDataAdapter
objAdapter1.SelectCommand = objCmdSelect 'Pass the Select command to the adapter.
Dim objDataset1 As New DataSet 'Create new DataSet to hold information from the worksheet.
objAdapter1.Fill(objDataset1, "TextData") 'Fill the DataSet with the information from the file.
Me.DataGridView1.DataSource = objDataset1.Tables(0).DefaultView 'Build a table from the original data.
conn.Close() 'Clean up objects.
Catch ex As Exception
MsgBox(ex.Message).ToString()
End Try
I hope this helps.

hi there, i'm new to vb 2005.
i'm trying to move an image around the form, as usual, the image flicker.
i set the double buffer properties to true, but nothing shown.
my draw code as below:
Graphics.DrawImage(ball,X, Y, 50, 50)
thanks for it
|

You have to put your drawing code in the Paint event of your form. Anywhere else and you're pretty much wasting your time.
The form gets invalidated, meaning that it needs to repaint itself. There are several things that can cause a repaint, such as dragging another window acrossed your form, or calling the form's Invalidate method. This forces Windows to schedule a repaint of your form.
You might want to setup a Timer on your form, setting it for say 100 milliseconds (one tenth of a second). Handle it's Tick event, and in your handler, update the new position of your object, then call the form's Invalidate method.

thanks a lot Dave.
i did put in in the form_Paint, i'm trying to trigger the repaint event by a keydown event. i call invalidate inside the keydown event, but the graphic still flickered.
|
|
|
|
|
How did you set the double buffer and where did this code get put?? Also, what does the painting code look like?? What does the keydown code look like??
|

i think i get it finally...
thanks a lot

I'm using the following code to get a list of databases on a Microsoft SQL server. In this case you supply it a user name and password, but is there a way to tell it to use windows authentication instead?
Dim sqlserverlist As SQLInfoEnumerator = New SQLInfoEnumerator
sqlserverlist.SQLServer = Me.ComboBox1.Text.ToString.Trim
sqlserverlist.Username = Me.TextBox1.Text.Trim
sqlserverlist.Password = Me.TextBox2.Text.Trim
Me.ComboBox2.Items.AddRange(sqlserverlist.EnumerateSQLServersDatabases())

use microsoft sqlserver connection info dll files
private static Server srvSql;
private static ServerConnection srvConn;
void ReadDatabase(string _ServerName)
{
try
{
srvConn = new ServerConnection(_ServerName);
srvConn.LoginSecure = true;
srvSql = new Server(srvConn);
foreach (Database MyServer in srvSql.Databases)
{
cmboDB.Items.Add(MyServer.Name);
}
}
catch (Exception DbExp)
{
MessageBox.Show("Error in Connection !!!!", "Database ", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
Check this section
// Log in using SQL authentication instead of Windows authentication
//srvConn.LoginSecure = false;
// Give the login username
//srvConn.Login = txtUsername.Text;
// Give the login password
//srvConn.Password = txtPassword.Text;
Hope it will help you a lot
