1.) just handle the DoubleClick event 
you may noticed, the doubleClick event will be fired, if you doubleclick on the background of you grid, but not if you click into a cell. when you enter a cell a DatagridTextbox will come to front and catches the doubleclick. solution follows...
2.) you have to define your own columnstyle and override the onpaint-method. in onPaint differ between current row and not current row.
public Class YourColumnStyle
Inherits System.windows.Forms.DataGridTextBoxColumn
Protected Overloads Overrides Sub Edit(...)
' override and do nothing so DatagridTextBox wouldn't appear
End Sub
Protected Overloads Overrides Sub Paint(...)
If Me.DataGridTableStyle.DataGrid.CurrentRowIndex = rowNum Then
Else
End If
End Sub
End Class
how to implement a functional columnstyle is an other story

Thanks.
I'm a newbee at vb (long time user of FoxPro) but I'll try out your ideas.
When I did this type of thing in FoxPro I created a subclass of a textbox control which had code in its double click event. Then I added this textbox control to each column in my grid. Double clicking in any cell in the grid ran the textbox's double click event. This approach work well. Can I do this same type of thing in vb?

Use the Process[^] class. It's just like launching any other external executable.

Like Colin said, this is MIT research stuff and FAR beyond the scope of what anyone here can explain to you in the forums.
You're only source of information is going to be Google and sites and University classes dedicated to the subject.

I want to send an email to a number of people. The people I want to send to are stored in a database table. I want to send an email that includes a message and includes an OrderNumber which is stored in the database table. The recipients email address is stored in the database table also.
I am not sure what way to retrieve the information and to send it. I think I should read the information from the table using a sql query such as:
Param = SqlCom.Parameters.Add("@OrderNumber", SqlDbType.VarChar, 4)
Param.Direction = ParameterDirection.Output
Param = SqlCom.Parameters.Add("@MailAddress", SqlDbType.VarChar, 20)
Param.Direction = ParameterDirection.Output
Conn.Open()
SqlCom.ExecuteNonQuery()
Conn.Close()
OrderNumber = Trim(SqlCom.Parameters("@OrderNumber").Value)
RecipientAddress = Trim(SqlCom.Parameters("@MailAddress").Value)
I think I should read it using a loop and the send the mails to a recipient using the following code:
Dim dr As SqlDataReader
While dr.Read()
Mail.To = dr("OrderNumber").ToString()
Mail.Body = TextBox5.Text
Mail.From = "jmcconalogue"
SmtpMail.SmtpServer = "donegal-mail"
SmtpMail.Send(Mail)
End While
dr.Close()
Does anyone know if this will keep looping through the table and keep sending emails to all the recipients listed in the datbase table as there may be quite a few in the table?
Anyone a better way to do this?

If it is the same e-mail which needs to be send to all the recipients, then why not simply compose one string containing the recipients adresses, seperated by semi-colon's and then place it in the BCC field.
So instead of
While dr.Read()<br />
<br />
Mail.To = dr("OrderNumber").ToString()<br />
Mail.Body = TextBox5.Text<br />
Mail.From = "jmcconalogue"<br />
SmtpMail.SmtpServer = "donegal-mail"<br />
SmtpMail.Send(Mail)<br />
<br />
End While
something along the line of:
dim strRecipients as string<br />
<br />
While dr.Read()<br />
<br />
strRecipients &= dr("OrderNumber").ToString() & ";"<br />
<br />
End While<br />
<br />
Mail.BCC = strRecipients<br />
Mail.Body = TextBox5.Text<br />
Mail.From = "jmcconalogue"<br />
SmtpMail.SmtpServer = "donegal-mail"<br />
SmtpMail.Send(Mail)<br />
(note that the code is just meant to be an exampel of the idea)

Hi,
I have a class which is used to store customer information. For each customer there may be multiple contacts. How can I record this in a collection class. I've tried to do so as follows:
<br />
' CCustomerInfo -> stores one customer record<br />
Public CompanyID As Long<br />
Public CompanyName As String<br />
Public CompanyAddress As String<br />
Public CompanyFaxNumber As String<br />
Public GeneralSupportExpiryDate As String<br />
Public HardwareSupportExpiryDate As String<br />
Public Contacts() as String <---- Error here<br />
<br />
' CCustomerInfos -> collection of CCustomerInfo objects<br />
<br />
' this is how I add objects to the collection to the class<br />
' not trying to add contacts() yet as I can't declare it correctly<br />
Public Function Add(CompanyID As Long, CompanyName As String, CompanyAddress As String, CompanyFaxNumber As String, GeneralSupportExpiryDate As String, HardwareSupportExpiryDate As String, Optional sKey As String) As CCustomerInfo<br />
<br />
Dim objNewMember As CCustomerInfo<br />
<br />
Set objNewMember = New CCustomerInfo<br />
<br />
With objNewMember<br />
.CompanyID = CompanyID<br />
.CompanyName = CompanyName<br />
.CompanyAddress = CompanyAddress<br />
.CompanyFaxNumber = CompanyFaxNumber<br />
.GeneralSupportExpiryDate = GeneralSupportExpiryDate<br />
.HardwareSupportExpiryDate = HardwareSupportExpiryDate<br />
End With<br />
<br />
If Len(sKey) = 0 Then<br />
mCol.Add objNewMember<br />
Else<br />
mCol.Add objNewMember, sKey<br />
End If<br />
<br />
Set Add = objNewMember<br />
Set objNewMember = Nothing<br />
<br />
End Function<br />
The error message is as follows:
<br />
"Constants, fixed-length strings, arrays, user-defined types and Declare statements not allowed as Public members of object modules"<br />
Can anyone suggest a way to make this work? Thanks very much in advance.
Sorry for the lengthy post!

Well, you can't have any array inside a object you're using in a collection. You might want to try replacing that array with another collection to hold your contacts.

If it's a desktop application then no.
If it's a web application then yes, provided that the server(s) is a Windows Server (2000 or 2003). The Linux client is then just consuming HTML.

You definitely won't be able to run a SQL Server database on anything but Windows. If you port your application to Mono, the open-source X-platform version of .NET (there are articles on the codeproject site) then you stand a chance, but again not everything will be guranteed to work. However, there are some real industrial-strength Mono applications out there, so you can probably achieve what you want with some effort.

MySql if you want free, otherwise, Oracle or DB2...

Hi
Can anyone tell how to include autocad in vb.net
Thanks in advance
|
|
|
|

It looks like google[^] knows.
The answer is bound to be COM, so look up the COM interfaces that AutoCAD exposes, and also read the articles from the google search.

Thanks in advance

hey, if you can't find an example that work, it is because YOU don't use'em properly  suss:
TOXCCT >>> GEII power
[toxcct][VisualCalc]

What works for one person might not work for another. There is no single example that is going to show you how to do this. You absolute best resource is the AutoDesk Developers site, here[^].

Does anybody know a quick routine to convert from numbers like "1000$" to "One thousand dollars"?
I need this to print invoices
Thanks in advance

I found many source code hits on Google using convert number to words as the search terms. There are samples in Java, VBA, VB etc...
See if one of those is the right one for you.

I need explorer to open a folder so that i can view the files inside. No browsing or dialog box is needed, I just need to open that specific folder with Windows after clicking a button. Anyone knows how to do this?
Another question would be how do i declare a statement as a string if that statement has "" in it?
E.g.
Marks = "69" Grades = "C"
How do i declare the above sentence as one whole string?

I believe you double the quotes, as in
String s = "Marks = ""69"" Grades = "C"""
In C#, it's \", but I believe it's double quotes in VB.

I'd say that ShellExecute or Process.Start will do this, just pass in the path.
