I have a dot net application that uses a 3rd party activeX control. And I don't have to run the .net wizard to enable it to run. I do use an msi to install it. The main thing I would be concerned about is making sure your com object is registered in the host system.

I have a VB.NET (2005) program that reads some data from an Access file, makes it available to the user on a DataGridView and does some calculations. My understanding is that if the .exe file and Access input file are moved to another machine that is running Windows XP, then the program should run without needing to do an installation like VB6 requires.
I have placed the .exe file and the Access input file into a folder and copied this file to two other machines. The first machine was a desktop, and everything ran fine. The second machine was a laptop and the error message "The application failed to initialize properly" was obtained when an attempt was made to execute the program. Both machines are running Windows XP, Professional v. 2002 with Service Pack 2, and both have Access 2003 installed. Any ideas on why the VB.NET executable did not run on the laptop?

Probably because the laptop does not have the .NET Framework v2.0 installed.

Thank you. You are correct; the laptop did not have .Net Framework installed.

Install the .NET Framework 2.0 on it. You can get the redistributable installation from here[^] if you don't have it already.

Thank-you. You are correct, and thank you for the link. One more question: the link shows three versions of the .NET framework, x86, x64, and IA64. How does one determine the correct version?

|

The x64 and I64 versions are for 64-bit versions of Windows. You'll more than likely want the x86 version.

I have a datagridview that gets its data from a bound datatable.
I want to make the column into a checkbox column
Something like this, I think, but this isn't quite it.
DataGridToUse.Columns("Active").DefaultCellStyle = Windows.Forms.DataGridViewCheckBoxColumn
thanks in advance
|
|
|
|
|
you can use the designer to change the type of column. in the designer click on the column and view its properties. you should see a property that will change from text to link to checkbox etc.
|
|
|
|
|
Oh sorry, I forgot to mention that this datagrid is being created during runtime.
|
|
|
|

You're probably looking for something along the lines of:
With DataGridView1
.Columns.Clear()
Dim newCol As New DataGridViewCheckBoxColumn
newCol.HeaderText = "Header"
newCol.DataPropertyName = "dbColumnName"
newCol.DataSource = dataSource
newCol.ValueMember = "dbColumnName"
newCol.DisplayMember = "dbColumnName"
newCol.Width = 160
.Columns.Add(newCol)
End With

Try this:
' Initialize and add a check box column.
column = New DataGridViewCheckBoxColumn()
column.DataPropertyName = "GoodGuy"
column.Name = "Good"
dataGridView1.Columns.Add(column)

Hey all
I have a problem updating AD when the value I want to pass in is empty. When I do this I get a login credentials pop up but when the value is not empty it updates fine. An example piece of code:
<br />
Dim user as DirectoryEntry<br />
Dim name as string = ""<br />
<br />
user = getUserFromAD(AccountID) 'This returns a directory entry from AD<br />
<br />
user.Properties("givenName").Value = name<br />
If I actually go to AD and modify it then empty strings are allowed.
Any help will be much appreciated, thanks in advance.

I'm not 100% sure about this, but I don't think you can't set a property to an empty, or null, value. In order to accompish something similar to that, you'd have to remove the property involved from the properties collection of the host object.
Sorry, I don't have any examples because I haven't done any AD development.

Cheers, I thought it would be something like that. I'll just use the work-around of entering a single space in when the value I want to send in is empty, then when retrieving the data I'll check for that and return an empty string to the UI.

What API? The only way to send Mail in VB.NET is through an API. The one provided by .NET would be the easiest I'd imagine.

sorry i was asking about vb 6.0

You can use a mail component.
Or use SMTP commands directly with all error handling using the WinSock control.

if you're using visual studio then you can take a look at the code snippets section and it will add code so you can send an email through smtp

Hello Frends, I am creating a client server aplication with Vb.net and sql server 2000, which reads and writes cliente information to database. I want to store the database connection string in aplication configuration file(App.config), so that when the aplication is compiled and installed at the client site, users can go to the aplication directory files and change the connection information based on the actual server name, etc.
so for application configuration file I did:
<appSettings>
< add key= "strConetionSQl" value=="Data Source=A2-02;AttachDbFilename=|DataDirectory|\Databases\interdit.mdf;Integrated Security=True;User Instance=True"/>
</appSettings>
and on the users form login button I used:
Dim strConetionSQl As String = ConfigurationSettings.AppSettings("strConexaoBD")
conn.ConnectionString = strConetionSQl
conn.Open()
so, when I debug the aplication I get this error from the strConetionSQl:
An unhandled exception of type 'System.Configuration.ConfigurationException' occurred in system.dll
Additional information: This is an unexpected token. The expected token is 'NAME'. Line 4, position 5.
