The problem is that for VB6, the default was "ByRef", but for VB.NET, the default is "ByVal".

Hello all, i have been making a few Visual Basic Applications as a bit of a hobby. Is there anyway to make an application read some files that contain code and have a program act accordingly. in other words have a add-on/plug-in system for a program.
Any help is appreciated! thanks!

There is a namespace in .Net called CodeDom, which can be used to compile and run code on-the-fly so to speak. If you google vb codedom you should get plenty of hits with a good tutorial.
Good Luck

Hello;
Please don't bother to answer this query. I found out the culprits - the same variables declared globally.

looking for usable code sending attachment with winsock in vb6, I don't know how to encode and send. anybody give me a post ? Thank you so much!

VB6?? You're not going to find it here. VB6 was declared dead years ago. Not surprising considering VB.NET replaced it over 10 years ago.

I have a program .net, and a mysql database. My problem is how to compile the database and my program into one. Please help me,,,,
|
|
|
|
|
You can't.
.EXE's, when running, cannot be written to, which would make your database read-only anyway.
On top of that, the MySQL engine doesn't support reading a database inside an executable.
Your database must be a seperate file.

Hi All,
I have a database called cohort in sql server 2008 r2 express with a table called school with the following fields; schoolname,schoolcode,zone,district,division.I also have vb 2010 form with five comboboxes.Now my question is how can i link comboxbox1 to table field schoolname,combobox2 to schoolcode,combobox3 to zone,combobox4 to district,combobox5 to division. And how to apply filter in combobox.For example if i select a particular division in combobox the next combobox for zone should only display zones for that particular division etc. I have tried to add data source to my vb application but cannot access it. Is there any coding that can substitute data objects on the form. I have managed to write a connection string for the database.

i would love to change windows button to keep pressed when i press it and back to the normal state when pressed again.
does windows button support dat? 
|
|
|
|

You could use the FlatStyle options, Unpressed is Standard, Pressed I believe if represented as Flat.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Button1.FlatStyle = FlatStyle.Flat Then
Button1.FlatStyle = FlatStyle.Standard
Else
Button1.FlatStyle = FlatStyle.Flat
End If
End Sub
Hope this helps

Take a CheckBox and change the Appearance property from Normal to Button and it will behave exactly as you want. Respond to the CheckChanged event to find out when the 'pressed' state changes.

Hi!
I would like to know if the Copy to Output Directory property can also
be useable in source code when it comes to all file types?
So far, it has its use for components and web applets.
Can this be done in source code?
Thanks in advance for your responses.

What options do you see when you view the properties for the source file?
|
|
|
|
|
What I'm trying to ask does the "Copy to Output Directory" property is included in the Intellisense and then a user tries to assign the property to one of the three values: copy always, copy if new, do not copy. A user would assign the property to the value, Do Not Copy.
Any questions or comments?

There is no intellisense attached to files in the Solution Explorer window. A simple test (mouse over) should confirm it.
