You might be doing it wrong!

[cicatrix]

Just a thought. What do you think about a sticky thread where we can assemble typical mistakes people make when start programming in .Net?

For example, literally every day a new person appears here having difficulties with:

Int(TextBox1.Text)

then some other man with vb6 background who uses Val(TextBox1.TexT).

Another person starts using default form instances and is happy because it's actually working:

Form2.TextBox1.Text = "Hello!"

Another man comes with more serious problem showing this:

Dim sqlquery As String = "SELECT password FROM users WHERE username=" & txtName.Text

Yet another new member is having troubles with the 'Cross thread operation is not valid' when he attempts to access a usercontrol member from another thread, etc

What do you think, will this forum benefit from having such a thread? If so, then what other topics can you suggest to add?

UPDATE

I'll be posting a list of topics to include. The topics so far are:

You're doing it wrong if:
(explanations fill follow later)

... you're using the Int function with a textbox to obtain a numeric value;

... you're using the Val function;

... you're using form's names to refer to their instances (Form1, Form2, etc);

... you're constructing your SQL query right from TextBox values;

... you're directly accessing form's controls from a different thread;

... you're wondering if "2" + "2" results in "22" and not 4;

... you're using the Shell command;

Please, feel free to add/discuss.
