Im am also trying to see everytime i push button 3 it will hold shift down for as long as o dont let go of the left mouse button but when I let go of the left mouse button it will let go of button 3 and shift will be off O.o. Is there a way to do this?

I have a form with two seperate charts placed on top of each other.I am trying to set up a toggle button that works in sequence i.e. loads second graph over first on click. When clicked the second time it loads the first one and so on.I realise i can do this by making one visible then making it not visible but i am having troubles with the circular click requirement.

Imports System.Data
Imports System.Data.OleDb
Public Class Form1
Dim con As OleDbConnection
Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.

I have my main form then a progress bar form that is shown when the program is running. I simply want to keep the progress bar form on top of the other form and make the other form so it can't be changed.
I've tried form2.showdialog, but that stops the code in the main form from running so it's no good.
form2.show(me) just keeps form2 ontop of form1
me.topmost in form2 does the same as the last thing
setting the form1.enabled = false isn't something I want to do since you can't even move the form when it's like that
So really I'm at a complete loss here
also how can I get the progress to start in the center of form1? There is a setting in the form properties but is doesn't seem to work.

I want to lock my form to be full screen, and not allow the user to move it. For the form, I set
[Code]...
The form is full screen, but I can shift the location. I do have a dual screen system. The application goes full screen on the left most screen. This does this inside the development environment and using the EXE. What am I missing? I thought Locked is suppose to prevent the form from moving.

I have a Dialog which I'm calling via Loading.Show()Can I lock the position and location to the parent form? In such a way so if the parent is minimised or moved, the child will stay centred to the parent?
I was using ShowDialog() but this obviously stops the parent from being accessible. This is being used to display a progress gif. (Child is 50% opacity)
