I am currently using a DevExpress (10.2) Banded GridView within my Visual Studio 2010 project. It works great except I was have an area where I allow the user to choose which columns they want visible or invisible. I noticed that if I make all the columns within a band invisible the band still remains and gives an empty column in my grid. I was wondering if there is some way to automatically

What is the difference between SendKeys.SendWait and SendKeys.Send?Send obviously will just send they key immediately, but does SendWait actually wait for the message to be processed or does it also send it immediately?The function's name itself is just confusing. Which one should I use if I want to send keystrokes to a 3rd party app immediately, or is there no difference? To me, a few milliseconds is a big difference.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CheckBox1.Checked = True
While CheckBox1.Checked = True
SendKeys("{END}")
End While
End Sub
That is the code, the error is "SendKeys is a type and cannot be used as an expression."

I'm looking for the underlying Win32 API call that the DotNET Framework invokes on a SendKeys.Send or .SendWait call, or a Win32 API Equivalent to SendKeys. I've already experimented with SetKeyboardState which seems like the way to go, except that it does not raise any kind of keyboard event that causes the set keystates to register with an active application or the OS (at least not until another key is pressed; for example I can meddle with the keyboardstate before events process on a natural keystroke, but I can't invoke a keystroke programmatically).

I have a VB.Net 2.0 application, on my form I am using a Component ONE PDF reader control.I am trying to send to this control a F4 keystoke to close the navigation panel when it opens the PDF file. It is not working or not accepting the sendkey.I put focus on the control first. Code below:
Me.PDF1.Focus()
Me.PDF1.Select()
My.Computer.Keyboard.SendKeys("{F4}", True)
I have tried different variations of the Sendkeys with no success.

So i was wondering does anyone have any recommendations

I made a birthdaylist. You can store birthdays in it, and it will alert you on the day a person has his birthday. To do that the program has to startup when the computer starts up, and give the alert if neccesary and then close itself again. This all works, but the mainform is visible in that period.

Im looking for an event that fires after a user enters a tabbed page and after the datagridview on that tabbed page is painted. BUT only fires on the load, not every single time the datagridview is painted. I am making rows in the datagrid invisible to the user based on wether or not a checkbox in the row is checked.
If I do this on the Tab_Enter event it paints the datagrid before I can loop through the records and change the visible property And if I do this on the Datagridview_Paint event it fires everytime the datagrid is painted (I only want it to fire once)

I understand the properties to change a button from visible to invisible, but I need to be able to have two buttons alternate visibility when the first button is clicked.It's for a game. The first button is to "Begin Game" and on open, the invisible button that sits over it is called "Begin Again" which I would like to only appear once the Begin Game button has already been clicked. This would then trigger the "Begin Game" to become invisible.

am trying to make use of inheritance to keep consistency in my user control appearance. I created a usercontrol to use as my base design, as a platform to link to a tab as acontainer. To this I added a few framing visual items like a header panel andsome labels.I then created another usercontrol that inherits from my base control, with the intention of adding the necessary items to this derived control to build it into a complete functional usercontrol that I can associate with a tab on my main form. I want to keep the visual appearance consistent across all similar derived controls. Then later if I change the design of the base form, this flows through to the derived controls.

I'm using a richtextbox which contains some invisible text; this is so I can have the user add a hyperlink - the code inserts the hyperlink as invisible RTF text after the link text. The problem I have is trying to delete the hyperlink - if I try and set the selectionstart and selectionlength to select the hyperlink, they ignore the invisible part (which is all of it).
So, how do I select the invisible text so it can be deleted? - I have the appropriate index and length available. An alternative approach is to somehow map the index to find the location in the rtf property of the RTB and delete the text in there;

I create some files in VB.net from a master file but when I try to open the newly created file, Excel starts and nothing is displayed, you can see the outline of Excel and it's menus and nothing else. You can't do anything with excel except close the entire application. [Code] It is upon trying to re-open where it fails, outside of the VBE. I have not had a problem like this using VB6 before, so I am assuming I am doing or not doing something.
