My asp.net page has multiple text-boxes and DropDownLists that all have required-field validators.
My site also has multiple pages that you can move between with the click of a button. (All pages have all the buttons) When a page loads and decide I want to go to a different page without entering information into the form, I click a button to move to a separate page and the validation pops up and I can't change the page, it stops me every time?

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

I have a module level sub that I use to clear text fields etc on my forms:
CODE:
The problem I have is in the last few lines of code as I'm not really sure how to access the text boxes contained within the tab controls (of which there are many tabs and many text boxes).
This is the closest I've got but I am getting an "option strict on disallows late binding" error on the tabCtl in the following line.

I am confused what will happen, when I disable a timer. Will it finish the process and then disable or will it immediately disable without completing process? for example
[Code]....
I want to run getMessage from somewhere else, so I need to disable timer during that time to be asured not to override anything and also before timer disable it should complete that function code.

I need to disable every control on my Form so that the user can not click or press any key that will change values of listboxes and other controls on the form. I need to be able to lock the whole Form like this because as part of the project I have to print the form 3times with 3 different colors and the only way I've been able to get it to work is with a timer. So for about 3 seconds the form is changing colors and printing itself, so in between that time the user could accidantely click something and change a value on the form when all three prints should be of the same form, only difference is in the color.I can't use disable as that will make all the controls look faded and messed up, I need a clean way to prevent anything from being changed.

After maximizing a form, if I drag the title bar, the form moves out of position. This seems to be normal in windows, since IE does it also, but can I disable this? so the form stays fixed and unmovable?

I had a form (says form A)with control on it, 2 buttons with text "View Process Flow"(Button1) and "Manual trigger Process"(Button2). Both button will load and shows Form A in Panel1 in Form1, but button1 will let user to see the action but block them on clicking on it, button2 will let User see and clickon the control.
In other software, I can use a transparency button or form block User by acess formA(so, they can see,but not click), But VB2008 transparentcy option kind of idiot(Or i dont know how to use it?)seem it just change the control back color to parent's backcolor(totaly useless, and the "tranparen key" as well)
I cant disable control cause it will stop the animation, only ways i can think off is add in a IF statement in every button, so it will do nothing when viewing = true.

Problem: Form hasn't fully initialize but shortcut keys can be usedDetails: Launch an mdi child with database access retrieving data, and user is already using the shortcut keys while the data is still been retrieve which results to error since object hasn't fully initialize yet.
Goal: Hinder user from using shortcut keys by disabling the keys at initialization then enabling it after all objects are good to go.
Another Situation is:A form with a gridview and a button.I got a hotkey that when press, handles a gridview getfocus event.
The problem is that the gridview is still making its instance and when press the hotkey, it activates the getfocus property of that gridview(which is still creating its instance).

I am attempting to disable the close button "X" in the controlbox of a form and keep the maximize and minimize buttons. There does not appear to be a way to accomplish this with conventional VB code or using the Form's Properties.
So I ventured into the realm of API's.
I declared the following API Calls and Constants:
Declare Function GetSystemMenu Lib "user32" Alias "GetSystemMenu" _
(ByVal hwnd As Long, ByVal bRevert As Long) As Long
Declare Function EnableMenuItem Lib "user32" Alias "EnableMenuItem" _
