VB2008: Form1.BackgroundWorker WONT Stop Form1.Timer From Form3 Click
Sep 9, 2011
Using VB 2008:Situation: A Form1.BackgroundWorker calls a Form1.subroutine. That sub starts a Form1.Timer with Me.tmrOK_BlinkForm.Enabled = True...fires Timer code in event: Public Shared Sub tmrOK_BlinkForm_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmrOK_BlinkForm.Tick
Form3.Visible = True
Form3.Label1.Text = gNowButtonDispText
Form3.BackColor = Color.White
Form3.Refresh()
[Code]...
There must be a way to do this, I just need the correct BackgroundWorker Syntax send Stop commad to Form1.Timer from Form3.Click_event...all inside a Form1.BackgroundWorker thread started in Form1.

IThere's a button on the toolstip that's always enabled for form2 so they are always able to search the database.When a user is on form1 and selects the link button. They are taken to form2 to select criteria to search. On Form3 they choose 1 item in the grid andcan select the Link It button on the form to link the 2 selected grid items (form1 and form3). Since form2 and form3 are available at anytime.my problem is knowing when the Link button on form1 has been chosen and after a successful link to not allow anymore links. Technically, they could pull form2 up via the toolstrip or an existing form2 window and Link as long as Form1 is on the screen but I do not want this. It's as though I need a global variable to set to True/False.

I need to be able to start with Form1, move to LoginForm, then back to Form1 taking 2 variables and the "values" they have in the LoginForm back to Form1 and using the variables. I start with the main form (Form1) and have the user enter some information. Once they click OK I have the LoginForm open. After they enter their credentials I will check to make sure they are legal users, then go back to Form1 (here is where I need to take the Username and Password with me) to log onto a server using the same credentails from the login form.

I have two forms. Form 1 you click a button, and it opens Form 2. Form 1 is still open.
When you click a button on Form 2, I want to run a Private Sub that is on Form 1, whilst Form 1 is still open.
The idea is that the data i've entered on Form 2, once I close this form, I can continue working with Form 1 with the updated data without having to close and re-open it.

MDIform contains Form1. Form1's MDIParent is set to MDIform Form1 has a button on click that opens Form2 as a show dialog. I need this Action.Form2 has another button that opens Form3.Is there anyway that I can make Form3's mdiparent the original MDIform by passing Form1.mdiparent value to form2 (without actually setting that value) that then passes it to form3?

Using 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?

I want to capture Form1 window, not what is on top (what I actually see).
Dim screenshot As System.Drawing.Bitmap
Dim graph As Graphics
[code]....
It captures what is on top, for example: I have firefox on top, so in myPic.bmp will by firefox, not Form1 window. So, how can I do that when some programs are on top, it captured Form1 window?

I may have corrupted my Visual Studio Software. I have two problems which may be related. The first is when I open anew project, I can't change the name of the form. I enter frmXXXX and it returns a splash box indicating I may loose my programming. If I continue the program gives me an unusable form. This happens when I have not even begun to use the form. My Visual Studio is set up to work with Visual Basic only.
Secondly, when I try to incorporate events, I can not get them to function. Using the basic form set as Form1, the Load event will work, but it enters as "Private sub Form1_Load ........ Handles MyBase.Load not Me.Load. When I try to use the events: KeyPress. KeyDown Or KeyUp, I can't get them to function. They also are entered as ........ MyBase.KeyPress. To enter an event I go to the Properties Menu, and use the event enry, click on the function, then double click the function. The sub-routine is loaded into the program, but doesn't function. I am learning by using a text book that the same programming works in a demo which was downloaded.

My program has two forms. Let's call one Form1 and the other Settings. It's possible that Settings may be opened before Form1. Settings may also change some settings that need to be updated immediately on Form1. The thing is, if Form1 hasn't been opened yet, certain elements haven't been fully initialized (even tho Form1's properties can be modified since I do create an instance of the form on program load). Since these elements haven't been initialized, if Settings tries to modify them, it crashes the program.
Are there any ideas how, maybe to keep Settings from modifying stuff on a form that hasn't been loaded yet for the first time.
