I have an aboutbox1 and form1..I also have a button. When I click the button it runs the backgroundworker. My background worker then opens form1.My backgroundworker doesnt just open it, it does alot of other stuff so don't ask why im doing it like that.My problem:When the background worker opens form1, form1 is not responding.
View 3 RepliesI have a form with 3 background workers. On the click of a button all three start async. Once they all finish my program stops responding. If I run one at a time I encounter the same error.

Dim source As String = _Topsource("[URL]" & gamertag.Text)
Dim statstbl As String = source.Remove(0, source.IndexOf("<div class=""statWrap"">"))

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?

View 1 RepliesI made a simple RPG game for my project. I used windows form application. I set the background image of my form1 to a picture that is already a map. I used picture box for the MainCharacter and set it to transparent and I also put transparent background gif images whenever the keyevents.But my problem is, sometimes when I move the picture box using the keyevents, when the picture box passes through the background that has different color, you can see the boundery of the picturebox, and sometimes it is lag and cannot display the image in the picturebox. Im gonna work hard for this because the deadline of this project is next week. I am just a newbie and not good in graphics.
View 2 RepliesI 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.

View 7 RepliesI 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.
Well i meant In Form1 theres an object named NUM in which i have Stored Few values Now i want to use this Object NUM in form2 so that i can display its value in Form2.. ima unable to access it in form2.

View 1 RepliesMy 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.

View 5 RepliesIn my application I am using some sort of 'FirstRun Wizard' to make basic settings such as data path, theme settings and other adjustments before the application starts for the first time. I am using the following at Application Start to accomplish that:
If My.Settings.FirstStart = "1" Then
dlg_FirstRun.ShowDialog()
Me.Hide() 'Form1 - my main form
End If
Now, my "FirstRun" dialog has a Cancel Button and I want the application to exit entirely if that button is pressed. At first I used Application.Exit() but it looked a bit strange because my Form1 gets shown for a fraction of a second before the application closes. With Form1.Close() I can do the same thing and the advantage is that my form does not show up at all. However, I wonder if this is a save way of doing it?
this looks like to the forum I need. I have a question on somethings. My data is pulled from a local SQL sever express.

View 1 RepliesI have been converting my VB6 programmes to VB 2008, and I am beginning to regret it.According to the books that I am reading on the subject, I can call a second form from the first one. That is, when the first form code has completed, and the final line reads:
frmForm2.Show()
the second form should open and wait for input.This does not happen, the form flashes and then disappears without allowing any input, or button click.I must admit that I preferred being able to start from a module, with a Main() sub, which then read the forms, a la VB6. everything seemed to work fine then.
I made 2 form.
In form1 I have this:
form2.show()
form2 ends up behind form1, how can I make form2 appear in front of form1?
Form2.showdialog() will make form1 disappear until form2 is closed, that is not what I want.
