I recently added three subroutines to a form, and as a result of adding only the three subroutines, I have noticed some weird behavior in the form and I can't pin down why these three subroutines would cause it.

2. How would I open a form as Invisible and be able to still call subroutines from it?
i have a main menu on my program which has the option of registering. I have enter name and password ..and a button Confirm

what must i do? also where would this data be stored...
I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

2. and another beginner question.. how to i declare a string that spans multipe lines? i tried with the + operator like in c#, but it doesn't work.

I wana know how can i use a value from a sql table that i added from another form?It basically supposed to validate that whatever was the last recorded added in the other form(eg formA) , i must then use those same values from the sql , into another form(eg formB).If i type a value in the textbox( in formB), it basically must validate that, the value i typed in, is not the record that was enterd in the other form(formA) (the last record added in that form)
Here is my coding that i did:
Dim conmid As New SqlClient.SqlConnection("Data Source=CHETS-TOSHIBASQLEXPRESS;Initial Catalog=PlanetDiscLibrary;Integrated Security=True")

View 4 RepliesMy background is mostly Access VBA and I am having to learn VB.NET. I am trying to recreate an Access 2007 application I wrote into VB.Net. We are looking at using a hosted SQL Server so we do not have to worry about remote offices or replication. I am using VS 2008 and SS2008.My issue is that I need to create a login form in VB that with look at SQL Server DB and return a dataset record matching the username and password. There are many tutorials on here but do not match what I am looking for.I have a stored procedure with 2 parameters (@prmUser and @prmPassword) named spLogin.I need to call the sp and pass the parameters to SQL Server DB and return the complete row of data that is matched from the button_click event on my form.
In Access, I would have a form that would have the returned data and I would reference that information throughout the application by using the 'forms!frmName!txtValue' to populate forms, reports, and fields that would capture the user that created the record. What is the best practice for this?Next when the login credentials are correct then I need another form to open, which is my MDI form, if not correct then msgbox to try again.
When I add or modify controls on the form the graphics are redrawn many times over.The more graphics that are drawn the slower the machine gets.
View 1 Replieswhen i add the record it saves and returns the save message box as it should and is viewable in the database where it saves to, but it is not viewable in the text boxes when looking back at the form until i close program and re open it, then i can see the record stored in the database, it just wont update the form,[code]
View 2 RepliesI tryed to make a media player and i added a button to the form called "Full Srceen".[code]'so i get an error message : Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
View 2 RepliesI created 3 Forms (Form1, Form2 and Form3) and I added a button on every form. This is code for Button1 on Form1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.BackColor = Color.Red
Form3.BackColor = Color.Red
Me.Hide()
Form2.Show()
End Sub
Code for Button1 on Form2:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form3.Show()
End Sub
Code for Button1 on Form3:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form2.Show()
End Sub
Now, the problem is that when I click on Button1 on Form3 it shows Form2 but the Form2 BackColor is not red, it is default color, A.K.A Control Color. But I specified in Button1 on Form1 that Form2.BackColor is Red. And also if I click on Button1 on Form2 when Form3 shows it, the Form3 BackColor is also default, it is not red.
I know one way to solve it but it is so not-professional. It is that you add on Button1 on Form2 this:
Form3.BackColor = Color.Red
and on Button1 on Form3 this:
Form2.BackColor = Color.Red
It is ok in this situation but what if I have more stuff, for example if I have an option for changing theme so it has to change all labels and buttons ForeColor, what then, is there any other way?

View 6 RepliesHaving some issues with creating a simple control in vb.net.
I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)
When i then build it and add this control to a form. Some of the edges are cut off and it isn't anchored the way it was in the control.[url]...
as you can see in the second image the control has lost its white border at the right and bottom.
I have successfully added textboxes to a form at runtime. I have also succesfully added an event handler to these same textboxes. What I'm having trouble understanding is how to refer to these textboxes programmatically after they have been added. Specifically, how do I;
1) Retrieve user data entered in those textboxes without an event handler
2) Find a specific one of those textboxex later (is looping thru all controls of type "textbox" the only way)?
purpose of find is so that I can set the value of the corresponding textbox programatically, based on some criteria Here is the code (all within in a for loop, where intvararycount is incrementing to a set limit) I have used to add the Textboxes to a Panel on a Form;

View 11 RepliesTo detect 'death of player' I am using the mouseleave event of my picturebox background (background1). Unfortunately this triggers both when the mouse enters an 'evil' and the 'points' and ends the game without the player being able to collect points.
The obvious way to solve this would be to swap detection to entering evils.
Unfortunately I am dynamically creating my 'evils' and do not know how to also dynamically create subs to deal with MouseEnter. Here is my code for generating the 'evils'
'The number of evils (asteroids)
Dim evilcount As Integer

I'm struggling with an event related to my communications class.I'm calling a 'DataChange' function via event handler any time I receive new data over my serial connection. I then proceed to load that data into a DataGridView, perform some formatting, etc for the users. I'm getting a ton of problems due to the frequency at which the DataChange event is called and seems to steal the focus out of othert subroutines and functions mid-process.For example, I'll attempt to transmit data back to the serial device. After I format the data, but before I can actually call the Send function from my library the focus is directed back to DataChange and I never actually transmit my data.
Is this a problem best addressed by threading the DataChange related routines, unhooking the DataChange event before a function or routine then rehooking, or is there some basic principle I'm not implementing.
The Visual developer express outline provides hide/plus-minus signs throughout the HTML code, and it does this for Class's, but not for my subroutines in an ASPX file.Is there a way for it to do this, so I can reduce subroutines I'm not working on at the moment? I know I can highlight areas and hide, but it's kind of clunky to do quickly through many subroutines if I have 2k lines and a hundred subroutines.
View 1 RepliesI have 2 arrays X(n) and Y(n) where n can vary programmatically, no set value. I want to pass these two arrays between two subroutines.

I want to know how to prepare the arrays for the "call sub2" and how to extract the arrays in "sub2".
