when you login it is the meaning that another form opens. But as soon as the new form opens up everything closes. The code i used is this:
Public Class Form1
Public Goldhave As Integer
Public UserName2, Password As String
[Code].....
When opening a button and opening a new form as soon as it opens it close for some reason but its not giving any errors as to why its doing this now I've checked the linked linking it to the next form that's fine.
Private Sub PrintPerscription_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Login.con.Open()
sql = "SELECT Patient.* FROM Patient where Patient.Wardno = " & Login.WardNo.ToString
da = New OleDb.OleDbDataAdapter(sql, Login.con)
noOfRows = da.Fill(dsPatient, "Patient")

I developed a winform .NET 4 application that has the ability to asyncronous save image from scanner using Bytescout Scan. Anyway I noticed that in some cases (with some scanners) the scanner's GUI opens and then closes immediately after load without performing any scan. Since no error message is raised either from my code and from scanner software itself; is there some settings/tweak somewhere I should pay attention?

I have the following code so the user must confirm cancel action, however the form closes on both yes/no action.why the form does not remain active when the result = no?

Dim resultDialogue As System.Windows.Forms.DialogResult
resultDialogue = MessageBox.Show(
"Do you want to cancel the Add Worker function?", "Confirm Cancel", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
If resultDialogue = Windows.Forms.DialogResult.Yes Then
ClearDtls()
Me.Close()
End If
End Sub
i'm using exit sub when a certain condition does not meet. but the problem is that the form closes. it should not close the form, instead, it should only exit from a click event. I'm using VB2008Express Edition and MS Access at the back end.[code]
View 4 RepliesI have a form ( call it NewForm ) that can be opened from many other forms, but I don't want to have the user to run into the problem of having many windows/forms open.I want to close the calling form and open NewForm.NewForm will prompt the user for information, but if the user doesn't find what they are looking for I want to have a "Cancel" button on the form. With the "Cancel" button I want to go to the previous form.is there a way to tell which form called NewForm so I can just reopen/unhide that form/window.
View 5 RepliesWhen I initialize a new form to open, the subroutine in the new form starts before the new form is shown on the screen and so when the subroutine finishes and the MsgBox comes up, the form isn't showing.

I have a problem here I hope someone can help me out. I have this application in which I show information about workplans. It has a Main Form which show the general information and the activites that are going to take place during the execution.
The application has the ability to "attach" documents to the activities. I have created another form (and MDI form) that I use to show the documents (pdfs) when a user clicks on one of the documents attached. The problem is that when I close the form that shows the documents, it ends the application and I don't know why. It should just close and leave me again with the Main Form. Can someone tell me why is this form terminating the app. Is it because is MDI or what?
Basically, I have developed one form which is generic and display different views. On that form I have used Close button. Alphabet E is short-cut for closing the form (i.e. mnemonic functionality).During execution of the form, when I press "E" on that form, my form closes automatically. As per my understanding mnemonic works with Alt control only. I am not sure if I am missing any properties that should be set so that this problem is resolved.
View 1 RepliesSo I've got a somewhat common problem from what I can tell from the search results..I developed a program, got a beta version performing well, noticed a few small bugs, fixed the (all code-related) bugs, and now the program will open and then close immediately. I believe I have determined that the problem is not code related as I have commented outall of the code and it still refuses to stay open until I tell it otherwise. From heaforementioned search results many people have found this to be due to a ensingtonproduct, however I do not own such a product nor do I have any Kensington softwa

I'm quite sure I'm mistaking something in the EndReceive method, anyway that's the resource I've looked into: [URL]..I can't figure out why I should use a state object which contains a socket (or tcpclient etc..) variable instead of some public variables in my current socket class.

View 4 RepliesI am using VS 2008, Windows XP R3, and Visual Basic.When I open some forms in the form designer, (In Solution Explorer, right click on the form, then select View Designer) the form always opens as Edited. An Asterisk "*" appears after the form name in the open window tabs. If I open the form to just view the code (In Solution Explorer, right click on the form, then select View Code), the form opens normally. This happens for just some forms.
It always happens for the same forms, and never happens for the other forms. What I am missing in those forms where the designer always thinks the form has been edited?
I've made a Windows Forms Application that runs fine. It has some buttons that open child forms, which can simply close again without any problem. As I need the form to be in a dll, I changed the application type to a class library and added an extra project containing an exe-file that only references the main form in the dll and shows it. So far so good...
The main form is basically a tabcontrol with a bunch of controls, buttons among others. Five buttons on different tabs use the same handler to open a child form. When I click the button on the first tab everything works fine. The form opens and when it closes, only the child closes. When I click any of the buttons on the other tabs, the child form opens and when it closes again, both the child and the main form close...
I am stumped, especially since all buttons use the same code to open the child form and everything appears to be completely identical, yet the results are not. Below I have pasted the code that opens the main and child forms. I am undoubtedly not looking in the right place, but I also have no idea where to look anymore, let alone what to look for...
The code opening the main form:
Public Sub StartProgram()
'Load the form and show it
Dim frmProgram As frmMain = New frmMain

We have a window that has a text box on it that the user must enter in valid data before going on. So we have put in a message box letting the user know that they have to enter in the correct data before going on in the Leave event. That works just fine, but when the user press ALT+F4, or presses the X in the upper right corner of the window it still goes through the event. We would not like for that to happen. When we were using VB6 the same code was in the lost focus, and when the user pressed ALT+F4, and the X the LostFocus event did not fire, or acted like it did not fire. We have also tried moving the code to the Validating event, but it behaives similar to the Leave event? how to close a window, and either have the Leave, LostFocus, and Validating events not fire when the user Presses ALT+F4, or the X

I need to create a program that requires password entry. I was thinking of having a form that the user uses to set the password that only opens once (unless a button on the main form is clicked to reset the password.) once the password has been set, the form closes and another opens to enter the password and for each and every time the program is run. Another thing is that if the password has been entered wrong 3 times, the program gives a message box and closes on the ok button.
