View 8 RepliesWindows Forms: LoginForm And MainForm?
Jun 14, 2010Currently, I have a LoginForm that authenticates a user and it works fine. I have a MainForm, which is displayed if a valid username and password is entered. I have done this by using the following code in my LoginForm:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]...
Now this does exactly what I want except I fear it's a work around and it's not the best approach. Also, note that I am using Me.Hide() to hide the LoginForm, is there a way to show the MainForm and then close the LoginForm instead of hiding it? Doesn't Me.Hide() call creates an overhead?

View 4 Replies.net 3.5 - Run 'LoginForm' But Putting Breakpoint But Getting Error IndexOutOfRangeException ?
Jun 9, 2009Picked up a legacy VB.NET project originally written for version 1.1 of the .NET framework. I'm running Vista with .NET 3.5. I have cleared out all the original error and the project will build; it just wont run.
As far as I can tell, it is trying to run 'LoginForm' but putting breakpoints in doesn't work because the error is thrown before the breakpoints are reached, regardless of where in the file they are placed.

Calling Properties Of Form1 Into Another Form (loginform)?
Dec 1, 2009I have 2 forms, main Form1 and a loginform. When I start the application, first "Form1" is loaded and then with a button click, user can load "loginform" if required to enable/disable some features/controls on Form1.The sequence is like this:
1) Load main form Form1
2) click a button on Form1
3) Load the loginform.
4) enter user/pwd and click OK button
5) enable/disable "GroupBox" control on Form1 if login sucessful.
For this,I made a click event for OK button in loginform, so once user clicks the OK button, I want to call one function which is defined in Form1 as a Public, which enables/disables the "GroupBox" control on Form1. The code structure is like this:in main Form1, i created a function like this:
Class Form1()
Public Function DoThis() ' Function to enable/disable GroupBox control
....some task...
[code]....
I am not able to call the DoThis() function in loginform. Please suggest me with a piece of code how to do this?? remember that Form1 is my main form which is loading first.

View 3 RepliesBest Approach To Link App To Access Database?
Jun 3, 2011How to link my app to an Access database - there seems to be a number of approaches. I can add in my database via the Data Sources tab. Fine if I want to bind controls and view/edit data. But is this the best approach for queries that return an answer that is a different shape to the original table? Alternatively I can connect to the database directly (connection string, etc) and run sql queries. What are advantages/disadvantages of each approach? In terms of flexibility, is the second approach best? Also, does the second approach require the database to be added via the Data Sources tab?
