Looping About Simple Login Form?
Feb 17, 2010
Public Class Form1
Private Sub cmdLogIN_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLogIN.Click
Dim count As Integer
count = 0
[code]....
so this is the problem our professor gave us. the user given a chance to log-in correctly 3 times, assuming that a user log-in his/her password incorrectly there will be a loop, counting its no. of attempts. and if it exceeds to 3, there will be a msgbox assuming "you log-in incorrectly 3 times" etc. here in my code it counts but the msgbox ("try again") shows 3 times.

I am trying to create a form which will be fed by an underlying database to create multiple form fields for each entry in an underlying database table. This is for a program to monitor patients under anesthesia, and prior to surgery, the doctor will choose which monitors they will be using. Then, on the actual monitor screen which will pop up every X minutes, there will be a text box and a check box for each chosen monitor. I am relatively new to VB, so I have tried to illustrate what I am needing but using the logic that I know from my previous life in PHP.
I am using DevExpress's layout control to place the form fields, so that is the code in the middle of the first loop (on_load), and I know that part works, I just need to know how to name the fields and then recover those fields and commit the values to the database. (the text boxes are added to the database, the check boxes are used to determine if an entry is made for that monitor- i.e. at the end of surgery if a monitor is turned off). I know that my syntax for naming the fields is no where close to correct, and it probably would not work in PHP, but I remember doing something like this in a PHP application I built long ago. [Code]

I'm trying to login to the mobile login page for hotmail.com. I want to login to each account, I have them in a multi-line textbox1 in username : password format (no-spaces) on new lines. It loops through all the accounts before the page is even loaded. and when the page has loaded, it logs into the hotmail login from the last login details at the end of the textbox, instead of going from first to last. It's not clicking submit button either, its just showing the username and password looping in the inputs. Not submitting at all. The submit button code is right. I know it works. So thats not the problem.
Here is my [URL]

The login box is the first box to appear, but after I successfully enter the right username/pass combo it goes to the next form, but the login form stays open as well? I've tried doing this:
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
Dim username As String
Dim password As String
[code]....
However, after I click Login it closes down both windows. I've also tried LoginForm.Close() but that comes up with an error.

unfortunately searching the web i cannot find a decent example that allows me to loop through a winform to make sure comboboxes items are selected.basically what i would like to do is check the form if the comboboxes have been selected if not then highlight them yellow and set the focus on them.

I have some code that I want to apply to many objects (Pictre Boxes) and I was unable to loop through the objects via a For loop and am currently forced to copy paste the code for each Image Box.
The Pictre Boxes are named compAlien1, compAlien2 ... compAlien9
Is there a way to do something similar to this:
For i = 1 To 10 Step 1
compAlien[i]... #code#
Next i

I have created a customised checkbox control (only the text and border appearance has been modified), and wanted to loop through them in a User quizto see which have been checked and are correct. I have used the Tag property (set to 1 or 0) to identify incorrect answers, and tried to loop through with the following code:For Each thing As GMAW.MyCheckBox In currentParent.ActiveMdiChild.Controls

I am trying to find a way to use the UseCompatibleTextRendering properties on each control on my form. However, it does not seem to be an option when i use the following code below:
For Each ocontrol As Control In Form1.Controls
ocontrol.UseCompatibleTextRendering = True
Next
ocontrol does not seem to have that option but has all other options for the button. If i do Buttion1.UseCompatibleTextRendering = True then it works just fine.

I did a quick net search and found this which works great for looping through all the buttons to disable them. These buttons are located right on the form.
For Each ctlControl In Form_BLAH.Controls
Select Case TypeName(ctlControl)
Case "Button"
ctlControl.Enabled = False
End Select
Next ctlControl
However...when I tried it on a form where the buttons are contained within a Table Layout Panel it does not work.

I am converting a program I wrote in VB6 to Visual Studio 2010 VB.Net and have run into a problem. I am trying to cycle through 20 form elements on a form that all have the prefix 'chkCustomerItems' and then have a number 1 to 20 behind them. I am using this with a database lookup so that it there is a database entry it then applies the database item name to the checkbox's text field and turns visibility on. Here is the code I wrote:
ConnOpenClose()
Rs = New ADODB.Recordset
Sql = "SELECT * FROM CustomersItems;"
[Code]....
When it runs, I get a NullReferenceException error. This is basically the code that I used in VB6 (with some changes for .NET infrastructure).

Well I'm working on a kind of GameGuard for my private server. Ok so, I want to loop a code, I dunno if I should use Console or Windows Form Application...I dont know how to explain but I'll try doing my best to make this understandable.

This code below would simply kill the windows name "Cheat Engine" program if its opened.[code]But If I use a console application, How can I make this code loop every 5 second or so? What would I need to add in this simple code to make it loop every 5 seconds and until the console is closed?
