I am trying to delete a customer record. In the page I have an usercontrol for address and it has some validation. I cannot delete the record since it fires the validation controls.

I have a parent form and a few subforms. When the user clicks the red X to close the form I have a dialog box open that asks the user if he wants to exit the application. I have a issue when the user clicks no the application closes anyway. I am wondering what I am doing wrong. [Code]

View 2 RepliesI have a login screen (frmLoginScreen) which links to a main menu (frmMainMenu) then to another form (frmUserDetails). Their are two possible usernames. The first one the user logs in as Admin and the password is 4321, then the second one is Guest and no password. This is the code I have so far:
Dim G As New frmUserDetails
If txtUsername.Text = "Guest" Then
G.btnDelete.Enabled = False
End If
There are no errors.
My asp.net page has multiple text-boxes and DropDownLists that all have required-field validators.
My site also has multiple pages that you can move between with the click of a button. (All pages have all the buttons) When a page loads and decide I want to go to a different page without entering information into the form, I click a button to move to a separate page and the validation pops up and I can't change the page, it stops me every time?
is it possible to disable validation of all items inside a panel programatically in vb.net?
i can't seem to figure it out.
i disabled all fields inside a panel, but they still cause the page to validate on submit.
this is what i have now:
Public Sub DisableControls(ByVal parent As Control)
Dim cCon As Control
For Each cCon In parent.Controls

Actually I have a vb.net desktop application, it's quite a large application , POS actually. It was working fine since last few days, when it started acting up. What happening now is, while running smoothly it just closes automatically, no error nothing?!?

I have aconsole application that executes 2 other processes, and then closes the processes once it's finished its work.
If the user closes the console application prematurely, the 2 other processes go rogue and sit idle (As they are expecting to be closed by the console).
Is it possible to detect when the user clicks the X or closes the console app in another fashion, so I can also destroy the spawned processes?
I'm using several forms, each requiring access to the serial port. When I switch between them the port is deactivated. The port is activated through a special library command. How can I keep the port open and provide access for the other forms? I'm reopening the port triggered by form_load for form2 but that only works when I go to form2. When I come back to form1 the form_load trigger for form1 doesn't open the port.

I've been looking around the internet and I haven't really found any solution to my problem. Is there a way to perform a function when a user closes the form either by pressing the X button in the top right hand corner? I am using a database that saves what form the user is currently looking at, and when the application is closed I want to say "offline."

I created an app and what it does is takes a screenshot of your desktop, saves it, then uploads it to ftp. After that it closes. What i need it to do is continuously do that via what ever the interval is set to. So if the timer1 interval is at 12000 then i need to to take a screenshot and upload it every 12 seconds. Can someone tell me why is keeps closing after it uploads the 1st screenshot? [code]...
View 3 RepliesI 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?
I want to retain a value in a variable even after the application closes so the next time i open the application i can get that value.It's actually an integer value, i want to count the no. of times the application has been opened. I tried using static [b] but it doesnt work.
View 8 RepliesI need to update a table when my application closes. This is with the user name of the person exiting the app.
This works fine when the user closes the form from the main menu exit button where I have written code to update the table. However if a user exits from another form the main form is not closed (as I thought it would be) and the code that updates the table consequently does not run.
I have tried entering on other forms under the FormClosing event but this does not seem to run if they click the X in the corner of the form.
How can I get that code to run when a user exits in some other way.
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

View 3 RepliesI ran out of ideas and couldn't find any reference about it so here I go... I need to keep a secondary application wich is not related to my c# project always running in background. So if this secondary application crashes or someone else close it manually it will automatically re launch again via my c# app.
I have no clue of how to accomplish this one, I mean checking if this application closes by something external to my c# app.
I am installing an app I built in VB, and am getting the error "Application validation did not succeed. Unable to continue." I have successfully built and installed this app previously. What I think caused the issue is I attached the .mdf file I have referenced in my application to my SQL Server. I then detached the database in SQL Server, opened my VB app and re-built the app. When I tried to install the app, I received the error. Attached are the details of the error message.

My question is the last code tag section above where the parameters are set for the input.If on the form there is a textbox that is required (on the db side to not allow nulls) how would you perform the validation before you tried to execute the update sql?Ex: say 'SerialNumberTextbox.Text' was empty or if you needed to have character constraints on what was typed like varchar(15) and they have 16 or more characters
View 7 RepliesI am trying to figure out how to seperate my business logic from my forms. This is my first attempt at doing this, but I would like to figure out how to handle events from multiple forms within a class. I have found myself routinely writing the same logic over and over in each form class and its time I figure out how to completly seperate out that logic in winforms so I can reuse the methods across all of my forms.
So basically I have this click event in form1:

How can i make this more efficient. So that txtMail checks for text first then @ then more text then .com or something? i,m sure you know what i mean.and textpassword is more then 2 or three chars?
What is the best method to do data validation? I want to do data validation when the user exits a control so that he gets immediate feedback. I can use the Validating event or the Leave event for that. The problem is, that if the user doesn't know the right answer, and just wants to click the cancel button and leave the form completely, it won't let him. It continues to give him an error message until he completely deletes his answer. Very frustrating. Does anyone have a good method for doing this?
