how I can allow the program to exit while the textbox is empty but I can't figure out how it works really..it will not allow me to exit,enter, or tab out of the textbox while its empty.
Private Sub gradeTextBox_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles gradeTextBox.KeyPress

Using VB 2010 Express.I have a TextBox on a form. I want to be able to enter some text, then press either the {Tab} or the {Enter} to leave. Tabbing out seems to be the default behavior, so no problem there, but how do I get the TextBox to respond to the {Enter} key?

I added a banning function to my program, to prevent certain people from using it (obviously). It checks for their IP and hostname, and if either match, display an error inside my error form. When that form closes, close the program. In the project properties, it's set to start shut down when the LAST form closes. This is the form closing code.

I've got the following code that just does a WMI connect to a remote machine - I haven't setup any code to query anything yet but when I step through the code I don't get any errors. I get to the last debug.print statement and when I step over it the program exists. Almost like I've called a End. No errors or anything - it just exists. How come it doesn't take me back to the form? IF I comment out " scope.Connect()" then it ends the sub and returns to the form.

I have a text box in my application. When I open it, I type "Hello" and then close. When I open it again, the text is obviously gone. Is there a way now to keep the text and any changes in there rather than making the program save a .txt upon closure, and then opening it every time the application loads? Would the same code go for a checked check box, or a certain radio button, data grid view, etc. ?
View 2 RepliesI have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this.
And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working? because I am giving focus to it so whats happening or rather why is it not happening Is there a way other than exit sub to tell it to stop executing on that line and do other stuff

I've been working on two projects, one needs to have multiple forms, but when I open one form, it needs to close the sender.
But, when I try it, the program exits! I don't want it, I just want to close the form, not the app.
I tried the 'Form1.Hide()' too, but it doesn't sound good to me. There is other approach?

View 12 RepliesI'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.

Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

View 6 RepliesI'm trying to track down the cause of an annoying interface bug in an app that was ecently upgraded from VS2003 to VS2008 (the bug did not exist pre-migration).What happens is this :1) User clicks in textbox containing a date.2) User clears date3) User tries to move to another field, but can't. No error messages appear - it's as if the validation failed.Further info :1) The textbox's Text property is bound to a dataview which uses a datatable as its source. The bound field is a nullable datetime field with no constraints or default.2) The Validating event fires and the CancelEventArgs property is not set to Cancel. The Validated, LostFocus and Leave events all fire as well, going LostFocus > Leave > Validating3) I can't see any code changes relating to the control or the datasource with a couple of exceptions. The first is that this :
Me.txtRangeEnd.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.dvClientNos, "RangeEnd"))
has now changed to this :

I have a form with a textbox, and i would like validation to occur so that a blank field is not allowed
e.Cancel = String.IsNullOrEmpty(TextBox.Text)
Does not always work, because it still allows me overwrite an existing field with blank spaces, and then update.
So, my application has multiple text boxes for entering different numbers. Only numbers..
One problem I've run into is that I get an error when a textbox is totally empty. If I throw at least a zero in there, it works fine.
How would I make a textbox display "0" when someone deletes everything in the text box? I don't want it to be empty, I just want it to show zero.
