Back Color = vb White End Sub Private Sub Text1_Validate(Cancel as Boolean) Cancel = (Text1. In some applications, however, the code in the Text1_Lost Focus method might depend on some variable that has been set in the Validate event.Text = "") End Sub Now consider the corresponding VB. If the end user clicks on a different control and Text1 contains an empty string, the Lost Focus event resets the background color to white, then the Validate event cancels the focus shift, and finally the Got Focus event changes the background color to yellow again. If this is the case, the converted code might fail or behave unexpectedly.For example, consider the following VB6 code: Private Sub Text1_Got Focus() Text1.
Is there an easy way to disable all form validation when the user clicks on the "X" icon to close an application or when the user clicks on a button in the application that closes the application? Greetings from Sint-Truiden How can we do this in VB. //create two structures to hold our Main Window handle //and the Button's handle HWND Window Handle; HWND Button Handle; //this window's caption is "Microsoft Office Outlook", so we search for it's handle using the Find Window API Window Handle = Find Window(NULL, "Microsoft Office Outlook"); //the Button's Caption is "Yes" and it is a "Button".Button Handle = Find Window Ex(Window Handle, 0, "Button", "&Yes"); //send a message to the button that you are "clicking" it.VB6 controls fire the Validate event first and then the Lost Focus event; if the Validate sets Cancel=True, then the Lost Focus event is never fired.The sequence is the same regardless of how the end user moves the input focus away from the control. NET controls fire these events in the same sequence only if end users move the input focus by means of the keyword; if they use the mouse, the control fires a Lost Focus event, then the Validating event, and – if the validation fails – another Got Focus event to let the application know that the focus is again on the control. NET programs created by VB Migration Partner follow the . In most cases, the fact that the Lost Focus event fires before the Validate event doesn’t affect the application negatively. To Int64() And &HFFFF) And &HFFF0) Case &HF060 ' The user chose to close the form. I am having a problem with the validating event of the textbox in my project. When I run the project & click the "Exit" button without entering any value in the textbox then it is prompting with the messagebox to enter numeric values. Can you also please tell me the difference between Validating, Validated, Text Changed events for a text box & in which situation they can be used. Validating is fired when the textbox loses focus (although the Leave event preceeds it) Validated is fired when the code in validating has finished executing. '---------------------------------------------------------------------------------------------------- Protected Overrides Sub Wnd Proc(By Ref m As System. This will allow the user to close the form without the worry of controls doing validation from "X". In such cases, you can force the controls in the support library to behave more closely to the original VB6 controls by setting the VB6Config.Focus Event Support static property to True: When this property is True, the support library ensures that the Lost Focus event is always fired after the Validate event.
