I have a form which contains a progressbar and a Listbox which update as the code runs through and performs some sometimes time-consuming calculations.
At one point in the code, it breaks to ask the user to enter a number using :
Usedefault = MsgBox("Do you want to use the default value of " & Default_No & "?", vbYesNo)
If Usedefault = vbNo Then
[Code].....
this works fine but I find that once the data entry is complete, and the code continues to run, the form loses focus and the progressbar and the Listbox updates cannot be seen until the code finished its calculations.
when clicking on the start button in the code below, the form seems to lose focus and I need to click the stop button twice to stop the count. (First click to activate the form, second to click the button) Can someone please explain this behavior or offer a better alternative?
I have my form set up to be able to be kept on top if the user so chooses. When it is set to be kept on top, I want the opacity to be reduced when the form loses focus. When I set opacity on init, it works fine. When I use this code, it doesn't work:
Private Sub Form1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.LostFocus Me.Opacity = 0.2 End Sub
[code]....
Maybe I misunderstand how LostFocus and GotFocus work, but according to MSDN this appeared to be what I wanted.
I have a question regarding waiting for closing a window or changing focus back to my app. What i have is an app that creates a few tables, that then puts the tables into a temp file that wordpad opens for the user to check they are correct, this is where i need help, i would like to now wordpad is open wait until the user closes wordpad or changes the focus away from wordpad until i open the next form which is responsible for using the tables and converting them into xml.
Which event should i look at using that fires when a program is exited or gets focus?
Most of my experience in Visual Basic programming is in VBA. I'm currently trying to build a VB.NET Windows application that basically consists of a form that has one button and one label. When the button is clicked, the label should serve as a "counter" that counts from 0 to infinity until the user closes the window with the "x" button. I do this by putting a loop with a sleep statement in the onclick sub. The loop iterates the integer that is displayed in the label and does a "Me.Refresh".The problem is when the window loses focus. When it loses focus (when I click off of it), the counter stops. Even when I click back on it, the counter doesn't resume.
I have a form with a "print" toolstrip button. When I click that button I run the code shown below. The print dialog box appears. The title is dark blue seeming to indicate it has focus. The main form is lighter blue indicating it does not have focus. But hovering over the "Print" button (or the cancel button) does not cause it to change color. If you click on the print button, then the color changes and the second click causes the appropriate action. Same with the cancel button. If you click on the dialog label or on the main form the only thing that happens is the print button will then become "active" and a click there then works. If you click on the main form once, nothing happens, but if you click on it a second time you get the "bonk" sound indicating you ae clicking on the wron modal. As if this isn't strange enough, this action just started recently. I made a few unrelated (as far as I can tell) changes, and discovered this action.[code]....
I have a listbox on a form and when the user selects a value and the listbox loses focus I want to validate the value the user chose. How do I call my function once the listbox loses focus?

I want to show a message box to as the user if he/she wants to save changes. The problem is that the message box shows up behind my current form, and the current form does not have focus and is disabled. I have to switch a another program/window then when I switch back to my application, it finally shows the message box. Same thing happens when I compile and run it compiled. I also tried "MsgBox" with the same problem.

I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.
From my login form, and when a correct Username and Password has been succesfull and I get a messageBox saying "welcome to your System" (Picture Below) and when I press the OK button in that MessageBox, I want to open Form3.do I add code to the Underlined code (below Picture), or Do I write a completley different code after the messageBox code.
I have a section of code in which I want to display a messagebox after a form is displayed... as the form loads. me.show messagebox.show If I don't use me.show first, the messagebox appears before the form is displayed. If I do use me.show first, the form appears, but is not always complete before the messagebox appears. Is there an easy way to poll the form to see if it is done displaying without using a timer?
I am a beginner, working on MS Visual studio 2005. I have made a form which accepts details from a user (name , age, etc.).....what I am trying to achieve is the following:
When the user enters all the details and presses OK button, a new form or a messagebox must open, displaying all the details just entered by the user.
I would like to have my messageboxes popup in the center of the parent form. When I resize and move the parent form the popup messageboxes open center screen. I have tryed searching for an answer but have come up empty. I am programming VB 2008.
I have a parent form, which can lanch a dialog box. A wrong selection in the box launches a message box with an error message. When the message box pops up, the dialog box disappears, so the messagebox is sitting on top of the parent form.Once the user clicks "OK" in the messagebox, the box disappears, and only the parent form remains.How do I make it so that the dialog box remains when the messagebox is displayed? And also, I want the dialog box to remain when the user closes the message box. The user should have the option to make the right selection in the dialogbox once the messagebox disappears.I tried to hunt for a property for the dialog box to achieve this, but couldn't find any.
Here is the code in the parent form to lauch the dialog box, and to also launch the messagebox, when the user has made a selection in the dialogbox:[code]Am I having this problem because all the code to launch the dialog and message boxes reside in the parent form? If I put the code to launch the messagebox in the dialog box, would that make the dialog box persistent when the messagebox is launched? I am putting all the code in the parent form because it can process the DialogResult.

When a messagebox pops up, how can I bring a form infront of the messagebox (or switch betwen different forms) and then bring the messagebox back again again if I want to click OK button to proceed with the remaining code?
I am having Socket server, and I have two forms. One is the main form for the server and the other one is a custom made messagebox. When a request comes to the server the main form has to invoke the second form (messagebox). When the main form is open for the first time everything works fine. But when I close the main form without closing the application and open it again and request comes to the server the custom made messagebox opens but it freezes and looks like this:
I want to create a custom form (in visual basic .NET) that will stop other process responsiveness until the form is acknowledged. It would be a nice bonus if I can add a beep when trying to access the main program UI while this form is displayed as well (like how a messagebox does).
After using a form as a replacement for MessageBox I do have a need to make it automatically adjust its size to fit its contents, is there any rule out there that we need to abide to when it comes to sizing the form acting as MessageBox?
I am thinking I could use a panel that will auto-resize and just resize the form according to the size of the panel but I am not sure that will work as I haven't tried it yet.
I've created a form with several controls to specify the inputs to my program. They include TextBox, OpenFileDialog, Button and even a user control for numeric input. When the user clicks the 'GO' button, the program begins it work. Opening several files and processing a bunch of numerical data. This could take many minutes/hours with large datasets.
What I've been trying to do is have another window/form open up and send status information to it for the user to view. The info to be displayed is varied and constantly updated as the program crunches the numbers. Many many programs do just this type of activity.
I attempted to create a second form with a huge TextBox thinking I'd just write stuff to it. I called the .show method within the .click of the 'GO' button and of course the form is displayed but control of the program's execution doesn't return until the form is closed. How to I maintain execution and have a second window/form to display status?
