In my project i have 4 Forms including main form. Form2 is open through main form then Form2 remain active until user close Form2.Mean to say Form2 not allow any other form active until user closer form2.
View 3 RepliesOn my program I am trying to make a form that would activate the program.I have the activation codes but when the user enters the activation code in a text box, is it possible that it would erase that activation code or wont accept that activation code again after being used once. Then if the program accepts the activation code can it open the main form (form1) and if the user closes the program and the re-opens the program, is it possible that the activation form doesn't open again and instead, going to the main form. I have this password code:
Private Sub textbox4_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MaskedTextBox1.KeyDown
Static WrongCount As Integer = 0[code].....
Then can there be slashes every 4 characters in the text box?
I am using VB.Net for my Windows application. I will open two child form from MDI. Both forms will open. Now if I will go from form1 to form2 then Activate event for form2 will not fire.
View 1 RepliesI'm trying to make my application become the active window if it currently isn't as soon as the mouse enters the main form of the application (so there is no need to click the title bar of form itself to make the window the currently active one if it's not).
It only sorta/kinda work .... I have to enter the form with the mouse 3-4-5-6-maybe 7 times ... then the window finally becomes the active one.
I know the MouseEnter event is firing each time the mouse enters the app, but the main window isn't becoming active most of the time.
Private Sub frmMain_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter
rtbStatus.AppendText("Just got a frmMain.MouseEnter event" & vbCrLf)

I am having three forms
1. Main page
2. Input page
3. Output page
I want load event to be activated whenever coming from Main page to Inputpage and activate event when coming from output page to input page.But what i am getting is that only for the first time load is activated and for all other only activate is called.
I have a program where the main form is called (shown/activated) via a keystroke combination. When the form pops-up, I've set the focus to a textbox to begin typing right away.
When the keystroke event occurs, I have:Me.Activate()And in the Form_Activated event:
Textbox1.Focus() Simple right? It works the way I want it to, even after I've compiled and run the EXE, but ONLY if Visual Studio 2008 is running. Once I close my project in VS, with the program still running outside VS, the form is shown, but input focus is not set to the textbox.
Input focus is however still set to whatever it was previously, like a word document for example. My form will be topmost, but if I attempt to input text, it would still be entered into the word doc. why having my projects' source open in VS has anything to do with running the compiled EXE of said program?
I've even tried API calls to SetForegroundWindow and ShowWindow with the same result.
My VB.NET app supports several kinds of MDI child forms. Some kinds, but not others, are 'troublesome' -- they cause the focus mechanism to become weird. Once a 'troublesome' child form has been opened, NONE of the MDI child forms will become activated unless I click on either the title bar or the border. Clicking in the client area does not activate the child form -- its title bar remains gray, and it does not receive Activate or GotFocus events. Strangely, however, the clicked-on form actually DOES receive the focus, because its controls receive mouse and key events. Only the Z-Order and the highlighting do not change.
Once this problem develops, it persists even after the 'troublesome' form is closed, and it affects child forms which are opened afterward. However, if ALL of the child forms are closed, the problem clears up, and new child forms behave normally -- until the next 'troublesome' form appears.
I have no idea why one kind of child form is troublesome, and others are not.
I have a form with some buttons i built in visual studio basic 2010 When I left click a button it uses 1 value...but I want to be able to right click the same button and it use a different value i cannot find anywhere how to activate the right mouse button so it presses the buttons on the form so it use the different value i specify.

View 3 RepliesLoad , Initialize , Activate . What's the difference among them ? Up to now I was used to the classic VB6 events , but it seems that in .NET they are different . I was used to these ones :Load / Initialize : both the first step before showing a form . One appeared in VB6 , the other in VBA .Activate : triggered when a form is selected .However I thing that now , not only they differ , but they also come in a different order ...
View 34 RepliesI've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

View 2 RepliesI have multiple forms and have multiple declarations that I need for all the forms, is there a better way than declaring them each time on each form? Can a .dll do this, if so does it require the .dll to be a seperate file than the final .exe file. Or is there someway to reference the variables on other forms?

View 9 RepliesI am creating a web browser in VB 2010. I have a search box, and I want to make it so that when I press enter in the text box, it searches. [code] The problem with this is that when I press enter, there is this annoying "beep". I don't know where this comes from. The only thing I can think of doing is making the event activate the search button, but I don't know how to do that either. How can I fix this?

View 6 RepliesI'm now working on a domainchecking application for about 2 weeks and it is in the final developement phase.There is a my.settings that is, by default 1 to indicate that it is the first time starting the application. If it is the first time, the settingsform will show up to activate the application with a serialcode. This works fine. If I start up the app again, it doesn't show the settingsform again because my.settings.firsttime was set to 0.
After 1 cycle of the timer, which checks all the domains,the line: application.restart is being executed. Then **** happens...It shows up the welcome-message again and asks for activation.By check,I put a button on the settingsform which shows you the value of my.settings. firsttime. and ***... It is 1, like magic, it changed itself from 0 to 1. The same problem is with the indicator of the activation.Is the problem caused by application.restart? Is there alternative code for restarting an application?

had a quick question that I dont think is too difficult, the solution just isn't too apparent to me.I put an option in my program that will allow a user to redownload a setup file and repair a program installation and I wanted the program to automatically launch the msi file and pass a command line arguent to use the repair function in the installer.This code works perfectly to launch the installer, but the user has to manually click repair.
View 6 Repliesi would like to know that is there any way to activate a button with the Ctl and a key combination
we can do it with Alt and the key combination but my client is asking for ctrl & the key combination i have searched a lot but failed to find anything.
secondly :
i have used the alt & key combination for my buttons but the prob. is unless and untill the user presses the alt key the key combination is not highlighted. i have seen progs. where the key that is used for e.g. i have given &Add then the 'A' key is highlighted always with the underline. but when i am doing it by giving the name as &Add unless and untill the user presses alt the underline under A doesnt appear. do i have do more than just giving "&Add".
