In my program i have a button which shows another form
dim oForm2 as new form2
oForm2.showdialog(me)
On form2 i have a label that i need to populate from a grid on form3
[CODE]....................
I have a splash screen, the default from Visual studio. It loads up, is shown for a few seconds, then, when it disappears, the main form is loaded. Now here is the problem: the main form appears in the back, behind the windows explorer window I load the application from.
The weird thing is that this only happens on some computers, particularly Windows XP machines.I tried a lot of things like BringToFront() or TopMost = true in the on Load event of the form but nothing seems to change this.
I have an admin section of my program to change particulars. To activate this you click the admin button the launch..then type a password. I dont want people to know there is even an admin button.... anyone know how i can assign a button combo (such as ALT+B) to show and hide that RBTN so other people cant see that admin is an option
View 8 Repliesi add a rectangle and label to datagridview...my problem is that when i load the form the rectangle only shows on the last add data..how can i make all the data display in rectangle not only the last add data.[code]
View 3 RepliesI am making an app (sorta like a computer lock) that won't let you do anything on your computer until you type in the password. I am using
Public Sub w_setfocus()
Dim f As Boolean
While (1)
f = Me.ContainsFocus()
If f = True Then
Me.Focus()
f = Me.ContainsFocus()
End If
End While
End Sub
End Class
And w_setfocus is run on form1_load. The problem is, the form then never shows up.
I got a couple of issues with my windows application VB.Net. I seem to cannot set the form to be invisible before it shows up for a second, there is no option in the properties of a form and also if I set the form to visible = false before the form is loaded it doesn't work.
So this does not work:
Browser.Visible = False
Browser.Show()
and this does work but the form shows up for a second which I am still not very happy with
Browser.Show()
Browser.Visible = False
how do i save everything thats in a listbox and save dialog shows extensions like .txt .text .html .htm .url types and it writes to where you save it too also check path files would be awesome.
View 7 RepliesI have a button on my form where I'm showing a ContextMenu when the user left clicks on it, I'm actually using MouseUp right now to show it.What I would like to have happen is the user click on the button, the button stays pressed while the ContextMenu shows, it returns to normal when the ContextMenu closes (Either a menu item was selected, the user hits the escape key or they click/tab to somewhere else). Also I'd like to position the ContextMenu in the lower left corner if the menu opens down or the top left corner if it opens up. So the left edge of the ContextMenu is flush with the left edge of the button.Moreso the button staying pressed until the ContextMenu is closed.
Edit: I'm also ok with this being it's own control inheriting the FW's Button that used the assigned ContextMenu as well.
After click the ok button all controls of displaying data should be clear in dataentry form. If i enter some data in the Combobox or Textbox for saving the data into the database, If i click the OK button all controls of displaying data should be clear, B`se i want to enter next record, so how can i do this?? Is there any Refresh Property is there?
View 8 RepliesI have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
I have a button on form2 that when pressed, I want it to enable a button on form1.What I've tried is this:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Form1.Button3.Enabled
End Sub
but its telling me that the property access must assign to the property or use it's value.
Is there any way to make a button on a form momentary? I have an app where I need to have a jog button for a motor and for the life of me I can't figure out how to do this.

I was using 2 forms, the first one has general data capture and the second one is a calendar form. On Form1 I have mulitple windows controls. A Textb ox and beside a Calendar button. When I click on a Calendar Command button, it should open calendar form and once the user selects the date, the date should be placed in the text box on the form1. Identical to this on Form1 I need multiple textboxes that needs date to be captured.I cannot use a global variable for this as I need to validate mulitple text boxes. To explain this, I have a Transaction Date and Date Received. I need to validate whether Transaction date is prior Date Received or not? I dont want to use several global variables b'coz I might need multiple validations as above. Please help me on this.
View 6 Repliesvb.net experts, I am new to vb.net but I have some programming background and some experience. What I want to do is this. As of right now I have a webpage with buttons on it and each button once clicked runs a script in DOS and a the DOS command windows appear.
I would like to make a vb.net form with buttons on it that each button when clicked executes the same program. However the kicker is I want the DOS output to be displayed within the form along with a scrolling bar to the right of the window so a person can scroll thru the outputted DOS window. Does that make sense?

View 6 RepliesIs there any way to turn the damned error provider off when i try to close the form using the windows close button(X). It fires the validation and the user has to fill all the fields before he can close the form..this will be a usability issue because many tend to close the form using the (X) button. i have placed a button for cancel with causes validation to false and it also fires a validation.

I am currently working on a program that has several buttons in it lined up. Each button goes to different applications (.exe programs). The program I am making is suppose to be a fullscreen program and won't let you see any of Windows when it's running.
Therefore I want to make a "back" button that always stays on top of any application and when I push it it will take me back to my WindowsForm (startpage of the program).I am also wondering if you can make it so all .exe programs only can run ONCE. So if I press one of the buttons saying "open notepad" I want it to work so it can't open Notepad once again making it two notepads open. Just go back to the first Notepad opened.
My form has four panels, each contains radio buttons. At design time, all buttons have checked = false, which is what I want when form loads.When the form loads a radio button in one panel has checked = true
For the other three panels, all radio buttons have checked = false.I have tested this with no code in the Form_load subrroutine.How is checked = true being set for that that one radio button ?
Does The IDE somehow force at least one radio button on the form to have checked = true?
Can I force checked = false for all radio buttons when the form loads? If so, how?

View 1 RepliesI am having trouble with some code I am writing to handle an Excel spreadsheet. The idea is that the dialog box is displayed which invites the user to select an Excel spreadsheet. Once they have done that, it is opened and a separate function checks to see whether Sheet1 exists returning Nothing if it is not found. The intention being the try/catch block picks it up and gracefully does nothing. The problem is that when the function returns nothing, the dialog box is still displayed and the sub doesn't seem to exit. [Code]

Is there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.
