aside from the difference mentioned below, what are other difference the two events might have and how will affect the application as a whole? What is more preferred to use and why?
Form Load:
*Do stuff*
Form shows up on monitor
Form Shown:
Form shows up on monitor
*Do stuff*
Public Class aaMyForm
Inherits Windows.Forms.Form
Added some controls. Build it, add the .DLL as reference to my other project.
In my other project:
Imports MyLib
Public Class XForm
Inherits aaMyForm
The events from aaMyForm execute correctly but the controls added to it are not shown on XForm. I have found some info about set Modifiers Protected in order to be able to change the functionality of the controls but havent found anything about why the controls aren display on the XForm.
On form load I set my datetimepicker.value = date.now
It shows up as 6/ 7/2010
I want it as 6/7/2010
How can I get rid of that extra space?

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
How can I load a form and allow it to run it's code in the form load but keep it not visible. I want it to do what it needs to but but not display.

For example - I have a combobox on a form and I have put some code in its SelectedIndexChanged event. The problem is that I want this code to be executed *only* when the user clicks on an item in the combobox dropdown. Why is it then that it gets executed when the form first loads? And how do I stop this happening?
I used to use a "FormLoading" boolean to decide whether or not the code was executed but this surely shouldn't be necessary. Is there a better way?
Load , 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 Repliesis there a form event that occurs before the load event in a winforms application? I have a winform app that can be run in batch mode and I don't want the form to load at all. Otherwise I could just hide it in the form load event but I figured there's probably a better way.

Im Using VB 2008. I have MsgBox() statements in all Mouse & Form Click events to TEST & NOTHING FIRES during Form Load when I click on Form or Button Controls !!! The Form Load event contains code for Displaying the Label.Text control many times with changes in the Text to simmulate annimation.

The end result we're looking for is a slideshow effect where a section of our main form shows a sequence of secondary forms which fade in/out on a timer.We can fade the forms in/out when they're shown individually, but the opacity setting doesn't seem to work when they're shown inside another form. What I've got, for testing, is code that should simply reduce the opacity to 10% after showing the inner form for a half-second, long enough to notice the reduction-except I don't see any change.
Dim f As New Form2()
f.TopLevel = False
Me.Controls.Add(f)[code]........
The opacity change takes effect without refreshing the form when shown 'stand-alone' but I've tried refreshing both the inner & outer form anyway, with no change.
I have two form in my application form1 and form2. Here, i want to show the form2 from form1 by using a button. And i want to reverse back to my form1 from form2 using same technique. But i want to close form1 (Not visible=false or hide) after loading form2 and same thing in reverse back also.

I have set my forms font as "Segoe UI, 14.25pt" and have just placed an single label on the form.
Upon placing the label by default it gets the forms font i.e Segoe UI, 14.25pt
i have placed the following code on the labels textchange event
Private Sub Label1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.TextChanged
Dim f As New Font(Me.Label1.Font, FontStyle.Italic)
Label1.Font = f
MessageBox.Show(Label1.Font.Name)
End Sub
Now when the form is loaded , i get a message box showing the labels font name as "Microsoft Sans Serif"
The labels font size also changes to 8 but it is italic.
Why is this happening? And why does the textchange event occur on the form load?
When the form loads I want to fill the combobox with the data present in the database. So I did the below

con.Open()

I followed the last post about dgvs and have been trying to get my dgvs to have alternate colored lines on form load. In both apps I am working on I am using dgvs to display certain things. I do not like the look of a blank dgv on a form. When I tried to add blank colored lines to my dgv, it did work, but when I loaded the dgv with a dataset, it pushed my columns to the right and I had to add scroll bars to see my data.

I can show/hide a form, but is there anyway for me to check if a form is hidden/shown? After the form calls InitializeComponent(), and activates the OnLoad Event, it automatically calls the Show() of the form. I do not wish my form's default startup mode to be Shown. I tried overriding onshown method and call Hide in OnShown. It works but this method looks pretty ugly to me though so is there anyway that I can stop the form from even calling Shown when it was first initialized?

I moved a project so I could work on it in two places. When I opened the project, I have only worked on it from one computer, my form did not show in the solution explorer so I moved it back. I opened the project and everything was there but I was not able to see my form layout in designer view. The code is there and it builds and looks right but I can't see any of my form components and I need to edit some properties.

View 2 RepliesThe MyBase.Shown event only gets raised the first time a form gets shown. How do I make something happen every time the form is shown?
View 2 RepliesIs it possible in VB .NET to find out if a form is loaded? Also, is it possible to find out if a form is shown at the moment? I think for the second issue it's enough to get the value of the property of the form:
MyForm.Visible
However, I don't know how I could find out if a form is loaded or not.
