Can't Prevent A Form Shown With ShowDialog From Closing When User Clicks OK Button

Jul 18, 2011

I have a VB.NET 2010 Forms Application which includes a form with a textbox, and two buttons which I call from the main form using .ShowDialog

Here is the handler for the OK button's click event:

Private Sub cmdOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdOK.Click

Make Form Snap To Certain Heights When The Form Is Resized Vertically?

Jun 12, 2012

I have 3 PictureBoxes on a form that are tiled on top of each other. the form has a minimum vaule of (502, 416) and a maximum of (502, 1080). because the user can select from a MenuStrip to display '1', '2' 0r '3' PictureBoxes at once '3' being the bottom and '1' being the top PictureBox. What i need is when the user drags down the form it snaps to the next PictureBoxes position, so it goes down in blocks this is what i have so far which is pretty far from working.

If Me.Height <= (1079) Then
Me.Height = (732)
ElseIf Me.Height <= (732) Then
Me.Height = (424)
ElseIf
End If

I also thought i might be able to figure it out if i new how to create a variable like this

If Me.Height <= (1079 to 733) Then
Me.Height = (732)

I know that it isn't the correct syntax but it's kind of the idea If you can make sense from my not so good description and point me in the right direction/code example i will be most grateful :)

How To Detect If Form Resized

Feb 20, 2011

I am trying to discover how to detect that a form has been resized, or rather, that a form is being resized. I need to call a sub to handle the resizing of text in relation to the new size of a form or control. I have found that setting a minimum height and width works behind the scene so I figure there must be something watching the form size but can't find what or where it is.

Certain Controls Won't Paint Until Form Resized

May 20, 2010

In VS 2005, I have a form with a few controls (comboboxes and labels) that won't display when the form loads. The controls show up as transparent "holes" in the form, through which I can see my desktop. As soon as I move the form, or left-click on the title bar for about a second (without moving the nouse) the controls render correctly.What do I need to do to get these controls to display correctly, short of forcing a resize?

Interface And Graphics :: Dock Or Anchor Controls So That They Resize Themselves Accordingly When Form Is Resized

Feb 12, 2011

we all know how to dock or anchor controls so that they resize themselves accordingly when a form is resized. It works fine till we have rows of controls on left and right size of the form. But what if have three columns (Columns as in visual sense. I'm not talking about any column control containing other controls) of controls? For example a form having a bunch of controls in the left side, a bunch in the middle and a bunch in the right. There may be a few more bunches in the middle. Now while resizing the form, I want the controls to resize accordingly as well as change their positions to make space for the previous bunch of controls that are resizing.I mean, while the user increases the form size horizontally, the controls of the second bunch should resize and at the same time they should move right because the controls of the first bunch are increasing horizontally too. When the user decreases the form size horizontally the same thing should occur in the reverse order.I can manage it somehow using nested splitcontainers but that's too cumbersome. I would like to know if there's some better way to achieve it, like setting some property etc.?

VS 2008 Invalidating Inherited Controls When Parent Form Is Resized Or Moved?

Jul 19, 2009

Pretending I have a class that inherits off Control, how would I handle the parent form's Resize and Move events within the control? I have a painting glitch that happens when the form is resized or moved. Right now in the form I just have:

vb.net Private Sub frmMain_ResizeMove(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles Me.Resize, Me.Move Me.Refresh()End Sub

But this can't be the proper way to do it, considering Refresh() invalidates all children (will be slow and flashing if the form has lots of controls). I want to basically do the above code inside the control.

Edit:This is the glitch after a resize of the parent form:

And this is what the button is supposed to look like:

Also, I experience this issue if something like a message box is dragged over top of it. How can I remedy these issues by forcing a repaint?

Prevent A Textbox From Receiving User Input?

May 5, 2010

Preferably without turning the "Enabled" property to false, because I still need to output text from it.

I made a custom control in which there is a textbox but I want it used only as an output control, for showing text and stuff. Problem is that as soon as my form opens up the focus is turned to the textbox and I cannot catch my keyboard events on the form anymore(since the other controls are pictureboxes). I need a way to make this box "unclickable" or any way in which it is impossible to attribute the focus.[url]...
