Interface And Graphics :: Resize Event Not Fired When Form Loads?
Nov 4, 2009
Back in the VB6 days, I could count on frmWhatever_Resize() to be fired when a form is loaded. That doesn't still seem to be the case. Since my resize event is filled with all the code I want that adjusts the size and placement of things, I decided to just call it from the end of the form's load event. That has no affect. I'm guessing that the form isn't actually shown until form_load is finished?
is there some other event that is fired when a form is shown, so I can call my resize code there?

I am trying to get a label to show briefly (3 seconds) when the form loads. The following code gives the 3 seconds, but the label doesn't show. The label is set to visible in the Designer properties.[code]

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.?

How to implement resize begin and end on controls the way a Form does. I had the idea that this can be accomplished using windows messages API (WM_ENTERSIZEMOVE and WM_EXITSIZEMOVE) but most of the samples I've seen so far are for windows. The reason for this is because I have a control that needs to re-render an image. The controll is inside a split container. The split container has only the Resize event. Is there any way this can be done?

I need to let the end user move and resize objects (like a textbox or button). There are several examples that demonstrate this in VB, but not in VB Express 2008, based upon VB.net.It looks like earlier you needed to access Windows API, but these calls does not work in VB.net. I understand that these call are replaced by "native" .net calls, but I cannot find any that does the job.
A typial example from old VB is:
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
This does not work in VB.net.

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.

[VS 2010 Beta with .Net Framework 3.5]I've written a C# component to asynchronously monitor a socket and raise events when data is received. I set the VB form to show message boxes when the event is raised. What I've noticed is that when the component raises the event synchronously, the message box blocks the component code and locks the form until the user closes the message. When it's raised asynchronously, it neither blocks the code, nor locks the form.
What I want is a way to raise an event in such a way that it does not block the code, but is called on the same thread as the form (so that it locks the form until the user selects an option.)

I'm having an issue where my main form isn't updating even though I see the event fire off. Let me explain the situation and share some of my code which I'm sure will be horrible since I'm an amateur. I created a class to take in the settings for running a process in the background. I add some custom events in that class so I could use that in my form instead of a timer.

This is a working example which draws a rectangle on different location every timer_tick and I fully understand now how it's working:
Code:
Dim i, timercount As Integer
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
[code]....
Now I'm looking for a way to draw this rectangles without refreshing them every single tick. I've just started using Visual Basic and I really don't know how to call/raise PictureBox1_Paint event every timer_tick or how to store drawing data in member variables?

In my Main class I have this event which as you can see simply closes the form. It is triggered from a ToolStripMenuItem called miExit.
Code:
Public Sub miExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles miExit.Click

I've got this code which draws a line and it moves down to a point then two curves are drawn coming off of it. I need to get it to repeat itself after a short period, so there's a constant flow of lines moving down then becoming curves.[code]

I'm creating a custom form that is composed of a inner stroke, outer stroke, and rounded rectangular background. When the form is initially drawn its drawn fine without errors but once i re size it, the old form is still drawn and the new form is drawn below it but once i minimize the form and restore it, it goes back to normal (only the new form is being drawn).

I am having a problem in Form_Load. When the following code executes the form pops up with out executing any further code: Me.TblAssetsTableAdapter.Fill(Me.ITP400_IP3_ADataSet.tblAssets).
I am trying to use Form_Load to populate values in a ListBox control from an Access database table.It appears the problem was in the Compile settings. It was the 'old' problem of using AnyCPU on an x64 machine. I changed the Compile setting to x86 and the problem disappeared.

As Autodesk is going to discontinue VBA for their Inventor product in the near future I have been looking at other ways to run VB.NET in Inventor. To date it doesn't look like VSTA will be the replacement. Automation from an External VB.NET app is certainly possible, but leaves something to be desired for speed and integration. Compiled Add Ins are the Cadillac of choice but can be a royal pain to debug and develop. Autodesk now provides a lightweight VB.NET script interface called iLogic. It's main purpose is to allow extreme customization of Solid Modeling parts. The code actually resides inside the Part Model file.

how to maximize my form window and for example my list view, tool strip container etc etc, maximize with the form window. I would just create the form to my monitor 1440x900 but this will be used on several computers all with different monitor size. What I'm looking for is a quick easy way of doing instead of setting each one up separately.

I am using a MDI form and child forms. Now I don't like the standard back colour of mdi form so I got code on the net which paints a gradient colour to the mdi. So far it is working okay.Now the problem is when I load a child form or close it or do a similar activity then it causes flicker in the mdi background. This gets pretty annoying at times and you see the background flicker.

I've got a form with no borders, and I am wondering how a user would be able to move this form around. I would like it to be moved the same way a form would move by left-clicking and holding the top border. I know that's a little vague, so if you need any more info feel free to ask...

I have a Visual Studio 2005 VB project that creates a fairly simple form containing three text boxes with corresponding labels. In terms of property settings I have AutoSize set to True, AutoSizeMode set to GrowAndShrink, SizeGripStyle set to Show, and WindowState set to Maximized.
I'd like the user to be able to grow and shrink this form using the resize grip that appears in the bottom right corner. When the application starts, it starts maximized, which is what I want, and it has the typical minimize, restore down, and close buttons in the upper right corner.
I can use restore down to reduce its size, and once that's done I can use the resize grip to make the form larger, but the resize grip will not allow me to make the form smaller. Changing WindowState to Normal doesn't change this behavior.
