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?
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.?
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?
I am developing a science application on VB.NET. I want the controls to be edited, resized, and drag & dropped (like in Visual Studio IDE) by the user during runtime. How to achieve this functionality?
I'm trying to achieve "disabled" affect of my form when running some process. I thought the best way to implement this was to somehow paint an overlay on top of the whole form with some gradient light gray color. But it seems like using the Form Paint event paints under all child controls. Is there a way to achieve this effect? I think I have seen somewhere else where some sort of snapshot is taken of the whole form and converted to grayscale but I need the form to be sizeable still.
I have a form with a text box in a toolstrip. I would like to make the width of the textbox relative to the form size when the form is resized. The following code works fine except when you click the restore button from a maximized state.
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 :)
[code] Actually,I m doing notepad application,my problem is when ever click the form maximize button automatically form is resized .. same like that my richtextbox control also maximized. this is the my scenario.
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.
i created 1 mdi parent form as frmMDI and 3 child forms as frmMainChild, frmChild2 and frmChild3. When the frmMDI is loaded, it will call the frmMainChild and set it to maximize. At here, i treat the frmMainChild as the base form of my application. in the frmMainChild, i can call other forms like frmChild2 and so on.
and now, my problems are: 1. how to disable the frmMainChild to be resized, restored? i just want to make it maximized only. 2. when i call the other child forms from frmMainChild, i notice that it always maximize the child form. can i make the child form to be in normal window state?
I have forms in my application that I want always with same size, I define the border style to fixed tool, disabled the control box. But if the user double click in the form header the form gets maximized. There's some way to disabled this?
How can microsoft paint(or any other painting software) be included in a VB.net project? I need to used its functionalities to maipulate jpg and movie file. Is there any ways this can be done on VB.net (or Visual Studio).
Weird issue: I have application that I fire some code in the Form_Paint event for the main form, it works fine on my machine, but on other machines is not working at all.
I tried to debug the code on the other machine, and Form_Paint event is not triggered at all!
I am using windows application vb.net 2008 . In that i am open an ms paint. When i am drawing something and clicking on save changes yes then it will require for save file. I want this drawing directly comes to the selected Richtextbox
during the development of my project, i've the need to raise the paint event of a form, to make it with rounded angle.The strange thing is that, when i use the invalidate comand on it, the repaint event (that sometimes doesn't go and i don't know why), doesn't make it like i need, that is, the dimension of the side is one instead of six pixel, and the angle are rounded, but the border is not visible.
I am currently working on a small college project and I was wondering if it was possible to insert MS Paint in one of my form.If such a method exist, I would be really grateful if you can give me the code as well.
I have the following code for a gradient form below. When I step through my code it seems to fire constantly. Does this mean that it fires constantly at run-time? If so, is there a way to stop it from firing constantly
Private Sub Form1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint Dim Mybrush As New System.Drawing.Drawing2D.LinearGradientBrush(Me.ClientRectangle, Color.LightSkyBlue, _ Color.Snow, Drawing2D.LinearGradientMode.Vertical) e.Graphics.FillRectangle(Mybrush, Me.ClientRectangle) End Sub
I am currently working on a small drawing application and I wanted to know if it was possible to insert a paint application inside a form,like vertically dividing the form into two. On one side you have some literature and on the other side you have the application.This paint application just mimics the same Microsoft paint whereby you have an open and save option
Put a picturebox1 on a form2, and paste the following into form2 public class. When you run it you will see nothing untill you force a paint event by mouse dragging the form half off the screen. If you minimize - then maximise - the image dissappears and the picturebox1 does not repaint itself??? I want the picturebox1 to be "auto drawn" somehow.
Public Class Form2 Dim colr As System.Drawing.Color Dim grfx As System.Drawing.Graphics
Running a graphics effect in the Paint event of a Form. I am thinking of something like a screensaver effect, not necessarily full-screen either. Would a background worker be better suited to this idea or using another thread? I wouldn't want something that is very demanding on a computer processor. In fact, what I was originally thinking, is it possible to put a Windows screensaver program inside a Form? Installing VB6 on Windows 7
