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).
View 2 RepliesBack 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?
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.?
View 3 RepliesI want to write a vb program to allow user to draw rectangle. User can click on a point as starting position and drag on the screen. A rectangle is drawn with the current mouse position and the starting position. The user then release the mouse as end position. When the rectangle is drawn, user can resize the rectangle by drag the border of the rectangle.

I draw some graphics on a picture box. However, I want to change the width and height of the picture box so that the drawn graphics fit exactly in the picture box (during run time, where graphics may change). How can I do this, or how can I get the region of the drawn graphics so that I can change the width and the height of the picture box manually.
View 8 RepliesI have a program where I use a picture box (pAudiogram) to display a template. Then I use Graphics (myLine) to plot things on this picture box. Some example code is below:
Dim myBluePen As New Pen(Color.Blue) : myBluePen.Width = 2
Dim myRedPen As New Pen(Color.Red) : myRedPen.Width = 2
Dim myLine As Graphics = pAudiogram.CreateGraphics

how do I draw over existing graphics drawn on the control. This is what I'm using to draw the objects:

End Sub

I'm making a plotting program. The panel (vs picturebox) is necessary because the data doesn't all fit into one screen so scrollbars are needed. I'm using graphics to draw the background layer and buttons for the data points.
When I scroll, the background is redrawn incorrectly since the top left corner of the panel is no longer the top left data point. Ideally, I'd like to prevent the background layer from redrawing entirely (after the initial draw). Alternatively, how do I take in consideration the new position of the scrolled panel in drawing the shapes & lines in the background layer?
Currently I'm working on a retro-pong game using graphics. The problem is, my code keeps drawing new ellipses every time, and doesn't discard the old ones.

I have an application that has a list of point and I can choose a tool and draw one image to different locations then remove them if I wish, and when I finish editing those images, I can then pick another tool . The images are supposed to go away that were drawn by e.graphics but they only do when I click in the picturebox. How can I hide the images or delete them from graphics when I choose another imageHere's the paint event alone

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?

View 1 RepliesI 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 have a Form1 where i can add usercontrols during runtime. I draw their appereance in the OnPaint event using the GDI+ engine. The greate part is that i want to be able to resize these images during runtime wich goes pretty well now cause i draw points in percentage of the control. Unfortunetly it is very difficult to draw nice images/drawings ect with the GDI+ engine. Is there any other way in doing this?

I am working on watermarking image.
In the below code I load the image to the graphics path using resource image and adding text on it. When I add the image through open file dialog it paints on the form with original size but I need to resize it, add it to the PictureBox, add text to it and give zoom and pan options to it and then I need to save with the original size.
When I resize and when save the image I endi up with a small image.
Here is my code:
Imports System.Collections.ObjectModel
Imports System.Drawing.Drawing2D

View 1 RepliesI am drawing lines on a picturebox - not in the paint event. I realise that if I resize the PictureBox the lines won't be redrawn - but the PictureBox is fixed. If I display a MessageBox at the end of my draws the lines do not remain on the screen. This was OK with VB 6.0. Hoe can I stop them being erased?

I am working on a snake game for my portfolio and was wondering where the best place to put the logic for drawing the snake. Should the code reside within the snake object or within the form? Either would work, but I am wondering from a business objects/coding standard perspective where such code belongs.
View 2 RepliesI need to draw several line-graphics on a form, then select and drag individual graphics to new locations. Is it possible for example to give each graphic path an identity when drawn, then select any one (via mousedown, whatever) and link it to the dragged mouse co-ordinates until released? MS Visio has exactly this ability - can it be done in .NET?

View 2 RepliesAs 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.
