VS 2010 - Draw Two Sets Of Dots Using HatchBrushes To Create VS2010-like Interface
Aug 13, 2010
This is a followup to this thread, where I'm trying to draw two sets of dots using HatchBrushes to create VS2010-like interface. If you take a look at the zoomed image of the IDE background (blue with dark and light blue dots): that is what I'm trying to draw using GDI+. In the previous thread ForumAccount find the correct HashStyle to use (Percent20), but there is a problem: I need to draw two sets of these hatchstyles: once with a slightly darker color and once with a slightly lighter color, at an offset of one pixel downwards.
Picture 1 shows an application that I am currently writing that uses the LineShape and OvalShape out of the Visual Basic Power Packs. As I change the index in the part number combo box the A, B & C dimension change to suit the dimension in the text boxes.
Problem is the limited shapes are fine to draw a router template guide, but they are somewhat limited when it comes to drawing more complex shapes like the router bits that make the shapes in Picture 2. Is there a graphic class that would allow me to plot points and joint the dots like you get in kids colouring in books? Or something a little more adept to complex shapes like curves?
I just spotted something called the Pen Class that I might need to look more into, but not knowing the first thing about graphics. Spotted some advice passel gave in another thread to search vb.net gdi+ tutorial and it looks like the Pen Class might have potential, although I am going to have to revisit some math by the looks of things.
Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.
I need to create a timer that sets the time from an existing text file. The time format in the text file is 00:00:00 (hours,minutes, seconds). An excerpt from one of my text files looks like ClockSet = "00:49:05"
Also, if possible, when the timer reaches 2 minutes I would like the backcolor to flash between red and green.
I've been having some trouble with a draw subroutine in a project I'm working on. The last time I did anything like this in VB, drawing on a form was as simple as calling the Line() function, so I'm not clear on a lot of these things. Here's my code:
Code: Private Sub drawBox(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles btnDraw.Click Dim blueBrush As New SolidBrush(Color.Blue) Dim i, j As Integer
[code]....
The code is just meant to draw a grid of small squares across the form, using the centers() array, which is set up elsewhere. My problem is that I can't figure out how to call this sub. If I use Handles Button.Click or Mouse.Move or something like that, VB returns an error saying that Draw and Mouse functions are incompatible. I can't call it normally, because I don't have values for sender and e.
I am really exhausted because I have been trying to find a way to draw 3D sphere which is spinning and have done nothing yet.. I am using visual basic studio. Part of my project is to draw solar system which includes a star and planets rounding about it and their stem. I want to create a class that create a planet with draw function and delete function to create movement.
I have really try to find something in the network but do nothing at all. First, I have read about XNA, but the tutorials seems to be quite complicated - after all, XNA is used for creating games, I need something more simple. I decided to use the directx libraries, read a lot about them but succeed only in draw rectangle (2D).
To print a point(.) on the given position from the formulas above.
Now heres my question how do I get Visual Basic too calculate:
x= (10 x CosA)+40 y=(10 x SinA) +20
360 times i.e 0rad-2Pirad and then pass the x & y [(x,y)] point to my cursor position code so that a '.' is printed at that position. I.e I will end up with a circle made out of 360 '.'
I would asume that a loop is used and also an array to store the 360 Pi values. I'm finding it extremely hard to even get Vb to calculate the Cos of an angle.
how to draw a dot (with XY position) in the radar.
Code: ' Draw the radar plot. Private Sub picCanvas_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles picCanvas.Paint ' Generate coordinates for the points.
Ok..I think it's very simple but I'm still a begineerI'll try to make it clear I need to draw a rectangle when I click on the button..what is the required code?
Quote: Public Class Form1 Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
I am trying to draw an image from a MS Access database by use of e.Graphics.DrawImage(New Bitmap()). In my database Row 0 Item 1 holds the path to the image I want to draw.
My current code looks like this:
Code: Private Sub pnlStart2_Paint(ByVal sender As Object, ByVal e As_ System.Windows.Forms.PaintEventArgs) Handles pnlStart2.Paint e.Graphics.DrawImage(New Bitmap(ds.Tables("Track1").Rows(0).Item(1)), 3, 3) End Sub
When I run my program I get the following message in my code: Illegal characters in path how I can draw the image from the database?
Is there any way to have 2d graphics that gets made by user through manual dimensions input be bound to a text box?
Is there any way to take position 1000,600 and make that zero? Can we make graphics by inputting only the next co-ordinate and have the pc automatically draw a line from last point?
Also, whats the difference between drawline and draw path? How can I get the shape to remain on screen when I toggle between pages?
I am trying to create a UserControl in VB.net, under VS2010. I have the code for the UserControl and I would like to add it to a form. My problem is that, according to every book and forum I have seen, after I build the UserControl, it should show up in the Toolbox. It doesn't. I even downloaded code from a book, the code executes perfectly, but their TrafficLight control doesn't go in the Toolbox (even though the book says it should - and that the only way to set its properties and to add it to the form is through the Control properties). I have tried to add the control to the form manually, by declaring it
Dim myObj As New SomeClass.SomeControl
and in the Designer.vb, identical with the buttons on the form:
Friend WithEvents myObj As SomeClass.SomeControl
With both, I get an error saying
'myObj' is already declared as 'Friend WithEvents myObj As SomeControl' in this class.
And either way, I get an error when I try to look at the design:
Could not find type 'SomeClass.SomeControl'. make sure that the assembly that contains this type is referenced. If this type is part of your development project, make sure the project has been successfully built using settings for your current platform or AnyCPU.
The control by itself builds and shows up in design view (not in the Toolbox though, even though it Imports System.ComponentModel and Inherits System.Windows.Forms.UserControl and... what else ? I tried to build it in a separate project, to see if I creating a separate dll will make a difference, though I really want it in the same project.
I'm trying to create an IE addon that allows me to just switch proxy settings. I'm sure there is something like this already, but for me it's an exercise in programming and learning as well.
When i push the button,code create me a new form but i don't know where is it?I want do something with this form take on it any controls or something like that but i don't know how activate this new form?Where is this new form?
I have a program that simply checks if the account number and pass word match. And if not it allows you to create it. But i have no idea on how to create something that will hold the data and will allow the user to add and remove sets of data.
on vista trying to create a reference to a registered DLL which succeeds with VS2008 but not with VS2010 (get system cannot find the reference specified).on vista and win7 using dependency walker the DLL cannot find IESHIMS.DLL which is in the IE folder.
I am a newbie coming from vb6 trying to rewrite my program in vs2010. I have a sudoku puzzle program which has 81 text boxes as input. In vb6 I used txtTextBox to reference the text boxes in an array. I have googled around and I dont seem to find any help on how to do it in 2010. Something similar which is array based would be nice.
Tomorrow, we have to submit our project for the first review.But I had created it in VS2010 ! But in our labs, we have VS2008, where this project will be copied and reviewed by our tutor.
I know, my project won't open in that system having VS2008 installed. Is there a solution to fix this issue that I'm going to face on tomorrow ?
When Visual Studio 2010 Express Edition starts , there is always a message (a splash screen or what so ever) saying : "Use of this software should be limited to evaluation purposes only" . What does this mean ? We must not share our programs (made with VS2010 Express Edition) not even when they are free ?
So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
I'm working on a small project - a database program to track and log the progress of some experiments. I'm using VB 2010 Express, and I'm pretty much just learning as I go. I'm getting ready to learn about the data models available, and am having trouble navigating the info I find.Is it best to develop the data within the SQL CE environment, or does that require the end-user to download additional libraries/programs? Is there a better data model for my needs (not much complex data processing, but a sizable amount of records/tables)?
I'am Using Visual studio 2010 from 1 year , and it's work fine But Today when I tryed to open the Vs2010 an Error Msg was Appeared to me which is (Cannot Find One Or More Components please reinstall the application.)
Is there a straightforward way to make a copy of a VB.NET solution and continue the project in another direction? I'd think this is a common problem but haven't been able to find an easy solution. Copying the files and renaming seems messy to me. Does the VS IDE provide anything like this? Update: It's a small project on my home computer so I'm currently not using source control. I wasn't expecting to need to fork or anything. Is there a way I can do this without setting up git or similar?
i recently received a new work pc and have installed visual studio 2010 premium on it. this was installed on my old machine as well, the only differece between the two PCs being my old one was 32bit and the new one is 64bit.With that said, when i create a windows form project and drop a control on a form, double click that control, the default event code is created for me.It is missing the "ByVal" portion of the code. Using a textbox as an example, below is the code it generates. Is there a setting that I'm just missing and need to turn on? I've been using visual studio since version 2005 and i've never seen this before.
Private Sub TextBox1_TextChanged(sender As System.Object, e As System.EventArgs) Handles TextBox1.TextChanged End Sub
In the past, in C and C++ land, nested pointer dereferencing was considered, by some, to be a relatively expensive operation if executed in a tight loop.You wouldn't want to get caught with:
for (int i = 0; i < 10000000; i++) { j->k->l->m->n->o->p->dosomeworknowthatwereherewhynoteh(); }
because you might lose precious milliseconds. (Yes, I'm being somewhat sarcastic!)

i develop a account software which is also saving picture and picture size in database(sqlserver 2000) . i want to save picture size in inches so i want to get picture dpi(dpi(dots per inches) to make inches. I am using CommonDialog1 vb6 tool to save picture and get size but now CommonDialog1 doesn't get picture inches size but get picture pixels size so i am calculating inches by pixel
