VS 2010 : When And Where To Create Brushes (and There Graphics Tools)
Jan 18, 2012
For some reason I could never get over the look of my application, and the Microsoft controls together. Just never looked right. Nor were the controls exactly what I needed. By creating controls I can pretty much custom fit them for my application, and I love it.My question is with drawing these controls. I have 12 of them now in my current project, so I would like to make them all as efficient as possible. The biggest set back to most of them is the drawing can be a little extensive, or at least to a point where they could be more efficient. At the moment, under each paint event I have the brushes created by using blocks and then the drawing happens within them(I create all brushes first, then do the drawing, vice versa with disposing them). My question however came up when I was creating my most recent control, a SimpleList.
I experimented to see(though I'm not sure how exactly to track performance) but instead of recreating the brushes and pens etc in the paint event, I put them at the top so they're only made once, and destroyed once, rather being made and destroyed every time my control paints. My common sense tells me this is a better way of going about this but my experience can't back that up. is this the way I should be going about user drawn controls?, is there any limitations to this?(like would it be okay if I only had a limited number of brushes etc) and is the performance even that greatly impacted by making these changes that it's worth my while?
i m trying to create logigrame or flowchart using vb.net,it s possible using visio,but visio must be installed in every computer that use my application,and we need to buy license of this tool.i have searched in google,i found metadraw but it s not free. so is there any activx or any dll that will replace visio and metadraw??
I want to create a windows installer package using visual studio. It is my understanding that there was a simple way to do this in vb6, you could add an installer like you can add a new form.
How can I do this in vb.net? I downloaded and installed the Windows SDK from [url]... because it said somewhere that it could create installer packages and had tools to do so for .net
In my Zeal to get with the "Dispose" program, I implement a dispose pattern (still learning the ways and means of THAT) wherever it seems to make sense.I THINK I have the basic idea. However, I notice that, while Drawing.Brushes HAVE a Dispose method, when I call it, some sort of instability is created in Visual Studio itself, and i get the dreaded "Visual Studio has encountered an error and needs to close" splash screen, with no useable error information. SHould I assume that one should just NOT call dispose on Brush objects, or is there something I am missing here: [code]
I want to create a list of BrushInfo which has properties of a brush name and its type from System.Drawing.Brushes.[code]The code above will get me the name of the brush (p.Name) but will not get me the type of the brush (i.e. System.Drawing.Brushes.AliceBlue). How do I get the brush type?
I have a picturebox with an image in it. I want to 'select' a section of this image (like standard selection tools in other image editors) and place it in another picturebox... The piece I want to select is a square and I have the coordinates.
I am trying to do a game application similar to chess, where i need to move the game peaces(graphics) over another graphics which is the game board. using the mouse. How can I do multiple layers of graphics and control their movement(without using direct x, i know nothing about it)? Note: I have visual basic 2010 express, windows xp home
I am trying to create a floorPlan in Vb.Net Graphics. I thought i could use say 20 pixels = 1 Linear Metre
I am currently using a Picturebox 504 * 504 Pixel. Taking a little for borders the 4 pixels off width height this gives me 500/20 = 25 Linear Metre square which is okay.
But when i draw guide ruler lines which updates the lenght of the line being drawn i cannot get it to increment per mm.
The ruler is calculated at = (pic1.Width - 4) / 20. On the mouseMove Event the measurement which i show as a string increments by 40mm or so i need it per mm.
when i draw the rectangle, the moment the container refreshes itself i lose my shape or if i run the app in full screen and then into normal window mode the shape either gets clipped or deleted. I would like to create a grahpics container to always keep the shape 'alive'.
Is it possible to create a square using graphics that will not show in VB.NET? I want to use it for the IntersectsWith function to detect moving rectangles that are around objects.
I have found an example about how to create 2D Graphics in Visual Basic using DirectX here. I have created a new Windows Application, I have copied the code, but I get errors. The code seems to be OK, but the application refuses to start. I have the nVIDIA 7300LE Graphics Card and I'm using Windows Vista x64 with DirectX 10 and Microsoft .NET Framework 3.5 SP1. I have also downloaded the DirectX Redistributable Package (March 2009) in order to make my application work...
I am creating an application where when I click on an image I need to mark the place using the x and y co-ordinates given by the click and then after marking I put a red dot/circle on that spot and then I need to save this image to a file including the dot/circle I marked. I have tried saving the image to the file but to no avail, I have been able to only save the PictureBox image and that doesn't include the graphics. It is only the base image. I have tried to save it as a bitmap but have not gotten anywhere with that either. It seems whenever I call the image.save it takes only the value of the underlying image and saves it.
Private Sub BtnCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCreate.Click pointmarked = False
I am building a program which offers solutions to the travelling salesman problem (finding shortest tour between a set of cities while visiting each only once).
My program loads a bitmap image of a map into a picture box. From there, graphics which point out the cities as well as tour paths are drawn onto the map. My problem is that when the option to plot ALL cities is enacted, the user may choose to pinpoint a specific city with a separate control. When the user erases that pinpoint via an invalidation routine, though, it erases all graphics beneath it, which is undesirable. How can I make my tour graphics and city plots semi-permanent by drawing them directly on the image? I tried drawing them on a separate bitmap, but it 'covered up' the map image.
In VB.NET, I need to create an Image based on a Graphics object I have. However, there is no method such as Image.fromGraphics() etc. What should I do then?
im working on my school project to create an application with a spreadsheet form.. some forums advice me to use "Hosting Office in .NET applications" but its not what i need.. I've already tried to use the datagridview but i cant add rows..(unless the user input a data in every row). please tell me how to manipulate the datagridview for me to able to add rows and columns automatically...
I would like to know what is the best plataform for create graphics... I would like to create an apllication that have movement with graphics...I have a medium knowledge of VS2008, but i don't know if this is the best language to create graphics!
I'm in an upper level industrial engineering class in which we're learning some entry level VB programming. We're working on building a program to solve the travelling salesmen problem (finding the shortest path through a collection of cities while visiting each only once) and I'm trying to add some 'fancy' to it so I can learn some more skills. The basic program is designed to load a bitmap file of a map into a picture box and a text file with the xy coordinates of any city positions. From there, the user can plot the cities with red squares, draw a random tour through the cities, or tour the cities by always visiting the nearest neighbor not yet visited. The modification I'm working on is a method of pointing out a specific city with a black square by entering the city's number (determined from the coordinate file) into a text box.
Private Sub TxtFindCity_textchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TxtFindCity.TextChanged Dim ObjFindCity As Graphics = picShowMap.CreateGraphics Dim City As Integer
[Code]...
So far, the program works, but I want the black squares (but none of the other graphics) that are created to go away once the text box is cleared. As of now they just hang around on the screen until I refresh the entire image with a 'clear map' sub. Any suggestions on how to accomplish this?
I want to create a table as displayed in the image in VB.net. How do i do it ?? I tried LISTVIEW with Gridlines, but it has both horizontal and vertical lines, but in the image there is only Vertical lines.
I tried to create a lineshape and make it visible when a timer ticks. Also tried to set everything that would matter when creating it(border colors and thickness etc)
But still, I got no results.
Code: Dim line = New Microsoft.VisualBasic.PowerPacks.LineShape(CX, CY, ccx, ccy) line.Parent = New Microsoft.VisualBasic.PowerPacks.ShapeContainer() line.Enabled = True
I am trying to create bitmap with my text and transformation. I am sure that there is no error in my code. Because this code is worked previously. Here is my code.
I've rendered a simple rectangle for the background and a bunch of star polygons randomly placed across the form. On the form is a picturebox component which I can move around, but for some reason it overwrites the background and stars when it passes over them. Could someone please explain what is going on there? I've tried performing searches, but have been unsuccessful in finding anything useful.
