I have the following [code]...
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'.
VB2008 I have a panel in which I draw some graphics. Parts of the codes which I have successfully wrote & drawn are shown below:
Dim scaleX1 As Single = CSng(Me.pic_pcg.Width / 1.355)
Dim scaleY1 As Single = Me.pic_pcg.Height / HGT
'
e.Graphics.ScaleTransform(scaleX1, scaleY1)
[code]....
I want to add some labels and textboxes in the panel so as to add remarks & captions to certain parts of the graphics.How do I set or modify the "scales ?" of the locations of these labels & textboxes so that they will be placed correctly, corresponding to the above scaletransform/translatetransform/rotatetransform.
I am trying to migrate large data that is required for our website hosted on Azure to access. The data amounts to about 7GB. After reading few forums, I have come to know that SQL Azure BLOB Storage can do the trick for me. how we can store data in SQL Azure BLOB Storage and access it? At first I want to try to store a Test.txt file in the BLOB and access the contents of this file from our website and display it.
View 1 RepliesSo I create the model container:
Private mdbContext As PFModelContainer
Private mdbTransactions As Object
Before I did it this way:
Private mdbContext As New PFModelContainer
Private mdbTransactions As mdbContext.Transactions
Thinking maybe I was doing something wrong I changed it over to the first way, then I do:
Public Sub New()
mdbContext = New PFModelContainer
mdbTransactions = mdbContext.Transactions
End Sub
Once I hit mdbContext = New PFModelContainer it takes me over to the PFModel.Designer.vb Where it steps through the following:
Public Sub New()
MyBase.New("name=PFModelContainer", "PFModelContainer")
At which point it terminates execution of the code. This is the error it gives me on the Immediate window:
A first chance exception of type 'System.ArgumentException' occurred
in System.Data.Entity.dll
Is there something I can do to make this error go away? I tried deleting the project and recreating it with my old .edmx model that I downloaded from Mozy from when it used to work. It stopped working (as far as I can tell) after I changed the .edmx model and updated it. Maybe I did something else in the other project too, but I'm not recalling anything.This is what is in the app.config:
<connectionStrings>
<add name="PFModelContainer" connectionString="metadata=res://*/PFModel.csdl|res://*/PFModel.ssdl|res://*/PFModel.msl;provider=System.Data.SqlServerCe.3.5;provider connection string="Data Source=|DataDirectory|inDebugMyDatabase#1.sdf"" providerName="System.Data.EntityClient" />
</connectionStrings>
Should I be referencing System.Data.EntityClient and System.Data.SqlServerCe.3.5 somewhere?The EDMX property Entity Container Name is PFModelContainer and the Namespace is PFModel.
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.
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 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.

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.

View 4 RepliesFor 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 would like to create a split container with a three way split. The first split is a vertical split. The second is creating a horizontal split within panel2 of the first split container. panel1 will hold a treeview control the other two panels will hold listview controls
I think this question has been asked already in a couple different ways and I've reviewed those posts and I've tried to do what was suggested but it doesn't seem to work for me. I've tried to place a second split container inside panel2 of the first split containter. This gave me what appeared to be a three way vertical split.

View 3 RepliesI'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.

We have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.
The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.
So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...
