.net - Scale Object Size Viewport-> Preview?
May 28, 2009
I toying with a project where I can position objects runtime on the screen. I also have an small "preview"-window, where I want to see the outline of the objects.I have an object array who have size and location on the "scene". Now I want to loop through my scene-objects and create one picturebox in the preview-window for each object in the "scene".
So, I have the size of the "Scene" and an array of the objects that are visible on the scene. Every object have an size and location mapped to the scene.I also have a preview window that have an dynamic size. How do I create a preview that scales down to the preview window? To make it easy, I loop through the scene objects in the scene and create a picturebox on the preview-form for each object, that uses the preview-forms size to do the scaling.

I need to draw a world map. I got necessary coordinates.I can draw it on a picturebox. To zoom in/out, I multiply the coordinates by a scale and draw them on the picturebox. At the same time I change the size of the picturebox according to scale.Now my problem is, it seems that the picturebox has limitations in size. I can't make it bigger than 32767.

what is the size of the object oA?and what if Class A and B contain methods?(I meant the size of object)what if inherited class B contains overridden methods?(size of object)what if inherited class B contains variables with same name as in Class A?(size of object)I need theoretical answer. Does those access specifiers Private,Dim,Public make any difference in allocating memory because of their different scopes?On what basis memory is allotted for a method? etc.

I want to modify the default Object text size for all objects I place on my form. When I am teaching, it is hard to see the text on the objects. I have changed the code area to 16 pt, but I have not seen how to modify the default font size of the object. They all are 8.8 pt.

I know VB is still very popular, but does Microsoft put the same effort into developing VB as they do for C#? Will VB eventually fade away?

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

In VB.net 3.5 SP1 I have a Windows Form with three DataGridView controls. One DGV takes up the whole bottom half of the form. The other two share the top half and are side-by-side.
I'd like to have each DataGridView scale appropriately. More specifically I'd like to have column widths and row heights adjust to the size of the form. Then I'd like the cell font to auto-fill based on a change in the cell size.
I've used the Dock property for the controls to scale to the size of the form. How can I get the rows and fonts to utilize the increased form size?

Is there a way to scale a report to fit in the printable area? Like Adobe Reader. My reports are in A4 size, but they're to close too the page borders. I bought a new printer, and the printable area is smaller than the old one, and there are some cuts in the report.I didn't change the paper size or whatever, just the printer.

I am on a project helping to analyze the load a VB.Net WinForms application can take. This app has been in production for several years and has many many products on it. We plan to add more products but see the client footprint rapidly increasing. This is contributing the degradation of performance on the system overall.There is duscussion that moving the UI intensive portions of the app to ASP.Net it will reduce the client footprint and solve many of our issues.My question which of the following will scale better in terms of performance and load? ASP.Net(VB) Web based architecture VB.NEt WinForms 3-tier architecture

my final year project title is monitoring weight changes in digital scale / indicator.i bought one digital scale online from A&D in order to test out my system.however unlikely other device (GSM MODEM, RFID...) there are no drivers or libraries (DLL) from this device.. with only the digital scale and (rs232 9-pins to usb convertor i bought) i was like lost wondering how to get communicate with the device.i have been search around in the internet for similar post.. but there are most likely dealing with the data receiving already. is there any journals or manuals for references? i willing to study over this and not simply ask for full codings.
- how to communicate with the device (serial port communication)
- is there any driver / libraries need to install bfore everything?

i would put this here maybe someone would be in the know.Waiting to here back from the company also.At work we have a truck scale and it has a control that reads the weight.Model of the control is Toledo Scales Model 8530. The control has a serial cable to communicate with.I am trying to figure out what command to send to it to get the weight back.I have connected to it with a serial monitor and i dont seem to be getting any information back so thought maybe I had to send something to it.Right now we have a 3rd party dos program that is communicating with it that i dont have the source to.
I dont know if i could just bypass the control and connect to that serial cable or not,,, i would need to find an adapter if so.Ok probably shot in dark but thought what the heck this is a smart group

What I have managed to do is currently display a chart with 3 bars on it linked to textboxes what have numerical values in them when the form is loaded. i.e TextBox1 has an initial value set in it's properties of 10, TextBox2 has a value of 20, TextBox3 has a value of 30.
When I run the program the graph displays these values correctly.
I have also got a button, Button1 which when pressed will plot the chart again, (so if I manually change the values in the TextBoxes after the form has loaded), it will display the new values via the bars.
The problem I have is that if if once the initial values have been plotted when the form loads, i.e. 10, 20 & 30, the Y axis of the chart has a maximum value of 35, so that all the initial values for the bars are shown. But if I change the values to say 15, 30, 80. and then press Button1 to update that bars to thier new values, the bars change but the one that show's 80 can not been seen fully as it goes off the chart, as the Y axis still only shows a maximum value of 35!
Does anyone know how to get the chart to resize to be able to display all the bar values within the chart each time the values are changed and the Button1 is pressed, whether it be reducing the graph for smaller values or enlarging the chart for higher values?
I am not 100% sure I am going about it in the correct way as I have not got any experience in using charts and am having to stuble about the net trying to find basic example code of how to setup and use a chart
My code so far is:
Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a VB.Net application with a datagridview consisting of several columns. I would like to be able to increase/decrease the cell font size when the user resizes the cell so that the value fills the cell. I do not see a property that would do this and wonder if there is one or if there is some algorithm by which the appropriate font size can be calculated based on character count and cell width.

Im craeating a dart scoring program (to use myself in my dart room) and want the user to be able to click in different areas of a picture of a dart board to register the thrown darts.
This program will be resizable, so the picture of the dart board can change it's size when the user change the program window size.
Im using a list of polygons(pointF-arrays) to map up each area and run some calculation to see if the mouse click is inside the polygons area, but how do I scale those polygons correctly when the picturebox is resized? My polygons are hard coded to map the dartboards area of the picture at a specific size.[code]...
