I have a stack of 2D dicom images and want to convert to a 3D object using VB.NET. I suppose I can solve it using openGL but any clue would help a lot. Do you know a free (or at least cheap) pack to do it?
View 1 RepliesI need to construct an XML transaction of the following format[code]...
I was thinking of creating a "GetXml" function on my object that returns the XML representation of the values in the object instance.I could do all the string concatenation myself, but surely there is a cleaner way.
Is it possible to construct the name of an object (in this case, a Panel control) at runtime?
What I want to do is change the Backcolor of one Panel that is a member of about fifty panels. I can get the string of the name from the Sender in a RadioButton CheckedChanged event. So what I want to do is something like:
PanelName = sender.parent.name & ".BackColor"
PanelName = Color.Red
(I realize that the syntax above is invalid. I'm just using it to try to get the idea across.)
I can do what I need with big, fifty-element Select Case blocks, but the code is so repetitive that I was hoping there was a more elegant way.
I am going to construct a VB program that will calculate dog and cat ages, i plan to have a user interface to ask the user if they have a cat or a dog, then id like another window appear to ask how many human years of age is your dog/cat, up to the age of 20 (in human years) with that input the calculator will give you the age equivilent in dog/cat years.
View 1 RepliesNow I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.
In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..
I am attempting to combine multiple bitmap images into a single graphic object using Drawing.Drawing2D command but am noticing the image quality changes.I tried various combination of these ...
g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
g.SmoothingMode = Drawing2D.SmoothingMode.HighQuality
g.PixelOffsetMode = Drawing2D.PixelOffsetMode.HighQuality
g.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
but did not get the "perfect" quality.What I want is one image to be in one region of the graphic object. Another image to be in another region. There is no overlapping of the image regions so essentially I want an source image to be as is in a given region. I noticed an option for "CombineMode" for Drawing2D but cannot figure out if and how to use this to get what I want.
I am currently trying to get a WebBrowser object not to download flash and images. This is just to make a lightweight browser. I know this can be done within the IE settings, but i would prefer it on an application level.

WebBrowser1.Navigate(New Uri("http:google.co.uk"))

problem we have a database where some signs are stored. a user comes and shows a sign throw webcam and if this sign exist in the database then corresponding sound will be produced.so here i m doing pixel by pixel matching so if the position of sign shown by the user is different from the saved image then it would give unmatched while same sign as in the database is shown..the image of a sign is shown in attached file.

View 1 RepliesI need to construct a data array and I am not sure if I can do what I need to do given the data. I probably should opt to store in a new class but that's too advanced for now
the data describes a series of points. each point has its index in a list a boolean, binary value and a list of integers of its neighbour points. so i thought it would be three columns and the third column would store a list. can you do this?
I presume i could get rid of the column dedicated to storing the integers..

Im having some trouble to construct a Master-Details form. When I navigate through each record on the master nothing happens on the details. This is so even if there exit a relation between the two tables in the database and in the dataset between the data table. Can anyone provide me with some samples or examples of coding how to proceed?
Furthermore I have tried to programmatically create the relation but the following error occurs: child list for field cannot be created etc
This is probably a dumb question but I have to call one of 30 or so global variables by constructing the variable name to be called from another information. However when i do that it treats it as a string. Any ideas on how to make this work?eg something like this:
Public gsNewYork As String
public sub Getinfo
dim lslocation as string

I am looking for a way to read an XML file at run time and construct an Enumerator from it. I got the reading and writing all working, it's just getting all the strings to create an enumerator that's the tricky part. I could get them into a collection of strings or maybe a dictionary, but not sure how to go about converting from these into an enumerator. The goal of this is to allow users to add and delete items from the underlying enumerators and eliminate writing hard coded enumerators. My idea is to allow users to extend the program without coding. This is a Winform vb app thats not using any database but just XML files to store and retrieve things.
View 7 RepliesI have a spreadsheet with Proj Numbers: "049410-001" in column B6:B60. I have the URL to the Database: I want the links to show up in the A column with the Tag being the Proj Number "049410-001".
Also, if I could clear the A column and use it "A column" to enter the Proj Numbers and then run the Macro to enable the Hyperlinks I could eleminate the Proj number taking up 2 columns. I have 80 rows set aside for projects so it needs to go through and enable the links that have text in them.
i used =HYPERLINK(E24,B105) (E24 was another wasted cell that combined the static first part of the link, and the proj) as the formula way to do it, but I'm trying to make a Macro that does it behind the scene. but I am just getting into VBA, and I have no idea what i'm looking at when I look at a code.
I have a CheckedListBox populated with specific records from an Sql table . I want to update each record in the table, only if the checkbox checkedState = True, so far I can update all or none. This unworkable code will hopefully give an idea of what I need to do.

I have a number of image files name image1.gif image2.gif image3.gif etc upto image52.gif
I want to display an image in a picturebox dependant upon a value wich is generated elsewhere in the app, so that if '3' is generated I a picturebox to display image3.gif
if 2 is generated image2.gif. However I have 52 such images to be displayed in 16 picture boxes so I was wondering
if there is a more efficient way than a select case method for each image and each picture box.

View 2 RepliesWorking with System.Cryptography, I'm noticing that data arrays up to a certain size will either conform to the size of the Initialization Vector (IV) or the size of the Key provided. So with a 48-byte Key and a 32-byte IV, up to around 42 bytes of data will encrypt to 32 bytes and 44+ will encrypt to 48 bytes of data. I've tested this with a variety of data arrays, and it seems to always come out the same... but I have a concern that higher byte values in the original array may result in longer encrypted arrays.
how or whether I can construct byte arrays that will be guaranteed to come out of Encryption at a pre-determined size?
I have a need to construct a command Byte to send to another device using bit wise operations.There seem to be plenty of article on how to do this for indiviual bits using an OR'd constant but how do I do this for values that span multiple bits? eg "Bits 4-1" set the repeat count".so how to I inject a repeat count value of say 7 into my command byte?

View 5 Replieswhat is the code to enlarge images as the program is running
ie double click the image and it expands
I have written an application in which, among other things, there is a picture browser, allowing the user to load and look at pictures (jpeg-type). So I thought it would be nice if they could print their nice pictures too. And here is where all my problems started. I've tried almost all the code examples given to me, but none works. Isn't that strange?
I want:
a) The user will click the print button and the print dialogue will appear and thus enable him or her to choose wich printer to use
b) When the choice is made, click OK or PRINT or WHATEVER and the picture/photo will appear on a piece of paper which they can frame and hang on the wall or where ever
Yes I'm sounding sarcastic, and that is because I'm tired from lack of sleep, trying to make this happen. And I only have a few days to complete everything. To make it worse I haven't even started on the part where they are able to print text from textboxes on a form... Oh My God. for some reason I though printing something from an application would be the easy task when it comes to programming in VB. I was obviously wrong. It happens from time to time.
How to retrieve the 10 images from a particular folder in vb.net
View 1 RepliesI'm in the middle of making a program launcher. I've been able to make a version of it before, but now I want to add more options for viewing the shortcuts. The 2 main views I'm trying to get are: Icon only and Icon with the name.
Here is my original code for only the name:
VB.NET
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Start bottom right of screen
Dim working_area As Rectangle = _
SystemInformation.WorkingArea
[Code] .....
I have switched over to a listview because I assume that's what i will need in order to show images. So I guess my first question will be how do I get only the icon from each file and then show it in the listview.
