code that creates a program where a user can key in 3 coordinate points and when the click "Generate Triangle" button. the program automatically creates the program.
View 5 RepliesI'm sure some of you know the equation to get the distance of 2 points on a coordinate grid, and I'm making a program to do just that, the only problem is that when I use the square root function it doesn't return an exact number, what's wrong with my code?[code]...
View 5 Repliesi am having a problem in building up a VBcode for getting the minimum distance between a set of coordinate points. what actually i an trying is to find the minimum distance between one set of coordinate points(A(x1,y1),Bx2,y2),C(x3,y3),D(x4,y4),E(x5,y5)) with respect to another set of CO-ord points (i(x1,y1),j(x2,y2),k(x3,y3),l(x4,y4),m(x5,y5))..

the above is code which i have created till now and the next step is calculating the mindistance criteria..search criteria . rear points is the one we get frm solidworks and b.rearpoints is the one present in database we compare both of them find the one which is very similar to the one in database..
I would like to get 3 point coordinates on mouse clicks and get them display in the text boxes. I'm working with my project. An image will be loaded in a picture box and the image has 3 reference point. I need all the points coordinate to be display separately whenever user click on the points. When user click on the first point, the coordinate of the point will be display as point a, click on the second point,the coordinate will be display as point b, and click on the third point,the coordinate will be display as point c.

View 2 RepliesI have a Car object that does a few things, but I need the program to create New Cars without having to write the code for every new one. Basically, the user checks some combination of Checkboxes and then pushes a button. And I need the program to create a New Car with a unique name for each combination of checked Checkboxes when the button is pushed.
For example, if Checkboxes 1,3,5 were all checked, it would create a New Car that had a different name than the New Car that is created when Checkboxes 1,2,3 are checked.
But I also need the program to be able to check when a New Car has already been assigned to some combination of checkboxes, so that it doesn't create a New Car every time that Checkbox 1,2,3 are checked and instead will use the Car that was already created.

View 7 RepliesI've create a VB2008 app that upon clicking the applications Start button it creates an icon in the taskbar that is visible to the user upon creation, it also shows a balloon tip at the time of creation. This all works great when the program starts but once the balloon tip timeout value has elaped, the icon, in Windows 7, disappears from the visible portion of the taskbar and becomes hidden, which is only visible if the user shows the hidden icons.
My question is this...... In the VB2008 program is there any way to set the behavior of the icon so that it remains visible on the taskbar instead of allowing the icon to become hidden?
The original design of the program was to get an environmental variable, display the value of that variable in the balloontip, hide the form and then check every 10 minutes for a change in that environmental variable. Once the form was hidden the user could see that the program was running by the presence of the icon in the taskbar and if they hovered over the icon it would display the current value of the external variable. Also if the user wanted to return the form to it's full size all they had to do was click on the taskbar icon. With Windows 7 if I hide the form and the icon is not visible in the taskbar because it too is also hiddem this may create a problem for the user as they may not even be aware that Windows 7 hides the icon. So....Is there anyway to insure that the icon remains in the Windows 7 taskbar or is this a case where I need to re-evaluate my program design?
In my project, I want to use Coordinates of a place (eg; London) which is selected from a list of several thousands of coordinates of places.
I thought of using comboBox / ListBox to display the list of the coordinates of places.
I want to know how to make this "editable"; ie: anyone using this program should be able to Edit / Add / Delete a coordinates of a place. And the newly added Place should be saved so that he/she can use it whenever it is needed.
Basically what I want to do is create a program that every now and then (maybe 10 minutes) switches between either, all the windows currently open, or a selection of all the windows currently open, then checks the colour of a location on the screen. At the moment I have the program checking the colour at a specific coordinate, so that's all good. The problem I have now is how to switch between windows.
I've thought up a few ways to do this. The windows that I care about checking all have the same name, the same process class, but different process IDs. I already managed to stick all the process IDs into an array of integers hoping that I could use them but I don't have a clue how to bring a window to front using just the process ID. So the first method would work if I could figure out a way to do that.
My second idea, which is a pretty rubbish way of doing it, would be to simply simulate pressing Alt+Tab however many times to change between windows.

I sent the application exe to a user to test and they get an unhandled exception error and the details show my personal My Documents Folder/DEBUG path from the project. So I tried to use Application.ExecutablePath but when I release that it points to "My Documents" Folder (not the debug) folder. The file to open is in the same folder as the exe is in but for some reason the error occurs because the application is not looking for the file using the path where the EXE was launched from.

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
