VS 2008 MyBase.MouseDown Class To Check For Clicks Picture Boxes Not Form?
Dec 5, 2009
Private Sub LMouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles MyBase.MouseDown
If allowMouseCoordinate = False Then Exit Sub
Dim xPos As Integer
Dim yPos As Integer
If e.Button = MouseButtons.Left Then
[Code]...
But this only works if I press on form. But I have a tile based map covering the entire screen.How can I make it so, that It would check if I clicked on a picture box (or simply anything)?

I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.

It all works fine it looks like this:Now thats enough for me but as many other users we have a problem of lack of knowledge when it comes to this:Windows is shutting down, the confirmation box appears and stops the windows from shutting down...This is unnaceptable imho and im trying to find a easy way to detect if windows is shuting down, or in other words if its NOT.So i put a: if windows isnot Shutting down then'all the other code in mybase.closingEnd ifIs such thing doable? all ive found was pages and pages of codes (something to do with api) and some outdated vb6 code...

I was thinking to include a feature in my application in which when Selects a mode from a menu, then we have to go each PictureBox on the form after a certain time. For eg: There are 5 pictureboxes (number not fixed since pictureboxes are created at runtime). When the user selects the mode, the Mouse goes to the center of each pictureBox periodically. The picture box that has focus should have a frame around it with a dark red color as shown in the screenshot clearly (
[URL]. The rest of the functioning is the same as for the application.

how to view and populate a listview with a text file. Now I come seeking wisdom on how do create an effect based upon the location where a mousedown event occured.
Here is my example. (I like to give simple examples because it helps me learn rather than be given the answer and learn nothing).
I am working in vb.net, in a windows form. I have a map of Western Europe called picturebox1.
I want another form to pop up when a user clicks on a section of picturebox1. For example: I want a "Germany" form to pop up when the user clicks on Germany. And such for if France, Spain, Italy, Austria, England, Scotland, etc...based on the location of the mousedown event.
Historically, when working with a picturebox with sections that were rectangle, I would do little screenshots and overlay them over the picturebox and use that as a cheat.
The challenge here is that the countries are polygons and now I need to learn this for real. I am looking for a little direction on where to go to learn about a mousedown event that causes an effect based upon the location of the mousedown event.
This can be a challenge because each country is of different x, y location coordinates so I image I need to create an elaborate if or case statement to capture and evalute. However, I don't know how to acquire the coordinates of a mousedown.

I'm using a series of 3 images within a picture box to create the illusion of a button being depressed when clicked. This is the code I use: Code
And this is the problem I have when doing these events: I am using Image lists, .png format, and I have made sure that they are all the same brightness in photoshop i.e. it is Vb that changes the brightness.

What would be the best way to manage multiple Picture Boxes?I am thinking an array, but if that is so, how would I build this array, and what would be stored in it?

Visual Basic Project - Student Check In Form using an Access database backend This form needs to draw information from an Access database containg tables for STUDENT, INSTRUCTOR, and SECTION. These all need to have primary keys and ids. When (the user) clicks on the drop down box that displays all the sections:
{Table Tennis 1, Table Tennis 2, Table Tennis 3, Billiards 1, Billiards 2, Billiards 3}This should populate the listbox or datagrid from the STUDENT table with the Students that have the same SECTIONID as the SECTION selected in the drop down menu above.
After the Student list has been populated (the user) clicks on a student name in the listbox/datagrid and this inserts that student into the CHECKEDIN table that has a datagrid/listbox associated with it.
This is a great project to practice connecting a database to Visual Studio 2008 .net and playing with the data that has been pulled in. You could use SQL instead of Access.

I'm trying to make a Lottery program on visual basic 2008, but there's one thing that I am stuck with.Note: My explanation may be hard to understand, so if you would rather have me send you my code and see how it works, I'm fine with that. My code is pretty long so far, so I didn't know if i should post it on here.
My program has 6 picture boxes lined up horizontally, and has one text box underneath each one. There is a play and stop button on the bottom left corner.I've altered my program to have animations for the picture boxes. Instead of having a random picture picked, I have it so that each picture box scrolls through a series of 10 numbers when the user presses play.
When the player presses stop, the picture boxes stops scrolling, and random pictures are displayed in each box. (The picture is really just a black circle with a number in it).The text boxes below the picture boxes are for the user to put numbers in. These are the numbers they select for the lottery. Now this is my predicament. Since the picture boxes decides what the winning lotto numbers are, how can I compare the numbers in the text box to the pictures?

On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip

I have VS 2008 and use VB, not C#/C++ or whatever else. I'm trying to make a battleship game, and I've decided to use the only method I can think of to control the grid. A 2D boolean array for position marking. I have the array set up, and the grid set up in the design form, but I can't figure out with all my research how to link them together. I'm writing this program to shake off the rust before school starts again, and for fun. I took VB in school last year, a half year class, so I have a foundation, now I'm self-educating myself above and beyond the class. I've searched for a way to use a picture box array to use the coordinates of the ship to .Visible=True the picture boxes. I've been working on this for 2 days straight with no results. I just need a little nudge in the right direction. The exception I've been getting with my latest concoction of code is NullReferenceException was Unhandled. I think its referring to the fact that I have no idea how to link the picture boxes into the array. Here's my code, and I'll comment where the exception is thrown:
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click

I have 8 check boxes and 4 radio buttons on a child form. When the User checks a Check Box, they then select a radio button. They will do this for 1 to 8 of the check boxes. The only way I could think of to keep track of this is create 8 panels with 4 unique radio buttons in each. Then I would set the visibility to each one accordingly. This method has other logistical errors than just trying to get the design view worked out.
I was wondering if there was a way to just use the radio buttons. I thought I could set a boolean variable to keep track of each Check Box's Radio buttons. Or an integer variable. For instance, if Check Box 1 is checked and Radio Button 1 is checked then myVariable's value is 1 or whatever. Then when I actually run the app, I can check the value of the variable do do what I need. Does this sounds plausible?

I'm trying to pass data from the main form to a business class form for calculation.I have 3 types of cars and I can't get the code right to pass that to the business form. It seems correct to me, but obviously, it's not.This is the code for the calculate button, I can't figure out why its telling me that CarSize is not a member of the business form when I have it in the Enum statement at the top. I'm going by what the book says and this appears right according to it.
Dim CarTypeInteger As Integer
'determine the car size from radio buttons
If LuxuryRadioButton.Checked Then
[code]....
In the book it says to specify the class name when declaring the enum on the business form. So to me it looks like it should be -RentalRate.CarSize.Luxury The error I have is 'CarSize' is not a member of the 'ChristiansCarRentals.RentalRate'.

I need to draw several line-graphics on a form, then select and drag individual graphics to new locations. Is it possible for example to give each graphic path an identity when drawn, then select any one (via mousedown, whatever) and link it to the dragged mouse co-ordinates until released? MS Visio has exactly this ability - can it be done in .NET?

I'm trying to create an animation with 5 picture boxes (labeled picturebox0 - picturebox4) but I have a specific order I want them to display. I made 5 picture boxes, added images to them, and stack them on top of each other.
I want the order to show this: picturebox 0, 1, 4, 3, 2, 4, 2, 3, 1, 3... etc
The code I have using if-else statements which would work if I wanted to repeat the same display pattern but I need to manually right the pattern... I have at timer set to change the pictures every 2.5 seconds.
Code:
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick
System.Threading.Thread.Sleep(1000)

I need an indexed set of picture boxes. The number, n, of these objects is determined at run-time.Migrating from VB6!! I had used the load command n times to create a control array from a "seed" picture box. In code the individual pictureboxes are accessed as formula(k), where formula was the name of the control array and k is an integer. Examples can be seen at url... the chemical formulae, Ni2+ etc., are draggable picture boxes (curve captions if you like), so that they can be placed wherever the user wants.How can I implement something similar in VB.NET?

I want to creat a photo hunt for 6-8th grades summer computer camp. all I want to do is have them change the image in paint, then load the two images in picture boxes on a form. When I create the ovals to identify the differences in the images, they automatically are behind the picturebox.I can't figure out how to get the ovals to be in front of the picture box. I click the picture box and say send to back but the ovals are still behind the picture boxes. There is no right click on the ovals to send to the front. there has to be a simple answer for this. I also tried putting the images on the background but when I make the ovals invisible, they are not clickable and I cant set the border to 0.This was a no brainer in vb6.0
