VS 2010 Express - PictureBox Design Properties Box Shows Properties That Cannot Be Accessed?
Mar 5, 2012In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?
Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?
Jun 28, 2010I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

IDE :: VB Controls Properties Not Visible?
Jun 6, 2011I recently uninstalled an IDE for a motion control system (Delta Tau) that is a visual studio based product. Now when I bring up my Visual Basic 2008 IDE that I'm using to write an HMI for the control system, the properties for controls placed on forms doesn't appear in the properties window. And if I click on properties for a form I get the FileProperties2 information, not the form control properties such as size, location, or color. I am also not able to access the controls in the VB toolbox to place on a form. The controls are grayed out and unavailable. what part of Visual Studio 2008 got broke in the Delta Tau uninstall?

View 1 RepliesMake PictureBox Visible In Program?
Jun 25, 2009I have written a VB2008 program in which I want to put graphics output in a PictureBox but keep the PictureBox hidden until a "Show Graphics" button is pressed at runtime. I have done this by setting the PictureBox's Visble property to False at design time and then adding a line in the Button Click code (before the main graphics code) to make .visible = true. Now when I press the button, the picture box becomes visible but stays blank. I have to press the Button a second time to get the graphics to show. It doesn't matter where in the Button code I place the PictureBox1.visible = true line, the result is the sdame. WHY ? Other VB Controls, eg RichTextBox will stand being made visible and then display output with only one click of the button, why is PictureBox different ?

Visible Surface Of Picturebox Is Too Small?
Jun 27, 2009I'm drawing lines directly on a PictureBox. My problem is that the visible surface of the PictureBox is smaller than expected, considering the Height and a Width properties.For example, there is a PictureBox with Height = 200 and Width = 400 points.When I draw a point with coordinates of (0,0) it is clearly visible in the topleft corner. But when I draw a point with coordinates of (399,199), it's not visible. Actually, the bottommost and rightmost point in the Picturebox seems to have the coordinates of (397,197).
What's the reason behind this? Is the PictureBox always two points smaller, or is it size-dependent? Or a wrong setting?

View 1 RepliesForms :: Random Functions - When Start Program And Click Picturebox - Same Card Will Always Come Visible
Mar 30, 2011Okay, so I'm doing a card game and I'm trying to set that when picturebox (PictureBox1) is clicked, a random card from 13 cards will come visible. Problem is, that when i start the program and click the picturebox, the same card will always come visible. As you can see i've put a button (Button1) which will hide every card. If I press Button2, then Button1 and then the PictureBox1 it will show differend card, but the cards which come visible are always the same.
e.g i press PictureBox1 (which will make card visible), then Button1 (which will make PictureBox1 non-enabled) and then Button2 (which will hide every card and make PictureBox1 pressable). Lets say i pressed the PictureBox1 four times and i got cards: 9, 6, 7, 3, then I close the program, start it again and press PictureBox1 again 4 times and it will show the same cards (9, 6, 7, 3). How can this be done that it will not show the same cards always?
Here's my code...

VS 2010 New PictureBox Located Relative To Another PictureBox
Jan 21, 2011I am working on a small desktop form in VB 2010 and am trying to place a pictureBox with an image in it, next to another pictureBox already located on the form when the user clicks a button.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim tool As String

But for some reason the newPictureBox with image from "ptext" does not show up on the form. When I specify the new Point to be something like, (50,50) instead of getting the first pictureBox coordinates, the new pictureBox shows up in the right place.
Am I using System.Drawing.Point wrong? Or is there some other error that I'm making?

Jumping Between Forms - Making A Form Visible And Not Visible
Jul 17, 2009I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

View 8 RepliesVS 2010 - Public Variables, Functions Are Not Visible In Form2
Jun 26, 2011I've got a program that runs from one Windows form, Form1, with stuff declared all in that class: public variables, public functions, subs, etc. I decided that the form was getting cluttered, so I added one button to bring up a new form, Form2, and I put some of the buttons & check boxes for testing over there, so that Form1 can be more visually clean. Problem: when I go to put the code for the tests into the buttons on Form2, none of the public variables or subs or functions that reside in Form1 are visible in Form2. What statement/s do I need to add (and where) so that the public "stuff" that's declared in the class for Form1 is visible within Form2, please?
View 6 RepliesVS 2010 DataGridView - GetRowDisplayRectangle Only Works When Form Is Visible
Oct 20, 2010I am running a website for a F1 racing game, where users can submit their laptimes and compete with each other for the fastest time.
I am now trying to have my website create an image of the top-5 users every... 5 minutes or something, and copy it to the webserver somewhere I can link to. This way the image under that link will update with the latest information every 5 minutes.
To layout the times (these also include the position (1 to 5), the username, the platform, the time of course, and some more details) I am using a DataGridView. I could take the long route and layout the specific 'columns' manually, but I thought using a grid was far easier. I simply set some properties of the grid to make it look nothing like a grid (basically hide the column and row headers and grid lines and give everything the same backcolor). Then I load the times into the grid, and take an image of it using the Control.DrawToBitmap method.
This works fine, but it returns the entire grid. This is a problem because I made the grid extremely large (5000x5000) so that it can always accommodate the times regardless of the length of the usernames. So, the image I get is 5000 pixels wide while it only contains data in the first 500 px orso.
I am currently using the GetRowDisplayRectangle and GetColumnDisplayRectangle methods to figure out the part of the grid that actually displays the times, and use that to cut the image down to the portion I need.
But here's a problem: these methods only return something when the grid is on a form that is currently being shown! I am already giving the grid a parent form (even though I am just creating it in memory and it doesn't need to be displayed anywhere) because otherwise the data wouldn't load, but I was never showing that form. Now it turns out I do need to show the form, very briefly, in order to figure out the area that I need to take a snapshot from.
Remember that this is all happening on a webserver, so I'm not absolutely sure if this is a problem. Is it ok for a webserver to have a form popping up and down every 5 minutes? Or will this cause problems? I honestly don't know but I don't think it's a good thing. Moreover, it also pops up on my own machine when I'm testing, and it's damn annoying.
So my question is basically twofold:
1. Maybe I should ask this in the ASP.NET forum, but is it a problem to show a form briefly every 5 minutes?
2. Is there any other way to get these Get...DisplayRectangle methods to work without having the grid on a physically visible form?
