Forms :: Picturebox Flickering When Location Changed?
Aug 3, 2010
i am making an RPG game with visual basic...The character is a picture box.The problem is when i move the charactor with the arrow keys it flashes black for a milisecond. I think added animated walking where it slowely moves 32 pixels but not it goes black the whole time... what can i do sto stop it going black everytime it moves?
Old movement
If e.KeyCode = Keys.Right Then
player.Image = My.Resources.mainplayerright
moveto = New Point(playerx + 32, playery)
[code]....
That code moves the player slowely but causes a big black line to merge then just ends up teleporting the player..How can i get rid of the black flash during movement?
I am using MDI form and nearly more than 10 child forms.. Here, When i load or unload some forms, it flickers very much.. It is not as much good.. So i need to avoid this.. How to avoid form flickering?
For those who have programs such as Skype, you may already be familiar with this action. Basically Skype and some other programs have a feature where when you move the form near the screen boundaries it jumps and "locks" into position into the corner of the screen. To my understanding, Windows 7 seems to have this feature, but it is not as jumpy as Skype is. It seems you have to be within 20 pixels or so for it to work with Windows whereas Skype seems to work if you are near the corner.How would I go about moving the form near the corner and automatically relocating the form to that corner? For example, if I placed my program near the top left corner, how would I relocate the form to (0, 0)?
I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?
Here's a couple of videos of the problem: [url] [url]
Notice the black screen with the white lines on it or the flash of the desktop after I click "Movies." How do I get rid of that?
i am using an unbound datagridview so i can dynamiclly add rows. all that is working fine. but the grid is not is the location i have coded.. i am using the defualt form as a base then coding the unbound stuff in.. should i just create a blank class file and do everything? the only problem i am having is the grid must bees in the correct location according to the pixel point that i have given it. Right now it is placing the grid at point (0,0) no matter what point is entered on the line for location. so what am i missing??????
I have a number of textboxes and labels in a panel which has to scroll in order to view them all. The user is then able to scroll down and click on one of the labels which has a textbox that appears so the user can change the corresponding value in the label. For some reason, if the user has to scroll down at all to any of the labels that are initially out of view, when they click on the label the textbox appears far below as if it was at its initial position and not directly where the label currently is.
I am trying to check if an image has been changed from a picturebox in a if statement. If I cant check if a image has been changed then can I check if a picturebox been clicked.
I am currently working on a game that I want to add squirrels running around at random for me to kick off the form. Ex.. picturebox.location=200,200 And I set a new location for it, as 5,5, how can iIget the picturebox to move to that coordinate, a few pixels at a time until it gets there, so it looks like my squirrel is running to that location?
Can the background image in a picture box be moved, or located some where else, not the top left corner?I am aware of the layout that can be changed but that is not what I am after.
Im in need of somehow a code that with a picturebox, depending on WHERE you click it will do something. Lets say theres a picture of a face. The eyes are at like x = 12, y = 28 , if the user clicks the picturebox around that area a msgbox will come up saying "Eye" or something, this is just an example

I have a picturebox (pbRows) that I want to always be aligned with the right side of the screen. The form may be wider than this (I have a horizontal scrollbar), but the picturebox always needs to be along the right edge of the screen. Currently I have this code snippet in the form_load subroutine:
Dim rowsX As New Integer rowsX = Screen.PrimaryScreen.Bounds.Width - pbRows.Width pbRows.Location = New Point(rowsX, 25) However, the picturebox is aligned with the right edge of the form (initially hidden off the screen). Am I missing something obvious?
Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove ListBox1.Items.Add(e.Location.X.ToString) ListBox2.Items.Add(e.Location.Y.ToString) End Sub
I am a grade 11 student in high school and am struggling with a project in my computer programing class. in the project we are to create a mario game, where you have 2 pictureboxes (the player and the enemy) one picturebox, the player, is moved using the keypad, the goomba isn't moved at all. the object of the game is to 'kill' as many goombas as quick as possible. I need to make the game so that if the boundries of the player intersect witht he boundries of the goomba, the goomba will move to a random location.
I can't get the goomba to move to a random location, here is my code. I highlited and bolded the part of the code that I am having the prolem with.
Public Class FrmQ4 Dim intLocation As Integer Dim intCounter As Integer
I need to know how to get the position of the mouse within a picturebox just as you would with e.location, but you can't use e.location with a picturebox and you also can't use Picturebox.Mouseposition which is very unfortunate.
I created a game where you use the mouse to play, it's like the game labirynth. You can't touch the walls or you lose. When I start the level I want the cursor to appear in it's starting position, which is a red picturebox.
Here is the code I used: Windows.Forms.Cursor.Position = New Point(679, 650) The location where the cursor appears is actually dependent of the resolution of the screen.
For example: with my monitor resolution, the location (679, 650) is right on top of the picturebox i need it to appear on. but if you have a different resolution on your monitor it will appear on a different place. I need to actually make it appear on top of the picturebox.
I'm inexperienced with windows forms (vb.net), and I have a rather silly question.I'm opening an old project of someone elses, and there's a PictureBox control on the form. The PictureBox has a photo, and I'm trying to find the location of the photo on the computer but can't find it.In ASPX, I can just look at the code behind and find out where the tags are pointing to (for the photo).The only code that exists for my object, with the image property is this: [code]
I'm new on VB.Net.When I move my Form,it changes my picture location automatically so i can not Get pixel value correctly and it gives me Error.[code]...
i have a chart of images.. and i want to load individual images into picturebox from that chart..chart = big image, eg alphabet chart. (yes i am creating a game for my small nephew.. pictures and alphabet) now, i want to show different pieces of images into picture box. like the A box, b Box etc one option is to cut the chart into pieces, save each piece with different filename and load individual filename into picturebox.but i saw somewhere that we can use pixel location to load images into picturebox..as i recall it required two pixel location, 1 was upper left and other was lower right.. and passing that pixel locations would load the rectangular image between those pixel locations into picturebox?
In my VB.NET application when I try to get the image location using picturebox.ImageLocation (path), it is returning null. I have to use that path string in filestream's parameter to open it. Since it is returning null, I couldn't open the file (image) in filestream. The following error is coming: "Path cannot be null"
This is my code: Dim path As String = Picturebox1.ImageLocation Dim filestrm As FileStream = New FileStream(path, FileMode.Open) Dim arry(filestrm.Length - 1) As Byte filestrm.Read(arry, 0, filestrm.Length)
i need a picturebox to, when an event has happened to either revert back to its original place.or set a location for it to go after the event has taken place.ive tried lots of different code but its not working?
I'm basically putting some validation logic around an undo button on my form and i'd like to check whether any fields on the form have had their values changed so i can ask the question "abandon changes?". This seems like something pretty standard to me but I can not see how to check whether a value has had its contents changed (without recording a before value and comparing it to the after value which for large forms would be quite horrendous to code).
In the language i used to use we used to walk the object tree (so we dont have to specify each object individually like text box, combo box etc) and check any object that have value-changed = yes to indicate the validation was required.
I'm trying to build a project where I have a set of products in a listbox. When you select an item in the listbox, a picturebox shows the preview of that certain product.I practically finished the entire project as well as the picture part; however, I realized that the way I set up the coding, I used image locations from my hard drive meaning that someone can't view them on another computer.This is a portion of my coding:
[highlight="Dim PicSelection As String PicSelection = ListBox1.SelectedItem Select Case PicSelection[code].....
I have a project in vb.net (2008) .net 3.5 in which I have a mainform (Not a MdiParent) and I created another form I want to use as a tip form. I'm trying to set the tip forms location to the lower right of the mainform no matter what the size of the mainform's height and width.
I tried this : TipForm.Location = New Point(Me.Width - TipForm.Width, Me.Height - Me.RibbonControl.Height - Me.statusbar.Height * 1.5 - TipForm.Height)
I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?
on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?
I am developing a windows app in VS2008 to be used along side ESRI�s ArcMap. Most ArcMap users will have dual monitors and I would like the user to be able to choose which monitor my app is loaded on to.
When I deploy the app using the standard install package, the app will load onto which ever monitor the user places the desktop shortcut. However, when using the ClickOnce method of deployment, the placement of the shortcut does not matter and the app always loads on the primary display monitor.
Is there a way to control where an app is loaded by code or any other method?
