I am trying to do a game application similar to chess, where i need to move the game peaces(graphics) over another graphics which is the game board. using the mouse. How can I do multiple layers of graphics and control their movement(without direct x)?

i got a large picture box sent to the back with a default image.i got a few picture boxes set to transparent and they are placed in front of that large picture box. these picture boxes have no images, just set to transparent in the properties.
I use the mousehover event on those picture boxes so when one is hovered over, it will change the image of the large picture box which is behind it.the problem is that even though those picture boxes in front have been set to transparent, when the large picture box behind them loaps a new image due to an event, it doesnt show through those picture boxes which are in front of it!
I have a 3 layer treeview and is using the code below. I am getting it to do the following,
1) If parent is checked, check all child nodes.
2 If just one child node is unchecked, uncheck parent node.
3) If all child nodes are checked, check parent node.
Code below only works for 2 layers. Would appreciate if you can guide me how to make it three. There are much information on treeview but most of them seems irrelevant =/ Will be great if you can show me a good guide on treeview control.
Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As TreeViewEventArgs) Handles TreeView1.AfterCheck
RemoveHandler TreeView1.AfterCheck, AddressOf TreeView1_AfterCheck
For Each node As TreeNode In e.Node.Nodes
node.Checked = e.Node.Checked

I am developing a simple database with typed datasets. My employer wants to put two security layers in my database for a verifier and administrator. Anyone can change the database. But later it will be rechecked and marked as verified! and once every record has been verified, the administrator will append those verified records to the actual database. Can any bro devise me a proper method to do that? Right now what i have in my mind is that i put a verified and authenticate boolean in my database. For each edded/edited record, i mark/unmark that verified/authenticated entity as being set or unset. This approach is easy to implement and gives an option to undo any record changes but i'am afraid will compromise the database in space and time.

2. How to draw graphic with multi-layers, so that we can do modification on peaks instead of coordinate.
I was wondering if there is any way to manipulate layers of a psd from within a VB program. I would Ideally like to inserts just the psd file in and then once a command is clicked turn one of the layers on or off.
I know I can accomplish this inserting a jpg/gif for each layer and have that image be turned on or off by a button click, but I figured using the psd would save room and if something needs to be aligned differently I can just make a change in photoshop. Opposed to trying to realign the coordinates in VB

View 6 RepliesBack in Visual Basic 6.0 and prior I could have a picturebox control and then have multiple images on that and using a gif file; then I'd have some images transparent. For example, I am trying to make a map where each country has it's own layer and the void is transparent so the underlying picturebox contains all the water.
However, in visual studio I've noticed the image control is now gone. I tried using a panel and a picturebox on top of that and it works but I can't use another picturebox on top of that picturebox, nor can I stack multiple panels with the same affect.
I want to create a game using visual basic 2010. I'm a specialist in VBA and Excel but not VB 2010.I want to display and hide a whole group of objects. In Acces I used for such cases the TabControl. For example in Tab1 the Game, in Tab2 the highscore and in Tab3 the options. Then I made it transparent, so that the Tabs (Buttons) are not visible, only the objects in Tab1 Tab2 and Tab3. With VBA I select the Tabs controlled by my own buttons (jpg). I tried the same in VB 2010. Without success.What can I do to switch between game, highscore and options without using popups. I want to display them at the same positions. So game objects and option objects should hide and highscore objects should be shown. And the other way round. Like the handling is with different layers in photoshop!
View 2 RepliesWe have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.
The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.
So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...
Im working on a project that needs to print a report of one client.Everything went smooth untill i came across my multiline input text data.When i display it in the PrintPagePreview the text go's outside my page. Even when im printing it only the halve of my text is displayed. I googled and looked everywhere but i can't get a clear fix for it.

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

ok, i know the code is a little rough, but it should be good to give you an idea of what im trying to do, if not i will still explain.simply draw 2 lines one from left to right, another from top to bottom, intersecting through the tip of the mouse.ok, theres no problem there the lines draw perfectally the way i want them.... BUT! now heres the issue im having.i cant get rid the previous lines.i did a bit of good old "Google'ing" and ran across a few links that all pointed me to the ReDrawWindow API, so i tried (as you can see in the above code) but i just cant seem to get it worked out.
So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
Ok I have this: This makes a sub called 'graphicspaint' then writes "demo version" to a picturebox1

View 15 RepliesMy application is all centered around one form with lots of graphics drawings on it.All these drawings take place from within a paint event handler. However, the amount of code within that sub is becomming unwieldy.I have been trying to move sonme of it to another class and use the "dim temp as Graphics = e.graphics" construction to continue to draw graphics. However, I get all kind of argument exception runtime arreors when doing so (and I do not get these with the same graphics operations directly from the original paint event handler. I have also tried to pass on the original e argument, but with the same result.Is my conclusion that there is no solution to this so to continue with the unwieldy amount of code,correct, or am I mistaken somewhere. the "dim temp as graphics = e graphics" is recommended.

View 10 RepliesIn a Previous Thread, I asked some questions about how to create graphics. Everything was OK, until I realized that the graphics are really slow. While I was trying to find out what the problem was, I realized that the processor load was about 50% and my graphics card was not used at all. So doesn't Visual Basic use the Graphics Accelerator to process graphics? What I made is not a real program. It's like an experiment (I tried to make an image flip). Here is the Code:

First part of a huge block will contain some text. That block is not always visible. it will be visible when the user is inputing a control. It is drawn in a bitmap image which will later be a part of the final image of the form.The second part consist of several small bitmap images most probably will contain a letter. These images will not change but there position will keep changing by time. These images will be free to move even beneath the huge block (If visible).I used a timer with 1 sec. interval to redraw form, but when the block is visible it keeps flickering because the timer clear the form and redraw the block.
I tried to use different container for the block like the PictureBox but when the small image goes beneath the block it just disappear.The block color code is "Color.FromArgb(100, Color.Black)" I tried lower Alpha components and that didn't make any difference.My explanation is that the background of the picturebox is not transparent. If I'm right how to make the picture box transparent?

View 7 RepliesRunning VB/Studio? 2010 on XP. I draw on full screen resolution of 1920 wide x 1080 hi.I have set FormBorderStyle to NONE & WindowState to Maximize which seems to be the only way to get rid of the task bar.but w or wout this setting, My graphics draws a full screen twice - mostly repeatably.When I have [code] parameters set to use 9/16th of screen horizontally, the pattern is drawn once the first time I run it and usually once if I hit F5 quickly enough after hitting Alt-F4. But if I wait long enough [a second or 2] after 'Ready' appears at teh lower left of the IDE screen, then it draws the pattern 3 times.for wider patterns, 10/16th, 11/16 up to 16/16, which is 1920 pixels wide, it usually draws the pattern once after I make this parameter change and twice from there on. The 'twice' is repeatable; it 'doing it once' the first time is not a sure thing.
There are more peculiaraities than this, but if we can find causes for what I"ve given you, it might get them all wout making it seem more complicated than it is.I don't think it's in my code; it works - it draws the right thing the right number of times w no compiler errors. But here is the guts of it:
