Interface And Graphics :: XNA Graphic With A Graphic?
Jan 14, 2010I'm trying to make a mini map for a 2d space shooter of mine; I've for the math down (I think) for when an item should appear on the mini map, but the problem is the graphic. As it stands, the graphic spills over the edge of the mini map graphic and disappears only when it's fully outside. I need it to crop the image, or at least not show it off the mini map graphic.I thought of using the sourcerect rectangle of the spritebatch.draw, but it seems to me that would only work for the right and bottom section, as I can adjust the size of the rectangle. I haven't tried this yet, but I will soon. Can the location of the source rectangle be changed in relation to the graphic that it is a part of being drawn so that I can use that to crop the left and top sides?

Picture Box Transparency Layers?
Aug 15, 2011i 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!
3 Layers Treeview Nodes Checkboxes?
Sep 5, 2011I 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

Adding Security Layers To Database
Aug 12, 2011I 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.

Sep 11, 2009I 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 RepliesGet Multiple Image Layers On Visual Studio .net (Basic)?
Feb 20, 2010Back 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.
VS 2010 Display And Hide Object-group In Separate Layers?
Feb 7, 2011I 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 RepliesVS 2008 Multi-threding - Adding Multi-threading Facilities - Cross-thread Operation Not Valid
Feb 10, 2010I'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

Apr 13, 2010We have a great book written for Visual Basic 2005 that we type code that is prepared in advance. We are using Visual Basic Express 2008 and normally this works really great; type the code run the program and it works, however I am running into a snag.

is there a difference between VB 2005 and VB 2008 that would be causing the errors? or am I missing something subtle maybe mistyped?

Creating A Graphic Barrier?
Feb 17, 2011I am working with a graphics program in VB to move an image around the Form. I'm trying to create barriers that cannot be crossed. At first, I tried to represent this with a 2D array, but this proved too complicated. For now, I'm trying to create a series of rectangles. What I want to happen is when the point the image is anchored at intercepts one of these rectangles, it will either be prevented from moving or sent back to where it was directly before the image moved. I know there is an intercept command, but I've been unable to figure out how to use it in this content. The code I have is below.
Public Class Form1
Dim PlayerSprite As Image
Dim BGImage As Image
[code]....
As I said, this is to create a graphic barrier. However, I expect to make a number of these Rectangles?

Make Graphic Persistent In VB And GDI+?
Sep 24, 2010I have a converted VB6 App that would draw irregular shapes on a PictureBox when I click on a button, and these irregular shapes would persist until I either close the App or erased the PictureBox to start the display anew.I converted my App to VB.Net to do the same, i.e. draw on a PictureBox again, but the drawn lines appear briefly and then, at the end of the drawing process, when my App returns control to the Operating System in wait for another event, the graphics disappear as if erased by the App (which I don't do of course).I have created a Graphics Object associated to my Picture Box as:
Dim CurrGraphics as System.Drawing.Graphics
CurrGraphics = PictureOut.CreateGraphics
I then use the DrawPolygon and DrawLine methods to add the irregular shapes I want:
CurrGraphics.DrawPolygon(CurrPen, Pts)
CurrGraphics.DrawLine(CurrPen, Pts(I).X, Pts(I).Y, Pts(I+1).X, Pts(I+1).Y)
where CurrPen is a defined Pen, and Pts is the Points() array with the coordinates of the displayed shape. Several dozens irregular shapes are drawn and then the subroutine stops, and returns to waiting for another request from the user.What could be the prime reason why graphics do not persist in a PictureBox, and are erased immediately after they are created ?
PS: I do not use the PainEvent of the PictureBox PictureOut, as in the example given in the VB documentation (below), as the display process is initiated by clicking on a button, and I cannot relate how to transfer control to the PaintEvent as below:
Private Sub Form1_Paint(sender As Object, pe As PaintEventArgs) Handles _
MyBase.Paint
' Declares the Graphics object and sets it to the Graphics object
