I am using a Gif animation on my Mainform. When i open a second form and then return to the mainform - the animation stops. How can i make sure that the animation restarts after the second form was closed?
View 1 RepliesI've been trying to make basically a simple animation player inside a class so that I can use it in a game I have to make for a school IPT project. When I first tested out some code I found, it was not in "class form", ie there were just loose variables as I was only animating a single .gif file. The code worked perfectly, and the animation was drawn frame by frame by the e.Graphics.DrawImage function.
Now that I have moved the code into a class (So I can run more than one animation at a time, though Im still trying to get only one to work), The e.Graphics.DrawImage function didnt work. It would draw the first image, but then (even though the function is called as shown by stepping through the lines of code), the picture doesn't update. I know the frame has changed as Ive kept track of the current frame in the debug window, but it still wont work.
I have had troubles like this with other GDI functions, where if the variable to draw is inside a class (etc) it simply wont work, it will only work if it is a loosely floating variable. (i.e. Sprite.Image doesnt work, If I just make an image it does). With the code below, I have tried in the e.Graphics.DrawImage function submitting me.wth.animatedImage and wth.animatedImage
Public Class Form1
Dim wth As New vsprite
Public Class vsprite
Public animatedImage As New Bitmap("C:Documents and SettingsSamDesktopexplosion.gif")
Public currentlyAnimating As Boolean = False

View 2 RepliesI'm a new to visual basic and I need to create a boat animation in vb in visual studio 2008. The animation needs to be able to move from left to right, then stop in a specific place and then move from bottom to top. However before it moves it should bring up a labels. I have managed to move the boat from right to left using the timer and left and top assets but unable to stop it on a particular place on the form.

View 3 RepliesI have a form that contains a crystal report viewer. When I open this form, it runs a report. I am using a .LDB viewer to tell who is logged into an access database. I noticed that when this form opens, the computer logs into the database and stays logged in. Even when the form is closed, the computer is listed as "logged in". If I run the report again, it just adds another instance of that same computer logged in. Therefore, it continues to pile up logins until the application is closed.

View 9 RepliesI'm making this rubik's cube program, and I wanted to make a 3d animation of the cube doing the moves, and I figured the best option for that was using the XNA extension. However, doing that brings up a problem. I want to have lots of different options in the Mdi parent form that will interact with the moving 3d cube. The problem with this and using XNA is I can't use both the normal form and the XNA game in the same project. How would I go about having the 2 different projects interact? Just like a txt file or something?

What will happen to the datareader when the Connection is closed ( Conn.close)
Will the Cursor that is used by the datareader be freed ? or will it stay open ?
If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?
Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?
I am making the interface controls on my forms to go from right to left using with RightToLeftLayout and RightToLeft which I have set the properties set to true.

View 3 RepliesI need a way to detect when a child form has been closed. I've created an MdiWindowList thing (but in the form of a toolbar with buttons, similarly to the Windows taskbar), and everything works great, but the method I have for refreshing the taskbar's windows has to be called when a child form closes. I've trying calling the method from the child's Form_Closing event, but there's a slight lag so whenever there's more than 1 window open the first one gets skipped (then the others close properly, since the taskbar is being refreshed first before the form actually closes).

Works fine the first time but after closing the form opened by the DC, if I try to open it again, throws an exception "Cannot access a disposed object".
Since I can still access any other form not previously showed I guess that the closing changes a status that allowed the form to be .Show, there is no F.Load , F.Activate after the exception doesn't seem to do anything. What should I do?

View 3 RepliesI want to make an application witch involves logging into google. It is basically a small application to always have your gmail with you without always having to go to the web browser and log in. Basically what I want to do is, when the person signs into their google account (or the page url changes) I want the webbrowser to refresh and go to a new point in the form and create an animation using a timer. I dont need advise with the animation, I just need to know how to link it together with the person signing into google. And also, If it's possible I would like to have the person log in without the actual google web interface, but with 2 textboxes and a button. I am using Visual Studio 2008.
