What is your select query that is tied into the select command?

This is command: "SELECT * FROM tasks"
Have you got some examples that show how to wrok with MySQL??

I think you might be missing a ; at the end inside the quotes. This may be silly to ask, but is there data in the table

I have just started with VB.Net, and so far I am having a blast - however I have hit a wall with regards to the QuickTime component offered by Apple. I am posting this message here to see if anyone here has or is using it.
In the below URL (listing 3) you can see an almost perfect example of how to convert a file in VB 6 using QuickTime. I am only stuck on two issues: where / what is control.movie coming from (it's supposed to be the file you want to convert but I dont see where it is created or being passed from) and I need to get QuickTime to report back with it's export options, or the codecs which can be used to export.
http://developer.apple.com/technotes/tn2006/tn2120.html
This is technically my third program I have written so far, the second one being a total rewrite of the first. I am pretty sure the answer is right there staring me in the face, I just dont have the experiance yet to see it!
Any help at all would be greatly appreciated.
Thanks,
Mark

I need to start a console application on a remote machine and have its console windows visible in on a user's desktop. So far I know of a couple different ways to start the console app, but not so that its visible to a user.
Any ideas?

This is a HUGE security violation. You cannot launch interactive processes using any methods exposed by the .NET Framework or WMI. You MUST use a third party utilty to launch the app, like PSEXEC. Google for it.

Thanks for the reply. I must admit it came much quicker than I expected.
I am aware of psexec but was hopeing that I could avoid using it. If no one else has any thoughts, I'll have to look elsewhere.
Thanks.

To launch an interactive process, you simply have no alternative. None of the methods provided in the Win32 SDK, WMI, or managed code will launch a process interactively. The user logged onto the target machine will never see it. The reasons for this are self-evident.

Hello every one
I am phasing some issues while i am tring to save a image..
My application works as follows
It is a application in which i am using a tablet to to let the user write free hand
I am able to do the first part by creating a bitmap and graphic object. I am capturing points and drawing lines between them
My next objective is to load a existing image and let the user draw over it and save it...
I am able to do it but when i save it back it gives a GDI error as “A generic error occurred in GDI+.”
I also have a option to let the user clear the old image and create a new one. When i do it i am able to save
The codes are as follows
form load
'Lode a existing image
picDraw.Image = System.Drawing.Image.FromFile(im_path)
'Associating the graphics object to Picture box
bm = New Bitmap(picDraw.Width, picDraw.Height)
g = Graphics.FromImage(bm)
'Draw on the Graphics object.
g.FillRectangle(New SolidBrush(Color.White), _
0, 0, picDraw.Width, picDraw.Height)
'Load the prescription to be edited
g.DrawImage(picDraw.Image, 0, 0)
Clear the image
' Draw on the Graphics object.
g.FillRectangle(New SolidBrush(Color.White), _
0, 0, picDraw.Width, picDraw.Height)
picDraw.Image = Nothing
Save the image
'Update the picture box with the latest bitmap
bm = picDraw.Image
'Save the bitmap as Image on the stated path
bm.Save(path_string, System.Drawing.Imaging.ImageFormat.Gif)
There is a timer which executes after every 50 milliseconds, hear i load the bitmap's contents in the picture box
picDraw.Image = bm
Can any one plz hep me out

Hi,
some comments that may or may not help you:
1.
"A generic error occurred in GDI+.” is the general message you get when something goes
wrong inside GDI+, the graphics subsystem. If it occurs while trying to save, it
may mean disk full, bad file name, ... or fill locked.
2.
Image.FromFile() keeps the file locked as long as the Image object lives.
Image.FromStream() does not do that.
3.
Taken together, if you try to save to the same filename you used to load an image from,
and that image is still alive, then you should go for FromStream().

Thanks a lot...
after posting this query did some more research i am able to find that when i want to over right the old file i am not able to do it...
is it another way to handle it...
I think there is a crude way but i am not satisfied with it...
The crude way i think should work is that copy the file to be loaded on as a temporary file at a different location and over right the original file
now with ur input i think the things should work

frmnew is set the very first form to open when the application run.
both forms contains a menu bars having two buttons on them.
one button for exit the application and the other button allows the other form to open(.show).

Me.Close()<br />
Me.Dispose()<br />
Application.DoEvents()<br />
frmupdatemodified.Show()
the last line frmupdatemodified.Show() shows the error cannot-access-a-disposed-object.
what is going wrong please tell to solve the problem.

frmupdatemodified has already been closed and disposed. When you dispose of it, set it to nothing, and then you can check if you need to reinitialise it.

You have only tried part of Christian's suggestion... you need to re-instantiate the form if you need to re-use it. At the .Show(), the object fromupdatemodified doesn't exist.
Another point - the Me in the above sample... is it the form where you created the frmupdatemodified form object? In that case, since you have already called Me.Dispose, any objects created will also cease to exist.
