If I use the code LongHC provided, it dosn't work at runtime. Then if I try to make NotifyIcon.Icon the icon that LongHc's code created I get the same error except in a messagebox in the designer.

Argument 'picture' must be a picture that can be used as a Icon.

OK

Yeah, I get an ArgumentException, "Argument 'picture' must be a picture that can be used as a Icon."

Sph, forget CodeProject, I did it myself.
WebRequest requestIcon = WebRequest.Create("http://www.met-office.gov.uk/images/w1x15.gif");
WebResponse responseIcon = requestIcon.GetResponse();
Image image = Image.FromStream(responseIcon.GetResponseStream());
responseIcon.Close();
Bitmap b = new Bitmap(image, 16, 16);
notifyIcon1.Icon = Icon.FromHandle(b.GetHicon());

How can I add a type Image or any picture/image to a ListView at runtime without using an ImageList.
For example, I have an image type Image, I just want to add it to a row in my ListView.
So far the only way I've been able to do this is by first making a SmallImageList and putting my Image in it, then associating that ImageList with my ListBox, and then setting the ImageIndex to 0 for my Image.
That's alot of work. Can I simply just add an image?

No, you can't. Even each item in a ListView can have it's own ImageList.
But in no case can you just "add an Image" and move on.

I have a form that I have show up when a lengthy process (doing a search through files) is ongoing basically as a status window. The trouble is that controls don't paint properly.
Below is a link to a picture of what it kind of looks like (the left side of the form didn't capture well for some reason although it actually correctly displays):
Here[^]
How can I resolve this?

Without knowing anything about how your searching for files, your threading setup, form and code details, ... There's nothing we can do to help.
All we know is, your searching for files and trying to display a progress form. Since there are about a dozen different ways of doing this, it's a bit hard to help you with a description of "My code doesn't work, help!"

As Dave said its hard to help you without more details. But my guess would be you do you operation in the same thread as the GUI. If you do this the GUI doesn't get the time to repaint itself. If this is the case you have two options:
1. Make your search in a seperate thread (better).
2. Try to call System.Windows.Forms.Application.DoEvents() regulary - but not too often (faster to implement but not very clean and probably slower).

My search and the GUI were in a single thread. Thanks for your help and sorry for a lack of more information (to both you and Dave), but I think you have given me the direction in which to go in to solve my problem.

I'm working on an image processing application and I was convinced to do this in C#. I am not very familiar in this language and my problem is that I don't know how to display multiple images in the same workspace. I thought this could be solved with PictureBox. Could anyone give me suggestions? I thank thee in advance.
|

Its not very clear what exactly you try to do. You can put several pictureboxes onto one form and display one image in each of them. If you want to show several images dynamically you can either add one PictureBox for each image at runtime or have a look a this article.
|
|
|
|
|
I wonder if it is possible to show more than one image in a picturebox.
In Java for example it is easy to display multiple images at specific coordinates in the same box at the same time.

No the normal PictureBox shows only one image. If you need this you will have to do it yourself. But its easier as you might think. Just create a new class inheriting from control, override the OnPaint method and draw your stuff:
public class MultiImageControl : Control {
private Image[] _images;
private Point[] _points;
public MultiImageControl(Image[] images, Point[] points) {
_images = images;
_points = points;
}
protected override OnPaint(PaintEventArgs pea) {
for (int i = 0; i < _images.Length; i++)
pea.DrawImageUnscaled(_images[i], _positions[i]);
}
}
Note that this will not be accessible in the designer. For this some more work is needed.

Getting the following error when trying to switch from Code to Designer for any smart device project:
Unable to cast COM object of type 'Microsoft.VisualStudio.DeviceConnectivity.Interop.ConManClass' to interface type 'Microsoft.VisualStudio.DeviceConnectivity.Interop.ICcServer'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{EA537AF4-2226-4D26-BBC0-9CF3A82749A5}' failed with HRESULT: 0x80004002 (No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))).
Any help appreciated.

Thanks LongHC - although I sense it has something to do with my configuration of VS2005, I reported it as a bug.

When you click the link for the source code, click Save, not Open!! Save the .ZIP file somewhere, then open that saved file.

Hi
I am currently writting a program that read a file which contains some information. I will enter a loop that will loop 10000 or even 25000 times(depending on the number of lines)to enter these information.
Now, is it a good practice to open the connection to the database and close it within the loop.So it will be opened and closed each loop.If not, what is the best solution?!
I mean, will it affect the time performance??
My database is MS Access 2003
Thanks
|
|
|
|
|
I think it would. I'd just open the connection right before you start the loop and close it afterwards.
|
|
|
|
|
Thanks I will try
Q:Where can I find a reference that shows me when I should use the executeQueri() method and when I shold use the execute() method of the database?
regards
