AVI could do the quality, however the transparency could be a problem. 1280x720 is a LOT of real estate to cover, if the entire area isn't being animated at the same time, you might be better off only redrawing the parts of the screen that change. Or moving a picture around the screen as the animation.
Aside from that, your next step would probably be using managed DirectX to pile all those graphics into buffers.

This response is nothing to do with your main problem, but Image.FromFile has been known to cause problems with files becoming locked. The general recommendation is to use Image.FromStream.

I am having an issue on a photo gallery that is random. I add a photo and it is supposed to save the location in an Access DB backend. It then has a thumbnail view for the photo. At random I get a red X instead of a thumbnail and get an error...its COMPLETELY RANDOM...if I clear the photo from that thumbnail and re-add it...it adds the photo, but continues to give me red X's and I have to clear and re-add...

Well my guess is that there is a problem loading the image from the database. Can you give more information and show the code you are using to load the picture from the database and loading from new.
Life goes very fast. Tomorrow, today is already yesterday.
|
|
|
|
|
The image loading is done by a "pictureBox.ImageLocation=" statement. It happens sometimes when loading and adding photos using right click. If you need some code can I email it to you.
|
|
|
|
|
put the code on here.
the thing with picture boxes is when you load them directly from a file they can cause problems with access to the files. When loading picture boxes it best to load it from a memory stream, something like this...
PictureBox1.Image = Image.FromStream(new MemoryStream("imagefile"));
Life goes very fast. Tomorrow, today is already yesterday.

|

|

Here you go...
This is the picture box creation code:
PictureBox pictureBox = new PictureBox();
pictureBox.Left = (i % 10) * 36 + 4;
pictureBox.Top = ((i / 10) + startRow) * 36 + 4 - galleryScroll;
pictureBox.Width = 32;
pictureBox.Height = 32;
pictureBox.BorderStyle = BorderStyle.FixedSingle;
pictureBox.ContextMenuStrip = pictureMenu;
pictureBox.Click += galleryPictureBox_Click;
pictureBox.Visible = true;
panel1.Controls.Add(pictureBox);
Below is the image loading thread:
delegate void SetupGalleryBoxCallback(PictureBox box, Image image, bool showError, string tooltip);
private void setupGalleryBox(PictureBox box, Image image, bool showError, string tooltip)
{
if (this.InvokeRequired)
{
SetupGalleryBoxCallback d = new SetupGalleryBoxCallback(setupGalleryBox);
this.Invoke(d, new object[] { box, image, showError, tooltip });
}
else
{
if (image != null)
{
box.SizeMode = PictureBoxSizeMode.Zoom;
box.Image = image;
}
else if(showError)
{
box.SizeMode = PictureBoxSizeMode.CenterImage;
box.Image = box.ErrorImage;
}
Program.tooltip.SetToolTip(box, tooltip);
}
}
void imageLoadingThread()
{
int count = (_galleryItems != null) ? _galleryItems.Count : 0;
Image errorImage = galleryLargePictureBox.ErrorImage;
for (int i = 0; i < _galleryPictureBoxes.Count; i++)
{
if (i < count)
{
object[] galleryItem = (Object[])_galleryItems[i];
String imagePath = (string)galleryItem[0];
String toolTip = (string)galleryItem[2];
if(imagePath != null)
imagePath = imagePath.Trim();
if (imagePath != null && imagePath.Length > 0)
{
try
{
Image image = Image.FromFile(imagePath.Trim());
setupGalleryBox(_galleryPictureBoxes[i], image, false, toolTip);
}
catch (Exception)
{
setupGalleryBox(_galleryPictureBoxes[i], errorImage, true, toolTip);
}
if (i == _galleryPictureBoxes.Count - 1 && imagePath != null)
addPictureBoxes(1);
}
else
setupGalleryBox(_galleryPictureBoxes[i], null, false, toolTip);
//Console.WriteLine("Comment={0}", (string)((object[])_galleryItems[i])[2]);
}
else
_galleryPictureBoxes[i].ImageLocation = null;
}
}

Hi,
I need to use VSConstant class present in Microsoft.VisualStudio.Shell.9.0 in my program.
To that effect, I add at the top of my .cs file:
using Microsoft.VisualStudio.Shell.9.0;
VS2008 (Standard version) says that Microsoft.VisualStudio.Shell.9.0 does not exist in the namespace. Am I missing an assembly reference? Note that I can locate the Microsoft.VisualStudio.Shell.9.0 assembly in C:\assembly.
The same problem occurs if I wanted to use Microsoft.VisualStudio.Shell.
I right clicked on the "Reference" in the solution explorer and wanted to add then a reference to Microsoft.VisualStudio.Shell.9.0 assembly. It did not appear in the .NET list. I browsed then with the BROWSE tab. I locate the assembly and pressed OK. Even though it looks like it was loaded, the reference does not appear anywhere and VS2008 is complaining.
Would you have any idea how to come out of this?
Thanks beforehand if you have any idea.
P.S.: I have also installed previously on this PC VisualC#2008 Express. Could this be the problem?

I'm guessing you need to download and install the Visual Studio Shell[^]

That is bad form AGAIN. It sounds like you are demanding that he help you. He doesn't owe you anything. No one here does.
About your question. That fact that people cannot understand your question is your fault, not theirs. Perhaps you need to study the technology you are attempting to use so that you may pose questions using knowledge and standard terms that people will understand.

I have several list collections(i.e list1,list2 list3...etc)
and i have one xml file(i.e data.xml).I am storing the xml data to my suitable lists(i.e edge data in list1, subpart data in list2 like this...)
Now after storing the xml data in list collections i want to save this data from list to data base.
Till my coding is doing fine working properly and date are geting save into database.
But this entire process is time taking and user does not know when this process will completeed.Basicaly the xml file is not fixed.i will get sevaral xml file with more or less data(data structure of xml file is same).
I want to implement the progress bar here to inform how many hours or minutes or seconds left to to finise the entire process from storing xml data into list to saving data in database
can anyone give me idea about it...
with regards

You can't really do this. When you think about it, progress is dependent on many factors outside your control, such as network latency, server load, type of operation to be performed, other processes running on your machine, and so on. So all you can do is give (at best), a rough approximation of how long it will take.
Most algorithms work by knowing how many operations need to be performed, and then start by calculating how long one operation takes - then extrapolating the total time from this. After a certain number of operations, this figure is refined because there is greater statistical sampling at this stage. This is done over and over, until the operation is finally completed.

The following code shows you how I created a DataSet and added it to the DataGridView.
To define the default column style, I added 2 columns to the DataGridView before and set their DataPropertyName.
<br />
DataSet ds = new DataSet();<br />
ds.Tables.Add();<br />
<br />
ds.Tables[0].Columns.Add("a");<br />
ds.Tables[0].Columns.Add("b");<br />
<br />
colColumn1.DataPropertyName = "a";<br />
colColumn2.DataPropertyName = "b";<br />
<br />
for (int i = 0; i < 10; i++)<br />
{<br />
ds.Tables[0].Rows.Add("a" + i, "b" + i);<br />
}<br />
<br />
dataGridView1.DataSource = ds.Tables[0];
Now I have the problem that I can't change any style (BackColor) of the rows that will be added by setting the DataSource.
Can I define it somehow in the DataSet (DataRow) OR is there any event that will be called after the row finished adding?
[I don't want to go through each row after the DataSource is setted and set the new style]

In that way i currently solved it:
<br />
private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)<br />
{<br />
int i = 0;<br />
<br />
try<br />
{<br />
dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.White;<br />
if (dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString().Contains(textBox1.Text))<br />
{<br />
dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.ForestGreen;<br />
}<br />
int ii = 1 / i;<br />
}<br />
catch<br />
{<br />
<br />
}<br />
}<br />
I used the RowPrePaint event. So everytime when the row will be painted there is a check if the BackColor should be changed.
I tested it with 1,000,000 rows in fullscreen and the performance is (not the best but) ok.
But if you have another solution, feel free to post it.

Instead of trying to set the background through code its better to use CSS.

I forgot: It's a Windows.Forms application. So i can't do it in that way.
But in Websites it's also a solution.
