hai all ,
we used below method for get the image data from database,it is working fine in desktop computers ,but it is not working in laptops.it is showing below error only in laptops.
Error Message:
out of memory:at System.image.fromfile(string filename,boolean useembeddedcolormanagement) at System.Drawing.image.fromfile(String Filename)
Please help me.
public void getimages()
{
bigImgLst_Vendors.Images.Clear();
smallImgLst_Vendors.Images.Clear();
string path;
path = Path.GetDirectoryName(
Assembly.GetExecutingAssembly().GetName().CodeBase);
path = path.Replace("\\bin\\Debug", @"\Transaction\Contacts\Photos");
path = path.Replace("file:\\", "");
string imageDirectoryPath = path;
string[] files = null;
if (Directory.Exists(imageDirectoryPath))
files = Directory.GetFiles(imageDirectoryPath);
if (files != null)
if (files.Length > 0)
for (int i = 0; i <= files.Length - 2; i++)
if (File.Exists(files[i]))
{
//foreach (ListViewItem vcontext in lvw_VendorList.Items)
//{
//if(vcontext.Tag == (files[i].Split('\\'))[files[i].Split('\\').Length - 1])
bigImgLst_Vendors.Images.Add((files[i].Split('\\'))[files[i].Split('\\').Length - 1],
Image.FromFile(files[i]));
smallImgLst_Vendors.Images.Add(
(files[i].Split('\\'))[files[i].Split('\\').Length - 1], Image.FromFile(files[i]));
//}
}
int imageIndex = -1;
int NoImageIndex = 0;
NoImageIndex = bigImgLst_Vendors.Images.IndexOfKey("NoImage.png");
lvw_VendorList.LargeImageList = bigImgLst_Vendors;
lvw_VendorList.SmallImageList = smallImgLst_Vendors;
lvw_VendorList.StateImageList = smallImgLst_Vendors;
foreach (ListViewItem vcontext in lvw_VendorList.Items)
{
if (vcontext.Tag != null)
if (vcontext.Tag.ToString().Trim() != "")
imageIndex = bigImgLst_Vendors.Images.IndexOfKey(vcontext.Tag.ToString());
if (imageIndex != -1)
vcontext.ImageIndex = imageIndex;
else
vcontext.ImageIndex = NoImageIndex;
imageIndex = -1;
}
}

It has nothing to do with Laptop or Desktop.
I also had to write code that generating thumbnails some time ago. .NET throws OutOfMemoryException if it does not recognize the image format.
This happen for example when loading the image file whose format is unreconized/unsupported by .NET. Methods might raise this exception
include Image.FromFile, Bitmap constructor, etc, see their "remark" section. You should debug your app to see if it is the cause.

Correction to my previous post.
I have created a windows application.
There are forms inside the windows form application project. There is a class library project too.
The .sln is in the following path:
C:\Work\Developments\SQLchecks\SQLchecks
The windows forms are inside the windows application project as below:
C:\Work\Developments\SQLchecks\SQLchecks\SQLchecks
There is a class library project called DataAccess which has classes and an xml file called Settings.xml :
C:\Work\Developments\SQLchecks\SQLchecks\DataAccess
Question:
from within a class inside the DataAccess project which is a class library project, how do I refer to the Settings.xml file which is also in the same directory?
Thanks

This is just plain rude to the other posters, and you can always modify your original post.

I agree. There is nothing more annoying that the one message board for our local mountain communities that some knitwits post something like *Bump* just to keep the thread alive. Some of the threads died for a reason

hello,
i just want to know how can i create a Progressbar that represent the progress of a specific Form.
i mean, i have a Form with a lot of steps..that caculate a lot of things.
while wating that this progress will finish, i want to see the progress in the progressBar..
How can i do it?
thank you

Add the progress bar component to the form that you want to show it on. Set the maximum value to the number of steps you need to perform, and increment the value by 1 after each step completes.

DO you have any link that shows to me how to do it?
thank you

Really. Do I need to put a link on here for you? Why don't you try it out for yourself, as this is the best way to learn?

Thank you..it was very helpful..

Put a ProgressBar on the form and modify the Value property according to the progress that it is being made. You'll have to calculate that as a percentage yourself. (assuming that you show it like x %)
|
|
|
|
|
FYI you can set the maximum value so you don't need to calculate percentages.
If you have 5 steps, set the Maximum to 5 and increment the value by 1.

You can calculate a percentage for textual output in addition to a progress bar (I think that's what blackjack meant) by dividing two doubles... of course you should know how to compute a percentage.
Then you can use string functions to round that to a certain number of decimal points, but alas, I don't know the exact syntax.

thanks for your reply, but I fail to see that it could be useful for me

Well often a textual percentage is displayed on the progress dialog as well, or in its title bar so it can be seen on the task bar.

If you have to do heavy calculation.
A Better idea is to do it 'a part' in another thread.
Use thread safe methods to update your progress bar
|

Thank you!!!

you can use BackGroundWorker For that. becuase if you used progress bar for heavy operation your GUI will not respond becuase it give the priority to operation not GUI so your progress bar will not refresh. use BackGroundWorker Components in C#. that will help you.
cheers,

I second that. Threads are always best for long-running background operations, just remember to perform control updates on the control thread, as lisan mentioned.
Using threads will also allow you to have a "Cancel" button that can abort the background operation (if you periodically check for a canceled state in that thread, since actually aborting threads can be dangerous).

A webservice connects with a server. Do you know anything about web services, or did you just hear about them ? What are you trying to do ?

I have a small problem with a file copy loop the code,
During the loop some of the files encounter a System.UnauthorizedAccessException now i would like it just to skip this file and continue with the loop (copy the rest of the files) but it seems the top layer catch fires and it stops copying.
Code basically looks like this:
Private void dostuff()
{
try
{
CopyDirectory(@"c:\test");
}
catch
{
reporterror();
}
}
Private void CopyDirectory(string target)
{
string[] files = Directory.GetFiles(target);
foreach (string file in files)
{
try
{
File.copy(file, @"d:\")
}
catch
{
}
}
}
Thanks for reading!
