Is it necessary for your program to be fetching all fields from all records in the LocalDB table?

No worries about the actual ram. If the system runs out, then it'll go to virtual memory on the hard drive. As slow as that is, it's better than nothing.
Take a closer look at the requirements of your program and see where you can trim out unneeded data ( such as fields you are not working with)...

Bitmap bm = new Bitmap(@"C:\LEGO.jpg");
Graphics gr = Graphics.FromImage(bm);
gr.DrawEllipse(Pens.AliceBlue, new Rectangle(5, 5, 50, 50));
gr.Dispose();
bm.Save(@"C:\LEGO.jpg");
Error:
System.Runtime.InteropServices.ExternalException was unhandled
A generic error occurred in GDI+.
I know the loaded bitmap file is still locked and there will be no error if saved with a different name, but I want to apply my changes to the same file, is it doable?? How??
Many thanks!

You can save it with different name, delete old one and rename the one you created.
|

You can user the "Clone()" function to get a new bitmap object and dispose the original one.
some thing like:
Bitmap bm = new Bitmap(@"C:\LEGO.jpg");
Bitmap tmp = bm.Clone();
bm.Dispose();
Graphics gr = Graphics.FromImage(tmp);
gr.DrawEllipse(Pens.AliceBlue, new Rectangle(5, 5, 50, 50));
gr.Dispose();
tmp.Save(@"C:\LEGO.jpg");
hope this helps.

Open a file stream and read the image from the stream. That way you can close the stream so the file is not locked.
Despite everything, the person most likely to be fooling you next is yourself.

Thanx Guffa! It works now

Guffa was correct. The problem is that your first line of code, Bitmap(@"C:\LEGO.jpg");, is locking, by design if the Image class Bitmap derives from, the file it loaded for the lifetime of the Bitmap object. So, to get around this limitation, you have to read the .jpg file yourself using a StreamReader, then create the Bitmap from the StreamReader object. This will prevent the file from being locked so you can Save the new image file over the old one without getting that error.

Thanx Dave, but did you actually try this solution?? Does it work with you?? How can you do it with stream reader?? Did you mean FileStream?? And if so, it still doesnt work even after closing it!

Sorry, using a FileStream works. Yes, I have done it and, yes, it does work. There's something else you're doing, or not doing correctly that's keeping the file locked. See this[^].

Hi
Is there any tools in visual Studio 2008 Team Suite for Team Working (Like Visual Source Safe) ?
if so, can any one give me a useful article for working with it ?
thanks
|
|

Team Foundation Server (TFS) is the source control & bug tracking server from MS, I can't remember if it comes with Visual studio team suite or if you have to buy it separately (Probably depends on if you have an MSDN license or not).
There are other non-ms alternatives to source safe too. Just google for source control. (Subversion, Perforce, CVS, Git are just a few)
(Comparisom of source control software[^])
If you need bug/issue tracking as well, there are also plenty of options (Bugzilla, BugTracker.net, FogBugz, Trac are a few I can think of). (Comparisom of bug tracking software[^])

Thanks Simon
can i use Source Safe for Visual Studio 2008, Instead of TFS ?
|
|
|
|
|
Yes you can, but a lot of people are very critical of source safe. We use it and I don't like it. There are plenty of better options out there. If you have MSDN and TFS it is much better, I've used it in the past and it is good. Check out some of the other ones on the list, if you can't afford TFS.

i want to save a image form serialization....
hghghgh

|

|

Thats nice. Not really a question though is it?
So, where about are you? Do you have a stream which represents the image? If so, how did you get that image into the stream in the first place?
You've got to give at least a little bit of information to get any help.

[Serializable]
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
draw();
}
public void draw()
{
Graphics g = this.CreateGraphics();
Pen p = new Pen(Color.Red);
g.DrawRectangle(p, 23, 23, 78, 78);
}
using System.IO;
using System.Xml.Serialization;
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private static void Serialize()
{
Form1 obj = new Form1();
XmlSerializer mySerializer = new
XmlSerializer(typeof(Form1));
StreamWriter myWriter = new StreamWriter("C:\\myDrawing.xml");
mySerializer.Serialize(myWriter, obj);
myWriter.Close();
}
private static void DeSerialize()
{
Form1 obj = null;
XmlSerializer mySerializer =
new XmlSerializer(typeof(Form1));
FileStream myFileStream =
new FileStream("C:\\myDrawing.xml", FileMode.Open);
obj= (Form1)mySerializer.Deserialize(myFileStream);
obj.Draw();
}
private void Form2_Load(object sender, EventArgs e)
{
Serialize();
// Form1 f = new Form1();
// putIt objDele = new putIt(f.toi);
//objDele();
}
private void button1_Click(object sender, EventArgs e)
{
DeSerialize();
}
}
now i think its enough for understanding
?
