I believe most of this was to do with a time difference between the client and the server.
Future tests showed that my software worked with a Kerberos token for 'n' amount of time, and then I would start getting errors. I'm not talking about, constantly working. I mean, closing the application and starting it again, I would still get bizarre Kerberos token errors.
I've therefore stopped using it. It was a good at the start, but too unpredictable.

All,
I am currently working on a program that has a couple different classes that are called from the main windows form. I would like to be able to show the status when one of these classes is called, either by text or by a progress bar. For instance, when a method runs in a class I have called, I would like to be able to say show the name of that method on the windows form. Please forgive me, I am only 6 months into C#!

You should probably consider reading about Debug.Assert() or Write(), you could put that wherever you want to note that youre calling a method at runtime, and it will be output to your output window in vs.net

Hi,
I'm using the AxWebBrowser component in a c# application. Is there a way to disable javascript error messages or at least ensure that they don't pop out in an alert box. i've tinkered with IE setting in the advanced tab to disable notification, and i don't get pop up error messages in IE anymore, but i still get them in my app.
Is there any way to get around this? is there a way to intercept these warnings from code and handle them?
Please, help! Thank you very much.

To prevent javascript error messages in your mshtml web browser, set the Silent property of your web browser control.
this.axWebBrowser1.Silent = true;

Graphics g = this.CreateGraphics();
g.DrawImage(g, new Rectangle(new Point(0,0), new Size(40, 70)), 30, 40, 40, 70, GraphicsUnit.Pixel);
myImage = g.???????
how can i convert a graphic object to Image or how can i draw a graphic object inside an image object?

No, not at all. Thing about Graphics object like about drawing surface.
btw AFAIK Graphics.DrawImage() method doesn't take Graphics object as parameter... Does this compile:

 ?
Use static Graphics.FromImage()[^] to perform drawing into Image object, or pass Image as argument to Graphics.DrawImage method if you want to draw image INTO that Graphics (surface).
Does it help?

ok but how can i draw the contain of that g graphic inside an picturebox?
|
|
|
|

And you write it *where* with Graphics object?
Usualy you do that like:
Image img = new Image();
using( Graphics g = Graphics.FromImage( img ) )
{
g.DrawLine(...)
..
}
pictureBox1.Image = img;
and all that drawing will be applied to that image. ( I hope  )

i use this code:
Image tmp1 = Image.FromFile(path);
Graphics g = Graphics.FromImage(tmp1);
g.DrawImage(tmp1, new Rectangle(new Point(0,0), new Size(40, 70)), 30, 40, 40, 70, GraphicsUnit.Pixel);
pictureBox1.Image = tmp1;
but it draw the perfect original tmp1 image without cutting...
|
|
|
|

I am not sure why, but problem is that you use same object as source and destination...
Image tmp1 = Image.FromFile("../../Bitmap1.jpg");
Image img = new Bitmap(100,100);
Rectangle srcRect = new Rectangle(0,0,50,50);
Rectangle destRect = new Rectangle(0,0,20,100);
Graphics g = Graphics.FromImage(img);
pictureBox1.Image = img;
g.DrawImage(tmp1, destRect, srcRect, GraphicsUnit.Pixel);
g.Dispose();
tmp1.Dispose();

i've loaded a png file.
now i want to cut a rect from it and draw in a specific Top-Right position of a picturebox.
What functions i heve to call?

Make a brush form this image.
|
|
|
|

i know there is image.fromRect or functions similar, but i don't remember.
|
|

|

No,in the Brush class you cna make Brush.FromImage ,try it.

Hope this helps
public void Clone_Example(PaintEventArgs e)
{
// Create a Bitmap object from a file.
Bitmap myBitmap = new Bitmap("Grapes.jpg");
// Clone a portion of the Bitmap object.
RectangleF cloneRect = new RectangleF(0, 0, 100, 100);
PixelFormat format = myBitmap.PixelFormat;
Bitmap cloneBitmap = myBitmap.Clone(cloneRect, format);
// Draw the cloned portion of the Bitmap object.
e.Graphics.DrawImage(cloneBitmap, 0, 0);
}

ok now if i want to draw cloneBitmap in a particular position of a pictureBox how can i do?
Becouse i've tryed to do this:
pictureBox1.Image = cloneBitmap;
and it draw nothing while pictureBox1.Image = myBitmap; yes
|
|
|
|
|
OK I've found the problem!
I load a png file so i can't execute the cutting.
I don't know why but if i load bitmap and i try to cut it it works!
Someone can tell me why?
How can i do about using png files?

When I wrote my firs (and only  ) "self updating" program, I use teh following method:
- I create a static string in teh code for the version number
- I create a folder in my website in the folder there is a textfile called version.txt contains only one line, the current version number, and int his folder also in the new verson of tehe .exe and a nother file called updater.exe
- when my app starts meka a web request, and read the version number from the version.txt and if it's not same as the number in the exe:
- download the updater.exe, and run it
- the updater.exe close the real app, and download the new app.exe from the web
- then start it, and close themselves
- now, the new version is on the machine, and run
Perhapes the app delete the updater.exe from the computer, vhen finishing the update 
I know It's a crazy, nd maybe stupid way, but when I do this I haven't a better idea, and It's work fine 
But the exper CP aunthors shud tell you a better way :->

You have to design your application to be "easily upgradable" at the first place  Take a look at Razor Framework[^].

I am using image streams to set the images of my toolbar.
If I close the streams, I get generic GRI+ error. On the other hand
if I dont close them, the error is resolved.
Any ideas?

Straight from MSDN Image.FromStream docs:
Remarks<br />
You must keep the stream open for the lifetime of the Image object.
I created a Bitmap helper class that copied the bytes to MemoryStream and managed the Bitmap from there. Here are some of the methods of the class:
public void Load(Stream sm)
{
Clear();
int len = (int) sm.Length;
byte[] buf = new byte[len];
sm.Read(buf,0,len);
_ms = new MemoryStream(buf);
_bm = (Bitmap) Image.FromStream(_ms);
}
public void Load(string fileName)
{
FileStream fs = new FileStream(fileName,FileMode.Open,FileAccess.Read);
Load(fs);
fs.Close();
}
public void Load(object dbField)
{
Clear();
if (dbField != DBNull.Value)
{
byte[] buf = (byte[])dbField;
_ms = new MemoryStream(buf);
_bm = (Bitmap) Image.FromStream(_ms);
}
}
public void Clear()
{
if (_bm != null)
{
_bm.Dispose();
_bm = null;
}
if (_ms != null)
{
_ms.Close();
_ms = null;
}
}
public Bitmap Bitmap
{
get {return _bm;}
}
