I should have gone back and read the sample code with both eyes open! Hmmm...
OK. This may seem stupid, but did you put this at the top of the code?

Ok, yes I'm stupid and cannot read examples clearly 
You need to have a /**@delegate*/ over the delegate deklaration. Odd in my opinion, oh well.

Hello,
Is it possible to get attributes of a Xml-file and place it in a datagrid. The second column then should be a boolcolumn. Then when i press a button "save" i want the attribute with the true or false value saved in another Xml-file.
Is this possible or to difficult to do?
thx in advance.
for example: the first xml-file looks like this:
<tablegroups>
<tablegroup name="programs">
<description>program dictionary</description>
</tablegroup>
<tablegroup name="parameters">
<description>parameter system</description>
</tablegroup>
</tablegroups>
Then the result should be:
<tablegroups>
<tablegroup name="programs">true</tablegroup>
<tablegroup name="parameters">false</tablegroup>
</tablegroups>

When you read an XML file into a DataSet (to bind to a DataGrid or any other data-bindable control), attributes on "table" elements are treated as columns as well as the child elements.
If you want to save your DataSet in a different format, then you should either use an XslTransform to transform the data before saving to disk or just use the XML DOM classes (in System.Xml) to do so manually. The nice thing about XML is that you can do just about anything you want with it if you know how. It's really not hard. I suggest reading the System.Xml namespace member documentation, as well as the many XML topics in the .NET Framework SDK.

aferter using Bitmap.Save("bmpname.gif",ImageFormat.Gif) method,
i can get a bmpname.gif file.
why the file is filled with many white dots ?
|
|
|
|
|
sorry my mistake.
the bmpname.gif image is full of noise.
while using paint.exe to convert a bmp to a gif , the image looks smooth.
Why ?
|
|
|
|

Were there any "holes" in your Bitmap image before you saved it, like alpha channel data? Actual holes in the image?
Alpha would be my first guess...
The GIF format doesn't support alpha channels, so these would end up becoming holes in your image. GIF supports a transparency key where one color can be picked and, when rendered, that color doesn't get painted on the screen so the background behind the GIF image shows through.

emmm, maybe i got something from your speech.
here is my Saving progress:
Bitmap bmp = new Bitmap(@"D:\1\111.bmp"); // 111.bmp is a 24bits bmp saved by paint.exe
bmp.Save(@"d:\1\111.gif",ImageFormat.Gif);
only 2 lines codes above. maybe the 111.gif lose alpha info after convertion.

Yes it does lose the alpha, because the GIF format doesn't support it, so there are your "holes" in your GIF image.

Hi,
I am consuming a webservice from my C# component(which will be used by lots of applications), basically i want the to return and specific number -200 when the webservice is down.
Can any one suggest me how can i do it?? I am planning to put multiple exception blocks, like application exception,web exception,protocol exception etc, does that work??
Any pointers to this will be helpful.
TIA,
sudheer

You can't put it in the WebService because if it's down, how is it going to return a value? Especially if there is a network problem...
Your consumers will have to handle the exception themselves and, if required, set the return value to -200 in their exception handlers.

In addition to what Dave said, you can either handle multiple exception types or catch them all like so:
try
{
}
catch (WebException ex)
{
}
catch (ApplicationException ex)
{
}
catch (Exception ex)
{
}You could also catch all exceptions like so:
try
{
}
catch (Exception ex)
{
}If you don't plan on using the exception info, you can either use an empty catch like:
try
{
}
catch
{
}...or catch specific exception types like:
try
{
}
catch (WebException)
{
}
catch (ApplicationException)
{
}
catch (Exception)
{
}

hi,
this is the way how you do it ...
private void button1_Click(object sender, System.EventArgs e)
{
TextBox tb = new TextBox();
tb.Width = 100;
tb.Location = new Point(100,100);
this.Controls.Add(tb);
}
Hope this solves your prob..
regards,
Aryadip.
Cheers !! and have a Funky day !!

If you want to see all textbox which added to the form.then you can use the below mentioned code block
private void button1_Click(object sender, System.EventArgs e)
{
Txtbox= new TextBox();
this.Txtbox.Location = new System.Drawing.Point(locx, locy);
Txtbox.Width = 100;
this.Controls.Add(Txtbox);
locx=Txtbox.Location.X;
locy=Txtbox.Location.Y+30;
}
//here i have only one button on my form. On button click i am dynamically creating
//textbox control and adding to the control collection of form.
//before getting into code you have to declare one private datamember of the type textbox and two integer variables that will help you to keep the location unique.
so you can avoid overlapping.
private System.Windows.Forms.TextBox Txtbox;
private int locx=20,locy=30;
hope this will avoid from overlapping

If I want to use special cursor image other than the default list given in .Net environment, how to add new image to the list of available images.
|
|
|
|
|
You can not in the default list.
After creating a cursor you use it through your own class.
|
|
|
|
|
On desigh time you have only limited number of cursors.
but on run time you can change you cursor of form or any control which is avilable in your application.
where you want to write code is up to you.
eg: if you want to change the cursor of the form on form_load or button click event , what you need to do is simply write this code.
this.Cursor=new Cursor("C:\\DRAGPICT.CUR");
//here i am changing cursor of my form.
// if you want to change the default cursor of any control. then follow this
this.button.Cursor=new cursor("C:\\newcursor.cur");
hope this will help you

Hi,
I would like to save files into the "Temporary Internet Files" folder.
How do you set the path when the user is different each time?
string path = "C:\\Documents and Settings\\<user>\\Local Settings\\Temporary Internet Files\\";
thanks,
Ron

You really shouldn't do that because the folder has a special purpose that is not under your app's control, and can be wiped out without you knowing about it.
But, if you must...
You can use the Environment.GetFolderPath method to return the full path to the Temporary Internet Files folder for the logged in user:
string tempInternetFilesFolderPath
tempInternetFilesFolderPath=Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);

Hi Dave,
Ya... I'm not sure. I'm trying to emulate the feature "Send" in WordPad (e-mail your document). I noticed that WordPad is saving a copy of the doc in the folder OLK63B in Temporary Internet Files (this file is used for the attachment). I guessing they're doing this so the file is flushed eventually? I can't actually see this folder "OLK63B" when I use Windows Explorer though. They must be creating a copy file so your not having to save the modifications (if any) before you send. Maybe I should just (via my code) create a copy file (append with the word "COPY") and delete the file after sending. What do you think?
Ron

That will work. You could even just create the file in <SystemRoot>\Temp with the original filename, attach the file to the email message, send the message off, then delete the temp file. I'd use the original filename (unmodified) so the user at the other end can save the file with the same name it was created with.

Thanks Dave,
I'll do just that...
I'm new to programming, so I'm not sure just the best way to delay the delete of the file (so that Outlook has time to load/place/send the attachment). I could use a MessageBox (Click OK to delete attachment file), but that seems cheesy. Can you use code to tell when any running application closes?
Ron

You could use the Process class to monitor the process list for the close, but that would involve either launching a seperate thread to poll the process list every so often, or blocking your app and waiting for the Outlook message window to close. Also, the problem with that is if the user is not using outlook, but a different email package the process will be different.
There is no easy way to do this except to NOT make a copy of the file and just send the original file and not worry about monitoring anything and deleting files.
