i have a new form inheriting from another form. the new form has a datagrid in it.
i'm creating a table style so my datagrid cells will fill the entire width, but my datagrid.width is not working correctly. it gives out a width entirely too small.
for example:
. . . . . . . .
DataGridTextBoxColumn ProductID = new DataGridTextBoxColumn();
ProductID.HeaderText = "Product";
ProductID.MappingName = "ProductID";
ProductID.Width = 100;
DataGridTextBoxColumn Comments = new DataGridTextBoxColumn();
Comments.HeaderText = "Comments";
Comments.MappingName = "Comments";
Comments.Width = dg.width - 100;
. . . . . . . .
the Comments column is very small. i've used this in other applications, but this one is acting funny. i'm wondering if it might have to do with the inheritance. ( note, the datagrid is not being inherited )

well you have to account for row header size - a few pixels, plus it rounds. jusy play with it
Column.Width = dg.width - dg.rowheaderwidth -3;

And next, autosize Your column in OnPaint method  . Another events work poor

Hi guys,
Sorry to bother you with such a dumb question, I've been trying to figure it out for days now. All I want to do for an application is that after reading in data from a file (I've done), I want to graph it (I know how to graph) in different ways in different windows. Basically my question is how do I, upon user's command from a menu choice, bring up a new window, a new window and assign a certain view to that window.
In summary I have about 10 different views(with a different graph on each view). What I want to know is how do I, anytime a user wants to see one of them, display a new window on top(MDI) with the according view attached to that window.
Please could you reply with an answer.
Thank you respectfully
Raj Qbus Surendra

Does anyone knows how to create a class which will calculate Net Volumes from Pressure, Temperature and gas quality according to AGA (AGA-3, AGA-5 AND AGA-8) standards?
Thanks. Mike

look up the formulas and move them into methods

Hi
I am trying to load a texture from an image I get from a Web Service. D3D provides a method TextureLoader.FromStream using which you can load a texture from a stream. This is the code I wrote to load the texture:
imageRequest = (HttpWebRequest)WebRequest.Create(URL);
URL is something like http://terraservice.net/ogcmap.ashx?version=1.1.1&request=getmap&layers=drg&styles=utmgrid_yellow&srs=epsg:4326&bbox=-122.427,36.66,-117.756,38.947913&width=1000&height=500&format=image/jpeg
imageResponse = (HttpWebResponse)imageRequest.GetResponse();
imageStream = imageResponse.GetResponseStream(); // get a "Stream" from the "Response" object
TextureLoader.FromStream(device, imageStream);
But TextureLoader.FromStream() fn. Gives an error message that “stream does not allow seeking”
Then this is the second thing I tried:
imageRequest = (HttpWebRequest)WebRequest.Create(URL);
imageResponse = (HttpWebResponse)imageRequest.GetResponse();
imageStream = imageResponse.GetResponseStream(); // get a "Stream" from the "Response" object
byte[] buffer = new byte[imageResponse.ContentLength];
imageStream.Read(buffer, 0, (int) imageResponse.ContentLength);
// imageResponse.ContentLength is long so have to cast to int
MemoryStream stream = new MemoryStream(buffer);
texture = TextureLoader.FromStream(device, stream);
but imageResponse.ContentLength is always equal to -1. I was able to save the image by doing:
Image img = Image.FromStream(imageStream);
img.Save("c:/junk/texmap.jpg", ImageFormat.Jpeg);
and it came out fine when i opened it in photoshop.
Then I tried following code (replaced imageResponse.ContentLength by imageStream.Length):
imageRequest = (HttpWebRequest)WebRequest.Create(URL);
imageResponse = (HttpWebResponse)imageRequest.GetResponse();
imageStream = imageResponse.GetResponseStream(); // get a "Stream" from the "Response" object
byte[] buffer = new byte[imageStream.Length];
imageStream.Read(buffer, 0, (int) imageStream.Length);
MemoryStream stream = new MemoryStream(buffer);
texture = TextureLoader.FromStream(device, stream);
but this gives following error while trying to access imageStream.Length while executing
byte[] buffer = new byte[imageStream.Length];
exception of type 'System.NotSupportedException' occurred in system.dll
This stream does not support seek operations.
Any ideas what to do?

For getting Pictures from Webpages i use following Code:
---------------------------------------------------------------
WebRequest request = WebRequest.Create("<urltofetch>");
WebResponse response = request.GetResponse();
Stream stream = response.GetResponseStream();
Stream local = File.Create("filename.gif");
byte[] buffer = new byte[1024];
int n;
do
{
n = stream.Read(buffer, 0, buffer.Length);
local.Write(buffer, 0, n);
} while (n > 0);
stream.Close();
local.Close();
---------------------------------------------------------------
Where the url can be whatever you want ...
Hope this will help!

How can I get rid of the beep that happens when I press enter on a form with no default button?
|
|
|
|
|
Add a default button? It seems to me that every form should have a default button, no?

Unless the application is a simple, one form, dialog application.
Have you tried catching the key down event?
|
|
|
|
|
I tried, but it didn't seem to work.
But I fixed it with a default button that's positioned outside the form 
|
|
|
|
|
Ouch. That seems like a bit of a hack. What did you try in terms of capturing the Enter key?

What's 'ROTOR'??? I've been hearing alot about that lately...
and instead of actually going to the link provided by the message below this, and finding the answer in 10 seconds. I'd much rather wait a day and, have my question answered here.

partial sample .net implementation from microsoft with source code (to say it shortly)
|
|
|

Rotor is the codename (friendly name?) for SSCLI, the Shared Source Common Language Infrastructure. Essentially it's the source for a shared source C# compiler and CLR. If you download it you can see the source for a garbage collector, a C# compiler, how to run managed code in a "sandbox" etc, etc. Of course, there are millions of lines of C** and C# code in there, so it can be a little obtuse <g>.

So, what... Is it like a ghetto .NET???

No, it's for the official standardization of the C# language and the CLR for the ECMA. A "reference" version, if you like.

I am trying to create a Windows Form using C# that can load a dll from the client machine. The dll, uses a COM server to communicate with the COM ports.
The code looks like this so far:
public const string CPH_DLL = "cimphone.dll"; // Import library for Kernel on Win32
[DllImport(CPH_DLL)] public static extern int PingPhone(StringBuilder port);
[DllImport(KER_DLL)] public static extern uint LoadLibrary( string lpFileName );
uint m_hModuleOGL = LoadLibrary(CPH_DLL);
PingPhone("COM2");
The problem is that it is loading the dll on the server and accessing the port on the server. I need it to run on the client running the form.
Any suggestions or tutorials on this subject?

 is there a way to use c# to communicate with the parallel port efficiently. i.e without COM and winows dll imports.
