WHAT exception?
Is the server configured to not accept POST?

"The underlying connection was closed"
The site works fine in a browser, once you get past the security error, so I assume that the server does accept post.
Is it somehow possible to ignore the certificate errors for the webbrowser control?

byte[]imgdata= new byte[stream.Length];
imgdata= stream.ToArray();
string Filename = "c:\\" + Convert.ToString(DateTime.Now.ToFileTime()) +".jpg";
FileStream fs = new FileStream(Filename, FileMode.CreateNew, FileAccess.Write);
fs.Write(imgdata, 0, imgdata.Length);
fs.Close();
}

This might be ExternalException ,which means that you are trying to save the image using invalid format.Try to replace in your code System.Drawing.Imaging.ImageFormat.Jpeg
with image.RowFormat.Notice that .jpg or .jpeg extensions could not guarantee that the format is Jpeg.

hi.tanks for answering.
but this again throw exeption.please help me.
|
|
|
|

The which kind of exception and where exactly it occurred?
Make sure that Image.RowFormat is not equal to Emf, Exif, Icon, MemoryBmp Wmf,which might be not supported by the Image.Save(Stream,ImageFormat) method used into your code.

I have a similiar situation when saving an image, no matter what type.
It's a local winform client application. When I'm logged onto the machine (I am admistrator) it works fine. When other users without admin rights are logged on, the generic GDI+ error occurs while saving the image. Any ideas on how to get around this?
Using Image.Save taking a .png, .jpeg, or .bmp file types, seems to make no difference.

Same sh*t.
Save method creates file, but doesn't write.
And the very strange is GDI+ error. As soon as I know it doesn't return any error besides cases when the pointer to Image raw data is not returned.
In fact, GDI+ deals with windows context (Device Context) of the control where image is shown.
Therefore, it might be GDI+ API can't get the control's handle or doesn't has an access right to the control.. maybe .NET blocks the access to its controls from outside dll request.
From other side all components are in the same thread, though maybe this Save operation opens new thread????
Any idea?

You need to use the ViewerPreferences entry in the document catalog. Refer to the PDF specification document from Adobe for details.

Take a look at the documentation for PathGradientBrush class and its SurroundColors property.

Crystal report Tile, can it be changed in the same report? For example, after the first two pages the title will change to something different ... this goes on ... after a few pages, the title changes again to a different one.

Hi,
my datatable contains the following columns...
resultsView.Columns.Add("Fam.", typeof(string));
resultsView.Columns.Add("Component", typeof(int));
resultsView.Columns.Add("Description", typeof(string));
resultsView.Columns.Add("Quantity", typeof(double));
resultsView.Columns.Add("Unit", typeof(string));
resultsView.Columns.Add("Unit Price", typeof(double));
resultsView.Columns.Add("Total", typeof(double));
i have a datatable,
I use IEqualityComparer to get distinct rows.
Im able to get the distinct rows...
What my problem is If i find same rows, i need to increase a columnValue in this datatable.
I mean i have column named "component" in my datatable, so if two rows are same, then i need to get one row with component value increased by 1 using IEqualitycomparer. What i get now is only one row with component column value not increased...
cud anyone plz help me to solve this problem??

It is difficult to help you without seeing the code you are using.
Please post your code. If you do so then please put the code between <pre>your code here</pre> tags to maintain the formatting and make it readable.

thanks for ur reply,
here is my code....
my datatable(named as sortedDataTable) has columns as in my previous message... and i use iequalitycomparer as below
IEnumerable<DataRow> drdistinct = sortedDataTable.AsEnumerable().Distinct(new MyDataRowComparer());
in my iequalitycomparer class i have these codes...
<pre>
class MyDataRowComparer : IEqualityComparer<DataRow>
{
public MyDataRowComparer()
{
}
public bool Equals(DataRow x, DataRow y)
{
if (x.Field<string>("Fam.") == y.Field<string>("Fam.") && x.Field<string>("Description") == y.Field<string>("Description"))
{
x["Component"] = Convert.ToInt16(x["Component"]) + 1;
x["Quantity"] = Convert.ToDouble(x["Quantity"]) + Convert.ToDouble(y["Quantity"]);
//y.Delete();
return true;
}
else
return false;
}
public int GetHashCode(DataRow obj)
{
int a = obj.Field<string>("Fam.").GetHashCode();
int b = obj.Field<string>("Description").GetHashCode();
// obj["Component"] = Convert.ToInt16(obj["Component"]) + 1;
//x["Quantity"] = Convert.ToDouble(x["Quantity"]) + Convert.ToDouble(y["Quantity"]);
return a + b;
} </pre>
these code, works fine and it returns me only the distinct rows, but this gethashcode method adds the first row and then compares it with subsequent rows, so if i apend column values in equals method as in above, it doesnt affect the datatable as it adds the row in the begining itself..

It seems to me that your problem would be better solved by a properly constructed Stored Procedure in your database.
I am not particularly good at SQL so if this idea appeals, you might get a better solution in the General Database Forum.
However, something like:
SELECT
Fam., Description, etc.,
SUM(Component) AS "Component Total",
SUM(Quantity) AS "Quantity Total"
FROM
your_table
GROUP BY
Fam., Description
