So you made your own WindowsApplication1.encode.Image type (a class, a struct, an enum, can't tell without seeing your code), and now you are hoping it can be used where .NET is expecting a real image (that is a System.Drawing.Image)??

I create a web service witch generate a picture :
<br />
private System.Drawing.Image pictImage;<br />
public static Image GetImage(byte[] bytes, bool makeTransparent)<br />
{}<br />
then, i create a winforms application whitch present a costumer of this web service,
<br />
encode.Service rr;<br />
rr = new encode.Service();<br />
<br />
pictureBox1.Image = (rr.Picture("C:\\Documents and Settings\\Administrateur\\Bureau\\logo.jpg"));<br />
but there are an error : Error 1 Cannot implicitly convert type 'WindowsApplication1.encode.Image' to 'System.Drawing.Image' C:\Documents and Settings\Administrateur\Mes documents\Visual Studio 2005\Projects\WindowsApplication1\WindowsApplication1\Form1.cs 62 38 WindowsApplication1
help me, thank you verry mutch.

Is there encode.Image somewhere in your code?
The pieces you have shown are insufficient to diagnose.

Hi
I have a problem and maybe someone of you can help me :`|
I send a query to a SQL Server 2005
SingeltonConnection singletonCon = SingeltonConnection.GetInstance();
SqlConnection sqlCon = singletonCon.SqlConnection;
sqlstmt = "Select * From dbo.Team FOR XML RAW, ELEMENTS";
SqlCommand cmd = new SqlCommand(sqlstmt, sqlCon);
normaly i do it this was (with normal select * from dbo.Team querys)
cmd.ExecuteNonQuery();
while (reader.Read())
{
String tmp = reader[1].ToString();
...
}
but now i get an error (Index was outside the bounds of the array. )
SqlXml xml = reader.GetSqlXml(0); reader doesnt solve
So what is the return Type of my Query and how can i work with it?
thanks for your help

you have an index out of bounds error, whats that got to do with return type of query?
If only MySelf.Visible was more than just a getter...
|
|
|
|
|
hm i dont know how to handle the return of the query
i dont know how i get my XML data ... and normally the result should be in reader[1] or ???
|
|
|
|
|
this is the code i would use to write an xml document, you choose if you want to use it or not
SqlConnection conn = new SqlConnection("ConnectionString");
connection.open();
string query = "Select * from table";
SqlCommand cmd = new SqlCommand(query, conn);
SqlDataReader sdr = cmd.ExecuteReader();
DataTable dt = new DataTable("tablename");
dt.Load(sdr);
dt.WriteXml("outputFilePath");
oops, dont forget to close the connection

the FOR XML option returns the data in one, zero-indexed, column. reader[1] accesses a column that would not exists. reader[0], however, would refer to the xml data returned in the query.
Also, as a personal nit to pick. reader[0] will contain an object based on the type. While calling ToString is effective, it is not correct. (string)reader[0] and reader.GetString(0) would be more correct.
Need custom software developed? I do C# development and consulting all over the United States.
If you don't ask questions the answers won't stand in your way.
Doing a job is like selecting a mule, you can't choose just the front half xor the back half so when you ask me to do a job don't expect me to do it half-assed.
|
|
|
|
|
okay
i tried string x = reader.getString(0); and get this error
Invalid attempt to read when no data is present.
my query is okay i tested it in SQL Management Studio ... so where did i made my mistake??
|
|
|
|
|
|
okay ...
i got a solution
XmlReader reader = cmd.ExecuteXmlReader();
while (reader.Read())
{
xmlString += reader.ReadInnerXml().ToString();
}

why would this make your kid happy?
A piece of paper with the tables on would be much better for them, that way they can take into school and use them to cheat
plus you should prob have an option to set what multiple they want to generate upto

I have developed a C# class library that is used to control network communication of two application. The class provides all the functions/methods necessary to initialize, control, implement communications. I would now like to make this class into a DLL or someother object so that communication code is compiled and maintained sperate of the two application.
Question? Is Putting the C# communication code into the DLL the right solution for the problem? If not what is the right solution.

We don't have your problem definition so we can't know that. However there is nothing inherently wrong with it. Designing libraries can introduce different problems like configuration or security.

hi friends..i want to group and ungroup graphic objects...am storing these objects in arraylist..so please help me.......
txs in advance...
|
|
|
|
|
hmmm... well if you need them to stay in your array then maybe you need to add a 'group id' property to your graphics object
i would suggest a groupObject that contains a collection of graphics objects;
Then you have a collection of groups rather than directly collecting graphics objects.
Just one approach to think about

Hello ,
i find this code in C#
public static Image GetImageFromBase64String(string str, bool makeTransparent) <br />
{<br />
return GetImageFromBytes(Convert.FromBase64String(str), makeTransparent);<br />
}<br />
<br />
private System.Windows.Forms.PictureBox pictImage;<br />
pictImage.Image =GetImageFromBase64String(txtinput);<br />
in asp they aren't a method Image?
public static Image GetImageFromBase64String(string str, bool makeTransparent) <br />
{<br />
return GetImageFromBytes(Convert.FromBase64String(str), makeTransparent);<br />
}<br />
<br />
private System.Web.UI.WebControls.Image pictImage;<br />
pictImage.??? = GetImageFromBase64String(txtinput);
help me to get this picture, thank you verry mutch.

I think you are getting confused between PictureBox control and image itself. Picturebox is a control and you can assign any image to it in Windows forms. where as in asp.net Image is image itself. You need to specify either the url of the image or you can write the image to Response.Outputstream to display it on web page. You can't
set the Image in web application as you can set it in windows app.
In short you need to save the image to temp folder and set the ImageUrl property
OR
Write the image to Response's Outputstream as byte.

i have a server and client networked application , each time i test them , gives me an error "Unable to read data from the transport connection: The I/O operation has been aborted because of either a thread exit or an application request.
"
Here is the code for the client , knowing that the server doesn't disconnect the current client , the server still see the client as connected
the client code as follows :
<br />
<br />
<br />
<br />
<br />
<br />
void RunClient()<br />
{<br />
try<br />
{<br />
IPAddress ip = IPAddress.Parse("127.0.0.1");<br />
<br />
int port = 5079;<br />
<br />
IPEndPoint ipendpoint = new IPEndPoint(ip, 5079);<br />
<br />
client = new TcpClient();<br />
<br />
client.Connect(ipendpoint);<br />
<br />
Console.WriteLine("The Client has been Connected Successfully");<br />
<br />
lock (client.GetStream())<br />
{<br />
(client.GetStream()).BeginRead(data, 0, data.Length, new AsyncCallback(IASyncResultCallBack), client);<br />
}<br />
<br />
<br />
}<br />
catch (Exception s)<br />
{<br />
this.Invoke(new SetText(SetTextMethod), new object[] { s.Message });<br />
}<br />
}<br />
<br />
void IASyncResultCallBack(IAsyncResult ar)<br />
{<br />
try<br />
{<br />
TcpClient currentclient = ar.AsyncState as TcpClient;<br />
<br />
if (currentclient != null)<br />
{<br />
if (currentclient.GetStream().CanRead)<br />
{<br />
int count = (currentclient.GetStream()).EndRead(ar);<br />
<br />
if (count <= 0)<br />
{<br />
currentclient.Close();<br />
currentclient = null;<br />
GC.Collect();<br />
return;<br />
}<br />
<br />
ReadText(data, 0, data.Length);<br />
}<br />
}<br />
<br />
<br />
lock (currentclient.GetStream())<br />
{<br />
currentclient.GetStream().BeginRead(data, 0, data.Length, new AsyncCallback(IASyncResultCallBack), currentclient);<br />
}<br />
}<br />
catch (Exception s)<br />
{<br />
this.Invoke(new SetText(SetTextMethod), new object[] { s.Message });<br />
}<br />
}<br />
The error is in the following line of code
<br />
int count = (currentclient.GetStream()).EndRead(ar);<br />
<br /> br mode="hold" />when the compiler executes the following code it jumps to the next catch block giving the above error statement .
so what is wrong ????
