Sorry for my poor english, thanks for your anwers.

You can use a byte array to save any binary files in memory.
If you are dealing with an System.Drawing.Image object I suggest you serialize it into a memory stream,get memory stream buffer and let the memory stream go.
<br />
byte[] myImage;<br />
using(var ms=new MemoryStream())<br />
{<br />
var bf=new BinaryFormatter();<br />
bf.Serialize(ms,theImage);<br />
myImage=ms.GetBuffer();<br />
ms.Close();<br />
}<br />
You can use a BinaryFormatter again to deserialize myImage into an Image object.
<br />
Image theImage;<br />
using(var ms=new MemoryStream(myImage))<br />
{<br />
var bf=new BinaryFormatter();<br />
theImage=(Image)bf.Deserialize(ms);<br />
ms.Close();<br />
}<br />
Note : System.Draw.Image is serializable so we can serialize and deserialize it .To use the same method on nonserializable objects there should be a way to write content of the image into a memory stream.

hey guys...
I m developing an windows based application for an organisation using c#. I used an gridview to display table data. For updation at runtime,I used "gridview.edit" method. Now what I want to do is, when I update secont and third cell of a row , the data of fourth cell should also get updated.
Please help me..
|

|
|
if you are adding data from a database.Table then use
you can use DataGrideView.Datasource=datatable
|
|

Well you need to be at least accurate in your descriptions, I'm betting you are using a DataGridView rather than a GridView.
Without some accurate, relevant and detailed information about your specific problem we cannot help you, your question is too vague.

I'm control threads by a monitor and I want to assign a priority number to each thread
for example:
thread1 with priority number:2
thread2 with priority number:1
thread3 with priority number:4
thread4 with priority number:3
I want to execute my threads in this sequence:
thread2
thread1
thread4
thread3

Be generous, give us some detail of what the problem is, it flactuates very much is a little vague.
Have you stepped through your form activation code to see what possible causes there are.

Where are you storing your username and password? You storing it in your application or in a Database? These details would help.
Excellence is doing ordinary things extraordinarily well.

Hi,
I have an email application and when checking mails I use a new thread (so it doesnt stuck the whole program while downloading data).
the problem is that this method (runned by the new thread) fires some events, and some of that events have observer methods that modify a textbox (txtLog).. and it throws this exception InvalidOperationException..
How do i resolve this?
The weird thing is that some observer methods modify a status bar and there the exception isnt thrown

Hi,
you need to invoke a delegate, have a look at the SetText method of this article[^] (SerialPort.DataReceived event also runs on a separate thread).

Thanks,
why does cross threading work with a label on a status and not on a textbox?

Hi,
I don't know, I am not convinced your observation is correct: Controls are NOT thread-safe and since they typically are all interconnected in some way, you should not touch any Control from a thread other than the main thrad (aka GUI thread). Sine .NET 2.0, when you do, an InvalidOperationException is to be expected.

May I use a lock(new Object()) for making it thread-safe instead of the InvokeRequired thing?
