Hi,
According to the documentation, each BeginXxx needs a corresponding EndXxx, and typically that can be handled by the callback method.
I can't tell you what exactly is wrong in your code, however it is my impression your code is too complex and not sufficiently safe. I would code this more defensively, and avoid all the global variables your class seems to hold (receiveDataBuffer, bytesReceived, messageLengthReceived).
These are things I would do differently:
1.
I would create a little class holding clientSocket, the receive data buffer, an index into it;
then create two instances (one for length, one for data) of it for each length+data communication, and pass them as the last parameter to the BeginReceive calls (and retrieve it from the EndReceive calls).
2.
I would completely split the WaitForData() method into a WaitForLength method and a WaitForData method.
And I would completely split the RecieveComplete() method into a ReceivedLength method and a ReceivedData method.
(2) makes messageLengthReceived redundant.
(1) avoids the risk of receiveDataBuffer and bytesReceived to contain data belonging to another ongoing communication.
I am not saying the problem will be solved by doing this, I do claim the code would be more robust and easier to read, and either the problem is gone, or you'll have a better chance of locating the problem.
FWIW: I'm puzzled by AsyncClient.BUFFER_SIZE, it appears only once in the code shown; is it the size required to hold the length part only?
Hope this helps.

Hello,
I need to convert the doc file into an image file.
I do not want to use the print functionality (Microsoft.office.interop) as the print out remains opened on the desktop
OR
I should say how can I close the print out of the file so that client do not come to know about that?
Thanks & Regards,
Sheetal Rawat

I don't think there's anything built in to do that, not even in the interop stuff. Your best bet. I'd think, is in taking a screenshot. Or printing to PDF.

Please help me regarding this>>
I have a declaration of method like this
public ViewMethod([CreateClass] IInterfaceController controller)
{
this._controller = controller;
}
What does [CreateClass] mean/do here?

I would imagine if you don't already have a class Controller that implements IInterfaceController then that's what you need to create.

It looks like you're using a Dependency Injection framework such as Unity. Am I right? If so, the documentation should tell you.

Take some time to actually learn, don't just copy and paste.
only two letters away from being an asset

It's a custom attribute - you'll have to look for the class CreateClassAttribute in your source.

 I never considered that as I've never used (or needed to) an attribute on a parameter, I didn't even know you could! Something new learned today

Unless I misunderstand the error is correct:
The Key <big>ConnectionString</big> does not exist in the app setting configuration section
as in
<add key="<big>Main.ConnectionString</big>" value="...
the key is "Main.ConnectionString"
Hope this give you the answer you need!

First of all thankz for your reply
Sorry keefb
it is my written mistake in question .......In project I am using same key .........now I corrected my question ...please check it again ......In app.config the key is ConnectionString .........and I also use ConnectionString (Same variable) in Code file ............Now please check it and can you tell me where is problem ....
why error occurs that I mentioned in first post
|
|
|
|

Can you post the code that gets the connection string?
|
|
|
|
|
Here is code
public clsGeneric()
{
_mainConnection = new SqlConnection();
AppSettingsReader _configReader = new AppSettingsReader();
_mainConnection.ConnectionString = _configReader.GetValue("ConnectionString ", typeof(string)).ToString();
}
When I run project from visual studion it run fine......but when I create installer and install application then run from installed exe then error occurs
|
|
|
|
|
Is there an app.config or yourapplicationname.exe.config in the installation folder?
|
|
|
|
|
app.Config.
I added this file in application folder of setup project
|
|
|
|
|
There is the problem. Say your application builds to an exe called Foo.exe, it expects the app config file to be named Foo.exe.config, not app.config. So you can't just copy the app.config into the installer directly.
Make sure the Installer project has "Primary output from your project name here (Active)" in it. As long as the app.config exists in the source project it should be installed with the correct name.
Also Greg Chelstowski's post is correct, you should consider using a ConnectionString element in your app.config rather than adding the connection string as an app setting.

Hi keefb
very Thankz
Problem is fix
|
|
|
|
|
Why do you not use ConfigurationManager.AppSettings["ConnectionString"].Value.ToString() instead?
Moreover, why do you store your connection string as an appsetting, and not as connectionString in your app.config?
var question = (_2b || !(_2b));

|
|
Thankz Greg Chelstowski
I change the connection string according to ur post
