Sounds like the initial value of a control with "minimum and maximum" values is being exceeded.

Hello,
I was wondering, if there is any way to create out of office rules (Reply-With Templates, forwardings... http://office.microsoft.com/en-us/outlook-help/send-out-of-office-notices-automatically-with-an-exchange-account-HP001232830.aspx#BM2[^]) in Exchange 2010 using c#? (Preferably EWS)
I know that this can be done in Exchange 2003 using MAPI, but I was unable to find any Information for Exchange2010...
Any suggestions?

Hi i have created one web application and in that i need to read the data from Mysql database and bind to gridview.
I have written Mysql query as follows
SELECT @row_number:=@row_number+1 AS row_number,Name FROM tablename, (SELECT @row_number:=0) AS r
After running in Mysql in database it will and work show the result.
But if take same query and execute through C# code below error is coming.
An exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll but was not handled in user code
Additional information: Fatal error encountered during command execution.
and i will get Break or continue pop up. If i give continue it will show Parameter '@row_number' must be defined.
even i defined like int @row_number = 0; but same error.
I need to achieve serial number as shown below
ex in database
slno name
10102 nama1
2123 name2
5203 name3
result
1 nama1
2 name2
3 name3
how to achieve this. If anybody knows please reply me.
Thanks in advance.

There's an @-sign in there (declaring a user-variable), so .NET will assume you're declaring a parameter. There's no parameter in the collection with those names, hence the exception.
Easiest way out is to create a stored procedure. Wrap your SQL in there, call the sproc from .NET.

while I am sending SMS it give me Error Like "The Operation has time out " and I trace that error is in this line - "objStream = sResponse.GetResponse.GetResponseStream()"
Following is my Code
Dim sURL As String
Dim objReader As StreamReader
Dim objStream As Stream
Dim sResponse As WebRequest
sURL = " MyAPI"
sResponse = WebRequest.Create(sURL)
objStream = sResponse.GetResponse.GetResponseStream()
Can Any one help what is wrong I don't understand because first time it not give me that error while I am sending second time it give me that error
Help Me Please...
Thank You

What is that URL supposed to be because what you have in there is not a URL and that's probably why your getting the timeout.
|
|
|
|
|
Perhaps the OP obfuscated it for posting -- since this is about an SMS.
If it were not valid the second time, it would not have been valid the first time either -- and OP stated -- it worked the first time -- but not the second time.

I would advise you to examine very carefuly your use of the streams and the WebResponse -- also avoid trying to reuse them -- this is an inherently asynchronous process and trying to create an SMS bulk texting application is not what those classes are intended to do -- it is one thing to use them to mimic browser fetches, but quite another to use them statically for multiple texts.
At the very least, close them and get them each time -- the Response -- are you reading to the end and closing the response?

does anyone know if it is possible to sample an area of my screen,
eg every 5 second into my memory for it to be processed?
|
|
|
|

You're going to have to explain that in quite a bit more detail before you get any kind of useful answer.
"Sample"? Define that exactly and what you mean by "process".
|

hi,
sorry for being ambiguous.
what i meant was is it possible to sample the image being displayed on my monitor and process it.
eg if my monitor top left pixel is red then a message box will appear saying its red.
|
|
|
|
|
Possible, yes. It's quite easy to get a copy of any part of the screen as a Bitmap. Just use Graphics.CopyFromScreen[^].
|
|
|
|
|
Yes, it is.
You'll never get very far if all you do is follow instructions.

There are two ways of doing this through a single process called a SnapShot.
1. You can capture your entire display area, or
2. by defining a rectangular area on the display area called the ROI (Region Of Interest)
There are lots of code samples out there that covers both scenarios. Use Google to search for "How to take a snapshot of my display" or "How to capture an area of my screen".
You can then save the memory stream (the captured information will be stored in a memory stream) in a few formats - JPG, TIFF, PNG and BMP.

Hi,
I have a program created by me which I've been using for some time now. It's a tool for android and ios. I want to make it so if there is a connected android or ios device on my computer my program will automatically detect it but unfortunately where to start. I've been searching all over Google and found nothing of use. For example when the device is connected my label1 text will say something along the lines of "ios device connected"

AFAIK, there's no high-level library that can identify these. You could try and see if you can find them using WMI

Presumably your wrote this tool. And presumably it already does something with both devices.
So why can't you just find a do nothing API for each device, such as a query for version number, and put that in a thread that polls every X seconds. If it gets a result then the device is there. If no result then the device isn't.
|
|
|
|
|
if you want the android to be connected why don't you just use adb cmd command on your program to make it easier?
to check if the device is connect "adb devices"
or you can try to search a dll "androidlib"?
everything is in the documentary how to use it.

Hi,
while reading buffer from TCP/IP continuously after some time i am getting this error.. could you please anyone help me to resolve it....
1.
An unhandled exception of type 'System.Net.Sockets.SocketException' occurred in System.dll
Additional information: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
2.
An unhandled exception of type 'System.IO.IOException' occurred in System.dll
Additional information: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
Regards,
Ganesh

Without seeing the relevant code it's impossible to tell you anything useful.

Greetings.
I would like to see your code, too but -- I can offer you some help anyway.
Always use try/catch for network communications and db access and ignore anyone that tells you not to -- unless it is your boss, but even then -- you should use it. I am saying this -- not to chastise you or puff myself up -- I am saying it because if you do you will not only learn how to fix this yourself -- you will learn to write code that can handle issues and also it will perform better. Generally, I will wrap most all of a function in try/catch if it involves communications or database access. You do not need it everywhere, just in key areas that warrant it.
If you ignore it altogether -- your application will halt because you did not use try/catch-- not good for anyone and not good for you. If you use try/catch -- at least you know that an error occurred and at least the code can exit gracefully instead of spitting out that page that tells your users that your code just died on them.
You said -- continuously -- but, the exception seems to be telling a different story. I suspect that your buffer read is either missing data that is in the buffer, or you are not servicing it often enough or -- your buffer is too small to begin with. TCP has some built-in defense against many errors, but it cannot force you to service the socket properly, so -- it is the buffer, the socket properties or your read code. How large is the expected data?
Mostly, guessing buffer sizes is a bad idea -- either you get one too small or you waste resources by making it too large. This is not a career where guessing is a good strategy and asynchronous communications demands that we code properly and not make assumptions.
