Everything seems ok.
Could you pls send the SendCommandSynchronous method
|
|
|
|
|
thanks again for reply..
here is the method:
private MAIL_ERROR SendCommandSynchronous(string cmd, out string response, bool bMultiLineResponse)
{
// Remove any data that was left over on the buffer
string deadData = _conn.Receive();
_conn.Send(cmd);
response = WaitForResponse(bMultiLineResponse);
return MAIL_ERROR.ERROR_NONE;
}
private string WaitForResponse(bool bMultiLine)
{
int timeout = 5000; // wait 10 seconds for response
int waitedTime = 0;
string strRet = "";
while (waitedTime < timeout)
{
System.Threading.Thread.Sleep(_TimeOut);
strRet += _conn.Receive();
if (CommandComplete(strRet, bMultiLine) == true)
{
return strRet;
}
waitedTime += _TimeOut;
}
return strRet;
}

Could you try
private string GetResponse()
{
string strPrev = null;
string strCurrent = null;
string strMessage = null;
NetworkStream ns = default(NetworkStream);
ns = client.GetStream;
while (true)
{
byte[] buffer = new byte[1];
ns.Read(buffer, 0, buffer.Length);
strCurrent = System.Text.Encoding.GetEncoding(1254).GetString(buffer);
strMessage = strMessage + strCurrent;
if (strCurrent == @"\r" && strPrev == @"\n")
{
break;
}
strPrev = strCurrent;
}
return strMessage;
}
private void SendMessage(string str)
{
str = str + "\r\n";
byte[] buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(str);
NetworkStream ns = client.GetStream;
ns.Write(buffer, 0, buffer.Length);
}

Hi everybody
I have a panel in my form, I used backgraound image for my panel.
In the Panel OnPaint event body, I draw ellipse with various position and dimension on each times.
So I use a timer, On the OnTimer event I Refresh panel for clearing previous ellipse and draw new ellipse with new parameters.
when form refreshed a bit jumping occurred in my background image, since I use mentioned operation every second, these jumping annoy the user.
I want to know how can disappear these jumping, Maybe for clearing prior ellipse use another method instead refresh or invalidate.
Best Regards,
Reza Shojaee

You can turn on double buffering.
this.SetStyle(
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.DoubleBuffer,true);

Please I would like your help in the following questions,(Please supply code example.)
:
1. How can I make a program’s able to link with its database independent of location?
There is a program I am trying to create. It works fine only if the database is placed in a particular location. I would like the program to be such that a user can install the program in any location and my program can look for and locate the database.
In a multi-tier network application, let us assume the following conditions exist:
• The front –end is in VB.NET/ C# .NET. (I am at home with any of them so you can write the code in any of these languages) The back-end is an oracle database.
2. How can I link the two? The front-end is not in the same computer as the database.
3. How can I make my apps able to read/ write real-time data?
Thank you .

Depends on the DB type. If it's a file, like an MDB, you need to let the user browse to it, and build a connection string to that file.

Well, it depends. Are they on the same network ? Then you just need a network path. If not, then it will need to be on the internet, which means it will be visible on the same URL to everyone. So, you need to let the user specify a network path, and build a connection string from it, I expect.
ihe wrote: 3. How can I make my apps able to read/ write real-time data?
I'm not sure what you mean. If your DB is over a network, that will slow down the DB. Your best bet is to cache data and have another thread periodically storing it to the DB. Minimising the number of DB calls will make it faster.

You need to specify the server location in your connection string, so, in practical terms searching for your database is not feasible - you would need to connect to every instance of every server and see if your database was on that server. There would eb all sorts of security issues, and if the database existed on multiple servers which would you use.

See answer 1, using the conneciton string. A good source of info is www.connectionstrings.com[^]

Not sure what you mean. You write to and read from a database in real time.

Thanks. www.connectionstrings.com is very good.
Real time:
Let us assume that there is an on-going continuous process. I want to be able to monitor it, without being present. I want to design a program that would write the start time / end time to a database without a user clicking a button. The program would monitor and detect when the process is ongoing.
If there is any variable associated with this process, the program would write these values in the database as well.
The program should write the values as the process is occurring. It should not involve any human interference as this would cause a loss in time (lag time) for the human to click the control (for saving).
The program should monitor, detect and write the event as fast as the process occurs. A type of survellience.
Please explain how I would go ahead in this program

Hi
Is there any way in which i can convert a xml file to a word document..can u please demonstrate with a small example??
|
|
|
|
|
You can use word interop to write xml file's content to word document. If you google 'how to create document with word interop' you'll find tons of examples.
|
|
|
|
|
Now i am already using the interop object.I just want to know if this can be done in any other way.

What I am wanting to do is something along these lines but I can not figure out how to do it, if it is at all possible...
What I want to do is place several shortcuts directly into a folder onto the desktop and place a icon onto that folder.
(easy enough)
Now for the problem arises. I am now needing to make the folder on the desktop with the icon act like a autorun. That is to say if the user double clicks the folder for the folder to automatically open the default shortcut instead of opening the folder displaying all the shortcuts.
We want the shortcuts to be availiable but only if they rightclick the folder and say explore.
Any Ideas?
Both in how to do this manually, then in how to do this in code. But If I could figure out the manual part I probably could figure out the code.

This sounds messy and complicated for the end user ( because you want a folder to not act like a folder ).

As you want to alter the default behaviour of a folder, thats going to be very tricky.
One possible hackaround could be, create a new file extension and alter the behaviours. That way you could have a default action of 'open program', but also had a secondary action to open a folder.
The only other possible thought would be to see how you can create those 'special' windows folders (control panel, .net assembly etc) if you could work that out...but that would be a nightmare of registry hacks, and not something I would like to see a program 'do' if I was a user.

I agree it is not something I would normally be wanting to do but it is being required of me to find a solution like this. It sort of works like the mac application package folder from the research of what their requesting of me.

Ok, silly question...excuse me while I try to understand exactly how the stack works:
Example:
int a = 123;
int b = 456;
int c = b;
If the stack was horizontal, with first in on the right, you have: c = 456 | b = 456 | a = 123
Now set:
b = 789;
You have: c = 456 | b = 789 | a = 123
Ok, fine, no problem...but how did b get changed if you have to 'pop' c off to get to b?

Locals in C# do not get on the stack in the MSIL phase. They will, of course, after the JIT compiler has done its job, but that's a different kind of stack.
Both are easy to check:
- for the MSIL way, open the assembly (in the meaning of ".NET assembly" which is a file) with the Reflector and set it to IL view
- for the native way, put a breakpoint somewhere and debug, when you hit the breakpoint open the disassembly window
|
|
|
|
|
Some more info:
For locals, MSIL has stloc and ldloc in various forms, they operate on "local slots" (and the stack of course, to get their operands from, but they don't put their data there)
(talking to myself, yay)

I'm assuming by stack you mean the stack that the program stores it's local variables in (not one you've produced yourself using the Stack class.
When the variables are stored, the stack is just a way of looking at the specific area of memory. Unlike the .Net Stack class, you don't have to pop things off to access them. The same region of memory could also be treated as a list, a queue, or anything else. The program stores the address of each variable, and then accesses them directly, so you can access b without touching c. Then, when the function finishes, all the variables are popped off of the stack.
This is one of several ways of storing local variables in a function, and is very low level stuff. You shouldn't have to worry too much about it.
Disclaimer: The .Net Framework may do something different to the stack, but the principle should be the same.
