Try to use the sample of SerialPort Class from MSDN.

The manufacturer of the reader will almost certainly be able to supply you with an SDK. Check their website or ask via e-mail

string lookFor; // used to store the restaurant name we are looking for
BOOL bFound;
//Take the 1st element in the linked list
while ( ! ListEmpty(l) )
{
lookFor = l->elem->restaurant; // Storing r. name for the current list element...
bFound = FALSE;
tmp = q->front; // Get the first element in the queue
while( ( ! QueueEmpty(q) ) && ( ! bFound ) )
{
cout << tmp->item << tmp->cuisine << tmp->mode << endl;
if ( ! strcmp(tmp->restaurant, lookFor) )
{
bFound = TRUE; // found what we were looking for!
}
else
tmp = tmp->next; // still not found, search further in the queue
}
if ( bFound ) // It was found
{
//Do what you please with the info in *tmp*
//it is the coresponding to the current list item
}

You keep asking the same thing, and at least 2 of us have asked for further clarification a couple of threads down from your original posts. I suggest that you re-read these comments carefully, and rephrase your question to address the points people have raised.

Ask in the correct forum.

Who could possibly determine what you want based on what you posted?
Try googling "C# windows form animation", and see what you come up with.

Hi.
i'm trying to debug some problem on a code which i didnt wrote.
what happends is that when i execute a c# based process (lets call him mfProcess), one of my log file is locked by it (lets call him mfLog.log)
the file is unlocked before i execute mfProcess.
by debugging ,i stoped at the first line of code of mfProcess, but the file has been already locked, which means something happends from the time i run the exection command (the file is free) and the first line of the mfProcess code(the file is locked.
have any ideas?
Thanks.

Is it a .Net DLL?

yes, those are .net dlls.

Then it's not a DLL initialization problem. It's more likely that you're using the class incorrectly, and that the assembly is written poorly.
When you add a reference to the assembly in your project, you can see discover the API by right clicking on the reference and selecting "view in object browser". After looking around a bit in there, you may be able to find out what you're doing wrong.
Beyond that, there's no way we can help you resolve the problem.

Hi,
I am using prnadmin.dll to add a shared printer on to a remote machine. The printer gets added but it is not shared.
Do you see anything wrong with this code please?
printer and printMaster are dedclared as PRNADMINLib.Printer and PRNADMINLib.PrintMaster respectively.
printer.ServerName = "\\\\remoteMachineName";
printer.Network = 1;
printer.ShareName = "printerName";
printer.PrinterName = "printerName";
printer.Shared = 1;
printMaster.PrinterAdd(printer);
Any thoughts please?
Thanks

From your code it does not look like you are checking for errors. Maybe, or just perhaps, that will tell you what is going on.

Hi,
I do have error trapping in my project for this.
No error is reported because the printer does get added but not as shared.
Any other thoughts?
Thanks

Sorry, nope. Maybe permission related?

Hi.
I'm building an application in winform environment that have a Tabcontrol in it.
That tabcontrol should have multiple lines in it.This can be done by setting the multiline property in the control.
But what i have trouble in is ordering the tabpaged in the control in a custom order.
for example , i want the first row to have 4 tabpages, second row 10 tabpages and so on....
can i accomplish that task without altering the tabpages width that causes
the tabpages to slide off to the next row?
thanks

how can i keep a connection open while repeat declaring sqlcommands using it.
con.open
while condition = true
{
sqlcom = new sqlcommand("select statement", con)
//con.close(); //ref below
sqlcom.dispose();
}
this while block will throw an error:the connection is already in use. so i have to close it like the commented block. i dont want to keep closing and opening the connection while it loops(more than a 1000 times). how best can i solve this.
My idea was to keep the connection open but i dont know know how to do it without getting the error.

If you use a data reader to read the result from the command, the connection is in use until you have closed the data reader. If you want to reuse the connection in a loop, you have to read the result and close the data reader inside the loop.
Despite everything, the person most likely to be fooling you next is yourself.

|
|
|
yes im using a data reader
do u mean i have to do like this
while dtr.read()
{
do something
dtr.close
}
|
|
|
|
|
Yes, with the small modification that you close the data reader outside the loop that is using it.
As long as the data reader is open, you can't reuse the connection.

You don't have to worry about that. In .NET connection pooling is turned on by default. Even if you call the Close() method, the runtime leaves it open just in case it will need to be used again.
|
|
|
|
|
my problem is i dont want to do a lot of connections to the database. i just want to open the connection once and then close it once im done with everything
