You can't. You obvioulsy misunderstood what a dll is. It's a seperate file. You can write a ton of code to fail gracefully, but the point of a dll is to be seperate. If you want it all in the exe, move the code into the main project.

Hello,
I have a console application the runs every few minutes and processes some files.
I am using the timer to do that.
However, I want the console window to disappear when my code is done processing all the files, then to reappear after the specific time has elapsed.
I dont know how to do this.
Thanks.

The simple way is to run it via a Scheduled Task instead.

Thanks PIEBALD. I think thats a great idea.

This p/invoke works
[DllImport("Kernel32.dll")]
public static extern int AllocConsole();
[DllImport("Kernel32.dll")]
public static extern int FreeConsole();
...
System.Threading.Thread.Sleep(3000);
FreeConsole();
System.Threading.Thread.Sleep(3000);
AllocConsole();

So, in the example - its going to allocate the console for 3 sec and then free it for 3 sec?
In my Main - I have the following:
<br />
Timer myTimer = new Timer();<br />
myTimer.Elapsed += new ElapsedEventHandler( DisplayTimeEvent );<br />
myTimer.Interval = 900000;<br />
myTimer.Start();<br />
while (Console.Read() != 'q')<br />
{<br />
;<br />
} <br />
How do I incorporate System.Threading.Thread.Sleep here. I'd have to get rid of the timer?
Thanks.

The Sleep(3000) in my example just demonstrated it -
in my case I was testing from a console app so the console
was already open when the sample code was hit.
I let it show for 3 seconds, hide it for three seconds,
then show it again.
You could use the same code in a GUI app but you'd need to
call AllocConsole() first to show the console window.
The Sleep() was to demonstrate that it works - you shouldn't be using
Sleep() - you have a timer 
AllocConsole() shows the console, FreeConsole() hides it.

Thanks, Great - Mark.
In my while loop, I called the AllocConsole and FreeConsole, but my console still stays.
Also, I was actually trying to synchronize it with the processing. So, its like -
1) After 15 seconds has elapsed, the console pops up - the program does the processing.
2) As soon as the processing completes - the console goes away.
3) Repeat.
Thanks for all your help.

Then what's the timer for?

Is that controlled by the timer? If I did the math
correctly, your timer is at 15 MINUTE intervals, not 15 seconds.

Thats right.
The reason is - I was testing it and didn't want to wait for 15 minutes every time, so I set it to 90000 which is 1.5 minute.
So, the problem is: the console just stays, while it should go away when the FreeConsole() is called.
Thanks.

hmm I'm not sure what's happening. Without your code it's tough to debug
All I know is I tested the code I posted in a C# console app.
If you make a C# console app that does the following, does it work?
[DllImport("Kernel32.dll")]
public static extern int AllocConsole();
[DllImport("Kernel32.dll")]
public static extern int FreeConsole();
static void Main(string[] args)
{
Console.WriteLine("Hi from the first console");
System.Threading.Thread.Sleep(3000);
FreeConsole();
System.Threading.Thread.Sleep(3000);
AllocConsole();
Console.WriteLine("Hi from the second console");
Console.WriteLine("\r\n\r\n");
Console.WriteLine("Press Enter to end...");
Console.ReadLine();
}
If that works, then what are you doing different in your code?

I did the following and it's working fine now.
[DllImport("Kernel32.dll")]public static extern int AllocConsole();<br />
[DllImport("Kernel32.dll")]public static extern int FreeConsole();<br />
static void Main(string[] args)<br />
{<br />
System.Timers.Timer myTimer = new System.Timers.Timer();<br />
myTimer.Elapsed += new ElapsedEventHandler( DisplayTimeEvent );<br />
myTimer.Interval = 90000;<br />
myTimer.Start();<br />
while (true)<br />
{ <br />
;<br />
}<br />
}<br />
public static void DisplayTimeEvent( object source, ElapsedEventArgs e )<br />
{<br />
AllocConsole();<br />
FreeConsole();<br />
}<br />
Before...I was trying to call them in the wrong place.
Thanks so much.

Any experience or ideas printing labels from Dot.net (C#) - what's the best way
Current project uses 2 column/5 row and 3 column/10 rows labels. TIA

Hi,
Both Crystal and Reporting Services can be used. Maybe it's a little bit easier with crystal (mainly creating the layout).
However, if you can use MS Word, it's even simpler with it using mail merge. In that case c# code creates the data and delivers it to Word and all of the layout is done using Word. This method is perhaps the easiest and as a bonus, the layout can be modified independently from the program.
Hope this helps,
Mika

Sounds like a plan to me especially if you don't see any downsides in current solution.

hy everyone!
i do have some problems with the process.start() methode.
i want to start the following command via the process.start()
"C:\Program Files\Acrobate\Reader 8.0\Reader\AcroRd32.exe" /h /t "C:\sourcedir\somefile.pdf" "printer001" (sure it's not the correct syntax here, but it's readable this way)
when i try to start this code in command line then it works fine, but when i add it to the process.start() methode, it either does nothing or it throws an exception "there is/are invalid path/s"
I added full access to the sourcedir, so access problems shouldn't be the reason.
when i just try to start acrobate as parameter (so e.g.
System.Diagnostics.Process.Start("\"C:\\Program Files\\Acrobate\\Reader 8.0\\AcroRd32.exe\"");
, it works and it start acrobate as a process. when i just add the file including the dirinfo e.g.
System.Diagnostics.Process.Start("\"C:\\sourcedir\\somefile.pdf\"");
, it accepts it as well. but it does not work using the whole string above.
i also tried to use the startinfo object with all it's parameters, but it didn't work neither.
does anyone of you have an idea? I don't think it's a problem because of access rules, because why would the acrobate start if there were some?? 
thanks!
stephan.

Hi,
What if you try:
System.Diagnostics.Process.Start("C:\\Program Files\\Acrobate\\Reader 8.0\\AcroRd32.exe", "\"C:\\sourcedir\\somefile.pdf\"");
Mika
|
|
|
|
|
is there a difference in mering it to one string or to seperate it with a comma??
and is there a chance to get it start with the parameters and the printer this way?

Just wondering is there a typo. Should there be folder Reader after Reader 8.0? Take a look at the paths you posted
C:\Program Files\Acrobate\Reader 8.0\Reader\AcroRd32.exe
C:\\Program Files\\Acrobate\\Reader 8.0\\AcroRd32.exe
|
|
|
|
|
yeap, this is a typo, sorry.
the correct path is C:\\Program Files\\Acrobate\\Reader 8.0\\AcroRd32.exe in every example.

|

No problem That solved the problem?
