Hi All,
I have an application that tries to print a PDF File to a network printer from the WebBrowser control. I am able to print the report if I just run the exe directly. But when I tried to start the application from a service as a new process then it could not find the network printers. Is there any secruity permissions to be applied when starting a new process from the service? Or what could be of the cause and its possible solutions?
Kindly help me.. I am just struggling a lot in this!!
Thanks,
Sivakumar R

Your service runs under the local account, which means that it won't be able to use network resources.
Start the service under a given user account instead. And use a user account that has the rights to do network printing.

Hi,
You are right. The service is currently running as a local system account. But I have one more limitation here. My application is a Desktop Application, I am starting this through a Service to grant/deny some rights to my application. So the service needs to be on a Local System Account to enable this option.
I tried configure the service to work with the network user. But unfortunatly, my application is not displaying the GUI. I gone through the following article : http://www.codeproject.com/install/...vicedesktop.asp
to try to enable the service to interact with the service. But it does not seems to be working.
Here is what I was trying to do..
- I tried to login as a network user
- I change the Logon properties of the service to work with a specified account.
Is it possible to make the service to interact with the desktop even if we set it not as a local system account?
Thanks a lot for your suggestions!!
Regards,
Sivakumar R

Hello.
I had exactly the same problem a while ago but I couldn't find a solution, so gave up 
In the end, I autostarted the app instead of running it as a service.
And configured auto-login for the user.
Not the best solution, but it worked (kind of)...
Anyway, the program is started when windows i started, which was the main demand.

Hi,
Thanks for the reply.
I had to make my application to toggle between the OS and Application. When the user login as an administrator in my app and shutdown, it should restart into the OS. When they restart from the OS, then it should go to the applicaiton mode. So I had to go for the service to decide whether to start the application of just go to the OS. Everything works well and running except that I could not access the network printer. It works well with the local printer.
I am just trying to get if we set any security attributes before starting the service / my process, is there anyway I can access the network printer.
I sincerely thanks for your valuable suggestions!!
Regards,
Sivakumar R

I am trying to simulate a user clicking through a series of tasks in IE. Some of those tasks require a user to click on dialog boxes, for example “Deleting this item may have harmful consequences”, or clicking through a “Save As” sequence of dialogs. I can successfully click on the buttons using windows messaging BM_CLICK. The only problem is I have to wait for 1 to 2 seconds after the dialog box is instantiated for the click to happen reliably. But just waiting for a couple of seconds is not an option in this situation. I have tried a number of things to try to deterministically figure out when it is a proper time to be able to click, like setting the dialog to the foreground, set it as the active window, I have trying using BM_LEFTDOWN, and BM_LEFTUP instead of click, trying to send a null message with a callback to make sure it is in a state to process messages, all to no avail.
I think that there is some process that must be happening in the first second or two, that I am unaware of. I would like to be able to hook into the button and listen to all the messages it is receiving or sending from the very instant that it is instantiated and maybe wait for a certain set of messages to happen before I continue the simulation.
Is there a relatively easy way of hooking into another windows messaging queue and seeing ALL the messages that it is sending or receiving (similar to spy).

If you want to wait until the application is ready to accept input check out the WaitForInputIdle[^] function.

1 - try to put something meaningful in the subject line, so people who can help are attracted to it
2 - if you have an error, posting the error is great, but posting the code as well, is even better.
3 - Your form is called Form1, are you using C++/CLI ?

How do I specify compiler options in the DDK build environments?
I trying to build with /EHsc to enable c++ exceptions...
Thanks for any help.
|
|
|
|

Got it:
"USER_C_FLAGS = /EHsc"
in the sources file.

Be very careful if you are recompiling drivers in the DDK with that flag. They may not be (in fact, probably are NOT) written to handle exceptions. If you're just compiling your own user-mode app from the DDK environment, no worries.

Thanks, I'll have to look at that since it's part of a printer driver

Hi
I injected a DLL into another process. So far, it works fine.
Now I'd like to send messages to the DLL ... I'tried PostMessage but it always returns ERROR_INVALID_THREAD_ID
The code looks like this:
CreateRemoteThread(hProc, NULL, NULL, (LPTHREAD_START_ROUTINE)LoadLibAddy, (LPVOID)RemoteString, NULL, &ThreadId);<br />
<br />
while(!PostThreadMessage(ThreadId, WM_MYMSG, NULL, NULL))<br />
{<br />
if(GetLastError() == ERROR_INVALID_THREAD_ID)<br />
break;<br />
else Sleep(500);<br />
}
and the DLL loops until a message is received (so it loops infinitivly atm )
while(1)<br />
{<br />
if(GetMessage(&msg, NULL, 0, 0))<br />
break;<br />
}
thanks in advance !

Do any of these potential problems apply?
"GetLastError returns ERROR_INVALID_THREAD_ID if idThread is not a valid thread identifier, or if the thread specified by idThread does not have a message queue."
"Windows 2000/XP: This thread must either belong to the same desktop as the calling thread or to a process with the same locally unique identifier (LUID). Otherwise, the function fails and returns ERROR_INVALID_THREAD_ID."
"Go that way, really fast. If something gets in your way, turn."

Did you find that information hidden in the documentation?

Extremely well hidden!
I'm pretty sure I find 2% of answers in my code and 97% hidden in the documentation.
The other 1% I pull out of my
"Go that way, really fast. If something gets in your way, turn."

I had to do this with MMC a few years ago. I used custom messages WM_APP+n where n > 50 and posted them to the main window. My 'injected' Dll, actually a Console plugin installed an application wide Message Hook and filtered out the things it was interested in. Not an elegant solution I know and I hope you don't have to stoop to it. At least you are trying to recieve messages on your own thread not relying on MS to give your control some runtime.;)
