Is this running via ASP.NET? Or some other user with limited permissions? Or perhaps not on the Local Computer Zone?
|
|
|
|
|
both applications running on the local machine under a administrator account
|
|
|
|
|
It seems you are running it as a service?
Try running it without it perhaps. Not sure I can help any more 
Try Googling for something similar.

Now I'm working on VS.NET 2008(professional edition), but for some reason, i need to use VS.NET 2005. So, i'm going to install VS 2005.
I need to know
whether it can cause any serious problem by having vs2005 and vs2008 on the same machine?
thank
^^

Hi,
I use VS 2003, 2005 and 2008 on the same machine and I have never encountered any issues with it.
You may have VS 2005 and 2008 on the same machine, provided the machine is hardware compatible for the use.
Hope this helps.

I have both the versions on my machine. But just to let you know that in Visual Studio 2008, you can set the target framework to .Net 2.0 which is same as Visual Studio 2005 framework.

Just when I thought all the coding is done, i've hit a brick wall .. It's CP to the rescue 
I have an NT Service ("Windows Service") which does some processing based on a configuration file. I can install and uninstall this NT service using installutil without any problem.
However, I need to be able to run multiple instances of the same NT Service each with various param.
E.g.
service1.exe /config1.xml
service1.exe /config2.xml
service1.exe /config3.xml
I have tried modifying the install-script and pass param:
e.g. installutil /i "service1.exe /config1.xml"
This installs, but when I look at the actual registry value under HKLM\System\CurrentControlSet\Services\Service1, the "ImagePath" key does not contain the additional arg I passed at install-time.
Then I manually modified the registry-key to include the additional arg, but I still cannot run subsequent installutil. It fails with "The specified service already exists" error.
How can I install multiple process instances of this Windows NT Service ? (Windows does runs multiple instances of "svchost.exe" without any problem)
Due to some constraints I cannot a) consolidate the logic and run as single process multiple threads or b) consolidate the logic and run as single process multiple app-domains or c) create multiple copies of the binaries in N different locations.
I look forward to your responses.

You can have multiple instances but you need to create them as different named services. You have to give them different names.
When starting a service, the Service Control Manager looks at the ImagePath to determine if the process that runs this service is already running. If it is but the process specifies WIN32_OWN_PROCESS in the Type value (either for the process already running or the one to be started) it fails. When performing the check, the whole command line, not just the EXE name, is used.
SvcHost uses the -k parameter for this purpose. This parameter doesn't do anything. It's just there to make the SCM instruct the right instance of SvcHost to start this service. SvcHost itself is a generic host process - it doesn't do anything itself, it just loads the DLL specified under the service's Parameters key. Microsoft have not documented the interface that a DLL must implement to be loaded by SvcHost - it's intended for their own use only.

Put a Console.ReadKey() in there. This will keep the window open until someone presses a key.

Hi All,
How can i know from the keyboard scan code what is the real key ?
I using KBDLLHOOKSTRUCT Structure in my keyboard hook to get the pressed keyboard information - But i still don't understand how can i know what the meaning of the key that was pressed even if i know the scanCode of the pressed key.
I don't want to use "switch..case" to check for each option pair So ... i looking some .net Framework class ( or win32 function ) that can find the value of the scanCode of the pressed key.
Beside this - how can i know if the key that pressed is 'A' or 'a' or '5' pr '%' - ?
Thanks for the help

Hi Yanshof,
Is this win32 function of any help to you. It will enable you to translate the vkCode member of the KBDLLHOOKSTRUCT to a character code.
MapVirtualKey Function
The MapVirtualKey function translates (maps) a virtual-key code into a scan code or character value, or translates a scan code into a virtual-key code.
To specify a handle to the keyboard layout to use for translating the specified code, use the MapVirtualKeyEx function.

Thanks,
I will try this now.
Is there is some .net framework class that i can use ?
As you said - the MapVirtualKey Function is win32 function.

How can i know if the user pressed on LShift+Q or just on Q button ?

It seems that with the DayaGridView SelectionMode property I can only select one selection mode like FullRowSelect or FullColumnSelect. But I would like the ability to select either a full column or a full row. Just like in a Excel spreadsheet.
Is this possible or not?
Thanks,
Mark
