Add the path of your application to - [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run]. You can make use of CRegKey[^] for that. Then, that application will be started during startup.

Thanks for reply.I am getting problem to how can i start as a hidden mode.I set the path in registry.Pls help me to hidden mode.
|
|
|
|

during startup you can pass a commandline argument to the application. For instance - /startup. In your application get the command line by calling GetCommandLine()[^] and hide accordingly.

Command line problem?
When System is start that time my applcation is run in hidden mode?
I am set path of exe in registry but i havn't know how to use command line for startup.So plz help me
|
|
|
|
|
You can pass the command line together with exe path. For instance, in your case, add the registry value as C:\hello.exe /startup. And if you call GetCommandLine() in your application, you will get the /startup string. Hope its clear.

Jijo.

I see you've put plenty of output statements in your program, to show what's happening or failing - might help if you shared the output of the program with us, just in case it gave some pointers as to the problem?
|

|

thank you for your reply!
just "connect ..." was put out,everything seemed to be fine.
but after debug ,i found:
if(0 == uReturn) //uReturn =0 all the time!
{
break; // break every time!
}
....
pclsObj->Release(); //often return "access deny"

I notice you don't check the result of the enumerator Next call:
HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturn);
Maybe its HRESULT indicates an error?
One last thing - maybe you could prototype & debug using VBScript, as documented here[^]? Then you can be sure that the use casse you're implementing is valid? And it's a lot quicker to prototype in a scripting language...
|
|
|
|
|
yes,i checked it
if(SUCCEEDED(hr))
{.......}
pEnumerator->Next SUCCEEDED(hr) return False,
but what leads to the error

The HRESULT value may give you a hint. I would be willing to bet its returning 0x80070005 - E_ACCESSDENIED.

maybe it was
but right now ,i created a account in target machine ,the same username and password with my machine, and the code worked !!!!
i still don't know why

Seems pretty obvious it was security related...it failed until you created an account on the other machine with the same credentials as the one you were running the program with.
I notice in your program that you prompt for a username and password, but then just use hard-coded values. That seems to be the single deviation between your program and this sample one in MSDN[^].
I think you need to do some reading, to understand how all this works, rather than taking a sample and poking it to try to get you get what you want.

Hi,
I'm working on a project with the following configuration:
- several static libraries (*.lib) which contains some services.
- MFC application which link to the above libraries in order to use it's services.
All of the projects stored in the same solution.
One of the static libraries contain a static array with a predefined size.
I know that if I add the header of that library to my MFC application project(the only project which is an executable file) and recompile the entire solution , the array will be allocated according to the specified size in the overriden file.
The problem is that now I don't have the libraries in my solution(instead - I only get the *.lib files),therefor, I can't recompile those libraries(and still - I need to change the size of that array from the MFC application project).
Is it possible?(Is there a compiler setting which I missed????) 
With best regards,
Eli

You can't change the size of the array. The libraries only 'know' the size of the array that was in effect when they were originally compiled.

Hi experts!
well as i'm developping an advenced chat application using MFC winsock (VS2005) under windows Vista and windows XP, i faced some problems,i could solve some of it, however i couldn't solve other problems..
- the first problem is when the client opens a public chat room or any other window, the rest of application must stay responsive and the user can access it! the problem is when i use DoModal method for the dialogs or any similar method (that have it's own message loop!) the main window is not responding anymore!
- tried solutions:
i tryed UI threads but i still have the same problem!
wel hope you have a solution for me.. (maybe about Non-Modal dialog boxes or so..)
(just an example: i want sth like in yahoo messenger where the user can open many windows and still able to use the main window or any other window)
waiting for your answers
Some People dream of success while others woke-up and are working to get it..

|
|
|
|
For short, how to create many dialogboxes and the main window stays responsive and i can acces any shown window (like the messenger chat)
|
|

Thank's bro,
that's it, it works now..

Hi all !
I'm using the MFC sockets mechanism for TCP\IP communication (CSocket, Srialization ability etc.) in a Process that spawns some threads.
It works fine until I deliver the socket pointer to one of the threads created by this process so that it can use it to send messages through this socket too - the application then fails, and if I understand correctly it is since the only thread allowed to use this socket is the one created it (in my case the main process).
I'm looking for an elegant solution to this limitation (I can go around the problem in several ways but it might affect the complexity and run-time of the program).
Any suggestions ???
Thanks in advanced,
Amit
