I am currently creating an application which requires to launch an application in backgroud and the user should not be able to see the application window. I am using CreateProcess API to launch the application in background and using the STARTUP_INFO structures's flag (STARTF_USESHOWWINDOW)to hide the newly launched application's window. But by doing this though the application is launched in background and is not visible to the end user the splash screen of the application is visible to the end user. I have tried manipulating few flags of STARTUP_INFO structure but it didnt helped. I am looking for any alternative way by which i can accomplish the aforesaid task or any usefull information????

You might not be able to; if the application is coded to create and show a splash screen. However, most MFC applications pay attention to the /Embedding command line parameter and will not show the splash screen (and will remain invisible) under those circumstances. Have you tried contacting the developer of the application to ask them if they support something like a /nologo or /nosplash command line parameter?
If you wanted to get fancy, you could try two other things: launching the application on another, non-visible desktop, but you might have to figure out new ways to interact with it, or install a short-term hook (you will need to create a DLL for this) that can catch and "pop" the splash screen.
Peace!

Hi all;
I want to set a number for a function for example:
19928=myfunc();
and then by calling this number...
2:is there any way to have a handle to a process by giving
it's name?
Thanks.

|

why do you want this for ??
you cannot do that.
however, if you have many functions that may be called depending on an index, you could set them in a pointer-to-functions array...

This makes no sense. Please explain further.

There might be another way, but the one I am thinking of uses Process32First() to get a list of running processes. Look through that list of processes until you find the one of interest. At that point you will have its process id and module id.

Hi
I am writing an application which needs to know if the user is having internet connection enabled or not.
I want this checking to be done automatically by the application, I donot want to pop up connect internet dialog.
Can anyone tell me if there is any API/function to findout that the machine is having internet connection.

mr ruchir use his api
InternetGetConnectedState
This function retrieves the connected state of the local system.
BOOL InternetGetConnectedState(
LPDWORD lpdwFlags,
DWORD dwReserved);

InternetGetConnectedState() only works for modem connections. It will return FALSE even if the user is connected via a network. The only truly correct method of knowing is by actually trying to connect to a known website. If it works, then you're connected. If it doesn't work, then you're probably not connected (not definitely - the website might be down).

Hey
I was just searching on the MSDN and I got something WinInet API's in which there is function InternetOpen(...) will it help me??
I mean just checking handle (if null then no internet, if not null internet available.)
Do anyone has any idea about this WinInet API and tell me whether it will help me??
Regards.

i don't think soo,as msdn state that "This function initializes an application’s use of the Windows CE Internet functions." the equivalent function for windows is InternetOpenUrl().

This function initializes an application’s use of the Windows CE Internet functions."
I think there is some confusion. Windows function call InternetOpenURL uses Handle that is returned by the function call InternetOprn(...)
Pls see below
InternetOpenUrl
Opens a resource specified by a complete FTP, Gopher, or HTTP URL.
HINTERNET InternetOpenUrl(
HINTERNET hInternet,
LPCTSTR lpszUrl,
LPCTSTR lpszHeaders,
DWORD dwHeadersLength,
DWORD dwFlags,
DWORD_PTR dwContext
);
Parameters
hInternet
[in] Handle to the current Internet session. The handle must have
been returned by a previous call to InternetOpen
Plz correct me if I am wrong.
What I could conclude from the MSDN excerpt is that "InternetOpen returns handle to the internet session if connected and if not it will return null, using this handle we can open an URL using InternetOpenURL() function".
Also the exact use case is "check if user is connected to the internet".
Thanks n Regards

Yeah you are RIght!,Sorry i Interpreted it wrong.

InternetOpen according to MSDN "InternetOpen is the first Win32 Internet function called by an application. It tells the Internet DLL to initialize internal data structures and prepare for future calls from the application."
So it just Initializing the Local Variable ONly , not checking the State of Internet.i.e. you can simulate the use of Internet api using LOCAL WebServer.
But InternetGetConnectedState return with actual Internet State.
TRY IT!

Hi Thanks for information.
I m Still having some doubt and some confusion.
Coming to doubt:-
I want to know whether user is connected to the internet it should not be application's concern that user is connected to the internet via LAN/PROXY/DIALUP. How to do that??
(connected to internet means connection is esatblished not just that internet is configured.)
Coming to Confusion:-
As you said that the
InternetOpen according to MSDN "InternetOpen is the first Win32 Internet function called by an application. It tells the Internet DLL to initialize internal data structures and prepare for future calls from the application."
but in the description of InternetOpen they say
InternetOpen
For a general utility or application, you should start with the InternetOpen function. By specifying the Internet agent you want to do the Internet access (for example, Microsoft Internet Explorer), the type of access you want, and a few optional flags, this function returns you a handle to an Internet session. When you are finished with the connection, you must close it by passing the handle to the InternetCloseHandle function. For example:
HINTERNET hInternetSession;
hInternetSession = InternetOpen(
"Microsoft Internet Explorer", // agent
INTERNET_OPEN_TYPE_PRECONFIG, // access
NULL, NULL, 0); // defaults
.
.
.
InternetCloseHandle(hInternetSession);
This will make a connection to the Internet, using the Internet agent "Microsoft Internet Explorer," and return a handle to the connection, if successful. By specifying the parameter INTERNET_OPEN_TYPE_PRECONFIG, you have requested the agent to use certain values that are stored in the registry. The rest of the parameters are set to use the default configurations. In one simple call, you have made a connection to the Internet—assuming nothing went wrong with the connection, of course! With the returned hInternetSession handle used as a parameter to the other functions, you can start accessing Internet information.
So Which one to prefer and am I interpreting correct that this call will make connection and return internet session as handle.

I've seen a number of apps lately that have a tab control in the About dialog. At least one of the tabs will have links to email and check for updates. I know how to add a tab control but I thought for the About dialog to use links, it had to be derived from CDHtmlDialog? That's what I use to create mine so that I can have such links but when I try adding a tab control to it, the tab control is layered on top of the html section so that they are two different dialogs. Does anyone know how to do this or where I can find an example?

I have written an app in VB and am trying to rewrite it in VC++. What the app does is work with large text files(up to 30 meg) containing code to drive CNC machines. I ran the wizard to create an exe, I changed the base class to CRichEditView. I added the line CRichEditDoc::m_bRTF = FALSE; to allow it to work with plain text.
I built the base project in release and ran it. The load time for a sample 16.7 meg file is 4 times greater in the VC++ version than it is in the VB version.
Does anyone have any ideas what I'm doing wrong?
Thanks
Bryan

Perhaps you are doing nothing wrong. Comparing the running time of a VB application to a VC++ application is not a very fruitful exercise as they are two very different development platforms. Each language has its own strengths and weaknesses, not to mention that each is a different distance away from the underlying machine code depending on what is happening at any given moment.

Thanks for the reply.
The intent is not to evaluate which code runs quicker. I noticed the problem when I created the exe and tested the function. The load time was unacceptably long. This is my first C++ project and I'm trying to learn to make it work better than the standard MFC wizard.
I have commercial apps that do similar things that load 50% faster than my VB code and were written in C++, so I know it's possible.
Thanks

Without actually seeing how you are loading the file, it's hard to offer any suggestions.

Perhaps you meant 150% faster. 50% implies twice as long or half as fast.

Again, thanks for the reply.
I guess it's time to pick up some books on MFC and read them instead of this message board. I did try to take a short cut and find someone that knew MFC inside out and give me a quick answer, hard work and study will be the correct answer.
You have helped me though, reaffirmed some long known truths, advice is worth exactly what you pay for it and now matter where you go there are people trying to boost their ego by taking cheap shots at you.
So thanks for the tips. Imagine that, comparing run times between programming languages is fruitless, dang could have knocked me over with a feather when I read that.
50% faster really means slower. Guess technically you are correct, thank you for pointing out the error of my ways.
By the way I sure hope you don't by any products offering you 50% more for free, I'm sure they are trying to screw you. Guess I'm not the only person in this world who uses percentages loosely.
Thanks for making my first post to any such board so informative, it will be my last.
