I added the splash window component from the VC6 components in my application, usually, as far as I remember, this is really a simplistic procedure, and should not cause any problem at all.
but alas, things started to go wrong.
at some point, when the splash screen is visible, my application receives a message ( WM_SIZE ) and in the handler, I call AfxGetMainWnd and it returns a pointer to my splash screen CWnd instead of the real mainframe CWnd.
CMainFrame* pMainFrame = (CMainFrame*)AfxGetMainWnd();
in the debugger, pMainFrame is wrong, and shows as a CSplashWnd.
in MSDN, the AfxGetMainWnd documentation says this :
If AfxGetMainWnd is called from the application's primary thread, it returns the application's main window according to the above rules. If the function is called from a secondary thread in the application, the function returns the main window associated with the thread that made the call.
Would that be the case ? I don't have multiple thread, but the splash CWnd could be the secondary thread ?
Any idea ?
Thanks.

DOes your application's main window exist while the splash screen is visible, or does it get created after the splash screen goes away?

the splash window is created at the end of my main frame OnCreate; does not work either if it is done at the beginning.
I tried different things, and i seems to "work" if I SetFocus back to the main frame class as soon as the splash window is created.
but this hack doesn't look good to me, it might show something that is completly wrong with what I do with mainframes and other windows; I have a complex top level UI.

ignore the resize event if the window is a splash screen.

but it's not the splash screen ( CWnd ) that receives the WM_SIZE, it's another CWnd, which is part of my UI.

Hi Friends

Or any idea ?

Are you wanting to mute all input devices? If so, this article might help.

Using environment variables is usually not a good idea. In any case, you can get them via the following registry keys:
HKEY_CURRENT_USER\Environment
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment
Also GetEnvironmentVariable().

I want to solve a problem that I have; my main problem is to execute my program outside my PC. As i use SQL SERVER 2000, I usually change manually in my program this variable :
dbinit.AddProperty(DBPROP_INIT_DATASOURCE,OLESTR("sem1");
"sem1" is the name of my sQl SERVER 2000 path.
Now I need to replace this path by a variable so that if I install my program any where, I will put the environnement variable and i my program I use it because the name of this variable must be the same.like :
dbinit.AddProperty(DBPROP_INIT_DATASOURCE,VARPATH);
VARPATH is an environnement variable.
How can I remplace "sem1" by an environnemnt variable ?

I'm not sure exactly what you are asking, but is SetEnvironmentVariable() of any help?

Like David said:
Search the MSDN for GetEnvironmentVariable().
If you dont want to use it, look for Registry Access Methods and use the path he mentioned.
You also could use a higher-level file access which evaluates the "Command Line"-Variables and use that instead.
Or, if your app is merely a test and not productive, you could pass the name as a parameter (e.g. "myExe -server=sem1"). Using that approach, you could then write a batch file which gets the "-server="-parameter from an environment variable.
Cheers,
Sebastian

With getenv it works well.
thanks

You can use 'GetComputerName' and 'GetUserName' to retrive name of computer and user name resp.
Set/GetEnvironmentVariable API should help you work with the environment variables.

those variables are not known in Visual c++,
I have an error undeclared variable:
my sentence is :
dbinit.AddProperty(DBPROP_INIT_DATASOURCE, getComputerName() );
I insert these libraries :
#include <stdlib.h>
#include <stdio.h>
but the error is there,
what to do ?

Hi, i have some troubles with a CListCtrl... I want to do a Report Clistctrl, like an exel, with 5 columns and unlimited rows. Well,my problem appears when i need to put 2 or more lines in one possition of the ClistCtrl, then my question is, is it possible? it means, can i put a paragraph with 60 characters in each line? or the only thing configurable is the colum width...
Thanks in advance, to see if somebody can remove to me from this doubt. If that cannot be done with the CListCtrl... what do you recommend to utilize?
Bye!

yeah, this two exemples are good, but, mi problem is to write two lines or more lines in one position, it means, i want to write in m(1,1)= "12", in m(1,2)= "Hi all of you, i have problems with Visual C++" in two lines, not in one, i dont' want my position have more than x caracters per line, but shows all the text in some lines, not show "...". Maybe my english is very bad, and i'm sorry, if you don't understand, i can improve my explanation.

CListCtrl does not support muliple rows as far as I know, sounds more like its time to switch to a grid, you can use one of the Microsoft Grids (which are pretty easy and simple) or MFC Grid control 2.26[^] which looks interesting (havnt tried working with it my self).

hiho@ll
what i have:
a dll
what i want:
a list of every function available in the dll and the parameters each function needs (the return value would be cool too)
seems like i need something like "function prototypes" from a dll
the problem:
to retrieve the function names i think i will use pexport program cause source is available (i have to read the source, didn't yet)
but it only can read function names, but i need the parameters too
question:
1. how can i read parameters of a dll function if i only have the dll?
2. is there something like a dll file format, or a documentation how a dll works (dll header, dll symbols etc. at which offset in the dll files can i find what ...)
3. is there a simple windows function to retrieve this stuff?
thx@ll

This can easily be obtained by examining the PE file format, specifically the .edata section.

You can't necessarily get the function parameters - in general you can't. If the exported names are mangled (they will contain "funny" characters) then you can, see the UnDecorateSymbolName API. If the functions are extern "C"d this information is lost. You can get this kind of information from the symbol file (.pdb) if you have one for your .EXE (or DLL).
