For splash screens, just look at the code of Wordpad in MFC Samples. What is done is :
You create a dialog containing only an image (or whatever) with no border or whatever, which is displayed by the app, and killed in the OnIdle function after a while. Intersting thing is you can display various things (like animations, or plug-in loading à la Acrobat Reader) doing it this way.
I never tried the splash screens in VC++ which Christian is talking about, however, it may be worth a try.
As yor displaying a bmp, with MFC, just create a CStatic somewhere and load a bmp in it. Might also go that way in Win32 API only.

you can use BitBlt() and StretchBlt() functions to get the job done and look up MSDN it has some samples on these 2 func's.
BitBlt() just places the bmp on to the dlg and using StretchBlt() u can stretch the bmp to any size u want.

cool! ! thanks everyone... im going to try to get these things working... the splash screen does sound simple enough. Though I played with CStatic last night and couldnt get the picture to display, i kept getting an error when I tried to load my bitmap ..(16-bit image, is that ok?). ill try documentation on the Bitblt() and StretchBlt to find out more on that task.
thanks,

Hi,
I'm working on a bit of an IM app (connects to msn messenger network) and i'm having a bit of trouble trying to decide how i should go about the message windows. Rich edit controls do nearly everything i need except appending text, the only way i can find of adding text is by keeping a buffer and appending to that then changing the richedit control (i.e. say we have 5k of text in the control and i want to insert a line at the bottom, i have to keep another copy of that 5k of text seperately and effectively wipe the rich text and start over) this method seems like it will introduce flicker and seems a bit of an ugly solution.. any thoughts?

You can add text to a richedt by "selecting" a null range at the end of the existing text and then "replacing" it with the text that you want to append.
SetSel(-1,-1) and then ReplaceSel() IIRC.

I've set up a scheduled task to run whenever a user logs on. After the desktop starts, the window is not visible. However the process is listed in the task manager process list.
I use explicit calls to ShowWindow and SetWindowPosition in the OnInitialUpdate function of the view class. So why doesn't the window appear when the desktop starts?
The program has to start every time a user logs on and it has to run with admin privilages so that users can't kill the process.

Meaning you run it under an account that's member of the Administratoprs group?
And where exactly would that "user" get the windows station and the desktop of the currently locally logged on user, and especially the privileges to use those objects?
Try reading this article, and you're in a much better position to do what you want to accomplish.
Personally I think you're nuts, running a process with admin privs on a users desktop, especially when we all know how easy it is to interact with such a window to gain full access to the machine.
If you want a better solution, you should probably run your service as just that, a service, and then let the UI run in the locally logged on users context, talking to the server using e.g. RPC.

Hi
I have a library which consists of header and source file. I created the Win32 Static Lib project in visual C++6. It then compiles ok and leaves some objects and .lib file in the Debug folder.
I then created another console project and attempt to reference the x.lib in the debug folder in the Win 32 Static Lib but it gives me 102 errors say "unknown character at 0x95" or something like that.
And when i double clik on the error to see where the error is in the editor, the message box pop up and say that the file is binary and can not be read.
Does any one know how to solve this problem??
Ah i also forgot to mention that i even have tried to add the x.lib into the link option in the project setting! This time it reduce to 3 error but alway say "undeclared identifer" which is quite weird to me since i know how i declare it is quite correct.
Regard,
Cuong Tong

It would be (more) productive if you provide the actual compiler /linker output. It is kind of difficult to guess from the information you supplied.
P.S. Before linking go to ProgectSettings->Link->Customize and check "Print process messages" box

similar to Windows Explorer, with a treeview to look at
my own computer's data, with no problems... need to
add "My Network Places" to this (similar to Windows Explorer)
and be able to go out on
the network and get similar info for other
workstations.. plus I need to be able to create folders
and copy files to these PCs... any help or

Is there a better way to write this very simple code?

#include <iostream.h>

int playersScore = 0;

Hey, you're back! Good on ya
The biggest problem here is that you have lots of repeated code e.g.
if (playersScore > highScore[3])
{
highScore[9] = highScore[8];
highScore[8] = highScore[7];
highScore[7] = highScore[6];
highScore[6] = highScore[5];
highScore[5] = highScore[4];
highScore[4] = highScore[3];
highScore[3] = playersScore;
break;
}
So, you have the repeated lines inside the if-statement. And then this kind of thing is repeated itself many times. Try using a for loop.

I think, what you want to do is sort the players score into the 10 sorted scores. right ?
if you want that, try making the array size 11 (knowing you just have 10 valid entries). After the game, put the players score at place [10] (11th place) an begin a descending for loop at number 9 downto 0.
In the loop, do something like:
if(highscore[i]

What john has suggested is a simple bubble sort. If the data is completely unsorted, a full bubble sort needs two nested loops, to ensure everything gets to where it needs to be.
Are you doing this for fun or for homework ? If for homework, you'll need to take this sort of approach, because the idea is to learn. If for fun, the STL is a collection of containers and methods that work on them which makes this job very easy. You could either pass the values into a vector, and call sort on it, deleting the end item, or use a map, which sorts for you right away, and remove the lowest item. I suspect you're doing homework, so I won't elaborate further, but if you're able to use STL, check out my articles on the site, or ask some more.

In the Microsoft SDK, you will find this tool, (Dependency Walker) which appears to be quite sophisticated, but, for which the Microsoft MSDN site provides very little useful information. I'm wondering if any of you programmers have any thoughts or suggestions about its utility. Do any of you use this tool?
Feng Yuan, author of, Windows Graphics Programming has this to say about the Dependency Walker:
"Dependency Walker (depends.exe) lists all the DLLs your module imports implicitly in a nice recursive way. It helps you to get a clear understanding of how many modules will be loaded into your program when it's running, how many functions are imported. Check this simple MFC program; you will be amazed how many functions are imported without your knowledge. You can use it to check if a program will run on the initial version of Windows 95, which does not have system DLLs like urlmon.dll or provide so many exported functions in ole32.dll."
Is there source code available for us inexperienced code nitwits to investigate? I'd like to know how they did it. ...not that I'd actually understand it, but, I'm sure it would make interesting reading.

To produce good quality installation programs this tool is
essential. You need to use it to determine what DLLs to
include with your installation package.
You can cross check them here:
<http://support.microsoft.com/default.aspx?scid=/servicedesks/fileversion/dllinfo.asp&fp=1>
to eliminate ones that are certain to be on your user's computers.
Obvious, legal caveat, don't distribute Dlls that you don't
have the right to distribute.
Oh, one other thing that occasionally comes along to bite you,
sometimes other people's code loads the dll's by hand (LoadLibrary)
which is obviously not detected by the walker. This is a major
PITA, but it happens, and you have to watch out for it.

Its also helpful in tracing errors. You can sometimes find what function the error occurred in by looking up the address in Depends.

Okay, this sounds like a simple question but I don't know where to look for info on it.
I want my program to be able to open user documentation. When it's a doc or txt file, I can just use ShellExecute() but, for unknown file types, it's going to need a default program to use. How do I have a program shell to a specific other program? For example, how do I tell Notepad to open a specific file?

Hello,
I would like to know if there is any manner in which I can prevent my application (or its process) from exposing its diagnostic information to tools like Spy++.
Any pointers in this regard would be most helpful!
Thanks!
