There are macros to encapsulate some useful windows messages in the WindowsX.H file.
What with everything built on a 'foundation' or 'template' library of some sort these days, I think people tend to forget about WindowsX.H

hiho@ll
i need to login into a website, controlled by my c++ prog
for example i have a menu-button "Login to website"
my prog knows the username and password
and i need to login with standard browser or internet explorer in the website?
i've tried with http://user:pass@www.mytestlogin.com
but it didn't work
i just get the login site, where i have to fill out the HTML-Forms and submit it
may i can generate the needed HttpRequest and let the Internet Explorer Read the HttpResponse? (how can i do that?)
are there any topics in the forum i haven't found about this subject?
thx@ll

You could just submit the login form programatically by examining the site's login page HTML. See this[^] section for code samples.

i just can send the HTTP Request, but how do i tell Internet Explorer (i mean i need a new Internet Explorer Window, not a window which is part of my application) to receive the Request?
So, i need to open a new Internet Explorer window and the user is in the member area of the website i opened
how can i handle the http request/responses to do that?
thx

The problem is almost cetainly because the site is expecting a POST of the username and password, which can't just be stuffed on the end of the URL.
A post looks something like this (the exact names of the fields USERNAME and PASSWORD could maybe be determined by viewing the source of your particular web page).
POST /logon HTTP/1.1

What I want to do sounds quite simple. I'm firing off a new process from my application, and want to be able to set the color of the new process windows' top-bar (where the title and the minimize/maximise/close buttons are) from my process.
I've spent weeks combing the MSDN docs to do this, with no luck.
The closest I've found is the SetSysColors which allows me to set the topbar color, but for the whole system. Is there an equivalent function that takes in a hwnd handle? Alternately, what are my options? From my research it seems like I could hijack the messaging events to the window, and fudge the paint callbacks, but that seems way too drastic. I've found plenty of functions to move windows around, change the title text, etc... Are there any to control the color?
Thanks in advance.

The only thing that I can think to do here is API hooking, you can hook the GetSysColors function for that application and return the values you want. I don't know if this will work for the top level window or not, but probably. It still seems like a bit of work, but there are reasons this stuff is done at the global level, users should be able to set their colors to whatever they want and not have applications changing them.

an app (A) create a sub-process (B) and they communicate each other.
A uses ReadFile() in threads to read stdout and stderr from B.
but function ReadFile() blocks there even B was terminated.
is it just this way or something wrong?
how to solve the problem?

my app retrieves a file path from command line by double-clicking the file in Windows explorer.
Unfortunately, the file path is in 8.3 format.
my questions:
1) how to pass full-path to app when double-clicking the file? e.g. set register in other ways.
2) if 1) is impossible, how to change 8.3 format to full-path? as i tested, the function GetFullPathName() still returns a 8.3 path.
thx

hi,
thx.
i don't know the function.
i read vc doc for it, vc doc says the function works for win98 and above, but our target is for all windows (incl. 95) - this is company's policy.
any other solutions?
(modify: it works very well on Win98)

I'm curious why your program would care whether it was 8.3 or LFN. Most file I/O functions will work with LFN and all of them will work with 8.3 format.

You should wrap the %1 in the registration data in quote marks. You should also put your program's path in quote marks. For example:
"C:\Program Files\IncludeProg\MyProgName.exe" "%1"

that is why i got the trouble.
u sure it passes full-path to app other than 8.3 format?

Hello,
I have a GUI application where the user can set the background color for a plotting control.
My question is how to select a foreground(text) color that will "contrast" with the user selected background?
COLORREF bg = GetUserPlotColor();
COLORREF fg = F(bg);
That is, what is the code for the F() body?
TIA.

I'm no colour expert, but I did encounter this while writing a custom-drawn tree control a while back.
Have a look at this[^] article that should point you in the right direction.
However, in the end I think I settled for a simple XOR technique, where I XOR'ed my selection colour with white (#FFFFFF), to get the corresponding contrasting text colour. This is definitely the easy route, and will probably give unsatisfactory results on certain colours, but it works for me.
By the way, I found this[^] little web applet useful.

I have played around a bit with inverting frame-grabbed images, and I found that the XOR technique usually works nicely.
Where it will not work well is with grey-scales which are close to mid-range, for example, if you have RGB-15 (5-bits of each colour, high order bit unused), where the R, G, and B values are all half-range = 15 decimal, i.e. the pixel is 0011 1101 1110 1111, XORing will give 1100 0010 0001 0000, i.e R, G, and B are all 10000 binary = 16 decimal.
For cases like this, the XORed text will be very difficult to make out.
To get around this, you could saturate (force to maximum or minimum) each colour component, then XOR / invert the result. For my example, the 15 decimal component values are forced to 0, then inverted to give 11111 binary, which should be visible.

This is an old function that generated a suitable shadow color for drawing 3D elements. If you reverese it, it should do what you want:
COLORREF MakeShadowColor(COLORREF rgbColor)
{
COLORREF rgbRetval;
if (rgbColor == RGB(255,255,128))
{
rgbRetval = RGB(128,128,0);
}
else if (rgbColor == RGB(192,192,192))
{
rgbRetval = RGB(128,128,128);
}
else if (rgbColor == RGB(128,255,255))
{
rgbRetval = RGB(0,0,255);
}
else if (rgbColor == RGB(0,0,0))
{
rgbRetval = RGB(128,128,128);
}
else
{
short iR = (GetRValue(rgbColor)+1)/2;
short iG = (GetGValue(rgbColor)+1)/2;
short iB = (GetBValue(rgbColor)+1)/2;
rgbRetval = RGB(iR,iG,iB);
}
return rgbRetval;
}
<pre>
<span style="background-color: rgba(255, 255, 0, 1); color: rgba(0, 128, 0, 1); font-family: Verdana, Arial; font-size: 8pt; font-style: italic"> onwards and upwards... </span>

Firstly I'd like to say that English is not my native language, so don't be angry with my mistakes.
I have a following problem.
I have writen program in c++ and now I'm working on making GUI. I do MFC Dialog based application. The problem is with edit box. My program do lots of iteration (~20.000). After each iteration I want to have printed number of iteration and values of some variables. this way in multiline edit box i want to have some kind of raport. I maneged to do it but i think my solution is not optimal and proper. i have simply added CString variable to EditBox and in each iteration I add temporary String refering to current iteration to whole string variable. It looks like this:
/*CString mWholeString
CString mTmpString -these are examle variables*/
mWholeString+=mTmpString;
and after finishing all interation i do UpdatData(FALSE).
It works but I think that it works slowly and there may be batter solution. Is this possible to print text like in console application e.g. create array of CString and print it in edit box using for loop?
I thank in advance for any direction.

You could possibly write your own output window. If you don't need editing of it, this would be a good solution that you could make run a lot faster. Just inherit directly from CWnd or CView and use the CDC::TextOut function.

This is probably going to be a tad better solution.
