iconify application?

hiho@ll

i want to write an app which can iconify another application (should be independent what kind of application it is)

the problem:
i have a prog running the whole day
the prog itself can no the iconified to the systray
well, that's not correct
it is in the systray, but it is also in the task bar
so i don't want to see it in the taskbar because it just waits the whole day and does most of the time nothing (but it is needed!)

anybody knows how i can make the prog just sit in the systray?

that was a great hint
but:

i made a prog as described in the tutorial
it worked great
now i tried to catch the HWND from a mouseclick to get the window for which i want invisible the task bar icon (the systray should be visible)
what i do:
catch the click
use WindowFromPoint to get the clicked window
create a new CWnd which is invisible
set the parent of the clicked window to the invisible window

well the whole window is invisible
hmm

don't realy know the problem/solution
what could be the problem?

anybody knows an answer?

thx

If you remove them, do the linker errors persist?

looks like you're missing the implementation for the F2X, BigInt and Point classes (and maybe others). do you have the files where those classes live ?

if these classes are part of an external library, make sure the appropriate .lib files are listed in your Imports.

If I remove these two functions i.e

EC_Domain_Parameters dp = NIST_B_163;
I dont get any link errors.
another thing is that the library Im using doent have any .lib file
u can find the library here

plz help me.

You're right there's no .lib file in the zip download. You have to include the source files in your project. From the manual: There's "Microsoft Visual C++: Add the ”borZoi.dsp” project file to your project’s workspace and add the header file directory to your project’s include files path." In my VC++6.0 this is done by "Project->Insert project into workspace..." Did you do this? You will include the source files (.cpp) in your project, and you should be able to see the classes in the class pane of VS. Remember to add the header file directory as well.

I guess that the reason why you only see the linker errors after adding your to lines of code is that this is the only point in your app where you call use_NIST_B_163(), and hence this line makes the linker look for all the symbols that use_NIST_B_163() depends on.

You can just click the email button on my reply. I'll gladly look your project over, but I only have VC++6.0, so if you use VC.NET I can't help you.

ok, this is what it looks like to me:

This is a solution that you need to load with Visual Studio and compile/link. When you do that it produces a static link library (the .lib file) which you then include to your imports.

How to get the virtual-key code value of the character?

For example, i want to get the virtual-key code value of the char ':'.
How can i get the value?

Handle WM_CHAR message , It nChar argument contain the value for each key.

BTW Virtual keycode for ':' is undefined and it is equal to 3A(HEX) or 58(DEC)

Hello,

I don't think that there is an easy way to do it, but you can always use a map:
<list>

Create a separate module create a private map that on initialization maps all virtual key codes to their ASCII (or UNICODE) counterparts.

Create a routine that returns the key code for the character passed to it.
Example:

// module CharToVKCode
#include <map>

static std::map<TCHAR, UINT>  g_KeyCodeMap;
static bool g_bInitialized = false;

static void InitializeKeyCodeMap()
{
    g_KeyCodeMap.insert(std::make_pair(_T(SomeChar), VK_SomeChar));
    // do this for all virtual key codes
    g_bInitialized = true;
}

int CharacterToVKCode(TCHAR Char)
{
    if( !g_bInitialized )
        InitializeKeyCodeMap();

    std::map<UINT, TCHAR>::const_iterator ci = g_KeyCodeMap.find(Char);
    if( ci == g_KeyCodeMap.end() ) 
        return -1;

    return c_i.second;
}

If I remember correctly, the VK_CODES in ASCII builds is the ASCII code of the character. So the VK code for ':' is static_cast<int>(':');. I could be wrong about this though.

I suspect this means that this function is not defined in your header file. Why are you passing char arrays around ?
