Re: How can I display current time in dialog static control

buf has garbage value now In my debugging i have seen that if 15:22:34
Then in buf shows L(1) only show what is the reason?
so then this character display in the static control

The format string is "02d%:02d%:02d%" or "%02d:%02d:%02d" ? Wink | ;)

Need to brushup those old C lessons? Big Grin | :-D

BTW, Why can't you use CString?

SYSTEMTIME time;
GetLocalTime(&time);

CString csTime;
csTime.Format( _T("%02d:%02d:%02d"), time.wHour,time.wMinute,time.wSecond );

SetDlgItemText(IDC_STATIC1,csTime);

I apoligize that since i don't have VS2008 installed, the above code snippet is compiled in VS6.0. So try it.

Why do you do this in the OnPaint ?

SetDlgItemText(IDC_STATIC,(LPCTSTR)str);

you want to print str or buf ?

ya buf i have chnaged , the code is working but its not display the hh:mm:yy its only shows current hours in the static control

<br />
 GetLocalTime(&time);<br />
  char str[256]; <br />
 <br />
 sprintf(str,"%d:%d:%d",time.wHour,time.wMinute,time.wSecond);<br />
 <br />
 std::string str1(str);<br />
 int len;<br />
 int slength = (int)str1.length() + 1;<br />
 len = MultiByteToWideChar(CP_ACP, 0, str1.c_str(), slength, 0, 0);<br />
 wchar_t* buf = new wchar_t[len];<br />
 MultiByteToWideChar(CP_ACP, 0, str1.c_str(), slength, buf, len);<br />
 SetDlgItemText(IDC_STATIC1,(LPCTSTR)buf);<br />

the code working but display hours only i have increased the size of control but still not able to see the entire string

<br />
 GetLocalTime(&time);<br />
  char str[256]; <br />
 <br />
 sprintf(str,"%d:%d:%d",time.wHour,time.wMinute,time.wSecond);<br />
 <br />
 std::string str1(str);<br />
 int len;<br />
 int slength = (int)str1.length() + 1;<br />
 len = MultiByteToWideChar(CP_ACP, 0, str1.c_str(), slength, 0, 0);<br />
 wchar_t* buf = new wchar_t[len];<br />
 MultiByteToWideChar(CP_ACP, 0, str1.c_str(), slength, buf, len);<br />
 SetDlgItemText(IDC_STATIC1,(LPCTSTR)buf);<br />

How to convert grayscale image(.tif )to black & white ?

To do that, you just need to de-saturate the image.
The RGB colour-space does not easily lend itself to this operation, and the HSL colour model is far more useful here.

In an entirely non optimized method, you would:

Repeat loop for all pixels in source image
(1) convert pixel RGB to HSL
(2) drop the S value to 0
(3) convert back to RGB
(4) dump the converted pixel back

Here's some routines for colour-space conversion:

// Input: h, s, v in range [0..1]
// Outputs: r, g, b in range [0..1]
void hsvToRgb(float h, float s, float v, float *r, float *g, float *b)
{
     int i;
     float aa, bb, cc, f;
     
     if (s == 0.0) // greyscale
        *r = *g = *b = v;
     else
     {
         if (h == 1.0) h = 0.0;
         h *= 6.0;
         i = floor(h);
         f = h - (float)i;
         aa = v * (1.0 - s);
         bb = v * (1.0 - (s * f));
         cc = v * (1.0 - (s * (1.0 - f)));
         switch(i)
         {
           case 0: *r = v; *g = cc; *b = aa; break;
           case 1: *r = bb; *g = v; *b = aa; break;
           case 2: *r = aa; *g = v; *b = cc; break;
           case 3: *r = aa; *g = bb; *b = v; break;
           case 4: *r = cc; *g = aa; *b = v; break;
           case 5: *r = v; *g = aa; *b = bb; break;
         }
     }
}
           
#define myMin(a,b) (a<b?a:b)>
#define myMax(a,b) (a>b?a:b)
#define noHue 0

// Inputs: r, g, b in range [0..1]
// Outputs: h, s, v in range [0..1]
void rgbToHsv(float r, float g, float b, float *h, float *s, float *v)
{
     float max = myMax(r, myMax(g, b)), min = myMin(r, myMin(g, b));
     float delta = max - min;
     
     *v = max;
     if (max != 0.0)
        *s = delta / max;
     else 
          *s = 0.0;
     if (*s == 0.0) *h = noHue;
     else
     {
         if (r == max)
            *h = (g - b) / delta;
         else if (g == max)
            *h = 2 + (b - r) / delta;
         else if (b == max)
            *h = 4 + (r - g) / delta;
         *h *= 60.0;
         if (*h < 0) *h += 360.0;
         *h /= 360.0;
     }
}
</b?a:b)>

I'll leave it to you to make them work with RGB values in the range [0..255]

It would certainly appear so. In fact, they'd be even better, since they deal with WORDs instead of floats.

That'll teach me for using a 11 year old API help file..
Thanks for the better solution.

Hello,

I have written a BHO for explorer.exe.
It is working fine with Win XP but same code is not working with Windows 2003 Server.

Does anybody has any idea about this?

Regards,
Tony

I mean to say BHO Dll is not loaded when exlorer.exe is laucnched.
If you have any idea about this please let me know.

My concern is that is ther any significant difference between Win XP and Win 2003 Server with reference to BHo.

Actually, to debug this dll i have inserted a MessageBox() in every function,
For e.g.

In windows XP flow is as follows: -

When dll is registered flow is as follows: -
1) DllMain.
2) Dll Register Server.
3) Dll Main.

When you open Explorer.exe
1) Dll Main.
2) Dll GetCLassObject.
3) SetSite.

When you close Explorer.exe
1) Dll Can Unload.
2) DllMain.

But in Windows 2003 flow is as follows: -

When dll is registered flow is as follows: -

1) DllMain.
2) Dll Register Server.
3) Dll Main.

When you open Explorer.exe
No call to DLLMain.
I dont know for few unknown reason DLLMain could not be called.

Please let me know if you have still not understood the problem.
