Command enablers don't get called for dialogs by default.
You can enable them by adding a handler for the undocumented
WM_KICKIDLE message, something like this:
ON_MESSAGE(WM_KICKIDLE,&CMyDlg::OnKickIdle)
...
LRESULT CMyDlg::OnKickIdle(WPARAM wp, LPARAM lp)
{
UpdateDialogControls(this, TRUE);
return 0;
}

In general, (not just what you said here) using the undocumented functions, is ideal?
Could you please share your opinion regarding this?
|
|
|
|
|
I personally don't use undocumented system messages or functions.
In this case, it's part of MFC, which we all have the source code for.
WM_KICKIDLE has been around a long time and it's pretty unlikely it will
go away. Maybe they'll even document it some day

When I compiled the following very simple "c" code in Release mode, VC++ 6.0 compiler is giving the INTERNAL COMPILER ERROR error. Can anybody tell me why this happens.
/*test.c*/
void main()
{
__int64 a=0, b=0;
do
{
int c = a-b ? a-b : 0;
b = c;
}while(b);
}
Thanks
Shino

Do you get any different result if you change the file's extension to CPP?

No problem. But still compiler is showing the same error.
|
|
|
|
|
What compiler are you using? Other than a C4244 warning, I compiled it just fine with VS6. Have you read this?

Do you have the latest visual C++ 6.0 service pack installed? The latest one is Service pack 6. You could find it here[^].

i need convert image bitmap 8bits to image bitmap 24bits or convert image bitmap 8bits to file pcl. thanks very much
|
|
|
|
|
To convert from 8-bits to 24-bits simple copy the value from 8-bit image to all 3 channels in the 24-bits image.

Are you sure?

Yes, why? Would you do it any other way?

8 bitimages are normally having a color palette where the actual color is stored. And the index to that color array is stored as pixel info (that is the 8bit).
|
|
|
|
|
don't know. can you tell specific ?
|
|
|
|
|
can you tell technical raster when process image bitmap 8bits ?
|
|
|

In general, for 8 bit images there will be a color palette. And each pixel is stored as 8 bit data. But it will not be the actual color. Instead it will be an index of the color palette. Since one pixel is stored with 8 bit data, there can be a maximum of 256 colors. The color palette is having the RGB info of these 256 colors.
Hope it is clear to you.
I am not sure about typical monochrome images.
Like the 8 bit image there are 4 bit images also. In that the pixel is stored with 4 bit pixel info and it is the index of the color palette of maximum of 16 colors.

that only works if the 8-bit image is grayscale.

can you tell specific ? are you there are documents for it ?

Hello, I have a weired problem...
I have a CTime object called t and my fuction supposed to add one day to this object, it works perfectly until it gets to the date "October 5th 2008" (5/10/2008) and then it is giving me the same date (without adding it one day)
Here is the code (t is the date we want to enlarge)
CTimeSpan ts (1,0,0,0);
CTime t2= t + ts;
return t2;
