Hi dudes,
I would like to know what is function for checking the given input is Integer or float or char or keys like backspace, space enter.
Thanks in Advance.

And how do you want check float by one symbol ?

I'm not sure exactly what you are asking, so I'll hypothesize and suggest functions like isdigit(), isalpha() and iswhite(). If I'm way off the mark, please rephrase what it is you are trying to do.

How would I go about retrieving the default dialog background color?

Use GetPixel(...) function to get RGB value of Dialog box

See GetSysColor(). On non-XP and non-themed XP systems I think you can use COLOR_3DFACE.

Hi
Could anyone please point to me a good tutorial and source code for C++ implementation for adaptive arithmetic encoding.
I have gone through Nelsons tutorial and few others. The implementation is bit difficult for me to understand.
Thanks in advance

Does anyone know where to find the solution to the exercise presented in the book, besides the companion book C++ Solutions.
Thanks

I'm trying to use CBitmap to manipulate a bitmap, but there's no easy way for me to extract a color from a bitmap (like GetPixel(x, y) in CWnd-derived classes). Is there something I'm missing? Suggestions are well appreciated. Alternatively, is there a way to fill a bitmap with one color like FillRect() does with DCs?
thanks,
augy

Hey,
Try this.
CDC *pDC = this->GetDC();
CDC mDC;
mDC.CreateCompatibleDC(pDC);
mDC.LoadBitmap(IDB_BITMAP1);
Now you can used GetPixel() to extract color of bitmap.
mDC.GetPixel(...);
this->ReleaseDC(pDC);
Hope this will work.

To work with a bitmap, you need to select it into a DC. The other way is to use a DIBSEction, then you can access the bits directly. Get/SetPixel are incredibly slow.

hi all
I got the text from the popupmenu item using GetMenuString like so:
TCHAR itemText[MAX_PATH] = {0};
GetMenuString(m_hList,i,itemText,MAX_PATH,MF_BYPOSITION);
then i try to find if certain sequence is in the itemText like so:
TCHAR strTOSearch[2]="(";
if(_tcsstr(itemText,strToSearch)!=NULL)
{
....
}
now if the strToSearch does not contain any white space, it works fine, but then strToSearch[4]="h h";
then it won't find the string even though itemText does contain "h h",
what am I missing?
thx

I did not used TCHAR yet. I did a simple test with strstr() and it worked.
<br />
char tst[50];<br />
strcpy(tst,"Hello you!\nThis works!");
if (strstr(tst,"lo y"))
m_output="OK";<br />
<br />
UpdateData(FALSE);<br />
The str-functions are pretty old and are not very object orientated but they don't let you down. I like them.

strstr and _tcsstr both works fine in ur case, I guess it's just my itemText from teh GetMenuString call, it's supposed to be LPTSTR, but I use TCHAR, then _tcsstr or strstr will cast it to char * in fact, const unsigned short * in the function, I guess that's why it does work.
but not sure how get cast them correctly.

The best solution would be to use CString. It has many constructors. For LPCTSTR you can use CString::CString( LPCTSTR lpch, int nLength ) and for searching a substring or a character Value in another String use CString::CString::Find(...). Just check the CString class and you will see. If it still not work than look at the return value of GetMenuString. Maybe it redrives not the whole string (don't think so).

GetMenuString return the full text, I will give it a try. thx

OK, What's going on here.
I have a C++/MFC application, and happily starts consuming memory slowly. Then when I hit the minimize box on the application, *poof*, all the memory that the application is consuming goes way down. Bring it back up, and it starts munching again slowly, minimize it, and the memory utilization goes down!
What's going on when I minimize an application?

That appears to be standard behaviour. I just tried it with Windows Task Manager where I watched the memory usage of various apps. Every one of them reduced the memory usage when they were minimized. I do not know what happens to the memory, maybe windows automatically writes it to the swap file, or Task Manager looses track of it?
Whatever it is, I wouldn't worry about it unless your app is somehow loosing data.

It's by design. Windows is trimming the working set of the application. See KB article 293215[^] for an explanantion (and some code to prevent it, should that be necessary).
