Re: using OnLButtonDown Christian Graus4-Sep-01 18:59 Christian Graus 4-Sep-01 18:59  By deriving a class from the picture control ?

Urgent:: Problem in Changing the style of ComboBox Dhanush4-Sep-01 18:15 Dhanush 4-Sep-01 18:15  Hello everybody, In a program i need to change the style of a ComboBox (Using Win32 SDK in ATL) from CBS_DROPDOWN to CBS_DROPDOWNLIST (either way). I tried using SetWindowLong() and ModifyStyle(), but failed in both the ways and failed to get what i want. If anybody knows plz help me. Even i tried with subclassing. Thanx in advance. Re: Urgent:: Problem in Changing the style of ComboBox Tomasz Sowinski5-Sep-01 2:51 Tomasz Sowinski 5-Sep-01 2:51  I think you'll have to re-create the combo - you can't change these styles at runtime. Save the control ID and position, then call DestroyWindow and Create with appropriate styles. Tomasz Sowinski -- http://www.shooltz.com About debug version and release version. Aaron03144-Sep-01 15:34 Aaron0314 4-Sep-01 15:34  I want to know why the results of debug version and release version are not identical when using VC++? (My program has no memory leak.)I set 4 level-warning in project settings,and I am sure that all the variables are initialized,but some results aren't the same slightly,for instance:"Waist=75.620499,Knee=36.650490 "in release version and "Waist=75.630901,Knee=37.181105" in debug version.I suspect if the problems consist in float type,thanks for any help.

The code generates an exception in the 2nd iteration of CHtmlView::OnSize() - so the program crashes immediately. I have a clean windows 2000 SP2 installation, visual studio 6 SP6 and IE5.5.2. Thought it might be a problem with whatever dll contains CHtmlView so I have tried reinstalling IE, etc. I'm going nuts. Anyone got any ideas? Darn Bitmap button! 4-Sep-01 11:18 4-Sep-01 11:18  Hi there, reader of this message! The problem is this piece of code. I'm using MFC and using the resource manager I've drawn a bitmap button in a dialog box and using class wiz I assigned it, the name m_button. I've put this piece of code in OnInitDialog: CBitmap bitmap; bitmap.LoadBitmap(IDB_TREE); hBitMap = (HBITMAP)bitmap; m_button.SetBitmap(hBitMap);//IDB_TREE is a 16 mil col btmap, but I tried with 256 and still doesn't work. The code compiles but there is no effect. The button is as dull as always, there is no picture upon it nor any text(shouldn't be any text). I'm sure there is a simple answer, so great computer genius, would u be so kind as pointing me to it? Many thanks and happy prog! To live in truth! Re: Darn Bitmap button! Christian Graus4-Sep-01 12:28 Christian Graus 4-Sep-01 12:28  First of all, operatorHBITMAP is defined for CBitmap, so you can pass a CBitmap where a HBITMAP is expected. I think from memory you need to set the bitmap button to be owner drawn though. I always use AutoLoad for bitmap buttons, you create the bitmaps as resources and name them with quotes like this "ImageOne" "ImageOneX" etc. Then the caption on the button needs to be "ImageOne", and you call autoload, and get up to four bitmaps loaded ( up, down, disabled, and I forget the fourth ). Look up Autoload in the MSDN, you'll probably find it's a better option. Christian As I learn the innermost secrets of the around me, they reward me in many ways to keep quiet.

Michael Dunn4-Sep-01 14:14 Michael Dunn 4-Sep-01 14:14  Your CBitmap object goes out of scope after OnInitDialog() returns, which destroys the bitmap object. Move the CBitmap object to a member variable. --Mike-- http://home.inreach.com/mdunn/ You are the weakest link, GOODBYE! Re: Darn Bitmap button! Paolo Messina5-Sep-01 0:17 Paolo Messina 5-Sep-01 0:17  Hi, Make sure the style of the button is BS_BITMAP (but I'm sure you did). Then try to use a member CBitmap variable, otherwise the bitmap is destroyed as soon as the viariable goes out of scope.

Re: Convert Problem Anders Molin4-Sep-01 9:45 Anders Molin 4-Sep-01 9:45  char buffer[10]; float fp = 12345.123 sprintf(buffer, "%f", fp); It should do the trick, take a look at sprintf() in MSDN... - Anders Money talks, but all mine ever says is "Goodbye!" Re: Convert Problem Carlos Antollini4-Sep-01 9:49 Carlos Antollini 4-Sep-01 9:49  Yes the _fcvt function. <br /> char *_fcvt(double value, int nDigits, int* ndecposition, int* sign );<br /> Cheers!!!! Carlos Antollini. Re: Convert Problem The_Server4-Sep-01 13:32 The_Server 4-Sep-01 13:32  I prefer the _gcvt the _fcvt return a static pointer, there for I think it will have problems with multi thread app. BTW: for some of you that wished for CodeProject irc server I create a channle on DalNet called "#CodeProject" Re: Convert Problem 4-Sep-01 9:54 4-Sep-01 9:54  In C (or C++) : float x = 1.56; LPSTR text; /* allocate memory for 'text' */ sprintf( text, "%f", x ); --------------------------------------- In C++ : #include <sstream> float x = 1.56; ostringstream out; out << f; string s = out.str(); // s.c_str() can be written to 'text' now --------------------------------------- Alternatively, you can look for fcvt() on your platform (Windows, I'm assuming).

Does anybody know how to do it without writing custom code? Thanks Michael Re: STL String to Number Conversion 4-Sep-01 9:58 4-Sep-01 9:58  _ecvt() can be used, though I'm not sure what platorms implement this. Windows at least does, so you're safe there. Pass in c_str() where needed. HTH Re: STL String to Number Conversion Mike Burston4-Sep-01 12:50 Mike Burston 4-Sep-01 12:50  Use std::stringstream. Something like this : std::string s = "3.4"; double d; std::stringstream ss; ss.str(s); // initialize the stream with a copy of the contents of string 's' ss >> d; // extract a double from the stream
