Forget class wizard. With VC++ you would have got the MSDN cds.
Run that, and search for NM_DBLCK, etc, and get the full info there.
Or on the wab: NM_DBLCLK[^].

can you use directx? if so, use the D3DXDrawText() function
If it's broken, I probably did it

I'm programming an activeX control and my 'OnDraw' function uses both gdiplus and standard gdi calls.
When I insert my control into a dialog ressource in VC++, it is drawn correctly, but when I run the application there 's no gdiplus drawing anymore on the dialog, only gdi drawing are visible.
May someone help me?
thanks

|

I'm no expert on GDI+, but have you remembered your GdiplusStartup / GdiplusShutdown functions?
Iain.

I solved the problem :
Strangly, If the pen I am using to draw is instanciated before the GdiplusStartUp, there is no error, but the drawing are invisible with this pen...
So I declare my pen after GdiplusStartUp now.

Hi,
I intend to add voice recognition features to an application I'm developing in Visual C++. I'm comfortable in c++ and MFC and had planned to do research into the Microsoft Speech SDK 5.2 but I'm finding msdn has very little info on the Speech SDK.
Can anyone tell me if the Speech SDK has now been superseded by the SASDK, which appears to be ASP.net based.
Bearing in mind I've never touched ASP could anyone advise me where I need to focus my attention? I don't need dictation capabilities, purely command recognition.
Thanks in advance,
Simon

I'll bet you're familiar with this problem.
printf("this might crash: %s", integervalue);
In code with thousands of string formatting statements, at least some of them might be malformed.
Anyone has a solid solution to prevent this type of crash?
anyone seen good and secured string formatter code?
greetings,
Niko

USE sprintf rather than printf.
|
|
|
|
|
hmm.
this will crash too.
The question is not:
how can I format strings.
but
how can I prevent myself from crashes due to bad formatting parameters.
|
|
|
|
|
Your answer is innoportune. Are you sure you have read NikoTanghe's question ? He obviously used printf as an general example to illustrate the problem. This applies to sprintf, CString::Format, etc. as well.

The standard libraries IOStream libraries. That's what exactly what they're designed for.
int i = 1;
std::string s = "foo"
std::cout << i << s;
or in the case of printing to a buffer use std::ostringstream in preference to sprintf

As much as I dislike iostreams, I have to agree with Andrew. If the programmers can't get their formats straight then iostreams is an excellent choice.
Then again, if your programmers can't get their formats straight, you are going to have much more problems than just printing.

I'm going to patent thought. I have yet to see any prior art.

Try Boost format library. It provides type-safe formatting very similar to printf .

this can't be correct if intergervalue is effectively an integer...
%s is waiting for a char pointer which represent a NULL-terminated C-style string....
to prevent this type of crash as you say, it is first to well name your variables. iValue for an integer for example, pcArray for a char pointer...
the second thing is to be attentive when coding
or you use cout instead, but that'll be more difficult to catch error...

As a summary of what the others have written... using printf or its variants, how to prevent a crash if the wrong format specifier is used? The answer is simple:
You can't.
You will have to use IOStreams, or possibly as another person mentioned, boost. Using iostreams is probably the simplest alternate option. Either that, or make sure your format specifiers always match the data types!

See the CHARFORMAT2 structure and the EM_SETCHARFORMAT message in MSDN.
Best regards,
Dominik
CHARFORMAT2
[This is preliminary documentation and subject to change.]
The CHARFORMAT2 structure contains information about character formatting in a rich edit control. CHARFORMAT2 is a rich edit 2.0 extension of the CHARFORMAT structure. Rich edit 2.0 allows you to use either structure with the EM_GETCHARFORMAT and EM_SETCHARFORMAT messages.
typedef struct _charformat2 {
UINT cbSize;
_WPAD _wPad1;
DWORD dwMask;
DWORD dwEffects;
LONG yHeight;
LONG yOffset;
COLORREF crTextColor;
BYTE bCharSet;
BYTE bPitchAndFamily;
WCHAR szFaceName[LF_FACESIZE];
_WPAD _wPad2;
WORD wWeight;
SHORT sSpacing;
COLORREF crBackColor;
LCID lcid;
DWORD dwReserved;
SHORT sStyle;
WORD wKerning;
BYTE bUnderlineType;
BYTE bAnimation;
BYTE bRevAuthor;
BYTE bReserved1;
} CHARFORMAT2;
Members
cbSize
Specifies the size, in bytes, of this structure. Before passing this structure to a rich edit control, set cbSize to the size of the CHARFORMAT or CHARFORMAT2 structure. If cbSize equals the size of a CHARFORMAT structure, the control uses only the CHARFORMAT members.
dwMask
Specifies the parts of the CHARFORMAT2 structure that contain valid information. The dwMask member can be a combination of the values from two sets of bit flags. One set indicates the structure members that are valid. Another set indicates the valid attributes in the dwEffects member.
Set the following values to indicate the valid structure members. Value Meaning
CFM_ANIMATION The bAnimation member is valid.
CFM_BACKCOLOR The crBackColor member is valid.
CFM_CHARSET The bCharSet member is valid.
CFM_COLOR The crTextColor member is valid unless the CFE_AUTOCOLOR flag is set in the dwEffects member.
CFM_FACE The szFaceName member is valid.
CFM_KERNING The wKerning member is valid.
CFM_LCID The lcid member is valid.
CFM_OFFSET The yOffset member is valid.
CFM_REVAUTHOR The bRevAuthor member is valid.
CFM_SIZE The yHeight member is valid.
CFM_SPACING The sSpacing member is valid.
CFM_STYLE The sStyle member is valid.
CFM_UNDERLINETYPE The bUnderlineType member is valid.
CFM_WEIGHT The wWeight member is valid.
Set the following values to indicate the valid attributes of the dwEffects member: Value Meaning
CFM_ALLCAPS The CFE_ALLCAPS value is valid.
CFM_BOLD The CFE_BOLD value is valid.
CFM_COLOR The CFE_AUTOCOLOR value is valid, or the crTextColor member is valid.
CFM_DISABLED The CFE_DISABLED value is valid.
CFM_EMBOSS The CFE_EMBOSS value is valid.
CFM_HIDDEN The CFE_HIDDEN value is valid.
CFM_IMPRINT The CFE_IMPRINT value is valid.
CFM_ITALIC The CFE_ITALIC value is valid.
CFM_LINK The CFE_LINK value is valid.
CFM_OUTLINE The CFE_OUTLINE value is valid.
CFM_PROTECTED The CFE_PROTECTED value is valid.
CFM_REVISED The CFE_REVISION value is valid.
CFM_SHADOW The CFE_SHADOW value is valid.
CFM_SMALLCAPS The CFE_SMALLCAPS value is valid.
CFM_STRIKEOUT The CFE_STRIKEOUT value is valid.
CFM_SUBSCRIPT The CFE_SUBSCRIPT and CFE_SUPERSCRIPT values are valid.
CFM_SUPERSCRIPT Same as CFM_SUBSCRIPT.
CFM_UNDERLINE. The CFE_UNDERLINE value is valid.
dwEffects
A set of bit flags that specify character effects. Some of the flags are included only for compatibility with Microsoft Text Object Model (TOM) interfaces; the rich edit control stores the value but does not use it to display text.
This member can be a combination of the following values. Value Meaning
CFE_ALLCAPS Characters are all capital letters. Does not affect the way the control displays the text.
CFE_AUTOCOLOR The text color is the return value ofGetSysColor (COLOR_WINDOWTEXT). If this flag is set, the crTextColor member is ignored.
CFE_BOLD Characters are bold.
CFE_DELETED Marks the characters as deleted.
CFE_EMBOSS Characters are embossed. Does not affect how the control displays the text.
CFE_HIDDEN Characters are not displayed. Does not affect how the control displays the text.
CFE_IMPRINT Characters are displayed as imprinted characters. Does not affect how the control displays the text.
CFE_ITALIC Characters are italic.
CFE_LINK A rich edit control can send EN_LINK notification messages when it receives mouse messages while the mouse pointer is over text with the CFE_LINK effect.
CFE_OUTLINE Characters are displayed as outlined characters. Does not affect how the control displays the text.
CFE_PROTECTED Characters are protected; an attempt to modify them will cause an EN_PROTECTED notification message.
CFE_REVISION Marks the characters as revised.
CFE_SHADOW Characters are displayed as shadowed characters. Does not affect how the control displays the text.
CFE_SMALLCAPS Characters are in small capital letters. Does not affect how the control displays the text.
CFE_STRIKEOUT Characters are struck out.
CFE_SUBSCRIPT Characters are subscript. The CFE_SUPERSCRIPT and CFE_SUBSCRIPT values are mutually exclusive. For both values, the control automatically calculates an offset and a smaller font size. Alternatively, you can use the yHeight and yOffset members to explicitly specify font size and offset for subscript and superscript characters.
CFE_SUPERSCRIPT Characters are superscript.
CFE_UNDERLINE Characters are underlined.
yHeight
Specifies the character height, in twips. A twip is 1/1440 of an inch, or 1/20 of a printer's point. To use this member, set the CFM_SIZE flag in the dwMask member.
yOffset
Specifies the character offset, in twips, from the baseline. If this member is positive, the character is a superscript; if it is negative, the character is a subscript. To use this member, set the CFM_OFFSET flag in the dwMask member.
crTextColor
Specifies the text color. To use this member, set the CFM_COLOR flag in the dwMask member. This member is ignored if the CFE_AUTOCOLOR character effect is specified.
bCharSet
Specifies the character set value, which can be one of the values specified for the lfCharSet member of theLOGFONT structure. To use this member, set the CFM_CHARSET flag in the dwMask member.
bPitchAndFamily
Specifies the font family and pitch. This member is the same as the lfPitchAndFamily member of the LOGFONT structure.
szFaceName
A null-terminated character array specifying the font face name. To use this member, set the CFM_FACE flag in the dwMask member.
wWeight
Specifies the font weight. This member is the same as the lfWeight member of the LOGFONT structure. To use this member, set the CFM_WEIGHT flag in the dwMask member.
sSpacing
Specifies the horizontal space, in twips, between letters. This value has no effect on the text displayed by a rich edit control; it is included for compatibility with Microsoft Text Object Model (TOM) interfaces. To use this member, set the CFM_SPACING flag in the dwMask member.
crBackColor
Specifies the background color. To use this member, set the CFM_BACKCOLOR flag in the dwMask member.
lcid
Specifies a 32-bit locale identifier that contains a language identifier in the lower word, and a sorting identifier and reserved value in the upper word. This member has no effect on the text displayed by a rich edit control, but spelling and grammar checkers can use it to deal with language-dependent problems. You can use theMAKELCID macro to create an LCID value. To use this member, set the CFM_LCID flag in the dwMask member.
dwReserved
Reserved; must be zero.
sStyle
Specifies a style handle. This value has no effect on the text displayed by a rich edit control; it is included for compatibility with Microsoft Text Object Model (TOM) interfaces. To use this member, set the CFM_STYLE flag in the dwMask member.
wKerning
Specifies the twip size above which to kern the character. This value has no effect on the text displayed by a rich edit control; it is included for compatibility with TOM interfaces. To use this member, set the CFM_KERNING flag in the dwMask member.
bUnderlineType
Specifies the underline type. To use this member, set the CFM_UNDERLINETYPE flag in the dwMask member. This member can be one of the following values. Value Meaning
CFU_CF1UNDERLINE Map CHARFORMAT's bit underline to CHARFORMAT2.
CFU_INVERT For IME composition fake a selection.
CFU_UNDERLINE Solid underline.
CFU_UNDERLINEDOTTED Dotted underlined text. The rich edit control displays the text with a solid underline.
CFU_UNDERLINEDOUBLE Double-underlined text. The rich edit control displays the text with a solid underline.
CFU_UNDERLINENONE No underline. This is the default.
CFU_UNDERLINEWORD Underline words only. The rich edit control displays the text with a solid underline.
bAnimation
Specifies the text animation. This value has no effect on the text displayed by a rich edit control; it is included for compatibility with TOM interfaces. To use this member, set the CFM_ANIMATION flag in the dwMask member.
bRevAuthor
Specifies an index that identifies the author making a revision. The rich edit control uses different text colors for each different author index. To use this member, set the CFM_REVAUTHOR flag in the dwMask member.
bReserved1
Reserved; must be zero.

I'm trying to make a listview whith these properties:
when an item is inserted, the background is colored. you can select the "new" items and "clear" them, which recolors the item background to white. I've been reading posts and articles on doing this via CustomDraw or OwnerDraw, but i'm still confused about how to tell those functions which selected row(s) to change, and havnee't had luck getting them to jsut plain work either. I've been searchign through msdn, codeguru and code project for a solution, but so far I havne't gotten one.
I'm also implementing a custom listview for sorting, and class for dialog resize. Perhaps this is part of my problem, perhaps not.
If anyone has a custom ListView, or sample code, can you please point me in the right direction
Thanks for any help.

Is it possible to split the mainframe of a mDI application even if no document is opened ?
Thanks for your reply
Erick Girard

I dunno for sure offhand - try to Overload OnCreateClient in MainFrm instead of the Child frame. You may not be able to let the DocumentTemplate manage it, you would most likely have to manage the details yourself - after which it may not be considered an MDI app.
