You could probably give it a quick test by referring to this page[^].

You're welcome. Don't forget when using managed code (VC++.Net) that you cannot also use MFC classes. However there are also many useful file handlers in the System.IO namespace[^].

Hi!
When I run my application, it crashes at this line curTab->getElementFromId(i)->remove();and displays:
Unhandled exception at 0x00632175 in SlogOut3D.exe: 0xC0000005: Access violation reading location 0x00000000. When I view the Memory contents at this location 0x00632175, it has:
8b 11 8b f4 8b 8d 18 ff ff ff 8b 42 18 ff d0 3b f4 e8 3e 64 ee ff eb b1 5f 5e 5b 81 c4 e8 00 00 00 3b ec e8 2c 64 ee ff 8b ...ô...ÿÿÿ.B.ÿÐ;ôè>dîÿë±_^[.Äè...;ìè,dîÿ.
curTab is a pointer.
What is wrong with this program? How to run with out crash?
|

|

"0xC0000005: Access violation reading location 0x00000000" means you are using a NULL pointer.
So either curTab is NULL or getElementFromId(i) returns NULL. You can fix the crash by checking the curTab-pointer and the pointer returned by getElementFromId(i) before using it.

Hi all,
i draw a rectangle by CDC::Rectangle function,
CDC* pDC;
CRect rect(10,10,50,50);
pDC->Rectangle(rect);
CBrush brush;
brush.CreateSolidBrush(RGB(210,210,210));
pDC->FillRect(&rect,&brush);
before using FillRect function Rectangle boundries are visible properly but when i user FillRect to Fill color in rectangle the rectangle boundaries are not visible.
and i am insert text in this rectangle,with TextOut function i also want to set the background color of the text as same as rectangle color.
please help me for this.
thanks in advance.

You probably need to use InflateRect()[^] or similar to change the limits of your rectangle before you do the fill, in order not to overwrite the borders. As to the text I think SetBkColor()[^] will probably do it.

alternatively you could first fill the rectangle, then draw the rectangle's outline.
|
|
|
|
|
That is illogical Captain.

depends on how your rectangle is defined and what tools are available for filling.
In .NET you could easily do
Graphics.FillRectangle(...);
Graphics.DrawRectangle(...);
using the same rectangle for both, not having to insect by an amount that depends on the pen characteristics.
BTW: if it works well, it doesn't have to be logical all the time!
|
|
|
|
|
Yes, it always depends ...
I know there are some rules in Win32 about where the rectangle actually ends relative to its start point and width or height, so one has to take that into account when rendering this sort of picture. I may run some tests later to remind myself how to do it.

Hello folks!
I am using this[^] method to control the initialization order of some global objects. I have (plans for) a class that will be instantiated all around the code, all instances will be globals, i was wondering, is there maybe a way to specify that i want all instances of this class instantiated in a given segment so i don't have to use
#pragma init_seg("aseg$x", some_method);
CIWantThisInSegX whatevera;
CIWantThisInSegX whateverb;everywhere and instead i can just create the instances and they will be placed in the correct segment "automatically"? Maybe by specifying a new operator for it? If it was possible it would help a lot because it is enough to forget the init_seg part only once and havoc might get loose.
Thanks in advance for any ideas.

You'll have to use Rich Edit control for that purpose, because the edit box is not capable of showing text with different fonts.
If you are using MFC check out this[^] tutorial for the Rich Edit control.
If you are not using MFC than this[^] MSDN article could be useful for you.

I suspect you'll need to use the Attach() or AttachClipboard() method.

If you are using LoadLibrary, you don't need to link to any library.
Where does this dll come from ?
|
|
|
|
|
I have created this dll and trying to call them.
First i got this error
"Error 1 error C2664: 'GetProcAddressW' : cannot convert parameter 2 from 'const char [6]' to 'LPCWSTR' c:\Users\Indumathi\Documents\Visual Studio 2005\Projects\Win32 DLL\Win32 DLL\NestedDLL.cpp 33"
To overcome this i added
_AddFunc = (AddFunc1)GetProcAddress(hInstLibrary,Text("MyDLL"));
After adding this Text command in GetProcAddress I got this error
<b>"Error 1 error LNK2019: unresolved external symbol "public: __cdecl std::exception::exception(char const *)" (??0exception@std@@QAA@PBD@Z) referenced in function "public: __cdecl std::bad_alloc::bad_alloc(char const *)" (??0bad_alloc@std@@QAA@PBD@Z) NestedDLL.obj ">
</b>
To solve this i added .lib file in the Additional Library in Linker tab
Once did that all the error went and i got this error
"Fatal error LNK 1180 cannot open input file"
I am new to VC++ and i have no idea how to solve this.
pls. help me to solve this.
