In addition you also have to set the entry point symbol to wWinMainCRTStartup. This can be done in the Project->Settings menu->Link tab->Output Category->Entry-point symbol.
Also IMO, one is better off using the TCHAR macros rather then hard coding the unicode functions and string literals.

hi there, i am trying to obtain the 8-bit code for an image. I have found the edge map of an object so i now have black pixels showing the outline of the object on a white background.
I am wondering how I can extrct the bitmap code that contains the coordinates of the pixels that are black in the image.
I am using paintshop pro.
I am using a mathematical method known as the Hausdorff distance method to compare two images and recognise objects, in particular human faces.
If anyone is interested in my work I would be happy to post it on this site.
Hope someone can help me!

CString str(_T("abc"));
TCHAR* buff=str.GetBuffer(-1);
//is this okey to pass -1 to getbuffer if im not goin
//to modifiy the size the received buffer ?
|
|
|
|
|
I feel it should be
TCHAR* buff=str.GetBuffer(0);

According to MSDN, -1 is not a valid parameter. What exactly is it that you are trying to do?

How to find a DLL's Memory Usage on run-time ?
thanks in advance
|
|
|
|
|
I believe the information you are after must be tracked through the owning application since the application's stack and heap are shared by the DLL. Unless there were internal counters in place within the EXE, I know of no way to distinguish between memory allocated by the EXE vs. memory allocated by the DLL.

Why my program runs more slower when it is built in Unicode mode which is supposed to be more faster?

using unicode should not make your software faster, and should not make your software go slower either.
maybe you are spending (too much) time converting unicode strings to non-unicode strings, or vice-versa.

This is not necessarily True.
MOST of the Win32 API calls involving strings that are used by an ANSI program have to first pass through interal code to CONVERT those strings to Unicode before calling the native UNICODE functions in the WIN32 API and then back into ANSI upon returning any strings. Microsoft has consistently stated that a UNICODE application with a lot of string processing towards WIN32 API function calls would be faster if it were built to use UNICODE.
So the question makes sense, why is it slower in UNICODE?
I don't really know why.

I have a Distance Structure that includes Miles, Feet, and Inches. The user inputs these amounts 3 digits for miles, 4 digits for feed and 2 digits for inches. Not all of the time the user will input this number of digits, when the user doesn't input the full number of digits to display the output I need to back fill the numbers with zero's. Like 97 for miles would be display 097. I need some ideas on how to incorporate the back fill zero into a function. Thanks.
Thanks!

int i = 97;

Your program is trying to free (or delete) a memory location that hasn't been allocated or has already been freed.

my code here--------->
test.h
------
TEST_API void TestCStringArray(CStringArray* _testarray);
test.cpp
--------
TEST_API void TestCStringArray(CStringArray* _testarray)
{
_testarray->Add("test1");
_testarray->Add("test2");
_testarray->Add("test3");
_testarray->Add("test4");
}
============================================================
using dll code here------>
typedef void (*EXTERNAL_TESTCSTRINGARRAY) (CStringArray* _testarray);
EXTERNAL_TESTCSTRINGARRAY dll_testcstringarray;
CStringArray _testarray;
dll_testcstringarray(&_testarray);
for (int i=0;i<_testarray.GetSize();i++)
{
m_ist.AddString(_testarray.GetAt(i));
}
what i missing?
i don't know?
how can i solve this error???

Are your DLL and exe both using the same heap? If not your exe may be trying to delete a pointer on its heap which was allocated on the DLLs heap.

can u tell me about heap..(memory allocate)
i'm just small programmer.
so,i can't handle.
how can i keep?

Basically, memory allocated by a DLL should be freed by that DLL (not by your EXE). And vice-versa.

And therein lies the rub. What Roger was pointing out is exactly what's happening. When adding the CStringArray has strings added to it in the DLL, the guts of the CStrings inside the CStringArray are allocated by the DLL. But then the CStringArray goes out of scope in the application, the app tries to free it from the heap. Hence, the error 
By the way, this particular error can occur when you overflow an allocated block. Ten gallons of crap doesn't fit in a five gallon bucket (feel free to convert to liters  ).
