You cannot call a class member function like you call a normal function. Either use a class object to invoke that function or make the function as a static member function.

how are you calling the function?
You need to google first, if you have "It's urgent please" mentioned in your question.

I have to define a directive depending upon the value of an expression.
For Eg:
In the following statement when I change the value of DLEVEL then the STACK value changes correctly as the value of DLEVEL is a constant.
#define DLEVEL 0
#if DLEVEL == 0
#define STACK 100
#else
#define STACK 50
#endif
printf("STACK = %d\n",STACK);
However in the following STACK value changes incorrectly when I change the value of x since the x is not a const expression.
const int x = 0;
#define DLEVEL x
#if DLEVEL == 0
#define STACK 100
#else
#define STACK 50
#endif
printf("STACK = %d\n",STACK);
Anyway to define a directive depending upon the value of an expression ?

No - macros are evaluated before the compiler even sees the code, never mind being evaluated at run-time!
To see the code after macros have been evaluated, use the /P compiler option.

yes stuart you are correct
macros gets preprocessed before expression compilation

Here are two ways that may help you:
1. delayed compile-time decision
#define STACK (STACKX==0?100:50)
...
#define STACKX 12
...
printf("STACK = %d\n",STACK);
2. run-time decision
#define STACK(x) (x==0?100:50)
printf("STACK = %d\n",STACK(12));

Reposting may not help you. Rephrasing the query to something better may help you though...

Not unless you read the guidelines[^] and rephrase your query to be in accordance with it.

REPOST! Your question asked earlier was much clear.
Actual query:

load your bitmap into a picture control or a static control and then handle the WM_LBUTTONDOWN message on that control.
You need to google first, if you have "It's urgent please" mentioned in your question.

Running Mspaint.exe is easy enough, but how are you planning on getting your image to it?

i will call it using shellexecute & give the location of the image to be opened. then it will open. but i want some more from it. i want to extract pixel coordinates when i click at a point using mouse.

Why you want to call mspaint I think its better you write it yourself.

hi, I want find out all files of the dictonary to compare existing the specific file,I used WIN32_FIND_DATA about window API,as it:
<prex>
char path[MAXPATH];
GetCurrentDirectory(MAXPATH,path)
WIN32_FIND_DATA findFileData;
findFileData.dwFileAttributes=FILE_ATTRIBUTE_DIRECTORY | FILE_ATTRIBUTE_READONLY;
HANDLE fHandle=FindFirstFile(path,&findFileData);
if(fHandle!=INVALID_HANDLE_VALUE){
do{
if(!strcmp(findFileData.cFileName,strFilename)){
if(DeleteFile(strFilename)){
MessageBox(NULL,"delete file success","UDatabase",MB_OK);
break;
}
}
}while(FindNextFile(fHandle,&findFileData));
FindClose(fHandle);
}
but it ocur exception :0xC0000005: Access violation writing location 0x00405f0c at if(fHandle!=INVALID_HANDLE_VALUE),can you help me please ,thank you !

I have checked your code, its fine and no access violation caused so far. By the way, At present your code does not check all the files available in the current directory, I changed the code like -
GetCurrentDirectory(MAX_PATH,path);
<font color='red'>strcat(path,_T("\\*.*"));</font>
WIN32_FIND_DATA findFileData;
findFileData.dwFileAttributes=FILE_ATTRIBUTE_DIRECTORY | FILE_ATTRIBUTE_READONLY;
HANDLE fHandle=FindFirstFile(path,&findFileData);
Now it compares all available files with strFilename.
Just a suggestion...

The following may or may not address your issue, but here are some things I've noticed.
Firstly the following is pointless:
fresh888888 wrote: findFileData.dwFileAttributes=FILE_ATTRIBUTE_DIRECTORY | FILE_ATTRIBUTE_READONLY;
The documentation for FindFirstFile[^] states that:
LPWIN32_FIND_DATA lpFindFileData is an out only parameter.- The search is performed strictly on the name of the file, not on any attributes such as a date or a file type (for other options, see FindFirstFileEx).
Secondly your pattern (the first parameter passed to FindFirstFile[^]) contains no wildcard. You probably mean something like this:
char path[MAXPATH];
GetCurrentDirectory(MAXPATH, path);
PathAppend(path, "*");

strcmp() is not a boolean function, thus should not be treated like one.

hi anshuman_,I have found result with the exception and known differently for between char* path="" to char path[255]="" ,thanks
<prex>
char * path="";
sprintf(path,"%s\\*",GetCurrentDirectory(MAXPATH,str));
it have error 0xC0000005: Access violation writing location
but it's right
char path[255]="";
sprintf(path,"%s\\*",GetCurrentDirectory
perfect...
char path[MAXPATH];
GetCurrentDirectory(MAXPATH,path)
WIN32_FIND_DATA findFileData;
char strFilename[255]="";
SYSTEMTIME stime;
GetLocalTime(&stime);
CString strTime="";
strTime.Format("%4d%02d%02d",stime.wYear,stime.wMonth,stime.wDay);
sprintf(strFilename,"%s\\report_invoice_%s%s.xls",path,dp->lineText,strTime);
HANDLE fHandle=FindFirstFile(strFilename,&findFileData);
if(fHandle!=INVALID_HANDLE_VALUE){
if(DeleteFile(strFilename)){
MessageBox(NULL,"删除文件成功","UDatabase",MB_OK);
}
FindClose(fHandle);
}

I confirmed that gps value changes in NMEAParserDemo Project
Did to do practice moving NMEAParserDemo Project's source to web project as it is
Value 'Ho' does not change.
