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));

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

vvlnkishore wrote:i am trying to embed mspaint into an mfc application. in that i wanted to load a bitmap image and when i click at a position in the image with a mouse i want to read the position coordinates. is it possible ? if so please help me

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?

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... Unsure | :~

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);
