I saw ur article.It was nice.But its something similar to that.I'm following doc-view architecture for my project.When i change the language settings the view needs to be updated with the language settings......But if i refresh the view its not happening and error is raised in RELEASE version.

I would say it is unlikely any internationalisation code would raise an error, unless of course the resource IDs are not consistent between languages, possibly an ID for a control has been swopped for a string resource.
As a test I would suggest you copy your default language resources to a new language, i.e. English to French, but do NOT change any of the resouces. Run a test changing the language to French is you don't get an exception then check your resource IDs. If you still get an exception then the error is elsewhere.
Hope this helps. Ahh I do remember a bug in Visual C++ I think it was V 6.0 but fixed on sp3 or sp4, but that did not cause an exception, just the language would not change.

Intel is no longer offering its IJL jpeg library.
Where i could download it ? Anyone has it, could send it to me ? 
|
|
|
|
|
 search for IJL in google and you will see many options where you can find IJL. I guess it is also available at intel's site. all the best.

How can I write a Program in Visual C, that takes over the Desktop and Mouse-Functions of another
Windows-NT PC in a LAN/WAN (like SMS, or pcAnywhere it does) ?.
Is there an API available, or an example ?
Who knows the answer ??

Well, I'm hoping you're thinking of remote administration, rather than nasty hacker stuff, but the source code to VNC is freely available http://www.realvnc.com[^] though, tbh, if you just want a free and simple remote admin/control system then I don't see why you'd need to actually modify VNC at all - it works brilliantly as it is

dear all,
i get a warning
D:\Schd\Config.cpp(117) : warning C4172: returning address of local variable or temporary
when i compile this code:-
char *CConfig::InputFilePath ()
{
char *inp;
** inp = new char[MAXCHARS];
int i= GetPrivateProfileString("Paths", "inputfile", "" ,inp, MAXCHARS, IniPath);
CString path(inp);
char filename[11];
int ch = 92;
unsigned int result;
char *pdest;
char iPath[MAXCHARS];
try
{
if ( (path == "") || CConfig::DoesDirectoryExist (inp) == false )
{
path = "";
strcpy(iPath,"");
return iPath;
}
pdest = strrchr( path, ch );
result = pdest - path + 1;
if ( result == strlen(path) )
{
strcpy(filename,"Input.con");
}
else
{
strcpy(filename,"\\Input.con");
}
strcpy(inp,path);
strcpy(inp, strncat( inp, filename,strlen(filename)));
}
catch(...)
{
path = "";
strcpy(iPath,"");
return iPath;
/*strcpy(filename,"\\Input.con");
strcpy(inp, strncat(_getcwd( buffer, _MAX_PATH), filename,strlen(filename)));*/
}
strcpy(iPath,inp);
delete [] inp;
return iPath;
}
also sometimes i get warning :-
detected memory leaks,
Object dump complete,
at location ** in the code
can anyone suggest some solutions! 
thanx,

char *CConfig::InputFilePath ()
{
...
char iPath[MAXCHARS];
...
return iPath;
}The problem is very accurately described by the warning you're having. iPath gets destroyed as soon as InputFilePath exits, so returning its address is illegal. The simplest solution, probably, is to return a CString:
CString CConfig::InputFilePath ()
{
...
char iPath[MAXCHARS];
...
return iPath;
}Even if this fix works, I'd strongly suggest that you try to fully understand why your problem was happening, since it is a common error in beginners and something similar could shoot you in the future when least expected.

thanx for the TIP Joaquín!
i'll keep it in mind and'll try to stick to it!
but is there anyother way to get rid if the specified scenario!
also can u help me with the memory leak while i'm deleting the pointer inp.
thanx a ton! ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

** inp = new char[MAXCHARS]; should be
inp = new char[MAXCHARS]; I'm surprised that the code even compiled

sorry, but u misread my first thread.
** was to imply that THIS line of code gives memory leak warning! (** acted like a label in my thread, thats it!)

dear all,
the code (in Bold) generates a memory leak and i get a warning, Object dump complete
char *CConfig::InputFilePath ()
{
char *inp;
inp = new char[MAXCHARS]; /*??Memory Leak, but it is deleted later in the code */
int i= GetPrivateProfileString("Paths", "inputfile", "" ,inp, MAXCHARS, IniPath);
CString path(inp);
char filename[11];
int ch = 92;
unsigned int result;
char *pdest;
char iPath[MAXCHARS];
try
{
if ( (path == "") || CConfig::DoesDirectoryExist (inp) == false )
{
path = "";
strcpy(iPath,"");
return iPath;
}
pdest = strrchr( path, ch );
result = pdest - path + 1;
if ( result == strlen(path) )
{
strcpy(filename,"Input.con");
}
else
{
strcpy(filename,"\\Input.con");
}
strcpy(inp,path);
strcpy(inp, strncat( inp, filename,strlen(filename)));
}
catch(...)
{
path = "";
strcpy(iPath,"");
return iPath;
}
strcpy(iPath,inp);
delete [] inp;
return iPath;
}
can someone tell me why this leak is occurring and how to prevent it!
thanx

You need to look at the possibility of the function exiting before delete is called. From your code it looks like if an exception is thrown that's what happens; you catch it, and then return without freeing inp.
You may want to consider not allocating inp dynamically since it's always got a constant size (MAXCHARS).
char inp[MAXCHARS];
Another alternative is to dynamically allocate it, but on the stack using alloca:
char* inp = (char*)alloca(MAXCHARS);
Then you don't need to worry about explicitly freeing it since it will happen automatically.

You should look at your routine, and, before EVERY return, you should delete []inp.
You have 3 return points on your routine.
That's why some people advocate that routines should be structured so they have only one point of return. I'm not so rigid at this rule, but surely C++ beginners can benefit from writing routines with only one return point.
I see dumb people

I agree. A single return is one of the rules I would stick to as a new programmer. After you have been programming for many years, you learn how to safely break the rules such as "single return" or "no goto".

an example (but i can't remember its name) in msdn (first lesson about MFC) tells exactly what u need.
the example includes several steps, about using collections and how to save and open data.

if I Have DLL File And I want to use it in my project ...
How I Can Know How many function in this DLL File ,
what are They ? and What are the parameter for each Function in it and data type of them ?
Many Many Thanx for response

open the dll as buffer, the info u need can be viewed from that buffer.
i don't know format of a dll file, but i did it before: as u want to know now.
note: the buffer is in a byte file (including zero in middle), but function's info is in asc ii format.
possile need no more than 1 day to go.

1st thank u very much
I wrote the following code to read dll :
(vb code )
dim b as byte
dim c as string*1
open "xx.dll" for random as #1 len=len(b)
open "xx.txt" for random as #2 len=len(c)
while not eof(1)
get #1,,b
c=chr(b)
put #2,,c
wend
close 1
close 2
then I opened xx.txt file to discovering this dll
i read name of functions but the file is not in text format there are symbols blanks ... try this code
it's no help me
suggest ...

I have the following class
class DynamicArray {
private:
int* m_pInts;
public:
DynamicArray(int elements) {
m_pInts = new int[elements];
}
~DynamicArray() {
delete [] m_pInts;
}
};
This class creates an dynamically sized array of ints.
I also have the following function
DynamicArray GetDynamicArray() {
DynamicArray temp(89);
return temp;
}
unfourtunatly the destructor is called (on temp) when the function returns, which deletes my array of ints.
example:
int main() {
DynamicArray myArray = GetDynamicArray();
}
How do I make this work?

a) implement a copy ctor (the dtor will be still called for your local instance after it has been copied)
-or-
b) don't use local instance of your class, use a reference
void CreateMyDynamicArray(DynamicArray& ref) { ref.Create(89); }
Last line assumes you have an empty default ctor and a Create(int size) method.
PS: I suggest using a container (e.g. std::vector) instead of pointer/new/delete

I agree with moak. Use std::vector and be done with it. To see the std::vector and dynamic data array in action, take a look @ my article and demo project, CDataFile[^].
