It's hard to say, but the server probably parses the message and notices some important SMTP header is missing. You can try catching the output of a commercial mail application and mimicking that in your program, just for testing purposes: then, carefully erasing one header at a time you'll find what the server is requiring as mandatory. Hope this helps.

hi everybody,
does anyone of you all know how to write covariance matrix and eig function in Visual C++?
or anyone of you noe any website got the Visual C++ maths function algorithm free for use?
thank you very much.

I have a question regarding scrolling on rich edit controls. I want to scroll to the bottom of the control like when you click the vertical scroll bar. I tried the linescroll func with getlincount, but it only work when I 1st start the progam. When the user uses the scroll bar, this method does not work as expected. Instead, it give me a blank page (blank page but scroll bar at bottom). Is there Cwnd function that I should used instead. Thank you for any help.

Hi, i'm trying to implement the Darkside mini SQL library in my ISAPI extension DLL. I tested the library before with a console application and it worked great, but not with my ISAPI dll... I get the following errors:

Error executing cl.exe.
Something to do with the types already defined in windef.h.. but i don't see why it says that since there's no type redefinition, just an enum, like this (dsql_m_structs.h):
class MyDate;
namespace dsqlm {
class Database;
enum boolean { FALSE=0,TRUE=1 };
enum DsqlType {SMALLINT,INT,BIGINT,FLOAT,DOUBLE,CHAR,VARCHAR,
DATE,TIME,TIMESTAMP,BOOL,AUTOID,UID};
enum ComparissonOperator {EQUALS,NOT_EQUALS,GREATER_THAN,LESSER_THAN,
GREATER_THAN_OR_EQUAL_TO,LESSER_THAN_OR_EQUAL_TO,
LIKE};
enum LogicalOperator {AND,OR};
...
Does anyone see how i could fix it? I really need the database..
Thanks

Hello,
Here is the question:
Is it possible to modify an exception inside a catch block and then rethrow it ?
Under
http://www.codeproject.com/cpp/ANSI-cpp-dec96/except.asp
the only point I see connected to this question is:
19When the handler declares a non-constant object, any changes to that
object will not affect the temporary object that was initialized by
execution of the throw-expression. When the handler declares a refer-
ence to a non-constant object, any changes to the referenced object
are changes to the temporary object initialized when the throw-expres-
sion was executed and will have effect should that object be rethrown.
But this is confusing to me because it seems that is possible to modify a
const exception while it is not possible to modify a non const exception:
which is exactly the contrary that I would expect !
like:
<br />
catch ( BasicException& e ) {<br />
e.setMessage( e->getMessage() + " some more informations here " );
throw;
}<br />
<br />
catch ( const BasicException& e ) {<br />
e.setMessage( e->getMessage() + " some more informations here " );
throw;
}
Thank you in advance for any answer
Marcello
P.S.
If it is not clear enough what I need to do, here is an example:
<br />
typedef std::basic_string<VCFChar> String;<br />
<br />
class BasicException : public std::exception {<br />
public:<br />
BasicException( const VCF::String & message ) {<br />
message_ = message;<br />
}<br />
<br />
void setMessage( const VCF::String & message ) {<br />
message_ = message;<br />
}<br />
String getMessage () {<br />
return message_;<br />
}<br />
String message_;<br />
}<br />
<br />
<br />
class A {<br />
void f() {<br />
bool error = true;<br />
if ( error ) {<br />
throw BasicException( "original message" );<br />
}<br />
}<br />
<br />
void g() {<br />
try {<br />
f();<br />
}<br />
catch ( BasicException& e ) {<br />
e.setMessage( e->getMessage() + " some more informations here " );<br />
throw;
}<br />
};<br />
<br />
int main(int argc, char *argv[])<br />
{<br />
A a;<br />
try {<br />
a.g();<br />
}<br />
catch ( BasicException& e ) {<br />
cout << e.getMessage() << endl;<br />
}<br />
}<br />

The paragraph states precisely what one would expect, i.e that non-const references to exception objects allow for modyfing and the changes will go up the stack if the object is rethrown. That is, no surprises here.
If you read it carefully, the first part says a non-constant object, as in
catch(BasicException e) and the second refers to non-constant references as in
catch(BasicException& e) In the first case, what the catch handler gets is a copy of the thrown object, exactly as when you call a regular function with signature foo(BasicExceotion e). In the second case, you get a reference to the original object and modifying can be done freely.

Now this is very clear

Looks like you forgot to actually link to the opengl libraries. Do it and the errors will go away.

Given an executable compiled using VC++ (unmanaged), is there a way to identify if the EXE is a debug or release build? Obviously, if you had the two builds side by side, the larger would be the debug, but is there a way to detect if the EXE is a debug build?
Regards
|
|
|
|
|
Well one way would be to check its DLL dependancies and if it was using the MFC/CRT Debug DLL's you'd now. There are probably better ways. 
IMO Debug .EXE's should be able to identified by their filename, in the same way Debug DLL's are.

how about
#ifdef _DEBUG
/* do something here */
#endif
is that what you were asking?
~LizardWiz()
|
|
|
|
|
No, I was looking more for something to determine if a selected EXE is a debug build or not. Not from within code, but if someone just hands you an EXE, how can I determine if it is a DEBUG build.
I think Neville answered my question...just wish there was a little easier solution. I was hoping for something more programmatic...an app I could drag and drop an EXE into or a shell extension that I could use to right click and select on an EXE in Explorer.
thanks for the response, though.

I have some code that I am having problems with. In the destructor. It is pretty straight forward:
[quote]
{
if( m_pData != NULL )
{
delete [] m_pData;
}
}
[/quote]
I am compiling and running this through MS Visual C++ 6.0. When I create a debug version, and then step through it, it fails at the delete [] m_pData line. I get the following error:
[quote]
"Debug Error!
Program: D:\MyProg\Debug\MyProg.exe
DAMAGE: after Normal block (#55) at 0x04730068.
(Press Retry to debug the application)"
[/quote]
I then hit retry, and I recieve:
[quote]
"User Breakpoint called from code at 0x40cecf"
[/quote]
The debugger is now pointing to:
[quote]
if (!CheckBytes(pbData(pHead) + pHead->nDataSize, _bNoMansLandFill, nNoMansLandSize))
_RPT3(_CRT_ERROR, "DAMAGE: after %hs block (#%d) at 0x%08X.\n",
szBlockUseName[_BLOCK_TYPE(pHead->nBlockUse)],
pHead->lRequest,
(BYTE *) pbData(pHead));
[/quote]
in VC98\CRT\SRC\DBGHEAP.C
When I switch to build a release version, I do not get this error.
What is going on, and how can I fix this.
-Drew

You need to fix the likely underlying buffer overrun.
(You don't get this error in release because the debug checks are turned off.)

This is what I was afraid of. This is code I have used before(I haven't changed anything). But it has worked fine before without this error. I have located the place where I am filling m_pData and it reads:
[quote]
m_pData = new unsigned char[bitmapInfoHeader->biSizeImage];
if( m_pData == NULL )
{
return false;
}
fread( m_pData, 1, bitmapInfoHeader->biSizeImage, fp );
fclose( fp );
[/quote]
if I change the initial line to:
m_pData = new unsigned char[bitmapInfoHeader->biSizeImage+1];
it works fine.
How is the fread reading in extra data?
Am I misunderstanding how fread works? Am I looking at the wrong part of my code, and this fixes it, but isn't really what causes the problem?
-Drew
|
|
|
|
|
It doesn't look like the fread is causing the problem. One way to verify this is to delete m_pData immediately after the fread() and see if an error is emitted.
(This is where BoundsChecker is invaluable, but its hard to convince the people with the money into getting it. I've been trying for months at my current job to no avail.)

Thanks for helping with this. I do:
delete [] m_pData;
right after the fread function. Now I am getting the following error:
"The instruction at "0x00405f3b" refereced memory at "0x04731000". The memory could not be "read"."
This is familiar, but I still can't figure out why fread is doing this. If I do the delete later after I manipulate the memory, I get the previously mentioned error. Does this prompt any ideas about what might be going on?
-Drew

Are you opening the file in binary mode?

- P.J. O'Rourke
|
|
|
|
|
Yes, I am opening it in binary. I believe it is supposed to be(this is an image file). I am using:
if( ( fp = fopen( fileName, "rb" ) ) == NULL )
{
return false;
}
I changed it to "r", and the same problem happened.
