thx for the help done.

if you have the string-representation of the hex number, such as "F5", the you may use strtol function, e.g.
char *pEnd;
long nVal = strtol("F5", &pEnd, 16);
hope that helps.

I have following situation:
class A {...}
class B : public A {...}
can i do this:
A *a = new B;
delete a;
Thank you for reading and even more for answering

I cannot see any question marks, but since the written code isn't obviously wrong or bad the conclusion is this:
The written code is maybe ok.
Problems might occur if the base class destructor isn't declared virtual; if so, the derived class destructor will never be called and memory might leak.
|
|
|
|
|
Yes of course. Why not ?
If you want the destructor of B to be called, you need to make the destructor of A virtual (take this habbit: whenever you have a class that can be inherited, declare its destructor virtual)

Thank you for answering. It was more annoying stuff, but i didnt noticed it:
class A {...}
class B : public A, public X {...}
class C {...}
my code:
X *x = new C;
delete x; // kabooom
Well problem solved, thank you again for answering.

Hi All,
I am debugging an application(MyApp) which uses an OCX control.
I need to debug the OCX control too.
I am able to compile the OCX in debug mode and have copied the MyOcx.ocx and MyOcx.pdb files to MyApp Debug folder.
When I try to debug the MyApp I am not able to debug the OCX code. I checked with the modules window and found that the symbols for the ocx could not be loaded and it shows "" C:\WINDOWS\System.Drawing.pdb: Cannot find or open the PDB file." error
I checked with the C: files but the .pdb do not exist.
Is it a problem with my m/c that it does not have the System.Drawing.pdb file or I am wrong somewhere else?
Please help me.
Just a note to add: MyApp is built in VS2005 and MyOcx is built in VS2003.
Any help would be highly appreciated.
Thanks and Regards,
Arti Gujare

Hi Arti,
do you perhaps use the .NET Framework in your OCX? Because "System.Drawing" sounds like the corresponding namespace of the .NET Framework.
Perhaps your callstack looks nicer if you use the Microsoft Symbol Server to get the corresponding debug symbols. Then for example "System.Drawing.pdb" will be automatically downloaded from M$.
Checkout the following articles on how to configure Visual Studio to connect to the M$ Symbol Server:

cheers,

to test if the connection to your database is correct or not, you can try this SQL statement :
SELECT 1 FROM DUAL;
|
|
|
|
|
but how can i retrieve if is correct or not ?
can you give me more please ...because i need an answer into AfxMessageBox("...");

There is an application which downloads and installs a few applications on user machine after checking his machine for already installed things.
We need to parallelize this code in order to optimize its performance.
We are thinking of running one thread for downloads - one after another, and another thread for running the installs - as soon as a download is complete this thread will take over the installation.
However are there more tricks to parallelize more things - say parallelize 2 downloads?
Any other tricks to minimize CPU usage / optimize on memory usgae and reduce total time required?
Thanks in advance

If you parallelize 2 downloads you will divide the download bandwitdh by 2 ??? no ?
in consequence the download of the both files will take the same time than if you download one by one.
However I think that installing during downloading is a good idea.

There's nothing wrong with splitting work between threads, but unless you have a multi-processor machine, creating additional threads does not necessarily result in a performance gain. Most of the time it has the opposite effect (due to all of the context switches).
