No,the thread is a work thread which only accept connections from clients and reply them.And the thread belong to a GUI window,when the window is been terminated,the exception would occur! I think the reason is that the socket remain blocking or active.

You're probably right.
Using CAsyncSocket would get you out of that trouble.
Since you're probably accessing the socket from multiple threads, there could be a problem with accessing the correct underlying handle.
How do you transfer the socket between threads?

Simply post your question and most likely someone will pick up your thread and help you.
I try to stay of the boards on weekends though and I suspect a major part feels the same way.
Have a nice weekend!

Hi all,
I have declared two enums:
enum ANICTG1 { DOG = 1, CAT = 2 };
enum ANICTG2 { LION = 1, TIGER = 2 };
ANICTG1 a1;
ANICTG2 a2;
if i get a1 value, How can i assign a1 to a2?
Whether static_cast a better way to use?
Thank you all.

In my opinion you should avoid this because it doesn't make sense.
Consider having an enum with days of the week and another with months
typedef enum
{
Sunday = 1,
Monday,
Tuesday,
Wednesday,
Thursday,
Friday,
Saturday
} Weekdays_t;
typedef enum
{
Januari = 1,
Februari,
March,
April,
May,
June,
Juli,
August,
September,
October,
November,
December
} Months_t
It wouldn't make sense to assign Januari to a weekday in my book, even if the value (1) is the same. It would be confusing for anyone that reads the code later.
If you should have some kind of mapping between two enums, I suggest you at least map it in a switch-case statement.

hi guys... can you help me with my problem?
i have this C project with its source codes... i can compile it using vs2005 and run the program... what i want is to do is to make a dll out of it since some projects are compiled as .lib and some are .exe... so i set the configuration properties>configuration type to .dll.. but i get this errors:
Error 83 error LNK2001: unresolved external symbol ___ckd_calloc__ mdef.obj
and many more of this things...
so any answers why this happens to me? thanks
|
|
|
|
|
I think so this is not complete info, can you write some more more information, as which method are you calling and what sort of log is in the output window, are you calling any function *calloc* and is mdef.c or mdef.cpp is included in your project.
Best Regards,
Mushq

Hi,
When I'm debugging my project I'm getting a access violation error like the following
Unhandled exception at 0x12bb8c3 in [exe]: 0xC0000005:
Access Violation Reading Location 0xbaadf00d
Any help on this would be highly appreciated.
Thanks

You haven't given enough information such as a stack trace and the line which causes the crash. See here[^] for a possible hint regarding 0xbaadf00d.

This is the trace that I get in Output window. Note that I'm copying the debug versions of exe and dll into my installition folder of my appplication.

A stack trace would be useful. And the source code around the problem with the line in question marked.

>>Access violation reading location 0xbaadf00d.
That still cracks me up. The first time I saw that in the debugger long ago, I thought it
was a coincidence. 
0xBAADF00D, 0xDEADC0DE, 0xDEADBEEF, etc.

0xbaadf00d is a good indication that you are trying to access heap memory that is uninitialized.

In general the best way to solve this kind of problems is to use your debugger: check where the code crashes and put breakpoints to evaluate the different variables around the crash to check if they contain what you expect.
|
|
|
|
|
I have debugged and from the stack trace it looks it that there is some problem with registeration of the coclass.
|
|
|

Does the below make any diiference :
Source File: C:\Program Files \Microsoft Visual Studio 8\VC\atlmfc\include\atlcomcli.h
Module: C:\Program Files\HP\Digital Imaging\bin\hpqtra08.exe
Process:[3828]hpqtra08.exe
The source files is different from when the module was built. Would you like the debugger to use it anyway?

Your not really giving enough information for anyone to help you. There are many possible causes for an access violation. I give the following advice about once a month; it often helps me track down the nastier heap errors:
Try enabling the page heap[^] for your process. Follow these steps:
1. Download and install WinDBG[^].
2. Select “Start”->“All Programs”->“Debugging Tools for Windows”->“Global Flags”.
3. Select the “Image File” tab.
4. In the “Image: (TAB to refresh)” edit control enter the name of your app then press TAB. Just the name with the extension; not the full path.
5. Tick the following:
- “Enable page heap”
- “Enable heap tail checking”
- “Enable heap free checking”
- “Enable heap parameter checking”
- “Enable heap validation on call”
- “Create user mode stack trace database”
6. Press “Apply”.
7. Debug your application. Any debugger will do but with WinDBG you have access to the stack traces of allocations via the !heap –p –a command, for example. When a heap problem is detected a breakpoint will be generated.
8. When done un-tick all the options you ticked, press “Apply” then dismiss GFlags. This step is important as if it’s skipped all applications named as entered in step 4 will run with the page heap enabled.
Note that when using the page heap your application will run much slower than normal and consume way more memory. It’s good to have a beefy machine to do such tests; and such tests should be ran regularly on all applications you develop as part of regular testing activities. If I find a part of my application that’s too slow with the page heap enabled I optimize the memory allocation in that region.

Hi,
I have a piece of hardware that I want to integrate with Office Commnicator 2007. Could somebody point to me where can I get the API/SDK for OC2007? I want to integrate the OC2007 functionality into my app by launching portions of OC2007 user interface, such as the phone dialer...
