hi Arends,
i download the new version of platform SDK.
and i include those files in my tools->options->directory
as C:\program files\Microsoft SDK\Include
but now also it get some errors

The fact that ULONG_PTR is undeclared is your first clue. It means that your compiler is still using the old version of BaseTsd.h. What you have to do is move the PSDK include directory to the top of the list of directories. You probably added it to the bottom of the list. The compiler searches the directories listed from the top to the bottom.
Do the same with the lib files, you do not want your program linking to the old lib files.

Hi there,
I am using a code in VC++ (Console Win32 Application) used to connect to MYSQL. This was a successful attempt So what I think is no problem with library includes but as I tried the same code with MFC (Dialog based Application ) it returned the following linker errors:

DlgAddUser.obj : error LNK2001: unresolved external symbol _mysql_close@4

Please help me in this regard as soon as possible.

Have you added the LibMySQL.lib file to your list of libraries to be linked to your project? Try placing this in your file:
#include "MySql.h"
#pragma comment(lib, "LibMySQL.lib") It's been a while since I have played with MySQL, so I may be off base here.

I'm novice at GDI programming.
I've been working on the program which caputres the screen and saves it as a Jpeg image.
I made it. However It is really inefficient, I thought.
here is my work flow.
1. Get compatible screen DC.
2. Get compatible bitmap on it.
3. Write Bmp header and body using bitmap above.
4. Convert the bmp to Jpeg.
5. Delete bmp file.
What I mostly want to know is..
Should I make bmp file to get Jpeg image?
Could you recommend better way?
thanks.

When we create multiple desktops using CreateDesktop, I want to hook the the Start->LogOff button and shutdown the desktops gracefully rather than logging out. Any idea how we can hook the Logoff button?
thanks!

Does the SetEvent function queue events? For example, if I signal the event 10 times in a row, will a waiting thread wakeup from a waitforsingleobject 10 times? The event is setup as automatic.
Thanks in Advance...
|
|
|
|
|
No the thread will wakeup in the first time itself. the significance of a singal is in waiting state only.
Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.
|
|
|
|
|
No, SetEvent just sets the event to the signalled state, so the number of times you call SetEvent doesn't matter.

Senthil

I have a set of menus in MyFrame, and for some reason I move the
ON_COMMAND()
ON_UPDATE_COMMAND_UI()
of one of them to another module. The problem is its menu item is automatically enabled initially. All the other menu item's message map local to the MyFrame are disabled. How can the previous menu item be disabled?
Here's what MSDN says about update handler
If the framework does not find an ON_UPDATE_COMMAND_UI entry during command routing, it automatically enables the user-interface object if there is an ON_COMMAND entry somewhere with the same command ID. Otherwise, it disables the user-interface object. Therefore, to ensure that a user-interface object is enabled, supply a handler for the command the object generates or supply an update handler for it.
It is possible to disable the default disabling of user-interface objects. For more information, see the m_bAutoMenuEnable member of class CFrameWnd.
So I guess initially the Framwork doesn't find the specific ON_UPDATE_COMMAND_UI macro in MyFrame, that menu item was enabled. And I tried m_bAutoMenuEnable, that doen't work either.

The tooltips of slider control is the current positon if you set the "Tooltips" property True. How can I set a special tooltips of a slider control? Just like "The current positon: 13". Thank you!

Hello,
I've created a subclass of the Button class and I can't figure out why my OnPaintBackground method never gets called. Have any of you ever encountered this problem?

I figured it out:
this->SetStyle(ControlStyles::Opaque, false);
Just FYI...

I know XML Docs are supported for C# is VS.NET but what about C++? If XML Docs aren't supported natively for C++, has anyone come out with an add-on that implements them?

Let say I've written a MMO server. Then I write a small C++ class called Bot that emulates a typical client session. Next I write a small test harness which can launch instances of Bots in separate threads.
The questions is how can I determine the max viable number of bot threads for a given machine? Every machine will have a different CPU/RAM configuartion etc. Can I determine at run-time how many bot threads to launch? I've tested my app with 500 bots and it works fine. I crank it up to 1000 bots and my system comes to a crawl.

good afternoon, could anyone see where is the leak from? thank you! I've checked the momory allocation, the leak is happening around here:
strcpy( FileName, BinPath );
strcat( FileName, "CALLSM" );
strcat( FileName, Cycle);
strcat( FileName, ".BIN" );
if ( _access ( FileName, 0 ) != 0 )
{
sprintf( ErrorText, "File does not exist -> %s", FileName );
Message( ErrorText, VD_ERROR );
return 0;
}
m_information_line = "Loading CALLSUM Binary File.";
PostUpdate();
CallSumBin = new CALLSUM_BIN( FileName );
if ( !CallSumBin )
{
Message( "Unable to allocate CallSumBin binfile.", VD_ERROR );
return 0;
}
here is the delete in closedown() function:
if ( CallSumBin )
{
if ( !IsStop() ) {
strcpy( FileName, BinPath );
strcat( FileName, "CALLSM" );
strcat( FileName, Cycle);
strcat( FileName, ".BIN" );
m_information_line = "Saving updated CALLSM binary file";
PostUpdate();
CallSumBin->Save( FileName );
fprintf( Report,"Updated CALLSM binary file saved.\r\n" );
}
delete CallSumBin;
}
m_information_line = " ";
PostUpdate();

Where is Filename allocated ? Is it ever deleted ?
C style string handling is a messy pile of crap, and the perfect way to get memory leaks. Why are you not using C++ here ?

As far as I can see, the memory leak must be in the CALLSUM_BIN class.
|
|
|
|

i don't see any here...
you CallSumBin = new CALLSUM_BIN( FileName ); and always delete CallSumBin; it then...
so, you might have a look at the CALLSUM_BIN constructor... does it allocate some memory that is not deleted (at the end of the constructor or in the destructor ?

Is your code perhaps calling the function containing
CallSumBin = new CALLSUM_BIN( FileName );
more than once without having called the closedown() function?
If so, that will cause a memory leak. I would suggest the following:
if ( _access ( FileName, 0 ) != 0 )<br />
{<br />
sprintf( ErrorText, "File does not exist -> %s", FileName );<br />
Message( ErrorText, VD_ERROR );<br />
return 0;<br />
}<br />
m_information_line = "Loading CALLSUM Binary File.";<br />
PostUpdate();<br />
if (CallSumBin != NULL)<br />
{<br />
delete CallSumBin;<br />
CallSumBin = NULL;<br />
}<br />
CallSumBin = new CALLSUM_BIN( FileName );<br />
if ( !CallSumBin )<br />
{<br />
Message( "Unable to allocate CallSumBin binfile.", VD_ERROR );<br />
return 0;<br />
}

As krmed already stated, make sure your allocation routine isn't being called multiple times. However, I wouldn't make krmed's change, since that might just be fixing the symptoms and not the real issue. It is the memory allocation version of the "off by one" error where someone fixes the problem by just adding one without tracking down the reason why the value is off by one.
Another problem might be that your closedown code isn't being invoked. I often see people spend endless amounts of time trying to figure out why are routine isn't working when in fact, the routine isn't even being invoked.
Both of those problems are the same class of problem, improper execution path.
Of course, this is all assuming that it is CallSumBin that is leaking. If you haven't verified that, then you might be looking at the wrong issue.
As to what Christian said, he is right. Constructing the filename like that is akin to running with scissors. As long as you are careful, things are "ok". But a slight mistake can cause memory corruption (which can manifest itself as a leak in some instances) and security issues. I won't go so far as saying C style is crap, mainly because I have seen far too many string processing systems created with managed strings that are just dogs. But you are playing with fire and really need to understand what you are doing when you do work with C strings.
