I'm sure simply doing something like this would do:
<code>
UINT WorkerThread(LPVOID pParam)
{
while(TRUE)
{
Main* pMain = static_cast<Main*>(pParam);
if(pParam != NULL)
pMain->FunctionImTryingToCall();
}
return 0;
}
</code>

I have written a programe for playing movies.It works well
in debuging. But using the .exe file in Debug directory, it only can play a few time,why? How can I resolve it?

It displays "0x00213000 citing by 0x03862f76 is unable to read".But why no problems in debuging? Where is the difference between them? Thanks!

Perhaps an uninitialized pointer, or a pointer that is being used after it has been deleted. This article might be of interest.

I am using blowfish...
I have a database of records I wish to encrypt...what would offer best encryption not so much performance, but rather strength of encryption or does it make a difference?
Should I:
1) Encrypt an entire database file
2) Encrypt each record individually...that way the SQL engine can still return record data, but it would be all scrambled? I think I wanna go with this method, but i'm concerned about possibly weakening the strength becuz the message digests??? would be smaller...around 1024 bytes.
If you encrypt a large file say 2 MB with a single password, doesn't everything get smashed togather and provide better security in the theory that to decrypt a large file would naturally take longer then 1024 byte block of data? I'm no cryptologist so don't get to fancy with explanations...
I don't like the idea of encrypting a database file either, becuz of the possibility of unencrypted remains possibly being extracted...with a low level disk viewer or something...I would like to do everything in memory, that way there is no chance of data theft.
Any suggestions or ideas???
Thanks...again
Cheers

How MD is connected?

Not necessarily. Depends how blocks are chained. More important is compress before encrypt, or xor with random bits.

Not really realted to sockets specifically, but I plan on using them to request HTML pages, so it's kinda ties into the question.
When a browser has an adddress typed, say codeproject.com does the download engine or whatever you call it...get 2 seperate streams?
1) HTTP Response
2) HTML file or document whatever?
Or is this HTTP info concatenated to beginning of HTML file? What happens when you request an PDF file then?
Consider the following code snippet from Stephane Rodriguez
DWORD CHttpProxyMT::DataThread(void *parm)
{
socket_pair* spair = (socket_pair*) parm;
while( (spair->n=recv(spair->srcsock, spair->buff, 16384, 0))>0 )
{
spair->buff[spair->n] = 0;
if (g_bFilteringEnabled && spair->m_bIsServerResponse)
{
CHtmlFilterRules filter( spair->buff,spair->n );
filter.ApplyRules();
}
send(spair->dstsock, spair->buff, spair->n, 0);
}
...
}
Does the while loop iterate twice? Once for the HTTP request and the other for the HTML document itself?
Thanks

The HTTP headers and file are sent in the same stream separated by a blank line.

I have been programing in c for sometime and just recently am going to c++ for school. I have Microsoft Visual c++ as a compiler...My question is can i use regular C code or C++ code without problems or will i have to learn Visual c++ i do anything....Basically is what i am asking is it backward capatible with c and c++

Hello,
You can use Win32 Console based application project type for C or C++ program with out any problem.

Both are fine.
One thing to remember is that a .C file can only contain C code, while a .CPP file can contain both C and C++ code.

Hi All
I have a MFC client wich is a part of big 3-tier application. Recently, I've begun to convert some parts of it into managed code.
By that, I mean that I rewrote some components of the app using C# and imported them into my app as a COM components (including the communication with the server wich I changed from COM+ to .Net remoring).
It works fine, but when I close the application I get exception in call to corExitProcess().
Does anybody know something about that?
Do I have to shut the CLR in some way?
thanks!

Hi!
I have to do a CORBA interface for my Visual C++ application and I have no idea. What should I do? How could I start? Where could I find some information about this? Any advice will be welcome.
Could I ask questions about this here or is there any other board for this theme?
Thank you in advance!

It's not that different from creating a COM interface for you application (in fact, that's one path you can take: create a COM interface and use a COM/CORBA gateway app). You design an interface for the application (that is, the services it will provide to other applications) in IDL. You then run the IDL through the IDL compiler provided by your Object Request Broker (for a COM object you run the IDL through MIDL). The IDL compiler will generate code that has the C++ interfaces to the functions you described in IDL. You write the implementation of those functions, using the rest of your application. Then you link that together with your application and libraries provided by the ORB vendor.
Usually, if you are being asked to do this your employer will have an ORB in mind. You'll have to get details from the ORB documentation. I think there are at least one or two open source ORBs around, as well.

Suppose I have the same icon in 3 different formats: 4, 8 and 32 bits. How do I load them with a specific bit depth using the win32 API? I want to do something like this:
HICON hIcon4 = Load4BitIcon(IDI_ICON, ...);
HICON hIcon8 = Load8BitIcon(IDI_ICON, ...);
HICON hIcon32 = Load32BitIcon(IDI_ICON, ...);
LoadImage just doesn't (seemingly) cut it.

I've had a quick look, and can't find a LoadIconDepth function either. What you might have to do is
use FindResource, LoadResource, and LockResource to get at the raw data, extract
the data for the colour depth you are after, and then create afresh using CreateIconIndirect.
Unless anyone else has any ideas?
I am a little puzzled as to why you want to though. Windows automatically loads in the icon
appropriate for your specified size, and screen colour depth with LoadImage.
Iain.

I'm on it.. Found a nice article on icons at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwui/html/msdn_icons.asp[^]

Ah yes, but it seems that 32-bit icons are incompatible with various components such as image lists. When I use LoadImage() to prepare an image list, I often get "weird" artifacts in the icons when they are drawn in list boxes and the like. If I draw the icon myself with DrawIconEx() they turn out just fine, but not in common controls. 
That's why I'd like to be able to specifically ask for an 8-bit icon, which I know renders perfectly.
If you know why list controls behaves this way with icons and know how to make it stop, then please, enlighten me. (I'm using WTL, but I don't think that's the problem since it only thinly wraps the system control)

Is this problem reproducible on other systems with different graphics drivers?
I ask because I was having a problem with toolbar button icons (for example, in IE and WinZip) with a previous version of nVidia's drivers with this system's Riva TNT card. Reverting to the version on the XP CD fixed it. The latest drivers appear to have fixed the problem.
Unless you can reproduce it on a number of other graphics cards/drivers, I'd blame it on the graphics manufacturer.
You could also see if it goes away if you reduce the hardware acceleration level.

You may want to try ExtractIconEx, passing the actual resource ID to load. An excerpt from the docs:
nIconIndex
Specifies the zero-based index of the first icon to extract. For example, if this value is zero, the function extracts the first icon in the specified file.
If this value is –1 and phIconLarge and phiconSmall are both NULL, the function returns the total number of icons in the specified file. If the file is an executable file or DLL, the return value is the number of RT_GROUP_ICON resources. If the file is an .ICO file, the return value is 1.
V NOTE THIS SECTION V
Windows 95, Windows NT 4.0, and later: If this value is a negative number and either phIconLarge or phiconSmall is not NULL, the function begins by extracting the icon whose resource identifier is equal to the absolute value of nIconIndex. For example, use -3 to extract the icon whose resource identifier is 3.
Once the array of icons are loaded, you can simply pick index 0 for 8 bit, index 1 for 16 bit, index 2 for 24 bit, etc.
onwards and upwards...
|
|

|

As I read it, this won't help. The ExtractIconEx gets the icons from a file. A big and small icon for
each ICON. He can already load a particular dimension of icon from his own files using LoadImage.
What he needs to do is to pick a particular colour depth icon, when a ICON may have icons with the same
dimensions, but differing depth.
Unless I'm wrong. It's not *my* question to start with after all!
Iain.

I have created a 3D model and want to include a light source,
after I created it, the colour of the whole model changed to one colour...
moreover, the light source was not fixed in one position and changing all the time...
can anyone pls tell me how to fix this and provide me some examples??
thx very much~~
