Thank you for replying. I was afraid someone was going to tell me this. I don't understand why they do this other than as an optimization. It doesn't save that much time and they are just using more memory.

Does anyone have a list of CP web services - you know, the CP URLs ending in ".xml"? I could've sworn I saw at least one reference (the last "n" posted articles service), but it was 4am and I was fading. I didn't save the link and am now kicking myself. 
Thanks,

By the way did you see my screen saver using your WebResourceProvider thru C#. Thanks for WRP.

Yes! You did a great job of wrapping it for C# use! As soon as Tom's book shows up at my doorstep, I'll start learning C#. I feel so... oh, what's the word I'm looking for... "STUPID"! that's it!

I'm still pretty new to GDI programming, but it was my understanding that as long as I select the original GDI object back into the DC, the resource would be cleaned up properly when it goes out of scope ( I am not using pointers for these objects ). What I don't understand is why the GDI resouce count ( in the Task manager under Windows 2000 ) shows the GDI resouces growing to an unmanageable amount in a very short period of time ( e.g. 2,000 in under a minute of program execution ).
Here's what I've done. I have a multi-threaded application that draws bar graphs to the screen (among other things, but we'll just focus on the bar graphs). One thread reads data from the serial port and writes it to a global data structure. A draw thread then gets notified that it has updating to do and it reads data from that data structure. That draw thread then calls Draw() on a global bar graph container object.
I have created a bar graph library that abstracts the bar graph functionality. The container class I mentioned above (CObject inherited), holds four bar graphs and is responsible to update internal data of each of the graphs. One of these container objects is used throughout the program and is global. I call Draw() on this container class (passing it a DC) both in the view's OnDraw and also in a secondary draw thread (as mentioned above) (CWinThread inherited). I synchronize access with a critical section. I think that the problem is in this global class.
Is there something about global classes that I am not taking into account here when it comes to GDI? My GDI objects that I create are created in the scope of the function (method) and not in the the class scope (e.g. m_gdiObjectName ).
Any suggestions would be helpful ( I hope I've been clear enough ).
Thanks.

For all of the GDI objects that you create, are you calling DeleteObject on them, and DeleteDC or ReleaseDC for the device contexts that you create.
Because part of allowing the GDI objects to properly destroy is to replace the original objects into the DC, because this frees the objects that you created to be properly destroyed.
You should always destroy the objects that you explicitly create.

According to the GDI source code, the destructor of each of the GDI objects should be doing this for me. The destructor calls this:
BOOL CGdiObject::DeleteObject()
{
if (m_hObject == NULL)
return FALSE;
return ::DeleteObject(Detach());
}
My objects are all created without using new and should be destroyed when they go out of scope. It doesn't appear that they are.

Sorry, I forgot that you were using GDI wrapper objects. So if you set a break point in the destructor for your objects, are the objects being deleted properly?

Yep. They're getting deleted. I'm stumped here.

I want to use CSockets to send a file(text file) across a network. One program is the server, and the other is client(of course). What is the easiest way to do this?
|
|
|
|
|
Microsoft has a really good example of this. Go to http://support.microsoft.com/default.aspx?scid=kb;EN-US;q175668. This example will work running both client an server on the same machine, but you could very well move the server to another machine on your network and see it work over a network.
Best Regards and good luck.

Look up TransmitFile declared in Mswsock.h
MSDN ___
The Windows Sockets TransmitFile function transmits file data over a connected socket handle. This function uses the operating system's cache manager to retrieve the file data, and provides high-performance file data transfer over sockets

If he use TransmitFile... how does the other side receive the file then!?

Unfortunately there is no ReceiveFile
So we'll have to recv() the entire data .

I may have to kill you. That totally freaked me out. I was thinking "Oh Crap! Where is that backup CD?".
Good laugh, though. How did you do it?

Hi
I have created a new dialog project. Now I want to add that PROJECT into an exitsting project's workspace. I can do this but the dialog project outputs a .exe file. How do I change this to create a .lib file so I can link correctly??
---

It doesn't really work that way. You'll need to create a "Win32 Static Library" ( File | New... in Visual Studio ). Once you've done so, you'll have a library project to work with. When compiled it will build a .lib file. This project is where you'll have to create your dialog and related class. It is possible to move your existing .cpp and .h file for your dialog into a static library such as this, but doing so is a bit of a pain. You will probably have to copy resouce code (from the .rc file) to a .rc file in the static library project. Making all the connections then is a bit tedious. Once you do have this library built, you will have to change the project settings in the main project so that it knows where to find your new library. I hope this helps steer you in the right direction.
Good luck.

Hi.
I have a char * to a data buffer. What is the best way to assign data from char * into a CString object? For example:
-----
// char *myChar = new char[10];
// memcpy(myChar, "abcdefghij", 10);
// CString myString;
-----
What is the best say to insert data from myChar into myString?
Thanks,
Kuphryn
