CSocket uses the thread's message pump. A worker thread does not have a message pump.

hi
i wanted to know wheter i can use an Activex control without registering it??
for example use an Activex Control wich is in the same Folder??
i've built a program using an activexcontrol. but it needs to register the control first. but on a network i cant register it( i think modifing the registery is illegal)
thx

No, you have to register it. Run regsrv32.exe <your file>.dll on the remote machine.

Recursive FindFirstFile/FindNextFile? If you need it programatically, that is.
If you'd just like to know, you could go to the root of every partition using Explorer, select everything, and hit Properties. 
Oor! If you have cygwin installed, you could count the lines of a "find" started from the root. :P

I need it programatically. I tried FindFirstFile/FindNextFile but recursion is a bit too slow and uses up too much resources. I thought there was a data structure for each partition that had all the partition information including number of files and folders.

I have ClistCtrl (report view) with images. I want the images to be at the center of the column, not at left of the column.
How can I centralize the images?

You will need to use 'custom draw', a feature of the common controls including the list control. You can find information in the MSDN using "custom draw" as the search string. I would post a direct link for you, but the MSDN site seems to be acting up at the moment  .
Custom draw lets you perform some or all of the drawing required for the control. It's easier than the 'owner draw' feature the traditional controls implemented, where you have to draw the whole thing. With 'custom draw' you can have the control do the standard drawing, and then add your piece where appropriate.

Thank you!
I understand how can I change the font of text for example, by custom draw.
But while I process the message of drawing an image, how can I draw the image (icon) at the center of the column?
|
|
|
|
|
If you know the dimensions of the icon, you can center it based on the RECT passed to the custom draw handler. Use the ::DrawIcon function to draw the icon.

hi
i need to transfer a file from one system to another over LAN.
For that i use the code given at
http://www.thecodeproject.com/internet/SocketFileTransfer.asp.
At the receiving side while receiving it gives error WSAEWOULDBLOCK and number of bytes received -1. A blank file is created at the receiving side.
any clue please.

Although WSAAsyncSelect can be called with interest in multiple events, the application window will receive a single message for each network event.
As in the case of the select function, WSAAsyncSelect will frequently be used to determine when a data transfer operation ( send or recv) can be issued with the expectation of immediate success. Nevertheless, a robust application must be prepared for the possibility that it can receive a message and issue a Windows Sockets 2 call that returns WSAEWOULDBLOCK immediately. For example, the following sequence of events is possible:
1.Data arrives on socket s; Windows Sockets 2 posts WSAAsyncSelect message
2.Application processes some other message
3.While processing, application issues an ioctlsocket(s, FIONREAD...) and notices that there is data ready to be read
4.Application issues a recv(s,...) to read the data
5.Application loops to process next message, eventually reaching the WSAAsyncSelect message indicating that data is ready to read
6.Application issues recv(s,...), which fails with the error WSAEWOULDBLOCK.
Other sequences are also possible.
I Hope this Helps..........;)

It has been such a very long time since I've coded the Win23API and now my memory escapes me. I want to iterate open windows (enumwindow) get their hWnd and then present them in a form with a checkbox next to each window. When the user puts a check in the box it will "Remove From Taskbar" when the remove the check it will "Show In Taskbar". I know how to do this inside the application but I cannot seem to find any documentation for how to do it to an application you don't own. It's been since 1999 that I did this stuff and I just don't remember now...
Clues???
I only read CP for the articles.

There are a couple of window styles you can twiddle - WS_EX_APPWINDOW and WS_EX_TOOLWINDOW. There's also a COM interface for manipulating the taskbar: ITaskbarList.

hello,
is there a non-registy way to change the default location of the special folders, like Favorites or Temporary Internet Files? Something that will complement the SHGetFolderPath function?

I know the difference between std::string and std::wstring etc, but I was wondering if there was a standard header file like tchar.h for defining a code neutral way of coding that would automatically select the proper string type to use depending on the UNICODE preprocessor define. I can easily roll my own, but is there a standard one?

I haven't found any! I have created an incomplete header that contained code like this:
typedef basic_string<TCHAR> tstring;

If so just send it to the email address you find in the emailed reply notification you get with this message.
Thanks

I will need to look for it. I have not used it for some time since I only program on 32-bit platforms and only use Unicode. I think it might be at work.
|
|
|
|
|
Also, I just remembered a couple of problems I ran into using the header file.
The filename argument for file streams are always narrow, and support for multi-byte character strings is limited. However, I wrote the header file for vc++ version 6. I haven't used it with the new versions since I have been using MC++ or C++/CLI almost exclusively.

How about:
extern tistream& tcin;
#endif
#ifdef _UNICODE
tistream& tcin = wcin;
#else
tistream& tcin = cin;
#endif That should be preferable to defines, as it will preserve the variable and typename, which may be helpful when debugging.
If you're not compiler sensitive (portability etc), you can always try
#ifdef _UNICODE
__declspec(selectany) tistream& tcin = wcin;
#else
__declspec(selectany) tistream& tcin = cin;
#endif __declspec(selectany) eliminates the need for a .cpp file, as it instructs the compiler to allocate space for the reference in one and only one compilation unit. Nice if you want to eliminate the need for lib files.
