I see - I thought you were saying the opposite, that you needed something easier to understand. Yes, the SGI site is an excellent place to take it further.

Is this possible? I've had such dismal success in the past and I would really like to do so with the following code:

I apologize if this is inappropriate for this forum but I don't know where else to ask...
I'm working on an application which makes use of data stored in LZH archive files. I tried using Micco's UNLHA32.DLL but it pops out a Kernel32 access violation every time it extracts a file. LHA.DLL will only extract files to disk; I need to extract them to memory.
I can code my own handler for LZH header data but extracting the compressed data is beyond my abilities. Does anyone know of a good LZH library for C++ (to be used in VC++6) which can be used to extract files to memory?

Try Googling for LZH (or LHA). The source is freely available for (the original) LHA.

Hi.
I am working on a network client and one of its features is download files over HTTP server, i.e. www.abc-xyz.com/files.exe. The program downloads some files successfully, but it fails to download some files. For some reason, it download the all files, but some files are unvalid in terms of CRC.
I understand that the server initially sends information about a file including its size and type (Content-Type). However, for some reason files that have bad CRC seem to miss the beginning chunk of data. In other words, the program does the file, but the first twenty bytes might contain bad CRC. Here is the algorithm of the design.
- Send request (GET)
- Call WSARecv
- On first incoming data, analyze data and determine file size.
- Analyze data and save any valid data that server might have including with file information.
- Call WSARecv
- Continue calling WSARecv and appending new data until size of data equals the size that the server sent.
I would like to know is it possible that the server sends out the data before it sends out information about the data such as size? With the algorithm above, the program can download some file, but fails other files in terms of CRC. I cannot understand how that is possible because the size of the file is correct most of the time, but even so the files have bad CRC. Another interesting fact is that the bad CRC always occurs at the beginning such as the first 20 bytes.
Thanks,
Kuphryn

Have you taken a look at this http://www.codeproject.com/internet/winsockintro02.asp
Seems like this is what you're doing..
|
|
|
|
|
Okay. Thanks.
Conceptually, yes, Nishant S discussed a Winsock program I am working on. However, in reality my algorithm and his algorithm are completely different.
I understand his algorithm.

dear all,
1)i want to distribute my mfc app to a machine which does not have visual studio environment. my app is in form of an exe.
2)how do i link mfc to my app, statically or as a shared dll
can anyone shed light on it,
|

If you link statically then you do not need MFC42.dll, otherwise you do. Either way, you may need MSVCRT, it depends on if you use C runtime functions or not.

If you link MFC staticaly, the MFC code is linked with your app, so you don't need to redistribute MFC42.dll.
Dynamic linking saves RAM on the target system, if more apps using MFC (dynamicly linked) are running simultaneously, or if your application uses DLLs created with MFC.

dear experts,
I set up a global mouse hook for listening to mouse messages, mouseHook=SetWindowsHookEx(WH_MOUSE, MouseProc,hInstance,0);
in my MouseProc after I did my thing i called CallNextHookEx(mouseHook,nCode,wParam,lparam); however when I ran my program, if I move my mouse cursor outside of my app window, the whole desktop would disappear(possibly getting repainted) every few seconds, what's causing this weird behavior? how do I go about fixing it?
any help is appreciated

Hmmm... This forum is generally about VC, not VB. But if you want.. it's a SetForegroundWindow. This function "puts the thread that created the specified window into the foreground and activates the window. Keyboard input is directed to the window, and various visual cues are changed for the user.". You also can try to use SetFocus function, but i do not guarantee it will work between processes

1. I have an application (SDI) which works with database
that is, retrieves data and the data are displayed in Edit Boxes and Statics
I want to send these data to another program, MS Word in my case
how to do this ?
2. Is it possible with ADO?
thank you.
|
|
|
|
|
try with ShellExecute function.
In ADO i'm not sure.

You can send data to MS Word using Automation. See this[^].

Hi. I am using GetMenuItemInfo to retrieve information about menu items. I am using MENUITEMINFO.fMask = MIIM_DATA | MIIM_SUBMENU; and it retrieves the DATA (application-defined custom data) just fine for submenus, but not for top-level dropdown menus! But when Windows sends me WM_DRAWITEM, it fills in that DATA just fine for these top-level items! Any workaround for this?

I need help with one thing.
I don't really know how to communicate between my server and client. Am I going to use a plain string and parse it? Am I going to use a struct which is much easier because you don't need to do any painful parsing.
I want to use a struct that I send between the client and the server. But is it good or bad?
Is it something I need to think about?

It totally depends on the problem you're trying to solve. If you're doing a web server and a web browser, then yes, a string over tcp would be ideal. Or are you copying file data? Is it really small atomic items - 4 bytes? The maybe a windows message. Or COM might be your best option.
Are these items going to be on the same system, or a true client/server?

Well, I'm developing my own chatt server in order to learn socket programming "full out".
But I don't know how to create a good communication protocol and if it's going to be plain text or binary communication.
The first version of my chat will only have functionality for sending plain messages. Then when I know how to make that thing run good I will implement functionality for sending files also.

I prefer plaintext TCP/IP communication vs binary communication, when possible.
A good example of a mixture is the Gnutella protocol: Handshake and file transfar is done in a HTTP alike plaintext protocol. while all other stuff (search requests and answers) are binary... possibly to save bandwith. Generally speaking, text protocols are flexible, easy to debug and good to understand. Binary protocols are better suited when performance matters (you know optimation is your worst enemy).
IRC is an example for a line based plaintext protocol, ICQ is an example for using binary packages. Oh, and another possibility that is available: using XML (and a library that parse data for you).
If you speak about a chat, perhaps imitate IRC protocol and use line based plaintext...
