Hiya!!
im using borland 5.01 and i am trying to interconnect 2 computers with eachother over the internet .
i have to do it with windows (not linux), and it must be DOS (standard).
I have only 2 obstacles in my way so far...
1-does anyone know what functions exist for me to connect to a pc, knowing its IP address?
2-does anyone know what functions exist for me to obtain a pc's IP address, knowing its name?
to use these functions, what libraries must be included and where can i get them?
Thanks

You can use sockets.
You can find sample codes at http://www.geocities.com/jcynion/jcynion_codes.htm, Echo Server sample
Though the server project is a VC++ you can just extract needed classes to create Win32 console mode application.

I am trying to create a very simple file/folder browser using the shell, similar to the right hand pane of windows explorer. It should list folders (along with special folders), which can be double-clicked to drill down to the next level. To return to the parent directory, the user can double-click the ".." folder.
However, I have run into a problem. The only way to get the parent folder, is to call SHBindToParent (which doesn't exist on some platforms, but that's a discussion for another day  ). SHBindToParent requires a full PIDL in order to work.
On the other hand, IEnumIDList (used for listing the contents of a folder) returns relative PIDLs. Once I have enumerated a folder and displayed its contents, I can see no sensible method of returning to the parent. I could "remember" the parent before opening a sub-folder, but I may not always start at the desktop, so I will be missing some information on my way back up the tree.
I need a full PIDL to call SHBindToParent, but I only have relative PIDLs returned from IEnumIDList, and there's no way (that I can see) to build a full PIDL from a relative one. (IShellFolder::ParseDisplayName and IShellFolder::GetDisplayNameOf don't do what I want, and since I only have relative PIDL's to work with, the results are not always useful anyway).
I was wondering how Microsoft managed to create Explorer without any mechanism for obtaining the parent and then I realized that they are using the tree control to do it! Does this mean I have to scan the entire file system and store it as a tree in my application?? Surely there must be a more intuitive way to get the parent of an item in the file system?
Any help would be greatly appreciated. 
Thanks.

I am trying to call OpenGL functions in a managed C++ dll, but the OpenGL functions are not expecting pointers so I am getting errors from managed C++ saying: 'glutDisplayFunc' : cannot convert parameter 1 from 'void (void)' to 'void (__cdecl *)(void)'. Help?!
|

|
|
|
From what I remember, OpenGL callback functions have to be unmanaged, not managed functions.

Reading Ryan Binns post, I'm not sure if I'm misguiding you as I have absolutely no knowledge about Managed C++. But there is a chance that you have set VC up to declare functions as WINAPI/FAR PASCAL, so your functions signature is not 'void (__cdecl *)(void)' but 'void (WINAPI *) (void)'.
The difference is quite significant, as it affects the way parameters are pushed on the stack.
Try changing the signature of your function to eg. void __cdecl DoSomething(void);

I have picked a project that involves Database progamming and I have never worked with databases before. I was wondering if anyone has any website reasourses that I can goto to start learning how to write database programs.
|

|

First thing you need is a database. I recommend downloading MSDE or Sql Server 2005 Express Beta from Microsoft. Then read the MSDN, and articles on this site, on how to interact with it.

Do a google search for sql. You will get plenty of answers. Might have to narrow it down a little, but that is good practice.
There is a reason I didn't give you a site: you need to learn to use google instead of asking, it is faster and easier in the long run.
I don't know that I'd recomend MSSQL as strongly as the other guy, but it works. mySQL is popular, postgreSQL is free and good. Oracle is the most popular. There is also DB2. And you can write your own if there is something specific you need to do.
Stay away from toys like Microsoft Access. Access works, but it isn't very good in subtile ways that you may or may not discover for years. (MySQL is a toy too)

Hello,
I'm getting an internal compiler error C1001. Microsoft says it's a bug. More information on the bug can be found here[^].
I triple checked my compiler options for the /Zg option, and it's simply not specified, but I do get the error C1001.
This error comes up when I want to initialize a private static array of structs.
<br />
class a : public CMessageBase<br />
{<br />
private: <br />
static const MYSTRUCT *myStruct[]; <br />
};<br />
const MYSTRUCT *a::myStruct[] = {{0, 0, 0, 0}};<br />
Does anybody have an idea?
Thanks in advance
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

The internal compiler error (affectionally called ICE) means just that the compiler crashed for whatever reason. It is a bug in the compiler, simply put. There are tons of situations leading to an ICE, at least in MSVC 6.0. Some of these situations involve valid C++ code (that usually is too complex for MSVC), and some other situations involve illegal C++ code. Even in the latter case, the problem remains primarily with the compiler, as crashing is not a reasonable response to a program, incorrect as this might be. At least, you still have the chance to try to determine by yourself what the problem in your code is and try to get the compiler back to sanity.
In this particular case, I think your code is wrong. The line
static const MYSTRUCT *myStruct[]; declares an array of pointers to MYSTRUCTs, while
{{0, 0, 0, 0}}looks more like an array of MYSTRUCTs. Could this be your problem?
Also, the MSKB article you refer to is just a situation leading to an ICE, but I don't think it has anything to do with your particular problem.

Hello,
Thanks for your reply. The problem was indeed with my code using a 2D array of pointers. After I rewritten the code using 2 seperate arrays (one of pointers, one of MyStructs), it works perfect.
Anyway, here is the solution of the problem:
<br />
class a : public CMessageBase<br />
{<br />
private: <br />
static const MYSTRUCT* MyStructs[2];<br />
static const MYSTRUCT MyStruct[]; <br />
};<br />
const MYSTRUCT* a::MyStructs[] = {NULL, &a::MyStruct[0]};<br />
const MYSTRUCT a::MyStruct[] = {{},{}};<br />
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

you are declaring an array of pointres to mystruct. you cannot initialize them to zeros(to NULL yes ) but not zeros. or so am lead to believe.

Have 0 (zero) and NULL suddenly become different?

Not necessarily. C1001's can be caused by lots of things. Most likely, the compiler is getting confused by other errors that it hasn't had a chance to print out yet.
Is there any reason why you're not giving the array a size? Try giving it one and see if that works.
Also, I'm not sure you can initialise a pointer to a structure with the {} method. Is your intention above to initialise the array to 4 pointers pointing to NULL? If so, you've got too many {'s - just use { 0, 0, 0, 0 }.

Hello,
I think that the thing I was trying to do is impossible the way I wanted to, leading to incorrect syntax. After rewriting the thing, solution posted above, it works like a charm.
Thanks for your help.

Hi!
I have created a dialog-based application, and I want to create accelerators. For example, when the user presses F2 key, I want to show the aboutbox dialog.
In the OnInitDialog function, I added the following lines:
<br />
HACCEL m_hAccel=::LoadAccelerators(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_ACCELERATOR));<br />
ASSERT(m_hAccel);<br />
m_hAccel is defined as HACCEL.
Also, I added the following member function:
<br />
BOOL CCRDlg::PreTranslateMessage(MSG* pMsg)<br />
{<br />
if (m_hAccel != NULL && TranslateAccelerator(m_hWnd, m_hAccel, pMsg))<br />
return TRUE;<br />
<br />
return CDialog::PreTranslateMessage(pMsg);<br />
}
My Resource definition is defined like this:
<br />
<br />
IDR_ACCELERATOR ACCELERATORS <br />
BEGIN<br />
VK_F2, ID_ABOUT, VIRTKEY, NOINVERT<br />
END
But this code doesn't work, my accelerators don't generate a WM_COMMAND.....
What's the problem?
Thks in advance!

You cannot expect other member functions to have access to this local variable. The variable must belong to the class.

Hi!
I'm looking for a way to draw transparent Slider controls, instead of drawing it with a grey background.
Is there a message to handle like other control (WM_CTLSTATIC,...)?

Will you explain little bit more. I mean what you want to do, once user click on right or left click.

Can anybody let me know if there is a way to change the caption name on a button (if you were using another language), without changing the dialog.
In other words can you read the caption names from a file?
Many thanx
