Forgive me if this is a stupid question. I'm a bit of a novice.
I'd like to determine when a network provider is finished installing/initializing and ready to use. My app runs while the provider is being installed. I'm trying to loop as follows:
while(strcmp(netprovider_buf, "NetWare Services") != 0)
{
WNetGetProviderName(
WNNC_NET_NETWARE,
netprovider_buf,
&buffsize
);
}
My idea is when netprovider_buf equals "NetWare Services", I know I can execute the login and successfully login. The problem I'm experiencing is after the first call to WnetGetProviderName in the loop, if NetWare Services hasn't finish initializing, subsequent calls to WnetGetProviderName do not fill netprovider_buf even after NetWare Services does finish initializing. (Sound confusing yet?)
If I don't run my app until after I know NetWare Services is running, then it works fine.
It seems that the MPR somehow blocks the function from working if it fails to return the provider name after the first call. If I close my app after it fails and then re-run it, it does work.
This is all to help improve SLP resolution using NwDskPe http://www.veder.com/nwdskpe/
Thanks for any help

This seems like an awfully "tight" loop, meaning that it is not yielding control of the CPU very often.
That aside, would the following help:
while (strcmp(netprovider_buf, "NetWare Services") != 0)
{
buffsize = size of netprovider_buf here
WNetGetProviderName(WNNC_NET_NETWARE, netprovider_buf, &buffsize);
}

u know
id put a timeout in that loop too just in case
and maybe a sleep(200) to yield the cpu

Sorry folks,
The code I posted was meant for illustration purposes. In reality I'm only calling the function every few seconds.
My actual code looks something like:
SetTimer(hWnd, timerID, 3000, NULL);
SetTimer is called in my InitInstance function and I'm handling the WM_TIMER message with:
case WM_TIMER:
if(strcmp(netprovider_buf, "NetWare Services") != 0)
{
buffsize = sizeof(netprovider_buf);
WNetGetProviderName(WNNC_NET_NETWARE, netprovider_buf, &buffsize);
}
else
{
strcpy(status, netprovider_buf);
InvalidateRect(hWnd, NULL, TRUE);
UpdateWindow(hWnd);
KillTimer(hWnd, timerID);
}
break;
I'm sure most of you have an even better way, but none of it works anyhow. 
Even when I created a messagebox that would only execute the function when I pressed "OK", still nada. I think this may be a limitation in the Wnet api that I can't overcome, but hopefully I'm just overlooking something.
Thanks for the replies.

hello everyone.
I have trouble with creating a custom entry point. It's definition is int ExeMain() and it is part of a static library which is linked with the executable.
But when I set the entry point to ExeMain, the linker complains about an unresolved symbol to _ExeMain.
When the ExeMain function is defined directly in a cpp file of the executable it works, but not like that.
Any ideas?

The entry point has to have the __stdcall calling convention and no name decoration. If you just write it as int ExeMain(), it gets name-mangled by the compiler as all C++ functions do.

I have a listview in large icon mode. I need to control the image displayed when item is selected. That is, instead of the default fogging the list view provides, I want to display special "selected" image (known at creation time). Is it possible?
Also, is owner draw mode supported for not report mode?

I want to know if there is a way to figure out
a perticular dialog is enabe/disable. I use enable
/disable this dialog by the function "EnableWindow(FALSE/TRUE)"
,but before calling EnableWindow, I want to know if this dialog
is disable or enable to hide a bug.
Thanks in advance.

IsWindowEnabled() should do the trick!

Any particular problems you want to discuss ?
have you tried coding some part of it ?
do you understand the problem at hand ?

Homework, eh? If you were to ask specific questions, rather than "Will you do my assignment for me?", you're bound to receive tons more help.

ah ah ah that is really funny anyway i just wanted the main algorithm thx

humm, I dont think you will ever get the solution to this problem unless you try solving it.

Listen funny man you are taking the forum the wrong way.. PPl will not write the whole code for you. Thats ur job. If you get stuck implimenting a logic sowewhere down the line then some one may help you, its not garanteed that you will get help. But a question like this, there is little chance for you to get help, Instead ask your friend who has got the similar assignment and has done solving it.

I am using strtol to catch bad entries:
looping on i
{
fgets(line, MAX_SIZE -1, fp);
pc = line;
for ( unsigned int j = 0; j < cols ; ++j, ++col)
{
num = strtol( pc, &pc, 10);
cout << i << " " << j << " " <<num<< " pc " << (*pc==' '?'.':*pc) << endl;
line comes from a file that looks like:
9 a5 3 9 1 3 9 5 5 7
10 9 4 6 10 10 8 5 1 7
10 12 1 3 10 10 10 11 12 3
/// an 'a' snuck in...strtol should arrest it, but it never does.
(however with a9 5 3 9 3 9 3 8 5 3, I see the letter 'a' in the cout.....)
Here is the output for the first case (when a doesnt show...)
0 0 9 pc .
0 1 0 pc .//pc should have been 'a', num is 0 is okay since it didnt get read
0 2 0 pc .//'num' should have been 5
0 3 0 pc .
0 4 0 pc .
0 5 0 pc .
0 6 0 pc .
0 7 0 pc .
0 8 0 pc .
0 9 0 pc .
Any ideas why strtol isnt performing as I understand it should?
thanks,

What are you expecting it to do? When calling strtol("9 a5 3 9 1 3 9 5 5 7", ...), processing stops at the space following the first 9 because that is the first character that it did not recognize as part of the number. The same is true for calling strtol("a9 5 3 9 3 9 3 8 5 3", ...), in that processing stops at the 'a' because that is the first character that it did not recognize as part of the number. Had you used base 16 instead, processing would have stopped at the space following 'a9'. Make sense?

right, the first arrest is at ' ', but right afterit should choke on 'a' as well......
23 12 a4 56.....
It never prints out *pc = 'a'
