Can you explain - hopefully with an example. A Simple example will suffice.
Thanks!

Sorry for late reply. actually i want to say.. do you lenghty work in thread.. so that it will not block the main thread and you can easily do you work over there

Hi,
First of all I hope this is the right place for this question, if not please direct me to the appropriate place and accept my apology in advance.
I'm a beginner level programmer and have done some C and C++ in school. My work is more of a sys-admin nature so I unfortunately don't get a chance to polish my coding skills through work either.
I need to write a small windows utility to act as a dhcp server for 4-6 windows clients. This is a private type project and for some reason the requestor does not want to use any existing freeware/shareware or even the windows built-in dhcp server. The scenario is a setup of 4-6 windows machines, one of which would be running this utility to act as a dhcp server. As far as I understand, all machines are running win xp.
As I mentioned above, I'm just a beginner level so this may be out of my scope and I understand that but that is EXACTLY the reason why I want to do this. I have a few weeks so I'm hoping that should be enough time to learn and understand. I think this may be a very good opportunity for me to better my coding skills since its a real project and not book exercises. I have read up on dhcp in the last couple of days and now atleast understand what it is and what it does.
Can someone please guide me on this, so I can atleast have an idea of what I need to learn/understand and where to start. Also, since its code, I'm assuming it could be done a variety of different ways, so if there are multiple suggestions, all are welcome...
Thanks very much...
uzee

One of the things that I have been working on for the past couple of days is creating a DLL in VC++ 6.0 and using it in VC#, and it works..... but when I create the dll in VC++ Visual Studio 2005, it doesnt work with the VC# code.(in Visual Studio 2005)...... I get the error message that it could not find the fntest () function in TestDll.dll.
Let me be more specific about how I created the DLL.....( and I followed the same steps for VC++ 6.0 and VC++ 2005).
After following the steps in the link http://www.icynorth.com/development/createdlltutorial.html(I created a project that exports some symbols instead of a simple dll)I created a .def file, specified the test function as EXPORT. Then I went to build->configuration manager. and changed the configuration from debug to release. I then built the project, got the dll and copied it to the folder C:\WINDOWS\system32.
Then I used PInvoke in VC# code and it worked fine for a VC++ 6.0 dll but not for a Visual Studio 2005 dll in VC++. I have a code ( written by someone else) in Visual Studio 2005. It has a lot of libs etc. specific to .NET, so I have to convert this code to a dll and then use it in my VC# program.
I am desperately waiting for a response.
Thanks,

If you update your VC6 project to 2005, does it still work ?

If it's specific to .NET then it's managed code, which means you should be building a managed dll ( in fact, you have to ) and you won't p/invoke that, you'll just import it.

Hi all,
I want to enumerate files in a folder that has a large amount of files, I use FindFirstFile and FindNextFile but they seem to be slow, furthermore, they extract file attibutes for all files/folders they enumerate...
Anybody has an idea on how to boost performance? or are there othe file enumeration functions I should use??
Plz help 
Mohammad

FindFirstFileEx allows you to use these options:
typedef enum _FINDEX_SEARCH_OPS
{
FindExSearchNameMatch,
FindExSearchLimitToDirectories,
FindExSearchLimitToDevices
} FINDEX_SEARCH_OPS;MSDN docs also state that these options are advisory only, meaning that the function could ignore it. Your mileage may vary. 
Requirements
Client: Requires Windows XP, Windows 2000 Professional, or Windows NT Workstation 4.0.
Server: Requires Windows Server 2003, Windows 2000 Server, or Windows NT Server 4.0.
Header: Declared in Winbase.h; include Windows.h.

while ((ch = getchar()) !=EOF && isdigit(ch)){<br />
result = result *10 + ch - '0';<br />
}<br />
printf("number is %d\n", result);<br />
i wonder what is '0' means. Is it is null character?

actually it's not null.. actually it is ascii based calculation.. i.e. '0' ascii value is 41 , '1' will 42 and so on.. so it way of extracting number from char character ... thats logic here

Hi All.
I start to learn multiThread and i wrote some simple program.
I dont know why i crash - i try to look into by using debug and i dont see nothing wrong.
IF someone can tell me what i doing in wrong way .... ?
Thanks for any help.
Here the code :
<br />
...<br />
...<br />
<br />
using namespace std;<br />
<br />
CRITICAL_SECTION sc;<br />
<br />
void __stdcall func(LPVOID param)<br />
{<br />
char szBuffer[256];<br />
{<br />
EnterCriticalSection(&sc);<br />
long lVal = *((long*)param);<br />
<br />
<br />
while(lVal > 0)<br />
{<br />
sprintf(szBuffer, "lVal is : %ld \n", lVal--);<br />
printf(szBuffer);<br />
}<br />
LeaveCriticalSection(&sc);<br />
}<br />
}<br />
<br />
<br />
void main(void)<br />
{<br />
HANDLE thread1,thread2;<br />
<br />
long lVal = 10;<br />
<br />
thread1 = CreateThread(NULL,<br />
5,<br />
(LPTHREAD_START_ROUTINE)func,<br />
&lVal,<br />
CREATE_SUSPENDED,<br />
NULL);<br />
<br />
SetThreadPriority(thread1, THREAD_PRIORITY_HIGHEST);<br />
<br />
lVal = 1000;<br />
<br />
thread2 = CreateThread(NULL,<br />
5,<br />
(LPTHREAD_START_ROUTINE)func,<br />
&lVal,<br />
CREATE_SUSPENDED,<br />
NULL);<br />
<br />
SetThreadPriority(thread2, THREAD_PRIORITY_HIGHEST);<br />
<br />
ResumeThread(thread2);<br />
ResumeThread(thread1);<br />
<br />
WaitForSingleObject(thread2, INFINITE);<br />
WaitForSingleObject(thread1, INFINITE);<br />
}<br />
