While this is a true statement, you can't assume that Giorgi knew that an answer had already been posted. A common method for me when replying to posts is to right-click on each of the posts that I want to reply to and select Open in New Window. At this point I go through each one, re-read it, type my response, and submit it. It may be 30-45 minutes before I get to the last one and several others might have replied in the meantime.

If you had written it as an NT Service, you could mark it startup type as AUTOMATIC. Then it could run without a user being logged in without much trouble.
If you already have an EXE that has a user interface, then it is better to use the RUN method, as suggested. Another option is to add a shortcut to the Start Menu | Programs | Startup item to cause your progrma to run when the user logs in. This is more 'apparent' to the user than some 'hidden ' registry value.

Hi, my application will not have a user interface, so i dont understan what is the "mark it starup type as automatic" and where i mark it.
And another cuestion is if for example i have 2 different users and in one user have running the application but i dont want that the other can't stop this application, it is possible, doing it like u say in the sartup?

If you have a Windows NT service, and its configuration is to run 'Automatic' it will start when Windows starts and will be running already for each user.

If you don't want a particular user to be able to stop a service, make sure he is not an administrator on the local machine, or else deny them the start/stop service security privilege.

Actually the first argument to InternetGetConnectedState() is a mask that can be used to check any of the following situations:

Local system has a valid connection to the Internet, but it might or might not be currently connected.
Local system uses a local area network to connect to the Internet.
Local system uses a modem to connect to the Internet.
Local system is in offline mode.
Local system uses a proxy server to connect to the Internet.
Local system has RAS installed.

I am having trouble with this code. This is giving output as mesgbox with 0, ie successful, but is not filling the image. Please look in to it. I want to replace all connected pixels of a particular color with another color. Normal function outruns stack memory.

Any suggestions will be appreciated.

void dlg::OnButton1()
{
CClientDC* hdc= new CClientDC(this);
CFileDialog fd(1,0,0,0,"Bit Map(*.bmp)|*.bmp||");
fd.m_ofn.lpstrTitle="Browse";
if(fd.DoModal()==IDOK)
{
str=fd.GetPathName();
HBITMAP hBmp = (HBITMAP)::LoadImage(NULL,str,
IMAGE_BITMAP,0,0, LR_LOADFROMFILE|LR_CREATEDIBSECTION);

bmp.Attach(hBmp); //bmp is member of the class dlg

CClientDC dc(this);
bmDC.CreateCompatibleDC(&dc);
pOldbmp = bmDC.SelectObject(&bmp);

BITMAP bi;
bmp.GetBitmap(&bi);

dc.BitBlt(0,0,bi.bmWidth,bi.bmHeight,&bmDC,0,0,SRCCOPY);

bmDC.SelectObject(pOldbmp);

}
}

void dlg::OnLButtonDown(UINT nFlags, CPoint point)
{

COLORREF rgb;
CClientDC dc(this);
CQuickFill qf;
int i;

rgb=RGB(255,10,10);

i=qf.QuickFill(&bmp,point.x,point.y,rgb,CLR_INVALID);

if(i==0)
MessageBox("0","0");
if(i==-1)
MessageBox("1","1");
if(i==-2)
MessageBox("2","2");
if(i==-3)
MessageBox("3","3");

How to make multithreading application fast ?

5-Apr-05 19:40

Hi
I have developed a windows based service in C++ which runs on Windows 2000 Professional OS.

It is a multithreading service in which first it creates one master thread then it creates number of child thread in suspended mode. Now this child thread when resumed...gets the details needed....

For this I use Semaphore to synchronize the threads and WaiForSingleObject() functions to make it work properly.

It is like ....
---------------
if ( WaitForSingleObject(threadHandle,INFINITE) == WAIT_OBJECT_0 )
{
Do some work here.....
}
---------------
But some time it stucks waiting more time to finish so that new thread can start and continue working. So is there any other idea how can I make it run fast ?

Thankx in advance.

Depending upon what task your 'worker' threads are performing, you can always consider LOWERING their thread priority so that your 'controller' thread has a higher priority and the controller thread will get serviced more frequently when there is a task for it to perform, such as starting more worker threads.

You also might consider creating less worker threads and using a round-robin subdivision of the tasks to be performed, assuming your implementation can afford such a redesign. If each of these threads does not necessarily have to block on something, like a file handle or other event, then perhaps all the servicing can be done from a single thread that processes data for each item in turn, each time the thread executes. If you are making too many threads, your process will spend a significant per-unit amount of time switching threads constantly instead of getting 'real' work done.

MFC Active-X control project

Hi,
Instead of creating a new MFC Active-X project, i reused an existing project. But, when both the controls are being used simultaneously, i have the issue of same class-id for both the controls. How do i change the class-id of the control?

The active-x is being rendered on a web-page. Two different controls are needed and because of the same class-id i'm not able to use them.

Please help.

Thanks and Regards
Vikram Attiganal

Go through all your source files and change the GUID. I haven't done AX controls in MFC in ages, so I don't know off-hand which files to look at, but at the miniumum it will be the IDL or ODL file, and the code used for registration/unregistration of the server.

hi..
how do we save user entered text in a file.. i am using common dialog box and allowing the user to specify the file name and the location.. I used CArchive.. The first character in the saved file is always a garbage value.. Why?
regards

If you use CArchive, maybe that's normal... In fact, I never used CArchive for saving data but maybe it adds its own data before your data.
Try to use CFile instead:

char* szText = "Your string To Save";<br />
CFile* pFile = fopen("YourFile.txt","w");<br />
fwrite(szText,strlen(szText),1,pFile);<br />
fclose(pFile);
