I was hoping to stop the DTR/RTS, set to 0, before I actually need to control them. I wanted to build a different default configuration. I do use SetCommConfig down the line.
And yes, I hope someone will come up with a reason why they cannot be controled by this API. But it appears to be long shot here.
I think I found a workaround, not using DTR/RTS, but I need to test it.
Thanks for your input.

i have a string such that
hello
hi
good
i want to extract the values line by line....please help
|

What sort of string, and what do you mean by extract the values line by line? You could use one of the strtok[^] variants for a simple character array, or one of these functions[^] for a string.

i have a character array such thatb char buffer[100];
the values are stored like
cklvcmsdl
dclcm
dcpcc
i have to extract these values line by line and compare them with the input to find matching usernames
buffer contains the usernames

Well it looks like you need to use the first option I suggested.

That means the user names are separated by the newline character, you may use strtok as Richard already suggested or hand-craft a simple loop to collect all the names.

As CPallinial suggested, here is simple loop to collect all the names.
#include <iostream>
#include <algorithm>
#include <vector>
#include <string>
using namespace std;
char one_line_string[] = "hello hi how are you nice weather we are having ok then bye";
char seps[] = " ,\t\n";
char *token;
int main()
{
vector<string> vec_String_Lines;
token = strtok( one_line_string, seps );
cout << "Extracting and storing data in a vector..\n\n\n";
while( token != NULL )
{
vec_String_Lines.push_back(token);
token = strtok( NULL, seps );
}
cout << "Displaying end result in vector line storage..\n\n";
for ( int i = 0; i < vec_String_Lines.size(); ++i)
cout << vec_String_Lines[i] << "\n";
cout << "\n\n\n";
return 0;
}

Hi all,
I have a program that runs as a service somewhere on a server. It communicates with a console-type program (possibly on another machine within the network) by means of a messages file. The file is created by the service (because there may be multiple console programs running) However, the service is started by an administrator. Due to this, the console programs do not have access rights to the messages file. It works fine if I create the file manually (the service only creates if it does not exist) but if the file for some reason gets deleted, the consoles are no longer able to add their messages into the file.
Is there a way in which I can grant full control rights to all users from the service program after creating the file?
Anyone? Please?
Thanks in advance,
William

Sorry this doesn't answer your question, but I'd recommend instead you have a network group that has the create and write permissions and then ensure the administrator and other users are members of that group.

Which is indeed what I advised my clients. However, there are several clients using this software and if there is one thing I learned over the years: Sysadmins will ALWAYS have their own thoughts on how to organise and authorize their users!

Ah yes, clients, users and sysadmins. The nemesis of our existence. 
It might be possible at the folder level to allow full control to network access and to have that access flow to sub-folders. That might override the local adminstrator account when it creates the file.

Can somebody help in putting 2 tree view in one window in mfc
|
|
|
|
|
You can have two invisible windows as a container each one containing a single tree control. Place both of them in one window.
or write your own owner drawn control...

how can i have 2 invisible window under one single window???????
|

The main window should contain a CSplitterWnd. The panes of the splitter should contain you CTreeViews.

How can I close an document from another document ?
Is correct to call simply OnCloseDocument ? :
POSITION posDoc,pos = theApp.GetFirstDocTemplatePosition();
while(pos)
{
CDocTemplate* pDocTemplate = (CDocTemplate*)theApp.GetNextDocTemplate(pos);
posDoc = pDocTemplate->GetFirstDocPosition();
while(posDoc)
{
CDocument* pDoc = pDocTemplate->GetNextDoc(posDoc);
if(pDoc)
{
if(bSomeCondition)pDoc->OnCloseDocument();
}
}
}

This is unfortunately, not the correct way.
Two possible ways:
If I remember correctly CDocument is a CCmdTarget, you could post a message directly to the document:
pDoc->SendMessage(WM_COMMAND, ID_FILE_CLOSE, 0L);
This may or may not work (untested, unchecked)
Typically a document only has a single view...
As you already have a pointer to the document in question, you can use its GetFirstViewPosition() / GetNextView() functions. You could send a WM_CLOSE to each view.
If you vote me down, my score will only get lower

In did, I have only a view attached by document, but your code didn't function, I get follow error :
SendMessageA' : is not a member of 'CDocument'
|
|
|
|
|
While i can't tell you how to correctly do this, whenever you see a Windows member function starting with the prefix 'On', then this is an event handler, and should not be called directly. Best case it won't do what you expect, worst case it crashes your app. The purpose of event handlers is to react to events that have already occured, not trigger such an event.

Well, I turn problem into one simpler, but without solution for me : how is the right way to close an document from CMyApp ? I try in follow way, but I don't know if is correct :
void CMyApp::CloseAllDocuments(CDocument* pDocExcept)
{
POSITION posDoc,pos = GetFirstDocTemplatePosition();
while(pos)
{
CDocTemplate* pDocTemplate = (CDocTemplate*)GetNextDocTemplate(pos);
posDoc = pDocTemplate->GetFirstDocPosition();
while(posDoc)
{
CDocument* pDoc = pDocTemplate->GetNextDoc(posDoc);
if(pDoc != pDocExcept)
{
pDoc->OnCloseDocument();
}
}
}
}
here I want to except for closing down an specific document ...
|
|

|

I try that in follow way, witout success :
void CMyApp::CloseAllDocuments(CDocument* pDocExcept)
{
POSITION posDoc,posView,pos = GetFirstDocTemplatePosition();
while(pos)
{
CDocTemplate* pDocTemplate = (CDocTemplate*)GetNextDocTemplate(pos);
posDoc = pDocTemplate->GetFirstDocPosition();
while(posDoc)
{
CDocument* pDoc = pDocTemplate->GetNextDoc(posDoc);
if(pDoc != pDocExcept)
{
posView = pDoc->GetFirstViewPosition();
while(posView)
{
CView* pView = pDoc->GetNextView(posView); CFrameWnd* pFrame = pView->GetParentFrame();
pFrame->SendMessage(WM_CLOSE);
}
}
}
}
}

As I said, I can't really tell - it's been >15 years I last coded something like that, and while not much seems to have changed, my memory does fail me here. It seems a good idea to me to try close the view associated with the document, rather than the document itself. but I wonder, do you really have multiple views associated to your documents? Your code doesn't even try to close the first view it finds. Maybe you can try that before looking for more views?
On a sidenote, why do you even need to closee your documents manually? Normally this is something the framework does for you (which may be the reason why it seems to be so badly documented). Normally you have a GUI with one or more views to one or more documents, and when you close a view (e. g. by menu, or clicking on the [x] button), that view will be closed. When the last view referencing a document is closed, that document will be closed as well. And when you close the app, it will close all views. That's all in the framework already, no need for any extra code. In fact, it might even be a bad idea to close a document manually because it may confound the framework when it tries to do likewise.

You are right, I should try to close view ( viewes ) to be sure that the document is close. Thank you. I will let you you know what I've done.
|
|
|
|

I did it, now goes well, but now I close views not documents. Obviously, I learn something here. Thank you so much !

Dear Friends I have two mfc application. One is a dll and the other one is a client exe application. From the exe application I am trying to load the dll and launch the mainwindow of the dll.
For that in dll.....I have the view class there in view implementation file i am declaring a view pointer, like the code below
[code]
//RevolutionProjView.cpp file
CRevolutionProjView *view;
CRevolutionProjView::CRevolutionProjView()
{
view = this;
}
// The I am creating an extern C function by name runAppli like below.
extern "C" BOOL __declspec(dllexport) runAppli(void)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
view->ShowWindow(SW_SHOW);
return true;
}
[/code]
Now I have exe applicatioln where I want to launch the mainwindow of the dll above is given below.
[code]
void CClientRevProjDlg::OnBnClickedButton1()
{
typedef VOID (*MYPROC)(void);
HINSTANCE hinstLib;
MYPROC ProcAdd;
BOOL fFreeResult, fRunTimeLinkSuccess = FALSE;
hinstLib = LoadLibrary(L"C:\\Users\\DasmahapatraS\\Projects\\Bhagavan_Cadem\\RevolutionProj_OrthoGraphic\\debug\\RevolutionProj.dll");
if (hinstLib != NULL)
{
ProcAdd = (MYPROC) GetProcAddress(hinstLib, "runAppli");
if (fRunTimeLinkSuccess = (ProcAdd != NULL))
(ProcAdd) ();
fFreeResult = FreeLibrary(hinstLib);
}
if (! fRunTimeLinkSuccess)
printf("message via alternative method\n");
}
[/code]
With this my application mainwindow is appearing but immediately its crashing. Can anyone tell me whats going wrong. How can I launch the mainwindow of the dll ?? Please help me. Thanks Sujan
