Im My project I have a udp server program running in Console VC++ application and I have to open telnet with a particular ip address in run dialog and then I have to type in some data in telnet so that I am receiving some data in udp server console application.Here the telnet acts as Client and Udp Console application acts as Server. Now I have to automate the telnet application in my project so that there is no manual entry of data in telnet. I have open the telnet with the particular ip address and type the data automatically via VC++. Can anyone suggest me some ideas rtegarding this.

CIPAddressCtrl *ip = (CIPAddressCtrl *)GetDlgItem(13);
ip->GetAddress(dwIPAddress);
13 is a control id that was i created dynamically
|
|
|
|
|
What is the problem ?
Did you check with your debugger that ip is a valid pointer before calling GetAddress ?
|

Check if the control identifier (13) was already assigned by AppWizard to any other control.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Whats return value in ip ?
|
|
|
|
|
I want to get a value from dynamic ip address control for that purpose i wrote this code
CIPAddressCtrl* ip = (CIPAddressCtrl *)GetDlgItem(13);
ip->GetAddress(dword);
|
|
|
|
|
How do you make this control?

Unless , you are having the control with id 13, nothing wrong with code. Though, I would have used dynamic_cast , instead of c-style cast.
prathuraj wrote: ip->GetAddress(dwIPAddress);
If ip is non-null and controll retunrned in previous statement is of type CIPAddressCtrl, there should not be any problem.
Can you specify, what problem you are facing.

ip->GetAddress(dword); Access violation error occured at this line

Because ip is invalid.

As sated in one of previous post, make sure, id 13 is assigned to control you are talking about.

control id is correct.but pointer is null.what i do further

Try this code instead (run in a debug build):
CWnd *pWnd = GetDlgItem(13);
ASSERT(pWnd != NULL);
ASSERT(dynamic_cast<CIPAddressCtrl*>(pWnd) != NULL);
CIPAddressCtrl *ip = static_cast<CIPAddressCtrl*>(pWnd);
If the second line asserts in a debug build the id is wrong.
If the third line asserts in a debug build the CWnd returned was not a CIPAddressCtrl and your cast is in error. Try adding a member variable (using ClassWizard in MSVC6); this step makes calling GetDlgItem unnecessary. If this line fails to compile enable RTTI (just in the debug build) and try again.
If the fourth line fails to compile CIPAddressCtrl is not derived from CWnd.
Don't use C-style casts!

Typically, the wizards assign control IDs starting at 1000 - perhaps the ID you chose (13) is actually some other control that has been assigned by Microsoft.
It could be that by simply changing your ID (perhaps to something like above 1000, you may be ok as long as that ID isn't used elsewhere in your project.
Hope that helps.

How to check if a valid document file is loaded in SDI application?
Actually I want to do some actions only after a file is opened. and also want to enable/disable filemenu save, save as submenus and save tool bar button.
Any suggestion?
Thanks

Hi,
loaded with Serialize () or loaded with CFile open and read?
And what do you mean with "valid"? If your program has an extension, it would load only files with this extension, and the serialize () already has some checking functions that says "this file is not valid" or "error by loading"
Please explain yourself a bit more
Greetings.

i'm having two dialog boxes and a formview..now i want t combine all these in a single view..that is the resultant application should contain the formview and one dialog bix at side of form view and another at the down so that if we want we can close those dialog boxes as in vc++ editor(msdev)..,

Please help me by ur suggestions..thanx n advance..
P.S:All the dialogboxes nd formview are seperate programs...

Hi,
why don't you try with a splitter window and 2 CFormViews? Or a DialogBox in NonModal message that you change the size and position in its OnInitDialog () with SetWindowPos () without caption and frame if you want (you can change this in resource editor or using WS_ styles and flags.

Hi mirraa,
actually you can close all the opened windows/dialogs in one touch. For example, in my app (MDI in VC++ 6) I have one CScrollView as MainView and up to 48 CFormViews for each element I want to introduce its parameters. When I close one SecondaryView I close it, and when I close the MainView I close ALL the others. I do this with:
BOOL CMyDoc::CanCloseFrame(CFrameWnd* pFrame)
{ int nError = 0;
CView* pFrmView = pFrame->GetActiveView ();
if (pFrmView->IsKindOf (RUNTIME_CLASS (CFormView)))
return TRUE;
POSITION pos = GetFirstViewPosition ();
while (pos)
{ CView* pView = GetNextView (pos);
if (pView->IsKindOf (RUNTIME_CLASS (CFormView)))
{ CFrameWnd* pTempFrame = pView->GetParentFrame ();
if (pTempFrame)
pTempFrame->DestroyWindow ();
}
}
return CDocument::CanCloseFrame(pFrame);
}
The only difference with the DialogBoxes is that you don't have this list for opened Views in Document. But you can also made it by yourself. Just create a CWnd* dlgArray [MAX] or hWnd dlgArray [MAX] and, in every DialogBox, take a pointer (or a handle, whatever you like more) to the opened DialogBox in the OnInitDialog. Afterwards you can close them as well with a call to DestroyWindow, CloseDialog or other functions like those.
Greetings.
