Thanks. I am really ambitious and I really want to be an expert when I am older in various aspects of computing. I am learning bits of networking from my dad and I am teaching myself web programming and now I would like to learn this

hiho@ll

i'm using the outport source to export contact and appointments

my problem is i need to know a unique ID for a contact or appointment, to know if a contact or appointment has changed

outport uses InvokeHelper(0xf051, DISPATCH_METHOD, VT_EMPTY, NULL, parms, (LPCTSTR)fullname, &type);
to tell outlook to save the contacts or appointments in seperate files
(it's the same as if you do File->Save as) in outlook

the problem is it doesn't save a ID
so anybody knows how to determine the ID for a appointment and/or contact?

thx@ll

Receiving text strings over Bluetooth using a C-program and Visual C++

Hi, I am trying to use a C-program to read a virtual com port. Attached to this com port it is a Bluetooth Adapter(D-Link DBT 120). I am sending text strings from a bluetooth-unit and over to the Bluetooth adapter. I do manage to read the text strings with HyperTerminal, but I don't manage to read the text strings with C. I am using CreateFile to open the com-port, DCB to set the preferences(BaudRate, parity etc.) and ReadFile to read the Com-port. Anyone got an ide of what I can do? Thanks in advance!

Hye.
i write this code to get inpur from user such as ram and hard disk capacity as integer type using structures. After that i want to create a file in which i want to save that data. In the code below it is getting input from user but not creating file Confused | :confused:

. Plz tell where is my mistake.
Code is:

#include <conio.h>
#include <iostream.h>
#include <fstream.h>

void main()
{
struct computerspec
{
int ram;
int hdisk;
}compuspec;

cout<<"Enter the RAM capacity"<<endl;
cin>>compuspec.ram;

cout<<endl;
cout<<"enter the="" hard="" disk="" capacity"<<endl;
cin="">>compuspec.hdisk;

cout<

i dont see any problem in your code.
It must be working fine and must crate the file.

Check the file
1) if you are directly running the .exe, at the location of the exe file.
2) if you are executing from the vc projecy, then the file will be created at the location of workspace and project files i.e. where .dsw/.dsp exists.

Does this statement create the file if it does not exist?

Yes it does creates the file, if the file does not exist.

The actual syntax is

file.open(filename, open flags, protection specifications).

The default open flag is ios::out which creates the file if it does not exists. To avoid the file creation if it does not exists another flag ios::nocreate is used.

Hi all,
I want your help to write a program in C++ or C that could convert the words into numbers.

for example:
Input: threehundredandthirtyfour
should give an output:334

Thanks in advance. Looking forward to hear from you all.

I have pretty simple code

void ReadDeviceThread( void *lparam )
{
Sleep(2000);
((ProgressDialog *)lparam)->EndDialog(IDOK);
}

void CMainWindow::OnReadDevice()
{
static ProgressDialog pd;

_beginthread(ReadDeviceThread, 0, &pd);

pd.DoModal("Initialising read from device");
}

The app crashes at user32.dll (win XP, VC++ 6.0, SP6.0) after call of EndDialog. Specifically it crashes after calling ::EndDialog at the end of the EndDialog routine.

void CDialog::EndDialog(int nResult)
{
ASSERT(::IsWindow(m_hWnd));

if (m_nFlags & (WF_MODALLOOP|WF_CONTINUEMODAL))
EndModalLoop(nResult);

::EndDialog(m_hWnd, nResult); // after this line app crashes at USER32! 77d562cf()
}

Could anybody please help me with this problem. What's wrong with my code.

Thank you

I do not know if this will work.
Anyway, try this:
((ProgressDialog *)lparam)->PostMessage(WM_COMMAND,IDOK);

this is this.

Thank you khan++ - PostMessage has fixed the problem.
I still wondered what was wrong with EndDialog??!!

hi I have created mfc dialog based application.IN that i have set the bitmaps on dialog box and i am creating dyanmic buttons on that . I am able to see the dynamic buttons but the buttons which i have pasted on dialog box on the bitmaps are not seen.
When i run the application I can see the dialog with bitmaps an dynamic buttons but the buttons already on dialog are seen when i click on dialog box or move it.

It means it is the problem of re-painting.I tried a lot but was not successful. Can anyone help in solving the same.

Best Regards
jhon

.....i dunno if thiz will help but try thiz out......
each button is derived from a Cwnd class,so we manually put in the code to show the button window as the topmost window.....
and put the code in ur OnInitDialog() function,

//get the pointer to the button thru the button id,
GetDlgItem(IDOK)->SetWindowPos(&CWnd::wndTopMost, 0, 0, 0, 0,SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE);

hope that solvez ur problem.....

Try repainting the buttons in OnEraseBkgnd() after drawing the background for the main dialog.
If that fails, try repainting the buttons in OnPaint();

this is this.
