The RegisterTypeLib(...) function can be used to register Type Library information (as well as a newer function that I cannot remember off the top of my head) - you can write a little app to use it.
However, it sounds like your problem is that the underlying COM object(s) DLL is not registered. I would start with finding that DLL and running RegSvr32 on it.
Peace!

Ista wrote: DET.TLB Its a type library
But, when I use it I get the error
Use it? How?
A .tlb file contains a description of interfaces and other types defined in a .idl or .odl file that is compiled with the MIDL compiler.
The typelibrary (the .tlb file) could be included in the distributable binary, e.g. an ActiveX control, as a resource; or it could be distributed as stand alone file.
Either way it's tightly connected to the binary that it describes.
Ista wrote: I thought maybe if I create a dll from the tlb file, I could then use it
Think of the type library as a header file. When you've had that thought I assume you realize that you cannot compile a header file and build an executable application of it.
We "use" the type library when we add a library to the project, it could be a DLL, a COM server, an ActiveX control etc.
What happens here is that somewhere ::CoCreateInstance() is called and asked to create an object that has not been registered, at least not yet.
The cure for this is naturally to register the object/server.

Well what Im trying to, is Open a file ( classic asp ) and go to a specific line number. This is all done in InterDev.
Opening the file is easy "devenv.exe filename.asp"
But I need to go directly to a specific line number. So I thought I could link the library and Just use the COM to open the file and use the GoTo method to do my work.
So, in the VS2005, I create the reference. IThe environment creates the wrapper DTEClass(). ( file DTE.tlb in your IDE folder )
I instantiate it and but, I get this class not registered type error.
Do you have any ideas?

In what way are these questions related to the forum topics: VC++ and MFC? 
I don't know anything about InterDev, which I suspect is crucial to be able to help you.
Regarding COM the simple fact remains: the server you're trying to use, one way or the other, has not been registered hence you cannot use it.
Whether this is something that gets installed together with InterDev or not I cannot tell you.
Have a look in the registry under the HKCR\CLSID and if you cannot find the key
{3C9CFE1E-389F-4118-9FAD-365385190329} the DTE server has not been registered.
This is the class id of the DTE for VC7 that I've found in the typelib Dte.olb.
You can also use OLE/COM Viewer to lookup interfaces/typelibs/servers that are registered.

Well. I just wanted to use the COM to open it up. I got it to work with versions 7.0, 7.1, 8.0.
I used the OLE viewer to find it, but it's no where to be found.
Maybe its not publicly creatable or something.
So I give up. I can open it, and just use SendInput to manipulate it.
Thanks, for helping tho. I've been doing .NET for so long, I forgot most of the COM rules.
Thanks,

I've had the same problem. I just wrote a wrapper in VB6 and used that dll instead.
If you really hate VB (like I do  ) you can look into the
Interaction class which is able to call CreateObject and CallByName functions. I found this not so easy, but in my test case it worked fine except for the calls where a parameter was passed by value. (That's why in the end I resulted in VB6)
Hope this helps.
Coulda, woulda, shoulda doesn't matter if you don't.

Yeah. I absolutely hate VB! lol
SO I used The Interaction namespace to use create object. That works fine.
But, I just dont know the Prog ID for VisualInterdev.
I'm trying to automate some tasks, so I dont have to look at VB or classic asp more than I have to. It's like the plague to me.
If you know the prog ID, your my hero. I searched with every tool imagineable and no luck

It's somewhere in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Classes
You could do a look on the filename (without extension)
if OK you should have a Default string with a name and an AppID key with a GUID.
(eg. If your file is called yourname.tlb do a search on yourname under HKEY_LOCAL_MACHINE\SOFTWARE\Classes. Hopefully it will come up).
I didn't found how it linked with the tlb file though.
Good luck.

Hi.
In the debug window of VS, when I run the project, cames a string like this:
Ecception first-chance at 0x066d4931 in MyProg.exe: 0xC000001D: Illegal Instruction 
(Together with the lines that tells that the DBG files are not founded)
But it is not linked to any line of my code!
Is there a way to find correct this warning?
Thanks.
Cheers,
Russell

 mmm....
It is displayed 1 seconds before that the main window is displayed.
At that point of the execution I haven't used any pointer , I think.
Thanks anyway
Cheers,
Russell

You can use your debugger to narrow the problem. The call stack is also very usefull to find which of your function caused the crash.

It cames when

Probally a bad dll of the VTK toolkit

I tried all what possible in VC++ , or windows to find device context
I want to start thread for engine simulation. but I have to pass the dc to my
function because it is generic class and not from mfc. what to do in this case.
or please let me know how to get view window from the generic class.
here is my code.
UINT CMy5CYLINDERView::ThreadFunc(LPVOID pParam)
{
CWnd *cwnd,*cwnd1;
cwnd1 = cwnd->GetWindow(1);
CDC* pDC = cwnd1->GetDC();
simulate* eng = (simulate*)pParam;
eng->nextpos(pDC); // program compiles on run gives access violation.
return 0;
}
void CMy5CYLINDERView::support()
{
FireCylinder();
for(int ii = 0;ii <= 3;ii++)
{
x[ii] = AfxBeginThread(ThreadFunc,(LPVOID)&engine[ii]);
}
}

i think your problem is cwnd1 = cwnd->GetWindow(1); whats value cwnd(CWnd *cwnd)

the reason why we are making a thread static because of to access the local resource of the class.
what u had done in the code is abosolutely wrong let me point out one of them
shivditya wrote: CWnd *cwnd,*cwnd1;
cwnd1 = cwnd->GetWindow(1);
In the above statement, cwnd* is not an initialized pointer. so u wont anything from there.
shivditya wrote: cwnd1 = cwnd->GetWindow(1);
This one something seems wrong. what u meant by GetWindow(1)?
it is better u pass this pointer the the function or make it accesseble trough some global static pointers.
i.e
static pszWindow; // declare as static member variable
static CMy5CYLINDERView::pszWindow = NULL; // initialize it globally
on Initial update, update this value with this pointer. then u can access it at the thread function
CMy5CYLINDERView::pszWindow->GetDC();
there is one more option.
define a structure that contains all information u need at thread
the definition may goes like this
typedef struct
{
CMy5CYLINDERView* pView;
Engine* pData;
}MyThreadParam;
now u "allocate memroy" (dont pass local variable) for the type of structure and fill with required informatio and pass to the thread param
at thread function type cast and use it.

This highlighted line gives error as pszwindow is not object of CDC
its really problem beacause this thread function is static and it restricts a lot

You are using cwnd but it was never initialized....
The DC of which window do you want to get?
Is eng is part of that window?
If so , try using this code:
UINT CMy5CYLINDERView::ThreadFunc(LPVOID pParam)
{
YourWindow *wnd = (YourWindow *)pParam;
CDC* pDC = wnd->GetDC();
wnd->eng->nextpos(pDC);
return 0;
}
With best regards,
Eli

YourWindow *wnd = (YourWindow *)pParam;// You should pass the handle of the window as pParam
Here what means YourWindow
Beacuse I am able to get the active window I am not able to get device context.
will you please explain me what you mean by your window.
I tried long journey of HWND hwnd = :: GetActiveWindow()
then CDC tempdc = (CDC*)( ::GetWindowDC(hwnd));
but it also proved hopeless.

Hi
I am popping a default mail client with an attachment for sending the mail in my application.I used a dll which inturn used Mapi.I could successfully popup the default mail client when Eudora,Outlook express are set as default mail clients but when i set MSOutLook 2003 as default i could not.
Any Suggestions or links would be useful for me.
Thanx

A CWnd based class creates a popup window:
BOOL b=CreateEx(0,0,0,WS_POPUP|CHILD,rc,pMum,100);
in XP, the call failed, by in 98 and other OS, the call is OK.
how to solve the problem for XP?

Can you be more specific do you get error
whitesky

|
|

|

BOOL o=CWnd::CreateEx(0, AfxRegisterWndClass(0), "CTest1", WS_POPUP, 0,0,0,0, NULL, 0);//return 1
