I can not, because I am using a derived class to embed my dialog class into the tab control, so I need to reflect the messages.
Thanks.

Define a message ID in the WM_APP range, like this:
#define UWM_SHOW_HIDE_MAIN_WINDOW WM_APP Then in your child dialog:
GetTopLevelParent().SendMessage(WM_APP, show_or_hide_flag); Or you could break it into two messages, one for showing and one for hiding. Handle UWM_SHOW_HIDE_MAIN_WINDOW in your main dialog's message map and show/hide the window accordingly.

Thanks Mike,
you are as helpful as always. I ran through all of your articles about WTL, but couldn't figure this GetTopLevelParent() out. Thank again.

I'm using VC 2005, and WTL 7.5. And I cannot for the life of me get intellisense to work with the WTL classes. Has anyone had any luck with this?
Cheers,

It's rather a glib answer - but use Visual Assist[^] - it's a bit pricey, but to be honest, I don't use Visual Studio without it.

Hi, I'm writing a C++ ATL/COM service on visual studio 20005, my client is written in vb.net also on visual studio 2005.
When I'm trying to call a dcom (on local machine) function the client gets an AccessViolationException.
I have two functions with the same parameters on my interface ,when I call the first function everything is ok and I get the exception only when calling the second function.
I used the attributed flag when I've created the atl class, and I've used custom interface and apartment threading model.
Here are some code lines from my h file:
[helpstring("method Read")] HRESULT Read([in] ULONG address, [in] USHORT dataSize, [in] USHORT stride, [in] USHORT partialDataCount, [in,out, satype("BYTE")] SAFEARRAY **dataBuff, [out,retval] LONG *result);
[helpstring("method Write")] HRESULT Write([in] ULONG address, [in] USHORT dataSize, [in] USHORT stride, [in] USHORT partialDataCount, [in,out, satype("BYTE")] SAFEARRAY **dataBuff, [out,retval] LONG *result);
STDMETHOD(Read)(ULONG address, USHORT dataSize, USHORT stride, USHORT partialDataCount, SAFEARRAY **dataBuff, LONG *result);
STDMETHOD(Write)(ULONG address, USHORT dataSize, USHORT stride, USHORT partialDataCount, SAFEARRAY **dataBuff, LONG *result);
Can any one help me? Please?
Thanks,
Orit

These doesn't help. You need to show, function implemention giving these access violations, and code how you are using it.

Thanks, I solved the problem by using dual interface instead of custom interface.
My recommendation: use dual interfaces (unless you have a good reason not to), especially if your functions use arrays, I've wasted a lot of time on this.

hi,
I created two ATL COM projects (Project1 and Project2). If I want to use a enum created in idl file of project1, in the idl file of project2, what are the steps that have to be followed. Please enlighten me.
Thanks in advance.

First off, I'm running Visual C++ 6.0. With the MFC CDialog class, if you want to provide context-sensitive help for your app, you just define a COMMAND_ID handler in the message map for the ID_HELP message ID. That way, when the user presses F1, the method pointed to in the COMMAND_ID entry in the message map is called and you can display your help app. Is there something similar in an CAxDialogImpl derived class?
|
|
|
|
|
The dialog gets a WM_HELP message when you hit F1.

Thanks, I'll check this out tomorrow.

How about CodeProject? ATL[^] WTL[^] STL[^]

For ATL and WTL, start here[^]

ATL, WTL and STL are unrelated to each other. They just heavily use templates. I would not invest too much into these outdated libraries.
|
|
|
|
|
er, WTL is a set of classes built on the ATL windowing classes.
STL is not outdated.

Hi,
I have to post a message froma thread that I have created and I cant seem to find the DefWindowProc that is usually in a MFC program, so how does one actually perform an action when a message is triggered.
I am completely new at ATL, any help would be greatly appreciated.
Thanks

IMO, it can be done differently. No need to create a server B. Just call your COM object like in the snippet below.
try
{
long lResult = DoIt();
}
catch(...)
{
// Just in case
LogError(_T("Unhandled exception occured.");
}
long DoIt()
{
long lResult = 0;
try
{
ComLibrary::IComLibraryPtr ipExt("Prog_ID");
lResult = ipExt->Main("SomeParam");
if (lResult < 0)
{
LogError("ComLibrary has requested a stop by returning a negative value %d.", lResult);
}
}
catch( _com_error& Err)
{
if (0x800401f3 == Err.Error())
{
LogError("Error creating ComLibrary. Invalid ProgID.");
}
else if(0x8007000e == Err.Error())
{
LogError("Error invoking Main. It is likely that the ComLibrary crashed.");
}
else
{
LogError("Error invoking ComLibrary.");
}
}
catch(...)
{
LogError("Error invoking ComLibrary. Received an unhandled & unknown exception.");
}
return lResult;
}
