I have both Visual Studio 6.0 and .NET (2003) versions installed on my PC. I am running an application (compiled for debug but not running under the debugger) and it throws an exception. The OS picks .NET as the debugger but I would like it to pick VC++6.0 as the debugger. Where is this setting?

I am not sure of the setting but I would say that I have installed .net 2003 just to debug my vc6 applications with the .net debugger. As is a lot better than the one with vc6 especially if you want to do remote debugging. One way to use the .net debugger is to load your project with it .net and let it upgrade to .net then exit. It will create a .sln and .vcproj for .net to load, don't worry it will not trash your .dsp or .dsw files so you still can compile and develop with vc6. I do this all the time.

I'm in case that function returned for me JPEG file data in CString.
so I write the CString data to IStream Object and then save the file but I'm
getting InvalidParameter , i do not know why? here is code snippet
Write(CString image, int len)
{
CLSID encoderClsid;
GetEncoderClsid(L"image/jpeg", &encoderClsid);
LPBYTE lpBits = (LPBYTE) GlobalAlloc(GMEM_MOVEABLE, len);
IStream *pStream;
HRESULT res = ::CreateStreamOnHGlobal(lpBits,FALSE,&pStream);
LPTSTR sImage = image.GetBuffer(len);
pStream->Write(sImage,sizeof(sImage),NULL);
LARGE_INTEGER li;
li.QuadPart = 0;
res = pStream->Seek(li,STREAM_SEEK_SET,NULL);
if(SUCCEEDED(res))
{
Image *jpgImage = Image::FromStream(pStream);
jpgImage->Save(L"C:\\myImage.jpg",&encoderClsid,NULL);
//here Save return InvalidParameter , WHY? any suggestions?
}
}

All items are grayed out, why?
void CMyFrameWnd::OnRButtonUp(UINT nFlags, CPoint p)
{
CMenu menu;
menu.CreatePopupMenu();
menu.AppendMenu( MF_STRING | MF_ENABLED , 700 , "Zoom All" );
menu.AppendMenu( MF_STRING | MF_ENABLED , 701 , "Properties" );
ClientToScreen(&p);
menu.TrackPopupMenu(TPM_CENTERALIGN,p.x,p.y,this,NULL);
CFrameWnd::OnRButtonUp(nFlags, point);
}

Do you have a handler function for menu items 700 and 701?

No I am overriding OnCommand()
For CWnd's this seems to be enough - maybe for CFrameWnd's it's not enough?
|
|

MFC's framework will disable menu items for which a handler has not been provided. There is no way for it to know that you are handling menu item requests from within OnCommand().

So I shouldn't override OnCommand(), instead I should create a handler?
ON_COMMAND_RANGE( 700 , 701 , OnMenuCommand )
afx_msg void OnMenuCommand ( UINT nID )
I just wonder - why is OnCommand() virtual then?

You can add onupdatecmdui handlers for each id and then use oncmommand, I do this a lot.

That's how I would proceed.

It has its purpose. My most recent use of it was on a property sheet. I needed to handle the clicking of the OK button.

Thank you for your help, it works with the handler - still I wonder, still I wonder..

I'm using a class derived from CHtmlView as listview in an internal Folder
Browser of my application.
Exist a facility to hide the left blue task pane (if user have activate this
feature in Folder Options)?
Another fine feature will be, to set the "list" as active default view in my
application (may be the user has set "icon" as default). Any idea?
Thx for help

Hi,
I've created a dll (C++) containing several functions, which are used inside an Excel-VBA-Project via dll-calls.
What I want: when the dll is loaded into memory (i.e. when one of the functions is executed first time), a general function should be executed (purpose: check licence information etc.).
Is there an event, which is triggered when the dll is loaded ?
TIA M.

BOOL WINAPI DllMain(
HINSTANCE hinstDLL,
DWORD fdwReason,
LPVOID lpvReserved
);
fdwReason -> DLL_PROCESS_ATTACH -> The DLL is being loaded into the virtual address space of the current process as a result of the process starting up or as a result of a call to LoadLibrary. DLLs can use this opportunity to initialize any instance data or to use the TlsAlloc function to allocate a thread local storage (TLS) index.

Why do you want to pass a CStatic variable to a member function ??

I'm going to patent thought. I have yet to see any prior art.

(Off the top of my head guess)
CStatic might not have a copy constructor.
Try declaring the function as
void FuncX (CStatic &MyStatic);
- or -
void FuncX (const CStatic &MyStatic);
