Re: VC++ Toolkit 2003 warning message

9-Jun-08 22:45

When I compile the project, there are some linking warnings like:

"libcmt.lib(mktime64.obj) : warning LNK4099: PDB 'libcmt.pdb' was not found with 'C:\Program Files\Microsoft Visual C++ Toolkit 2003\lib\libcmt.lib' or at 'c:\Documents and Settings\member\desktop\MyProject\Release\Source 0.31.84\Release\libcmt.pdb'; linking object as if no debug info"

Is this warning not a problem or should I fix this?

Thanks,
Suman

Libcmt is a Microsoft library for multi-threading. .PDB files contain debugging information. It looks like the debugging information for libcmt can't be found by the linker.

The first thing to try is to search your hard disk for libcmt.pdb. If you find it, add its folder to the paths searched by the linker (or copy it to a place your linker can find it).

If you're not using multi-threading, turn it off so the linker won't look for this file.

Hi,

I keep reading articles that says I can use this code to navigate activex webbrowser on a dialog

BOOL Ctry7Dlg::OnInitDialog()
{
CDialog::OnInitDialog();

SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon

// TODO: Add extra initialization here
/******************************************/
COleVariant varEmpty;
m_wb.Navigate2("http://www.google.com",
&varEmpty,
&varEmpty,
&varEmpty,
&varEmpty);
/******************************************/

return TRUE;
}

but everytime run the code, I woul get this error:

error C2664: 'CWebbrowser2::Navigate2' : cannot convert parameter 1 from 'const char [34]' to 'VARIANT *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

can someone help me out here ??? Thanks

CreateThread parameter

rp_suman9-Jun-08 22:23

What is the use of CreateThread()function's last parameter "LPDWORD lpThreadId
".

Can we give some user defined value to this parameter?

In most of the programs some variable of type DWORD is declared and passed without initialization, is it no problem?

Taken from MSDN:
A pointer to a variable that receives the thread identifier. If this parameter is NULL, the thread identifier is not returned.

It means that it an "outgoing" parameter: you pass the address of a DWORD in which the thread Id will be stored. So, there's no problem in passing an uninitialized DWORD because it won't be read by the CreateThread function.

Open a debug view while opening a document

I occasionally use it in logging data if I'm tracking what various threads are doing. It's a little easier on the eyes than using the thread handle.

Hello,

I have a problem with opening a view, while opening a document (MDI).

What i do is I have a configuration file and when i read it, i can open a debug view (richtextview) and see the details about the configuration. I can import as many as configuration files i want. I can also open a document attached with a configuration file, but cannot open the debug view Smile | :)

BOOL Test::OnOpenDocument(LPCTSTR lpszPathName)
{
	if (!CDocument::OnOpenDocument(lpszPathName))
		return FALSE;

	CMainFrame* mainWnd = (CMainFrame*)AfxGetMainWnd();

	// Testing debugwindow open
	mainWnd->OnNewwindowDebugwindow();

	Log().inform("Hello !",getDebugWindow());
}

In above code, the mainframe creates a debug window, and getDebugWindow() just finds the debug view if there is any, and in the OpenDocument, it always returns NULL. the question is how i can create a view while opening a document?

CDebugWindow* Test::getDebugWindow()
{
	if(debugWindow==0)
	{
		POSITION pos = GetFirstViewPosition();
		CView* pView=0;
		bool found=false;
		while (pos != NULL)
		{
		  pView = GetNextView(pos);
		  if(pView->IsKindOf(RUNTIME_CLASS(CDebugWindow)))
		  {
			  found=true;
			  break;
		  }
		  // pView->UpdateWindow();
		}   

		if(found)
		{
			debugWindow = (CDebugWindow*) pView;
			return debugWindow;
		}
		else
			return 0;
	}
	else
		return debugWindow;

}

Thanks in advance.

Weird windows problem

Hello, I have a weird problem regarding the deleting of a folder.

I'm trying to delete a folder using this code

            TCHAR exeDirectory[MAX_PATH];
GetCurrentDirectory(sizeof(exeDirecotry) - 1, exeDirectory);
CString szStoreFolder;
            szStoreFolder.Format(_T("%s\\td10"),exeDirectory);
                        ......
                     SHFILEOPSTRUCT op;
    op.pFrom = szFolderName;
    //op.pTo = _T("");      //will be ignored
    op.wFunc = FO_DELETE;
    op.fFlags = FOF_SILENT | FOF_NOCONFIRMATION;
    op.fAnyOperationsAborted = false;
    op.hNameMappings = NULL;
    int er= SHFileOperation(&op);
    _tprintf(_T("Eroare %d "),er);

The problem is that it doesn't work every time.
It depends on the exeDirectory name and on the folder name (the folder that I'm trying to delete)

For instance if the exeDirectory is TEST and the folder name is Td10 it doesn't work. If the exeDirectory is ZIP_OPTION and the folder name TD10 it works. If the exe folder is TEST and the folder name is TemporaryData it works but now for the ZIP_OPTION folder it dosn't work.

I made a debug and the szFolder contains the correct path.

I've got the error 1026.

I tried to take the path with CFileFinder but still the same problem appears. I tried also to take the short folder name but it the same. I do not know what to do.

Any help or advice would be appreciate
Tnx

Why are you using GetCurrentDirectory()?
I don't know the rest of your code but there is a chance that the current directory changes after a recursive deletion with SHFileOperation or elsewhere in your code.
Also, you are mentioning 3 different variables for the path: "szStoreFolder", "szFolder" and "szFolderName". Very confusing.

problem solved
You should use the relative name to the current folder and the short name of the folder DOES NOT WORK WITH LONG FOLDER NAME.

I think your problem may actually be that your szStoreFolder is terminated only with a single NULL character and it should be terminated with double NULL characters.

MSDN[^]says to use fully qualified path names (not relative) - this allows the files/folders to be moved to the recycle bin.

Hope that helps.
