Hello, I'm using VC++v6.

When I'm debugging, I cannot view any variable values in the watch window when I step through e.g.

NAME m_PathName
VALUE CXX0017:Error: symbol "m_PathName" not found

The variable is in scope and initialised, and i'm definately in debug mode. My variables window is also empty. I have used them successfully before but I can't figure out why not now.

Can anybody help, thanks,
John

Make sure you have the "Debug info" option switched on. If that doesn't work, exit VC++, delete all .ncb, .opt, .plg, .pch and .pdb files in your project and try again.

Hi,
I believe the MSDN library discs have a sample called DYNAMENU that shows how to dynamically add items to a menu.

Hope that helps,
Lan

Use InsertMenu()

BOOL InsertMenu(
HMENU hMenu, // handle to menu
UINT uPosition, // item that new item precedes
UINT uFlags, // options
UINT_PTR uIDNewItem, // identifier, menu, or submenu
LPCTSTR lpNewItem // menu item content
);

That was a joke. You see, the person who wrote "Send Source Code!!!!" was making demands on CP members as if he were King or President. Similar to "You must do this. I command you." So, the joke was that you did not give him what he commanded. Sorry if I was not clear. Rose | [Rose]

How to capture the message of a subcontrol which was created dynamicly?

10-Jun-02 4:38

I create a ListBox in a Dialog dynamically!I want to capture
the message LBN_SELCHANGE of the control ListBox,I create it like this:
m_ListBox.Create (WS_CHILD|WS_VISIBLE,rc,this,IDC_LIST_BOX);//CListBox m_ListBox
And I use the following code to check if the dialog capture
the message:
LRESULT CMyDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
if(message==LBN_SELCHANGE)
{
AfxMessageBox ("LBN_SELCHANGE");
}
return CDialog::WindowProc(message, wParam, lParam);
}

But to my surprise,I found that it can capture the mesage only once,it occured at the begin of the program.after that ,it can't be captured.
How can solve the problem!
Thank you!

Don't look at me in that way!

Do you know how should i test if a directory exists in the file system, or a file?
Is that an article on CP regarding this subject?

#include <io.h>

if (_access(dir, 0)==0)
 then it exists

is this a better method that using CFindFile? does the _access function verify the user has access to the path as well, instead of just that it exists?

with mode 0, _access only checks for existence. other modes can test for read/write access.

heres what i use..

BOOL CCommonFunctions::DirectoryExists(CString strPath)
{
	CFileFind finder;
	
	// check to see if path given has end slash, if not add it
	if (strPath.Right(1) != "\\") 
		strPath += _T("\\");

	strPath += _T("*."); // searching for *. returns only directories

	// start working for folders
	BOOL bWorking = finder.FindFile(strPath);
	if (!bWorking)
		return FALSE;

	finder.Close();
	return TRUE;
}

use it by saying:

if (!CCommonFunctions::DirectoryExists("C:\\Temp\\")
AfxMessageBox("ERROR!");

and for files..

BOOL CCommonFunctions::FileExists(CString strFilename)
{
	CFileFind ff;
	BOOL result = ff.FindFile(strFilename);
	if (!result) // file doesn't exist
		return false;
	
	ff.Close();
	return true;
}

use it by saying:

if (!CComonFunctions::FileExists("C:\\test.txt")
AfxMessageBox("ERROR!");

that should help.. if someone has a better written function let me know..

My applications HTML Help does not work when running under another account

I have a strange problem:

Because we need to run a process under another account (for COM+ rolebased security). To do so, we create a little startup application that displays a dialog where the user can enter its credentials. Then it uses the API call
CreateProcessWithLogonW to startup the real app. After this, our help does not work anymore. We use Windows 2000/XP with HTML help.

Does anyone have an idea?

Thanks,
Remon

An idea: Check the permissions on the HTML help directory and files.

Thanks for your reply.

It was much simpler. The default directory when running under another account was not the same (not the module directory). Therefore the helpfile could not be found. Cry | :((

Go to sourceforge.net and search for "HTTP proxy". There are several projects under work that may suit your needs.
