I think the file you have opened didnot get closed so First close the file using CloseHandle or fclose.

you need to create d on heap.

And for obvious reasons, need to delete it after use.

Hi
I am using CfileDialog, but i cant get it to display pointing to the correct directory

it seems to ignore the path that i pass

im using

TCHAR szFilters[] = _T ("Log Files (*.txt)|*.txt|All files (*.*)|*.*||");
CFileDialog dlg(TRUE, _T ("txt"), _T ("*.txt"),NULL, szFilters);
CString MyPath "c:\";
if (logPath.GetLength())
dlg.GetOFN().lpstrInitialDir = MyPath;

if (dlg.DoModal()==TRUE)
{
CString result = dlg.GetPathName();
ShellExecute(NULL, "Open", _T(result), NULL, NULL, SW_SHOW);
}

can anyone help

thanks

You can use from Data Member m_ofn In CFileDialog that you have access to parameters of dialogbox

String MyPath "c:\"; is invalid. '\' is the escape character, so if you want to print a \, you must specify '\\'

CString MyPath = "C:\\";

One last thing. if (dlg.DoModal()==TRUE) is not syntactically correct. CDialog::DoModal() doesn't return a BOOL (TRUE or FALSE). it returns the exit code specified in the dialog with the call to CDialog::EndDialog(). In general, it is the ID of the buttons pressed, so you should test your CFileDialog with either IDOK or IDCANCEL.

if (dlg.DoModal() == IDOK)

I think you are using OS XP or 2000, then try

dlg.GetOFN().lpstrFile = MyPath;

it will work

This is a syntax error.

What is logPath?

si_69 wrote:

Since GetOFN() does not exist with VC++ v6, I used m_ofn instead. Other than that, this code works fine. Do not use strcpy(), as you simply need to assign a pointer to an existing address.

How to get KeyPessed event from an editbox

gunner_uk200026-Sep-06 22:55

26-Sep-06 22:55

Here is my event handling code:

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, <br />
						 WPARAM wParam, LPARAM lParam)<br />
{<br />
	switch(msg)<br />
	{<br />
	case WM_CREATE:<br />
		Init();<br />
	case WM_PAINT:<br />
		PaintScreen();<br />
		break;<br />
	case WM_CLOSE :<br />
		DestroyWindow(hwnd);<br />
		break;<br />
	case WM_KEYDOWN:<br />
		if(wParam == 13){<br />
			ProcessCommand();<br />
		}<br />
	case WM_COMMAND :<br />
		if(LOWORD(wParam) == ID_COMMAND)<br />
			ProcessCommand();<br />
		break;<br />
	case WM_DESTROY :<br />
		PostQuitMessage(0);<br />
		break;<br />
<br />
<br />
	}<br />
<br />
	return DefWindowProc(hwnd, msg, wParam, lParam);<br />
}

This only works if the main window has the focus, so how can i check which key was pressed if the editbox (ID_EDITBOX) has the focus.

Ie so that if the user presses enter i can run the proccessing needed on it.

How would i go about using the EN_CHANGE notifcation?

As checking for it in the switch case does not work as the code is not executed when i key is pressed.

<br />
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, <br />
						 WPARAM wParam, LPARAM lParam)<br />
{<br />
	switch(msg)<br />
	{<br />
	case WM_CREATE:<br />
		Init();<br />
	case WM_PAINT:<br />
		PaintScreen();<br />
		break;<br />
	case WM_CLOSE :<br />
		DestroyWindow(hwnd);<br />
		break;<br />
	case WM_KEYDOWN:<br />
		if(wParam == 13){<br />
			ProcessCommand();<br />
		}<br />
		break;<br />
	case EN_CHANGE:<br />
		if(wParam == 13){<br />
			ProcessCommand();<br />
		}<br />
		break;<br />
	case WM_COMMAND :<br />
		if(LOWORD(wParam) == ID_COMMAND)<br />
			ProcessCommand();<br />
		break;<br />
	case WM_DESTROY :<br />
		PostQuitMessage(0);<br />
		break;<br />
<br />
<br />
	}<br />
<br />
	return DefWindowProc(hwnd, msg, wParam, lParam);<br />
}
