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

simon

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?

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.

So how exactly does this describe LNK4089? His post plainly asked what it was, not how it could be circumvented.

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 />
}
