Hi

I have solved my problem by making my control handle the WM_GETDLGCODE and forcing it to return DLGC_WANTARROWS|DLGC_WANTALLKEYS|DLGC_WANTCHARS;

Still to discover if this has further consequences.

Why don't you simply extract the date out of the table, convert it to the format of the date-time control (so, invert it) and put it in the control ?

fetch the date from the table . You will be having the date somewhere in the string. Now extract that date by tokenizing or whatever method you choose and than format the date using
CString::Format();

Somethings seem HARD to do, until we know how to do them.

Here is the code ... which converts the date extracted from the mysql and put it into DTPicker control.

CString strTestDate("2006-05-05");
SYSTEMTIME currTime;
GetSystemTime(&currTime);
sscanf(strTestDate.GetBuffer(0),"%u-%u-%u",&currTime.wYear,&currTime.wMonth,&currTime.wDay); 
strTestDate.ReleaseBuffer();
m_DateTime=CTime(currTime);;
UpdateData(0);

Where strTestDate is fetched date from mysql. and m_DateTime is the control variable of the DTPicker control of type CTime.

here GetSystemTime is required to get the correct format result of the date picked from the mysql table.

Hope you are looking for same.

CString s;
LPCTSTR st;
s += CString(st);

in fact, I thought s += st would work.

Here is another way how we can append the LPTSTR to CString

CString strTest("Hello");
LPTSTR lpStr=" World";
strTest.Insert(strTest.GetLength(),lpStr);

We can directly add the strings using += operator as it overloaded in CString class

have you ever tried the simplest way (with + or += operators) ?

CString str = "hello ";
str += "world !!";

Streaming Video in MFC or any language [modified]

Does anyone know how to do streaming video feeds with MFC or any other programming style? I'm working on a senior design project for school and we'd like this to be a part of the application I'm designing, the only problem is that I've never done anything like streaming video before. Any help would be greatly appreciated. Confused | :confused:

I'm making a WTL style DLL with an opening dialog, but i also need to be able to browse files from that DLL. I've triedto use both CFileDialog and OPENFILENAME structure, but neither is working, even though they are working fine in the executeable Confused | :confused:

OPENFILENAME:

/*OPENFILENAME ofn;       // common dialog box structure<br />
	char szFile[260];       // buffer for file name<br />
	HWND hwnd;              // owner window<br />
	//HANDLE hf;              // file handle<br />
<br />
	// Initialize OPENFILENAME<br />
	ZeroMemory(&ofn, sizeof(ofn));<br />
	ofn.lStructSize = sizeof(ofn);<br />
	ofn.hwndOwner = hwnd;<br />
	ofn.lpstrFile = szFile;<br />
	//<br />
	// Set lpstrFile[0] to '\0' so that GetOpenFileName does not <br />
	// use the contents of szFile to initialize itself.<br />
	//<br />
	ofn.lpstrFile[0] = '\0';<br />
	ofn.nMaxFile = sizeof(szFile);<br />
	ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";<br />
	ofn.nFilterIndex = 1;<br />
	ofn.lpstrFileTitle = NULL;<br />
	ofn.nMaxFileTitle = 0;<br />
	ofn.lpstrInitialDir = NULL;<br />
	ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;<br />
<br />
	if(GetOpenFileName(&ofn) == IDOK)<br />
		SetDlgItemText(IDC_EDIT1, ofn.lpstrFile);

CFileDialog:

CFileDialog dlg(TRUE);<br />
	if(dlg.DoModal() == IDOK)<br />
		SetDlgItemText(IDC_EDIT1, dlg.m_szFileName);

What does 'not working' mean ? You get a crash, it doesn't compile, it does not do what you expected (and explain what you expected and what you get instead), ...
We cannot guess what's happening.

Yes, the windows file browsing dialog never appears, focus turns to nothing and the whole application is locking.

Since your application seems to be a non-MFC one, I suppose that CFileDialog does not work because of some missing initialization stuff, required by MFC. Maybe you should call AfxMainInit once in your DLL?

The variant without MFC, based on GetOpenFileName, probably requires a previous call of InitCommonControlsEx initialization function.

GetOpenFileName actually returns a BOOL value, not a code which can be compared with IDOK. I think you should use a simple if. If it returns FALSE, you can see what is the problem using CommDlgExtendedError:

if(GetOpenFileName(&ofn))
{
    SetDlgItemText(IDC_EDIT1, ofn.lpstrFile);
}
else
{
    DWORD error = CommDlgExtendedError();
}

Then investigate the error code, or tell us.

This might be the problem normally we specify the filter as follows (seperated with "|" and ends with "||"
e.g

char* pszeFilter = "*.*|*.*|text|*.txt|Music|*.mp3||";

The separator depends on approach used. If the filter is set in OPENFILENAME structure directly, then '\0' must be used. If the filter is set in the constructor of CFileDialog object, then '|' is used. CFileDialog will convert it to '\0'.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
