If you're using accept, the second parameter is an optional pointer to a structure that contains source information.

Hi folks!
I'm working on a MFC project and i've got a question to make. The project i'm involved in, is a dialog based aplication. So, the Wizard took the first steps of the work. I'm basing the program on an example that has been created entirely programming, and it makes reference to a HWND handle variable that is necessary to pass to one of the methods.
The code is like this:
Code:
HRESULT CText::BlendText(HWND hwndApp, TCHAR *szNewText)
{
LONG cx, cy;
HRESULT hr;
CSubtitlesDlg dialog;
// Create a device context compatible with the current window
HDC hdc= GetDC(hwndApp);
HDC hdcBmp = CreateCompatibleDC(hdc);
// Write with a known font by selecting it into our HDC
HFONT hOldFont = (HFONT) SelectObject(hdcBmp, g_hFont);
// Determine the length of the string, then determine the
// dimensions (in pixels) of the character string using the
// currently selected font. These dimensions are used to create
// a bitmap below.
int nLength, nTextBmpWidth, nTextBmpHeight;
SIZE sz={0};
nLength = (int) _tcslen(szNewText);
GetTextExtentPoint32(hdcBmp, szNewText, nLength, &sz);
nTextBmpHeight = sz.cy;
nTextBmpWidth = sz.cx;
// Create a new bitmap that is compatible with the current
//window
HBITMAP hbm = CreateCompatibleBitmap(hdc, nTextBmpWidth,
nTextBmpHeight);
ReleaseDC(hwndApp, hdc);
// Select our bitmap into the device context and save the old one
BITMAP bm;
HBITMAP hbmOld;
GetObject(hbm, sizeof(bm), &bm);
hbmOld = (HBITMAP)SelectObject(hdcBmp, hbm);
...
I make a reference to this method in another class like this:
Code:
hr = Text.BlendText(___________, Text.g_szAppText);<- I need to know what to put in here
Does anybody know which method do i need to use in order to get this handle to the window i'm working with? I wonder if the question is clear, but i'll try!! Many thanks. Serj.

Did you try
AfxGetMainWnd()->m_hWnd

In continuation with Mr John... , you can use this tooo
AfxGetMainWnd()->GetSafeHwnd

I am trying to get the text from a control in another process. I know the handle for the control and I know the afx class name. It is as follows:
Class Name : Afx:400000:20
This control is part of a chatbox in an external application. I have tried several different things but I have so far failed to get the text from it.
Any ideas or help would be greatly appreciated.
Thanks.
Dave

I have tried sending the messages EM_GETLINECOUNT and WM_GETTEXT. Both return zero. This is a multiline text box. I have tried treating it as a CListBox, a CComboBox and a CListCtrl. All to no avail.

It's no surprise! Why haven't you tried CEdit instead? That, however, is not the problem here. If neither EM_GETLINECOUNT nor WM_GETTEXT worked, using an MFC class is just added complexity.

Send the WM_GETTEXT message to that control.

Check out this article, it has code that does what you want.http://www.codeproject.com/tools/WindowScraper_Utility.asp[^]
If you tried sending a WM_SETTEXT message to the window and it doesn't work, it could because the authors of the control did not implement a WM_SETTEXT handler. I see this error quite often in custom controls. What a lot of people seem to do is override the GetWindowText() function, instead of adding a WM_GETTEXT message handler.

how to change colour of static text at runtime.
|
|
|
|
|
Try using SetTextColor function of CDC by trapping the ON_WM_CTLCOLOR() message. In the message-handler OnCtlColor, use code like this:
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if(m_stText.m_hWnd == pWnd->m_hWnd)
{
pDC->SetTextColor(RGB(0,0,155));
}
return hbr;
}

hi,
thanks man it worked ,and for clearing the concept with that informative code
I added the following code to get the CWnd* handle to the static control from the IDC_
CWnd *m_stText=GetDlgItem(IDC_STATIC);and i guess it doesnt work with the button.

For Coloring the Button you either have to subclass it or make it owner drawn...

The WM_CTLCOLORSTATIC message is sent to the parent during drawing of the control. The HDC and HWND are provided to change the foreground colors. The return value is a brush to set the background.

Hello..
I'm trying to read in data coming from the serial port.. the data can come in at any time (so the program has to monitor the serial port continuously, thats why i'm using a while loop in my code below). I'm reading Tag IDs (strings) which are formatted into packets.. each packet starts with the '&' character and ends with the '$' character..
Right now I read in the whats coming from the serial port (using a infinite while loop) into a string and then tokenize that string according to my packet delimiters.. the problem is that Readfile is returning after getting part of the tag ID packet and then the remaining part of the tag ID packet comes the next time the while loop is called.. I think its something to do with the way I use the readfile function in the while loop..my code is given below.. Please advice..
Thank you for your help..
<br />
<br />
char buffer[200000];<br />
<br />
while (true)<br />
{<br />
printf("In while\n"); <br />
<br />
memset(buffer, 0, sizeof(buffer));<br />
if (ReadFile(h, buffer, sizeof(buffer)-1, &bytesRead, 0))<br />
{<br />
printf("Read file has a result\n"); <br />
if (bytesRead != 0)<br />
{<br />
printf("Got some bytes\n"); <br />
printf ("%s", buffer);<br />
<br />
printf( "Tokens in buffer:\n" );<br />
<br />
token = strtok(buffer, "&$" );<br />
<br />
while( token != NULL )<br />
{<br />
<br />
printf( " %s\n", token );<br />
<br />
token = strtok( NULL, "&$" );<br />
}<br />
<br />
}<br />
<br />
else <br />
{<br />
printf("No bytes read\n"); <br />
}<br />
}<br />
<br />
else {<br />
printf("Readfile didnt give proper result \n"); <br />
}<br />
Sleep(200);<br />
}<br />
<br />
