Hi, Thanks for your reply. Indeed I am using a 3rd party library but they are all set to ANSI (no unicode at all). I fixed the problem by dynamically changing the Dialog Title. Regards,

Hi, I have used older projects with Greek characters in ANSI and code pages without problems. Indeed unicode will solve the problem, but this specific project is too big and I have to make too many changes to finally make it work fine. Anyway, I managed to fix the problem changing the title of the title dynamically inside the code. Take in mind that when I recall strings from the Resource String Table using CString.LoadString(ID) I get gibberish but when I am using CStringW.LoadString(ID) it works. My String Table is not Unicode but inside VS2008 I set it up as Greek code page.

Hi, Thank you for your interest... Its the 1st time I meet this kind of problem. My Visual Studio is pretty old v2008 and the project settings are similar. Both Debug and Release share the same *.rc file. They are both an MFC Static, not using ATL and Character Set are "not set". My nonlatin character set is Greek. I can see the Greek titles in my dialog boxes in the editor. The only problem here is the Release version of the app. Don't know where to look for a problem. Regards,

Hi, I am using an MFC dialog (ANSI no Unicode) created in the resource editor with a nonlatin character name in its title, as a Property page. While running the debug mode I can see the nonlatin title in release mode I get a gibberish characters. What seems to be wrong here?

Thanks for your answer. The CGdiPlusBitmapResource is part of an older codeproject.com article at Loading JPG & PNG resources using GDI+[^] Anyway, I found the root of the problem. I had to call DrawImage with the size of the image. Now all works just fine.

graphics.DrawImage(*pPngChannel, 0, 0, 800, 50);

Using the code below (called from void CLoadPngDlg::OnPaint()) I am trying to view a PNG file that already included in the resource (IDB_FULLSCRINFOBAR_OPAQ_TEST). As you can see in the image attached the bottom red line and the rightmost column of pixels are not shown. https://i.imgur.com/Ug6gYjr.jpg Image Attached[^] What seems to be the problem here?

BOOL CLoadPngDlg::ShowPngAt(CDC *dcWnd) {

CGdiPlusBitmapResource		\*pPngChannel;
UINT						nWidth,nHeight;
CRect						rectClient;
CBitmap						Bitmap, \*pOldBitmap;	
CDC							bitmapDC;
CDC							\*dialogDC;

pPngChannel	= NULL;
pPngChannel = new CGdiPlusBitmapResource;

if (!pPngChannel->Load(IDB\_FULLSCRINFOBAR\_OPAQ\_TEST, \_T("PNG"))) {
	delete pPngChannel;
	return TRUE;
}

GetWindowRect(&rectClient);

// Get size of bitmap.
nWidth = pPngChannel->m\_pBitmap->GetWidth();
nHeight = pPngChannel->m\_pBitmap->GetHeight();

bitmapDC.CreateCompatibleDC( dcWnd ); 
Bitmap.CreateCompatibleBitmap(dcWnd, nWidth, nHeight);
pOldBitmap = bitmapDC.SelectObject(&Bitmap);	

Gdiplus::Graphics graphics(bitmapDC.GetSafeHdc());										
graphics.DrawImage(\*pPngChannel, 0, 0);

dcWnd->BitBlt(0, 0, rectClient.Width(), rectClient.Height(), &bitmapDC,   0,  0,   SRCCOPY );

bitmapDC.SelectObject( pOldBitmap );
bitmapDC.DeleteDC();


if (pPngChannel != NULL)
	delete pPngChannel;


return FALSE;

Hi, I want to send raw esc/pos (epson compatible) text data (not graphics) to a cheap chinese POS58 thermal printer using either MFC or Console32 application. Is there any library or sample to start of ? Regards,

According to this microsoft's article [^], if I wanted to use ShellExecute to open the default browser instead of the Internet Explorer, I had to use

LONG r = ShellExecute(NULL, "open", "http://www.microsoft.com", NULL, NULL, SW_SHOWNORMAL);

Ok. In my case I want to open this url http://www.mywebsite.com/article/month/section. I am doing this :

AfxParseURL((LPCTSTR)m_strWebURL, dwServiceType, strServerName, strObject,nPort);
strServerName = _T("http://") + strServerName;
::ShellExecute(NULL,_T("open"),strServerName,strObject ,NULL,SW_SHOWMAXIMIZED);

This piece of code crashes the Visual Studio 2008. The original code i used below is worked just fine but it uses Internet Explorer instead of the default browser.

::ShellExecute(NULL,_T("open"),_T("explorer"),m_strWebURL ,NULL,SW_SHOWMAXIMIZED);

What seems to be the problem in microsoft's code ? Regards,

sdancer75

Thank you for your help :-) Best Regards,

Thank you Is that backward compatible with windows xp/vista ? I think that win Xp does not support AppData. Is that correct ? What to do in this case ? Check the os and take a path decision specifically for it ?

Windows 7 UAC prevents my application to write log data in the installation folder. The original text log file exists from the very beggining, but its empty. When I start my app with the -L parameter to start logging, it does not write anything due the UAC control. If I rum my app with Admin Priviledges then it works. As you can understand I can not suggest my client to run the app with right click and "run as an Administrator". Is there any solution for that ? Best Regards,

Finally I used MsgWaitForMultipleObjects with message process loop. I avoid to use EnableWindow() function at all. It seems to work fine under Win7. I will take a copy to my work tommorow to test it under XP for paint corruption.

You can disable your app window and/or show a modal dialog while the worker thread is active and re-enable when it finishes.

You mean a dummy dialog just to block to main app ?

Quote:

What do you mean by floating windows? There is no additional window.

I mean the two windows that will be active at the same time (main and child) and user will have the ability to work with the both of them.

sdancer75

One last thing. The EnableWindow(xxxx) do the mess in my situation. If I dont use this function I have to process the paint messages from the child window. In this case I think that

WaitForMultipleObjects

will do the job in the XP case. Do you agree with this guess ? .... or better i will give it a try right now.

sdancer75

The worker thread does not lock the main app as long as its active. I dont want this. I just want a modal like behaviour and not floating windows all around the desktop.

sdancer75

Seems to work with one exception. I get a flicker since it instantly lose its focus and then regain it back....

sdancer75

Thanks for your time. Do you suggest to use WaitForMultipleObjects instead ?

sdancer75

I will give it a try but as you may already see, I am using the bringWindowToTop without success. Thanx

Hi, No problem at all, I just gave all the code in the link. Anyway, I attach you the most important code from the sample app.

void CMainFrame::OnRunExternalApp() {

SHELLEXECUTEINFO	lpExecInfo;
PROCESS\_INFORMATION processInfo;
DWORD				dwExitCode;
HANDLE				hProcess = 0;
BOOL				bResult;
LPTSTR				strCmd;





strCmd = \_T("");

//bResult = StartupApplicationWithShell (\_T("LiveUpdate.exe"), (LPTSTR)strCmd,  GetSafeHwnd(), &hProcess);
bResult = StartupApplicationWithProcess (\_T("C:\\\\Windows\\\\notepad.exe"), (LPTSTR)strCmd,  &processInfo);

EnableWindow(FALSE);



if(bResult) { //(UINT)result > HINSTANCE\_ERROR)

	//ShowWindow( SW\_HIDE );
	//ShowWindow( SW\_SHOWNOACTIVATE );
	

    //WaitForSingleObject( hProcess, INFINITE );
	WaitForSingleObject(processInfo.hProcess, INFINITE);
	//WaitForMultipleObjects(1, &processInfo.hThread, TRUE, INFINITE );



	   
	//if (!GetExitCodeProcess(hProcess, &dwExitCode)) {
	//	   	AMLOGINFO(\_T("LiveUpdate is not terminated normally.")); 
	//}
	if (!GetExitCodeProcess(processInfo.hProcess, &dwExitCode)) {
		   	//failed
	}
	CloseHandle( processInfo.hProcess );
    CloseHandle( processInfo.hThread );
	//CloseHandle(hProcess);


} else {
	
	// failed
}

BringWindowToTop();
EnableWindow(TRUE);

//UpdateWindow();

//::SetWindowPos( GetSafeHwnd(), HWND\_TOP, 0, 0, 0, 0, SWP\_NOMOVE | SWP\_NOSIZE | SWP\_SHOWWINDOW );

}

I posted a link in my 1st post with a sample MFC/SDI application that have all the code you need. http://www.filedropper.com/shellexecutecreateprocesstestapp[^]
