Thank you for your suggestion.
It got me thinking about the dialog style. In the main exe where I have a number of modeless dialogs, I set the dialog style to include control. This has the effect in the main exe of allowing the tab key to move between the controls on any modeless dialog. When the last control is exited (loses focus), the dialog style causes the tab key to move out of the current modeless dialog and enter the next modeless dialog.
But in the case of the DLL, this was not correct. The solution turned out to be to clear the dialog style settings and leave only the Visible checked.
Once I solved this small hitch (like two days later), I then discovered that while the tab key works properly inside the modeless Dialog created by the DLL, the effect of leaving the DLL was disabled. This was because the control style was not set.
In the end, I settled for raising an event (i.e. callback) on one of the controls in the DLL that changed the focus to a control in the main app.
in the following example, MyModeless was the hWnd returned from the DLL for the dialog
BOOL CMainEXEApp::PreTranslateMessage(MSG* pMsg)
{
if (TheView->MyModeless!=NULL)
{
if (IsDialogMessage(TheView->MyModeless, pMsg))
return TRUE;
}
return CWinApp::PreTranslateMessage(pMsg);
}
void CMainEXEApp::ChangeTabOrder( void * pPointer)
{
if (pPointer ==NULL)
{
SetFocus(TheView->GetDlgItem(IDC_BUTTON2)->m_hWnd);
}
}
Thanks for the response

Hi,
I would like to lead execution of my program with keyboard. I need function which will wait for keyboard input and would not spent any processor time.
Is it possible to use GetMessage() and message queues (window based aplications) in console application?

Hi,
try CString class ( you choose console->With MFC support).
With Regards,

This is one way...
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
int main(int argc, char* argv[])
{
// Initialise array
string source[] = {"i", "like", "to", "dance", "danci"};
// Sort it
int count = sizeof(source) / sizeof(source[0]);
sort(source, source + count);
// Print it
copy(source, source + count, // source
ostream_iterator<string>(cout, "\n")); // destination
cout << endl;
return 0;
}

This will also work if you replace "string" with "char*".

You can always make your own:
int __cdecl strcmp( const char * src, const char * dst )
{
int ret = 0 ;
while (! (ret = *(unsigned char *) src - *(unsigned char *) dst) && *dst)
++src, ++dst;
if (ret < 0)
ret = -1 ;
else if (ret > 0)
ret = 1 ;
return (ret);
}

Hi,
I am trying to reposition glyphs through Uniscribe. http://www.codeguru.com/forum/showthread.php?s=&threadid=284771 shows a diagram of what I am trying to achieve. The reason is also explained below.
Uniscribe’s ScriptTextOut function has a GOFFSET Structure (.du and .dv), apparently an ‘x,y Glyph offset’. In testing on both TrueType and OpenType fonts (Arial, Microsoft Sans Serif) this does not appear to modify the glyph position.
Q. Does anyone know how the GOFFSET feature works and whether it can offset vowel symbols?
There appears to be another helper technology associated with Uniscribe, Microsoft’s OpenType Layout Services (OTLS) which allows Glyph repositioning and substitution through access to the font’s GPOS and GSUB tables. However, the link http://www.microsoft.com/typography/developers/otls/ to OpenType Layout Service Library and Contact details no longer appear supported.
Q. Does anyone know how to obtain the OpenType Layout Service Library (OTLS)?
Q. Any other suggestions?
Why reposition glyphs?
I am trying to build a prototype for learning to read Arabic with the vowel symbols.
Arabic is difficult to learn to read. It is written from right-to-left and the letters can take as many as four forms. In addition, unlike European languages, beginners learning Arabic have to master reading letters and their accent symbol, representing vowels, stacked vertically two or three high. This combination of the letter and the associated vowel effectively form one syllable.
When Arabic text is displayed in Windows, the vowel and similar symbols are positioned to the end of the letter and not at identical heights. To make reading easier, I am trying to reposition these vowel symbols (glyph repositioning) so that these vowel symbols occur above or below the centre of the letter and at an equal height as illustrated in the example.

i use DirectX to get Video interface (Front surface) memory, size is 800x600x2 bytes.
when i try to get data from the memory, operating process is so slow (i.e. memcpy() function is 250 ms).
any one can give me some light in DirectX field to make it go faster?

Is there a possibility to change fonts in MessageBox(...)
Please help

No use chaning the font of the messagebox , coz we have litter control over it and other complication may come into the picture, Instead go for custom messagebox, i think it goes by the name XMessageBox here in codeproject.

as i understood critical is used to control the access of different threads over a resource.
I performed the following experiment.
defined a critical section structure.
initialiaed the critical section
I then in a functino called
Entercriticalsection(...); followed by again
Entercriticalsection(...);
I thought it should threadlock in the second call, but its not locking the thread. am i missing something ?

The critical section is already owned by the calling thread so the second call will slip trough.
Try it from two different threads instead.
And you must have a matching LeaveCritcalSection() call for each EnterCritcalSection().

Friends, i hope that you are all aware of MSN messenger. There is an Edit Box in this application where we can type our nick. In this edit box we can also display Unicode characters.
So i just launched my Visual C++ 7.0 IDE and developed a dialog based application. I changed the settings from MBCS to UNICODE. Then i dropped a simple text box on it. Then i run the program.
But as such the text box is not accepting the Unicode characters. When i pasted the unicode characters on this dialog box, something like "??????" appeared.
Can anyone tell me how can i display unicode in edit box ?
|

|
|

They are called multilingual char not unicode char, unicode char supports multilingual chars. It depends on the language settings of ur machine to see the correct text.

Friends,
I've a simple dialog based application. I dropped a Rich Edit control on a dialog. I run the program and it runs fine. As such the font typed in the rich edit box is the one provided by Windows as default font.
Now i want to display the text in rich edit box with my custom fonts settings. I got a routine to do so. And i want my font settings to be applied as default when the application runs. So i am calling my function of font change in OnInitDialog().
OnInitDialog()
{
m_myRichEdit.SetFont("Tahoma");
m_myrichEdit.SetFontSize(22);
}
But when i run my application, these settings are not getting applied  Instead if i remove the code from OnInitDialog() and place it in OnOk() handler then it gets applied if the user presses the OK button.
But i want my settings to be applied immediately when the application runs i.e applied as default.
How can i do so ???
The routines are:
void CRichEditCtrlEx::SetFontName(CString sFontName)
{
CHARFORMAT cf = GetCharFormat();
ZeroMemory(cf.szFaceName, 32);
for (int i = 0; i <= sFontName.GetLength()-1; i++)
cf.szFaceName[i] = sFontName[i];
ZeroMemory(cf.szFaceName+ sFontName.GetLength(), 2);
cf.dwMask = CFM_FACE;
SetSelectionCharFormat(cf);
}
void CRichEditCtrlEx::SetFontSize(int nPointSize)
{
CHARFORMAT cf = GetCharFormat();
nPointSize *= 20;
cf.yHeight = nPointSize;
cf.dwMask = CFM_SIZE;
SetDefaultCharFormat(cf);
}

I take some picture round the sence,how can i combine these picture into panoramic image by programming .

The best way to handle this is to give the user some intervention. Step-through each pair of images and display then side-by-side. Give the user an interface where they can click a point in picture #1 then click the corresponding overlap point in picture #2. Collect as many data points as you want to manipulate.
Then when you merge these two images, overlay those designated points, and weight the pixels surrounding those points so as to "stretch" or "shrink" those regions based on how close they are to the clicked points and how much stretching or shrinking you need to do. You can also adjust the transparency around those regions to blend the two images together. That usually helps with the transition.
Good luck. It's not as easy as just slapping 3 or 4 images next to one another.

Yup:
static const UINT SWM_TASKBAR_CREATED = RegisterWindowMessage(_T("TaskbarCreated"));
Listen for this message (in MFC, use the ON_REGISTERED_MESSAGE() macro in your message map), and re-add the icon when it is recieved.

HI Prakash!
In one of the message U told that U have an application which runs in Background. I also need some program[Win32] to run in Background and monitors system activity. In exact word I should be able to know, when say user has started some exe (ex.Yahoo messenger executable). Right now I am using application which uses EnumProcess API to obtain the handle of all running process.
It should work for Win98 as well as for WinNT. Hence I think writing service is not a good idea.Any Suggestion.
And my god U are turning out to be answering machine. Whole page is filled with U. Great going chap.
Cheers!!
