Hi!
I have a problem with Autoscrolling in an CEdit. The Code i written works fine for scrolling but has an ugly graphic-error.
It scrolls the text in the direction where i have the mousecursor. If i scroll up the first visible line is shown 2 times.
When I scroll down it is the last visible line.
Here is the code:
// MyEdit.cpp: Implementierungsdatei
//
#include "stdafx.h"
#include "MyEdit.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
/////////////////////////////////////////////////////////////////////////////
// MyEdit
MyEdit::MyEdit()
{
iScrollCount = 0;
iScrollSpeed = 5;
}
MyEdit::~MyEdit()
{
}
BEGIN_MESSAGE_MAP(MyEdit, CEdit)
//{{AFX_MSG_MAP(MyEdit)
ON_WM_SETCURSOR()
ON_WM_NCHITTEST()
ON_WM_TIMER()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////
// Behandlungsroutinen für Nachrichten MyEdit
BOOL MyEdit::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
// TODO: Code für die Behandlungsroutine für Nachrichten hier einfügen und/oder Standard aufrufen
HCURSOR g_CursorIcon;
g_CursorIcon=LoadCursor (NULL,IDC_SIZENS);
SetCursor(g_CursorIcon);
//return CEdit::OnSetCursor(pWnd, nHitTest, message);
return 1;
}
UINT MyEdit::OnNcHitTest(CPoint point)
{
// TODO: Code für die Behandlungsroutine für Nachrichten hier einfügen und/oder Standard aufrufen
CRect rect;
GetClientRect( &rect );
ScreenToClient(&point);
if(point.y > (rect.bottom - 60))
{
KillTimer(0);
SetTimer(1,25,0);
}
else if(point.y < 60)
{
KillTimer(1);
SetTimer(0,25,0);
}
else
{
KillTimer(0);
KillTimer(1);
}
return CEdit::OnNcHitTest(point);
}
void MyEdit::SetScrollSpeed(int Speed)
{
iScrollSpeed = Speed;
}
void MyEdit::OnTimer(UINT nIDEvent)
{
// TODO: Code für die Behandlungsroutine für Nachrichten hier einfügen und/oder Standard aufrufen
CPoint point;
GetCursorPos(&point);
ScreenToClient(&point);
CRect rect;
GetClientRect( &rect );
if(point.y > rect.bottom || point.y < 0 || point.y < rect.bottom && point.x < rect.left ||point.y < rect.bottom && point.x > rect.right )
{
}
else
{
if(nIDEvent == 1)
{
if(iScrollCount == iScrollSpeed)
{
LineScroll(1,0);
iScrollCount = 0;
}
else
iScrollCount++;
}
else
{
if(iScrollCount == iScrollSpeed)
{
LineScroll(-1,0);
iScrollCount = 0;
}
else
iScrollCount++;
}
}
CEdit::OnTimer(nIDEvent);
}

Hi,
I have to programs, both written in MDI, MFC,
I am able to call the executable of program2 from program1, by using CreateProcess method.
My question is, How can I call the methods of program2, within program1.
or how can I have a pointer to the View class of program2 from program1.
Thanks

They are two processes in different address spaces. You cannot access objeects between address spaces. One solution to sharing data is file-mapping. Another solution is pipe. Another solution is WM_COPYDATA.

1) You can use Automatization. You must create type library from View class of program2, and after calling CreateProcess in program1, attach to running Program2's instance. You can provide values, with which you would be able to change variable values in program2, from program1, execute some code in program2(methods), etc. program2 will be server of Automatization and program1 will be client n this case.

Check CodeProject for a good progress bar class.
As for updating text in the status bar, one solution is SetPaneText().

I have an edit box. I click properties and removed the border.
When some types something in that edit box, the text starts in
the upper left corner. How can I remove the border, but make
the text start down 1 or 2 pixels and to the right more by
1 or 2 pixels? I like not having a border, but I want the
text to appear vertically centered in the edit box and just
start off the edge.
Please any response any one can give me will be greatly
appreciated.
Sincerely,
Danielle (an overworked graduate student)

Hi all
In my MFC dailog i used my itself ActiveX controls.But when its dialog recieved WM_PAINT message it not redraw my controls to the end.Sometimes controls drawing on half or less sometimes almost complete.Whats a problem here???
There are more explicity referience of this trouble
I have 2 thread
First thread its a console application which create second thread .This first thread not call _beginthread function
instead of one use CoInitializeEx() function and create new appartment.In this new appartment created COM object what launch MFC dialog box with 2 controls. Behaviour of this control fine while i dont sinchronized this two thread.
Sinchronizing i implemented this way:
COM object from the secon thread have method IsLock its method returned true while in dialog not pressed any key.
In first thread i maked loop what check this method and continued execution of first thread as soon as IsLock method
became false i.e.
First thread
...
while(cptr->isLock){} //Blocked its thread while isLock true
...
Second thread
CMyObj::get_isLock(VARIANT_BOOL* pVal){
*pVal = lock_fg;
}
...
CMyDlg::OnKey(){
lock_fg = false;
}
...
and after this i see whats my dialog are drawing not properly.
Sorry for complicated explonation and my eanglish.
Thanks.

I try to load icmp.dll and call three functions from it (by address): IcmpCreateFile, IcmpSendEcho, IcmpCloseHandle.
On WinXP it works without any errors, I recieve right functions' addresses, call this functions without problems, etc.
On Win2000 i recieve correct handle of loaded icmp.dll but:
1) When I call GetProcAddress() for any of this three functions at first time, I recieve positive(!=NULL) value, but when I call function by this address, I recieve following message: ".., Memory could not by written,...".
2) When I call GetProcAddress() for last two functions, I recieve NULL.

Sounds like a different version of the dll. I'd double check to make sure. Other than that, I can't say what's wrong.

Hi,
I would like to know if it's possible to change the title name of a AfxMessageBox or a MessageBox?
thanks
Mykel
Everything's beautiful if you look at it long enough...
|
|
|
|
|
Simplest way is to use ::MessageBox
Arjan.
|
|
|
|
|
Use MessageBox instead of AfxMessageBox:
MessageBox(AfxGetMainWnd(),"Text","Title",MB_OK);
or
MessageBox("Text","Title");
depending in wich class you're using it.
Hope this helps
|
|
|
|

AfxMessageBox() will use 'm_pszAppName' as the title name. The best way is to use MessageBox(). If you want to use resource as input message, here's an example:
int MyMessageBox(UINT nIDPrompt,LPCTSTR lpszTitle, UINT nType)
{
HMODULE hThisApp;
DWORD dwLen,dwBufSize;
int nResult;
hThisApp=AfxGetInstanceHandle();
_TCHAR *lpszText=NULL;
dwBufSize=0;
do
{
delete [] lpszText;
dwBufSize+=256;
lpszText=new _TCHAR[dwBufSize];
dwLen=LoadString(hThisApp,nIDPrompt,lpszText,dwBufSize);
} while((0!=dwLen)&&(dwLen+sizeof(_TCHAR)==dwBufSize));
nResult=MessageBox(GetActiveWindow(),lpszText,lpszTitle,nType|MB_TASKMODAL);
delete [] lpszText;
return nResult;
}
Best Regards,
K Wan

I can change the color of the progress bar indicator in Windows 2000 with:
m_myProgressCtrl.SendMessage(PBM_SETBARCOLOR, 0, color)
..but on Windows XP this does not work. Anyone knows why? ...and how to fix this?

Hey friend
Check the Internet explorer Version on that Machine.
I think there should be no problem as it is supported on 2000
but one imp thing there is nothing written about the XP OS so as far as i think should work
Thanx
TAKE CARE
|
|
|
|

Siid, thanx for your (quick) reply. I checked the explorer versions. My Win2000 system has ie 5.5 and my XP system has version 6.0. So I don't see why it would work on my 2000 system and not on my XP system...but I doesn't work anyway.

I'm still trying to figure out this whole printing thing. I've got a question that's probably been answered 100 times in this forum before...when I do a print preview, my file looks perfect on the screen until I move anything. If I use the scroll bar, or zoom in on the page, it just goes blank and nothing shows up again in the page. Any suggestions?
Thanks!

Hello,
I need some help with creating a word maker in Java. the user should be able to enter a list of words at least nine of them (3 x 3) grid will be formed and should be abl to grow.
an import button should be available to import a list of words from a text file into a world list which will be compared with the list of words in the grid.
a make grid button should be availabe to allow the user create the grid after the letters have been entered.
a make word button should also be available for the user to click and search for the words in the grid. the words can be found diagonally, horizontally and vertically.
if i could get some help on how to do this i'll be very greatful thanx.
