Hi
My rich edit displays the text I streamed in
Somewhere in the middle of the text
I have tried various methods e.g. GetCurrentLine
LineIndex with a value of -1 to get the current line
Index to use in LineScroll to scroll back to the top
Of the rich edit but each of these methods returns
0
Any help appreciated it

First call LineIndex(-1) and feed that result into LineFromChar().

I Get Zero returned from both functions as I was tracing the return value with the value in the EAX
register
theline = myedit->LineFromChar(myedit->LineIndex(-1));

Does the control have multiline text in it? What line is the caret on?

Which may be the problem? I just created a test project, added a rich edit control with the WS_VSCROLL, WS_HSCROLL, and ES_MULTILINE styles, and the caret was visible and moveable.

Hi
I added to ES_AUTOHSCROLL and VSCROLL
The Caret seems to appear in the middle of the text but no scrolling here is a snipet of my code
<pre lang= 'cpp'>
in CProgDebug::ONINITDIALOG
long start, end, theline;
myedit = new CProgedit; // allocate the richedit
UpdateData(FALSE); // connect to dilog object
// myedit->SetOptions(ECOOP_OR, ECO_AUTOVSCROLL | ECO_AUTOHSCROLL);
EDITSTREAM es;
// Set the ENM_REQUESTRESIZE event flag
// myedit->SetEventMask( ENM_REQUESTRESIZE ); // set notificate to keep number of charcters in view
// Force the control to issue a EN_REQUESTRESIZE notification
// myedit->RequestResize( );
CStdioFile *fileptr = new CStdioFile;
fileptr->Open(proglisting,CFile::typeBinary);
es.dwCookie = (DWORD) fileptr;
es.dwError = 0;
es.pfnCallback = (EDITSTREAMCALLBACK) readlisting;
myedit->StreamIn(SF_TEXT, es);
myedit->SetFocus();
theline = myedit->LineFromChar(myedit->LineIndex(-1));
myedit->LineScroll(-theline,0);
myedit->HideSelection(TRUE,FALSE);
ShowWindow(SW_SHOW);
CDialog::OnInitDialog();
return TRUE;
}

I am trying to figure out how to create a emulator that loads multiple generic hid mouse devices in c (or generic mouse devices). Generic drivers are ones that are included with windows already. Anyone know where I should start or if this would be a hard task?
The end result is to make a c driver that emulates mouse input like the sendinput api except with multiple mouse devices.
The programs I was trying to get this to work in are: programs created with Microsoft multipoint sdk and Microsoft mouse mischief.
So far I do not have a c driver but have the technical details of the device on my project page (I want to get rid of dsf since its not 64-bit compatible): http://kinectmultipoint.codeplex.com. The emulator on the project does work now but I want to try and code a better system in.

Hello Every one,
I am adding some key in Registry is not getting into effect until system reboot or by killing explorer.
so how can i achieve it, without rebooting and killing explorer.
please help me out ..
Regards
sarfaraz

You shouldn't need to reboot unless registry key was in HKLM rather than user's own HKU hive.
Just log out and back in again. What was the reg key?
|
|
|
|
|
What process is it that needs to read the newly added key?

I want to ask you something: why CBitmap::CreateCompatibleBitmap() fail on large bitmap files ? I have:
VERIFY(m_Bitmap.CreateCompatibleBitmap(pDC, nWidth, nHeight));
and on large bitmaps, on debug, I get assert error ... why ?
|
|
|
|
|
Call GetLastError() upon failure to know more about the reason.
|
|
|
|
|
Thank you, I had tried to see what GetLastError get me, but get me nothing, I mean 0 ... always 0 ...
|
|
|
|
|
There are situations that GetLastError() returns 0 when the call fails (from MSDN and looking at the source of the MFC function):
- When a bitmap handle is already attached to the
CBitmap (asserts also); - When using Windows 9x (last error is never set, size is limited to 16 MB);
- When this can happen without being documented in the MSDN.
I hope this information helps you to find the reason.

Hello Everybody,
I am trying to pass some values to char ** (to a third party library). But i am getting some issue in that.
char** ids = new char*[m_Size];
for(int i=0; i<m_Size; i++)
{
ids[i] = mSizes[i].GetBuffer(mSizes[i].GetLength()); }
using that third party function, its creating an output file and in that file the stored value is showing like this.
GROUP : 46,0
GROUP : 44,0
GROUP : 42,0
GROUP : ÝÝÝÝÝÝÝ݆«ãe,0
GROUP : 40,0
GROUP : 38,0
But if I give values like this, then in output file, the values are showing fine.
char* ids[6] = {"38", "40", "42", "44", "46", "48"};
in the output file,
GROUP : 38,0
GROUP : 40,0
GROUP : 42,0
GROUP : 44,0
GROUP : 46,0
GROUP : 48,0
(see the sequence also)
what i am doing wrong? initialization ? or passing values ?
Thanks,
A. Gopinath.

The code looks fine. Because only one of the strings from your array returns wrong data, this element may be corrupted somewhere else.
Note also that you must call ReleaseBuffer() for each string array element after calling the library function. If not doing so, further accesses may return invalid data.
You should also check the documentation of the library if the passed strings are constant or may be changed. If they may be changed, you must pass the max. allowed length to GetBuffer().

char** ids = new char*[m_Size];
Here you create an array of char pointers.
Here:
ids[i] =
you need to create an aray of chars, so it should be ids[i] = new char [<some number="">]
Then copy the data into the char array.
==============================
Nothing to say.

In the first case, the pointers are pointing to memory maintained by the CStringArray class.
It is likely that CStringArray relocated, resized or moved the memory around.
So you need to allocate memory for each pointer and copy the contents to the allocated memory.
In the second case you have pointers to fixed locations that do not change.

I am aurpsised it even runs with out crashing since he is setting his array pointers to the values contained in some string!
So if the string was 'this monkley is stupid' the first pointer will have the value of the ASCII codes for 'this', the second pointer ' mon' and so on.
Of course these addresses are completely invalid and point to somewhere in his process. If he manipulated them in any way its bye bye process time!
==============================
Nothing to say.

Show some more of the actual code; there may be something wrong with it.
Use the best guess
