Is it possible to delete a pair without renaming the following keys?
I just tried, and the result is that VC will truncate the list at the first
empty place, that is, if you delete item3, (File3 key), the start page will only
show the first two items.

This is really bugging me... I can remember coming across an API several months ago that is like MessageBox() but it also puts a "don't show me this again" checkbox in the dialog, and automagically maintains a registry entry that holds the checkbox state. Now that I want to use this function, I can't find it. I thought it was a SHXxx or ShellXxx one (maybe one of the settlement APIs) but I've had no luck. Anyone know what I'm talking about here?

Are you sure? Memory can be a tricky thing.

If you are correct that there is a windows API that does this be sure to let us know what it is when you find it.

I would like to know as well, because, like PJ, I am pretty sure there is NOT one available.

Hello everyone.
I use the grid control(DBGrid) in my program and link it to a remote data control(RDC), through which a data source is connected to my program.
I have read two examples on the RDC downloaded from the networks. And I do not understand the useage of the member function SetCursorDriver().
If you can help me please reply my message, thank you.

We are working on web-narrator(reader) for hindi in that
we have prepared internet browser using Chtmlview class in mfc on which we are having button "PLAY" . problem is when i press it application starts playing the text(using TTS) but overall control of browser do not remains active it hangs up . i thing it is because of following code in play function spetially the loop of status checking
void CDirectSound::Play(DWORD dwStartPosition, BOOL bLoop)
{
if( ! IsValid() || ! IsEnabled() )
return; // no chance to play the sound ...
if( dwStartPosition > m_dwTheSound )
dwStartPosition = m_dwTheSound;
m_pDsb->SetCurrentPosition(dwStartPosition);
/*m_pDsb is member of CDirectSoundBuffer*/
if( DSERR_BUFFERLOST == m_pDsb->Play(0, 0, bLoop ? DSBPLAY_LOOPING : 0) ) {
// another application had stolen our buffer
// Note that a "Restore()" is not enough, because
// the sound data is invalid after Restore().
SetSoundData(m_pTheSound, m_dwTheSound);
// Try playing again
m_pDsb->Play(0, 0, bLoop ? DSBPLAY_LOOPING : 0);
//m_pDsb->GetStatus
}
LPDWORD lpdwStatus;
unsigned long ulStatus;
lpdwStatus=&ulStatus;
m_pDsb->GetStatus(lpdwStatus);
while(ulStatus!=0)
{
m_pDsb->GetStatus(lpdwStatus);
}
}
please if you get solution for the above problem do reply soon

Are you sure that 0 is the value you're looking for to terminate the loop? It could be that your logic is flawed. Checking the DirectSound documentation, IDirectSoundBuffer::GetStatus returns a combination of one or more of the following values:
DSBSTATUS_BUFFERLOST - The buffer is lost and must be restored before it can
be played or locked.
DSBSTATUS_LOOPING - The buffer is being looped. If this value is not set, the
buffer will stop when it reaches the end of the sound data. This value is
returned only in combination with DSBSTATUS_PLAYING.
DSBSTATUS_PLAYING - The buffer is playing. If this value is not set, the
buffer is stopped.
DSBSTATUS_LOCSOFTWARE - The buffer is playing in software. Set only for
buffers created with the DSBCAPS_LOCDEFER flag.
DSBSTATUS_LOCHARDWARE - The buffer is playing in hardware. Set only for
buffers created with the DSBCAPS_LOCDEFER flag.
DSBSTATUS_TERMINATED - The buffer was prematurely terminated by the voice
manager and is not playing. Set only for buffers created with the
DSBCAPS_LOCDEFER flag.
I'm not sure what values your own version of GetStatus returns,
but you may want to check for errors that may have terminated the playback. If some error occurs, can your own GetStatus *ever* return 0?
Just firing off some ideas...

I have an equation (abs(.223 - .323) / .223) *100 that isn't working - as I've researched the abs function it appears to only accept integer values? How do I get it to accept double or float values?
Thanks!

Visual Calc returns 44.843049 to (abs(0.223 - 0.323) / 0.223) * 100...
fabs() may be what you need...

How can VC++ implement the function of MATLAB function imread()?
That is, read in a jpg file, then get the pixel values.
Does any one know if there is any library for doing this?
Thanks

I use load frame to create a childFrame.
CChildFrame* ChildFrame=new CChildFrame(); <br />
ChildFrame->LoadFrame(IDD_COMMANDFORMVIEW,WS_OVERLAPPEDWINDOW|32768,AfxGetMainWnd());
The childframe is creating a FormView that has one editctrl.
The view is loaded and i can see but when i try to do a Ctrl-C or Ctrl-V in the edit box nothing happens! If i right-click and select 'paste' it works fine. What's wrong with it?
Is there any sample on the internet that makes use of LoadFrame where i can see what i'm doing wrong?

I found out that this is a general problem with Edit ctrls inside CFormView. You have to add an ON_UPDATE_HANDLER for ID_COPY,ID_PASTE, etc (that's why i couldn't find any WM_COPY, MFC turn them into commands!).

I have a problem with a simple ifstream in Visual C++ 6.0 (Console App). The following part of programcode produces a "0xC0000005: Access Violation" Error. Can anybody see the problem?
included headers:
#include "stdafx.h"
#include "conio.h"
#include "windows.h"
#include "iostream.h"
#include "fstream.h"
Code:
...
ifstream dat;
dat.open("c:\\back.ini");
if(!dat){
return false;
}
...
|
|
|
|
|
you may not test directly !dat. you should look the error bits of ios_base class...

No, the problem is to open the file. If i remove if(!dat), the same error occures.

|

but wher does it crash ?
could you please help us in copying the lines of code && error description ?

It crashes during the running process, its not during the compiling process. The Application end with the Errorcode:
Nicht abgefangene Ausnahme in back.exe: 0xC0000005: Access Violation.
and display's me a part from the istream.cpp:
istream& istream::operator>>(char * s)
{
int c;
unsigned int i, lim;
if (ipfx(0))
{
lim = (unsigned)(x_width-1);
x_width = 0;
if (!s)
{
state |= ios::failbit;
}
else
{
for (i=0; i< lim; i++)
{
c=bp->sgetc();
if (c==EOF)
{
state |= ios::eofbit;
if (!i)
state |= ios::failbit|ios::badbit;
break;
}
else if (isspace(c))
{
break;
}
else
{
Stopps here-> s[i] = (char)c; <---Application Stopps here
bp->stossc(); // advance pointer
}
}
if (!i)
state |= ios::failbit;
else
s[i] = '\0';
}
isfx();
}
return *this;
}
