processInfo->szExeFile is a pointer. When you try comparing it or print it you are really testing the address. You should de-reference it first ie
if( *processInfo->szExeFile == _T("hello.exe"))
cout<<endl<<"Name: "<<*processInfo->szExeFile;

Hi I would like to make a program that ginen a wave file it filter (bandpass or low and Hi) and play the sample. It's possible? How?
I'm trying to: make FFT -> cut the frequency -> make a IFFT -> then play.
For FFT and IFFT for example I can use this code:
http://www.codeproject.com/cpp/howtofft.asp[^]
But the I load a wave the samples for second it's non a multiple of 2 and no FFT is possible. How can I do?

I think you add/remove some samples to the data set to make it a 2^n one. I don't remember the details though.
Best,
Jun

Yes, but how resample without distort the wave or without lose too much quality?

I get LNK2005 errors with the static CRuntimeClass datamember of the specialized template
Why?
I simplified the classes to highlight the problem.
TXBase contains special algorithms and also the CRuntimeClass functions and static classTXBase to make RUNTIME_CLASS things work.
////////////////////////////////////////////////////////////
// TXView template
////////////////////////////////////////////////////////////
#undef CLASS_NAME
#define CLASS_NAME classTXView_##BASE
template < class BASE >
class TXView : public TXBase < BASE >
{
public:
TXView(UINT nIDTemplate = 0);
virtual CRuntimeClass* GetRuntimeClass();
static const CRuntimeClass CLASS_NAME;
};
template < class BASE > TXView< BASE >::TXView(UINT nIDTemplate /*= 0*/)
: TXBase< BASE >::TXBase(nIDTemplate)
{
}
template < class BASE > const CRuntimeClass TXView<base />::CLASS_NAME =

Hello
I´m inserting a bitmap image in my dialog with a picture control, and i want it
to be transparent like when you insert an icon in a dialog, and you set the background
colour to some kind of green at visual studio icon editor and it do the trick.
So, what background color should I use with bitmaps?
btw I´m using Visual Studio 2003 IDE.
thank´s.

This is a little work:
http://www.codeproject.com/staticctrl/LayeredBitmapCtrl1.asp
or look yourself for "transparent"

There ia a GDI function called TransparentBlt(), but it is not very good. The best approach is to use two bitmaps. The first should be black in all areas you want transparent and white in all other areas. The secon, your picture, should be white in all areas you want transparent. You draw these two over the top of each other. The fist bitmap using BitBlt() with SRCAND, the second using BitBlt with SRCPAINT. The result is a transparent bitmap.

|

Actually, the easiest possible way of doing this is probably by just using an ImageList to draw your bitmap, specifying a mask color.

ok thanks all, i will try all the methods, and read the site as well..

Hi,
I am making a custom crash handler for application, and just thought about something.
I am using sprintf, strcat and strlen in handler, are they safe to use even after possible heap corruption?

That would depend on if they were operating on heap variables or not.

In general, after the heap has been corrupted all bets are off.

Hi, thanks for answers..
Went throught source code of those (sprintf, strcat, strcpy and strlen) and it seems sprintf is unsafe, since it uses malloc, but strcat,strcpy and strlen are so simple and straightforward and they don't use heap so they are probably? ok..
Well, have to replace sprintf with strcpy,strcat,strlen combination..

i intialised buttons with color and icon on that button in OnIntilaUpdate()
function.

Can u explain PLZ?

How you have done this?
I guess, you need to write that code in OnDraw, because OnIntilaUpdate get called once, and subsequent painting operation overrides, what you have done there.

I included one CButtonSt class from one of the samples in code project.
I tried it OnDraw but i got assertion failure....
|
|
|
|
|
Can you show some code, causing this to happen ?
|
|
|
|
|
<br />
void CFirstLook::OnInitialUpdate() <br />
{<br />
CFormView::OnInitialUpdate();<br />
<br />
<br />
<br />
<br />
m_btnApps.SetIcon(IDI_ICON2);<br />
<br />
m_btnApps.SetColor(2,RGB(128,128,128),FALSE);<br />
m_btnApps.SetColor(0,RGB(255,0,0),TRUE);<br />
<br />
<br />
}<br />
void CFirstLook::OnDraw(CDC* pDC) <br />
{<br />
<br />
<br />
<br />
<br />
}<br />
If i put it OnDraw i got assertion Failure.
I put it in Class contstructor i got assertion failure
but i ignore this i got the form window and after clicking on that button
am gettiong icon.

did you used from debugger?

You better post this to article, where you get this sample from.
As nobody know, how CButtonSt looks like.

hi all,
I have dynamically created a CEdit Control in the Dialog. When ever i Right Click in the EditBox i have to show popup a Menu. Then I select the FirstMenu Item from Menu must show a CColorDialog and choose a Color and store it in a COLORREF variable. This is done using TrackPopupMenu(...) when ever i Right Click in the Newly Created EditBox Dynamically.
after choosing the Color from the ColorDialog Box. That Color Must be Reflected in the Edit Box where ever i RightClicked.
//===========================================================================
void CExpDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
CClientDC *dc = new CClientDC(this);
ptr = new CEdit; //Create Dynamic Edit Control Here
ptr->Create(WS_VISIBLE|WS_CHILD|WS_BORDER|WS_TABSTOP|ES_AUTOHSCROLL,CRect (point.x,point.y,point.x +100, point.y +20),this,ctr++);// Dynamic Edit.
CDialog::OnLButtonDown(nFlags, point);
}
HBRUSH CExpDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
switch (nCtlColor)
{
case CTLCOLOR_EDIT: //For General EditBox. here i am bit confused
pDC->SetBkColor(c); // where c is COLORREf selected in ColorDialog
break;
}
return 0;
}
//This when ever i right Click on the newly Created EditBox Item.
void CExpDlg::OnParentNotify(UINT message, LPARAM lParam)
{
if(message == WM_RBUTTONDOWN)
{
CPoint pt(LOWORD(lParam),HIWORD(lParam));
PopupMenu (&pt);
}
}
//Populate the Menu Item
void CExpDlg::PopupMenu(CPoint* pt)
{
ClientToScreen (pt);
CMenu FloatingMenu;
FloatingMenu.LoadMenu(IDR_MENU1);
CMenu* pPopupMenu = FloatingMenu.GetSubMenu (0);
pPopupMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,pt->x, pt->y, this);
}
//This is the Menu Item when the TrackPopUp is Shown.
void CExpDlg::OnObjetsOne()
{
CColorDialog dlg;
if(dlg.DoModal()== IDOK)
{
c = dlg.GetColor(); // c is the ColorRef of the ColorDialog.
}
}
Here the New color what i am choosing is not Reflected to the EditBox which i Created Dynamically.
please provide me a solution.
