Hi all:
I have a pure white background imagelist which is used for the TabCtrl. But what the problem is when I add this icon to the TabCtrl, it seems it didn't mask the white back ground out. The following is the code
bitmap.LoadBitmap(IDB_ICON);<br />
imgList.Add(&bitmap, RGB(255, 255, 255));
tabctrl.SetImageList(&imgList);<br />
tabctrl.InsertItem(0, "", 0);
I've tried imglist.SetBKColor(CLR_NONE); the result is still the same!
Can anyone help me fix the problem?

i want to develop a client-server application where the client application is an executable. whenever the executable starts, it should first contact the server, get validated and only then start. the purpose behind it is to see that only those machines for which the server maintains a list can run the executable. can any1 suggest me some sample code or some suggestions on how to proceed?

Hi
Can Visual C++ .Net compiler genarate and make use of the SSE instructions of Intel processors (like Pentium 3 and Pentium 4)?
Let me say it in another way:
Can the compiler make use of the parallel-processing capability of the SSE extension on optimizing the genarated code of my program? Or I should myself use SSE instructios explicitly to make use of SSE capability?
Thank you and Sorry if I did not make it clear.

i think based on compilation flags like /arch:SSE, /arch:SSE2, compiler will generate the optimised code

Thanks naren.
I already checked the link provided by you and found no clear statement that .Net produce Parallel SSE code. Yes, the compiler can genarate and use SSE instructions but I ask whether it can use the parallel
capability of the SSE extension which I have no evidence it's could be done by the compiler!!!
thanks again naren

Code :
at .cpp file :
IMPLEMENT_DYNAMIC(alb2CaptureOptionTree , COptionTree)
//two .h file
class COptionTree : public CWnd
{
....................
}
class alb2CaptureOptionTree : public COptionTree
{
DECLARE_DYNAMIC(alb2CaptureOptionTree)
..........
}
Error :
when compiling the code , Errors occur .
error C2039: 'classCOptionTree' : is not a member of 'COptionTree'
error C2065: 'classCOptionTree' : undeclared identifier
In fact , I never define a class named classCOptionTree.
Why ?
What's the reason?
Thank you !

add DECLARE_DYNAMIC in base class also. In ur code add
DECLARE_DYNAMIC(COptionTree) in class COptionTree, and add
IMPLEMENT_DYNAMIC(COptionTree,CWnd)in the cpp file

try by setting the correct lib paths. Is it linking successfully if u omit the DECLARE_DYNAMIC, IMPLEMENT_DYNAMIC??

What lib paths do I need ? I don't know.
can you tell me ?

is it linking successfully without DECLARE_DYNAMIC, IMPLEMENT_DYNAMIC

check with the definition of IMPLEMENT_DYNAMIC. ultimately it will call the CRuntimeClass(base_class). Thats why u need to implement dynamic creattion inevery class in up heirarchy

Hello,
The DELCARE_SomeThing {SERIAL, DYNAMIC and DYNCREATE} macros are used to implement some features provided by CObject. Some of these features are RTTI provided by MFC, serialization and dynamic creation using the RUNTIME_CLASS macro.
If your class wants to use one or more of these features, it should be derived from a class that has these features. If you don't you'll get those errors you had. Read here[^] for more information about CObject and dynamic object support.

I made a basic dialog and it has a CEdit Box ( IDC_EDIT1 )
inside its implementation file.
CScrolling_CwndDlg.h
CPRPViewStaticMap m_prpviewstaticmap_inst;
CScrolling_CwndDlg.cpp
OnInitDialog(){
m_prpviewstaticmap_inst.SubclassDlgItem( IDC_EDIT1, this );
m_prpviewstaticmap_inst.ShowScrollBarSB_BOTH,TRUE);
}
The CPRPViewStaticMap is derived from CWnd
class CPRPViewStaticMap : public CWnd
inside the implementation file shown below
i tried to draw images
the problem is the images go out of the CEdit container
they also overlap the scroll bars instead of being under it.
void CPRPViewStaticMap::OnPaint() {
CBitmap BkBmp;
BkBmp.LoadBitmap(IDB_BITMAP1);
CDC BmpDc;
BmpDc.CreateCompatibleDC(pdc);
BmpDc.SelectObject(&BkBmp);
m_symbolx = 360;
for(int xr=0; xr<3; xr++){
m_symbolx = m_symbolx + 70;
pdc->BitBlt( m_symbolx,
90,
70,
70,
&BmpDc2,
0,
0,
SRCCOPY);
}
}
has anyone encountered this problem before?
how did you solve it?
Thank you very much

Constrain your BitBlt to not overwrite the area where the scroll bars are located or else set a clipping rectanlge prior to drawing the bitmap. Either way, you need to calculate the recangle it will FIT into, otherwise, it will just erase everything in its path.

Who know how to write a program to let a progress bar run until 100% using MFC C++
is this programming correct..
Progressdlg = new CProgress(this);
Progressdlg ->Create(this, CProgress::IDD);
Progressdlg ->ShowWindow(SW_SHOW);
step_number = 0.0;
step_number = 1; // number of percentage completed for each file
out of the total loaded
max_range = 100; // equivalent to 100%
percentage_increase = 1;
Trigger_Time[i] = Trigger; // Store the Trigger Timer for each slice
Progressdlg->m_ProgressBar.SetRange(0, max_range);
Progressdlg->m_ProgressBar.SetStep(step_number);
Progressdlg->m_ProgressBar.StepIt();
// Calculate percentage
progress = ((percentage_increase/32) * 100);
// Convert percentage from int to CString format to display in static text
control
progress_percent.Format("%d %%", progress);
total_file.Format("%d of %d percent", percentage_increase, (int)max_range);
Progressdlg->SetDlgItemText(IDC_TOTAL_FILE, total_file);
Progressdlg->SetDlgItemText(IDC_CURRENTLY, PCMRIfile[i]);
percentage_increase++;

You don't need to call StepIt, you can just set the position. I think that would be a more reliable way to go.

Damn - is that English ?
The SetPos[^] function lets you set the progress bar control as an absolute value.

sorry... i dun understand what u mean by You don't need to call StepIt, you can just set the position.can u show me how to do...

*sigh*
1. PLEASE try to speak English. u is not a word, neither is dun.
2. You don't need to call StepIt, because SetPos allows you to specify exactly the progress position. So when you work it out as a factor of 100, pass that value in to the SetPos method.

sorry to ask one more question.. what is SetPos method
