unfortunately, the displayed picture is only black
this doesn't work
Ohter Ideas?
I think the failure must be in the CBitmap. Its creation must be buggy.

I never used CBitmap::SetBitmapBits, so I can't tell if it works well.
what is your object pDC? A ClientDC?

pDC is the DC of the control(picture-control) into which i want to paint the bitmap
CDC *pDC = GetDlgItem(IDC...)->GetDC();
|
|
|
|
|
I've never use a picture control this way, and I don't know if it is possible to use directly its DC.
Why not using directly a CWnd and catch the WM_PAINT message? At least you would have a total control of the drawing.

The Problem is the creation of the cbitmap. If i load it from a file or from a ressource it works the way i like.
Only to create its own cbitmap makes some trouble

Have you tried to work with a BITMAP structure (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/bitmaps_2h6a.asp)? Once all the fields of the structure set, it's easy to convert it to a CBitmap object.

I currently have an array filled with int values from 0 to 255, but I need to pass this array into a function that takes double. So my problem is I can't convert the int array of values 0 to 255 to a double array...I've tried cast and even just defining that original int array as a double. all I get is my data being turned to some very large negative values.
Is there a way ard this?
Thnx.

I think you've castet only the pointer.
You will have to make an new array and then cast every value into the new array.

You'd like to think it to be as simple as:
int nNumbers[5] = {2, 8, 8, 7, 0};<br />
double dNumbers[5];<br />
memcpy(dNumbers, nNumbers, sizeof(nNumbers));
but since a double is not the same size as an int, this isn't going to work.
It'll take a few more lines of code, but you'll need something like:
for (int x = 0; x < 5; x++)
dNumbers[x] = nNumbers[x];before calling the function.

Does anyone know how to write a service to forbid execution of a specified application (ie maybe ???)
Thanks for all.

I don't think it is possible to forbid an application from executing. Allthough I know that in XP there is something ( group policies I think ) where you can block certain applications.
What you could do if you want to block an application is use a system-wide hook in a dll and check when a window is created. From that window you can easily get the executable's name and end the process if you don't want it to run...
Don't think you are, know you are...

If the application in question is on an NT-type box, you can alter the security/permissions of it so that only certain users/groups can execute it. When your service tries to execute the application, it will error out accordingly.

I'm not sure to have understood your request well. If you want to display a date in a localized format, have a look to the class COleDateTime, and the member function COleDateTime::Format.

i want to show my window which is derived from CWnd in the button clicked event .the following is my code
void CTmp_dlgDlg::OnButton1()
{
RECT rect;
CString str;
GetWindowRect(&rect);
CMyWnd *mywnd = new CMyWnd;
str = AfxRegisterWndClass( 0);
int ret=myWnd->Create (str,"text",WS_VISIBLE|WS_CHILD,rect,this,1234);
mywnd->ShowWindow (SW_SHOW);
}
CMyWnd::CWnd

Try
void CTmp_dlgDlg::OnButton1()
{
RECT rect;
CString str;
GetWindowRect(&rect);
ScreenToClient(&rect);
CMyWnd *mywnd = new CMyWnd;
str = AfxRegisterWndClass( 0);
int ret=myWnd->Create (str,"text",WS_VISIBLE|WS_CHILD,rect,this,1234);
mywnd->ShowWindow (SW_SHOW);
}

Hi,
I have a CArray - m_array < STRUCT1, STRUCT1 > and I want put his to the CMap < DWORD, DWORD, m_array, m_array >. How to make this?
Best regards,
Eugene Pustovoyt

The simple answer is you can't, not directly. CArray does not have a copy constructor or assignment operator, so it won't work. There are a couple of workarounds however.
1. Make a class that has the array as a member, and define copy constructors and assignment operators that copy the array elements.
2. Derive a class from CArray and implement the copy constructor and assignment operator, and use this class with the map.
I would choose the second option - it is still a CArray, rather than having to go through another class.
Hope this helps,
Ryan
