I am programing a Socket with SSL,so i m using various header files for encrytion,ssl protocol
#include <wincrypt.h>
#include <wintrust.h>
#include <Schnlsp.h>
(these header files r in stdafx.h)
when i compiling my program is showing errors,eg
c:\program files\microsoft visual studio\vc98\include\schnlsp.h(118) : error C2501: 'ALG_ID' : missing storage-class or type specifiers
when click on the error
typedef struct _SecPkgCred_SupportedAlgs
{
DWORD cSupportedAlgs;
ALG_ID *palgSupportedAlgs;
} SecPkgCred_SupportedAlgs, *PSecPkgCred_SupportedAlgs;
when i check this strucure in msdn i found data type ALG_ID is defined in the Wincrypt.h header file.
when i check wincrypt i found that a macro has to be define
#if(_WIN32_WINNT >= 0x0400)for using wincrypt.h
so i defined #define _WIN32_WINNT 0x0500 in stdafx.h before any header file is defined
now when i again compile the program
D:\sunit\controleon\Working\CSocket\sslsocket.cpp(611) : error C2039: 'dwFlags' : is not a member of '_SCHANNEL_CRED'
c:\program files\microsoft visual studio\vc98\include\schnlsp.h(129) : see declaration of '_SCHANNEL_CRED'
i found the struct _SCHANNEL_CRED in schnlsp.h file
typedef struct _SCHANNEL_CRED
{
DWORD dwVersion;
DWORD cCreds;
PCCERT_CONTEXT *paCred;
HCERTSTORE hRootStore;
DWORD cMappers;
struct _HMAPPER **aphMappers;
DWORD cSupportedAlgs;
ALG_ID *palgSupportedAlgs;
DWORD grbitEnabledProtocols;
DWORD dwMinimumCipherStrength;
DWORD dwMaximumCipherStrength;
DWORD dwSessionLifespan;
} SCHANNEL_CRED, *PSCHANNEL_CRED;
where as in msdn
typedef struct _SCHANNEL_CRED
{
DWORD dwVersion;
DWORD cCreds;
PCCERT_CONTEXT * paCred;
HCERTSTORE hRootStore;
DWORD cMappers;
struct _HMAPPER ** aphMappers;
DWORD cSupportedAlgs;
ALG_ID * palgSupportedAlgs;
DWORD grbitEnabledProtocols;
DWORD dwMinimumCipherStrength;
DWORD dwMaximumCipherStrength;
DWORD dwSessionLifespan;
DWORD dwFlags;
DWORD reserved;
} SCHANNEL_CRED, *PSCHANNEL_CRED;
as in my proram i m using dwFlags
i m not understanding where is the problem.
Thanx for any suggesstion

Does anybody have any idea about where the resources are defined for Standard Message Boxes i.e. in which file and its path ? . What I mean to say is that how App knows to show OK string.I mean it can show Cancel string instead of OK. From where it loads those string. This must be in some rc file(Thats my assumption). Any idea. Any help would be appreciated.
Best Regards,

As MessageBox api is defined in User32.dll, So law of Common sense it might be in User32.dll only  , just kiddin..

Okay. but when I delete user32.dll from System Folder why does it comes again. From where the windows loads it again. Also if I replace user32.dll with other version(language) of WinXP, it again loads the default one. Any reason . How to cope with it ?

Windows 2000 also has this feature. It's called WFP. Comes in handy when some nefarious program steps on those important files.

Just wondering if anyone knows if there are converters to convert from:
MS Visual C++ 6.0 or
MS Visual Studio 2003
project files into UNIX autogen/configure/make files?
|

With VC++ v6, you can export to a makefile. Look in the Project menu.

Yes there is the export feature in VC 6.0. However I don't see any export feature in Visual Studio .NET 2003. Hmmm...

Does anyone know how LoadImage (from win32 API) works, when loading RLE8 bitmaps? I know that this function can convert RLE8 bitmaps to BI_RGB format. In dibutil.c (from MSDN) you can find function that can change dib format from BI_RGB to RLE8. I tried to revert that, so I used CreateDIBSection with ppvBits pointing to RLE8 data. Now GetDIBits with biCompression set to BI_RGB doesn't work. I don't know why - as I said earlier - LoadImage can load RLE8 bmps, so - there must be functions that I could use to do this conversion.

I developed a simple application in MFC. First I ran it in Win XP English ok was everything was normal. Next when I ran the same exe in Win XP French, the text on the button of MessageBoxes was in French. I am using the same exe, no Remote Dlls and no change in rc File. So why is it such a difference ? ... I mean should the text on the button of MessageBoxes be not the same as in WinXP English. Any logic or reasoning behind it ?
Regards

windows behaves as the user installed it for...
if you are english, you expect windows to speak englisk to you, if you are french (i am), it better if windows can speak french to you...
it is because windows search in priority the default windows language first, then some others (i don't remember the whole list, but the MSDN will give you the answer)...

hi..
I have a multiple view program. One of them is CListView in report style, with full row select. but now when i increase the initial size of the columns by dragging the column header , the selection mark will be shown only till the initial size of the columns the remaining portions are not updated. what is to be done to update the remaining portion of the view
thanks ....

Something else must be at play here. I just tried this with a multi-column list control and sizing any of the columns caused the selection mark to grow/shrink accordingly. Try scaling the problem down to just a small, test application that does nothing but add a few items to a multi-column list control.

hi..
i have a hiden column in my list . to avoid it from shown to the user
to prevent it from showing the headers onitemchanging is overridden
the code is as follows
CMyView::OnItemchanging(NMHDR* pNMHDR, LRESULT* pResult)
{
HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;
// TODO: Add your control notification handler code here
if((phdn->hdr.code ==HDN_ITEMCHANGING)&&phdn->iItem ==0)
{
*pResult = TRUE;
return ;
}
*pResult = 0;
}
but calling RedrawWindow() in onitemchanged of list view solved the problem.
but i dont know if this will have some perfomance problems .
if there any way in which i can solve the problem.
thanks...

hi..
yes to stop the user from resizing the first column i overrided the header item change message like
void CMyView::OnItemchanging(NMHDR* pNMHDR, LRESULT* pResult)
{
HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;
if((phdn->hdr.code ==HDN_ITEMCHANGING)&&phdn->iItem ==0)
{
*pResult = TRUE;
return ;
}
*pResult = 0;
}
probably this was the cause.
any how calling RedrawWindow() in item changing solved the problem.
code is like
void CDirView::OnItemchanged(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
if(m_nNoItemChange && LVIS_SELECTED == m_List.GetItemState(pNMListView->iItem,LVIS_SELECTED))
{
//my neaded code here
}
*pResult = 0;
RedrawWindow();
}
but i dont know if this is a proper methord. and i would like to know if i can set the size of each column in onitemchanging of header.
thanks...
