actually the base class is processing the message.
so you should override it.
|

probably i should explain in more detail.
1st, it is a modeless dialog. and i want to limit to one instance of the dialog for one button. thus i reset the one variable( in PostNcDestroy()) each time the dialog closes.
if the dialog closed by "cross", it is no probablem to open it again. if you press "enter" in the combo box, then it wont open again. that means PostNcDestroy() is not called.
i wonder it is the combo box that close the dialog when it receives a "enter" key.
so i am stuck here now....
thanks for the help.

insert these lines to your program
<br />
ON_BN_CLICKED(IDOK, OnBnClickedOk)<br />
<br />
void CYourclass::OnBnClickedOk()<br />
{<br />
}<br />
<br />
public:<br />
afx_msg void OnBnClickedOk();<br />
<br />

Hello,
I need to get motherboard serial number in C++ (VS6) environtment without using WMI (need to run under Win98). Does anybody know how to do that?
Thanks

|
|
|
|
But there is nothing about getting motherboard id

I redistribute this inside my .msi's so WMI is available on WinNT installations. I don't support 95/98 but it appears that it will work with 95/98/NT. (Already installed on Me/2000/XP)
I have verified that this works on WinNT at a minimum. Be forwarned that the WMI service can be disabled by users who have access to Administrative management GUI's so make sure you check for it's presence before assuming it's running.
Windows Management Instrumentation (WMI) CORE 1.5 (Windows 95/98/NT 4.0)[^]

Look up
"Win32_BaseBoard","SerialNumber"
Be forwarned, that sometimes this value is not available (empty or null or numerous space characters) so if your using this to perform some form of software license verification (that's what I use it for) you will likely want to include a few other, rarely modified hardware numbers like
"Win32_Bios","SerialNumber"

Hi all,
I have explored the MSMQEvent in VC++. But i can't get a Clear Picture, which is used to Capture the Arrival of any Message from the End User to invoke the MSMQ Service.

CPage* pPage = new CPage(rect,pDC,MM_ANISOTROPIC);
//create and use a table

Hi all,

you can call GetAsSystemTime function of CTime to get SYSTEMTIME structure used to store the time. from that you can access milliseconds and other information supported
one more.
GetAsDBTIMESTAMP is also there you can get the fraction represents billionths of a second ranging from 0 to 999,999,999.
Note This method is only available when OLEDB.h is included.
See MSDN for more details.

Use GetSystemTime(LPSYSTEMTIME lpSystemTime), which works with a pointer to SYSTEMTIME as argument:
typedef struct _SYSTEMTIME {
WORD wYear;
WORD wMonth;
WORD wDayOfWeek;
WORD wDay;
WORD wHour;
WORD wMinute;
WORD wSecond;
WORD wMilliseconds;
} SYSTEMTIME;

Hi,
I have developed an application which creates .mdb files in a specific folder named store. This folder is created during installation. But when the program is uninstalled, since there are additional(new) files in the folder store, the folder does not get deleted from the computer.
I thought, maybe I should create a small .exe program that deletes all the .mdbfiles from the store folder before the uninstall is run.
The problem here is that I do not know the names of the files in the folder. Is there anyway or any function by which I can find and delete all .mdb files from the folder store?
Thanks.

Is this good?
<br />
WIN32_FIND_DATA find; <br />
SetCurrentDirectory("c:\\temp"); <br />
HANDLE handle=FindFirstFile("*.mdb",&find);<br />
while(FindNextFile(handle,&find)!=0)<br />
DeleteFile(find.cFileName);<br />
FindClose(handle);<br />
or you can use from
|
|
|
|
|
Because you do findfirst() and findnext() before you do DeleteFile(), I think this will leave one mdb file behind.
|
|
|
|
|
No problem we can use from a Do while and yes its right.
<br />
WIN32_FIND_DATA find; <br />
SetCurrentDirectory("c:\\temp"); <br />
HANDLE handle=FindFirstFile("*.mdb",&find);<br />
do<br />
DeleteFile(find.cFileName);
while(FindNextFile(handle,&find)!=0);<br />
FindClose(handle);<br />
|
|
|
|

This is the program that I tried.
#include "afxdisp.h"
void main()
{
WIN32_FIND_DATA find;
char aExePath[_MAX_PATH];
char aDrive[_MAX_DRIVE];
char aDir[_MAX_DIR];
CString aPath;
::GetModuleFileName( AfxGetInstanceHandle(),aExePath,sizeof(aExePath));
_splitpath(aExePath,aDrive,aDir,NULL,NULL);
aPath.Format("%s%s",aDrive,aDir);
aPath = aPath + "sbh_store";
SetCurrentDirectory(aPath);
HANDLE handle=FindFirstFile("*.mdb",&find);
do
DeleteFile(find.cFileName);
while(FindNextFile(handle,&find)!=0);
FindClose(handle);
}
Here I get the error
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
When I comment out
CString aPath;<br />
::GetModuleFileName( AfxGetInstanceHandle(),aExePath,sizeof(aExePath));
I do not get the unresolved external symbol error. I guess I am missing something.
Please can you tell me what I am not doing right. Have I missed out a header?
