Dear Shiva,
I too experianced the stack correption problem in one of my projects. The reason was, if you had classes of big size, dont create then on stack, but create them on heap.
Another possible reason may be with exception handling. In our project we are throwing an exception object which is very big in size. So when the system enters into a funciton, it calulate the maximum stack that is needed. So, in exception handling mechanism, we throwed the same object many number of times in the same function, when some error cases come. In our sense as only one throw can work at a time, the system will calculate the stack size with that single exception object. But C++ calculates the stack size as ( total number of throw objects * size of single object ). thats the reason.
Hope this can help you.
Regards,
Jijo.

Do anyone how to make a simple application to link a computer to a mobile phone using visual c++. If anyone has an idea or knows the source code for it can u please help me out.
Thanks!!

What mobile phone model are you talking about ?
Nokia releases and upkeeps the Nokia PC Connectivity SDK, which allows you to programmatically control a phone connected to your computer via Nokia serial cable, USB cable, Bluetooth or IrDA.
I believe Ericsson and other manufacturers have similar SDKs. They all come with a proper documentation and lots of examples. Consult these for more help.

Hi
I am getting list of files in given directory using FindFirstFile() and FindNextFile() function. But it shows directory as well as files. How can I know that which one is file and which one is directory ?
Or
Is ther any specific function which gives only files or only directory ?
Plz Help me.
I am in Hurry...
Thanking you
Atmiya

If you read the documentation in MSDN for FindNextFile you will see that the second parameter is a pointer to a WIN32_FIND_DATA structure. That structure first member is dwFileAttributes. All you do is check if the FILE_ATTRIBUTE_DIRECTORY bit is set. If it is, you have a directory, else you have a file.

U can use..
if(GetFileAttributes(file_r_dir_name) == FILE_ATTRIBUTE_DIRECTORY)
{
//it's a directory
}
else
{
//it's a fil
}
|
|

Won't work as expected. You have to check the FILE_ATTRIBUTE_DIRECTORY bit only. Directories can be hidden, compressed, readonly etc.
if (GetFileAttributes(file_r_dir_name) & FILE_ATTRIBUTE_DIRECTORY)

Hi !
I create a UI Thread in my software and I am sure that it is created because I have a breakpoint in the InitInstance function which only Return TRUE; At this point, I know that the message pump of this thread is running. (Is it right ?)
I use PostThreadMessage() to send a user message to my thread. It seems that the message is never sent. I try to use SPY++ with this thread and I don't find them. I find the main thread of my software but not the UI Thread created by me (This is a derivative of CWinThread). I want to see all messages for this thread in SPY++. I use it for the first time and I understand how it work which other thread and process. It does'nt work for my thread.
Do you have any idea ?

No, the message loop does not begin until after InitInstance() returns. If it returns FALSE, the message loop is never entered.

What did PostThreadMessage() return? Show us the code you used to call PostThreadMessage().

Thanks Ryan !
My InitInstance() function is the one given by Wizard. It returns TRUE and it works. (I saw it with debugger).
Here is a part of my code.
// Create Thread.
m_pUIThreadTestPlan = (ThreadTestPlan *) AfxBeginThread( RUNTIME_CLASS(ThreadTestPlan));
// Start the execution of all activities in the thread.
m_pUIThreadTestPlan->PostThreadMessage( WU_UITHREAD_TESTPLAN_START, 0, (LPARAM) thread_info);
thread_info is a structure with some information for the thread.
Here is the message map for the handler of my WU_UITHREAD_TESTPLAN_START message.
BEGIN_MESSAGE_MAP(ThreadTestPlan, CWinThread)
//{{AFX_MSG_MAP(ThreadTestPlan)
ON_THREAD_MESSAGE(WU_UITHREAD_TESTPLAN_START, OnStart)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
And for sure, I have a function named OnStart().
LRESULT ThreadTestPlan::OnStart(WPARAM, LPARAM lp)
{
// Something inside here.
With my debugger I never ENTER here. NOTHINGS HAPPEN.
}
The other point is I don't see The THREAD in SPY++.

Hmmm, this seems to suggest that the thread doesn't exist. Spy++ should be able to see it if it's there... Are you sure the thread is being created correctly?

Ok thank you Ryan ! I found the result on www.MSDN.com
Here is the result.
// Generated message map functions
//{{AFX_MSG(ThreadTestPlan)
afx_msg LRESULT OnStart(WPARAM, LPARAM lp);
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
static UINT NEAR WM_TEST_PLAN_START = RegisterWindowMessage("WM_TEST_PLAN_START");
I register my message and I call the message handler (my function) via message map with ON_REGISTERED_MESSAGE.
ON_REGISTERED_MESSAGE(WM_TEST_PLAN_START, OnStart)
I hope it won't generate another error.

Can anyone plz tell me how to use a function which is taking parameter as UNICODE into ANSI or such that it takes parameter as char. Or How to convert parameter from char UNICODE and UNICODE to ANSI ?
I am using function NetShareEnum : the example is same as given in MSDN. Also given below... What needs to be changed so that I can use main() instead of wmain() like...void main(int argc, char* argv[])...instead of (int argc, TCHAR* argv[])...
#define UNICODE
#include <windows.h>
#include <stdio.h>
#include <lm.h>
void wmain( int argc, TCHAR *lpszArgv[ ])
{
PSHARE_INFO_502 BufPtr,p;
NET_API_STATUS res;
LPTSTR lpszServer = NULL;
DWORD er=0,tr=0,resume=0, i;
switch(argc)
{
case 2:
lpszServer = lpszArgv[1];
break;
default:
printf("Usage: NetShareEnum <servername>\n");
return;
}
//
// Print a report header.
//
printf("Share: Local Path: Uses: Descriptor:\n");
printf("---------------------------------------------------------------------\n");
//
// Call the NetShareEnum function; specify level 502.
//
do // begin do
{
res = NetShareEnum (lpszServer, 502, (LPBYTE *) &BufPtr, -1, &er, &tr, &resume);
//
// If the call succeeds,
//
if(res == ERROR_SUCCESS || res == ERROR_MORE_DATA)
{
p=BufPtr;
//
// Loop through the entries;
// print retrieved data.
//
for(i=1;i<=er;i++)
{
printf("%-20S%-30S%-8u",p->shi502_netname, p->shi502_path, p->shi502_current_uses);
//
// Validate the value of the
// shi502_security_descriptor member.
//
if (IsValidSecurityDescriptor(p->shi502_security_descriptor))
printf("Yes\n");
else
printf("No\n");
p++;
}
//
// Free the allocated buffer.
//
NetApiBufferFree(BufPtr);
}
else
printf("Error: %ld\n",res);
}
// Continue to call NetShareEnum while
// there are more entries.
//
while (res==ERROR_MORE_DATA); // end do
return;
}

The easiest way is to #include <AtlConv.h> and use the A2W macro.
USES_CONVERSION;
res = NetShareEnum (A2W(lpszServer), 502, ...
Look up "ATL and MFC String Conversion Macros" in MSDN.

In my app i have a bitmap button
i set the bitmap of the button like so
m_BrowseFile.SetBitmap( LoadBitmap( AfxGetInstanceHandle(), MAKEINTRESOURCE( IDB_OPEN ) ) );
now in the bitmap file the background is gray, and that gray area is showing up
how do i get rid of the gray background?
|

Use LoadImage() instead of LoadBitmap(), and specify the LR_LOADMAP3DCOLORS and LR_LOADTRANSPARENT flags.
m_BrowseFile.SetBitmap((HBITMAP)LoadImage(AfxGetResourceHandle(),
MAKEINTRESOURCE(IDB_OPEN),
IMAGE_BITMAP,
0, 0,
LR_LOADMAP3DCOLORS | LR_LOADTRANSPARENT));

 In my project, I need to automate the process of building a new network connection. You can manually set up a new connection as the following: "Control Panel" -> "Network Connections" -> "Create a new connection" -> Click "next" -> "setup an advanced connection" -> next -> ... We can assume that it is fixed process.
Is there any scripting tool or Windows API which I can use to automate the above process in my VC++ program? Anybody can give me a hint? Thanks a lot

Hi Jeff,
You can use the RAS API (Remote Access Service) to solve your problem. There's examples how to use it in MSDN.

HI~
struct b
{
LPWSTR c;
}
struct a
{
b* d;
}
a* e;
e = new a[100];
a f;
f.d = new b[1000];
b g;
g.c = _T("HIHI");
f.d[0] = g;
e[0] = f;
if I delete pointer e by this statement:
delete [] e;
can it free all the memory including the dynamic array (pointer d) in structure a and the LPWSTR type string pointer in structure b?
or I need to free pointer d first or free pointer c first?
thanks

No, you shouldn't point the existing pointer with new a[100] assigned
to another pointer. Doing so will cause the memory leak of size struct a * 100 cause the system find no way to reclaim back the memory you allocated, the address that the pointer point to has changed.

that is some weird code.
If you run it I think f.d = new b[1000]; will not be deleted
You dont always want to delete this pointer though because some times it is pointing to data on the stack, f.d[0] = g;
Basiacally what you have here is a big mess.

Is it possible to use animated cursors or small animated gifs as bitmap on a toolbar. My search on google and here did not turn up anything.
|
|
|
|
|
Everything is possible.
But, doing what you describe requires that you create a custom toolbar control that animates the buttons. Windows standard toolbar does not provide the functionality you require.
Easiest way to start is to search here on CP for animatable buttons. Then laden these buttons in a row over a Rebar control, and attach it to the top of the window. It works just like a toolbar, but is made and upkept by you.
