I'm not sure if Service Packs can be applied to learning edition, but try to download and install SP5. Maybe it'll solve your problems.

You're compiling the program at school and linker barfs? Or you have .exe compiled at home and it crashes at runtime?

I just copy all files except those in DEBUG directory from home to school. Then I rebuild all files in school and run it.

Now seems OK.....but I just worry that it will happen again tomorrow during demo.

So...what happened???

It seems you're compiling on a machine with about 8 megabytes of RAM Smile | :)

Linker just tells you that there's not enough memory to perform link.

Hahahahaaha,

Maybe my home computer is too powerful (AMD900, 512Mb RAM....), but my school's computer just has 256Mb RAM.....

So, basically, I can do nothing except asking the school to replace those computer????

Thank you very much~~~~~~ Laugh | :laugh:

It's more than enough - I don't believe your project is *that* complex. VC installation may be screwed somehow - if it fails on one machine, try with another. Your teacher(s) should be smart enough to get where the problem is.

Here's what the MSDN says about that error...

-------------------------------------------
Linker Tools Error LNK1102
out of memory

There was not enough memory for the tool to run. Probably the paging file exceeded available disk space.

If a shortage of disk space is not the cause, note the circumstances of the error, try to isolate the problem and create a reproducible test case, then consult the technical-support help file or the technical-support section in one of your manuals.

----------------------------------------------------

so check the disk space on your computer.

Hi,

My base dialog(CMyDlg) have 3 buttons and 2 childs windows. Which are delived from CPropertyPage and each have 2 buttons and edit control. My question is how to route focus when user press "TAB". Route focus from 1. after to 2. after to 3. button in CMyDlg and next route it to first childs windows. After when focus has last control (in first child w.) and user press TAB route focus to second child windows and so on ... As you have only 1 base dialog which have all control.

::SendMessage(pWndParent->m_hWnd, WM_NEXTDLGCTL,0,0); I use this but its only for control with WS_TABSTOP Frown | :-(

( not for windows.

Could you suggest some link ? or how to do it ??

Thanks very much

Make sure the property page/child windows have WS_EX_CONTROLPARENT extended style set. You can force this on during initialization.

I need to create two threads at the same time - meaning I cannot wait for one thread to complete before I create the second because they both have continuous loops inside their functions.

What do I need to do in order to create and run both threads? Could you give me some sample code or direct me to the correct function(s)?

Thanks in advanced.

You just create the two threads in sequence. Creating the second thread won't wait for the first to finish.

Use the CreateThread function to initialize two HANDLE variables in your windows callback procedure. By default, the functions/objects associated with the handles will execute concurrently.

Create them both suspended, and then start them. Then ensure you are using whatever synchonization primitives are needed to get your threads working correctly. Go read Threads 101.

When filling the BROWSEINFO struct, provide a callback function.

Use the following:

// global callback fn:
int CALLBACK MyBrowseCallbackProc(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData)
{
  if (uMsg == BFFM_INITIALIZED) {  // kind of "OnInitDialog"
     // 1. retrieve the path from the lpData which was passed with the BROWSEINFO struct
     LPCTSTR path = (LPCTSTR) lpData;
     // 2. send a "select folder" message:
     SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM) path);
  }
  return 0;
}

// when you call it:
LPCTSTR path = "c:\\whatever\\you\\want";
BROWSEINFO binf;
// fill binf as usual
...  
// watch magic:
binf.lpfn = MyBrowseCallbackProc;
binf.lParam = (LPARAM) path;

pidl = SHBrowseForFolder(&binf);

Happy coding

Hi, the following code is in a function. I'm doing multithread. When my thread function call this function, i got error message and program terminate......what happened????? HELP!!!!!

{
cs.Lock(); //Critical Section Lock
std::vector <SCHEDULER_MESSAGE>::iterator Scheduler;
if (!Scheduler_MSG.empty())
{

for ( Scheduler = Scheduler_MSG.begin() ; Scheduler != Scheduler_MSG.end() ; Scheduler++ )
{

if (((*Scheduler).msg == ABORT_MSG) || ((*Scheduler).msg == COMMIT_MSG))
{

std::vector <WAITQUEUE_STRUCT>::iterator Iter;

for (int i=0; i<NumOfDBObject; i++)
{
if (LockTable[i].CurrentThread == (*Scheduler).pThread)
{

LockTable[i].CurrentThread = NULL;
LockTable[i].CurrentLock = CurrentNoLock;
}

if (!LockTable[i].WaitQueue.empty())
{
for ( Iter = LockTable[i].WaitQueue.begin() ; Iter != LockTable[i].WaitQueue.end() ; Iter++ )
{
if ((*Iter).pThread == (*Scheduler).pThread)
LockTable[i].WaitQueue.erase(Iter);
}
}
}

Scheduler_MSG.erase(Scheduler); //Finished and erase this message

}

}
}
cs.Unlock(); //Critical Section Lock

Using erase on a vector invalidates the iterators.

Maybe if you changed your loop to...

while (!(!Scheduler_MSG.empty())
{
    Scheduler = Scheduler_MSG.begin();
    .... the rest of the code
}

So i change the code liked this:

while (!Scheduler_MSG.empty())
{
Scheduler = Scheduler_MSG.begin();
AfxMessageBox("Update start");
if (((*Scheduler).msg == ABORT_MSG) || ((*Scheduler).msg == COMMIT_MSG))
{
//AfxMessageBox("In the IF loop");
std::vector <WAITQUEUE_STRUCT>::iterator Iter;

for (int i=0; i<NumOfDBObject; i++)
{

if (LockTable[i].CurrentThread == (*Scheduler).pThread)
{
LockTable[i].CurrentThread = NULL;
LockTable[i].CurrentLock = CurrentNoLock;
}

if (!LockTable[i].WaitQueue.empty())
{
for ( Iter = LockTable[i].WaitQueue.begin() ; Iter != LockTable[i].WaitQueue.end() ; Iter++ )
{
if ((*Iter).pThread == (*Scheduler).pThread)
{
LockTable[i].WaitQueue.erase(Iter); <=====Something wrong here...
}
}
}
}

//AfxMessageBox("Before erase");
Scheduler_MSG.erase(Scheduler); //Finished and erase this message
//AfxMessageBox("After erase");
}

}

I found something wrong in the statement LockTable[i].WaitQueue.erase(Iter); (stated)... when i disable this line.....it's no terminate message.........how to change it?

Thanks!!!!!

It is the exact same problem. Calling erase invalidates the iterator.
