Hey Guys,
My name is Danny Nowlan and I'm currently working on an app using Visual C++ 6, that loads an SDI application using a DLL.
I'm having an intermittant problem in release mode with some WinXP machines where the DLL won't load at all in release mode. It doesn't even get to InitInstance() In the dll. In debug mode it is perfect. The bugger is it only happens on a handful of WinXP machines
Is there a way of looking at the source code that loads the dll into my application. That way I can put in some statements etc so when I compile in release I can see what is going on.
Thanks guys
Danny

~RaGE();,
The first article really helped. It discussed compiler optimisations, and the moment I turned it off it worked like a charm.
Thank you so much.

Hi,
I want to copy the entire content of a hard disk to another one. The second hard disk should be an exact image of the original one, after the copying process.
How to do this using VC++ or C++ or C?
Please suggest me the way of approach that I have to adopt.
Hoping to get a reply soon.
TIA.
regards,
Jahfer V P.

Unless you are looking for something difficult to do, I would spend $20 on a copy of Ghost. It's well worth it.

Yes, or setup RAID if that's what you want to accomplish with this.

Is this only for one pc or many? Is this for a client? Are the disks the same size? I ask these questions because linux has a very easy utility to do this. The command is dd. I recently found this when partition magic failed to copy a failing hard drive because it han not been unmounted cleanly. Of course it was unmounted cleanly XP locked up when the disk stoped spinning. Good thing after a reboot it started spinning again... I booted off a gentoo linux live cd and at the prompt I typed dd if=/dev/hda of=/dev/hdb bs=8M and in about 1 hour I had a copy of a 40 MB drive on an 80 MB drive. It did not resize the partitions though but after removing the smaller bad disk windows XP booted and ran fine.

I sure hope that those MB's were worth the waiting.

 I do this all the time. I guess it shows my age... I actually had both drive sizes on my main computer sometime in the mid to late 80s. I remember that the 80MB drive cost almost $800 and that was for a drive that had hard errors on it. Since dos 3 did not support partitions above 32 MB I remember I had to split it into multiple partitions...

I used Oscilloscope control in win32 and i always get an error while graph was plotting data
"Unhandled exception in sm85032.exe (UOPORT.DLL): 0xC0000005: Access Violation."
as i debug into the code the source of the problem was an error in freeing a "POINT" type
pointer variable in the oscilloscope header.
Would there be any problem if i use WTL code in win32?
or is there anything i should set before accessing WTL code.
Any hints on this one.
Thanks!

Please show the code for freeing the pointer.
Some functions throw exceptions when freeing memory which was never allocated.
And there are no problems when using WTL in Win32 as far as I know.
this is this.

Here is the code from the header file of the Oscilloscope control
http://www.codeproject.com/wtl/WTL_Oscilloscope.asp[^]
void SetPoints(size_t time, double* values, size_t count)<br />
{<br />
m_time = time;<br />
m_values = values;<br />
m_pointsCnt = count;<br />
<br />
if (m_points) <br />
delete [] m_points;
m_points = new POINT[m_pointsCnt];<br />
<br />
_UpdateYRange();<br />
_Recalc();<br />
}<br />
One thing is that these line do not encounter error not until the 18th time it was accessed so im wondering why?
Any suggestions? Thanks!

If you were asking for how to draw them, maybe following charting controls may help you:

If you were asking for how to get the data, that's a math problem, please post again with more details.
Hope this helps

Hi!
I've developed a dialog based application using MFC. In the application I've created an edit box dynamically. On the edit box I do some validation and displays messagebox and sets the focus on the edit box using SetFocus().
The problem I'm facing is, after the validation though the focus goes back to the edit box but the cursor does not blinks as it do initially which can be confusing to the end user.
Kindly help on this!!
Thanks.

Try calling setCursor when you get focus on the edit control.

Hello All,
I have created a DLL that has an export which calls CreateDialog to make a modeless DLL.
CreateDialog(hDLL, MAKEINTRESOURCE(IDD_DIALOG1), mWnd, (DLGPROC)DlgCallBack);
When called, the dialog pops up and everything seems to go right... but locks-up as soon as i click or drag mouse into the dialog. My guess is that something might be going wrong with the way I handle messages or something weird caused by using a dll that I am not aware of, but am not sure since i am new to windows programming. Here is the code in my callback
<br />
switch(uMsg)<br />
{<br />
case WM_COMMAND:<br />
<br />
switch(wParam){<br />
case IDOK:<br />
return TRUE;<br />
}<br />
break;<br />
<br />
case WM_DESTROY:<br />
PostQuitMessage(0);<br />
return true;<br />
<br />
case WM_CLOSE:<br />
DestroyWindow(hwnd);<br />
return TRUE;<br />
<br />
}<br />
<br />
return FALSE;<br />

Did you mean modeless dialog?

Could you explain a bit on what you mean by that.

Thnx to both of you.... Sorry for the late reply
Sorry for not properly specifying, but by locking up i ment the infamous "<the app="" calling="" my="" dll=""> has encountered a problem and needs to close" was poping up. For further clarification on what causes this lock up, this occurs anytime I click on the window of the app (mIRC) that calls my dll or move the mouse into my dialog's window. Anyways, after using DefDlgProc, this problem goes away, but the calling app (mIRC) immediately terminates without notice. Any ideas?
