I've used VC++7 to write a program that gets some iformation from another program, parse it, do calcualations, and output the result.
It's working well on WinXP and Win2K.
However, I need it to work on WinNT (my friend need it). When he tries to run the program, a message shows up "Initialization of the dynamic link library C:\WINNT40\system\OLEACC.DLL failed. The process is terminating abnormaly".
Has anybody gone through a similar situation, or knows anything about it? Do you think that I should change something in the program, or the problem is because of the dll only?
Thanks

// the parent class of CBtnEx is COleControl
CBtnEx::CtrlSetBitmap(.............)
{
SetWindowPos(NULL,0,0,20,20,SWP_NOZORDER ); // takes no effect.
}
CMyDialog()
{
m_btnEx.CtrlSetBitmap(.....);//
m_btnEx.SetWindowPos(NULL,0,0,20,20,SWP_NOZORDER ); // it works ,
// the only way is calling outside the class ?
// what should I do ?
}

even if the file is altered in your IDE, it will display such dialogs. [for example, if u change something in the dialog and try to complie it, though it doesn't throw any errors]. just click on "save all" before compiling. this will make sure what you see is what is there.

I have a class written in WTL 7.0 but I want to use it in my MFC application.How can i do that. The class use WTL CString but I think it isn't recognized in MFC
I tried to add the class into my project but I got the following code when I conpiled:
fatal error C1010: unexpected end of file while looking for precompiled header directive
Can you help me?
Thanks a lot!
|
|
|
|
|
well,
I am not too sure about WTL->MFC, but you can fix the compilation error by putting
#include "stdafx.h"
at the top of the file or select "not using precompiled header" in projectsettings->C/C++

Thank you for your help.
When I debug the program and close it ,it said the "HEAP[Airrf.exe]: Invalid Address specified to RtlValidateHeap( 00370000, 003750AC )". What does it mean?And How do i work it.
Thank you.

it probably means you've written outside the memory your app has allocated (you have a stray pointer somewhere) and you've corrupted something the OS needed to maintain the Heap.

Thank you.
So how to I deal with it? Could you give me some ways to find the error pointer?
|
|

this is definitely a difficult thing to track down. basically, you have to make sure any pointer you use points to a valid address before you write to it.
basic things to start with: make sure your pointers are initialized to NULL or a valid value before you use them. take a good close look at any code that dereferences a pointer (*(ptr) = ..; , ptr[x]=...; or ptr->... = ...;) - make sure that code isn't running outside the limits of any memory you've allocated dynamically...

Thank you for your help.
I will track down any code defined the pointer.
Thank you again.
|
|
|
|
|
and if you are free up a memory pointer dont forget to assign NULL to that (good practice)
