Well, up until a few days ago I thought it was impossible, but I noticed that occasionally x64 version of NTDLL was loading the x86 version of NTDLL into a x64 program.
I don't know how it is done, perhaps 1 of the many undocumented APIs.
In the past I have created a x86 helper .exe which loads the DLL, and returns whatever. This can be done with Remote Procedure Call, but I only ever used pipes.
EDIT: It may be loading them for resources rather than code with LoadLibraryEx, which should be allowed

Hi
i am beginner of win32 Vc++. I create Menu item and call File open dialog box. I have a File Menu. it contains Open, save and exit menu items.I have file open dialog box function. Open menu item id is: ID_FILE_OPEN.

case WM_COMMAND:
switch(wParam)
{
case IDOK:
EndDialog(hWndDlg, 0);
return TRUE;
case IDCANCEL:
EndDialog(hWndDlg, 0);
return TRUE;
case ID_FILE_OPEN:
OnFileOpen(hWnd, ID_FILE_NEW, 0, 0);

But error is come like ID_FILE_OPEN' : undeclared identifier
how to fix this?

In your menu in the Resources window you will have specified a value for the menu item File>Open. You can find this value in the properties window (View->Other Windows->Properties Window) and click on the Open item in the file menu in the resource editor.
The value will also be #define'd in the Resource.h file, so be sure to #include "Resource.h"

When we press Shift+Delete key, a delete confirmation dialog is generated. I want to handle this dialog according my need or change its message. Can anyone tell me what thing is responsible for that dialog?
I either need to know the code which handles the delete confirmation dialog generated by the Shift+Delete key sequence in Windows XP, or the code by which we can control this operation.
|

|
|
|
Take a look at Classic Shell[^]
It replaces the Copy dialog, surely the same principal can be applied to delete

Well, firstly you would need to decode the MP3 data. No point reinventing the wheel, just use something like LAME[^]
Then you need to draw it to the screen somehow. If you are using Windows, I might suggest GDI+[^]
The scope is the most basic audio analysis visual to make... all you are essentially doing is displaying the value of the data at each sample, so just draw it like a massive line graph mapping sample number vs. sample value

For the plotting part, there's a couple of chart controls on CP. You can also have a look at my sig for one of them that I developed.

Hi,
I deveopled a MFC appliocation using visual studio 2008. It is running fine on double clicking the exe but If I launch the same application using installer (install shield) it is not lanching and producing a exception.
What might be the cause?
|
|
|
|
|
Perhaps an exception code, minidump, memory snapshot, anything could help, attatch the visual studio debugger as a JIT debugger.

As soon as IO try to launch the application using installer I get the below exception:
Problem Event Name: APPCRASH
Application Name: Myapp.exe
Application Version: 6.3.11.0

Exception Code: c0000005 is a protection fault. You tried to read/write to a bad memory address. Although it says the error occurred in ntdll, it is most likely an argument you passed into a function in there.
Try attaching a debugger to the process when it is in the crashed state to see the call stack. At a rough guess I would say it is something to do with your command line processing
|
|
|
|
|
But If I run the application using clicking the exe, it is running and same exceptino is coming after quit the application.
But If I run application as Admin, It works fine.
What is the problem?
|
|
|
|
|
Then your code must do something that requires Admin rights (in the Cleanup) and you aren't handling the error properley.
There is a vast number of things that this could be, but there is a fair chance that it is with a file. The Program Files and Windows directory are protected if UAC is enabled (Win Vista/7).
For example, if you open a file in a protected location and try to read it without checking that it is open you may be using invalid data.

May be you will have to install the VC++ 2008 redistributable as well.
|
|
|
|
|
Although some people define "crash" rather generally, if it was missing the runtimes it would generally show a message saying something like "the application failed to initialize. The application configuration is incorrect"
|
|

That's mean it doesn't work on another machine?
If the answer is yes then you probably have to deploy VC runtime and/or MFC DLL (see, for instance, http://msdn.microsoft.com/en-us/library/8kche8ah(VS.90).aspx[^]).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

In addition to what others suggested, please make sure all the dependent files ( lib and dll) are located by your installer app.
Hope this helps

Hi all,
How can i get this below string.
For example:
I want to pass string as phone+="984512345".
I am trying with below code.
CString str = "phone+=";
str += "984512345";
Output:str = phone+=984512345.
I am not getting that "984512345".
How can i add " to that string
Thanks
Raj

If I well understood, you want the " into the final string.
Try
CString str = "phone+=";
str += "\"984512345\"";

Hi All.
A very simple question, but so far not able to find any concrete solution.
I just want to round a decimal value to a provided decimal place.
I have found few functions to do the same, but they also fail for some double values...like...
double Round1(double dbVal, int nPlaces)
{
const double dbShift = pow(10.0, nPlaces);
return floor(dbVal * dbShift + 0.5) / dbShift;
}
double Round2(double value,int pos)
{
double returnValue;
double tens = exp(pos*log(10.0));
if((value - floor(value*tens)/tens)*tens >= 0.5)
returnValue = ceil(value*tens)/tens
else
returnValue = floor(value*tens)/tens;
return returnValue;
}
Both of above function fails in case the double value is
10430.889999999999
464.45999999999998
3294.5100000000002
Please suggest.
Thanks
PanB

I haven't looks at Round2, but cannot imagine a case where you would need to use exp and log to round.
