Visual C++ :: Passing Message Using Active Directory?
Jan 29, 2015I have a DLL developed using pure VC++ (all unmanaged code that doesn't use .NET framework). This DLL will be deployed in different client PCs within a network and will act like an agent.
Now I have establish a communication between this DLL and a WCF web service, that will be deployed in a server PC. The Service will first get a list of PCs either name or IP Address within a network using LDAP (Active Directory) and once, we get the PCs, I have to establish a communication between the web service and the agents that reside in these client PCs,
How can I accomplish this?
C++ :: Random Partition Into K Groups
Aug 31, 2012How do you generate a random permutation of numbers from 0 to N without storing it in an array ? Note that duplicates are to be avoided so I can't use rand() calls to generate them. The problem I have is to partition N number of data points into k groups in random selection manner. I thought of random shuffling of indices using random_shuffle of stl but the indices need to be stored in an array. Is there a way to get N integers from [0..n] sorted in a random order, using which I can access a database ?

May 18, 2013I am supposed to write a recursive function which find the partition of a number n ,, for example if n=3 , it should print 1 1 1 , 1 2 , 3
I wrote the program but i am getting the two partition 1 2 and 2 1 which are the same ,, how can i avoid that ?
this is the code :
void PrintPartition( int n , int A[] , int j ) {
if( n<=0 ) {
printArray( A, j );
return ;
} for( int i=1 ; i<=n ; i++ ) {
A[j]=i;
PrintPartition( n-i , A ,j+1 );

Apr 27, 2013I've just integrated the Windows SDK V7.0A into my VS2005 application, and I'm getting the dreaded "Application configuration error" when I try to run it on an XP machine.
It runs fine on the development machine, and some customer machines (Win7 and Win8), but will not run on XP due to missing/incorrect version dlls.
I've rebuilt all my libraries, but still no joy.
So, my first question is - If I upgrade the Windows SDK to V7.0A, do I also need to use MFC 10 and msvcrt10, or can I stick with MFC 8?
The next question is, how do I find out which dlls are missing, and which libraries or other dlls are requesting the missing versions?

Visual C++ :: Retrieve IP Information On Any Windows
Sep 23, 2012I used to retrieve IP and NIC information by querying windows registry. Now I'm trying to use GetAdapterAddresses() API. Using GetAdapterAddresses() to get IP is not that easy, I need to dig a long deep as I check some examples so far, anyways my question is: Calling this API will return success on all versions of Windows ie: 32bits & 64bits ?
Though Microsoft has not opened any source, where this API is actually retrieving Windows IP information.?. Is it reading Registry or some windows file.
Visual C++ :: Windows 64 Bit Or 32 Bit Preprocessor Directives?
Jul 1, 2013I want to connect to an SQL Server database using ADO with VC++.
In order to do that you need to import an external dll, like so:
#import "C:Program Files (x86)Common FilesSystemadomsado15.dll"
What if the OS is not 64 bit? That would mean the (x86)-suffix would be incorrect.
how to work around this using certain preprocessor directives?
Something like this, maybe?:
#if 64bit
#import "C:Program Files (x86)Common FilesSystemadomsado15.dll"
#else
#import "C:Program FilesCommon FilesSystemadomsado15.dll"
#endif

View 2 Replies View RelatedC++ :: Call Stack Should Include All Active Sub-routines?
Feb 4, 2015I have a general question on Call Stack of Embedded uCs.
The Call Stack should include all the Active Sub-routines.
For example, in the following sequence:
Func 1 Starts -- Call Func2 --> Func 2 Starts -- Call Func3 --> Func 3 Starts --> YOU ARE HERE
The Stack should include the Return Addresses of Func 2's Body and Func 1's Body, Right?
At any certain moment (e.g. when the uC experiencing a SW Bug), Is it possible to have the uC to get all the Active Sub-Routines from the Stack and print them (e.g. for knowing it at the moment of Bug)?
It'd debug failures, when I don't work with a Debugger.
I know that Debuggers do that - i.e. show you the Call Stack at each moment - So I am wondering if I can get the uC to to it for me every time a bug occurs.

Visual C++ :: Rapidly Pasting From Clipboard Under Windows 7
Feb 3, 2013I designed an app for work that lets you enter data in a much more efficient way, then it needs to paste this data into the very curmudgeonly interface we use for work. I designed this app a long time ago while at a different company, and I used VC++ 6. I'm still using VC++ 6, but in a vbox with windows XP.
The code is being called as part of a bigger function that determines what exactly needs to be pasted into the work app spreadsheet. I have to call each item separately because the work app does not take copied tabs the way Excel would or whatever, it just ignores them. And it also pops up boxes and such that need to be handled in other ways.
The result works just fine under Windows XP, but when I do it under my regular Win7 box or on the Win7 boxes at work, it does not work properly.
This sets the data up, Text being the data to be pasted:
Code:
while (1) {
if (OpenClipboard() == FALSE) {
::Sleep(1);
continue;
}
HGLOBAL clipbuffer;
char * buffer;
EmptyClipboard();
[Code] ....
No infinite loops yet, again was just testing if it was OpenClipboard failing because it was being called again too quickly or something (and it did happen occasionally).
Then testing that the clipboard data is correct (this is always true), and pasting with keybd_event. SendInput is not available with VC++ 6.
Code:
HGLOBAL hglb;
LPTSTR lptstr;
LPTSTR buf = Text.GetBuffer(0);
while (OpenClipboard() == FALSE)
::Sleep(1);
[Code] .....
If the ::Sleeps are commented out, it will paste the wrong data almost every time under win7. It seems like it pretty much uses the last thing to be copied in the function and pastes it over and over (but not *always*). If I uncomment them, it will work as expected, but it obviously takes longer. With ::Sleep(50), it works about 80-90% of the time. Obviously I can't have the wrong data being pasted, and I'd prefer not to have to wait like this--and perhaps on a slower system or a system that is doing other things it may take longer and paste the wrong thing. It works fine on XP even without the sleeps.
Did keybd_event become a separate thread or something? Am I doing something wrong with the buffers? (I've tried using CSharedFile too with GMEM_MOVEABLE | GMEM_SHARE | GMEM_ZEROINIT settings, exact same thing.) Why does it work fine under XP but not under 7?

Visual C++ :: Windows 7 Explorer Doesn't Get Refreshed
Aug 4, 2013I have created an application to burn my data files into DVD. The problem which I am facing is as follows:
Suppose I have a folder "Doc_Files" present inside "D:Data" location for burning into DVD. The correct behaviour of the application is, after writing the "Doc_Files" folder into disc, I have to immediately delete this "Doc_Files" folder from the "D:Data" location.
I am calling the DeleteFile() Win32 API for deleting those files which are present inside "Doc_Files" folder.
The files are getting deleted successfully but they are still shown in the same folder untill I do not terminate the application.
Till the application is up those files are still visible even after they are deleted. And as soon as I kill my application and refresh my data folder those files are gone, and the folder becomes empty.
I am making use of IMAPI interfaces and methods for burning process.
Visual C++ :: Reading / Writing Registry In Windows 7?
Feb 19, 2013I have a 32-bit application that I've been maintaining for about 12 years and it runs on every Windows platform up to Windows 7. In all that time I've been using CWinApp::GetProfileXxxx() and CWinApp::WriteProfileXxxx() calls to read and write my program settings (about 70 settings) in the Registry. The settings are read from the Registry at start-up and written to the Registry when the program closes. There is also a method for the user to read and write the program settings to an INI file using the same code as the Registry access.
On my Windows 7 system the Registry read/write works just like it always has on all previous Windows versions. However, on some customer's Windows 7 machines there appears to be a problem with the Registry access. The program settings are either not being read from the Registry or are not being written to the Registry. I think the settings are not being written - but I don't know that. When the user uses the INI file the settings appear to be read and written.
The customer has complained a bit (I'd complain too) but doesn't have the time or doesn't want to take the time to run some simple tests for me to find out what's going on with his Windows 7 system.
So here is my question: Are there any user account settings or permissions that can block the program's access to the Registry? He claims he is an Administrator but I can't even get him to verify that.
Visual C++ :: Conditional Compilation Based On Whether It Is Windows 7 Or 8?
Apr 10, 2013I want to do conditional compilation based on whether it is windows 7 or windows 8. Here is the code below.
#if (_WIN32_WINNT >= 0x0602) //Condition to check whether it windows 7 or 8 .Based on this we can load msxml 3 or 6.
#import <msxml6.dll>
#else
#import <msxml3.dll>
#endif
Im building the above code in windows 8 machine.
Issue here is _WIN32_WINNT should have a value 0x0602, it means it is running in windows 8 machine.Instead it has a value 0x0601 (Means it is taking windows version as windows 7 defined in sdkddkver.h).Im not sure after installing windows 8 sdk im not able to see any include or lib files in the path below C:Program Files (x86)Microsoft SDKsWindowsv8.0A . but i can see all include and lib files of sdk version v7.0A available although i did not installed it.
Visual C++ :: Writing To HKLM Registry In Windows 7?
Jul 8, 2013When I write to the Windows 7 Registry at HKEY_LOCAL_MACHINE, I get a return code of 5 which is the "access denied" message when I execute RegCreateKeyEx.
This happens even if the User has administrator rights.
How can I tell Windows 7 to allow the program to write to the registry?
The application is a 32-bit application and it should be allowed to run in either a Windows 7 32-bit or 64-bit machine.
I noticed that when I run certain popular programs, a User Account Control dialog box comes asking:
"Do if you want to allow the following program from an unknown publisher to make changes to this computer".
Should my application call User Account Control and if so, how do I do it in C++ Visual Studio 2008?
I also found out that 64-bit Windows machines have two registry hives. Is there a different code to handle the same task?
