Hello All,
I want to make two window stick together. that is when A window moves or the size changes, B window will change it's location and size to stick to A window. when A window is active, B window will change it's z order to most top to avoid to be masked by other windows.
The first requirement is easy to meet, I just handle WM_MOVE and WM_SIZE message of A window to change position and size of B. But the z order of B window is unchanged, that is not I want.
Thanks in advance.
Hi,
I have been researching how to enable the console when a Unit Test DLL is loaded to execute a TEST_METHOD, with no success. I am using CppUnitTestFramework with Visual C++ from Visual Studio 2015 update 2.
I thought maybe posting here directly to Visual C++ experts (NOTE: it is native UNMANAGED C++ I am interested in only), maybe I could get some more useful feedback...

Hi,
Is it possible to generate a dynamic library for each architecture (armv7a, arm64, x86...) from a Dynamic Shared Library project? I currently use a command line ndk-build setup called as a pre-build step to my Xamarin project to do this, but I'd like to be able to do it all in the IDE to make debugging easier, however I can't see a way of generating a library for each architecture like I can with the NDK, short of having separate projects for each arch and referencing them all. Is that the only way to do it?
Any help would be appreciated, surely someone else has come across this issue.
Thanks,
Simon
I am using DAO with Visual C++ to access an Oracle DB via ODBC defined as a System DSN in the ODBC Data Source Administrator. My program is the sole user of the database. I am the sole user of the system. I only have one program that accesses the database. It (at least in my code) is not multi-threaded.
I am trying to update a number of fields in a record. I use the sequence of calls:
RecordSet->Edit();
For each field to be updated: Fields->GetItem( <FieldIndex> )->Value = <value>;
RecordSet->Update(DAO::dbUpdateRegular, false);
One of the fields being updated is a floating point number. Most of the time it works OK but depending on the previous value of that floating point field I sometimes get an exception on the Update() call:
"The Microsoft Access database engine stopped the process because you and another user are attempting to change the same data at the same time."
An example previous value that causes this to happen is 68.6. (There are other numbers). This happens however that previous value is put in - e.g., with a previous run of the program, or by using SQL Developer. It also happens regardless of whether the RecordSet is opened with pessimistic or optimistic locking.
The error can be cleared by using Execute SQL UPDATE statement instead of Edit() .. Update().
I know this sounds crazy. But this is 100% repeatable. If the previous value of the floating point field is one of the problem numbers - Ialways get the problem. If the previous value is NOT one of problem ones, Inever get the problem. I can run a test program multiple times putting in a selected value with no problem. As soon as I run it putting in 68.6 - the next time I run it I get the exception.
How can I diagnose the problem? Has something like this been seen before? Thanks.

Hi All,
I have a file which has been created by MFC serialization by another module. Now I am trying to read the module from a function within a COM Exe. But the Serialize function fails with the following error:
C:\Temp\File.dat contained an unexpected object.
I use the following code for deserialization:
CObListlist;
CFile in(csTempFilePath, CFile::modeRead);Anyone have idea of what is the issue here?
Hi
How to create transparent tree view like Windows Media Player?
I know ListView has a LVS_EX_TRANSPARENTBKGND and must processWM_PRINTCLIENT for it, but the tree view not has that style!
Environment: Win 10, VC++, MFC
what am I doing????
When I install the vs2015, it always gives "a setup package is either missing or damaged"R
The below program is compiling well with the VS2010 without any error ,but when i am compiling same piece of code using vs2015 getting compile time error stated that error C2248: 'Base::IDD': cannot access protected enumerator declared in class 'Base'
#include "stdafx.h"
I have read in some website that this is problem with VS2015 compiler after install update 1 but in my case i installed VS2015 and Update 3.
can any one please confirm whether this problem still persist in VS2015 update 3 pack (not able to access enum variable in the derived class)?
Hi there,
using Visual Studio 2010 SP1 and MFC I'm creating a CMFCPropertySheet with multiple CMFCPropertyPage. Since I need to use a masked input I dropped a MFC Masked edit control in my dialog template and set the following fields:
then, in my implementation of DoDataExchange:
DDX_Text(pDX, IDC_ED_MASKEDEDIT1, m_dDoubleValue);
but, as soon as I run the Property Sheet it closes automatically. I also tried to put a default masked edit but nothing to do. A breakpoint in DoDataExchange is not reached. If I delete the dropped control, and obviously any code line relative to it, everything goes well.
In another project I use the same mask and it works but it's a CDialogEx not a CMFCPropertyPage, so I'm guessing that the problem might be in there.

I want to open the default email client configured by the machine to open a mail with the fields To, Subject, Body filled and it has a zipped file as an attachment.
We are coding in a dll file using C++. This function will be invoked from Java code.
The major issue being faced is, the header file <MAPI.h> throws errors.
Referring to the solution provided here: http://stackoverflow.com/questions/4819450/launch-default-email-client-to-open-a-send-email-window-with-a-pre-selected-fi
Hi,
I'd like to add concurrency SAL annotation to my guarded static class variables, but I always get wiered error messages.
What I tried:
// declaration in .h file:
class CTrace
{
private:
static CCriticalSection m_csLogFile;
#ifdef _Interlocked_operand_
_Guarded_by_(CTrace::m_csLogFile)
#endif
static FILE * m_fpLogFile;
}
// definition in .cpp file:
CCriticalSection CTrace::m_csLogFile;
#ifdef _Interlocked_operand_
_Guarded_by_(CTrace::m_csLogFile)
#endif
FILE * CwwiTrace::m_fpLogFile = NULL;With different tries of annotations I see error messages like:
C28285 Annotation syntax error in parameter
For function 'm_fpLogFile' 'base' syntax error in 'SAL_guarded_by(CTrace::m_csLogFile)' near 'CTrace::m_csLogFile'.
C26130 Missing _Requires_lock_held_ annotation
Missing annotation _Requires_lock_held_(CTrace::m_csLogFile) or _No_competing_thread_ at function '`dynamic initializer for 'CTrace::m_fpLogFile'. Otherwise it could be a race condition. Variable 'CTrace::m_fpLogFile' should be protected by lock CTrace::m_csLogFile.
It also seems to make a difference if the static Variabel is a object, e.g. CFile instead of FILE*.
I need to use the "#ifdef _Interlocked_operand_" since I also compile on older versions not supporting SAL.
What am I doing wrong? Do you have any suggestions?
Thanks,
Christian
Hello,
My application uses IWebBrowser2 to render HTML/CSS UI. Unfortunately some anti-virus application will report security warning when it is launched. The message says "Default web browser setting is changed. Target is registry key 'HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.html\UserChoice\Hash'".
Anyone have idea how I can solve the issue?

I have build an executable(application .exe) using below code:
int main() { SetDefaultDllDirectories(LOAD_LIBRARY_SEARCH_SYSTEM32);
return 0; }
IDE Used: Visual Studio Professional 2015
On invoking this exe, I could see it looks for cryptbase.dll and bcryptprimitives.dll in the directory where executable is placed. (these are implicit system dll calls)
As cryptbase.dll and bcryptprimitives.dll are system dlls and expected to be present in system32 I do not want my executable to look for it in current directory and be vulnerable to DLL Hijack kind of attack..
On analyzing the dependency further I could see advapi32.dll is the one which is making calls to cryptbase.dll and bcryptprimitives.dll.
Though advapi32.dll loads itself from system32 directory but invokes cryptbase.dll and bcryptprimitives.dll from current directory.
If I delay load advapi32.dll the problem is resolved, but I am not sure if that is the right approach to handle this and whether this could lead to any other issues?
What is the recommended way to avoid loading of cryptbase.dll and bcryptprimitives.dll from current directory?
Dear VS doctors out there!
I am a newbie on both VS & C++. I am developing key testing programs for such as class, structure, array, function and etc.
In doing so, I have encountered handle(^), member access operator(->) and gcnew. The sample program script led to
program error c1107. Description on the possible solution is said to be related to /AI switch or LIBPATH. I read all notes
related to those keywords here in the Forum, MSDN description, and I have concluded the solution for this error to be beyond my ability, though I am reasonably good at HTML, PHP, VBA, COBOL, and MYSQL. I am at a loss. Something like this important matter deserves better explanation and sample solutions. I would appreciate that someone helps me.
Also, I owe Sera Yu big thanks for the reply I submitted the question for last June. Then, I did not know how to get back to the person who tried to help me. My sincere apology to Sera Yu.

Hello,
I'm working with a Visual Studio 2015 C++ program converted from a VS 6.0 C++ program.
When I run the program it gives this error:
Exception thrown at 0x771AB2D5 (ntdll.dll) in Magic.exe: 0xC0000005: Access violation reading location 0x06FFFFFF. If there is a handler for this exception, the program may be safely continued.
I use the debugger to find out where it is blowing up. It is stopping inside this for loop that is highlighted here:

}
If I stop it just before it blows up, "m_pData" contains: "m_aCnd = 0x0162637c {{m_nField=0 '\0' m_nOperation=13 '\r' m_sText=<Error reading characters of string.> ...}, ...}m_sMailBox = <Error reading characters of string.>"
which does not seem readable.
It looks like m_pData is initialized earlier in the method with this line:
m_pData = (TYPE*) new BYTE[(size_t)nAllocSize * sizeof(TYPE)];
Any help that anyone can provide to help resolve this error would be gratefully appreciated.
Thanks,
