I'm building the Windows version of a cross-platform app. It was originally written for gcc (i.e. mingw, on Windows) but in my case I'm building with MSVC. One of the source modules has this line:-

Code:

---

setlocale (LC_MESSAGES, NULL);

---

The above line crashes if I build with MSVC. I guess that's not surprising because MSVC doesn't have any support for LC_MESSAGES.

But... what is it that doesn't support LC_MESSAGES? Is it MSVC - or does Windows itself not support LC_MESSAGES? I'm only asking because the same code built with mingw doesn't crash. Is that a happy accident? Or does mingw somehow manage to support this on Windows when MSVC can't??

Hi guys, I'm learning C++, but I have no idea about how to write this program.

"Write a program to read in a filename via stdin and write a C++ source template to it. Ensure that the generated file compiles and runs. Such a template would have at least a #include directive and an empty main function, ready to be filled. Once you have written this program, you may use it to jumpstart your work on other programs. "

Please help. Thanks

Hello all,

I have recently began learning C++. My programming experience is limited mainly to the old VB, VB6 and a bit of experience with VB.NET... I started programming in high school back in 1980 using a PDP11 time sharing system... Those were the days...

I am still very new to the *new* Visual Studio versions, C and C++. I have always wanted to learn C, I started doing that awhile ago but got sidetracked. So far the task seems daunting but I am moving along slow and steady...

I want to build an app where performance is key, using (I think) VCPP. From what I gather, CLR and the .NET framework is not the ideal choice if speed is key. So I am trying to figure out how to use just native C++, or whatever is the fastest possible route.

I am using Visual Studio 2010, I am very familiar with the Visual IDE from my VB6 days and thought that I could start my project by choosing a "windows forms project"... But as I begin and look at the control toolbox I see a tooltip telling me that these controls are .NET controls, which makes me wonder exactly what I'm getting into starting out like this.

Any suggestions are much appreciated.

Hi,

Im new to c++ and I was wondering if someone can help me.

I would like to disable the printscreen key inside a game.

I run a small online game server and if a player uses printscreen key rapidly

he can blink something like using a cheat engine to run faster.

I would like to have a code to work in visual studio > compile > hook to my .exe

I dont know if it is the right way to stop printscreen key in game.

Thank you.

Hi everyone,

In my research I want to hook (intercept) the method (virtual tables hook) "ExecQuery" of "IWbemServices" interface(COM objects)
and I use Application Verifier (note: important only for injection in this thread) to inject a dll in the beginning of a specific process.

We can assume that the above process is using com objects and will use "ExecQuery" method during its execution, ("CoCreateInstance" and "ConnectServer" too.).

I want the dll to hook "ExecQuery" after injection. (ofcourse I waited till ole32.dll and fastprox.dll were loaded).
From my knowledge I know I need to create a com instance, and use it to query "IWbemServices" interface.
After I get the interface I can hook the virtual table of it.

Code copy of the process to execute:

Code:

---

wchar_t comName[MAX_PATH]=L"test";
        DWORD dComputer = MAX_PATH;
        WCHAR temp[MAX_PATH];// = L"ProcessorNameString";
        //LPSTARTUPINFOW stinfo=NULL;

        char lzValue[255];
        HKEY hKey;
        LONG returnStatus;
        DWORD dwType = REG_SZ;
        DWORD dwSize = 255;
        unsigned int i = 1000;
        HRESULT hres;
        IEnumWbemClassObject* pEnumerator;
        IWbemServices *pSvc=NULL;
        IWbemLocator *pLoc = NULL;


        hres = CoInitializeEx(0, COINIT_MULTITHREADED);
        hres = CoInitializeSecurity(
                NULL,
                -1,                          // COM authentication
                NULL,                        // Authentication services

                EOAC_NONE,                  // Additional capabilities
                NULL                        // Reserved
                );

        unsigned int te2 = GetLastError();
        printf("%d\n",te2);
        hres = CoCreateInstance(
                CLSID_WbemLocator,
                0,
                CLSCTX_INPROC_SERVER,
                IID_IWbemLocator, (LPVOID *)&pLoc);

        te2 = GetLastError();
        printf("%d\n", te2);
        hres = pLoc->ConnectServer(
                L"ROOT\\CIMV2", // Object path of WMI namespace
                NULL,                    // User name. NULL = current user
                NULL,                    // User password. NULL = current
                0,                      // Locale. NULL indicates current
                NULL,                    // Security flags.
                0,                      // Authority (for example, Kerberos)
                0,                      // Context object
                &pSvc                    // pointer to IWbemServices proxy
                );
        te2 = GetLastError();
        printf("%d\n", te2);
        hres = pSvc->ExecQuery(L"WQL", L"SELECT * from Win32_Processor", WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, NULL, &pEnumerator);

        // remove protection from the vtable
        DWORD dwOld = 0;
        if (!::VirtualProtect(*(PVOID**)(originalInterface), sizeof(LONG_PTR), PAGE_EXECUTE_READWRITE, &dwOld))
                return E_FAIL;

        // hook interface methods
        g_Context.reset(new Context);
        HookMethod(originalInterface, (PVOID)Hook::ExecQuery, &g_Context->m_OriginalExecQuery, 20);

        return S_OK;
}

---

The COM functions used in MAIN(above process) are working.


I get an E_FAIL from
"hres2 = CoCreateInstance(
CLSID_WbemLocator,
0,
CLSCTX_INPROC_SERVER,
IID_IWbemLocator, (LPVOID *)&pLoc2);"
code in dll function.

and IWbemLocator and IWbemServices stay NULL.

any suggestions?

A working code sample will be good also.

How can I convert the strings to integers?

Hello, everybody can y'all be so kind to help me with my program? I am trying to convert strings to integers. This is my task:
Open a file "numbers.txt"
read integer numbers as strings from the file (one number per line)
convert each string to a numeric representation (without using stoi() or similar functions from the string library)
store converted numbers in an array
close "numbers.txt"

So far I have read integer numbers as strings but cannot convert the string array to integers without using the string library. Can someone help? My code won't compile but I am trying to do this: 154: Sum = 4*1 + 5*10 + 1*100 = 154 so it can convert to an integer.
This is what I have so far:

Code:

---

#include <fstream>
#include <string>
#include <sstream>
#include <iostream>
using namespace std;

int StringToInteger( string arraySize);

int main()
{
  ifstream infile;
  infile.open("numbers.txt");
  const int size = 1000;
  string myArray[size];
  int i = 0;
  while (infile >> myArray[i])
  {

      cout << "The string is \"" << myArray[i] << "\"" << endl;

      myArray[i].size();
      cout << i << endl;
     
      StringToInteger(i);
      ++i;

     
  }
}

int StringToInteger( string arraySize)
{
  int values = 0;
  for (int index = 0; index < arraySize.size; index++) {
      values *= 10;
      values += (arraySize[index] - '0');
  }
  return values;
}

GetActiveObject() returns "Operation Unavailable" (0x800401e3) when Excel is running

In Windows 7, I’m trying to control Excel 2013 with OLE Automation. It works fine if Excel hasn’t already started up. I’m attempting to use GetActiveObject() to tell if it has started up, but I always get the same error: “Operation unavailable” or 0x800401e3. I get the error whether Excel is running or not. Unfortunately, if Excel is running, then the code ends up starting a new instance of Excel using CreateDispatch() which is NOT what I want to do. This is old code, and has worked with Excel for many years, although perhaps not Excel 2013.

Code:

---

        if( !m_XLApp.m_lpDispatch )
        {
                try
                {
                        LPDISPATCH pXLAppDispatch = NULL;
                        LPUNKNOWN lpUnk; CLSID clsid;
                        if( S_OK == ::CLSIDFromProgID(L"Excel.Application", &clsid) )
                        {
                                if( S_OK == ::GetActiveObject(clsid, NULL, &lpUnk) )  //always fails
                                {
                                        VERIFY(lpUnk->QueryInterface(IID_IDispatch, (void**)&pXLAppDispatch) == S_OK);
                                        m_XLApp.AttachDispatch( pXLAppDispatch );
                                        lpUnk->Release();
                                }
                        }
                        if( !pXLAppDispatch )
                                m_XLApp.CreateDispatch( _T("Excel.Application") );

but I tried the code with no success. Excel may have lost focus long before I run my program and GetActiveObject() still fails. How do I get it too succeed when Excel is running?

Thanks,
Gary

Hi, ALL,
Does anybody have an old MFC source code?
I am looking for a font property page source.

I currently have MSVC 2010 Pro, but I don't see this source code unfortunately.

Thank you in advance.

Hello all & Thanks for reading this,

-I would have a question on you:
-I have created a small application on MFC/C++ that draw different geometric shapes on screen using the mouse (like Paint). These shapes can be moved and rotated,
so, I had to keep all these created shapes in a vector and draw all of them in OnDraw().
-My problem is, when I create many shapes (more than 50-60) and I try to move/rotate one of the shapes, these movements/rotations become very-very slow.
-Could you give me some tips in order to make my application faster when moving/rotating those shapes?

Code:

---

OnDraw(CDC* pDC)
{

    for (int i = 0; i < numberObjects; i++)
        objects[i]->DrawShape(pDC);
}

---

Many thanks!

We have a commercial video editor written in MFC/C++. We want to do some custom stuff with the Save dialog that simply isn't possible with the new IFileDialog built in to Windows Vista+ and the old XP style dialog just doesn't look right when used in modern OSes.

Does anyone know of a 3rd party Save dialog that offers better customization while retaining the look/feel of the modern IFileDialog? Can be commercial or open source. I just don't want to have to resort to writing my own from scratch if I don't have to.

The main feature we need is the ability to filter/group the file types list after the dialog is displayed. Our product uses a user customizable profile system for saving and the list can get unwieldy. We want some way to organize or filter the list to make it easier to use, but the existing IFileDialog does not allow you to change the file types list at all after it's displayed.

If anyone knows of a dialog that will work for this purpose please let me know. Even if it's a commercial product we have to pay for it's fine.

Windows 10 - Size of Radio Buttons and Checkboxes

Hi

We have a UI where a customer have reported problem when running on Windows 10. On W10 the radio buttons and checkboxes are bigger than "normal" (compared to when they used W7), which give the result that the text is cut off. Even the caption bar is increased in size.

When we test the UI in our environment, we haven't seen this behaviour. I suppose that this must be due to some kind of setting, but haven't found out where to change.

Can anyone give me a hint of where to change / which setting.

Regards

Once the secondary shell is decoupled from the master one,
I need to write an emulated theme service.
How can I write a emulated theme service easily?
What I really want to do instead is to use the original service (I need
to duplicate it since that windows service is a single instanced service)
It is not that easy to do since when I change the theme, the cache is changed,
so subsequent call to OpenThemeData would retrieve the most recent theme.

Then I thought about giving a pass-thru hand-over call.
For example

Code:

---

void HookedOpenThemeData(...)
{
    // call the original service   
}

---

But you see, it is very difficult, when I call the original service from a hooked function,
it will always return the same theme no matter what....

And the theme service is started when the system is booted strapped.
And it is a single-instanced service.

Therefore, I must write an emulated service of that kind.....
But is it possible to create a pass-thru instead?
Thanks
Jack

We have one legacy Control Panel App (.cpl) that use for registry and configuration file modification. Previously it was compiled on Visual Studio 2008 and used on Server 2012 & Windows 7. We have to run as Administrator to save changes.

I have recently migrated this app to Visual Studio 2015 and when run as Administrator nothing happens (no error, nothing logged in events log)


On Windows 7:
UAC Enabled:
1) User can run application
2) Nothing happens when application run as administrator


UAC Disabled:
1) User can run application
2)User can run application as administrator


On Windows Server 2012
UAC Enabled:
1) User can run application
2) Nothing happens when application run as administrator

UAC Disabled:
1)User can run application
2)Nothing happens when application run as administrator

I have try using Windows Performance Recorder tool but I am not able to find anything about this control panel app.

Can someone point me to right direction how I can resolve this issue?

I have a Windows application in Delphi 5.

I have two monitors. When my application runs, the parent is displayed on the first monitor. When I move the parent window to the second monitor and click a button, this child window stays on the first monitor. Is there a way to make the child window stay with the parent window no matter where the parent window is located? I searched related to this but solution is in C# not in Delphi, I am very new in Delphi. Child forms are creating at run time.

My Code is:

Code:

---

function BeforeCreateForm(Session:ISmSession;var IsDLL: Boolean):HWND;
var
  SmGUIServices: ISmGUIServices;
  MainWindowHandle:HWND;
begin
  MainWindowHandle:=0;
  IsDLL := false;
  if (Application.Handle = 0) and (Session <> nil) then
  begin
    IsDLL := true;
    SmGUIServices := (Session.Services.Item[TDM_SmarTeamServices[srvSmGUIService]] as ISmGUIServices);
    if SmGUIServices <> nil then
    {$IFNDEF BUILTPACKAGE}
      MainWindowHandle:=ForceIntegerToHwnd(SmGUIServices.MainWindowHandle);
    {$ENDIF}
  end;
  result:=MainWindowHandle;
end { of BeforeCreateForm } ;

procedure TSmForm.AfterCreateForm(Session:ISmSession; SmHelpContext:TDM_Int32; IsDLL: boolean);
begin

  if SmSession<>Session then
    SmSession:= Session;
  if SmHelpContext > 0 then
    HelpContext:=SmHelpContext;

  if (IsDLL) then
  begin
    if (Icon.Empty) and (ParentHWND <> 0) then
      SendMessage(Handle, WM_SETICON, 1, SendMessage(ParentHWND, WM_GETICON, 1, 0));
  end;
end { of TSmForm.AfterCreateForm } ;


constructor TSmForm.Create(AOwner: TComponent;Session:ISmSession;SmHelpContext:TDM_Int32);
var
  IsDLL: Boolean;
begin
  ParentHWND:=BeforeCreateForm(Session, IsDLL);
  HelpContext := 0;
  SmSession:= Session;
  inherited Create(AOwner);
  AfterCreateForm(Session,SmHelpContext, IsDLL);
end;



procedure TSmForm.CreateParams(var Params: TCreateParams);

var
  SmGuiServices: ISmGuiServices;
  MDIChild : TIMDIChildForm;
  MultiTabType :TDM_Int16;
  I:Integer;

begin
  inherited CreateParams(Params);
  if ParentHWND <> 0 then
  begin
    Params.WndParent:=ParentHWND;

    SmGUIServices := (SmSession.Services.Item[TDM_SmarTeamServices[srvSmGUIService]] as ISmGUIServices);
    for I := SmGUIServices.SmViewWindows.Count - 1 downto 0 do
    begin
      if(SmGUIServices.SmViewWindows.item[I].SmView<>nil) then 
      if(SmGUIServices.SmViewWindows.item[I].SmView.ViewType <> vwtBomView) then     
      begin                                                                           
      MDIChild := TIMDIChildForm((SmGUIServices.SmViewWindows.item[I] as ISmRawViewWindow).SmViewWindowHandle);

      MultiTabType:=GetMultiTabType( MDIChild.tabSmView, MDIChild.tabSmView.ActivePage.PageIndex);

        if UpperCase(SmSession.ApplicationName) = 'MYAPP' then
        (MDIChild.MDIViewer.ViewerType = 10))) then 

        begin

        // Params.ExStyle := Params.ExStyle or WS_EX_TOPMOST;
          Params.ExStyle := Params.ExStyle or WS_EX_APPWINDOW;
        Params.WndParent := GetDesktopWindow;


          exit;
        end

        else
        begin
          if (MultiTabType = MT_Viewer) then
          begin
            Params.ExStyle := Params.ExStyle or WS_EX_TOPMOST;
            exit;
          end;
        end;

      end;
