Visual C++ :: Enable Virtualization In 64bit Mfc App?
Dec 5, 2012
I have a version of an app in 64bit but the problem is under program files on windows 8 64bit it doesn't have access to the programs files folder... usually virtualization will redirect it to the virtual store but with 64bit exe's this doesn't happen automatically. How do I enable it in code or in the manifest file?
From MSDN:
Virtualization is only enabled for:
32 bit interactive processes
Administrator writeable file/folder and registry keys
Virtualization is disabled for:
64 bit processes
Non-interactive processes
Processes that impersonate
Kernel mode callers
Executables that have a requestedExecutionLevel

I have two third party DLL files that I wanted to check if they are 32bit or 64. I searched the web and some suggested corflags, I found it under "C:Program Files (x86)Microsoft SDKsWindowsv7.0ABin" (my machine is 64bit but I didn't find the utility under "Program Files" folder), it came out with the message:
corflags : error CF007 : The specified file does not have a valid NT file header
Whats wrong with it?

#define DWORD ?
How to I write this statement?
In my program, the DWORDs are treated as unsigned long, so that They are 64-bit "DWORDs" instead of 32-bit ones...

I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
Code:
void CDummyView::OnUpdateMenuItem1(CCmdUI* pCmdUI)
{
if(m_bShowMenuItem1) {
pCmdUI->Enable(TRUE);

i have tried to search on the Internet but haven't found a suitable result that links in with what I want to do, that is to creation a WPF application and when you press a enable button it will enable the LAN and when I click the disable button it will disable the LAN until i click the enable button again. Now I know how to creation a WPF and the buttons, but how would I do the disabling LAN and enabling LAN?
By LAN i mean just the networking adapters, so that the PC cannot connect to a router and then the Internet.

I have ploughed through the exchanges in all the forums, yet I still cannot make it work. The following is a tiny Code::Blocks program, written to isolate the problem:
// resource.h
#define IDR_MYMENU101
#define ID_FILE 102
#define ID_DISABLE103
#define ID_ENABLE 104
#define ID_MESSAGE105
#define ID_EXIT106
[code].....
case ID_ENABLE is similar to case ID_DISABLE above, and neither works. case ID_MESSAGE and case ID_EXIT both works as expected.I have tinkered with EnableMenuItem(), but without success.

template <typename FIRST, typename... REST, typename std::enable_if<std::is_convertible<FIRST, Base*>::value>::type* = nullptr>
void foo (FIRST first, REST... rest) {}
that successfully allows me to enable the function foo() only if FIRST is convertible to Base*, but I also only want foo() enabled if each type in REST... meets the same condition. What is the syntax for that? If no such syntax exists, how to achieve that effect?

Arrays are by far the most fun to work with and I really need see if its possible to enable an array to count apples, pears, peaches, from a group of three each.
If any of the fruit groups were chosen how might an algorithm be put together to count how many were chosen from each group. But lets take into consideration that these fruit groups are not supposed to be randomly generated, instead they belong as an array with certain amount of chosen occurrences. To show how many fruits were chosen from each group example, 1 from group 1, 2 from group 2, 3 from group 3 the out put is the important part because it shows the group and the occurrence of that group. the algorithm should be able to display the group with an occurrence as well

The example enable a client to iterate the internal std::vector using being() and end().
Code:
class foo {
public:
typedef std::vector<std::string>const_iterator iter;
iter begin () const;
iter end () const;
[Code] .....
In the future I see the need for this class to be able to control sequence (sorting) and also show a subset of the complete list based on a search parameter.
Using std::sort appear to solve the ability to sort the collection.
How can I return an iterator to the client which only iterates a sub-set of all items in the std::vector?
An example would be, I add this method to the class;
Code:
void find(const std::string& st);
So if the client performs (below) only items in std::vector that contains the character "a" should be possible to iterate.
Code:
foo f;
f.search("a");
One option would be to operate with two collection inside the foo class. One more static containing all items and the other containing the sorted and filtered items. This would lead to some copying but should work. Far from perfect.

Using C . I have been tasked (for a University assignment) to create a program that will enable a user to upload an image and convert that image into ASCII text using SDL on a Linux system. I've managed to open a window, display an image (non-selected) and convert it into grayscale using
case SDLK_g:
for (int y = 0; y < image->h; y++) {
for (int x = 0; x < image->w; x++) {
Uint32 pixel = pixels[y * image->w + x];
Uint8 r = pixel >> 16 & 0xFF;
Uint8 g = pixel >> 8 & 0xFF;
Uint8 b = pixel & 0xFF;
Uint8 v = (0.212671*r)+(0.715160*g)+(0.072169*B)/>;
pixel = (0xFF << 24) | (v << 16) | (v << 8) | v;
pixels[y * image->w + x] = pixel;
I am absolutely clueless as to how I can get the user to upload an image to the program and then begin the image -> ASCII conversion. I've found seem to be written in C++ or C# to make the conversion I should be using the GetPixelColour command?

The project is about reading data from PIC and display the data on the dialogue created by the MFC GUI of Visual studio 2010. There are 4 data need to be displayed (2 weight and 2 angle). the data will be display on the edit control box on the dialogue.
I have try to solve the COMPort and Readdata issues many times, but I'm fail. I have read many sources and implement the source codes... They are never work....
The detail about the issues that I need to solve is clearly mentioned on the main dialogue.cpp. Take a look to an uploaded zip file that I have attached.

What I'm trying to do is get the selected folder value put into my dirlocation var.
Code:
private void dirLocation_Click(object sender, EventArgs e) {
FolderBrowserDialog fdb = new FolderBrowserDialog();
fdb.Description ="Please choose the directory your .rlt files are located in";
if (fdb.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
dirLocation = fdb.SelectedPath;
}
Is this how you do it? I keep getting an error like Cannot implicitly convert type 'type' to 'type.

I heard that you can't use it with express, but that doesn't seem right... Can you use it with Codeblocks, at least? I just hate the Qt Creator IDE. I don't like the UI... all I want to do is code Qt. I don't care much for the GUI editors.

I don`t known how to convert IP to hex .
In this link [URL] .... . I see hex IP : Hex IP 0x462a1779
I want to convert IP "70.42.23.121" to "0x462a1779"
Code:
#include <winsock.h>
#include <windows.h>
#include <stdio.h>
UINT32 ip_to_hex(UINT32 ip_add) {
UINT32 ip_hex;
//code convert ip to hex
return ip_hex;
[Code[ ....
And this is result : 7b 1e 80 and a , not 0a
Further i think we must separate each octect by a (dot) . , Then convert decimal to hex.

In a C++ project, I need to call a C# created COM object (as a .dll)
Is there a way to use such a COM object without having it be registered in the registry?
The C# COM dll is just a "go between" our C++ code and a .NET library, there's no "COM contract" of any kind, the COM interfaces change each version. The fact it's COM and needs registration is annoying because it makes it hard to have multiple versions of our software installed (needed under some circumstances) and running at the same time.
I'd like a way to not have any registration at all. And just be able to do a LoadLibrary("c:TheRightPathcom.dll") of the right dll and then get going from there.

I have a C++ app that uses OpenCV. Currently i am statically linking the OpenCV libs into my app. This is adding an extra overhead of 6+ MB.
i would like to remove some of the features that i am not using in OpenCV. The features am using are,
Capture frames from Webcam.
Face detection.
Image formats (JPEG, PNG).
Image rotation & resizing.
Is it possible to remove other features and trim down the libs?
My C++ app is developed in Visual Studio 2012.

Is there any chance to use CSplitButton in VC6 ?
I had tried to use something appropriate founded on CP, but they are using DrawItem, and I had problems with windows style, and I had tried to make myself one, overriding OnPaint, but I front with flickering (I put the sample below)... so, I wonder if I could get (from somewhere) CSplitButton and add to my project ... if you say that I could, can you provide me the CSplitButton source code ? I mean, only .cpp implementation file ...

I have an assignment where I need to go through all the files in a folder. For each file I need to know each unique file extension, how many files for each unique file extension, and the total size for each unique file extension. I have to be able to sort through this using either the file extension or the total size of the file extension. The first thing I thought of using was a map. This will keep track of each unique file extension and the amount of times that file extension was found. How do I now associate the total size of the file extension to my map? So for example I need the output to be something like this:
Using file extension for sort
.cpp : 1 : 3400
.exe : 3 : 3455600
.mp4 : 25 : 200000404
Using total file extension size for sort
.mp4 : 25 : 200000404
.exe : 3 : 3455600
.cpp : 1 : 3400
Here is the code I have so far:
Code:
#include <iostream>
#include <filesystem>
#include <map>
[Code]...
I was thinking of somehow using a class to implement this, but don't know how to go about doing that. A

I got a program from somebody. He had its initialization to run his program but never bothered to save the data for later use. Now I wanted to add the New, Open, Save, and Close to it, so I add OnNewDocument ahead of his program. It crashed every time I ran it.
Shall I include his initialization in the OnNewDocument? If I can not separate the initialization part from his code, e.g., they come in as dll, what shall do?

Is it possible to create an app that can be saved on my desktop that can be used with an excel file that is saved on my desktop? I have opened VS 2010 and I have created a form design that has a button for every sheet name in my excel file. All of the sheet names are hidden with the exception of one. When a button is pressed on the c# form, I would like for that sheet to be shown in excel. Then once the updates have been made to that sheet in excel, I want a button to be at the top of the excel worksheet that will hide that worksheet again and return to the form c# form...can that be done?
