Visual C++ :: Add USB Plug And Play Feature Inside DLL
Nov 5, 2013I have designed a vc++ dll for a controller. I want to add usb plug and play feature inside the dll. I searched on line and came to know:
"If the project is an unmanaged C++ DLL project, then I can only create windows in an unmanaged way, i.e. the usual Win32 API way, such as adding a new dialog box as a resource, or simply using RegisterClassEx() and CreateWindowEx() to create the window yourself, then pump messages for those windows using GetMessage(), TranslateMessage() and DispatchMessage()."
how to use this concept.
I have created a separate application (in delphi 2007) that load this Dll. But I want to add this Plug and Play feature inside me dll.
Visual C++ :: Blocking Keyboard Play / Pause Button In Windows 8?
Mar 27, 2014I am writing an application that needs to temporarily disable the Play/Pause button that appears on multimedia keyboards.
Normally, a key can be blocked quite easily by installing a low level keyboard hook (WH_KEYBOARD_LL) where the KeyboardProc intercepts the key (in this case VK_MEDIA_PLAY_PAUSE) and returns a "1" instead of calling CallNextHookEx. I have tried this with other keys (including the Windows key VK_LWIN) and this works perfectly. I also have no problems with this method under Windows 7 where all keys, including VK_MEDIA_PLAY_PAUSE get blocked.
Windows 8 is a different story. When my application has input focus, everything works as expected, meaning the VK_MEDIA_PLAY_PAUSE key gets blocked and no other application responds to it. However, when my application loses focus, my hook procedure gets called (this was verified by sending out a OutputDebugString) but other applications respond to key even though I return a "1". As soon as my app gets focus again, everything is block as it should.
After some investigation, I found that the multimedia keys not only generate keystrokes but also generate WM_APPCOMMAND messages so I added ShellProc (WH_SHELL) hook with the following hook procedure:
LRESULT __declspec(dllexport)__stdcall CALLBACK ShellProc(int nCode,WPARAM wParam,LPARAM lParam) {
// Do we have to handle this message?
if (nCode == HSHELL_APPCOMMAND) {
OutputDebugStringX(">>>>> HSHELL_APPCOMMAND");
[code]....
This procedure is only getting called when my app has input focus. Whenever I have input focus and return "1" the Play/Pause command gets blocked. As soon as I lose focus the procedure does not get called/hooked.
As I have mentioned, the code works for other keys, just not the multimedia keys.
Alternatively, another way of blocking the multimedia keyboards Play/Pause button?
C# :: Unable To Get All YouTube Results (API 2.0)
Nov 5, 2014I'm using below code snippet to fetch Youtube video titles, when you enter a query into a listbox, and press the search button:
int resultsn = 0;
void YTReq(string appname)
{
devkey = "my-dev-key-here";
YouTubeRequestSettings settings = new YouTubeRequestSettings(appname, devkey);
request = new YouTubeRequest(settings);
[code].....
But what i get is exactly 500 results, even if i remove the 500 search limit radio-button (i've put that later, after seeing that the search only fetches 500 results). But when i search the same query on YT, i get 1000s of results. What's the wrong with my code?

Visual C++ :: How To Pass CStringArray From Application To DLL
Feb 11, 2013I passed the CStringArray to dll & wrote the String in a file.

Visual C++ :: Replacing GUI In Win32 Application?
May 15, 2014I have a Win32 C++ application which works pretty well, but I don't like the GUI and I want to replace it with one designed graphically, a la Windows Forms. What is the best strategy to port my code? I tried creating a new Windows Forms C++ application and got pretty far with it, but was stymied when trying to call my unmanaged functions on a button press. If I can't use Forms to add a GUI without completely rewriting the program, what's my best bet?

Jan 16, 2013In a typical MFC application I use SetRegistryKey(_T("My_Company")); to set the root registry entry for my application. The MFC application however creates an entry by the name of executable where it stores all the settings of that application. I don't want that because we often change the name of executable and I want it read registry from the same set location. As example if my application name is Calculator.exe and Calculator_debug.exe it creates two different registry settings.
My_CompanyCalculatorsettings
My_CompanyCalculator_debugsettings.
How can I stop that?
Visual C++ :: MDI Application Client Window
Apr 17, 2015I am developing a MDI application that will contain a RibbonBar and a Properties Pane window. The MDI documents are not tabbed. I am finding that when I try to move the client window around, it gets clipped by the RibbonBar and the Properties Pane window (shown in image). I know the client window cannot go outside the client area, but can the client window be on top of the ribbon bar and the properties pane window?

Nov 11, 2014I'm struggling with the pan gesture in a desktop application for my Surface Pro 2.
I simply want to pan (or "swipe" if you prefer) with two fingers, but it doesn't behave like I want it to. If I put two fingers on the screen and move them straight diagonally, I receive a series of client coordinates that are aligned in a vertical or horizontal direction. Only if I perform some circular motion, then it's suddenly possible to move diagonally and receive coordinates accordingly.
I've tried with MFC, by overriding CView::OnGesturePan. I've also tried with a sample project provided by Intel, that handles the GID_PAN message in WndProc to move a rectangle around, but with the very same result. The project can be downloaded from [URL] ... fordesktop.zip, so you can quickly reproduce the behaviour if you have a touch screen.
Code:
void GestureHandler::handlePan(HWND hWnd, GESTUREINFO gi) {
if (gi.dwFlags & GF_BEGIN) {
m_first.x = gi.ptsLocation.x;
m_first.y = gi.ptsLocation.y;
[Code] .....
I first thought it had to do with the points being too close to each other. I mean, if two points lies only one pixel apart, it can only result in eight different directions. But if I modify the code to only update "m_first" when the distance between the points are greater than some minimum distance, the points still keep being projected to a horizontal or vertical line relative to the first starting point.

Visual C++ :: String Passing Between Functions In SDI Application?
Apr 8, 2013I am doing an project in SDI. I have two functions name sendtext(CString str) and displaytext(CString inr) both in different class. I have a pointer name pView to send the string str to function "displaytext". The problem is after some operations i get a text in str and i send that text to display text in the output screen i get the text and wen the second text comes to "displaytext" the former text disappears and the latest string only present. How can i display both the text in the output window on ClistCtrl class.
Code:
Void sendtext(CString str)
{
// do some operations
................
pView->displaytext(str);
}
void displaytext(CString inr) {
CListCtrl &ctlsde = this->GetListCtrl();
ctlsde.InsertColumn(1, _T("First "), LVCFMT_LEFT, 80);
int nItem;
nItem = ctlsde.InsertItem(0, inr);
}
Visual C++ :: Exiting Application During While Loop Operation
Jun 16, 2013I have a VC++ 6 dialog-based application. This application is intended for reading data from a USB device (this is a FTDI FT245R chip). I have a start button on the dialog. On clicking it, unsigned char data retrieved from the USB device is displayed on the dialog. The start button invokes a function which includes a while (1) loop inside which the USB device is read and the values displayed.
There are no break or continue statements inside the always operating while (1) loop. All this works fine. My problem is how do I exit the application as normally it would just run forever? I have put an exit button on the dialog with code added to call OnOK(). Normally this would nicely close the application but as I have an endless while loop in my application so this button doesn't seem to work. Nothing happens on clicking it and clicking it repeatedly just hangs the program.
Visual C++ :: Application Won't Start Once Installed On Other Computers
Sep 13, 2012I use standard libraries and INNO Setup, wich is a free setup file creator.
I succeeded in adding NetFrameWork 4.5 installer into the setup (it runs it after installation, and before running my software (named GOFINDER).
Now, i remember that this happened to me, but after three months of programming, mine used to start and still does. But I know it sometimes doesn't start, and I don't know why exactly.
I checked to make sure that I needed only FrameWork 4.5.
But maybe it is because of Visual C++ Runtime wich is not added upon setup.
I will try to check this after posting cause this has just popped up in my mind.
I'm asking you how can I Make sure, that distributing my software won't do that anymore.
Is it because my application file is not set on Run as Administrator?
Cause normally, it opens without this necesity, except as a Shell (well I have to check back but I think it does if I check on the run as administrator checkbox.
The problem is not really with InnoSetup, but I also would like to know how I can check that box automatically upon setup.
they say they have a documentation but I don't find it on my computer.
And... why would it start on my computer, and not on my beta-testers's one?
Visual C++ :: Converting Code To CLI Form Application?
Jun 10, 2013As a starter project I want convert a Neural net app from "AI Techniques for Game Programming (2002 Buckland)" to a Visual C++ CLI Forms application. I have created the interface and now I have to rewrite the in/output routines, amongst other things.
First question I have has to do with variable initialization used by Buckland. Code looks like this:
Excerpt from header file (CNeuralNet.h):
//-------------------------------------------------------------------
//define neuron struct
//-------------------------------------------------------------------
struct SNeuron
{
//the number of inputs into the neuron
int m_NumInputs;
//the weights for each input
vector<double>m_vecWeight;
[code]....
Question I have: what is the the function of ": m_NumInputs(NumInputs+1)" after the method declaration? Buckland does this in many places in his code. In this case it's a struct, but he does it with classes too.

Oct 11, 2013I'm trying to write a program that passes Windows messages back and forth from another program that controls a laboratory instrument. I was able to write a program that successfully passes instructions, as evidenced by the instrument doing what I tell it. However, I am having trouble getting a return status from the instrument. The manual instructs the following:
// demo code, etc.
// send message to the instrument operating software here...
SendMessage(hwnd, WM_COPYDATA, tag, (LPARAM) &cd)
Either a completion message or return data is returned. Remote commands ReturnStatus, ReturnTiming, and ReturnData return data. In either case, data is received through an asynchronous windows message inside Win32 COPYDATASTRUCT type data packet.For example, a typical OnCopyData window callback is shown below, where the string data retrieved is finally stored into a Microsoft CString object. Note the use of variable replyTag, discussed above, which is used to isolate the correct windows message returned.
BOOL CUserDlg::OnCopyData(CWnd* pWnd, COPYDATASTRUCT* cd) {
….
if (cd->dwData == replyTag) {
/* String pointing to status */
CString retStatus = (char*) cd->lpData;
}
….
}
I can't tell if my problem is in generating the replyTag, getting the HWND to my own console window, or the actual receiving part of the code.
When setting the replyTag, the manual instructs: UINT replyTag = RegisterWindowMessage(“SOFTMaxProReplyMsg”);. However, I have to put an "L" in front of the string or I get a data type error (can't convert const char* to LPCWSTR).
When setting a HWND for myself, the manual instructs: HWND MyWnd = GetSafeHwnd().
That produces an error because GetSafeHwnd is a function of the Cwnd class, and I don't have a Cwnd. I have replaced it with HWND MyWnd = GetConsoleWindow();
When listening for the reply message, the manual instructs what I quoted above. However, I again don't have a Cwnd. I therefore simply used
if (cd.dwData == replyTag) {
CString retStatus = (char*) cd.lpData;
}
The above if statement always evaluates false, and the cd.lpdata contains the message that I had sent out instead of a reply message. How to get a reply using my console application. Here is the full code of my function:
Code:
#include "stdafx.h"
#include<iostream>
#include<vector>
#include<string>
#include<afxwin.h>
using namespace std;
void SendCommand(string command) {
// Get tags to identify the receiving and sending messages
