I want to make a program which can run in another program. My program have structures flowing:
while (1) {
check (keypressed);
{
do something;
}
}
But check(keypressed) function only active in my program, It can't run in another program.
I am trying to run an OpenCV program from command line, but it gave error like "The program can`t start because opencv_220d.dll is missing from your computer." Try reinstalling the program to fix this problem. I am using Windows 7 & Microsoft VC++ 2010. How can I run the program?

i created a windows service that will run another program. but the program i want to run has a gui and i don't want the gui to be visible, i just want the program to run in the background.
But i have to do it without editing the gui program
here's my code:

I am currently working on problem set 4 for Harvard's online CS50 course. I am working on a program that resizes a bmp image by a factor of N. N in entered along with an in-file and out-file in a command line argument. The program needs to calculate the header file for the out-file and write it to the out-file. It then needs to actually resize the image and, again, write to the out-file.
The first question I have relates to the header file, here is my code for calculating the header file:
bi2.biHeight = bi.biHeight *n;
bi2.biWidth = bi.biWidth *n;
int padding = (4 -(bi.biWidth * sizeof(RGBTRIPLE))%4)%4;
bi2.biSizeImage = (bi2.biWidth * sizeof(RGBTRIPLE) + padding) * abs(bi2.biHeight);
bf2.bfSize = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER) + bi2.biSizeImage;
And here is my code for writing the new header file (bi2 and bf2) to the out-file:
fwrite(&bf2, sizeof(BITMAPFILEHEADER), 1, outptr);
fwrite(&bi2, sizeof(BITMAPINFOHEADER), 1, outptr);
At this point I need to actually resize the image. As far as I can tell there are 2 ways to go about this you either have to use an array to store each line you want to print repeatedly (and then you can just write it repeatedly) OR you have to move the pointer back in the input stream and repeat the read/resize/write process each time you need to print the row.
It is this that I am stuck on, first of all, I am not sure what system would be better for resizing the image, although I am leaning towards using an array, and regardless, I don't even know where to begin when in implementing either.
So what I am asking for is, first of all, just a "double check" to make sure my header code makes sense. And second of all, a push in the right direction for actually resizing the image. Here is my complete code:
/****************************************************************************
* resize.c
*
* Resizes a BMP piece by piece, just because.

I am making an installation program. The set up project I made automatically detected dependencies. Dependencies were one ocx file I am using and some *.msm files. I haven't yet tested the installation program in the target machine.
My problem is that I have no control over the location of dlls installed in the target machine. Those *.msm files, I think
will be installed in the system32 (or wowsystem64?) folder. Do my msi installation program check the version of the dlls
already available in the target machine before overwritting them?
Another way will be to find out the dependencies with "dependency walker" and manually add those dlls to the
application folder of my installation program. But this way will be really difficult one.

I have a Third Party MS-DOS program, RUN.EXE
RUN.EXE do the following:
1. Read FILE.INP as input file and run its code execution.
2. When finish, RUN.EXE will produce FILE.OUT as the output of its code execution.
3. However, if calculation made in the code execution come to unsatisfied condition, RUN.EXE will terminate without producing FILE.OUT or partially produce FILE.OUT.
I want to write a program using MFC which I can set a several input case. The program should be able to:
1. Call RUN.EXE.
2. Wait for RUN.EXE to exit.
3. Continue with other code.
I can't modified RUN.EXE. I can't have RUN.EXE callback my program to let know it finish its work.
Are there any functions to call RUN.EXE, a MS-DOS program? Are there any way for the program to check if RUN.EXE finish its work and exited?

how to split a child window in an MFC MDI program.
Splitting Child Window in MFC MDI Program
[URL]
For my purposes, this achievement is practically useless because I cannot find a way to pass text from one CRichEditView window to another.
Given two CRichEditView windows, CInputViewView and COutputView as child windows in an MFC MDI app, my goal is to capture text in the former and print that text in the later using a button click.
Using what appeared to me to be a logical way to proceed, I tried variations of the following code:
Code:
void CMainFrame::DoSomething() {
//MessageBox(_T("Like What ?"), _T("Do Something"));
//CInputViewView * pin = (CInputViewView*) GetActiveView();
CInputViewView * pin = (CInputViewView*)m_wndSplitter.GetPane(0,0);
pin->GetWindowTextW(m_csDisplay);
[Code] ....
None of this works and even the attempt to access the pane results in an app crash in winsplit.cpp.
Code:
#ifdef _DEBUG
void CSplitterWnd::AssertValid() const {
CWnd::AssertValid();
>ASSERT(m_nMaxRows >= 1);
//..
I am not exactly sure how to do this and i keep running into problems. This is my code here that works.

struct record {

double quiz2;
double midyear, midyear_one;

This is the problem in detail:
I have a VC++ project to create a DLL that will be used as a Plug-in in an external programm. This DLL uses some MFC functions. The initial configuration of the project was:
-Use of MFC: Use MFC in a Static Library
-Common Language Runtime support: No Common Language Runtime support
-Runtime Library: Multi-threaded Debug (/MTd)
This configuration worked fine, there were no compilation errors and the resulting DLL worked correctly.
The problem came when it was necessary to add to the DLL some functions of .NET, using the namespace System and similar. To do that, I had to change the Common Language Runtime support, to Common Language Runtime Support (/clr). Then, when I tried to compile, I got this message:
'/MTd' and '/clr' command-line options are incompatible
So I changed the Runtime Library to Multi-threaded Debug DLL (/MDd). Then I got this error message:
Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version
So I also changed the Use of MFC to Use MFC in a Shared DLL.
After this, the compilation was correct. Then logically the size of the generated DLL is smaller, but this new DLL does not work correctly, the external program in which this DLL is used crashes.
I don't know what to do to fix the problem. Maybe I need to add some other DLLs or files to the directory where the DLL is located, where the external program uses it. But I would prefer to include a single DLL file, but this seems to be incompatible with the use of .NET functionality.
Write a well-commented C++ program that reformats and outputs the date. Prompt the user to input the date in the format dd/mm/yyyy and outputs it in this format month, dd, yyyy. For example, 07/06/2012 is displayed as June 07, 2012. You are provided with the file months.txt containing the months and their corresponding numbers, for example 01January 02February etc. Use getline(monthsFile,monthString) to read in a string from the file, and use the monthString.find() function to search for the number and extract the corresponding month.
-confused by the way she told me to use getline(monthsFile,monthString) => if I just do it like this I only get the first line from the txt file (01January)
-if I try putting all the months on one line in the txt file (which i'm not even sure i'm allowed to do), I'm not sure what to do for the length of my substring output. if I make it long enough to fit longer months like September, someone entering may gets both may and june in the output
-if I input all the months into separate variables, I'm not sure how to make it only output the month entered by the user
the months.txt file is as follows:
01January
02February
03March
04April
05May
06June
07July
08August
09September

I've been writing some code and this is part of it:
Code:
...
URLDownloadToFile(NULL, _T("http://something/something.txt"), path, 0, NULL);
return 0;
}
The file gets downloaded successfully but the downloader wont exit (return value 0). So it remains active.
I am sure the problem is URLDownloadToFile()
I am using Visual Studio 2010 Express.
I have an interesting (and incredibly frustrating) problem where my application runs fine, but ONLY when a debugger is attached to it.
I can build in both Debug or Release and double clicking the execuable causes it to crash before the window is drawn. However if I launch from the IDE (VS2010), again in both Debug or Release mode, the application runs perfectly fine.
How to debug in this situation.
I am using VS2010 in Windows 7, C++ with MFC. This is an application which has been migrated from VC++ 6 to VS2010. Note, it works perfectly when built from VC++ 6.
I am trying to figure out how to create a program that will draw a triangle using *'s with a base the has a user-inputted number of *'s like so:
*
***
*****
It needs to take a user inputted number and draw a pyramid like the above pyramid with the number of *'s in the base matching the user inputted number (i.e., user enters 10, so the triangle has 10 *'s in the base). I figured it would be best to first create a loop to draw out the correct number of *'s before trying to create another loop to draw out the correct number of spaces, to properly align the *'s into a triangle shape.

In a nutshell, my program will read the duration of each action potential from a point called "dVmax" (where the upstroke is at its maximum upward rate of change) to the point of 90% repolarization (on the downstroke where 90% of the total wave amplitude is subtracted from the volts at peak amplitude).

I have written a MFC dll to interact with an API and it is run by the target program. the first 100 bars are drawn properly but then the program ceases to operate. I am guessing I have a memory leak but I probably just dont understand what I am doing as I am quite new to programming MFC GDI. Here is my code that causes the trouble...
The variables coming in are commented out to facilitate testing and so it would be displaying the same bars over and over because of this. it worrks for 100 bars, then crashes.
void MainDlg::SS_UpdateChart() {
// the chart plot is completely recalculated each time a new bar is shown
// 300 is plottable height
// 400 is plottable width, 39 bars

I'm transferring a unicode string from one program to another with UTF-8 encoding.
Program that is sending:
Code:
// Convert path
std::wstring_convert<std::codecvt_utf8<wchar_t>> utf8_converter;
CString arg = L" /PATH="" + CString(utf8_converter.to_bytes(path).c_str()) + L""";
Program that is retrieving:
Code:
// Restore original path
std::wstring_convert<std::codecvt_utf8<wchar_t>> utf8_converter;
std::wstring path = utf8_converter.from_bytes( argument );
Everything has worked fine, until running on a Japanese edition of Windows.
The "byte path" then looks something like "C:¥Users¥d✝?✝a ,?¥AppData¥Local¥Temp¥file.txt".
"from_bytes()" will throw an std::range_error exception "bad conversion".
The program works fine when working with Japenese writing inside paths in the English edition.
What could be causing the "bad conversion"?
