All I am trying to do is create another source file in a simple Visual Studio C++ console application.
I get the following errors:
intellisense: expected a delcaration
error C2447: "{" missing function header
I didn't create another int main () in this source file, so what is causing these errors.
I am stuck in visual studio 2010 file I/O ... i placed file1 file2 using the following program under VS2010/projects/projectname/file, file1 and also in debug also once......I am actually using cmd line arguments in debug mode

I dont think in C++ forum the printf will do any problem...when i run the program it says "cannot open source file" and a window appears saying"Debug assertion failed"....and other details such as Expressionstream!=NULL).perror

Any tutorials on adding a UI to a console application? All I really need is a button that will run one function every time I click it.

I need that console wait the application exit before show me the prompt again. I tried on Visual Studio 6, 2005 and 2010 but the behavior is the same.

View 5 Replies View RelatedI'm building a simple system management console application. I've abstracted the console "Menu" and derived from it a "WelcomeMenu" class with public inheritance.
The problem is that when instantiating a Menu* object and assigning it a new WelcomeMenu...I'm still not able to use WelcomeMenu's "ShowWelcomeMessage() with the Menu* object. Instead, I get "error: Class 'Menu' has no member function call 'ShowWelcomeMessage().'

P1.StartInfo.UseShellExecute = false;

it is giving the exception "StandardIn has not been redirected"
I'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>

using namespace std;
void SendCommand(string command) {

I am using Windows 7 32bit OS and want to detect the CPU power button press event in my console application developing in C language.
I configured the power button setting to "Do Nothing" which is in "Choose what the power button does" options in Control Panel->Hardware and Sound->Power Options. So now i want to detect this power button press event and do some processing in my application then i will initate shut down from application itself. Looking for windows API details which will detect the power button press event.
I have been struggling to read a certificate in windows store from C++ DLL, but its not happening. from console application I can but when same code built as a DLL and tried to access from a separate console application. I think its not going to windows store to read the cert.
pCertContext = CertFindCertificateInStore((HCERTSTORE)*pCertStore, X509_ASN_ENCODING | PKCS_7_ASN_ENCODING, 0, CERT_FIND_ISSUER_OF, operator PCCERT_CONTEXT(), pCertContext);
int Error = GetLastError();
if (Error == 0)
LINFO << "

else
LINFO << std::hex << Error << '

it returns 80092004 GetLastErrorStdStr= C a n n o t f i n d o b j e c.
I am writing a program for my beginning c++ class. It is supposed to create an invoice in the console window. so far, everything is working perfectly, except for one thing. My invoice comes out looking like this:
696.60 - 27 Adult Meals at $25.80 each.
+ 46.44 - 3 Child Meals at $15.48 each.
--------
743.04 - Total Cost of All Meals (Add the above numbers together)
+ 52.01 - Weekend Surcharge (743.04 x .07)
+143.11 - Tax/Tip ((743.04 + 52.01) x .18)
--------
938.16 - Total Party Cost
- 57.50 - Deposit Received
--------
880.66 - Balance Due
- 32.84 - 3.5% Prompt Payment Discount (938.16 x .035)
--------
847.83 - Balance Due (If Paid Within Ten Days)
The problem is that if I add these numbers on a calculator, I get as result of $847.82, not $847.83. I checked them individually and they are all being rounded properly. If I add them up using the entire decimal value of the calculations, rather than the truncated value, I get $847.83.
So, the question is as follows: In C++, how do I do each calculation, round the answer to 2 decimal places, then use only the rounded number in the next calculation?
i have to create a console based application in c language that can join and split bitmap images. the requirements of the application are as follows :
1. Split Image
Enter number of parts:
Enter source image path:
Enter destination folder:
2. Join Images (all images should be of same width and height)
Enter image path:
Join more Image (y/n):
3. Exit
Take care of following things:
- Application should show number of images processed while running.
- Acceptable Image format is BMP only.
- Application should give all the validations for correct image name, type, size, path, etc.

I'm making a flash card type console application using visual studios 2013. The flash cards contain character that I can display using unicode. So far I am looking at about 200 characters across 2 unicode blocks which I don't want to hard code into my arrays. I thought of initializing my arrays using a loop. The only problem is I don't know how to add in hexadecimal. So is there a way to initialize my array without having to input 200 values my self? Also is hexadecimal addition possible without me having to write a function for it?

vector<INT> flags;

I know this is not probably the best way to but i am laying around and was curious if something like this could work . Are there any good C++ templates for CLI applications from which i could learn?

Now I am struck. How to to compile? I link all these file. I used following method:

gcc Sender.c -o Sender Sender.h
gcc Receiver.c -o Receiver Student.h
Then I run Sender and after that Receiver.I per my knowledge, Receiver should give difference but it gives error :
Code:
