Visual C++ :: Why Getting Error 193 With CreateProcess

Jan 2, 2013

on a customers pc I have the following problem:

I want to run an exe file with CreateProcess, but this generates the error 193 which means

ERROR_BAD_EXE_FORMAT
%1 is not a valid Win32 application.

This is strange because there are no known problems with this file before for many years on many different windows versions.

The customers uses win7/32.

I use it with win xp and win7/64.

The file was compiled with vc 6.0.

What can cause this problem?

Visual C++ :: Error / DoModal Is Not A Member Of NewDialog

Mar 11, 2013

I am working through these tutorials:

[URL]

I haven't had to modify them much for VS2010 so far. Right now, (I think) I have created the dialog box, and the menu as a class and a resource, respectively. However, when I call

Code:

void MFC_Tutorial_Window::OnClickDialogNew()
{
NewDialog dlg;
dlg.DoModal();
}

I get an error 'DoModal' : is not a member of 'NewDialog'

I suppose somehow I need to link the menu to the dialog box?

I believe I've added the references, included the libraries and essentially followed the instructions. Apparently I'm not very clear on how to make resources interact with new classes.

Visual C++ :: Compiler Error With Cout Object

Dec 15, 2012

I am asp.net C# developer. I decided to tackle C++, so I started today. This is probably something simple I am sure.

Code:
srand(static_cast<unsigned int>(time(0)));
int choice = rand() % NUM_WORDS;
string theWord = WORDS[choice][WORD];
string theHint = WORDS[choice][HINT];

[Code] ....

The error is happening on the last output operator, just before the jumble variable on the last line.The error is:

Code:
Intellisense: no operator"<<" matches these operands

operand types are: std::basic_ostream<char, std::char_traits<char> <<std::string

I understand what its saying, but jumble is a std::string

Here are my preprocessor directives and using statements

Code:
#include "stdafx.h"
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

Visual C++ :: Project Link Error Not Added Lib

Mar 31, 2015

I have a VC solution . This solution contain 1 execute project and 10 library projects. The libraries added to the execute project by

#pragma comment(lib,"../outputbin64/lib/mylib").

When i comment these lines to not be added these libraries to the execute project , i will have link error like this :

LINK : fatal error LNK1104: cannot open file '../outputbin64/lib/mylib.lib'

My library projects not added to execute project with another way.

My question is why the execute project will link the libraries that not added to project programmatically?

Visual C++ :: Input Validation Error Using Arrays

Jul 18, 2013

I have not completed this program yet, but I have already run into a snag. For the Input Validation part, every time you enter a number regardless if it is positive it will still display the cout statement: "Please enter positive values". The program runs correctly where I currently am at, but it just keeps reading that statement even if a user enters a positive value. I have run the debugger, but it really is not showing me anything other than I notice it jumping to that statement after every value that is entered.

Here is my code, once again I have not finished this yet, but I would really like to get this fixed first before I continue. I will keep debugging in the meantime...

Code:
// A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 X 7 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey. Then it should create a report that includes the following information:

// Average amount of food eaten per day by the whole family of monkeys.
// The least amount of food eaten during the week by any one monkey.
// The greatest amount of food eaten during the week by any one monkey.

// Input validation: Do not accept negative numbers for pounds of food eaten.

#include <iostream>
#include <iomanip>
using namespace std;

int main() {
double totalAverage = 0; // variable to store the total average, initalized to zero

Visual C++ :: Exit From DLL Function When Error Is Encountered?

Oct 23, 2012

Say I have a dll that performs some mathematical parsing and calculations. The calling function is only a single C -linkage wrapper function in the dll. I can anticipate likely errors and program the dll methods to do several things when an anticipated error is encountered. (For now, let's not worry about unanticipated errors).

1 - send an error message to the user application using WM_COPYDATA
2 - throw an exception (assuming the calling app has used the try catch scenario)
3 - try to gracefully recover from the error within the dll and keep on going (jump to some safe place - but how ??)
4 - don't throw an exception from within the dll but halt the program (not very nice - the user won't know what happened)

Previous discussions on the matter have predominantly expressed the opinion that it is bad to throw exceptions from within a dll.

Long ago there was in use setjmp.h and something like

Code: if(setjmp(e_buf)) return -1;

But I believe this was only for old C applications - I'm not really sure. But at least someone back then recognized the need for getting back to a safe place in a process.

Visual C++ :: Error / M4 Failed With Exit Code 255

Dec 8, 2013

Basically, I'm moving a VC project from my Windows 7 build machine to a new build machine that's running Windows 8.1. One of the pre-build steps (for a particular project) runs a script which needs to call the M4 macro processor (which is installed on my C: drive). I've been pretty careful to set everything up the same on both machines (including my PATH) but when I try to build the project on my Windows 8 box, MSVC's IDE shows me this error output when running the script:-

Visual C++ :: Error Assigning Pointer To Iterator

Nov 27, 2014

im trying to port a code from vc6 to vs2013 and im having this error

Code:

Error11error C2440: 'initializing' : cannot convert from 'char *' to 'std::_Vector_iterator<std::_Vector_val<std::_Simple_types<char>>>' on this line

Code:
vector<char>::iterator BufIt = (char*)lpBuffer;

what i do with this is to stack fragments of data of type char* coming from a socket in buffer to a vector that acts as buffer, I do this since I transfer big chunks of data and the data gets fragmented by the nature of the sockets, I stack the data once its complete I retrieve the final result from the vector.

this code worked flawlessly for long time but now Im trying to port and compiler throws this error, whats the new way to assign a char array pointer to a iterator so i can stack it in the vector.

Visual C++ :: New Linked List Error - Undeclared Identifier

May 30, 2013

I dynamically allocate a new list in the recMergeSort function which should run a constructor but when it get to the functions that use it, I get error C2065: 'otherHead' : undeclared identifier. I have tried setting it to NULL and it didn't work. I even copied the default constructor to a set function and I still get the errors.

Code:
template<class Type>
void unorderedLinkedList<Type>::recMergeSort(nodeType<Type>* &head) {
otherHead = new nodeType<Type>;
if (head !=NULL)
if (head->link != NULL)

wonder if I'm sending the correct data type. Here is the heading of the functions that I'm using from the book.
