I am working to load CoInitialize using getprocaddress, but I don't know why this function fail and cash program! It didn't happen with other functions in other libraries like kernel32.dll. Here is my test :
Code:
typedef HRESULT (*pf)(LPVOID);
pf rf = (pf)GetProcAddress(LoadLibrary(ole32.dll), "CoInitialize");
CoInitialize(NULL); // This line crashes the program!!
why and how to properly load it ?
How to read dll files and i came up with this:
// DLL
Main.h:
#ifndef _MAIN_H_
#define _MAIN_H_
#include <iostream>
#include <stdexcept>
#include <fstream>
_declspec(dllimport) void testfunc( int a );
[Code] .....
Out: testfunc == NULL
What went wrong here?
I have a Visual C++ workspace that has 2 projects (1 exe & 1 DLL). I used Serge Wautier's tutorial [URL] .... to create (multi-language) resource DLLs (satellite DLLs) branching off the exe.
Now I have a collection of strings in the DLL that are shared in other projects. I created a satellite DLL for that DLL but can't figure out how to load it on-demand just like the exe's satellite DLL.
He used:
HINSTANCE hDll = LoadLibrary(szFilename);
AfxSetResourceHandle(hDll);
void CLanguageSupport::UnloadResourceDll() {
if (m_hDll!=NULL) {
SetResourceHandle(AfxGetApp()->m_hInstance); // Restores the EXE as the resource container.
FreeLibrary(m_hDll);
m_hDll= NULL;
}
}
etc etc ... for the unloading/loading satellite DLLs for the exe. But how to do the same for the DLL?
I need to open up and modify a user's registry key from a 32-bit service (note that the user is not logged in at the time.) I do the following:
Code:
//For simplicity error checks are not shown
//I also made sure to enable the following privileges:
// SE_RESTORE_NAME, SE_BACKUP_NAME
[Code]....
The problem is that the "SoftwareClassesLocal SettingsSoftwareMicrosoftWindowsCurrentVersionTrayNotify" key isn't loaded, even though I know that it exists in the actual user profile. I can verify that by loading the user account and by using 64-bit regedit.
I am trying to reuse some code from my Visual C++ 2005. I am using CArchive to ReadString the first line of a file into another string. However, I am seeing squares where there should be spaces when I view it in the debugger.

if( cfSAP.GetStatus(csRegExtractFileRemote, cfsStatus)) {
if( !cfSAP.Open( csRegExtractFileRemote, CFile::modeRead, &ef ) ) {
cout<<"FAILED

ef.ReportError();

I am not able to read the lines due to this bug ,
This is normal text file contains two lines of information like this

I am doing an exercise that reads in a text file and loads the data into a struct. My problem is it doesn't read anything from the text file. I think it's the way I'm loading the data. Oh, it does read in the first record that tells the program how many contributor records to create, but nothing after that. Here it is:
Code:
//
#include <iostream>
#include <fstream>
#include <cstdlib>
const int strsize = 30;
const int SIZE = 60;
struct contributions {
char fullname[strsize]; //name
double donation; //donation
[Code] ....
Here is the record input:
Data file:
4
Suz Stuz
55000
Froco Frock
5000
Yandi Yuck
100500
Dippy Dip
120000
9 records - each struct has two members; full name and donation. First record should be number of contributors ...

View 2 Replies View RelatedI'm trying to load a PNG image to use as texture, but when I compile the sdl window closes. I'm sure the error is in the function of generating the png texture, because when i don´t use this function, the sdl window does not close. So debugging using cout i found that the cout above glTexImage2D function, shows in console, but the cout in below of glTexImage2D does not work. Does not reading this image?
hear is the function

View 5 Replies View RelatedI'm working on a project, and I'm trying to fill in various vectors from a given input file. The input file looks like:
<catalog>
<book id ="bk101">
<author>O'Brien, Tim</author> ....etc
My load vectors function looks like this: void load_vectors(vector<string>&id, vector<string>& author...etc)
I can't assume a limit on the number of books etc listed in this catalog, so I'm using the eof() function. However, I don't know how to write the loop to gather the correct strings and place them in the vectors.
Code: while(in.eof())
{ string text;
int index, index2;
getline(in, text);
int index = text.find("<author>");
int index2 = text.find("</author>");
a = index.lenght();
author.pushback[i] = text.substr(index + a, index2);

Ive used a similar approach to extract data from a txt file before, however now it seems to crash when i get to the load, below is the code with a NOTE next to where it crashes. This is homework so no code but just information on why it was working for one dataset but not his new one.

I have a group assignment were we need to load sokoban levels from text file. We have loaded the file in a vector but how we can parse the file for it to be used during the game.
We read about malloc and know how to access each character from the vector, but how can we select a particular level after the user inputs an the level integer number?
E.g.
Level 6

So I am working on a FUSE filesystem and I currently have the need to load the contents of a text file into an array.
My array initialization looks like: char array[max_entries][PATH_MAX] = {NULL}
The reason I want to pass it by reference is that I want my function to return two values essentially. One a specific char* and the other an array like I initialized. My function proto type looks like:
char* load_meta(char* list[max_entries][PATH_MAX], char* path, int mode);
How I'm trying to call the function:
someChar = load_meta(&array, path_name, 1);
Within the function I try to edit the array by deferenceing it once, like this:
strcpy(*list[i], file_entry); // This seg faults
I'm trying to load a Quad with a Monster Image on it that will always face the Camera, a la Doom 2.
Now I don't know how to load an image with an Alpha part on it.
In 2D using SDL I always used tga files.
Here is my LoadTexture functions.
AUX_RGBImageRec *LoadBMP(char *Filename) // Loads A Bitmap Image
{
FILE *File=NULL; // File Handle
[Code].....
I have:
An Access database in which the picture right now is saved by its directory, together with other field like title, publisher, developer,..
Visual Studio form in which a load button gets that directory as text
Details button that reads the ID of a selected item (I have a list of games) and displays the corresponding picture by reading the directory
The problem right now is that once someone else opens the program on his/her computer, the directory changes, making the whole thing useless.
Is there a way to get around this problem? The books I've been reading don't really adress this.
Directory is a string in class 'Game'; it's short text in the database
private void buttonFoto_Click(object sender, EventArgs e) {
LoadNewFile();
}
private void LoadNewFile() {
OpenFileDialog ofd = new OpenFileDialog();

I've just started using the CImg library and when I try to load a picture with this code:
CImg<unsigned char> image("example.bmp");
It works perfectly. But when I try to type in the image file name using the console it gives me errors. For example, if I try this:
std::string input_file;
std::cin >> input_file;
CImg<unsigned char> image(input_file);
It doesn't work. The way I see it, I should be able type "example.bmp" into input_file and use it but it doesn't work, and gives me the error:
"error: no matching function for call to 'cimg_library::CImg<unsigned char>::CImg(std::string&)"
I have included iostream and string.h.
This seems like a fairly straight forward assignment. Load up a file that contains a series of int values stored in ASCII and print out the ASCII characters to the console.
The problem I am having is that I am getting the numerical value of bytes ("40" for 10 numerical values, "200" for 50 values). The numbers are generated randomly by another file, but I can control how many numbers are generated. For example, if I type in:
shell% cat tempfile
the output is as follows:
/8?qE?. Y4?(T???a???%@
but when I try to run it with my program:
shell% ./intcat tempfile
the output displayed is:
40

I have done a test, I have edited with the WordPad in Windows on my Local Webserver a file banana.h which contains a list of float arrays in order to extract one array and create a text file named ObjVerts.txt I have done a lot of search in the Web in order to find a small piece of code that can read the text file and convert it to a float array GLfloat, but I did not find any. I have found a lot of piece of code that read the file and make a NSData but many of the code seem to not work. It seem that the last statement return nothing!
NSURL *myurl = [NSURL URLWithString:@"http://localhost/ObjVerts.txt"];
//NSString *mystring = [NSString stringWithContentsOfURL:myurl];
NSData *mydata = [NSData dataWithContentsOfURL:myurl];
