C# :: Best Way To Store And Load Image Into Access Database?

Dec 12, 2014

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();

[code].....

C++ :: Creating Databases And Indexing One Image Per Database - Multithreading Synchronization

Nov 1, 2013

My below code is createing databases(database here is a kd tree) and indexing one image per database. I have two classes LastDatabaseTndexingPolicy and another forwardingDatabaseaccessor.cpp .

I am calling the GetDatabaseToAccess() function from forwardingDatabaseAccessor.cpp class .GetDatabaseToAccess() function is present in LastDatabaseTndexingPolicy class and it returns the database created as a pointer and using that database pointer we call another function which actually indexes the image to the database .

Now my issue is i am not able to have multiple threads act on the following functions as DatabaseAccessor_ptr db which is in the following file is coupled with two functions and however i put locks in the LastDatabaseTndexingPolicy file as below i end up getting synchronization issue ..........

Hence now i am using a single lock in forwardingDatabaseAccessor.cpp and serializing the code,. How can i change my design to parallelize this code .........

In ForwardingDatabaseAccessor.cpp we are calling function from LastDatabaseTndexingPolicy as shown below:-

DatabaseAccessor_ptr db is something which needs to be synchroinized. I tried createing 256 databases with one image each and when i run this code i ended up creating 175 databses and though i was restricting in code with locks that every database has only one image i ended up having two images in single database ..... ideally i had to get only one image per database but i got two images in few of them hence instead of 256 database this code created 175 or so databases.

indexing::IndexReturnValue ForwardDatabaseAccessor::index(cv::Mat image,
const std::string& imageName, features::Camera::Type indexCameraType,
features::Camera::Type recogCameraType) {
DatabaseAccessor_ptr db = this->IndexingPolicy_ptr->GetDBToIndex();

[Code] .....

C# :: Compare The Image Of A Button To Another Image In Visual Studio

Jul 3, 2014

Im trying to compare the image of a button to another image in Visual Studio like so...

//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");

[Code]...

btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))

I do have a feeling ive done something wrong here (Yes im a noob /> )

Variable active, is the same image as the buttons default (Well should be)

C++ ::  Read From File And Insert Into Linked List

Feb 12, 2014

I have a program and function i'm having an issue understanding. Here is what it's doing in the main.

int main() {
orderedLinkedList<MemberDO> memberList;
MemberDO::readFromFile("Member.dat", memberList);
return 0;
}

So it is creating a linked list object using the MemberDO class type which has a int, string, char and double. Then it will call the readFromFile static function in the MemberDO. So this is where my problem is I have this function

void MemberDO::readFromFile(char *fname, orderedLinkedList<MemberDO>& list) {
}

How do I read in each individual data member from the input then create a new MemberDO object and insert the objects into the linked list specified in the second argument list?

Here is the MemberDO class declarations

class MemberDO {
private:
int key;
string lastName;
char firstInitial;
double dues;

[Code] ....

I have a database of images and I want to store paths of all those images to a text file (lets say "images.txt"). I can then use this text file in c++ to extract images one by one by using getline() in a loop.

I don't know how to store image paths to a text file.

C :: Read A 24 Bit Image Using 2D Array

Oct 29, 2013

I am trying to read a 24 bit image but I'm getting errors when I'm tryting to read the pixels.

-The reading part looks bad because I'm reading both headers field by field. But I'm sure that it is reading both headers correctly.

-Right now my biggest concern is to get it to read successfully an entire bmp image

I'm using this calculation to get my padding bytes:

padding bytes = [4-(3*width)mod 4]mod 4

When I use a 2x2.bmp file to test it, I get an error that the [1][1] pixel was not read. When I use a bigger image it gives me the same error after about 100 rows and then every pixel is an error from that point on. This is what I got so far:

Code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
const size_t cSizeofPixel = 3; //size of struct tPixel
typedef struct{
unsigned char blue;
unsigned char green;
unsigned char red;

[Code]...

I read this post Reading 24 bit BMP file into a 2d array.

I still don't know if my error is when I allocate memory to my 2d array, or if I'm doing the padding bytes wrong or if it is something else.
