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.

I am working on application to work with images. How to open/read images, whether it is jpeg, png, bmp or tiff and get it to bitmap. Is there some universal command for this or I will need more commands, every time testing the extension or format and then to use different method to read the image? Best would be to do it automatically, but I don't know such command.

View 2 Replies View RelatedSince SDL doesn't have it's own function for rotating images and I'm tired of storing multiple angles of the same sprite in a file, I created my own function for doing so:

The problem is while Spin does spin the surface correctly, some pixels are rotated to the same new position so gaps appear in the returned surface. I need a way of filling in the gaps so the returned image looks better. A link to a program I made that uses this function is below so you can see the problem that I'm talking about. [URL] ....
I currently use SDL 1.2. Could my problem be fixed if I used 2.0? For example, does SDL 2.0 have a built in function for rotating surfaces?

I am currently coding a 2D game in Visual Studio 2013. All of the .png graphics are saved in an absolute directory (for example, "C:/gfx/example.png"). Although this works for testing the application on my own system, I would one day like to release it (although it won't be commercial, as I am just learning). I could put all the of the image files in a relative folder, but I do not like the idea of my graphics being out in the open like that.
Is it possible to compile these images into the application itself? I had been researching resource files on Google, but I am still not completely sure if this is what I need to be using. Even if it is, I am using the express version of VS, so I do not have access to the editor. If resource files are what I am looking for, do I have to purchase an upgraded version of Visual Studio, or can I use another editor?

My application requires the user to add sales to images, this is done by displaying the image for the GUI, and then the user would add sales using that images ID which is brought in from the database.
In part this is 2 questions, first question is what is the best way to generate a List for use when adding the sales to the database. The List would need multiple strings for each sale. So for example:
Image 1 (Sale)
- JPG ID
- Product ID
- Product Quantity
So i'm going to assume i'm best creating a new instance of a custom class for each sale, and then add each instance to a List<Sale>?
public class Sale
{
public int SaleID { get; set; }
public int JpgID { get; set; }
public int SaleQty { get; set; }
}
Then I need a decent way to update this List with the GUI controls. So maybe get the JPG ID and set name of the Sale Class Instance to the ID, in this way its unique and I can update that instance when it comes to increasing the sale of a product or decreasing it.
Second part comes to the design of the GUI of adding sales, when I made this using HTML/PHP that was easier. It looked something like this:
If I wrote some code to generate that kind of design again in C# it going to require many Controls, wouldn't that be a bit intensive on the system? I just want something which looks great but also functions good.
At some point I'm going to switch to WPF, but I just need to get a working prototype working now which my client can use, and then update it when I have more time as I have got other Web Related projects that need doing, so at the moment WPF is out of the question.
Here's what i'm searching for: I have a form with 3 pictureBoxes (pictureBox1,2,3). The form also contains one button.
What I want is that when the user clicks the button (so button_click event) that the 3 pictureBoxes each show a different picture. And when I click the button again again 3 different pictures will load.
I already found out that I need to make an arraylist for the pictures (there are about 100 pictures). A System.Random
to select random images. But I have absolutely no clue on how to write this code.
I'm using C# with VS 2010, and I've created a .rdlc report file with 1 image boxes on it. How do I add images programmatically to this report file? Images are generated at runtime.
