this is my first question here.
I've made a small quiz project about the 199 world's states via Visual Studio C#.
therefor I collected all flags of every country and put them into a folder - you can imagine that i collected MANY.
To run my current project i need the folder with all these .gif images -
otherwise the startup will end in a fatal error. :-(
My question is if it is possible to integrate the images into my .exe file so that i can run it without that nasty folder. (Also important for future project with even more content!)
And if it is possible - how?
It would also be nice if you let me know how to use the images - what pathes they have got etc ... =)
Thanks in advance!

You can add a resource file to your application, by going to
Project >> Your Project Properties >>
Resources >> Create A Resource File.
You can then simply add any image to your application and reference it via your code. Select Images from the drop down on the top of the menu, and then click Add Resource >> From existing file.
After you save your resource file, you can then access your images via code, e.g.
> Image img =
> YourProject.Properties.Resources.Image1
However, with the number of images you have, and what I would believe you are using them for, I would suggest using a Image List, which you can add all of your images to, and access them via their key or index. e.g.
Image img = imageList1[0];
Or
Image img = imageList1["US"];
This can be found in your toolbox.
You can add the images as embedded resources. Then use the ManifestResourceStream from the Assembly to extract the raw byte data, and subsequently load it as an image.
Note: this is different from the answer/approach of Femaref below.
Every assembly in .net can contain so called resources. You can add them in the properties of a project in the resources tab. After that, you can access them via ProjectNameSpace.Properties.Resources.

I don't know if I asked it right, but basically what happened is that I made a winform app which loads its image from the resource folder.
The problem is that when I build the project and get the exe and give it to a friend, he won't have that resource folder like I do, so he'll get an error saying missing file.
How can I somehow mix, or combine, or attach the image with my app?
You need to add it to the project by navigating to the Properties Window and going to the resource tab and adding the image from there.
Alternatively, from the PictureBox Control you can import resource from your computer.
if you don't need to update it in the future, compile your program with the image property build action set to embedded resource.
if you need to change it in the future compile with property build action set to content.
In my C# windows forms application, I have an image that I used some where as part of requirement and I stored it in a folder named Images with in my solution.
But when I deployed it and installed the application on a user machine it threw me an error specified file not found
I used my image as follows
indexWorkSheet.Shapes.AddPicture(#"C:\Atlas Applications\AtlasPetroleumIndex\CLPetroleumIndex\Images\logo.jpg", MsoTriState.msoFalse, MsoTriState.msoCTrue, 155, 20, 180, 65).LockAspectRatio = MsoTriState.msoCTrue;
Create an Images folder in your solution in VS, then right click on it and go to Add -> Add Existing Item. Select the image you want, then once it's added to your project right click on the image and go to Properties and select Copy Always for Copy to Output Directory
If you want to prevent users from deleting your folder containing the logo file, you should definitely add this image to the Resources of your Project.
You can refer to the MSDN related page to do so. Your image will then be stored into the executable file of your application.
If you are also interested in storing other kind of user information, like general settings, preferences, user logo, etc... I suggest you take a look at this post.
First, please note I am a Java developer, started C# just few weeks back. Here is my question, it is about Visual Studio IDE.
I am using visual studio ide 2008 to create C# projects. I opened a new windows application, added a picture box to the form and now ready to add an image to it. I clicked the small black arrow button in picture box and it opens a dialog where we can put images.
Now, the question comes. In my c# book, they add images using the first option "Local Resource". Anyway, since I have to add number of images, I selected the "Project Resource File" and added all the images to the folder at once. Now I am working smooth without any issue. But, I can see the "Form.resx" file is empty (in my book, they show that file contains all the image files).
I want to know whether what I have done is correct or not. Even though that file is empty, no errors in the program anyway. I don't know whether any issue will occur after the distribution, like missing resources (In Java it normally happens unless otherwise you put all the resources into a new 'Package' inside the project. That's one of reasons I selected the second option when adding the images). Please help!
Your resources will be in a file called Resources.Resx (I think) this can found in your Properties folder in your project file
http://msdn.microsoft.com/en-us/library/7k989cfy(v=vs.80).aspx This link has some information about using Resources
Its better to add the files to the project resource if your going to need them on multiple forms in the project. If they are only going to be required by the current form, you might as well put them in the forms resource file
I have used a JPG for backgroundImage for an application form.
My question is that do I always need the JPG with the exe program?
So if I give my exe program to another user, the person won't be able to view the backgroundImage if I dont provide the JPG file?
another question is regarding the icons that I use for the program (exe icon and an icon that displays at top of your program).. are these icons stored in the program? or i need to provide the icon file(s)?
sorry i only have a machine and don't have someone to test for me.
cheers,

You need to add image as a resource for the Application. If you add it simply as a file link e.g. C:\somelocation as soon as that changes you loose teh image.
If its added as a resource then it is inculded with the build and always present for the Application.
To know more on how to do this look here:
http://msdn.microsoft.com/en-us/library/7k989cfy%28v=vs.80%29.aspx
http://www.homeandlearn.co.uk/csharp/csharp_s4p8.html
An easy test would be to put the .exe in a separate folder and try to launch it.
For the JPG it depends how you refer to it in your program, if it is a resource that you added it will be in the executable.
The icon should be in the executable already.
You can add the .jpg file as a resource in your application, which results in it being compiled into the .exe itself, giving you one less file to distribute.

Hello guys I think the question i asked in the previous post is unclear OK fine. i am explaining in brief.
for example.
I have a form where i have placed one textbox and command button.
I have fired a event when i click the button the text under the textbox change to "hello" ok fine.
what is my problem is..
the application is created and I published ok.
After some week I thought I want to update my application. where in the place of "hello" I want "hi". I know that we can compile the whole project and publish it.
but I don't want my whole application to be updated.
for example.
What antivirus company do they have a definition file where they only update the definition file not the whole application. after the update it applies to whole application.
I want my application also to do same process like antivirus company do.
You should read that "Hello" from a content file (XML). Then you can just push out the new file.
Use a configuration file. You can add an application.config (or if you're developing a web app, web.config) file to your primary project. Within this configuration file, you can define AppSettings (which are built-in, usually simple and atomic string or number fields that the application will need), ConnectionStrings (which specifically provide information applications will need to connect to a database), or custom configuration sections (used for more complex, related sets of data that are loaded into custom classes you define, such as a basic company profile). Within your code, you access AppSettings by using the static ConfigurationManager.Appsettings[] collection; you tell it the name of the setting you defined in the file, and it returns the value (or null, if it can't find the setting you defined).
Related, but different, is the use of Resource files. Resource files usually contain a dictionary of location-specific data used by the UI, such as text strings, icons and images. Actual resources can be compiled into one big file, or resource files can be a list of paths and filenames to the actual resources. You can use resource files to create different "skins" for your application to be used by different companies by referencing images to use for UI elements, or to translate labels and other text on your application's UI. Resource files are accessed through a ResourceManager; you tell it where the resource file is, and it will load the information into a similar "dictionary"; you then tell it the name of the resource and you get the resource back.
For your specific question, I'll answer the same thing as Henk. But, I think that your real question is "How I do create patch in .NET".
You can check this link:
How can I patch .NET assemblies?
You could design your application to use plugins. This way you only have to update a plugin and not the whole application.
if you want to create a patch for asp.net application , first of all , you have to deploy your project with Web Deployment Project.
then choose Create a separate assembly for each page and control output in output assemblies tab and re-build your solution .
the result of deployment is bunch of DLL which mapped to each page or control.
Now if you changed one page's data (in code behind) , you need to deploy your project again but in this case you can just upload the changed dll file.
