Seriously, aren't there enough articles about this topic here on CP?
That's what the search function is for.

Hi
I would like to draw an image that contains lines , text and rectangles.
In order to draw it I need to use the graphics object.
Also I would like window\control will handle scroll bar, drawing the image automatically in case the image move with the mouse for example, so I was thinking to use image object in order to store my image
How can I export the image I created manually from graphic object (after I create all the items I want such as line, rectangle, etc on panel for example) to image object?
Thanks

You don't need to - just create a new Bitmap, the create a new graphics object, and draw to that
e.g. something like
Bitmap bmp = new Bitmap( 640, 480 );
using( Graphics G = Graphics.FromImage(bmp) )
{
G.FillRectangle(...);
}

OK Thank u all,
Itry to draw to bitmap and it work great
How can I display it in the form
Should I create picturebox control and load the bitmap to it?
I would like the form to create scroll bar automaticly if need (in case the form is smaller then the bitmap image)

Hi,
you can create a Bitmap, obtain the corresponding Graphics (through Graphics.FromImage), paint
to your hearts content, then use Bitmap.Save
BTW: there are several articles about Paint-like apps here on CP.

You've already asked this question dozens of times and been told that that is how it works. When the form is resized or covered up you are responsible for redrawing it at the size you want. There is no magic gdi+ routine that redraws or zooms in for you.

I've already given you the link to the chart control docs and samples.

Hello everyone,
I want to embed a resource file (xml file) into a DLL assembly and access the xml file from the DLL.
But I can not find sample code for me to do this. All samples I could find is dealing with embed and access image in resource file. Could anyone show me a sample please?
thanks in advance,
George

It's XML so just store it as a string. You don't need anything fancier than that. However, if you add a settings file and add it to there, you'll be able to change it by changing it in the config file ( although as it's an XML file, you may need to encode it, or put it in a CDATA section )

Thanks Christian!
If I have already added an XML file into my project, how to make it into a resource file into the final DLL assembly?
regards,
George

Assembly assembly = Assembly.GetExecutingAssembly();
string[] resources = assembly.GetManifestResourceNames();
Stream s = assembly.GetManifestResourceStream("YourResourceName")

Select the XML file, in the properties there is an option to make it embedded. I don't remember the name exactly.

I find this item. Do you mean this -- Build Action --> Embedded Resource?
2.
What is the differences between Build Action --> Embedded Resource and Build Action --> Resource?
regards,
George

Choose the property for that file, select "Build Action" as "Embedded Resource"
|
|
|
|

Thanks Navaneeth,
There is another option called resource other than embedded resource. What is the differences?

George

I have tried your samples but not working. Maybe I made something wrong. Here is my code.
I have a DLL and in the DLL I load resource by using the following statements,
XMLFile1.xml is a resource file for the DLL project and I mark it as embedded resource from build action. The issue I met with is s always return null when executing the following statements.
Anything wrong or any ideas to debug further?
Assembly assembly = Assembly.GetExecutingAssembly();
string[] resources = assembly.GetManifestResourceNames();
Stream s = assembly.GetManifestResourceStream("XMLFile1.xml");

I read the link below you recommended, but still confused about what means Resource. Here is the description from the page -- " embeds the file in a shared (by all files in the assembly with similar setting) assembly manifest resource named AppName.g.resources.", but when I mark the XML file to be Resource other than a Embedded Resource from buuld action, there is no file called AppName.g.resources generated. Any ideas?

Yes. When you embed resources via visual studio, it appends the namespace name along with the resource name. Assume your resource (XMLFile1.xml) is in namespace SampleNameSpace, then your resource name would be embedded in assembly like SampleNameSpace.XMLFile1.xml. So to get your code working, change it to
Assembly assembly = Assembly.GetExecutingAssembly();
Stream s = assembly.GetManifestResourceStream("SampleNameSpace.XMLFile1.xml");Note : the namespace name and file name is case sensitive
You can embed resources without the namespace prefix if you are using command line.
csc /resource:XMLFile1.xml YourClass.cs but it is very tough to use.

Honestly, I don't know and I'd suggest not to break your head by thinking about such a small thing. Be productive and write code instead of thinking about trivial things like this.

Thanks Navaneeth,
I did search for a whole day during my relax time but find no solutions. I am not sure in C# we must include resource file into the same assembly where code resides. Any ideas?
regards,
George

Several my application show how to access embedded resources. For example this one: Convert MP3 to EXE[^]

Thanks Giorgi,
I have followed your patterns and it works. I have another question, is it possible to put resource into another separate file, and during runtime the DLL could finds and loads the separate resource file?
regards,
George
