Re: how to get the images as output in run time - C# Discussion Boards

I have an app which defines several custom configuration classes derived from ConfigurationSection and ConfigurationSectionGroup.

In a dll I do this:

string exePath = Application.ExecutablePath;
Configuration config = ConfigurationManager.OpenExeConfiguration(exePath);

It works. Later I do:

foreach (ConfigurationSectionGroup childGroup in config.SectionGroups)
{
...
}

That works until childGroup is one of the ConfigurationSectionGroups defined in the application. Then I get a TypeLoadException: "Could not load type '[the_section_group]' from assembly '[the_dll]'."

Is there some way I can make it load the custom types from the parent app?

Thanks in advance for any pointers.

Regards,
Phil

In the App.config file there is a section named configSections

The "type" member is used to specify where the type that implements the configurationSection lives e.g.

<code>
<configSections>
  <section name="DataSourceProviders" type="Data_Models.Configuration.DataSourceProviderCustomConfigurationSection, Data Models, Version=1.0.2337.18582, Culture=neutral, PublicKeyToken=null" />
</configSections>
</code>

Doh!

I knew that, but I'd copied part of the app.config from another project and forgotten to change that bit.

Many thanks for your light in my darkness.

How do you want to display the image?

Can you give more details of what you require?

i m using VC# using smartphone 2003.one image is dispalyed as a back ground image and another image(Stretchimage) is displayed as a superimposed on the background Image. the stretch image should be displayed in run time only.
direct path of the image should not be given. we declare in one variable(in that variable we have to give the path) and we call that variable whereever we want.

So basically:

[object].BackgroundImage = Image.FromFile(yourfilenamehere);

Is that what you want, or do you want it embedded in the executable? (It doesn't sound as if you want this done)

What's the error message or compiler error displayed?

I can, but then if we find a solution other people can't benefit your problem (which is one of the ideas behind these forums).

Kmurthy wrote:

What do you mean by this, is part of the image transparent?

no,two different images.first one is the background image.another one is superimposed on the background image.no transparent images.

Easiest way would be to add a PictureBox control at runtime and load the picture from the file, e.g.

void LoadPicture()
{
  PictureBox picBox = new PictureBox();
  picBox.Dock = DockStyle.Fill;
  picBox.Image = Image.FromFile(filename);
  this.Controls.Add(picBox);
}

when im using the from file it displays the error like this. 'System.Drawing.Image' does not contain a definition for 'FromFile'

Try:

.BackgroundImage = new Bitmap(filename);

stil it gives the same error. and there is no property called "BackgroundImage".

Sorry it's the Image property on the PictureBox control.

after using image property also,it gives the same error.
In FromFile we have to give the filename or the path of the image.

They're the same thing aren't they, you can use a relative path or an absolute one as long as the image is somewhere on the filesystem.

Check the documentation for the Image object and see which methods are supported by the CF (I don't use the compact framework so I'm guessing (intuitively) here).

try out

catch (Exception e)

The reason you get this compilation error is that you method declares that it will return an instance of DataSet, but not all paths return such an instance. Look at what happens if an exception is raised.

To solve this, you need only to put this line:

outside of the try{}catch{} block.
