Great, thanks. Took me a while to figure out what the results were but makes sense.

Now for the next challenge: For Generics collections you can do object.GetType().GetProperties()[0].PropertyType.GetGenericArguments()[0].Name for example to find out what object is contained by the enumerable, what would the equivalent be for an array?

If I've understood correctly, you need to look at the ElementType of the object:

<br />
int[] myarray = new int[10];<br />
Type arrayType = myarray.GetType().GetElementType();<br />

will return System.Int32

It definitely isn't definatley

You need the ToolboxBitmap attribute. A couple of issues with it that I've found.

It doesn't show at all if the control/component is in the same project.
If it's a component, it will only show the icon in the designer (not in the toolbox for either control or component) if it's in a seperate project in the same solution.
Works fine if the output dll is used as the reference!

Is this it :

[System.Drawing.ToolboxBitmap(typeof(WebCamCapture), "CAMERA.ICO")] // toolbox bitmap

Second please don't post so much code only the relevant problem areas

Third when posting code please use the code block then people can read it easier and follow the code.

and finally what error message are you getting?

Hi all,

Can someone tell me a way to add text and an image on a ListBox. Actually I want to add an icon in between text.

I can add text there, but stuck with the image.

Thanks all.

I appreciate your help all the time...

You may be able to do it by setting DrawMode to one of the OwnerDraw modes and using the DrawItem event.

Configuration file for data inputs.

AksharRoop20-Mar-09 0:36

Hi All,

I wrote an application that reads web page contents and send to specified email addresses.
I want to make this configurable; i mean a user should be able to set/change at anytime the to,from,subject etc. details.

I am new to C# but i know that app.config is one way to do this, but what i have read in forums that people generally use it only for installation configs.

Is there any other way where a user would be able to provide input in key-value format?

Thanks,
AksharRoop

Re: Configuration file for data inputs.

DaveyM6920-Mar-09 1:01

Use the application settings. Project|Properties|Settings. Create any fields you need making sure the scope is User.
You can then recall these using
Properties.Settings.Default.YourSettingName
and saved using
Properties.Settings.Default.Save();

Add a "Settings" file (using the VS add new item option), name it something like "MySettings"

Open it up and add your various different settings, set a type for them, and provide default values. (Make sure they are set to "application" scope not "user".

In you program you can read the values by doing MySettings.Default.MySettingValue.

When you compile your app you'll find the defaults are added to the app.config file.

in the bin\debug\ directory you can edit the exename.config file and make changes. when you run it, it will use the value from the .config file.

(The default values are actually also compiled into the assembly, so if you delete the exename.config file, or remove any values it will still revert to the default ones that are compiled into the assembly.)

Alternatively, if you set the settings to "user" mode, you will be able to write changes to them in code, and call MySettings.Default.Save() to save the changes to a user.config file that is stored in "c:\documents and settings\username\localsettings\application data\appname\appversion\user.config". If you did this you would also need to provide a configuration form for the user to enter their values and hit save.

Why not? You have posted this question before and if you do not give any more information, most usefully the section of your code which fails to do what you think it should, then it is unlikely that anyone will be able to help you.

I have developed a c# speech app using sapi 5.1..I use cfg..In my code I have a line where A messagebox is displayed..When this msgbox is displayed, the speech does not get accepted..it seems I have to hook the messagebox text to the grammar..I don't know how?? Anyone willing to help???

Re: Hooking MessageBox YES/NO button Text

Eddy Vluggen20-Mar-09 2:14

The MessageBox.Show is blocking, meaning that it will wait with execution until the user closes this messagebox. My guess would be that the agent only listens when the application can proces the information.

Well my first suggestion would be to try and get the contrast stable. Then attempt to convert to a binary image (i.e only either black or white pixels)

then you will need to produce some sort of scanning algorithm to detect black data and white space. then you need to research the formats of 2D barcode formats so you can make sense out of your data results.

Basically, its not an easy task so good luck!
