The way to get better is by reading. In VS.NET's Help index type "Graphics.DrawImage" or search for it on http://msdn.microsoft.com/library[^]. This forum is for helping with specific problems, but only you can teach yourself what you need to know. Not even schools can do that - they merely give you the tools and training with which to start your real education.
Most of the .NET Framework SDK documentation includes samples that should help you. There's also hundreds of articles here on CodeProject, many of which explain how to draw in .NET (just keep your search limited to C# and .NET, which you can check in the search page). That's why this site exists: to help new - and even experienced - programmers.

Good day all…
I am experiencing a problem in using the Form Icon property. I have created a custom icon for my app and cannot display the icon (in the design view) by setting the property using the browse function. It displays properly in the properties view but not on the title bar. I get a default icon (on the title bar) of which I cannot determine its origin. This icon is not the system default icon.
Thank you very much in advance for your assistance
Have a great coding day.

Open your icon in the icon editor in visual studio (if the .ico file is not part of your project, add it to the project and then double click it to open it in the editor). In the icon editor, there will be an enlarged view of your icon. Right-click anywhere in that view (not on the icon itself) and select "Current Icon Image Types | 16x16, 16 Colors". You should now see the smaller version of your icon which can be edited. If you have not made any changes to this before, then that would explain why your small icon is the default icon.
Hope this helps.
Best Regards.

Good day Matt
Thanks for the assist. I was trying to load a 32 x 32 icon for the title bar.
After changing the icon to a 16 x 16 icon it became present in the form design view.
Have a great coding day.

Hi all,

Is it possible ? I have tried it by C# but some classes needed are missing
in .NET CF, so I try to find to implement it in VC++ in pocket2003. So what is the corresponding command for register the window message in VC++ ?
Thanks

Hi all,
How to create COM by C# ? I have searched but can't find detail enough information to create it, including the interface...etc.
And can I use the c# com in VB script in a html file ?
e.g. in the VB script, I will program it as,
Set comObject = new CreateObject("comObject")
Thanks
Patrick

I am currently working on creating a COM+ component using C#. I can't asnwer your question about calling it from an HTML file, however, I have successfully run my COM component from a VBScript on the command line. Do a search on google for System.EnterpriseServices.ServicedComponent (you will inherit from this class to create your component). You will find several articles online that explain how to do it. Once you have successfully created your component, you simply register it with the regsvcs command line tool. Then you will see it in the component services control panel. You then instantiate it from your script as you would any other COM component.
One thing to keep in mind is that while the API to do all of this seems pretty clear, in practice it proves very complex and confusing. I am currently having some problems myself that I hope to figure out soon. Anyhow, let me know if you can't get going. I'll help you out however I can.

Doesn't work as Console.ReadLine return a string:
int x = Console.ReadLine();
...
Console.WriteLine(x);
So how can I convert the string to int (or float or short and so on) ?
String object doesn't seem to have ToInt member either ...
I still can't belive I don't know this one ...
Regards, Desmond

int x = Int32.Parse(Console.ReadLine());
This one will also throw an exception if it isnt a number string

Does anyone know the correct way of marshalling inline multi-dimensional arrays?
I have the following structure that I want to reproduce in C#:
typedef struct tagMyStruct {
WORD Version;
char szName[3][256];
} MyStruct, *MyStruct;
Now if this was just an inline array:
typedef struct tagMyStruct {
WORD Version;
char szName[256];
} MyStruct, *MyStruct;
You do this:
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)] public struct MyStruct {
public int Version;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=257)]
public string szName;
}
But it is not, so it is not that easy. I have tried, without success:
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)] public struct MyStruct {
public int Version;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=257)]
public string name1;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=257)]
public string name2;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=257)]
public string name3;
}
Any ideas?

Create your C# component as a System.EnterpriseServices.ServicedComponent, register it with regsvcs, and call it as you would call any other COM component from C++.

Hi
Type of enum member is underlying type for the containing enum, then why casting is necessary on enum member?

Because it isn't the underlying type (even though the value might be physically stored as such), it is the type defined in your enum.
Do you want to know more?

It so happens that I have a class named Poetic which is the rootelement. When SERIALIZED --using the XMLSerializer--the outcome should be:
<Poetic xmlns:xsi="http//www.w3.org/2001/XMLSchema-instance" xsi:noNameSpaceSchemaLocation="http://poetic.publisher.com/xmlcomm/poetic.xsd">
My Class declaration is:
[System.Xml.Serialization.XmlRootAttribute("Poetic")]
public class Poetic
{
// properties, methods and the like in here
}
When I serialize it comes out:
<Poetic xmlns:xsd="http://http://www.w3.org/2001/XMLSchema" xmlns:xsi="http//www.w3.org/2001/XMLSchema-instance">
So...
1. How do I get the xsi:noNamespaceSchemaLocation into the element using SERIALIZATION. I know the noName.. is part of the w3 spec.
2. How do I get rid of the xmlns:xsd="http://http://www.w3.org/2001/XMLSchema".
Thanks,
Guillermo Jimenez

Try the following:
[XmlRootAttribute("Poetic", Namespace="http://YourNameSpaceHere")]
class Poetic
{

Hello,
I have a DateTimePicker control with check boxes on a form (well, several, but the behavior is the same for all.)
In design time, I set the Checked property to false. And they appear without the check.
When I run the app, the control is drawn checked, altough looking in the debugger, the Checked property is false. Once I start clicking on the checkbox, it checks and unchecks correctly.
So, we have it with Checked==false and check drawn. If I click on the checkbox, the check is cleared, Checked is still false, and I get no ValueChanged event. If I click again, everything works as expected (Checked set to true, and ValueChanged event).
Is it a bug? or am I missing something?
Thanks!

Hi all,
Is Window messaging by using the RegisterWindow MEssage API in C# a good way
to perform messaging between IPC ? How is it compared to IPC by MSMQ and .net remoting ? Is RegisteredWindow Message supported on Window 98 and Window ME also ?
Thanks
Patrick

Check out the documentation for the function in the MSDN Library[^] for questions like these. In this case - if you understand what RegisterWindowMessage does - the answer should be obvious. You can't send unique messages without registering them.
What's best? Whatever is best for your situation. If you're communicating between two managed applications, I would not recommend Windows messaging. Use .NET Remoting with a TcpChannel. In .NET 2.0 they are also adding an IpcChannel which, IIRC, uses named pipes. Both are pretty fast, though there's a little extra overhead for using a TcpChannel. You could even create your own channel like the IpcChannel now - .NET Remoting is extensible enough.
If this was a named application, you could use Windows messaging, global memory, DDE, and anything else you can think of (you can use these in .NET, but often the overhead of P/Invoking what's required and marshaling isn't worth the trouble; .NET Remoting provides a rich RPC experience, too).
