it's the DataGrid control.
|
|
|
|
|
I want to extend a control (MenuItem, to be specific). But I want Visual Studio's Windows Forms Designer to use my new control (call it MyMenuItem) instead of MenuItem when using the Designer to create a MainMenu.
How does one do this?
Thanks in advance!

Unless the MainMenu designer has this feature in there already you'll have to create your own MainMenu type class and designer so that it creates MyMenuItems instead of MenuItems.

I am porting some code from c to c# and the original code makes a lot of use of #define macros - is there an equivalent in c# - at the moment I am turning the macros into fuctions but it I am wondered about the performance aspects of doing this
|
|
|
|
|
There is no equivalent to macros in C#
Creating them as functions should work well; the JIT does a good job of inlining such functions.

thanks eric (got your book by the way  )
what about optimisation? I am doing a lot of bit wise operations and rotations in 8,16, and 32 bit blocks
at the moment I have
private static uint ROL(uint x, int n)
{
return ( ((x) << ((n) & 0x1F)) | (x) >> (32-((n) & 0x1F)) );
}
private static uint ROR(uint x,int n)
{
return (((x) >> ((n) & 0x1F)) | ((x) << (32-((n) & 0x1F))));
}
would these be optimised to IL equivalents or would I have to drop to some IL layer eg is there an equivalent of _asm

You could consider compiling the library with Managed C++, and making wrapper-classes to the library, it might save you a lot of work. Managed C++ seems quite able to cope with plain C.

true - but that wasn't the point - the point was to convert from c to c# and learn the syntax differences between the 2 languages - a lot of places don't like mixing languages and like to concentrate on just 1 language across all layers - sad but true - I had the same problem with COM - I'd say but it is COM each side shouldn't care what it is written in as it has a binary interface layer and they'd say but it is written in VB (or ATL) and we don't use that here we use ATL (or VB)
according to MS they expect people to be using VB, C# or J# (according to an article I just read 33% in each block) and already I am hearing people say but we don't use C#.NET we are using VB.NET only

Hello Friends,
I want to open Outlook Express from within my application. Thats why I'm using following statement for the same :
System.Diagnostics.Process.Start("mailto:"+toNames+"?Cc="+ccNames+"&Bcc="+bccNames);
But it is giving me following exception:
"An unhandled exception of type System.ComponentModel.Win32Exception occured : The specific module could not be found"
Can anybody suggest what could have been the problem???
Outlook Express is indeed installed on my PC.So, what could be the reason of not finding the specific module or getting the exception.
Thanks in advance.

Kind of a quirk. Does not work while running the program in the compiler (in visual studio). But should work after it is built into an executable. Trying running the code as an executable.

The Jet Number - Integer type should be DBTYPE_I4 in OLE DB........ OleDbType.Integer
|
|
|
|
|
May be is DBTYPE_I2...

Is this a C# or C++ question?
If C# then:
System.Data.OleDb.OleDbType.Numeric

Hi all,
I just wanted to know if there is any built in compression in the .Net framework, like zip. I believe Java, has zip (jar) support built in.
Perhaps someone has done a zip library...
Any suggestions?
Thanx in advance
READ MSDN

There isn't anything built into the framework but you have a couple different options you can use.
ICSharpCode.net has an open source ZIP library you can use
You could also get the J# libraries and use the zip libraries there. I don't know about you, but the first choice seems more plausible

Hi all,
I have only access to command line C# compiler from .NET Frameworks SDK.
How to run a C# application with the help of this compiler?
I read somewhere that one can use makefile.
Can someone give me a example of how to run this make file?
thanks in advance

I suggest you use nant to make build files.

Hi andy,
Thanks for tips.
I searched the site you mentioned but I couldn't succeed to

Could you please mention which one should I download?
thanks for your help.

Hello resasalm_,
I suggest you use the SharpDevelop IDE its a free C# devlopment envirement and their page is http://www.icsharpcode.net/OpenSource/SD/default.asp I hope that helps you.
