I guessed that. You're not very likely to find one, sorry.

Am developing An application in C# and picking data from the database.
I have a bit data type to act as a flag.In the datagridview it displays a checkbox(good for me) but then I have failed to handle the click events of each row clicked to flag off the row so that it is not displayed again.
Need some help or a good article handling this.

Following is my issue.
-------------------------------------------
I have a unmanaged application ( C++ , .exe ) which has a class CMyClass
with a public member fMyFunct(). You can assume this C++ application is built with /clr option.
I need to instantiate CMyClass in a different managed ( C# ) application and call fMyFunct().
Many thanks if any of you can send me a sample which demonstrate above things ( Remember I can't manipulate C++ application apart from project settings. But you can do anything in C# application )
----------------------------------------------------

If it's an application ( not a dll ) then if you can't change the app, you're basically screwed. Your best bet would be to abstract the class/method out into a dll, so your C# application can construct an instance and call it. I don't think you can add a reference to an exe in a .NET app.

Sorry, you posted way too much code for anyone to bother reading it all.
Did you try setting a break point here and on any other code that sets that width of your control ? Does the control have a minimum or maximum width set in it's properties ?

I have setted a point there. the code was executed and value of "w" is right.but seem "TextSearch.Width" was not set value with "w".
TextSearch is TextBox, not has a minimum or maximum width properties.
|
|
|
|
|
What if you set that same size in the designer ? And, have you made sure no other code sets the size to something else ?

I am sure, not set same size and no other code set it.
I create a UserControl, it contain a ToolStrip.
the TextBox and SplitButton are in ToolStrip.
The SplitButton's Width is fix.
I resizing TextBox when ToolStrip resize.
Is the reason about ToolStrip ?
|
|
|
|
|
I find out the reason.
TextBox's autosize property default value is true.
set it false then ok.
thank you help again.

Strange - I thought of that but checked in a winforms app and couldn't see an AutoSize property. At least we got there, that's great.

At the end of te day, you're going to use DirectX, so I'd buy a DirectX book, look up some C# DX wrappers and go at it from that angle.

Hi Everyone,
I am planning to buy C# book. I am bit confused whether to go for C# 3.0 book or C# 3.5 book. Please suggest me some good books on both.
Is there any major difference between c# 3.0 and 3.5?
Thanks & Regards
Guhan

Go for the C# 3.0 book as C# 3.5 does not exist.
However, you may have your terminology confused. Did you mean .NET 3.5?
The table in this blog post[^] might help.

Sorry for the confusion. It is .Net 3.5.which should i go? .Net 3.0 or 3.5?

If you are using Visual Studio 2008 you have the option of using 3.5 and it will gracefully degrade to 3.0 or 2.0 if you want.
If you are using Visual Studio 2005 you only have the option of using 2.0 or 3.0 (with the Visual Studio extensions)
.NET 3.0 is additive. In other words, it does not change what was already in .NET 2.0 it only adds more to the .NET Framework.
.NET 3.5 is again additive. It only adds to what was in .NET 3.0 without changing anything that was already there.

Hello friends i am developing an windows application in C#.NET i want to align label text at run time according to user need.
i am using this command..
label1.TextAlign = System.Windows.Forms.HorizontalAlignment.Left;
but its gives an error....
|

1 - when you tell us you got an error, tell us what it was
2 - when you get an error, read it and see if you can work out what it says
3 - when you want to do something, read the MSDN instead of making stuff up.
this.lblBright.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
that's a line of code from my app. As you can see, and as the error is telling you, and as intellisense would also be making clear, the alignment is not set using the enum that you're trying to assign to it.

Wrong enum. You can check the type by hovering your mouse over the word "TextAlign".
label.TextAlign = System.Drawing.ContentAlignment.MiddleLeft;
|
|
|
|

Hi Dikshant
Are you want to set by the code?
you can set easilly by the property window.
thanks

Hi all,
I wrote a C# .Net service to automatically do some process in each 10 seconds. Say I start the service at 10:10:10 hours, then process are executed at 10:10:10, 10:10:20, 10:10:30 ......and so on until I stop the service.
But I want to start the service at 10 seconds interval. That is either on 00, 10, 20, 30... seconds time. Not like 11, 34, 56....
In other words, even I start the service manually at anytime my processing should start like times on 10:20:00, 2:45:30, 11:19:50, etc
I think it is clear for you now.
All the things I start from the constructor method. May following code segment helps you...
namespace RfService
{
public class RfService : System.ServiceProcess.ServiceBase
{
public RfService()
{
InitializeComponent();
const double INTERVAL = 10000;
TimerTicker = new System.Timers.Timer( INTERVAL );
TimerTicker.Elapsed += new ElapsedEventHandler( this.ServiceTimer_Tick );
}
private void ServiceTimer_Tick( object sender, System.Timers.ElapsedEventArgs e )
{
}
}
}
Can you guys and gals give me a help to do it. 
I appreciate your help all the time...
