1)how can I make properities or attributes in order(NOT SORT-LIKE) or take control them in order?
For example:
public string List
{
get { return m_strList; }
set { m_strList = value; }
}
public string List2
{
get { return m_strList2; }
set { m_strList2 = value; }
}
public string List3
{
get { return m_strList3; }
set { m_strList3 = value; }
}
it went like this:
List1
List3
List2
I dont know how did it do that.
I want to go like this
List2
List1
List3
can you tell me how to control these properties?
2)I am having struggle with changing color with using readonly
I am using those codes:
[ReadOnly(true)]
public string List
{
get { return m_strList; }
set { m_strList = value; }
}
I wanted to prevent the user to change the List but it changed the color black to light gray bec of readonly changed its color text. I tried to changed its text color(like ViewForeColor). No luck. what are your suggestions that how to change its text color?
Thanks in advance

how can i get the handle of popup form in my main form before it can get visible?...i want to destroy this form before user can see it...
|
|

|

In short, you can't. Also, it's very poor practice. You can get the handle, but it takes some searching with a couple of API functions. While this searching is going on, the window will have shown itself. After you get the handle, then you can send the WM_CLOSE message to it. But, there's no telling what will happen when you do this.
What are you trying to do? What window are you trying to supress? If it's part of your app, why would you want to quash a window that you put up?

infact i'm using a tool on my form and it is trial but before loading this tool it shows a dialogbox and i want to close it...
|
|
|
|
|
You're kidding me, right? You want help suppressing a dialog that says that this is a trail version? Pay the author for the control and get the version that doesn't have that dialog box.

Hi Man,
If you come to know the method to supress the trial message dialog box. Please also pass the info. After getting the tricks, I won't spend dollars purchasing the tool.....

Thanks for all helper here
now if i have textbox some times have value need parsing and another time null the parsing method desnt work when the textbox null and throw exception "input string was not in correct formt"
how can i stop parsing method if the textbox havnt any value
i tryed this code but it is not good to enter a zero in the field without value
if(txtPhone2.Text.Trim().Length !=0)<br />
{<br />
Phone2 = decimal.Parse(txtPhone2.Text.Trim());<br />
}<br />
else<br />
{<br />
Phone2=0;<br />
}
Thanks
|

Catch the exception:
decimal phone;
try
{
phone = Convert.ToDecimal(txtPhone2.Text);
}
catch(FormatException ex)
{
MessageBox.Show("Invalid phone number.");
phone = 0;
}This is called exception handling. Most .NET classes throw exceptions when something wrong happens (from invalid arguments to network errors) Take a look at the documentation, it's very useful to know about them.

This still isn't correct because you're only accounting for cases in which the user leaves the field blank. An exception will still be thrown if the user enters something like "I can't remember" (don't laugh - if you don't think a user would enter something like that, you're not treating input as the evil thing it actually is) or "(760)347-1234". The second one is a valid phone number (at least where I am), but it's certainly not a decimal.
You could certainly make the value 0 if the TextBox does not contain a valid number, but as you mentioned, having a bunch of zeroes in your database masquerading as phone numbers won't do anybody any good.
So the question on the table is: What value should we enter into a nullable field in the database when we don't have a value to enter? Null seems like a good choice to me.
You should rewrite your SQL command to submit a valid phone number (how you validate it is up to you) if you have one, or null if you don't.
As an aside, I can understand the impulse to rephrase a question and ask it again in a new thread if you don't get a satisfactory answer right away, but the only thing that really accomplishes is clogging up the message board and irritating the people trying to offer assistance. Unless you're asking an unrelated question, please keep it in the thread you already started.

I am in the process of creating a custom control that has various custom properties. I have successfully created the code for simple properties (i.e. strings, booleans) using :
[Bindable(true), Category("Appearance"), DefaultValue(">>")]
public string MyStringProperty
{
get {...}
set {...}
}
But, I need somebody to point me in the right direction for generating property accessors for lists.
As an example I have a property called MyListProperty which has 3 possible values (val1 (default), val2, val3). On the property page in VS .NET the user would use a drop down to select one of these values (or leave as default).
Also, there are a few default properties that are not relevant to the control, is there any way I can remove or at least hide them.
And finally, I would like to disable certain property depending on the value of another property. As an example, if I set MyProperty1 to False, then MyProperty2 and MyProperty3 would be disabled.
I suppose the bottom line here, is that I need to find a tutorial on how to use properties, so if you know of one please post the URL.

Does anyone have a suggestion on how to sequentially increment through the ascii character set in c#? For example, to iterate from "a" to "z", one could set up a loop to increment integers from 97 to 122 and take convert the resulting integer to an ascii character. C++ provides the ToAscii function but I don't see a corresponding way to this in C#.
|
|
|
|
|
Hold the phone, here is a clean way to do this:
for (int c1=97; c1<123; c1++)
{
char letter1=(char)(c1);
}
|
|
|
|
|
|
The class 'char' has few static methods.
One of them is 'IsChar' or something like that.

Hi,
I have a console remoting server with this in the main method -
TcpChannel MyTcpChannel = new TcpChannel(9932);
ChannelServices.RegisterChannel(MyTcpChannel);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(DataLayer)
,"DataLayer",WellKnownObjectMode.Singleton);
Console.WriteLine("Server Activated");
Console.ReadLine();
from my client side i can instantiate objects fine but i would like this server console app to display something as things happen - at the moment it just stops at "Server Activated" and then never says anything again. Is it possible to do this and if so how??
Im new to remoting so please excuse me if this question sounds ignorant or stupid.

Its easy if what I've understood is what u are trying. All console outputs must be implemented in the romote object, not the server. The remote object lives in the server side, so anytime one of its methods is called from the client side, the console output will show on the host side.
Hope this is what u were looking for.

I have a problem, I want to have a base class with child inherited classes.
The parent class has a method named Instanciate().
BaseClass
{
Instanciate();
};
ChildClass
{
ContainedClass MyClass
}
In the child class I want to call instanciate to instanciate an object of ContainedClass MyClass.
I would like the code to be generic and be in the Instanciate method of the parent class so I could have many child class with contained class of diferent types.
How can I do this ?
More importantly is it better just to put the code in the Child classes ?

Now i have two things in my mind. One is common and quite easy way to inherit class in normal way. Classical inheritance.
Eg:
<br />
using System;<br />
<br />
namespace ConsoleApplication6<br />
{<br />
class BaseCls<br />
{<br />
public BaseCls()<br />
{<br />
}<br />
public void Display()<br />
{<br />
Console.WriteLine("I am from base");<br />
}<br />
}<br />
class FirstDerivedCls:BaseCls<br />
{<br />
<br />
public BaseCls Bs;<br />
public FirstDerivedCls()<br />
{<br />
Bs = new BaseCls(); <br />
}<br />
public new void Display()<br />
{<br />
Console.WriteLine("I am from derived");<br />
<br />
}<br />
}<br />
class SecondDerivedCls:FirstDerivedCls<br />
{<br />
static void Main()<br />
{<br />
BaseCls B=new FirstDerivedCls();<br />
FirstDerivedCls F=new FirstDerivedCls();<br />
B.Display();<br />
F.Display();<br />
F.Bs.Display();<br />
}<br />
<br />
}<br />
<br />
}
Another idea is Ad-hoc or containment form of Inheritance. I already post few answers for containment or ad-hoc inheritance. I would like past the answer once again here.
<br />
using System;<br />
<br />
namespace Containment_and_Nested_Class<br />
{<br />
public class Radio<br />
{<br />
public Radio()<br />
{}<br />
public void TurnOn(bool on)<br />
{<br />
if(on)<br />
Console.WriteLine("Jamming.....ON");<br />
else<br />
Console.WriteLine("Quit Time.....");<br />
}<br />
}<br />
public class Car<br />
{<br />
private Radio theMusic;<br />
private int CurSpeed,MaxSpeed;<br />
private string PetName;<br />
bool dead;<br />
public Car()<br />
{<br />
dead=false;<br />
MaxSpeed=100;<br />
theMusic=new Radio();<br />
}<br />
public void CrankTunes(bool state)<br />
{<br />
theMusic.TurnOn(state);<br />
<br />
}<br />
public Car(string name,int max,int cur)<br />
{<br />
PetName=name;<br />
MaxSpeed=max;<br />
CurSpeed=cur;<br />
dead=false;<br />
theMusic=new Radio();<br />
}<br />
public void SpeedUp(int delta)<br />
{<br />
if(dead)<br />
Console.WriteLine(PetName+"is out of Speed");<br />
else<br />
{<br />
CurSpeed+=delta;<br />
if(CurSpeed>=MaxSpeed)<br />
{<br />
Console.WriteLine(PetName+"has over heated");<br />
dead=true;<br />
}<br />
else<br />
Console.WriteLine("\t Current Speed="+CurSpeed);<br />
}<br />
}<br />
<br />
<br />
}<br />
public class MAINCLASS<br />
{<br />
static void Main()<br />
{<br />
Car one=new Car();<br />
one.CrankTunes(true);<br />
for(int i=0;i<10;i++)<br />
one.SpeedUp(20);<br />
one.CrankTunes(false);<br />
}<br />
}<br />
}

Hi
I developed a interface in C#,When I compile the Code it is generating .DLL output.
Now I wand the output as .EXE, Can any one explain how to do ths.
Is it required any code changes?
Thanks in Advance

Do you use Visual Studio? If yes, you can change the output file type in the project properties (Project => Properties => General).

A .EXE must have one entry point, that means the project needs at least one class with a "Main()" method.
