You may either use multiple controls to create a custom control (Windows Control Library project), or you may inherit any control and extend its functionality (Class Library project).
Apart from this you may also write a control from the scratch using System.ComponentModel class; however this would be toughest way to do this.
In case if you are planning to create a complex control, it is advisable to check some book related to control creation or use google and check some available samples of custom controls. This would give you more clear idea about the whole process.

Hi,
I am doing socket programing in that i am using
socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.KeepAlive, 1);
I have found info abt setting the keepalive time
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type KeepAliveTimeout, and then press ENTER.
5. On the Edit menu, click Modify.
6. Type the appropriate time-out value (in milliseconds), and then click OK. For example, to set the time-out value to two minutes, type 120000.
7. Restart Internet Explorer.
This is working but its taking more time ...i mean i have set it to 5 minutes and the socket got closed after 20 minutes
so if anyone knows how to set the proper time then plz do let me know
regards

Hello Friends,
I am developing an windows application in C#.NET and i am using text file to store some predefined responses. Now i want to avoid duplicate entries in text file i am able to achieve some some sort of success in doing that but not fully..
Suppose there is already a sentence in text file
:--- Hello how may i assist you?
now when i enter it again in same format then i get the response duplicate entry that right..
but when i change in case suppose i use
:-- hello how may i assist you?
it get saved in text file i want whenever the string is available in text file whether in UpperCase Or LowerCase it should not save in text file..

You need to build a dictionary of strings to strings. The key string is all lower case, with spaces and punctuation removed. This means you can't have duplicate entries, then you store the values in the collection, which remain nicely formatted.

Hello!
For that, use case for comparison i.e. change the strings to lower-case/upper-case before comparing both. You can use String.ToLower or String.ToUpper for that.
Hope that will be of some help!

Use the overloaded version of String.Compare() that takes a bool parameter. That way, you won't be creating extra objects.

Yes, this will work so long as the case is the only thing that differs.

Hi,

and i have made class1 object and assign it to class2 object.if i do make
chages in class2 then it also affact to class2 object.
but i dont want this.means if i make any changes in class2 then it should not affact to class1 object.
so for thos what should i do.
please help.

First, calling an object class1 or class2 is a bad idea.
Second, when you say obj1 = obj2; with reference types, you are not assigning one object to another, you are only assigning a reference to another.

Yes.

1. Don't assign the references.
2. If you absolutely must do something of the sort, consider implementing your Clone() method which creates a new object.

Vikram.

Well it's confusing at start but try to think of all "class"-objects as POINTERS or references (in C++).
You've got several possible solutions:
1.) Implement something like Clone (like proposed) - normaly you just add an copy-constructor so you can say MyClass Obj2 = new MyClass(Obj1) and use this in the Clone()-implementation - this way you can save one cast
2.) use struct instead of class - this will locate your objects in the local stack and copy the data instead of the reference when you say (obj2 = obj1)
3.) use the same data to construct the object 2 times with new
etc.

I have a Panel wherein i place textboxes dynamically. I have set AutoScroll property for the Panel to true. So when the size exceeds automatically Vertical Scroll bar appears.
I place dynamic textboxes in sequential order i.e one after the other row wise. I calculate the exact Location and place the control. This works fine.
The problem happens when i use the scroll bar to scroll down and then add few more TextBoxes. Now the location of the new added Text Box after scroll is not properly placed. Eventhough the calculation is the same. There is more gap between the previous and the next TextBox control. Why?

Hi,
First you should set the position of the Vertical Scroll into "0", then add the controls to the panel. Now it works fine.
this.panel1.VerticalScroll.Value = 0;
this.panel1.Controls.Add(objTextBox);

Thanks a lot for your help.
I tried setting the position of Vertical scroll to 0 and it worked.

Do you mean one FORM to another ? Use delegates ? There are other ways to do it, they are all wrong in comparison, with the possible exception of passing a value through a constructor. There is at least one good article on this on the site, try searching for it.

I have a question.. how do I get icons into C#. I'm talking about icons for toolbars in word editing programs.. Like the change color icon, left/center/right align icons, Bold, Italic, Underline icons.. I know they are stored on the computer somewhere, but where? Do I have attach these images to my program or can you use System.Drawing.Bitmap to display them since they are usually stored in the same folders on every computer using windows?
|
|
|
|
|
They'll be in a .dll (or various .dll's) somewhere, maybe in the MSOffice folder...
But your bitmap idea would work well... just take a screen shot and cut out the icons you want to use
 .

Hi,
I need to get a date out of a calendar control (set the CustomFormat to MM/dd/yy hh:mm tt), but when I call Convert.ToDateTime(dtpOrdStart.Value).ToString() I get the date and a random timestamp. Is there any way I can force it to 12:00:00 AM without having to go into the string and replace it myself?
thanx
