As it's a static method, you call it as I demonstrated, using the class name
if (Char.IsDigit(ch))
break;

Thxx Sir, its working 
|
|

I'm looking for an example how to write custom text edit control. Not a subclassed textbox but one that is written from the ground up.
|
|
|
|
|
Why do you need one ? I've looked and not found one in the past, but I got around the vagaries of the text box control ( namely that it draws itself out of the paint event ) with a bit of work.

Because I need to have a control over each line/paragraph etc. I want to make something like a custom text editor that outputs to a custom XML formats, depending on the context or the template. For now I cannot find any XML editor that can do what I need and I think the built in TextBox and RichTextBox controls won't do what I want to do.
This is what I want to do and the next thing that is independent of the above is that I want to see how text is handled in text editors and displayed on a form/control.

I have written one from complete scratch (iow painting every pixel). You can have a look at the source, but beware, the editor control alone is current almost 200kb (7000+ lines) in size. Follow either link below and see the link on the left of the page.

I know your control, leppie! Thank you! I was overwhelmed I hoped there was something simpler.
I much time have you spent researching, planning and creating it?
Have you ever thought writing an article about it?

It had a few incarnations, so I am not really sure  The project has been ongoing now for over 3 years
Cristoff wrote: Have you ever thought writing an article about it?
Dreamt about it, yes alot! Reality, it's so much info to transfer, I am not sure I will be able to ever explain it all to anyone 
I have decided to start writing small parts for documentation and post it to my blog. Hopefully one day all the info I have prodived on the blog can be compiled and edited
What I suggest, start off with a string[] for the lines, do a simple DrawString for the text. Find out what metrics you need like line height, and familiarize yourself with that. Then move on to selecting text, you will need some form of MeasureString here. After that make the caret, if needed, some people simply PInvoke this functionality. Finally if editing is required, do that. And then only start messing with colors and such.
Hope this helps a bit, I used a similar path.

I'd love to see this too... let me know when you publicize it

Thank you for the tips. How would you use string[]? For example you'll reserve 1000 lines then when 999 are used you'll expand the array by another 1000 lines. We'll this be fast and good enough?
Colors I might not need but who knows What I need to know is exactly what line I'm editing.

Your problem is that your message box is a jscript construct on the client, and your database is on the server. So, one way to do this would be to write a page which does your database operation then closes itself, and redirect to that page when the yes button is pressed, so you're running code on the server from the action that takes place on the client.

I'm sorry, I prefer not to respond to private emails, in general. I wouldn't use a jscript alert, I would use a popup window. In fact, your popup window could just handle a postback event when you click 'yes' without the need for another page. I expected you were creating a popup along the lines of this tutorial:
http://www.htmlcodetutorial.com/linking/linking_famsupp_70.html[^]
Then, if it's an aspx, you can set up your yes button to do your database action on postback.

i have to use the compile class to compile a project but i cant find the way to use it for my purpose
|
|
|
|

You need to provide some more information:
What is your purpose and what is the project like you're trying to compile?
How far did you get and what exactly doesn't work?

Hi,
I'm using reference types in c# instead of pointers...so in below code i'm sending the ptr which is a pointer but using ref key word now can any one tell me how to increament the pointer *(ptr+i) in c#?
int Largest(ref int ptr,int Icount)
{
int largest =0;
largest = *(ptr+0);
for(int i=0; i < Icount; i++)
{
if( *(ptr+i) >= largest)
{
largest = *(ptr + i);
}
}
return largest;
}

If you pass an int by ref, it's not really a pointer. You can increment the value, but you can't use it as a memory address, at least not easily.

hi,

I have tried to retrieve values using select link button.but,i want to use radio button instead of SELECT option.
thank u for any help.

Hi Rita,
I think you must be adding the radio button to some controls collection. am i right? If yes then i think that, the problem may be that you are adding the radio button to controls collection of the form on which you have the grid view. This might be one of the possibilities. I am not sure about it because you havent given much details. So if you can specify some code you are using it would be more easy.
Just check for the correct controls collection ( i hope this solves your problem)

hi,
thanks for considering.
I want to add radio buttons dynamically to a dynamic gridview which i have already created using bound columns.
I want to use the radio button to select the row's values in the grid & pass value to another page(i.e,to a login page).I was able to pass values using java script,but couldn't find a way to add radio button dynamically to the dynamic grid.I could get values using a SELECT button to select row's value.
thank u.
if (!IsPostBack)
{
CommandField field = new CommandField();
field.ShowSelectButton = true;
field.HeaderText = "Select";
GridView1.Columns.Add(field);
}

I am trying to retrieve the last modified date of an external webpage. I have found numerous ways to do this in vb, java, etc... but not in C#.
Heres some of them:
VB - http://www.freevbcode.com/ShowCode.asp?ID=362
ASP (so basically the same thing) - http://www.webdeveloper.com/forum/archive/index.php/t-3706.html
I've tried using HTTPWebRequest and HTTPWebResponse, since HTTPWebResposne has a LastModified property, but this is when the response was last modified, not the page. So I'm stuck... Any help would be awesome
