Wow, you're really lost, aren't you ? :P
There are three programming languages you may be talking about here.
1/ C. That's what you said
2/ C++ - I guess it's possible
3/ C# - seeing as you asked in the C# forum.
If it's 3, then C is a different language, you need to say C#. As I said elsewhere, this is too complex a task for anyone to just write the source code in response to a forum question. However, my series of articles on image processing covers all of this ( in C# ), so just search for "graus image" in the site ( actually, google would probably do it as well ) and you may well find all you need. Unless you meant C. Then, ask in the C++ forum, as C++ is a superset of C, it's as close as we've got.
And for C or C++, BitBlt will invert with SRCINVERT, and will flip if you give it negative co-ordinates in the direction you want to flip.

I have to create a special but very basic text editor with the following features:
- export to special XML format (main feature)
- export as normal text format
- export to HTML (optional)
- export to RTF (optional)
- A predefined styles can be applied to the text (this is not necessary to be WYSWYG)
I need just directions for now (no source code), just an idea where to look at. Where should I start? What control to use for entering text? How to do the XML output? Do I need to write a custom text box control?
Thank you very much in advance!

hmmm, a refreshing question - most similar posts here ask for SOURCE CODE NOW PLEASE THX URGENT!!!111 
A text editor is basically just a big multi-line textbox and a main menu (New File, Save File, Exit etc), you should be able to "knock up" this quick sample before trying anything more complex.
Your "special XML format" is a main feature, but youve provided little detail on what you want to do, and depending on how difficult you want to go you could do anything up to a full-blown XML editor (Check out a demo of XMLSpy if you get a chance).
Based on some guesswork, you might want to have some simple "tags" defined, where the style would be added after..
[heading]This is my heading[/heading]
[bodyText]This is my body text[/bodyText]
This could also be interpreted to form an XML document, an HTML document and an RTF document. There are many object-oriented ways to achieve such a pattern (thing Formatter which takes the raw text and spits out the HTML,RTF,XML etc.)

I'll try to explain what I want to do. Maybe there is a better way but I do not know about.
I need to enter text. Let's say it is a poem. A poem has staves, verses a title, notes, etc. Currently if I do this I have to write all these XML tags manually. For a few things it is perfectly OK but with time it gets tedious work.
Example:
Great poem
by Greatest Poet of all times
A great poem I wrote,
a great poem you read.
To write another stave
you must be brave.
<code><title>Great poem<title>
<author>by Greatest Poet of all times</author>
<stave><verse>A great poem I wrote,</verse>
<verse>a great poem you read.</verse></stave>
<stave><verse>To write another stave</verse>
<verse>>you must be brave.</verse></stave></code>
Note: this is just an example but it shows basically what I want to do. I do not need to have a full XML editor.
I basically imagine it like having a text box where I type the text and on the left I select the style for each paragraph (row) like this:
title: Great poem
author: Greatest author of all time
verse: a verse
verse: a second verse
and the editor will add the rest of the tags as necessary.
Last note: Then the XML files will be transformed with XSLT into HTML or used as necessary.

OK, that all makes sense and you seem to have the right idea when it comes to building your XML and using it.
So what part do you think you need help on? Sounds to me like you could have a stab at trying to create this text editor and post any specific coding questions if you get stuck!

 I haven't touched .NET for 2 years so I don't remember much.
The main problem is: if I use textbox ot richtextbox how can I output it's contents into the required XML format. For example it's not clear to me. How should I recognize if a character has some special formatting and also how can I add for example a area where the number of a given line is displayed, it's style, etc.
I hope it is understandable.

Hello dear friend
Please notice below codes
We have a table with 3 fields as :
(field1:Int, field2:NVarChar, field3:Bit)
At first of your form add these namespaces:
<br />
using System.Data;<br />
using System.Data.SqlClient;
Now add these sample lines to your Button_Click() event :
<br />
string strInsert="INSERT INTO table (field1,field2,field3) VALIUES (@field1,@field2,@field3)";<br />
if (SqlConnection1.state.toString() != "Open")<br />
SqlConnection1.Open();<br />
sqlCommand cmd = new SqlCommand(strInsert,sqlConnection1);<br />
cmd.Parameters.Add(new SqlParameter("@field1",SqlDbType.Int,4,"field1"));<br />
cmd.Parameters["@field1"].Value = 1000;<br />
cmd.Parameters.Add(new SqlParameter("@field2",SqlDbType.NVarChar,10,"field2"));<br />
cmd.Parameters["@field2"].Value = "California";<br />
cmd.Parameters.Add(new SqlParameter("@field3",SqlDbType.Bit,1,"field3"));<br />
cmd.Parameters["@field3"].Value = true;<br />
cmd.ExecuteNonQuery();<br />
Don't remember to define SqlConnection
if you have any problem mail me
Bye Bye

Hi..
I want to use the CmdLoadFromResource() method of ths speech SDK 5.1 to make the xml file that includes the Grammar embeded but i dont know how to use this method in C#.
This code shows how i used this method:
[System.Runtime.InteropServices.DllImport("kernel32")]
private static extern long LoadLibrary(string lpLibFileName);
private void button2_Click(object sender, System.EventArgs e)
{
this.objRecoContext = new SpSharedRecoContext();
this.objRecoContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(RecoContext_Recognition);
this.objRecoContext.State=SpeechRecoContextState.SRCS_Enabled;
grammar = objRecoContext.CreateGrammar(0);
int hModule=Convert.ToInt32(LoadLibrary("ReviewWinApp.dll"));
int langID=409;
grammar.CmdLoadFromResource(hModule,"tryRecog.xml","CFGGRAMMAR",langID,SpeechLoadOption.SLODynamic);
grammar.State=SpeechGrammarState.SGSEnabled;
grammar.CmdSetRuleIdState(1,SpeechRuleState.SGDSActive);
}
When i click this button i got the error:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in ReviewWinApp.exe
Additional information: The specified resource type cannot be found in the image file.
Iam not good in COM programming.Could any one give me a C# code sample for using this method?

Hi everybody,
I want to call a secure web page through desktop application. Though .net automatically validates it but i want to get the exact status of error. In previous version certificatePolicy property of ServicePointManager was used for this purpose but now it is obsoleted. They have provided another function ServerCertificateValidationCallback but when I reach at the statement, it gives an error :
"System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

I used textbox to input data in my program, but as I used int input=covert.toint32(textBox.text) to accept the input value, I could not run this program. I am using vs2003, that code was in button_click event. Thanks for your help.

Try:
int input = Int32.Parse (textBox.Text);
Be sure to check for an exception.

WEll, if you typed it exactly like that, it won't work, as C# is case sensitive. To help people trying to help you, so we don't need to take wild guesses, you should define 'I could not run this program'. Did it compile ? Did it crash ? Did it do something you did not expect ?
If you use int.TryParse, you can avoid catching an exception
int input;
if (int.TryParse(textBox.Text, out input))
{
// This means that textBox.Text contained an int, it's now stored in 'input'
}

Thank you guys so much. I got my answer, and sorry for the typo.

C# is Case sensitive .Through with Syntaxes then u can proceed

I'm making a client-side application that monitors the status of a website and reports what it finds. I have that part working, but now I need to add the ability to have my application automatically submit information through a form on the site (textboxes and submit button style.) I have no clue how to do this, any suggestions?
Thanks
