I have a text-box in a form and I want to change the typing language automatically into a certain language ?
Does any one know how to that ?

I don't understand what you mean by that. What benefit would that be? What do you expect it to do? A textbox doesn't have a built in spelling checker, so I don't see what it matters. You can type in what ever language you like.

I don't want a spelling checker.
I just need that when focusing the textbox the language will be changed to a specific language so that the textbox will contain character just of the german language for example.

Then you are going to have to define what characters are in the German language and exclude anything else yourself. There is no built in functionality for this.
In order to get this right you would have to conduct quite an intence linguistic study into the languages that you support. For example, some languages contain a lot of loan words. So, while in English accented characters are not used, they are used in some lone words such as fiancée or résumé. Would you block accented characters while set to English.

Hi.
Just wondering if anyone had any advice.
I am trying to read a text field from a .dbf file, the text field is 'encrypted' by a simple increase in the character code.
ie. 0 becomes m, 1 becomes n, by adding to the (int) value of the character.
I have tried using both an OleDB connection and ODBC connection DataReaders to import the data into a textbox so that the user can see the information before choosing to unscramble back to cleartext.
I have no problem populating the textbox but some characters are not being imported with the same encoding as in the file.
If I open the .DBF in a hex editor then I get :
79 77 77 78 80 7D 77 7F 77 7D 79 79 77 7F 7E
I have added a Diagnostic write to show what is in the text box:
79 77 77 78 C7 7D 77 7F 77 7D 79 79 77 7F 7E
As you can see, the fifth character value (hex) 80 is brought in as (hex) C7.
It seems to do this both when trying the OleDB and ODBC connection types for a DBF file.
Is it possible that I am missing an encoding option in the connection string or in the Data Reader?
Thanks in advance.
Tony.

You are confusing encoded data with character codes. They are not the same.
When you are reading the byte values from the file, you are getting encoded data.
When you are getting the character codes from a string, you are getting decoded unicode character codes. The character codes are 16 bit values, not 8 bit values.
How are you displaying the character codes? As they are 16 bit value, they will not fit in a two-character hex code. Are you certain that the character in question really has the character code C7 and not for example 48C7?
Do you have any problem with the values that you read, besides that the encoded bytes and the decoded characters are different?

Hi.
Thanks for the help, sorry about the confusion this is basically what I am doing. The .dbf file is an old ASCII 8bit file and this is what I am getting if I open up in a HexEditor.
79 77 77 78 80 7D 77 7F 77 7D 79 79 77 7F 7E
This information has been 'scrambled' by an increase in the character code. The file may or may not be scrambled, the idea of the program is for the user to check if it is and to choose to unscramble if they want to.
My program links to the database as below and assigns the strSample[0] to a textbox so the user can see if it is junk or an ID number as it would be if not scrambled.
string[] strSample = new string[3];<br />
strSample[0] = dBaseDataReader.GetString(dBaseDataReader.GetOrdinal("Col1name"));<br />
strSample[1] = dBaseDataReader.GetString(dBaseDataReader.GetOrdinal("Col2name"));<br />
strSample[2] = dBaseDataReader.GetString(dBaseDataReader.GetOrdinal("Col3name"));
When looking in the textbox the the information when scrambled looks ok but when check the character code of each character in the text box and display in a debug.
<br />
string DebugString = "";<br />
for (int i = 0; i < strSample[0].Length; i++)<br />
{<br />
DebugString += MarkGwilliam.com.Framework.Convert.Converter.DecToHex.Convert(((int)strSample[0][i]).ToString())+ " ";<br />
<br />
}<br />
System.Diagnostics.Debug.Write(DebugString);
I am getting
79 77 77 78 C7 7D 77 7F 77 7D 79 79 77 7F 7E
The strange thing is that it is even showing as a different character in the text box to in HexEditor or notepad, in there I can see the character (hex) 80 as Euro currency symbol but the character in my textbox seems to be Ç. If i actually type into the textbox with the old alt-128 trick then it does (the same as in this post) show Ç so how is it that when I ask for the decimal int for this character I am getting 199 instead of 128?
Confused!!!

You are still confusing byte values with unicode character codes. When you read the database file and get the value as a string, it's decoded from bytes into unicode character codes. Those are completely different in meaning, and you can't compare them.
What I think is confusing you is that the ASCII codes between 32 and 126 represent the same characters in the unicode character set. That is just a design decision for the layout of the characters in the uncide character set. The character codes in unicode could just as well have been completely different from the ASCII codes.

Hi there,
I've got a standard RTF control and am coding a basic text formatter.
In the event the user selects a section of text which has multiple fonts contained in it, SelectionFont will return null - that's documented and accepted behaviour.
However - how do I now set the font for the selected text to the new font in that case?
All the examples I've found use variations on the theme of:
richTextBox1.SelectionFont = new Font(
currentFont.FontFamily,
currentFont.Size,
newFontStyle);
which clearly won't work if richTextBox1.SelectionFont == null.
Please help!
Kind regards,
John.

Hi,
you can set it to any font you like:
rtb.SelectionFont=new Font("Arial", 24, FontStyle.Bold);
if you want it to resemble the original font(s), you might:
- remember the selection start and length
- apply a new selection, inside the original one (e.g. the first char)
so you can investigate what font that was using
- maybe iterate the previous step for different selection parts
- restore the original selection
- now apply a new font, based on what you discovered

Thanks Luc,
I was really hoping that something so complex wasn't required!
Kind regards,
John.

You need a menustrip. Drop it on a form and insert standard items. You will have to handle all the clicks yourself.
Looking at you last questions I suggest you buy a book about c# and winforms and/or learn searching.

i need to have general variable that can set or get it;s value from any form in my application it;s save it;s value between forms

You can have a public shared variable and any form will be see it but to exchange information between forms have a look at this: passingvaluesbetweenforms[^]
|
|
|
|

public static variables should do the trick.

Hi,
Here is the code snippet:
System.Diagnostics.Process p = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo sinfo = new System.Diagnostics.ProcessStartInfo();
sinfo.FileName = @"C:\WINDOWS\system32\calc.exe";
p.StartInfo = sinfo;
p.Start();
Thanks,

Hi,
Any idea how to directly show child table when clicking on the bloody parent collapse button in a datagrid control?? Do we always have to see the bloody relationship name link and click on it to open the child?? Can we hide the bloody toolstrip from the top of the child table?? Is there any other way to view datagrid table in more friendly way, say, have more than one child open simultaneously.. Is the bloody datagrid control that bloody??
Thanks for reading my bloody post;)

Yesterday I had a great experience designing an application in WPF. It's really cool to see how easy it was to create a databound treeview. However, I want to drag nodes within the treeview.
So far I did the following:
- Implement a mousemove eventhandler that initiates the drag operation
- Implement a dragover eventhandler to check if a dragged item can be dropped
- Implement a drop eventhandler that moves the item.
However the last eventhandler proves to be problematic. Although I have the correct data, I can't seem to grab the treeviewitem that th mouse is currently over. Anybody knows how I can get this?

Try searching through articles, I remember running across a good one dealing more or less with your issue just this week but sorry I cant remember the title not the author.
