set the "Send" button as the default button (with CWindow::SetDefId()) so that an Enter key press will press this button.

As toxcct said, handle the EN_CHANGE notification. In addition or as an alternative, you can handle WM_CHAR in your CEdit-derived class.
There you can 'eat' characters before CEdit even gets to see them.

Here is another notification event EN_UPDATE that is fired before updating the Edit control.
This notification message is sent after the control has formatted the text, but before it displays the text.

Try overriding the message handles for WM_CHAR, WM_PASTE, and WM_CUT.

hey guys i am working on VC++. need to implement a combo style color palette wherein i have only black n white colors and textures/patterns made out of the two colors
i have made bitmaps out of the patterns like a chessboard pattern. now i need to add these bitmaps to the combo box so that it coolk like a palette and handle the selection events when user clicks on any bitmap, so that it gets loaded on the selected object on which to apply the texture.
Can any one help please.
Thanx

Rather than putting those bitmaps on the combobox why don't you use the list control where you can set the images easily and handle them well.
Is it a project specific scenario?
Somethings seem HARD to do, until we know how to do them.

Thanx _AnShUmAn_ but u r right this a client specification to use such a control. for reference u can see how format cell option in Excel is done. i need a similar thing.
(open excel, select a cell, right click , select format cells, select patterns tab and drop down the format combo, u will see different patterns in black n white. I need that)
Thanx neways

Hello everyone!
Alright, I'm making a program, and it's supposed to work on many OS's, including MS-DOS... I wouldn't like to limit my Windows users to 8.3 filenames, so how can I get the maximum filename length in standard C? (not plusplus, just plain ol' C  )
Thanks!

Hi everyone i'm trying to update a record of a db in access using ADO and the SQL update command
the columns in the db are:
token - text
Spam - number
Ham - number
Pos - number (with decimal points)
app- number
in my program i have the following variables for each of the columns
_bstr_t token;
int valField2;
int valField3;
double valField4;
int valField5;
i try this code but i get an error at runtime
pCommand->ActiveConnection = m_pConn;
command="UPDATE tblDictionary SET Spam="+vlaField2;
command+=",Pos="+valField4;
command+=",app="+valField5;
command+="WHERE token='"+ token;
command+="'";
_bstr_t strSQLstatment=command.c_str();
variant_t vntRecordAffected;
m_pConn->Execute(strSQLstatment,&vntRecordAffected,adCmdText);
i get the following error Error:¦¨¨m¨V //i have no idea what this means but this is what i get
if i try to update with spacific numbers instead of using variables it works fine
pCommand->ActiveConnection = m_pConn;
command="UPDATE tblDictionary SET Spam=10,Pos=0.43,app=10 WHERE token='"+ token;
command+="'";
Any ideas what might be wrong.
Do i need to convert all variables that are to be inserted to type _bstr_t;
Please help me i really need to find this out thanks a lot

Can you log the strSQLstatment just before passing to the execute method.

Hey suhredayan® thanks for the reply
when i output the strSQLstatement i get:
ictionary SET Spam=,Pos=☺s=WHERE token='pill'//is totally messed up
Error:Θ·╒
Press any key to continue
and the output of strSQLstatment when i use fixed numbers looks good
UPDATE tblDictionary SET Spam=10,Pos=0.43,app=10 WHERE token='pill'
Press any key to continue
Can u see why this happens cause i have no clue thanks again

use sprintf() to format the command string.
