If you need floating-point numbers, you'll need to use a custom (masked) edit control. There are several here at CP.

OK. in CEdit when we choose number=true, and we enter a non-numeric character there is an error message like a tooltip. that writes something like not to enter non-numeric characters. Can i call that tooltip(or whatever it is), while not using number=true format.

Yes, check out CWnd::EnableToolTips() as well as the CToolTipCtrl class.

CString pre-pend

HI all,
is it possible to pre-pend to a CString as opposed to append, ie place a new string at the start of the string instead of the end. Thanks
Shane

Yes, just switch the order of the operands. Something like:

CString name("is David");
name = "My name " + name;

Make sense?

You can also use the Insert.

Insert( int, PCXSTR );
Insert( int, XCHAR );

Example:

CString test( "is a test" );
test.Insert( 0, "This " );

I have a VC++ application with tab views in the main window. I wish to be able to send some information and have it displayed in the lower portion of the main window. There are 3 shaded boxes for information along the lower right edge of the main window now. How can I access and write to those location?? Just not sure how to do it.

Thanks.
Jerry

Opening Access Database

I would like to get some code for opening a Access database. So that I can use an Excutable to open a the database rather than the .mdb Im not that familuar with Visual C++ but thats all I have avalible to me but I do know the basics Thanks for any help.

Re: Opening Access Database

For starters, create a new MFC AppWizard (exe) project via AppWizard. One of the steps will ask if you want database support. Reply in the affirmative. You will then need to select an existing DSN. After that, you select the table and the columns you are interested in. The default query that is generated for you is something like "SELECT * FROM <whatever table="" you="" chose="">".

If you have an existing MFC project, you can derive a new class from CRecordset. It will prompt you for the same DSN, table, and column that AppWizard did.

When you get this far, come back and ask some more questions. It's easier to go a few steps at a time.

Okay this probably sounds weird I know a little about ADO but all I want to do is have an EXE open a mdb and still have it open in access. Thanks again. By the way i would love to do my whole database with ado but there so many things i dont yet know how to do in C++ that I can do in Access. Smile | :)

Thanks again.

Then it sounds like you simply need to use ShellExecute() with the "open" verb. Use the absolute path to the .mdb file as the third parameter.

VC6 C++ ability to read .NET DataSet XML

OBRon28-Apr-05 4:30

I have an existing VC6 C++ application that I'm using to post http calls into a .NET web service. One of the methods on this web service returns a DataSet object which has pretty complicated XML; including base64 encoded binary blob fields. Has anyone attempted to create a C++ class that can emulate the C# DataSet class; and be able to parse that XML and provide accessors to the rows and column values? I am going to have to do this, but thought I would first see if there was any exising code I could make use of rather than re-inventing that wheel.

Thanks if anyone has a starter block of code they don't mind sharing.

Utility to convert VC++ to C#

Is there any utility which converts VC++ code to C# code. I do not expect all conversions basic conversion will do such as class, property, method migration.

Thanks

i believe no... you must rewrite all the VC++ Code into C#...
in fact you must redesign the code to get the best performance in C#...

Thanks Ravi,
I'd seen GetFileTime on VC6 but it only talked about WinCE !
I checked again at home where I have .NET2002 after your reply and it listed NT/2000/XP too. Odd Sniff | :^)
